    Angle Resolved Light Scattering in Turbid Media: Analysis and Applications2011Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Light scattering in turbid media is essential for such diverse application areas as paper and print, computer rendering, optical tomography, astrophysics and remote sensing. This thesis investigates angular variations of light reflected from plane-parallel turbid media using both mathematical models and reflectance measurements, and deals with several applications. The model of most widespread use in industry is the Kubelka-Munk model, which neglects angular variations in the reflected light. This thesis employs a numerical solution of the angle resolved radiative transfer problem to better understand how the angular variations are related to medium properties. It is found that the light is reflected anisotropically from all media encountered in practice, and that the angular variations depend on the medium absorption and transmittance and on the angular distribution of the incident light. If near-surface bulk scattering dominates, as in strongly absorbing or highly transmitting media or obliquely illuminated media, relatively more light is reflected in large polar (grazing) angles. These results are confirmed by measurements using a set of paper samples. The only situation with isotropic reflectance is when a non-transmitting, non-absorbing medium is illuminated diffusely. This is the only situation where the Kubelka-Munk model is exactly valid. The results also show that there is no such thing as an ideal bulk scattering diffusor, and these findings can affect calibration and measurement procedures defined in international standards.The implications of the presented results are studied for a set of applications including reflectance measurements, angle resolved color and point spreading. It is seen that differences in instrument detection and illumination geometry can result in measurement differences. The differences are small and if other sources of error - such as fluorescence and gloss - are not eliminated, the differences related to instrument geometry become difficult to discern. Furthermore, the angle resolved color of a set of paper samples is assessed both theoretically and experimentally. The chroma decreases and the lightness increases as the observation polar angle increases. The observed differences are clearly large, and it is an open issue how angle resolved color should be handled. Finally, the dependence of point spreading in turbid media on the medium parameters is studied. The asymmetry factor is varied while maintaining constant the optical response in a standardized measurement geometry. It is seen that the point spreading increases as forward scattering becomes more dominant, and that the effect is larger if the medium is low-absorbing with large mean free path. A generic model of point spreading must therefore capture the dependence on all of these medium parameters.This thesis shows that turbid media reflect light anisotropically, and angle resolved radiative transfer models are therefore necessary to capture this. Using simplified models can introduce errors in an uncontrolled manner. The results presented potentially have consequences for all applications dealing with light scattering, some of which are studied here.

    Point spreading in turbid media with anisotropic single scattering2011In: Optics Express, ISSN 1094-4087, E-ISSN 1094-4087, Vol. 19, no 3, p. 1915-1920Article in journal (Refereed)
    Abstract [en]

    Point spreading is investigated using general radiative transfer theory. We find that the single scattering anisotropy plays a significant role for point spreading together with the medium mean free path, single scattering albedo and thickness. When forward scattering dominates, the light will on average undergo more scattering events to give a specific optical response in reflectance measurements. This will significantly increase point spreading if the medium is low absorbing with large mean free path. Any fundamental and generic model of point spreading must capture the dependence on all of these medium characteristics.

    Anisotropic reflectance from turbid media. II. Measurements2010In: Journal of the Optical Society of America A, ISSN 0740-3232, Vol. 27, no 5, p. 1040-1045Article in journal (Refereed)
    Abstract [en]

    The anisotropic reflectance from turbid media predicted using the radiative transfer based DORT2002 model is experimentally verified through goniophotometric measurements. A set of paper samples with varying amount of dye and thickness is prepared and their angle resolved reflectance is measured. An alleged perfect diffusor is also included. The corresponding simulations are performed. A complete agreement between the measurements and model predictions is seen regarding the characteristics of the anisotropy. They show that relatively more light is reflected in large polar angles when the absorption or illumination angle is increased or when the medium thickness is decreased. This is due to the relative amount of near-surface bulk scattering increasing in these cases. This affects the application of the Kubelka-Munk model as well as standards for reflectance measurements and calibration routines.

    Anisotropic reflectance from turbid media. I. Theory2010In: Journal of the Optical Society of America A, ISSN 0740-3232, Vol. 27, no 5, p. 1032-1039Article in journal (Refereed)
    Abstract [en]

    It is shown that the intensity of light reflected from plane-parallel turbid media is anisotropic in all situations encountered in practice. The anisotropy, in the form of higher intensity in large polar angles, increases when the amount of near-surface bulk scattering is increased, which dominates in optically thin and highly absorbing media. The only situation with isotropic intensity is when a non-absorbing infinitely thick medium is illuminated diffusely. This is the only case where the Kubelka-Munk model gives exact results and there exists an exact translation between Kubelka-Munk and general radiative transfer. This also means that a bulk scattering perfect diffusor does not exist. Angular resolved models are thus crucial for a correct understanding of light scattering in turbid media. The results are derived using simulations and analytical calculations. It is also shown that there exists an optimal angle for directional detection which minimizes the error introduced when using the Kubelka-Munk model to interpret reflectance measurements with diffuse illumination.

    En multidimensionell kartläggning över hur ITkonsultföretag arbetar med kontinuerlig kompetensförsörjning2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Managing knowledge in an organization is always a challenge, the greater in an IT consulting company where the business idea is to offer special knowledge. In this study, it is examined how specialized expertise poses a risk to the business continuity and how IT consulting companies address any necessary organizational changes. It aims to produce a multidimensional survey of how IT consulting companies work with continuous supply of skills and answer the research question: Whether the IT consulting companies' dependence on specialist expertise poses a risk to the company's continuity? The study's results are based on interviews with people who have special expertise in a project, a questionnaire survey with all project members. The results show that the distributed work has an impact on the results, as well as previous studies show. However, impact can be minimized if all group members agree on how knowledge management will be conducted. The conclusion that this study provides is that IT consulting companies should, as a result of special expertise, be a driving force for the change processor. In this case, the ability to handle knowledge is ongoing in the project. This would lead to a stability where companies could become less dependent, even if it could not be removed. The contribution that this study gives to research is that companies and organizations should not focus on the problem of distributed forms of work without having a clear knowledge management model that is either formal or informal.

    Flödeseffektivisering genom metoder för effektivitetsberäkning och processkartläggningar: En fallstudie på ett massproducerande företag2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today it is important for production companies to create an overview of how the company is conducted to maintain its competitiveness. Mapping processes and material flows visualize production areas that create a direct value for the customer, while remaining areas or activities that do not add a direct value  should be minimized or eliminated. In order to identify material flows and non- value creation activities, complex models are required that can be combined in different ways. The study is based on a case study of an international mass-producing company that is partly located in the middle of Sweden. The factory studies four production lines, each producing the same product type but of different sizes. The aim of this survey is to create a deeper insight in a production process cost and material flows by combining a process-calibration method with methods for calculating the efficiency of processes. The first model used is a mapping process and material flow model to shorten lead times. The 2nd model used is a model that graphically shows which value and non-value creation activities to use the result in an efficiency calculation. The result consists of efficiency calculation, which shows that production Line 1 was streamlined by 19.12%, Line 2 by 6.68%, Line 3 by 18.73% and Line 4 by 4.77%. The goal of efficiency calculations is to achieve an optimal method where the efficiency is 100%.

