Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

"Ya know, I don't mind being labeled a crackhead." : En semiotisk analys av hur tv-spelet Grand Theft Auto V skildrar hudfärg, klass och kön

The purpose of this thesis is to examine the representation of race, social class and gender in the 2013 video game Grand Theft Auto V. Postcolonial theory, including terms such as cultural hegemony, whiteness and Michel Foucaults definition of power, has served as the basis for the analysis. The postcolonial theory has been combined with class theory and gender theory for an intersectional analysis. Semiotic analysis has been used as the method in the thesis, and a total of nine story missions ? three for each protagonist in the game ? have constituted the material.

Aktivisten- egoist, karriärist eller eldsjäl? En studie rörande motiven bakom frivilligt engagemang

When it comes to investigating the motives behind activism, the members of political study have a lot to say. I aimed to critiqually rewiev this in my thesis. I asked the question ?What do the actor themselves claim lay behin their decision to become motivated?? To highlight this complex dilemma, I sought to discuss new social movement theory by comparing it to reality. This includes a literate examination on contemporary political science approaches, and a study of two organisations in the south of Sweden, choosen not to despise any excisting theory, but to give it a sense of reality.

Från pluralism till professionalisering? En textanalys av Karlskrona kommuns hållbarhetsarbete

The purpose of this thesis is to shed light on a present trend of professionalization in Swedish local environmental politics, which have recently seen a decline in active participation of the citizens in favor of an increased governmental regulation. With the aim to closer investigate this relatively new phenomenon, the paper is a qualitative single case-study of environmental policies in the Swedish municipality of Karlskrona. In this case, the municipality is obviously balancing between regarding the interests of the national level and the interests of its own citizens at the same time. This motivates the use of system-theory, and relates to the classical political paradox between participation and efficiency which is also a present theme in the paper.This text-analysis based on interviews with personnel and documents from the municipality shows a visible trend of professionalization in the local politics of the municipality of Karlskrona, from a large grade of participation and a strong bottom-up approach in the days of Agenda 21 to now being more strongly top-down defined by national environmental objectives and principally operated on a professional level..

Geoenergilager Xylem : Visualisering och lönsamhet

Inom svensk process- och tillverkningsindustri finns det stora mängder spillvärme som sällan kommer till användning. Att hitta olika tekniska lösningar för att effektivt tillvarata denna spillvärme skapar både nytta ur ett hållbart perspektiv samt ur ett ekonomiskt perspektiv för företaget.I denna rapport presenteras en utarbetad beräkningsmodell i Excel. Beräkningsmodellen används för att uppskatta lönsamheten för anläggning av ett högtemperaturlager i berggrunden. Excel-filen ska kunna användas för företag som en första uppskattning om ett borrhålslager är ett alternativ för tillvaratagande av spillvärme. Utformningen av beräkningsmallen utgick från Xylems högtemperaturlager i Emmaboda.Beräkningsmallen testades på Xylems borrhålslager.

Business Potential of Software Defined Radio Technology

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

Kan vi inte ha en sån där istället? : om teknisk kravställning på ett fartygsbaserat UAV-system

Detta arbete kretsar kring obemannade luftfartyg, UAV, avsedda att baseras ombord påörlogsfartyg. Regelverk och standarder tillsammans med befintliga fartygs-, helikopter- ochUAV-system utgör ett ramverk inom vilket ett scenario leder fram till grundläggande tekniskakrav för de delsystem som ingår i ett fartygsbaserat UAV-system. Kraven, som är framtagnamed spårbarhet i sjöoperativa förmågor, erfarenheter från den miljö ett luftburet system skaverka i ombord och systemexempel som visar vad som är möjligt att uppnå med dagenstekniknivå, presenteras som ett förslag till värderingskriterier och effektmått med tyngdpunktpå de krav som ställs på luftfartyget (UAV) i sig..

Upphovsrätten incitament eller slutstation? En ideologikritisk analys av The Association of American Publishers och Authors Guilds syn på upphovsrätt.

