    "En vän i fickan": Ett organisationshjälpmedel i vardagen2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att ha kontroll över och strukturera upp sin vardag kan vara svårt för många och speciellt föräldre. Har eller får man även en kognitiv nedsättning blir detta i stort sett omöjligt utan hjälpmedel.Målet med detta arbete var att i samarbete med Doro, ta fram ett elektroniskt hjälpmedelför att underlätta vardagen för äldre med funktionsnedsättning och personer med kognitivanedsättningar. Grunden till arbetet blev en stor förundersökning där användarnas behov ochkrav utforskades. De största behoven som sågs hos målgruppen under förstudierna var att kunnakontakta närstående och att strukturera upp och klara av vardagen. För att klara detta användesmobiltelefoner, scheman, listor, kalendrar, larm, påminnelser samt tids- och ekonomihjälpmedeli analog eller digital form. Några av de krav som ställdes på produkten var att den skullevara mobil, anpassningsbar, ge trygghet och inte sticka ut. Utifrån förstudierna togs ett konceptfram med ett applikationssystem för att lösa behoven, tillsammans med en fysisk utformningav en mobil produkt. Genom användartester med så väl målgruppen som experter testades ochutvärderades konceptet och utvecklades i flera steg i samarbete med dessa. Resultatet av arbetetvar uppbyggnaden av ett interaktionssystem för applikationer, speciellt anpassat för målgruppensamt en fysisk modell av en smartphone. Det största fokuset lades vid det interaktiva systemeteftersom det ansågs att det var här de största problemen låg i dag.

    Nation Branding: Profilering av varumärket Sverige med ett webbperspektiv2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Nation branding innebär att profilera och varumärka ett land. Här ingår att kommunicera immateriella värden såsom det upplevelsebaserade, och att visa på det unika med landet. Globaliseringen har skapat förändringar som gör att Sverige inte längre klarar sig på att vara välkända enbart i Europa. Ökad handel med områden där Sverige är relativt okänt betyder att Sverige måste kommunicera sitt varumärke på ett nytt sätt. Syftet med studien är att undersöka hur kommunikationen för profileringen av Sveriges nation branding ser ut, med fokus på webben som kanal. Utifrån teorier om globalisering, pr, varumärkning och användbarhet på webben, har vi utfört studien i två delar. Inledningsvis genom kvalitativa intervjuer med utvalda representanter för Sveriges nation branding, därefter genom en kvalitativ innehållsanalys på deras webbsidor. Enligt resultatet drar vi slutsatserna att grunden för en enhetlig profilering av Sverigebilden i utlandet sker utifrån en gemensamt framtagen varumärkesplattform och Sverigeportalen Sweden.se. Målgruppen definieras enligt empirin som en progressiv grupp i utlandet, och webben är en viktig kanal för Sveriges nation branding. Regelbundna studier genomförs också av de ansvariga organisationerna för att utvärdera hur väl den önskade bilden av Sverige når ut till målgruppen. Nation branding för varumärket Sverige tycks mer handla om Sverige som en mental plats än en fysisk plats. Detta skulle kunna vara ett sätt för landet att differentiera sig. Avslutningsvis väljer vi att inkludera ett kort kapitel om fortsatt forskning, där vi ger förslag på vidare studier kring några av de ämnen och företeelser som framkommit i studien.

    Det går inte att bullshitta sig fram: En kvalitativ studie om relationsbyggande genom sociala medier2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vår studie tar vid de utmaningar som organisationer i nuläget ställs inför då de ämnar bygga relationer med befintliga och potentiella kunder i de sociala medierna. Studien tar upp teorier kring asymmetrisk och symmetrisk tvåvägskommunikation, riskhantering, etikens roll i PR, organisationskommunikation, marknadskommunikation, meningsskapande, dialog samt relationsbyggande kommunikation.

    Undersökningen grundar sig på åtta djuplodat semistrukturerade samtalsintervjuer med svenska PR-aktörer med digital kommunikation som främsta inriktning. PR-aktörerna valdes utefter deras lämplighet att besvara studiens syfte.