    Trumprojektet: Att skapa ett eget trumset2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Går det att skapa ett akustiskt trumsätt med hjälp av enbart skar du hittar i ditt hem? Detta visade sig vara en mycket komplex uppgift där jag försökte skapa en hihat, virvel och en bastrumma genom att hitta, spela in och mixa trumliknande ljud hemma. Dessa ljud kombinerade jag sedan till ett trumkomp som jag använde som bas för ett kort enklare musikstycke jag improviserade. Jag spelade även in ett riktigt trumset för att kunna jämföra dem. Musikstycket visade jag sedan upp för ett antal lyssnare som sedan skulle gissa vilket som var vilket och varför det drog den slutsatsen. Det visade sig att majoriteten av mina testlyssnare kunde ganska enkelt höra skillnaden mellan trummorna även fast alla förstod vad jag försökte skapa med mitt hemmagjorda trumsound. Det som avgjorde det tydligast var enligt mina lyssnare var att de riktiga trummorna hördes tydlig att jag slog med trumpinnar och att anslaget var riktigt. Min slutsats är att du inte kan skapa ett helt trovärdigt trumset med hemmaprylar, men du kan komma en lång bit på vägen dit.

    How blockchain can increase food supply chain management actors’ competitiveness2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Fresh fish logistics is a complex and demanding supply chain. To add to this, consumers all over the world are increasingly concerned with food safety, environmental sustainability, and ethical production. On a global scale, the seafood industry handles close to 160 million metric tons annually, and approximately 20 percent of this is spoiled before reaching an end customer. Lately, there has been a lot of favorable discussions and fruitful experiments with regards to basing the supply chain on blockchain technology. Through a combination of a structured literature review and a SWOT analysis on the fresh fish supply chain, this thesis aims to review blockchain technology’s current status in the logistics industry, specifically food supply chain management, and evaluate advantages and disadvantages pertaining to the implementation and operation of a blockchain-based fresh fish supply chain management solution. Furthermore, this thesis seeks to initiate a general discussion on the applicability of blockchain on fresh fish food supply chain management systems.

    While blockchain might, at first glance, seem as the ideal solution to today’s challenges, a blockchain based supply chain in the fresh fish industry is facing several challenges of its own which it needs to overcome in order to make it suitable for wide-scale implementation.

    Är du beredd när det smäller?: Utmaningar inom incidenthantering med fokus på IT-konsultbolag2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Information security incident management is important for organizations and its importance is increasing. Information security incidents are increasing both in number and in scope and in 2018 GDPR and the NIS-directive require organizations to report incidents to a supervision authority. This study highlights IT-consulting companies and their vulnerable position as subcontractors. The study aims to address the lack of empirical research in incident management and to inform future theory development. The goal of the study is to answer the research questions (1) what challenges do IT-consultancy companies experience with their incident management? (2) What challenges are specifically related to the GDPR and the NIS-directive? And (3) what challenges are specific for consulting companies? Challenges with the incident management are identified and clarified by qualitative interviews with experts and a survey. The analysis of the results shows that some of the challenges are consistent with previous studies, while some are new and that the survey partly support the experts' opinions. The conclusion of the study is that the majority of the companies’ improvement opportunities are linked to internal and external communication, cost focus, absence of a major incident, awareness, GDPR, the role of consulting company and internationally recognized difficult activities. The research contribution of the study consists of identified challenges in the field of incident management derived from IT-consultancy companies. The result of the study are recommended to IT-consultancy companies that would like to improve their incident management process by gaining an understanding of incident management issues.

    Elektronisk signering: En studie om införandet av elektroniskt signerade protokoll i svenska kommuners verksamhet2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digitalization of the working flow is a developing area. Digitalization of a public authority’s working flow can lead to a more effective flow. The purpose of this study is to identify factors when implementing electronic signatures of the protocols in Swedish public authorities. In order to fulfill this purpose, a case study has been conducted at one municipality, interviews have been held with people from another municipality as well as three commercial suppliers of electronical signatures, and a literature study has also been made. A qualitative content analysis was made on the material from the case study and the interviews with a resulting list of important factors to consider when implementing electronic signatures to the protocols. The factors are: Security, laws, usability, cost, functionality in the system and long-term preservation. These factors have been examined more closely and the results from the examination show that these factors could be relevant to all public authority’s in Sweden who are about to implement electronic signatures. However, all the factors are not equally meaningful. Since the laws are essential for the use of electronic signatures, they have to be seriously considered. Security is closely related with the demands of the laws. Therefore the requirements of the law can be used to fulfill the need for good security. Other factors that are important are long-term preservation, cost and functionality in the system.

    Ständiga förbättringar: Stödjande och hindrande faktorer för medarbetares proaktivitet2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande uppsats är att undersöka vilka faktorer som verkar stödjande respektive hindrande föär medarbetares och teams proaktivitet. Vi har besvarat följande frågor:

    Hur skattar medarbetare sin egen och teamets grad av proaktivitet i dagslläget?

    Vilka faktorer anser medarbetarna verkar stödjande respektive hindrande för medarbetarnas egna och teamets proaktivitet?

    Tillvägagångssättet har varit en fallstudie med kvalitativ ansats, där datainsamlingen skett via enkät och där frågorna utgått från tidigare forskning.

    Resultatet visar att medarbetare ser olika på sin egen och teamets/kollegornas proaktivitet. Resultatet visar också att respondenterna betonar delvis andra faktrersom avgörande för proaktiviteten än tidigare forskning påvisat.

    Studiens generaliserbarhet begränsas av att enkätundersökningen enbart vände sig till 28 personer inom applikationsförvaltning på ett IT företag. Vi ser dock ett värde i att studien fann andra faktorer som påverkar medarbetarnas och teamens proaktivitet än vad genomgång av tidigare forskning påvisat.

