Denna rapport är inriktad på batteribesparing för platsbaserade applikationer i Android. Rapporten kommer att analysera och ge konkreta förslag på hur man på ett batterisnålt sätt implementerar lokalisering av Androidenhetersgeografiska position (latitud- och longitudkordinater) samt frekvent hämtning av data via HTTP från en back-end server. De lösningar som tas upp i den här rapporten är specifikt tillämpade för applikationen MyWorld men kan anpassas för vilken platsbaserad applikationen som helst med liknande behov. Målet är att förbättra och optimera utvalda områden som tidigare implementerats i den här applikationen. De nya optimerade lösningarna har genomgått två olika testscenarion där mätningarna visar att batteriförbrukningen har reducerats med 4,2% för applikationen då den aktivt körs och används samt 14,8% för applikationen då den är icke aktiv och enheten inte aktivt används..

Prior studies have shown that earnings management can be used either to inform or to mislead investors about the future performance of a company. However, few studies have examined the impact of earnings management on forecasting return on equity (ROE). The aim of this thesis is to investigate whether the ability to forecast next year's ROE is improved when taking earnings management, measured as discretionary accruals, into account. This is examined by comparing a forecast model that takes the magnitude of discretionary accruals into consideration with a model that does not. The study is based on companies that were listed on the Stockholm Stock Exchange during 2002-2012.

This is a qualitative study where the purpose was to investigate what professionals experience to be the reason for an individual to become addicted to gambling and continues to gamble even though it leads to negative consequences. The purpose was also to investigate what the professionals experienced was of importance for an individual to recover from a gambling addiction. The study was based on qualitative semi-structured interviews with knowledgeable individuals in the field. The main findings of the study were that the motivation for individuals with a gambling problem to continue gamble was that they saw gambling as the solution to their problems by winning back lost money. It was common that gambling was an escape from anxiety, guilt, shame, and other gambling-related problems such as financial liabilities.

Events that have effected music teachers? view on education - Interviews with four violin-teachers.

Since a few years back television has been on a verge of an enormous digital change. Web-TV is now growing at an incredible rate and is said to completely change the way we consume TV. The purpose of this essay is to determine and gain an understanding of how representatives of the broadcast industry looks at the phenomenon of web-TV and especially the different kinds of online video services and how they believe this will affect the television. Methods used are qualitative interviews which we compared with previous studies on the subject and acknowledged communication theories. The respondents were people with good insight and understanding of the media and TV industry.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The connection between accounting and taxation goes back to the 1920s laws of the named areas. A proposal has now been brought forward, the so-called SamRoB-investigation, which means that the connection between accounting and taxations should be decoupled.The authors? aim with the study is to investigate what a possible decoupling between accounting and taxation, i.e. the formal connection and the untaxed revenues, implicates for the auditor´s work.A research has been done by interviewing two authorized auditors and one authorized consultant of accounting to get a view in how the auditor?s works could be affected.

Det här arbetet utreder en alternativ metod för mätning av varvtal hos likströmsmotorer. Det är idag vanligt att man använder sig utav givarlös feedback i reglersystem för att nå lägre produktkostnader. Nackdelen med metoden, som utnyttjar den över ankarlindningarna inducerade spänningen (back EMF), är dålig precision jämfört med system med varvtalsgivare. Denna alternativa metod utgår ifrån att motorströmmen varierar periodiskt med varvtalet på grund av asymmetrin i motorn. Genom analog filtrering av motorströmmen samt digital signalbehandling som arbetar utifrån autokorrelation är det möjligt att skatta varvtalet utan givare.

Lifelong learning (LLL), a concept dating back to the 1920s, is much used both by the OECD, UNESCO and the EU. But while intergovernmental think-tanks and supranational organisations often use the term in a positive sense, many (not least scholars) are critical of the term. The critique either deals with the lack of a universal definition, that the implicit responsibility for LLL has shifted onto the individual, or that the meaning of the term has shifted from a humanistic one linked to the personal development and a better society to a neoliberal one that involves growth, competition, globalisation and human capital theory. This study is based on interviews with nine trade union representatives on their understandings of lifelong learning. The results showed that while LLL was positively viewed by most, there was virtually no communication vis-à-vis members on the topic, most trade unions have no policy regarding LLL, and responses from representatives were sometimes self-conflicting..

Online social networks are a natural part of the lives of today?s western youth. Media and information literacy is a central part of research in Library and Information science and until now there has always been more focus on these subjects in a learning context rather than in an every day life context.The aim of this study is to further examine how adolescent boys value and trust the information they receive via Twitter in their personal lives, and how this effects their view of their environment. The study was done with a qualitative method, where we conducted interviews with six boys who were all born in 1997. The results showed that they knew how to react critically to information on Twitter.

This study investigates the judicial process against Erik Molin, a clerk and former theology student at the University of Uppsala 1734-1739. The main purpose has been twofold; first to investigate the legal process through the various judicial bodies and secondly to analyze the ideas and conceptions about man and society expressed by the authorities and Erik Molin. The theoretical approach has been inspired by the German philosopher Jürgen Habermas? theories concerning the emergence of the bourgeois society and the changing concepts of private and public spheres. The study shows that the diocese of Uppsala regarded Molin's theology as heretic and found that he knowingly had tried to spread his views.
