Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

Based on Theodor W. Adorno's theories about the relation between society and lyrics, and critical theories about postmodernism, it can be seen in Bob Hansson's lyrics how he tries on the one hand to write in a modernistic tradition but, on the other, is very influenced by postmodernism which results in a conspicuous self-distance and self-contempt..

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..

The main goal was to develop a reservation system and to make it work with Dreamgallery, to develop a demonstration version of the system. The thesis describes the approach for developing an easy-to-use and customisable program and interface for making reservations. How this is inserted into an existing program in a suitable way.

The reason for this study is to settle the balance between technology and preponderance in war. Each theory claims its own superiority to be decisive when it comes to achieving military victories, but this study will show what actually happens when the two theories are analyzed together in the same conflict. To prove the conclusions, a case-study on Operation Gazelle is used. The study will describe the theories, what a military victory is and which party in the conflict came out victorious after this specific operation. Both sides? forces will be shown and compared.

The aim of this essay is to investigate what is burnout and how women who are affected by it manage their condition. Furthermore, we have investigated stigma and whether or not those affected by burnout are in turn stigmatised.A qualitative approach has been used to achieve our aims with this project. To support our analysis we have interviewed ten women who all have been diagnosed with fatigue syndrome along with studying relevant literature. The main theories used in this investigation are the symbolic interaktionism by G.H Mead, the term stigma by Erving Goffman and different theories on coping.The results show that the majority of women in the study had suffered from burnout due to work related stress and changes in their working environment. How they coped with and recovered from the condition depended on their own activity and how it related to their own support system.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

This essay constitutes a qualitative case study about democratization theory and the middle class in Russia. This is a very important case to study, especially because of the geographic position of the country as well as the economic importance Russia has as a part of the G8. In the essay the author seeks to answer the question whether the lack of a significant middle class in Russia can be a part of the explanation to the absence of a well functioning democracy in the country. Several democratization theories are presented. The most important being Ruth Berins Collier's theories about ins and outs plus the elite- or working class as the initiator of democratization processes.

This study sought to explore the juvenile crime prevention in Sweden which for the purpose of this report is seen as efforts towards preventing youth criminality and all forms of anti social behaviour by young people.In the study, interviews with six social workers working directly or indirectly with young offenders were conducted. The interview results were analyzed and subjected to transnational comparison with the practice in Kenya. The report explores existing literature on situational crime prevention, restorative justice, the link between drugs and crime, attachment to parents, peers and involvement in convectional activities, gender differences in criminality, partnerships in crime prevention and the juvenile justice system. It uses control, strain, feminist and social disorganization theories to explain the causes of delinquency, analyzes the perceptions of social workers and discusses what works in juvenile crime prevention. The report identifies the causes of delinquency in Kenya and in Sweden as well as the prevention programs that social workers perceive as effective in addressing youth crime.

This thesis explores the effect of using a new media in the marketing mix. SL, in cooperation with Clear Channel, has covered the outside of an entire carriage, 46,5 meters long, in an underground train with an advertisement for a company. This new form of advertising has taken place in the Stockholm Underground system during spring 2005. The five companies participating in this project are MTV, the Aftonbladet/Sportsbladet, Eniro 118 118 SMS, Heinz and the Gallerian.An empirical study has been carried through to survey the motive for companies to market themselves, their brand and product/service, by using the outside of a carriage on an under-ground train as a gigantic, mobile bill¬board. The study also investigates the commuters? attitude regarding this form of advertising.

Linjäriseringar av olinjära system är mycket relevanta eftersom det finns en i förhållandevis enkel och omfattande matematisk teori kring linjära system, till skillnad från allmänna olinjära system.För vissa olinjära system är det svårt eller inte ens möjligt att genomföra en analytisk linjärisering.Orsakerna till detta kan vara hög komplexitet av systemet eller avsaknaden av ett analytiskt uttryck.Numerisk analys kan vara en lösning på detta problem.I detta examensarbete används framåtdifferens och centraldifferens för att genomföra de derivata-approximationersom behövs för att genomföra en numerisk linjärisering av ett olinjärt system.Rapporten behandlar även vad som sker då det är dålig upplösning på den indata som används när man genomför enlinjärisering, vad som händer med heltal och binära signaler om de ingår i ett system som linjäriseras ocheffekten av att ha olika samplingstider för olika delmoduler i ett system som linjäriseras.Slutligen undersöks numerisk bilinjärisering av ett system på bilinjär form och en jämförelse mellan analytisk linjärisering och bilinjärisering görs..

The purpose of the following thesis has been to study librarians' attitudes towards comics for grown up people. I have compared the attitudes among the staff in two public libraries in Sweden, Malmö public library and Lund public library. I have conducted five interviews with librarians and observed how the comics are handled in each library. I have also carried out a literary study of the history and theories of comics. Initially a definition of comics is presented, and then an overview of the development of comics and of some theories regarding them is offered.

Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad.