The aim of the following thesis is to examine if the ideology behind the copyright laws of today poses a threat to creativity and the cultural heritage. The organizations Association of American Publishers and Authors Guild are subject to an ideology- analysis which seeks to examine their ideological views on copyright and the possible threat to creativity such a view brings. The conflict between the two organizations and Google Book Search is used as a context where the ideology is being brought to light. Stanford Law School professor, Lawrence Lessigs work is used as theory and an alternative to the examined view on copyright. The result suggests that the organizations see copyright as the only effective incentive to creation and therefore they think stronger intellectual property laws are needed.

Lärarundantaget - Om patenträttigheter vid universitet och högskolor betraktat ur ett principal-agent perspektiv

Rapporten syftar till att belysa och analysera den svenska lagstiftningen som har kommit kallas lärarundantaget ur ett mikroekonomiskt perspektiv. Lagtexten reglerar patenträttigheter främst mellan enskilda forskare och högskolor. Syftet med analysen är att kommentera eventuella ekonomiska effekter på utformningen av system för ersättning och dess effekter på incitament att bedriva forskning. Ett resonemang om effektiv riskdelning vid kontraktsformulering förs även. Rapporten bygger främst på ekonomisk litteratur och artiklar publicerade i tidningar med ekonomisk anknytning.

Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

Reglerade återköpstider : en studie av svenska återköpsprogram

This study addresses mandatory non-trading periods for Swedish stock market participants which have implemented an open-market share repurchase program during the period 2000 until 2010. By locating the date of publication of interim reports, these mandatory non-trading periods called silent periods are examined. The result indicates that repurchase trading activity occurs despite the statutory prohibition. By studying the price support hypothesis assumptions about long- and short-term effect on share price and performance, this study tries to explain these tendencies. An average decline of share price and performance is shown among companies entering silent periods.

Riksantikvarieämbetet - Identifieringen av balanserat styrkort i en offentlig verksamhet: Hur kan processen vid skapandet av Riksantikvarieämbetets balanserade styrkort påverka dess vidare användning som styrmodell?

The Swedish National Heritage Board (RAÄ) is the agency of the Swedish government responsible for heritage and historic environment issues. During the last couple of years the agency has implemented a new management control system, the balanced scorecard, originally developed for profit driven organizations. Organizations within the public sector have other objectives than profit seeking organizations, and there have been difficulties in applying the balanced scorecard model in the public sector. Therefore we find it interesting to examine the reasons behind these difficulties and believe that some answers can be found in the identification process of the balanced scorecard. Therefore we aim to perform a case study of RAÄ and explain how the identification process of the components of their balanced scorecard can affect further usage of the model as a management control tool.

Vad kostar deltid? Kvinnors deltidsarbete ur ett pensionsperspektiv

Mothers of small children often work part-time in Sweden. Since old age pensions are based on lifetime income, part-time work leads to lower pensions, as long as there is no compensation from non-actuarial benefits such as minimum pensions. In this paper, I investigate whether different components of the Swedish pension system provide incentives for part-time work among women. The analysis is performed through a simulation of future pensions for 9 typical women in a certain cohort. For three levels of education, I compare pensions of women with different labor market participation rates in different growth scenarios.

Interaktiv visualisering av IP-nätverk

Ett icke trivialt IP-nätverk består av många noder som är förbundna med varandra genom olika typer av transmissionsmedier. Man kan föreställa sig nätverket som ett moln av noder och förbindelser. Nätverksvisualisering handlar om att kika in i molnet och snabbt få en övergripande bild över de komplexa relationer som finns i det.Genom att skapa nätverkskartor som grafiskt beskriver ett IP-nätverk kan arbetet med att övervaka och felsöka det underlättas.Telenors svenska nätverksövervakning har utvecklat ett system för att automatiskt generera nätverkskartor i formatet SVG. De har ställt frågan om det går att göra dessa interaktiva och koppla ihop dem med befintliga verktygsprogram.Denna rapport visar exempel på tekniker, baserade på öppen källkod och öppna standarder, som kan användas för att utveckla ett system som gör nätverkskartor i dokumentformatet SVG interaktiva i en webbläsare.Problemet att göra nätverkskartorna interaktiva analyseras och olika lösningsalternativ tas fram och jämförs med varandra.Ett system baserat på öppen mjukvara och öppna standarder utvecklas för att visa hur de redovisade teknikerna kan användas i praktiken. Systemets arkitektur beskrivs i tre systemvyer.

Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