    Resultatet visar att sociala medier påverkat förutsättningarna för organisationers relationsbyggande kommunikation. Kommunikationen sker i större utsträckning på mottagarens villkor, vilket medfört att organisationer måste vara lyssnande och anpassa sig utifrån de förutsättningar som sociala medier medför. Publiken blir mer svårengagerad och kräver högre relevans, vilket innebär att relationsbyggande kommunikation på sociala medier måste utgå från gemensamma intressen och ömsesidiga fördelar.

    Samtidigt blir etikens roll i PR allt viktigare i och med den transparens som sociala medier medför. Organisationer exponeras på sociala medier vare sig de är närvarande eller inte och det finns inga tecken på att de sociala mediernas utbredning och inflytande kommer att stanna av.

    Studien kom även fram till att sociala medier tvingat företag att decentralisera sin internkommunikation för att uppnå bästa möjliga resultat i sin externkommunikation. Det finns dock en ovisshet i hur PR-aktiviteter mäts och bör mätas för att kunna påvisa dels ekonomisk vinning men även relationsskapande med publiken.

    Concept for hybrid random/dynamic radio resource management1998In: Proceedings of the 1998 9th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC '98. Part 3; Boston, MA, USA; 8 Sept. - 11 Sept. 1998. Vol. 1, IEEE , 1998, p. 424-428Conference paper (Refereed)
    Abstract [en]

    Third generation mobile communication systems will allow many different services with varying demands on data rate and delay. For those systems, the fixed radio resource management (RRM) techniques used in today's low rate systems will not be appropriate to ensure efficient utilization of the radio spectrum. Dynamic RRM is necessary in order to cope with the large variations in data rate. We study the bunch concept which is a hybrid between random and dynamic RRM. Within a small synchronized cluster (bunch) we use dynamic radio resource allocation combined with SIR-based power control and between the bunches we use time/frequency hopping to average the interference. We propose an improved RRM algorithm and evaluate the performance of the bunch concept for a Manhattan scenario with mixed traffic. The performance is improved while the computational complexity is reduced compared to our previously published results for the bunch concept. We also show that the performance of a single bunch system is close to the theoretical upper bound.

    Maintaining high Capacity for Centralized DCA with Limited Measurements and Signaling1999In: Proceedings of the 1999 10th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC '99, Osaka, Japan, Sept 12 - 15, 1999, IEEE , 1999Conference paper (Refereed)
    Abstract [en]

    Centralized dynamic channel allocation strategies can, in theory, achieve very high capacity in terms of achievable load at a certain quality level. Unfortunately, these strategies have often been considered non-feasible in practice due to the massive amount of measurements and signaling typically required. In this paper we evaluate some methods to maintain high performance while drastically reducing the measurement and signaling requirements. Our DCA algorithm is based on measurements of the link gain matrix. We show that for a microcellular Manhattan environment, only the gains from the three strongest beacons have to be measured and signaled by each mobile in order to achieve almost the same capacity as an ideal system where all beacons can be measured

    Performance of Mobile Station Location Methods in a Manhattan Microcellular Environment2001In: 3GW 2001, San Fransisco, June 2001, 2001Conference paper (Refereed)
    Abstract [en]

    Positioning of users in cellular systems is an area attracting large interest and the number of applications for the location information is growing rapidly. Large-scale deployment of such applications will require methods for positioning that are simple enough to be used in mobile phones. In this paper, we evaluate the location accuracy for some different algorithms in a microcellular environment. We propose some simple but quite accurate methods and compare them with commonly known methods. Our results show that in the studied environment, all our proposed algorithms can at least manage the US E911 phase II requirements of positioning emergency calls within 125 m, 67 percent of the time.

    Ettabilder: - så väljer redaktionerna2008Student paper other, 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Uppsatsens titel: Ettabilder – så väljer redaktionerna

    Ämne/kurs: C-uppsats, medie- och kommunikationsvetenskap,

    15 poäng

    Författare: Linn Bergbrant och Mikaela Lindholm

    Handledare: Elisabet Ljungberg

    Syfte: Syftet med studien är att undersöka hur svenska

    morgontidningars redaktioner väljer ettabilder.