    Abstract [en]

    The study aims at identifying the impacts accruing from the implementation of an ERP-system on a large production company that previously managed information in several unintegrated systems. This is investigated from the perspectives and frameworks of Lean Administration, information security and information- and data quality. The study has been conducted at SCA Östrands marketing department, SCA is currently investing 7,8 billion Swedish kronor in the Östrand pulp mill and will be leading the world market. SCA aims to produce 1 million tons of pulp per year with the new mill. As production increases, more data and information will be handled, and support processes must be improved and developed. Process flows were mapped with the process mapping method BPMN and analyzed at a current state and a future state. In the current state, several unintegrated systems are used, in the future, many parts have been integrated and automated. Three main processes were identified and analyzed according to the earlier mentioned frameworks. The analysis shows that the information security is improved according to the CIA-triad, Information- and data quality is improved, and the working method is Leaner after the implementation. In order to calculate efficiency, Data Envelopment Analysis, DEA method has been used with the CCR and ARI models. The results of DEA-CCR and DEA-ARI shows that process flow of the current state is between 48,3% and 57,1% effective compared to the future state, which is 100% effective in the models.

    Att arbeta med ”Synchronization management”2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay revolves around Synchronization management & Synchronization licensing, or in short sync. The development of sync as a career choice and profession has been fast and is still ongoing. It is not until later years that sync has become a proper profession, whereas before it was just part of a publisher or sales person’s regular work.

    In short, sync deals with the commercial use of copyright protected music. A synchronization manager negotiates fees and licensing agreements while handling the dialogue between commercial businesses, publishers and in some cases song writers. Once a deal has been made a Synchronization license is granted by the owner of the copyrighted music, allowing the licensee (the person wanting to use the material) to use the music according to the agreement. A Synchronization license is most commonly used when a company wants to use music in either commercial, television or any kind of visual media.

    To get a better understand of Synchronization management a series of interviews were conducted to get three different perspectives. The first interview helped establish what a synchronization manager actually does, and was held with a person who works with the profession in question. To better grasp the song writing point of view when it comes to sync an interview with a person who was writing for sync briefs was conducted. Lastly, a publisher was interviewed to help understand synchronization licensing from a publishing point of view.

    The result generated by the interviews in combination with already written articles about Synchronization management helped get a better understanding of the profession and how different individuals are using it in their daily life in music. The main question of this essay was to establish if sync is a reliable source of income for “up-and-coming” song writers and music producers.

    Converting conventional stereo pairs to multi-view sequences using morphing2012In: Proceedings of SPIE - The International Society for Optical Engineering, SPIE - International Society for Optical Engineering, 2012, p. Art. no. 828828-Conference paper (Refereed)
    Abstract [en]

    Autostereoscopic multi view displays require multiple views of a scene to provide motion parallax. When an observer changes viewing angle different stereoscopic pairs are perceived. This allows new perspectives of the scene to be seen giving a more realistic 3D experience. However, capturing arbitrary number of views is at best cumbersome, and in some occasions impossible. Conventional stereo video (CSV) operates on two video signals captured using two cameras at two different perspectives. Generation and transmission of two views is more feasible than that of multiple views. It would be more efficient if multiple views required by an autostereoscopic display can be synthesized from these sparse set of views. This paper addresses the conversion of stereoscopic video to multiview video using the video effect morphing. Different morphing algorithms are implemented and evaluated. Contrary to traditional conversion methods, these algorithms disregard the physical depth explicitly and instead generate intermediate views using sparse sets of correspondence features and image morphing. A novel morphing algorithm is also presented that uses scale invariant feature transform (SIFT) and segmentation to construct robust correspondences features and qualitative intermediate views. All algorithms are evaluated on a subjective and objective basis and the comparison results are presented.

    Agencies, it’s Time to Innovate!: Exploring the current understanding of the Swedish government’s call for innovation2015In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703, Vol. 7, no 1, p. 34-49Article in journal (Refereed)
    Abstract [en]

    Purpose

    Innovation is currently at the top of many agendas worldwide: not only in the private sector, but also when it comes to increasing quality, efficiency, and effectiveness in public administration. InSweden, this is reflected in the recent call from the Government for innovation in public management. However, innovation has not traditionally occurred to any significant extent on the strategic level of Swedish public management. Furthermore, governmental administration is a complex system in need of coordination and alignment for this new call to be effectively realized in practice.  

     

    The purpose of this paper is hence to explore the phenomenon of innovation in the current Swedish governmental administration system. More specifically, the paper explores the current understanding within the system of what innovation is, as well as why and how it should be achieved.

     

    Methodology/approach This study has been based on a qualitative approach with a case consisting of three embedded units: the Government itself, a ministry and a government agency. The data have been collected from documents and interviews.

     

    Findings

    The study shows that there is currently a notable disparity when it comes to how aspects of innovation are understood at different levels within the Swedish governmental administration system. Furthermore, the recent business development to increase the standardization of work processes is perceived as having created poorer preconditions for working with innovations.

     

    Practical implications

    The results highlight critical areas of disparity and possibilities for improvement towards a shared understanding and aligned innovation actions within the system.

     

    Originality/value

    The articlecontributes knowledgeabout the current understanding of innovation in the Swedish governmental administration system.

    The challenge of integrating innovation and quality management practice2016In: Total Quality Management and Business Excellence, ISSN 1478-3363, E-ISSN 1478-3371, Vol. 7, no 1-2, p. 34-47Article in journal (Refereed)
    Abstract [en]

    Following in the footsteps of ‘New Public Management’, where quality management and quality control have become widely implemented concepts among public authorities, there is now a subsequent government demand to also be innovative. However, integrating and achieving a balance between improved quality and increased innovation is not an easy task. Previous research indicates a complex and ambiguous relation, raising questions as to how to optimally combine these two approaches organisationally, operationally, and culturally. Is there an ‘edge of chaos’ where there is maximal flexibility for innovation while maintaining sufficient order for quality? The purpose of this paper is to examine the potential integration of innovation and quality management practice within the public sector. The paper is based on a multiple case study design, confronted with existing literature, and shows that the current quality management practice is perceived as being related to standardisation, leading to a decrease in the space for innovation. Second, that there is an expectation and belief that innovation and quality management can be handled in parallel and reinforce each other instead of being mutually detrimental.

    Ledningens påverkan på en förändring: En fallstudie om engagemang och kultur2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Previous research shows that 50-­70% of all changes made in organizations fails. Many factors play role in creating successful and lasting changes, but leadership is a key factor. The purpose of this study is to examine leader’s conditions in terms of commitment and organizational culture, to make successful and lasting changes. Previous research about successful and failed organizational changes have been studied. A survey and additional interviews have been made to investigate leader’s conditions in the current and future situation. The study has shown that leaders can create commitment by e.g. continuously inform the co-­workers about the change, visualize progress and have a reward system connected to the change. The conclusions are that that the chosen organization have relatively good conditions in terms of commitment and culture, but there is room for some improvements (for example teach leaders about commitment and change management). Another conclusion is that a model for change is not a guarantee for successful and sustainable changes. To make changes successful there’s got to be commitment and the organization got to anchor the changes into the culture.

