Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

Examensarbetet är utfört vid BAE Systems Bofors AB i Karlskoga. Projektet har gått ut på att utvärdera den nya teorin STAMPoch testa det tillhörande verktyget STPAinom säkerhetsarbete mot det avgränsade ARCHER-systemets delsystem granatgrip-/lyftdon.I dag blir systemen mer och mer komplicerade och de nuvarande metoderna har inte utvecklats i samma takt för att göra en grundläggande säkerhetsanalys då många av olyckorna härrör från oförutsedda interaktioner. Teorin och verktyget är en nyutvecklad metod för att identifiera och värdera risker i ett system eller en produkt. Företaget har ännu inte satt sig in tillräckligt i professorn på MIT, Nancy Levesons rapport som ligger bakom denna nya metod för att arbeta med riskbedömning. Eftersom det är en relativt ny teori inom säkerhetsarbete så finns det inte speciellt mycket forskning att tillgå och antalet källor som finns tillgängliga är få.

Syftet med detta examensarbete var att undersöka vilka faktorer som påverkat acceptansen hos användare, inom den kommunala verksamheten, vid införande av ett datoriserat system. Med acceptans menas att användarna ska kunna utföra sina arbetsuppgifter på ett bra och lätt sätt. Studien har gjorts utifrån användarnas perspektiv.Genom att genomföra en intervjuundersökning på ett flertal kommuner där användarna använder systemet Vabas/Duf, har undersökts hur användarnas upplevda acceptans påverkas av faktorerna delaktighet, användbarhet och lättanvändhet, vid införande av ett datoriserat system. Delaktigheten vid införandet av ett system innefattar även information och utbildning.Resultatet från undersökningen visade att delaktigheten ökade användarnas acceptans. Ingen avgörande slutsats kunde däremot dras mellan acceptans och faktorerna användbarhet och lättanvändhet, då resultatet från de båda grupperna inte visade någon märkbar skillnad..

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

This master thesis was performed at IdaInfront AB. The aim of the thesis was toinvestigate how the design principles ofthe user interface in Windows 8 can beapplied to a case management system. Theuser interface in Windows 8 is based ona design language called Metro and it isprimarily designed for touch screens.Ida Infront AB wanted to know whatpossibilities and limitations the Metrointerface offers.The study has resulted in a prototypeapplication that is developed in Windows8. The prototype shows how the Metrointerface can be applied on a casemanagement system. Some limitations inthe usability have been identified inthe Metro interface when applied to acase management system.

The implementation of IFRS 2 led to significant changes in the accounting practices for corporations regarding stock related compensation. The new regulations required firms to account for the stock based compensation as an expense in the financial statements, rather than merely disclosing the information in the notes section to the statements. Following prior research on the area; specifically studies made in the U.S., where researchers find that companies change their use of stock based compensation due to the increased accounted expenses, this study hypothesizes that the same pattern may be found among companies listed on the Swedish stock market. The results of this study show that the use of option incentives has decreased during the studied period 2001-2008 and that the decrease in part can be derived from IFRS 2 and in part from other factors. The results are useful to future research, as they provide an overview of the effects that IFRS 2 had on companies, and various factors that influence the behavior of corporations, as well as in a larger perspective be a factor to take into account for future modifications of the IFRS..

This study examines whether there is an association between the length of the client-auditor relationship and audit quality, using absolute unexpected accruals estimated by industry as a measure of audit quality based on a modified Jones model. The study is motivated by the proposal on mandatory audit firm rotation for publicly traded companies from the European Commission, which is based on the notion that longer auditor firm tenure creates a familiarity threat which reduces the audit quality. Both the relation between audit quality and auditor partner tenure and audit firm tenure is examined in this study, using multivariate regression controlling for auditor type (Big 4 versus non-Big 4), signing auditors (one versus two auditors), firm size, profitability, leverage and age. There is a significant negative relationship between audit quality and audit partner tenure when only companies employing Big 4 is tested, which indicate that auditors constrain managements extreme accounting measures with longer tenure. The results provide no significant evidence of an increase in the absolute unexpected accruals with audit firm tenure, when only Big 4 companies are tested.

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

The purpose of this master?s thesis is to examine how comics, here defined as a combination of text and images, are handled by the libraries in regards to subject analysis, classification and indexing. A comparative approach has been used in this study. First, common practices, methods and theories concerning subject analysis developed for documents consisting of text or images are presented. Then the current systems at two special libraries, specializing in comics and consequently dealing with both text and images, are examined and related to the above mentioned practices, in order to discover differences and similarities.

In 1995, the World Trade Organization WTO was established. Today WTO has nearly 150 member countries, accounting for over 97 percent of the world trade. WTO has a number of agreements and one of them is the General Agreement on Trade in Services GATS. GATS control the service sector, and the public library is a small part of this sector. The purpose of this study is to examine the Swedish debate about GATSs possibility to affect the public library.

Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made. A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

The starting point of this paper has to do with rapid changes within the information technology and the need for agile and fast systems. The primary goal is to investigate what happens with recordkeeping practices in agile environments like service oriented architecture (SOA). It is in the possible transfer between IT architecture and digital archive the area of this paper resides. The paper relates to the Records Continuum model by which records will be considered historical and active at the time of creation. In the Records Continuum model recordkeeping practices and archival requirements will have to be taken into account at the time of creation.This paper concerns SOA from the perspective of Archival and Information science.

By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..

This master thesis investigates the user education. Christine Bruce has presented a theory of information literacy in her research which has resulted in seven different aspects of information literacy. In this study I wanted to investigate what aspects there were and what they looked like in a practical educational situation. The methods used for this study were observation and a questionnaire. I analysed the observations by using Bruces aspects of information literacy to group the observed activities into the different aspects.