    Metod: I studien användes en kvantitativ metod. En

    enkätundersökning skickades ut till sextio av de största

    svenska morgontidningarnas redaktioner. Frågorna som

    ställdes till respondenterna handlade om vilken uppgift

    redaktionerna anser att ettabilden har, vilka sorts

    ettabilder som väljs, vilket geografiskt ursprung de har och

    vem som syns på bilderna. Enkäten hade även frågor om

    hur redaktionerna går tillväga när de väljer ettabilder och

    hur viktigt de anser att valet är.

    Teoretiska perspektiv: Studiens teoretiska referensram är uppbyggt kring

    teorier om tidningens förstasida, bildkommunikation, bildurval,nyhetsvärdering

    och relationen mellan text och bild i tidningen.

    Slutsatser: Studiens resultat visar att redaktionerna anser att ettabilden

    är väldigt viktig och att dess främsta uppgift på förstasidan

    är att locka till läsning, väcka uppmärksamhet och beröra

    läsarna. Lokala bilder som visar icke-offentliga personer

    prioriteras högt. När det gäller det ämne som ettabilden

    skildrar pekar resultaten på att det främst finns två

    vanligt förekommande alternativ. Dessa är att antingen

    välja en bild som skildrar en viktig nyhetshändelse eller att

    välja en estetiskt tilltalande eller lättsam featurebild.

    Grön identitet.: Konsten att kommunicera klimatsmart.2011Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    One of the top issues on the world´s agenda is global warming. To meet the challenge in finding non-polluting alternatives to coal, gas and oil, wood as the raw material has become an interesting option. The aim with the study has been to examine how various organizations in the biorefinery business communicate both their environmentally friendly activities as well as their products. Is this green marketing anchored in the overall identity and in that case how? How is the green profile communicated externally? Which are the main arguments for being green? These questions are answered by qualitative interviews as the method.

    The theoretical base is focused on identity, profile and image. It is intimately connected to research in Corporate Social Responsibility (CSR) which is to one part focused on the environmental aspect. Ethics and theories about publics is also part of the theory basis.

    The result shows an awareness of how to market one selves as a green company. These four companies have reached different levels of maturity in their green marketing. As the examined companies are two municipal energy companies and two profit based industries means different starting positions, background and reasons to communicate their green identities. An overall argument in all studied companies is that the sustainability argument is crucial both within the operations as well as the communications.

    Ideologi eller marknad?: En kvalitativ studie om hur de ideologiska värderingarna närvarar, i de svenska riksdagspartiernas politiska tv-reklam, under valet 2010.2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den strategiska politiska kommunikationen och valkampanjerna har blivit allt viktigare (Nord & Strömbäck, 2003, s.47). I Samband med detta har det marknadsorienterade partiet upptäckts framträda, ett parti som inte längre är knutet till sina ideologiska värderingar utan strävar efter att tillfredställa marknadens önskningar och behov (Strömbäck, 2009, s.228; Lilleker & Lees- Marshment, 2005, s. 1).

    Syftet med denna studie är att, utifrån teorin om politikens marknadsorientering, undersöka hur de svenska riksdagspartiernas ideologiska värderingar och aktuella sakfrågor är närvarade i de politiska tv-reklamerna från valrörelsen 2010. Vi undersöker hur partiernas ideologiska värderingar kommer till uttryck och i vilken utsträckning reklamfilmerna fokuserar på ideologiska värderingar respektive aktuella sakfrågor. Vi studerar även hur kopplingen ser ut mellan de aktuella sakfrågor som lyfts fram och de ideologiska värderingarna. Utifrån detta resultat kan vi vidare se tendenser på produkt-, sälj- eller marknadsorientering hos partierna.