    Aggregation of Group Prioritisations for Energy Rationing with an Additive Group Decision Model: A Case Study of the Swedish Emergency Preparedness Planning in case of Power Shortage2016Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The backbone of our industrialised society and economy is electricity. To avoid a catastrophic situation, a plan for how to act during a power shortage is crucial. Previous research shows that decision models provide support to decision makers providing efficient energy rationing during power shortages in the Netherlands, United States and Canada. The existing research needs to be expanded with a group decision model to enable group decisions. This study is conducted with a case study approach where the Swedish emergency preparedness plan in case of power shortage, named Styrel, is explored and used to evaluate properties of a proposed group decision model. The study consist of a qualitative phase and a quantitative phase including a Monte Carlo simulation of group decisions in Styrel evaluated with correlation analysis. The qualitative results show that participants in Styrel experience the group decisions as time-consuming and unstructured. The current decision support is not used in neither of the two counties included in the study, with the motivation that the preferences provided by the decision support are misleading. The proposed group decision model include a measurable value function assigning values to priority classes for electricity users, an additive model to represent preferences of individual decision makers and an additive group decision model to aggregate preferences of several individual decision makers into a group decision. The conducted simulation indicate that the proposed group decision model evaluated in Styrel is sensitive to significant changes and more robust to moderate changes in preference differences between priority classes.

    Data Mining for Network Intrusion Detection: A comparison of data mining algorithms and an analysis of relevant features for detecting cyber-attacks2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Data mining can be defined as the extraction of implicit, previously un-known, and potentially useful information from data. Numerous re-searchers have been developing security technology and exploring new methods to detect cyber-attacks with the DARPA 1998 dataset for Intrusion Detection and the modified versions of this dataset KDDCup99 and NSL-KDD, but until now no one have examined the performance of the Top 10 data mining algorithms selected by experts in data mining. The compared classification learning algorithms in this thesis are: C4.5, CART, k-NN and Naïve Bayes. The performance of these algorithms are compared with accuracy, error rate and average cost on modified versions of NSL-KDD train and test dataset where the instances are classified into normal and four cyber-attack categories: DoS, Probing, R2L and U2R. Additionally the most important features to detect cyber-attacks in all categories and in each category are evaluated with Weka’s Attribute Evaluator and ranked according to Information Gain. The results show that the classification algorithm with best performance on the dataset is the k-NN algorithm. The most important features to detect cyber-attacks are basic features such as the number of seconds of a network connection, the protocol used for the connection, the network service used, normal or error status of the connection and the number of data bytes sent. The most important features to detect DoS, Probing and R2L attacks are basic features and the least important features are content features. Unlike U2R attacks, where the content features are the most important features to detect attacks.

    A Novel Instrumented Human Head Surrogate For The Impact Evaluation Of Helmets2018In: Proceedings, Volume 2, ISEA 2018 / [ed] Dr Hugo Espinosa, David R. Rowlands, Jonathan Shepherd, Professor David Thiel, 2018, Vol. 2, p. 269-, article id 6Conference paper (Refereed)
    Abstract [en]

    A novel Human Head Surrogate was obtained from available MRI scans of a 50th percentile male human head. Addictive manufacturing was used to produce the skull, the brain and the skin. All original MRI geometries were partially smoothed and adjusted to provide the best biofidelity compatible with printing and molding technology. The skull was 3D-printed in ABS and ten pressure sensors were placed into it. The brain surrogate was cast from silicon rubber in the 3d-printed plastic molds. Nine tri-axial accelerometers (placed at the tops of the lobes, at the sides of the lobes, in the cerebellum and in the center of mass) and a three-axis gyroscope (at the center of mass) were inserted into the silicon brain during casting. The cranium, after assembly with brain, was filled with silicon oil mimicking the cerebral fluid. Silicon rubber was cast in additional 3d-printed molds to form the skin surrounding the cranium. The skull base was adapted to be compatible with the Hybrid-III neck and allow the exit of brain sensors cabling. Preliminary experiments were carried out proving the functionality of the surrogate. Results showed how multiple accelerometers and pressure sensors allowed a better comprehension of the head complex motion during impacts.

    Ljuddesignens påverkan på spelarupplevelse: En utforskande analys av ljuddesigners arbetsmetoder och den resulterande ljudbildens effekter på spelupplevelse2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal of this study was to research the connection between the methods, goals and thought processes of a sound designer throughout the production of a game and how the soundscape of the final product was received by the public as well as games journalists. A survey with questions about the sound of select games was sent out and received over a hundred answers and reviews of the same games was collected and assessed to get a picture of what the public thought about theses game’s sound. Only one of the seven sound designers that was approached responded and agreed to an interview.

    The information gathered in that interview indicated that the publics opinion of the soundscape of a game is in part determined by the clarity of the goal for the soundscape before production began. The study indicates that if a sound designer has a firm idea of how the world that is being sonically portrayed is supposed to sound then that reflects well in the judgment of journalists and the opinion of the audience. Even so, more studies of the same sort are required to solidify this result and to rule out alternative methods of explanation.

    Tapetserararbetet under rokoko och nyrokoko: Vad skiljer i material och textilier2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats handlar om skillnader inom tapetserarabetet mellan rokoko och nyrokoko stilen, med fördjupning inom stoppningsmaterial och textilier. I texten beskrivs vilka material och textilier som varit tillgängliga under 1700-talet och hur de utvecklats under 1800- till 1900-talet, samt hur de påverkat tapetserararbetet hantverksmässigt.

    Arbetet är uppdelat i olika kapitel, där undersökning/genomförandet är den mest omfattande delen. Där har jag använt mig utav litteraturstudier, intervjuer, föreläsningar och utfört ett praktiskt arbete av en nyrokoko soffa som jag dokumenterat under arbetets gång.

    I resultatet har jag kommit fram till att rokoko och nyrokoko inte har så mycket gemensamt vad gäller stoppningstekniker, men att samma typer utav material har använts ända fram till 1900-talet.

    Till sist reflekterar jag över vad jag kommit fram till i mitt resultat

    Abstract [sv]

    Jag har renoverat en ovanlig fåtölj av Carl Malmsten vid namn Redet. I min uppsats redogör jag för mitt tillvägagångssätt för fåtöljen, vilket har inneburit ett nytt resårhus och en ny traditionell stoppning i kroll. Jag beskriver hur man gör när man ska malla upp och sy en rygg bestående av pipor samt disskuterar olika sätt man kan lösa problem som uppstår när man bland annat använder sig av en snodd som har en sömsmån. Jag redogör för hur man ska göra när man syr en plymå samt det övriga klädnadsarbetet.

