Förutsättningar för småskalig solelproduktion i Australien
The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.
Han är som han är - En kvalitativ studie om upplevelsen av att växa upp med ett syskon som har autism
The aim of this study is to examine the experienced life situations of siblings growing up with a brother or a sister diagnosed with autism. The study is qualitative and therefore suitable to the purpose of studying the informants´ own experiences. Three women and one man, aged between 18-24 years, were interviewed through chatt programs on the Internet. The constituted perspective is phenomenological and the analysis were made by identifying meaning units in the text from the interviews. The theory used to interpret the result is Systems theory and more specifically the structual family therapy by Salvador Minuchin.
Ledtidsreducering vid Saab Training Systems Ab : Lead time reduction at Saab Training Systems AB
Detta examensarbete är utfört på Saab Training Systems AB i Huskvarna. Saab Training Systems utvecklar, tillverkar och säljer kompletta militära träningssystem.Syftet med arbetet var att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande reserv- och reparationsflöde samt att identifiera problem och komma fram till förbättringsförslag.Vidare har vi studerat reservdelslagrets lagernivå och dess kapitalbindning.Arbetet genomfördes med hjälp av intervjuer med berörd personal, observationer, enkätundersökning samt statistiska studier. Vi har även arbetat med Supply Chain Operations Reference Model som är en öppen referensmodell med vars hjälp man kan kartlägga, förändra och optimera sin verksamhet.Saab Training Systems har som mål att ledtiderna för reservdelsflödet och reparationsflödet skall vara 14 dagar, men i själva verket är det inte så. Dessa ledtider är idag längre, hur långa är dock oklart.De långa ledtiderna beror främst på att i flödena förekommer det mycket passiv tid.
Klassifikation vid de nordiska alkoholmonopolen: En jämförande undersökning av fem statliga alkoholföretags hemsidor
This thesis deals with the goods classification of the Nordic alcoholmonopolies, viz. Alko in Finland, Rúsdrekkasøla Landsins in the FaroeIslands, Systembolaget in Sweden, Vínbúðin in Iceland, andVinmonopolet in Norway. The focus of the study is the web pages of thecompanies (as they appeared April 10th 2011) and the printed pricecatalogue of Alko, from which information on class division has beenexcerpted. The emphasis lies on the division into product groups and theinformation about origin. Within these facets, which partly overlap insome of the classification systems, the principles of division and thehierarchical relations between classes are studied.
Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem
Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Adam Smith och den problematiska värdeteorin
Adam Smith?s economic theory is often subject to criticism, in which it is claimed to be inherently inconsistent. Recently, criticism from well-known scholars has arisen claiming Smith should be characterized a labor value theorist anticipating Karl Marx. This study seeks to analyze whether such criticism is legitimate. Firstly, the economic theory of Smith is discussed in terms of consistency, and secondly, a number of typical and main points of the critique, from the most influential of his contemporary critics, are lifted up and analyzed.
Uppföljning och analys av Stockholms stads solcellsanläggningar
During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..
Utvärdering av digitala provtryckssystem
Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.
Hur min dyslexi påverkar mitt författarskap
The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
Faktorackumulation och inkomstfördelning -En historisk analys av samband mellan ojämlikhet och ekonomisk tillväxt 1850-1930
Uppsatsen ger historiska perspektiv och ekonomiska analyser av samband mellan ekonomisk utveckling och ojämlikhet. Den teoretiska utgångspunkten är två artiklar av Oded Galor och Omer Moav som utarbetat formella modeller för analys av ojämlikhetens inverkan på tillväxten, med betoning på humankapitalets ökade betydelse i ekonomins senare utvecklingsstadier. Den empiriska undersökningen som författarna gör i artikeln ?Das Human- Kapital: A Theory of the Demise of the Class Structure? för England, är mallen för uppsatsen. Resultaten av den empiriska studien för Sverige ligger i linje med Galor och Moavs slutsatser för England men ett särskilt svenskt utvecklingsmönster spåras..

This study intends to illuminate women?s experiences of their own self-harm. Self-harm is mostly associated with women and research shows that women mostly are over-represented. This study describes women?s experiences about their self-harm but also how they perceive the elements around them during their illness.
Termomekanisk analys av svarvstål : Volvo Aero Corporation
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Ekonomisk policy och tillväxt i en transitionskontext: en studie av realsocialistiska länder
Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory.
Hur hanterar institutioner en miljö med blandade Operativsystem?
The purpose of this thesis is to investigate if there are environments that use
some kind of central authentication system within institutions/schools. The
hypothesis is that an institution not using a form of central authentication
service has more need for maintenance and as such is considered a higher cost
for the organization.