    Detta utförs med kvalitativa textanalyser på riksdagspartiernas partiprogram, principprogram eller idéprogram följt av semiotiska analyser, med fokus på denotation och konnotation, på samtliga politiska tv-reklamer från valet 2010. Studien visar att Centerpartiet, Folkpartiet, Moderaterna, Socialdemokraterna, Sverigedemokraterna och Vänsterpartiet visar tendenser på säljorientering. Kristdemokraterna pekar åt det produktorienterade hållet. Miljöpartiet är det svårt att dra en slutsats om på grund av den aktuella miljö-/klimatfrågan, men partiet befinner sig inom ramen för produkt- och säljorientering. Studiens resultat styrker Strömbäcks menande om att politisk säljorientering troligen är det som kommer dominera inom svensk politik (Strömbäck, 2010, s.62).

    Välkommen in i hetluften: En kvalitativ studie av Utrikesdepartementets kriskommunikation genom UDbloggen2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med studien är att undersöka hur Utrikesdepartementet förhåller sig till UDbloggen i samband med kriskommunikation.

     

    Teori: Teorier som används i studien utgår från tre övergripande teoretiska områden: strategisk kommunikation, kriskommunikation samt sociala medier, med tyngdpunkt på företagsbloggen.

     

    Metod och material: Sex stycken kvalitativa samtalsintervjuer har genomförts med medarbetare från tre enheter på Utrikesdepartementet i Stockholm, samt vid den svenska ambassaden i Kairo. Detta för att dessa ingår i ett samarbete då det kommer till krishantering och kriskommunikation. En övergripande kvalitativ innehållsanalys har också genomförts av 20 utvalda blogginlägg från UDbloggen.

     

    Huvudresultat: Studiens resultat visar att UD anser att en kris präglas av informationsbrist hos allmänheten och att kommunikation spelar en stor roll i dess krisarbete. Därför var man positiv till UDbloggen och dess förmåga att snabbt nå ut med information för att fylla det informationsbehov som uppstår vid en kris. Däremot har UD inte kommit lika långt i planeringen av kriskommunikationen då det inte finns någon kommunikationsplan med mål, definierade målgrupper eller någon budskapsstrategi. Ett strategiskt tankesätt kunde däremot urskiljas då studiens respondenter har en gemensam bild om dessa olika delar, vilket också bekräftades genom innehållsanalysen. Men detta innebär inte att denna bild ser ut på samma sätt inom hela departementet. Innehållet på UDbloggen är anpassat efter målgruppen och både öppenhet, snabbhet och tydlighet var distinkta drag i bloggen. UD såg också interaktion som viktig vid krissituationer, ändå finns en skild mening mellan PIK (press, information- och kommunikationsenheten) och studiens övriga respondenter kring bloggens för- och nackdelar. Dels kring att bloggens interaktiva karaktärsdrag kräver mycket resurser, vilket PIK anser bör vara prioriterat, medan det finns en osäkerhet bland övriga kring var resurserna ska läggas vid en kris.

    Strong Support for News Media: Attitudes Towards News on Old and New Platforms2012In: Media International Australia, ISSN 1329-878X, no 144, p. 118-126Article in journal (Refereed)
    Abstract [en]

     The aim of this article is to analyse attitudes towards news on old and new platforms. Our study used two types of independent variable: generation, which - along with age - is one of the most important factors explaining news media practices; and news consumption, which is strongly related to attitudes. We utilised a national mail survey of 3000 people in the Swedish population (aged 16-85) to conduct the study. The response rate in the 2010 study was a little over 60 per cent, and the survey gives a significant picture of news attitudes in the population. The findings generally show a strong degree of support for traditional news media such as television and printed newspapers. However, this support is far stronger among the older generations than the younger - who, to a larger extent, express support for other forms of news distribution, in particular the internet and social media networks.