     

    Jag har valt att mer eller mindre fokusera min uppsats på hur man ska hantera renoveringen av en ovanlig och dyrbar möbel. Det absolut viktigaste är göra en noggrann förstudie där man detaljerat dokumenterar hur möbel ser ut och är gjord i varje stadium samt forska efter så mycket information som möjligt om möbeln. Att hitta så många referensbilder som möjligt underlättar arbetet då man hela tiden ska sträva efter att möbeln man jobbar med ska vara så trogen originalet som möjligt.

    Integrering av Lean-DMAIC för ett effektivare informationsflöde2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Throughout history companies have come to realize the importance of work revolving quality in order to remain competitive on the market. Process development is a natural part of quality management. There exists several different philosophies and tools to make use of in this work, examples are Lean Production and Six Sigma. The state of research of the programs are well studied, but the combination of Lean and Six Sigma's work methodology DMAIC has many unknowns. The objective with this study has been to integrate Lean with DMAIC. The study's purpose has been to investigate whether DMAIC is consistent with theories about Lean. The question this study tried to answer is how Lean-DMAIC can be used to minimize inconsistencies in flow of information in a global production company. The purpose of this paper has mainly been answered with the aid of the literature study. The question at issue has mainly been answered by the case study. The objective has been answered with a combination of the case- and literature study. The work procedure is based on DMAIC´s methodology, while Lean provided the tools for success in combination with the philosophy´s train of thought that permeate the work. The results of the study illuminated that Lean-DMAIC works in a simultaneous fashion in order to find inconsistencies in existing flows of information; with these results the study's question has been answered. By the end of the study it was possible to ascertain that a better question for this particular study would have been how Six Sigma is consistent with Lean, as DMAIC is a method, thus they cannot be directly compared. In this study, DMAIC provided the step-for-step method for how to model the work and in what manner the process was examined. Lean on the other hand provided the right tools and the train of thought in order to succeed. This culminated in that several improvement measures could be produced based on the study's results.

    Modellutveckling för granskning av ekonomisk tillväxtpotential2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To increase the economic growth of a company today is a complex task to be assigned. Many variables and factors to be taken into account. This study is based on a case study out of an analysis model made by Timrå County to assess corporate growth potential. Purpose of this study was to examine the unique set of criteria in the model. The study intendeds to scientifically validate the link between the unique criterion-set in the analysis model and economic growth potential. ROE as a measure to assess economic growth and the companies with the highest ROE value was considered to possess the greatest growth potential. The study was conducted to find a correlation between the models criteria and increased economic growth for companies. A regression analysis between economic growth and the criteria’s in the model was performed, to find a connection. The regression analysis provided the study with an equation where weights of the growth obstacles were distributed. The equation used a GAP value for respective growth barriers, which could appreciate the growth of a company. Sued the estimated growth with the ROE value the analysis model to be properly structured. The results showed that this was not the case, but it appeared instead that there were large gaps between the analysis model and economic growth. Several of the companies analyzed by the model showed negative growth value according to ROE, and only one company had a ROE value among top 20. The relationship between the models set of criteria and growth potential, had very low correlation. K-squared only found a correlation of 0.00008. This is considered too weak for the development of the unique set of criteria. The study instead recommends new set of criteria for future analyze models.

    A simulation and machine learning approach to critical infrastructure resilience appraisal: Case study on payment disruptions2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study uses a simulation to gather data regarding a payment disruption. The simulation is part of a project called CCRAAAFFFTING, which examines what happens to a society when a payment disruption occurs. The purpose of this study is to develop a measure for resilience in the simulation and use machine learning to analyse the attributes in the simulation to see how they affect the resilience in the society. The resilience is defined as “the ability to bounce back to a previous state”, and the resilience measure is developed according to this definition. Two resilience measurements are defined, one which relates the simulated value to the best-case and worst-case scenarios, and the other which takes the pace of change in values into consideration. These two measurements are then combined to one measure of the total resilience. The three machine learning algorithms compared are Neural Network, Support Vector Machine and Random Forest, and the performance measure of these are the error rate. The results show that Random Forest performs significantly better than the other two algorithms, and that the most important attributes in the simulation are those concerning the customers’ ability to make purchases in the simulation. The developed resilience measure proves to respond logically to how the situation unfolded, and some suggestions to further improve the measurement is provided for future research.

    Värdering av kriterier vid stora investeringar: En jämförelse mellan olika intressenters uppskattningar av kriterier2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In what way does different stakeholders assess a decision and its consequences, and how do these assessments differ? When a company stands before a big decision, they need to consider aspects that are economic, ecologic and social. To make a good decision they need to consider the society and its different stakeholder groups. This study examined how different groups values and weights different criteria. The study has been done with the project Sundsvall logistics park as a case, with criteria related to that project. The goal of the study was to find a way to value and weight different criteria and then compare how the company and the stakeholders assesses these criteria. This has been done through interviews with relevant people that has got extra knowledge about the project Sundsvall logistics park, and through a survey that has been sent out to residents of Sundsvall. The informants and respondents got to assess values and weights to the criteria relative to an indirect alternative where the logistics park isn’t built. The data was then compiled using multi attribute utility theory as a tool to present the comparison. The result of the study suggests that the differences between the valuations and weightings of the criteria is partly due to an uncertainty in how the logistics park would affect the criteria, but that the biggest reason probably depends on what perspective the person is viewing the logistics park from. If the person is viewing the logistics park from an industrial perspective, the criteria related to industrial development is getting more important and is going to take up more room in the analysis. If the person is viewing the logistics park from an individual and social perspective, the criteria related to that is more important and takes up more room in the analysis.

    Assessing Stakeholder Preferences in Urban Planning: A Multi-Attribute Utility Approach2019Conference paper (Refereed)
    Abstract [en]

    In urban planning, decision makers often need to take a variety of aspects into account, including stakeholder attitudes. The purpose of this paper is to compare how decision makers and the public assess different criteria in an urban planning project. The study was carried out through interviews and a survey about an urban planning project. By compiling data using multi-attribute utility theory, it was possible to reveal similarities and differences between the decision makers and the public. The findings reveal that the perceived value of the project differed greatly between these two perspectives: The public’s opinion was closer to a status quo perspective, while the decision makers were more optimistic about the project. While some of the differences can partly be explained by uncertainty about the project and the criteria, the results reveal the importance of including thepublic in an early stage of these initiatives. Furthermore, the multi-attribute utility approach is a useful tool for compiling assessments, but additional data is needed for gaining further understanding of stakeholder preferences. Therefore, a mixed-methods approach to collecting stakeholder preferences is suggested.

