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.

This Master?s thesis presents a descriptive study of the intellectual process to describe images in such a way that they can be incorporated into written information systems. The purpose of the thesis is to concentrate on the scientific development for the last two decades, in the area concerning the description of images so that they can be organized and incorporated into information systems and possible to retrieve when searched for. Library and information science (LIS) has a strong tradition of turning to the iconographical theories of Erwin Panofsky and to semiotics according to Roland Barthes, for models and theories for the interpretation of images. The question for this thesis is whether LIS in this scientific field, has deviated from these models and theories, or are Panofsky and Barthes and their scientific work still providing for intellectual and practical guidance for LIS within this area..

This thesis aims towards an understanding of information systems and subject representation in relation to academic disciplines. This is achieved by comparing how a discipline, History of science and ideas, represents itself compared with the subject representation of its dissertations in an information system, LIBRIS. The point of departure for this thesis is the domain analytic view of Hjorland which states that the quality in information seeking is enhanced if the subject representation considers the contexts in which documents are produced and used. The importance of concepts such as domain and discipline is discussed. The disciplines view of itself is established by the study of articles written by scholars in the discipline, by how the discipline presents itself on the homepages of five university institutions and by the examination of titles and keywords given to dissertations in the discipline.

The main aim in this Master thesis is to analyse how an ideological view may have influenced the shape of hierarchies with a specific concentration on the concept of fiction genre in the latest versions of the systems SAB and DDC. Our thesis is that no theoretical classification scheme can be recognized as objective. With an ideological/institutional perspective we look at the structures behind these systems. As a vehicle we use the hermeneutic circle to show the play between part and unit by focusing and analysing three different levels: the content level the concept level the ideological level. The first level is in the shape of a historical background and an analysis of concept with focus on content.

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..

Computer use at work has risen considerably over the past fifteen years and is currently a relatively common phenomenon when 76 percent of women and 72 percent of men using the computer in their daily work (SCB Arbetsmiljörapport 2009).According to Gulliksen and Göransson (2009), Sweden is one of the countries which are more advanced in the procurement of computer systems at work. He means that Sweden has unique opportunities and conditions for user participation in the development of computer systems, when the user has the right to influence their working environment through a law in the Work Environment Act. The paper examines the importance of user involvement in system development and the Swedish company's approach and experience of user involvement. To highlight and explore the importance of user involvement, there has been a case study in which users have been representative of the development process. The case study has been conducted on a case company where the system IST analys was in need of a new interface.

The purpose of the study is to investigate how much interest media has shown selected topics in the corporate governance systems in Germany and Sweden. The four selected aspects are: ownership structure, employee representation on the boards, disclosure of board members? compensation and female directors on the boards. The reasons for and consequences of the similarities and differences will also be discussed. The German and Swedish corporate governance systems construct the key basis of the study, emphasised on the four chosen aspects.

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

Health care costs in relation to GDP are escalating all over Europe and the Swedish health care industry is not an exception. Between 30 and 50 percent of resources used in health care are considered waste, in the sense that they don't contribute to increased health. This illustrates the big need for hospitals to become more efficient which is why many hospitals today are trying to move towards a process-oriented organization. This paper therefore aims to identify the elements necessary for this type of organizational change, the barriers encountered when moving from a functional to process oriented hospital as well as how to overcome them. The case study was conducted at Karolinska Universitetssjukhuset and shows the importance of not just transmitting a sense of urgency but also communicating that the upcoming change is long term.

The aim of this thesis is to, from a feminist point of view, analyse the Universal Decimal Classification UDC, which is an international and widely used classification system. A number of the larger classification systems and subject heading lists have during the last decades been placed in the limelight of various gender studies and the systems treatment of women has been criticized. With this examination of the UDC, I dont merely wish to identify shortcomings and advantages with the UDCs way to treat men and women. The UDC is also used as an example of how the gender problem can be identified and interpretated in classification systems generally. My analysis is performed with a theoretical foundation in feminist science theories about knowledge and norms, together with a linguistic perspective on valuing and emotionally tinged language.

Många liv räddas idag då mammografiscreeningen som erbjuds symtomfria kvinnor tillhörande riskgrupper för bröstcancer, gör att cancer kan upptäckas på ett tidigt stadium. Screeningen utförs med röntgen, vilket är den metod som anses mest lämplig. Metoden är förhållandevis snabb och billig, men den har några nackdelar. Den kan vara ospecifik då man med denna metod avbildar skillnad i densitet mellan tumör och frisk vävnad, och ibland är denna skillnad så liten att det är svårt att detektera på bild. Bröst med högt innehåll av körtelvävnad försvårar även detektionen ytterligare.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The current financial crisis has left its mark. It has even hit the major Swedish banks who have shown large losses. The media has not been slow to take note of this, and the constant political debate about the bonus culture has been reinvigorated. Our aim is to find out how the major Swedish banks relate to the publicity and describe how and why senior executives are rewarded, and what strategies banks are using in the design of their reward system to maintain a legitimate behavior, and thus the confidence of its stakeholders.As a starting point to answer our purpose we have used the agency theory that describes our view of how various problems occurs and how incentives can be established in order to get senior executives to act for their owners' interests. Modern theories of reward systems are taken from a variety of authors, these theories give us an insight into how reward systems can be designed in banks.

Att kollidera är en av riskerna som föreligger då ett fartyg framförs till sjöss trots att det finns internationella regelverk, så som Sjövägsreglerna, enbart utformade för att förhindra detta. I denna kvantitativa litteraturstudie har det undersökts vilka avvikelser från Sjövägsreglerna som bidragit till kollision samt hur regelavvikelserna skiljer sig utifrån fartygstyp, tid på dygnet, sikt och bryggbemanning. Haverirapporter utarbetade från två haverikommissioner har undersökts och utifrån haverikommissionernas egna slutsatser om orsak till kollision har författarna sedan identifierat vilka Sjövägsregler fartygen avvikit från vid kollisionen. Två haverikommissioner valdes för att kunna jämföra om det finns skillnader i resultatet i deras utredningar. I en majoritet av kollisionerna hade fartygen avvikit från någon eller några av Sjövägsreglerna.