    Sociala medier i Kina: En studie av användningen av sociala medier i en diktatur2010Report (Other academic)
    Abstract [sv]

    De sociala mediernas genomslag har knappast passerat obemärkt under de senaste årens demokrati- och mediedebatt. Förändringarna på mediemarknaden och explosionen av kommunikationskanaler förändrar människors medieanvändning inte bara i demokratiska länder. Även i diktaturer förändrar Internet medborgarnas möjlihgeter att kommunicera och at ta del av information.I takt med att valmöjligheterna för mediekonsumter ökat har också intresset för traditionella forskningsfrågor om sambandet mellan människors personliga motiv och preferenser å ena sidan, och deras medieanvändning å den andra, vuxit. I denna rapport analyserar Marie Bergström och Helene Nyberg användningen av sociala medier bland universitetsstudenter i Kina. De undersöker sambandet mellan studenternas användning av sociala medier och deras sociala aktivitet i "verkliga livet", studenternas motiv för användningenen av sociala medier, samt i vilken utsträckning politiskt intresse och traditionell mediekonsumtion a relaterat till användning av sociala medier. Rapporten belyser också relevansen av traditionella teorier inom medie- och kommunikationsvetenskapen - såsom Uses and gratifications theory - för att förstå människors användning av nya medier.För rapportens innehåll och slutsatser svarar författarna själva.

    Sociala medier i Kina: En studie om användningen av sociala medier i en diktatur2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student’s being socially active offline, tend to use the media to a greater extent than those less active.

    Abstract [en]

    A printed circuit board transformer comprises at least one primary winding and one secondary winding, each in the form of at least one layer of turns inside or at the surface of a printed circuit board. The transformer is designed for a step-up/down-operation. Each of the two layers (10, 11) has an elongated winding element (12, 13, 13′) substantially following an elongated winding element of the other layer while being in an overlapping relationship therewith as seen perpendicularly to said printed circuit board over substantially the entire extension of said winding elements. A second (11) of the layers belonging to the secondary winding has a fewer number of turns than the first (10) of said layers belonging to said primary winding.

    Monte Carlo simulation of vertical MESFETs in 2H, 4H and 6H-SiC2001In: Diamond and related materials, ISSN 0925-9635, E-ISSN 1879-0062, Vol. 10, no 3-7, p. 1283-1286Article in journal (Refereed)
    Abstract [en]

    The 4H-SiC static induction transistor (SIT) is a very competitive device for high frequency and high power applications (3-6 GHz range). The large breakdown voltage and the high thermal conductivity of 4H-SiC allow transistors with extremely high current density at high voltages. The SIT transistor shows better output power capabilities but the unity current-gain frequency is lower compared to a MESFET device. In this work we show, using a very accurate numerical model, that a compromise between the features given by the SIT structure and the ordinary MESFET structure can be obtained using the vertical MESFET structure. The device dimension has been selected very aggressively to demonstrate the performance of an optimized technology. We also present results from drift-diffusion simulations of devices, using transport parameters obtained from the Monte Carlo simulation. The simulations indicate that 2H-SiC is superior to both 4H and 6H-SiC for vertical devices. For lateral devices, 2H-SiC is slightly faster compared to an identical 4H-SiC device

    Simulation of a low atmospheric-noise modified four-quadrant position sensitive detector2001In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 466, no 1, p. 183-187Article in journal (Refereed)
    Abstract [en]

    A modified four-quadrant position sensitive detector (PSD) is developed. This structure is less sensitive to atmospheric turbulence that is a major drawback with the traditional four-quadrant detector. The inter-electrode resistance is as high as for the four-quadrant detector, which is an advantage compared to the lateral effect PSD. The linearity for the modified four-quadrant detector is good in the whole active range of sensing. The structures are limited to small sensing areas with well focused beams and are suitable for use in detectors up to 1 mm in size.

    Calculation of lattice heating in SiC RF power devices2004In: Solid-State Electronics, ISSN 0038-1101, E-ISSN 1879-2405, Vol. 48, no 12, p. 1721-1725Article in journal (Refereed)
    Abstract [en]

    Silicon carbide MESFET devices are suitable for high-speed and high-power applications. In this paper we are studying thermal effects in 4H-SiC RF power devices. The simulations are based on a combination of 2D device simulations for the electrical transport, and 3D thermal simulations for the lattice heating. We show that the method gives good accuracy, efficiency, flexibility and capacity dealing with tasks, where a 2D coupled electrical-thermal simulation is not sufficient. We also present an improvement of Roschke and Schwierz mobility model, based on Monte Carlo simulations for the temperature dependencies of the mobility parameters beta and v(sat).