    Musikens inverkan på lyssnaren.: En litteraturstudie kompletterad med en implementering av strukturerad lyssnande.2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Ohälsa har de senaste åren ökat bland befolkningen nationellt. Det finns ett större

    behov för alternativa behandlingar för att kunna ge lindring. En av dessa alternativa metoder är

    implementering av musik. Det talas om ’’musikmedicin’’ - ett sätt att främja, förstärka och berika

    patienters status.

    Bakgrund: Det finns omfattande studier om musikens påverkan på människan. Studier på

    fysiologisk och psykologisk respons vid musiklyssnande har fått ett större intresse de senaste tjugo

    åren. Tidigare så har musikerns roll varit frikopplad från studierna då dessa mestadels

    implementerat inspelade medier.

    Syfte: Att identifiera hur musiken påverkar lyssnaren.

    Metod: Litteratursökning har innefattat litteratur på ämnet musik och hälsa, avhandlingar på nätet

    och även strömmande videos. En enkätmetod med implementerande lyssningsmoment har

    upprättats med en testgrupp. Testgruppen bestod av nio deltagare, 5 kvinnor och fyra män, som fått

    lyssna på ett eget utvalt verk 2 gånger om dagen i 3 veckors tid.

    Resultat: Musik fungerar som ett medie som kan påverka kroppen och sinnet i ett hälsofrämjande

    syfte. Resultat talar för att musiklyssnande kan främja individens hälsa genom fysiologiska

    reaktioner, som exempelvis dopaminfrisättning. Det faktorer som spelar in för att få önskvärda

    resultat är bland andra musiksmak, social - och kulturell koppling och emotionell koppling till

    musiken. Det finns mallar som går att förhålla sig till för att förstå sambandet mellan musik, hälsa

    och individen för implementering. Resultaten från enkätmetoden talar för att majoriteten av

    deltagarna har upplevt förbättrade resultat med sänkta stressnivåer än innan utfört moment.

    Diskussion: Diskussionen jämför resultatet i enkätstudien med tidigare försök från litteraturstudien.

    Metodens för och nackdelar diskuteras. Musikerns och kompositörens roll i ämnet diskuteras och

    framställs med alternativa positioner för framtida bruk. Detta för att skapa förståelse hos musikern/

    kompositören mot resultaten i denna studie och även. Metoddiskussionen fördjupar sig i för och

    nackdelar med studiens metoder.

    Strategic Risk Management: An evaluation of SACF as a strategic risk tool2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Within an organization it is very important to be aware of the risks that arise in the environment, and use effective risk management to maxim-ize the potential profit and minimize the possible threats. SWOT and PEST have been shown to be the most commonly used tools in strategic risk management. Talantsev et al. (2013) have developed a new risk evaluation method for ICT4D projects which in this thesis was called SACF. The purpose of this thesis was to investigate its use on a strategic level and compare it to the already established used method.In this research it was shown that SACF can be used as a tool to create, evaluate and select amongst strategies. It is not a replacement but a complement to the already existing methods. In other words, it can pro-vide the evaluator with additional information not provided by SWOT and PEST.

    Att lokalisera och åtgärda brister i agila projekt: En undersökning med hjälp av kritiska faktorer samt dimensionerna i projekttriangeln2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To only follow agile methodologies for agile software development isn't enough to lead to success in agile projects. The dimensions time, cost and scope in the project management triangle are fundamental requirements to succeed in a project. Within projects there exists many other critical success factors and attributes that affect the result of the project. Those are called critical success factors and combined with a project management triangle they are used in this study as a tool for project improvement in research to find potential improvements for agile project in organizations. This research was carried out as a single case study on a company located in the IT branch. The purpose of the study is to with use of the critical success factors mapping done by Chow and Cao [1] combined with the project management triangle dimensions, research which or what degree of critical factors that were existing in the company’s project management culture. The result was used as a tool to create an improvement plan which purpose was to be applied on existing flaws. The study was performed using qualitative research and data were collected through interviews with the employees. This research shows that potential improvements can easily be found by research projects for critical success factors and the project management triangle dimensions. Combined factors, attributes and dimensions make a complete concept for successful projects. After analyzing and processing the data, a summarize of data were created which showed what factors, attributes and dimensions that were existing and on what degree in the company’s project management culture. This study shows that potential improvements can easily be found by research projects for critical success factors and the project management triangle dimensions. For all missing and low degree attributes an improvement plan was created on purpose to be applied on existing flaws in order to create a higher success factor on future agile projects.

    Digitalisering av systemutvecklingsprocesser: En studie om introducering av digitala processer i en publik IT-organisation2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Digitalization is not a new topic and was first used in the 17th century.  But with the development of information technology the opinions have changed. It is necessary for the organizations to digitize themselves to be competitive. One purpose with digitizing the business area has been to make the process more efficient. Many organizations are digitized, but many of their system development processes are still analog. The aim with this report is therefore to contribute with knowledge for digitalization of system development processes. The goal with this report is that the result will be able for IT-organizations who want to digitize system development processes. Previous research and theories like digitalization, processes, quality and change management are used as a base for this study. The report is using a qualitative approach; data was collected through Mid Sweden University´s library catalog and from Google Scholar. Thereafter was data also collected through interviews with the case company and with external governments. The case study consists of a process mapping on the case company´s system development process. The result describes the difference between system development processes and business what improvement opportunities a system development process has and important factors that governments need to work with in digitalization project are also described. The analyze of the result showed that is important that the laws supports information exchange and cooperation and automated test, continuous delivery and more flexibly work methods are important to being able to digitize system development process. The conclusion was that the preparation and efficiency of the process is the easiest, meanwhile the challenge is to lead the change to the right way. Two important aspects that can help many organizations forward are to work with change management and investigate the method DevOps. For further research it would be possible to perform this study on other governments to investigate which factors they think is important in a digitalization project.

    Cloud Computing: Evaluation, as a platform for Scania Architecture2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Cloud computing has been given a great deal of attention during recent years. Almost all the technology market leaders and leading hosting service providers (like IBM, Microsoft and Verizon) have entered into the Cloud market as Cloud Providers. Cloud computing promises to provide highly available, secure, low cost, agile and highly scalable solution to the consumers.

    Scania is a global company and one of the world’s leading heavy vehicle manufacturers with 35,000+ employees. All the large organizations such as Scania, aim to constantly update themselves with the latest technology in order to meet their business requirements but, these organizations must always be convinced that there is a strong reason(s) to implement new technology.