    Abstract [en]

    Both unipolar and injection SiC devices can be used for high voltage switching applications; it is not determined, however, for which applications one approach is preferred over the other. In this paper, simulation studies are used to compare the suitability of unipolar devices, in this case a JFET (Junction Field Effect Transistor) against an equivalent FCD (Field Controlled Diode) configuration up to very high voltages. The calculations are performed in a finite element approach, with commercial drift-diffusion software. Numerous drift layers have been simulated in a Monte-Carlo approach to ensure that the optimal design of the drift layers for different breakdown is used. In a static case, purely conductive losses in the drift layer in both unipolar and injection configuration are compared. Additionally the total losses are studied and compared in switched applications for different switching frequencies and current levels.

    Optimization of 2H, 4H and 6H-SiC high-speed vertical MESFETs2002In: Diamond and related materials, ISSN 0925-9635, E-ISSN 1879-0062, Vol. 11, no 3-6, p. 1254-1257Article in journal (Refereed)
    Abstract [en]

    Silicon carbide vertical MESFET devices are well suited for high speed and high power electronic devices. In this work we have optimized the geometry of vertical MESFETs for microwave applications, using iterative two-dimensional simulations. Relevant parasitics are included in the simulations to investigate the performance of realistic devices. The state of the art device has f(T)=7 GHz and we show that vertical MESFETs fabricated with traditional technology are totally limited by parasitics. Two different approaches to reduce the parasitics in the vertical MESFET are proposed where f(T) increases significantly.

    Abstract [en]

    Silicon carbide MESFET devices are well suited for high speed, high power and high temperature electronics due to high saturation velocity, high critical electrical field, good thermal conductivity and large band-gap. Optimization of a high performance device demands a substantial number of numerical simulations, where several different design parameters have to be investigated thoroughly. In this work, we optimize the geometry of lateral MESFETs for maximal unity current-gain frequency (fT) using iterative 2-dimensional simulations. We also present a comparison of performance for individually optimized devices, realized with lithographic resolutions ranging from 0.2 to 2 μm in different SiC polytypes.

    The power of using automatic device optimization, based on iterative device simulation, in design of high-performance devices2004In: Solid-State Electronics, ISSN 0038-1101, E-ISSN 1879-2405, Vol. 48, no 10-11, p. 1721-1725Article in journal (Refereed)
    Abstract [en]

    An automatic optimization tool for semiconductor devices based on iterative device simulations is developed. The tool is used for optimization of different kinds of semiconductor devices using various performance measures. High performance optimization algorithms, both local and global, are used to achieve an efficient design in shortest possible time. In this paper the effects of different optimization algorithms, performance measures, and number of variables in the optimization are studied. Both the computational efficiency and the devices achieved with different performance measures are studied. We give a demonstration of the usefulness of this method in a comparison between different device topologies, which have been optimized for best performance.

    Abstract [en]

    Device design is a time consuming work, where the influence of many design parameters has to be investigated carefully. In advanced devices optimal performance is often achieved taking multiple trade-off into consideration, and manual device optimization is often insufficient. In this paper we present the feasibility of using device optimization for design on electronic devices. An optimization tool is developed, which runs device simulations and automatically changes the design parameters, searching for optimal performance according to a specified performance measure. This has been shown to be a very time and cost efficient way for device design, as the search for optimal performance is fuily automatic working in a systematic way 24 hours 7 days a week. From an industrial point of view this is very important as it can reduce the evaluation and optimization cost for new devices considerably. It is impossible to give a fair comparison between different devices unless these are designed to give optimal performance. We give a demonstration of the usefulness of this method in a comparison between different device topologies which individually have been optimized for best performance.

    A full band Monte Carlo (MC) study of the high frequency performance of a 4H-SiC Short channel vertical MESFET is presented. The MC model used is based on data from a full potential band structure calculation using the local density approximation to the density functional theory. The MC results have been compared with simulations using state of the art drift-diffusion and hydrodynamic transport models. Transport parameters such as mobility, saturation velocity and energy relaxation time are extracted from MC simulations

    Simulation of anisotropic Breakdown in 4H-SiC Diodes2000In: IEEE Workshop on Computers in Power Electronics: COMPEL 2000, IEEE , 2000, p. 118-120Conference paper (Refereed)
    Abstract [en]

    The breakdown characteristics of two-dimensional 4H-SiC diode structures have been studied using an anisotropic drift-diffusion model. The degree of anisotropy was estimated from recent full band Monte Carlo simulations. Identical diode structures have previously been used in the literature to measure the hole impact ionization coefficients of 4H-SiC. The reported measurements from different research groups show large differences in the impact ionization coefficients. Our numerical simulations show that the differences in these measurements can be explained by the difference in device geometry used by the research teams if one considers an anisotropic impact ionization process. This indicates that it is very important to consider anisotropic impact ionization in design and characterization of 4H-SiC power devices.

    An empirical study of IS architectures in French SMEs: Integration approaches2012In: European Journal of Information Systems, ISSN 0960-085X, E-ISSN 1476-9344, Vol. 21, no 3, p. 287-302Article in journal (Refereed)
    Abstract [en]

    This paper, based on a cross-sectional empirical study of information system (IS) architectures within 143 small to medium enterprises (SMEs) in France, reports findings on how SMEs architect to achieve IS integration and interoperability. This research provides an empirically derived taxonomy of enterprise architectural variants of the types often described in the literature for large firms. This study finds indications that for SMEs the immediate goal of interoperability prevailed over fuller and more formal system integration. The most common means for approaching enterprise architecture and any form of integration is via the construction of software bridges and interfaces. Partially standardized architectures based on Enterprise Systems (ERP) are the next most common type. Hybrid architectures- mixed Enterprise Applications Integration and ERP- are the third most common. The contribution of this paper lies not in the identification of the three types but resides (1) in the description of their distribution in SMEs; (2) in the absence of other integration/interoperability types in this population; and (3) most importantly in the interpretation of the organizational and historical rationale explaining the emergence of these types in this organizational context. © 2012 Operational Research Society Ltd.

    Risk Assessment of New Pricing Strategies in the District Heating Market: A Case Study at Sundsvall Energi AB2010In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 38, no 5, p. 2171-2178Article in journal (Refereed)
    Abstract [en]

    The price structure of district heating has been no major scientific issue for the last decades in energy related research. However, today trends in district heating pricing tend to move towards a more customer oriented approach with fixed prices under a longer period, leading to a more complex price structure. If a district heating supplier offers district heating with fixed prices in order to compete with similar electricity offers, the financial risk of the fixed price product is significantly higher than the risk of an ordinary variable cost offer. In contrary to an electricity seller, the district heating company can not transfer all of the risk of fixed prices offer to the financial market, instead the company is thrown upon its own ability to handle the risk by, e.g., hedging its own energy purchase. However, all uncertainties can not be coped with in this manner. Thus, there is a need for a methodology that can be used to estimate the financial risk of different price structures and to value different opportunities to reduce the risk. In this article we propose a methodology, implemented in a prototype software, to evaluate the risk associated with new price structures in district heating.

    Inventering och kartläggning av behov för personer med psykiska funktionshinder.: Resultat för Härnösands kommun2007Report (Other academic)
    Abstract [sv]

    Enligt 5a § SoL ska socialnämnden göra sig väl förtrogen med levnadsförhållanden i kommunen för människor med psykiska och fysiska funktionshinder samt i sin uppsökande verksamhet upplysa om socialtjänstens verksamhet. En inventering och kartläggningsprojektet infördes under 2005 i Härnösands kommun i samarbete med FoU Västernorrland och Landstingets sjukvårdsdistrikt. Syftet med kartläggningen har varit att öka möjligheten att kunna planera bra insatser till personer med psykiska funktionshinder. Avsikten är att beskriva de olika behov som finns hos de individer och grupper som psykiatrireformen riktade sig till, men även behov som andra med psykiska funktionshinder har idag. Projektet skulle därför också försöka kartlägga behoven bland individer som riskerar att bli allvarligt psykiskt funktionshindrade och bland dem som har börjat en återhämtningsprocess. Resultaten bekräftade många behov som är väl dokumenterad, att personer med psykiska funktionshinder leva i samhället men har få möjligheter att aktivt delta i samhällslivet runt omkring dem. Resultaten pekade också på nya behov som har kommit fram och som kanske kan vara en ledtråd till nya möjligheter som kommun måste ta hänsyn till.