    This research provides the method and criteria in relation to initiating Cloud computing. A number of Scania’s specific business requirements that it is possible to map to the Cloud are addressed in this thesis. The methodology of research is split in two parts. Firstly, the identification of business cases at Scania and their requirements with the Cloud and Secondly, the evaluation and comparison of the functionalities and capabilities of different vendors. The accumulated data is then compared and suitable vendors, according to those business requirements are suggested.

    This thesis also shares the experience of moving on premise applications to the Cloud. These are Scania specific applications which are currently being hosted in-house. The research also addresses the possibilities of portability between the Cloud providers. Although there is no standardization in relation to Cloud computing, some initiatives such as OpenStack are available and its current position and some application and data migration tools are also discussed.

    The thesis concludes with a general discussion, recommendations in relation to adapting Cloud computing and selecting the Cloud provider. This recommendation applies to every organization including Scania.

This will be achieved by reconstructing the inventory placement in consideration with how frequently the inventories get picked and mass of the inventory. In particular, the literature and the data that is collected from the company´s business system have laid the foundation for the thesis. In general, interviews and observations also contributed to the data collection. To fulfill the aim and to produce arbitrary results, two issues have been developed regarding which attributes that should determine the position of the inventory in the stock house and how to obtain a more effective inventory structure? The authors have jointly produced a result of suggestions for future inventory placement in terms of picking frequency and weight. Initially a situation analysis was conducted to identify known problems with the inventory´s placement and storage systems. The problems that were identified were that the inventory placement has no consideration regarding picking frequency. To determine the most frequent picked inventory an ABC analysis was conducted. All of the inventories were spread out throughout the whole stock house. To take in account, the additional criterion, which was weight, a multi-criteria analysis was performed in combination with the ABC analysis. The results of the combined analysis provided that the basis for drawing up concepts for future inventory placement. The proposal includes optimized inventory placements in different zones of the most frequently picked inventory with weight as an additional criterion.

    An Agile Procurement Model that Facilitates Agile Execution of Projects: A Case Study at Telia Company2016Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Since agile execution of projects has become more frequently used the discovery that the surroundings of the projects are not always compatible has been made. The problematic within the area is traditional accounting restrictions and cost estimation. The purpose with this research is to develop a procurement method that facilitates for agile execution of projects. Previous research proves that the agile principles can be used in a procurement process successfully, but with focus on facilitating on the procurement itself and not on the agile execution. This research includes theories about the agile estimation models and requirement prioritizing methods. The method used to complete this research is design science, which includes six steps to ensure reproducibility and validity. This research resulted in a procurement method that includes three methods and two phases with focus on minimizing the pre-study, with focus on only the most important requirements only. The procurer will then attend the agile execution and both procurer and executer enter the project with the mindset that the initial budget- and time estimation will be increased. Both procurer and executor works together towards the same goal, maximum customer value for minimum cost. The method is tested beside two projects conducted by Telia Company and the test result is that the generated solution reduces the total cost of the project and time to generate project result and facilitates for an agile execution. This research concludes that an agile procurement can facilitate agile execution of project but before agile procurement can be a recommendation more tests are needed.

    Equivalent Circuit Model for Superconductors2003In: IEEE transactions on applied superconductivity (Print), ISSN 1051-8223, E-ISSN 1558-2515, Vol. 13, no 2, p. 1890-1893Article in journal (Refereed)
    Abstract [en]

    We propose an equivalent circuit model that describes the behaviour of a superconductor viewed by an external user, for whom the global variables voltage and current are of interest. It is used in time-continuous simulations and it treats well both the subcritical and supercritical current regime. The model is based on Maxwell's equations, measurement results as well as on the physical structure of a superconducting tape. The incorporated circuit elements have been described in mathematical expressions: a nonlinear resistance and a nonlinear inductance (superconducting core) in parallel with a linear resistance and a linear inductance (silver sheath or by-pass material). The simplicity of the model makes it fast and easy to apply compared to existing numerical models of superconductors, based on finite element methods. Furthermore, it is wide-ranging and may represent a superconductor in many different applications depending on parameter values. Examples of applied voltage and current with non-stationary waveforms on a HTS tape are given. Calculated are the hysteresis losses (due to flux pinning) and resistive losses (due to flux creep and flux flow) in the tape in the range 0.1 to 1.8 Ic.

    A digital 3D signage system and its effect on customer behavior2011In: The International Conference on 3D Imaging (IC3D), IEEE conference proceedings, 2011, article id 6584378Conference paper (Refereed)
    Abstract [en]

    The use of digital signs simplifies distribution. Importantly, it draws more attention than static signs. A way to increase attention is to add an experienced depth. The paper discusses possible alternatives for extending an existing digital signage system to display stereoscopic 3D contents, comparing a decentralized distribution solution and a centralized solution. A functional prototype system was implemented. A new 3D player was developed to render views from different formats. The implemented system was used to study customer behavior when exposed to digital stereoscopic 3D signage in a direct sales situation. The proportion of sales of selected products related to the total number of sold products varied approximately equally before and during tests. An interview study suggests that the sign did not interact with customer decisions: customers were lost at different stages in this series of steps, among others the sign placement.

    "Moving" Prandtl-Ishilinskii operators with compensator in a closed form2006In: Physica. B, Condensed matter, ISSN 0921-4526, E-ISSN 1873-2135, Vol. 372, no 1-2, p. 97-100Article in journal (Refereed)
    Abstract [en]

    The present paper proposes a class of Preisach-like hysteresis models with saturation having the compensator operator in a closed form, where a mean field contribution (moving model or feedback model) is also considered. The paper pays attention to the conditions for which such a "moving" model is well-defined. Moreover, attention is given to the identification procedures requiring a limited amount of data, where some constraints enhance the correspondence of the model to the underlying hysteresis. Examples showing performances of the model in cases of physical interest are provided.

    Basning av alm: En soffa blir till2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats beskriver arbetet med att konstruera och tillverka ensoffa. Arbetet utförs av både snickare och tapetserare men uppsatsen ärbegränsad till att beskriva snickeriarbetet med betoning på momentenmed böjning av trä. Uppsatsen pekar även på viktiga moment därsoffans träkonstruktion är styrd av behoven vid tapetseringen.Trots att böjteknik har en lång och väl dokumenterad historia krävs detegen praktisk erfarenhet för att få full förståelse av har trä beter sig vidbasning och böjning Uppsatsen försöker ge en bild av vägen fram iprojektet med att tillverka en soffa av basad alm.Genom ett soffprojekt gemensamt med en tapetserarstudent tvingaslösningar fram och teoretiska kunskaper vävs samman med praktiskaerfarenheter.Erfarenheterna från soffprojektet visar att det är viktigt med noggrannplanering och samarbete i tidigt skede så att kraven från båda hantverksområdenblir tydliga. Hur tyget fästs och spänns mot trästommenär exempel på tapetserarkunskaper som är viktig att känna till somsnickare.Basning är en teknik som kräver erfarenhet. Litteraturen beskriver tillexempel olika tider i ångkammaren men erfarenheten från detta projektär att det är viktigt att själv testa mycket och få en känsla för hur träbeter sig. Arbetet visar också nyttan av böjband för att träet ska komprimerasistället för att sträckas vilket kan leda till sprickbildning.Detta examensarbete är begränsat i tid. Många intressanta aspekter ochtankar har fått lämnas till framtida undersökningar. Studier av komprimeringav trä, sytematiska tester av basningstider och djupare studierav forskningsrapporter är några exempel på fortsatta undersökningar.