    Experimental identification of the optical phonon of CoSi2 in the infrared1995In: Applied Surface Science, ISSN 0169-4332, E-ISSN 1873-5584, Vol. 91, no 1-4, p. 30-33Article in journal (Refereed)
    Abstract [en]

    A weak but clear optical structure was detected at 329 cm−1 by both reflectance and transmittance measurements in the far infrared on a 430 Å film of CoSi2 grown on Si(100). This is the first observation of the IR vibrational mode of the cubic structure of CoSi2 and the result is in very good agreement with theoretical calculations. In order to characterize the sample, the reflectance was extended up to 5.2 × 104 cm−1 and the refractive index was also directly obtained in a more limited spectral range by spectroscopic ellipsometry. The IR structure was then quantitatively analyzed by means of a fit procedure, obtaining the values of ω0 = 327 cm−1 for the phonon energy, of γ = 10.5 cm−1 for the damping parameter and of 0.006 electronic charges for the screened effective ionic charge.

    Syfte

    Syftet med studie är att ta reda på hur medarbetare från tre olika arbetsplatser inom Spendrups uppfattar kommunikationen kring förändringen på Vårby bryggeri.

    Frågeställningar

    Hur den dagliga kommunikationen mellan chefer och medarbetare upplevs av medarbetarna. Hur medarbetarna vill att kommunikationen mellan chefer och medarbetare ska fungera. Hur medarbetarna upplever kommunikationen kring nedläggningen.

    Metod

    Studien har gjorts i form av nio fokusgrupper bestående av 3-5 deltagare från Spendrups medarbetare.

    Resultat

    I studien framgår det att Spendrups förändringskommunikation fungerar bra initialt men saknar uppföljning. Dessutom vill medarbetarna i regel ha en mer tillgänglig chef. De tillfrågade medarbetarna anser att kommunikationen i organisationen oftast sker muntligt, och de vill ha det så, men att informationen inte är tillräcklig. Detta har resulterat i ryktesspridning och en del oro, främst på bryggerierna i Vårby och Hällefors.

    Nyckelord

    Förändringskommunikation, intern kriskommunikation, medarbetarskap, ryktesspridning, kommunikationsprocesser, förändringsprocesser.

    A first step towards general quality requirements for e-records.2006In: Advances in information systems development: bridging the gap between academia & industry.: Proceedings of the Fourteenth International Conference on Information Systems Development: Methods and Tools, Theory and Practice, London: Springer , 2006, , p. 1052p. 745-756Conference paper (Other academic)
    Abstract [en]

    Medical journals, police reports, and company registrations are all example of records, recorded information. Many organizations make a change from paper based records to electronic records. One key characteristic of records is that they are going to be preserved for long time, some forever. Both the Swedish Agency for Public Management and the Swedish Emergency Management Agency have identified preservation of electronic records as a problem, needed a quick solution. A record should be able to serve as evidence over actions and transactions, and should support accountability. For this must records be reliable and authentic, i.e. be trustworthy. Questions of immediate interest are how should information systems be designed and developed to maintain trustworthiness in electronic records? And what quality requirements are needed for both electronic records, and for information systems? Non functional requirements are about quality issues for future systems and software. In this research are the interest quality requirements, a type of non functional requirements, for electronic records. The aim of this research was to study a development project of an electronic record management system/electronic archive system, in order to identify quality requirements needed for maintaining trustworthiness in electronic records over time. A seven month case study has been performed, following a development project at Swedish Companies Registration Office, a development project of an electronic archive system solution. The collected empirical material resulted in a set of six different quality requirements for maintaining trustworthiness in electronic records. The identified quality requirements are a first step towards identifying general quality requirements for electronic records. Some of the quality requirements are valid both for the electronic record it self, and for the electronic archive system.