    Interdisciplinary Cooperation And System Modelling As Means To Govern The Anthropocene2015In: Proceedings of the 59th Annual Meeting of the International Society for the Systems Sciences, international society for the systems sciences (ISSS) , 2015Conference paper (Other academic)
    Abstract [en]

    The global development has now come to a critical state where humanity act as a new geological force and it is obvious that there are numerous of environmental problems which arise from the present geosphere-biosphere-anthroposphere interactions which urgently need to be addressed. This paper argues that systems analysis and modelling of environmental systems is one necessary part in successful governing of societies towards sustainability. In the 1960th many observations and data made it evident that the environment in most countries was in a bad state. To get a holistic view of the complex problems and to clarify the relationships of structure and function, systems thinking was applied e.g. modelling, cybernetics, systems analysis, life cycle assessment and energy and material flow analysis. Such tools used collectively, conceptualized as ‘integrated assessment’, can help to communicate fundamental knowledge, and to support decision-making when identifying, developing and implementing precautionary measures and solutions. There are good examples demonstrating the strength of such approaches; Solutions to the ozone depletion by replacing CFC’s with more chemically reactive compounds that are degraded within the troposphere. Acidification of European low buffer soils and lakes, sensitive to acid rain, has decreased due to concerted action on Sulphur emission control in large parts of Europe. The handling and recycling of solid waste has resulted in a considerable reduction of deposits in large parts of the world. This basically natural scientific knowledge has also influenced the development within e.g. economy and jurisprudence and today ecological economy and environmental law assume ecological systems as fundamental.

    The complexity of ecosystems and environmental issues can only be understood by use of advanced scientific tools such as modelling as a base for establishing interdisciplinary co-operation. Each component of such models will of course be an approximation, but validation and verification of the models will serve to make them useful. An ongoing research project at Mid Sweden University aims at building a complete carbon and energy balance model of an entire Swedish region, based on the Danish Samsø-model. Such models will make it possible to refer to a robust scientific base, thereby making it easier to argue for appropriate measures and actions. At the same time it will be clear what data these actions rest upon thereby making it easier to identify possible errors or limitations.

    Systems analysis and subsequent modes are constructs. According to systems theory and model development they are strategies as the best representations of nature, we can make. At the same time it must be assured, that a continuous adaptation and improvement in a studied area is possible - i.e. that model outcomes are matched with phenomenological observations and that empirical work also is carried out. Model development can therefore be characterized as a dynamic and iterative process.

    Governance in the Anthropocene must be based on an understanding of the problem picture at hand, and learning how to appropriately address increasingly complex issues. For identifying potential solutions and consequences of policy implementation, systems modelling on relevant levels will be one necessary tool. The current project developing an environmental regional model, illustrates how modelling can provide decision support for the county of Jämtland regarding management of energy resources and planning of future infrastructure, as well as serving regional and national information purposes.

    Digital mognad i teori och praktik: en fallstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digital maturity is frequently discussed in organizations and research but is not always defined. There is also limited information about digital maturity in different industries. The purpose of this study was to compare a technical consulting firm's view of digital maturity compared to current research literature. The study consists of two parts: a literature study and a case study at Sweco civil in Sundsvall. The literature study showed that five factors are recurring: strategy, culture, technology, leadership and obstacles. This study confirms similarities with previous research findings regarding strategy, culture, barriers and technology described in similar ways at Sweco. The difference points to the fact that the company focuses more on technology and less on leadership than the literature does. In the literature, the factors are not always structured in a staircase that describes the relationship between levels. However, Sweco has a staircase that goes from standardization to integration and automation and finally transformation of business models. In all levels, the absence of leadership: goals, vision, and governance is an obstacle. To achieve standardization, the absence of a common industry standard was an obstacle and a negative attitude to new technology among employees. The middle level integration has barriers in the form of lack of coordination. The automation level experiences obstacles in the form of a lack of technical competence. The highest level of innovation has barriers in the form of lack of interest for innovation among employees, customers and partners. There is also a shortage of venture capital.

    Business models for Internet of Things: A literature review on similarities and key areas2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The area of business models for the Internet of Things and how to approach modelling them is relatively unexplored. Therefore this study researches how others have previously approached the area through a literature analysis. The articles showed several different ways of describing business models for IoT, some of these where based around old and well known tools such as Business model canvas. While other approaches where based on creating entirely new models based on modern technology. One of these models is based around blockchain technology, the last main approach is to innovate the tool used to describe business models in order to be able to manage the change in actors. After analysing the different approaches by comparing them to either their standard model or seeing what the key part of the model was, it became obvious that business models for IoT have certain areas that need to be taken into account. These areas are not commonly seen in previous tools used to describe business models. One of these areas is increased collaboration as a consequence of increased number of participants in the creation of an IoT service or product. The other area is increased focus on IT knowledge, partners and therefore also increased cost. This is a consequence of the increased amount of technology needed. These areas in particular the increased collaboration strongly affects the business model and therefore is one of the main reasons for the business model innovation in the IoT market.

    Kritiska framgångsfaktorer vid införande av GDPR inom bank och finans2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    On May 25, 2018, the Directive, 95/46/EC, is superseded by the General Data Protection Regulation (GDPR), (EU) 2016/679. Companies and organizations will have to revise routines, restructure organizations' processes and rebuild IT systems. The purpose of this study is to identify the critical success factors for implementing GDPR in the Swedish banking and finance sector. The study carried out a literature study as a foundation for the qualitative interviews with which empirical was gathered. Subjects for interviews was data protection officers (DPO) at four banks, as well as the Swedish Data Protection Authority and Forum för dataskydd, a national forum for DPO:s. The study's results showed a number of significant success factors for implementation processes. Based on these success factors, three were identified as critical to the implementation of GDPR from a computer science perspective: data governance, privacy-by-design, and documentation.
