Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

Students at Jönköping School of Engineering were given an assignment from Jönköping municipality, to evaluate their decision support system, QlikView. The students have also developed proposals for improvement with focus on usability.The Jönköpings municipality has currently got 11000 employees and consists of nine different administrations. The target group for QlikView is approximately 600 first-line managers.The intention of QlikView is that the users can get an overall picture of their business by having all information in just one system.The purpose of the thesis is to obtain a picture of what the users think about the system today and present relevant suggestions for improvement, which the Jönköping municipality can use when the introduction of the new version of QlikView takes place. The research questions that the study aims to answer are:? Has QlikView got a user friendly interface?? How can the interface be improved to become more user friendly?Theories that this work is based on is Jacob Nielsens ten usability principles and Ben Schneidermans eight golden rules.

The purpose of this Master?s thesis is to investigate how public library users consider the knowledge of the librarians and to examine what the users expect from the librarians. To begin with, we contemplate our own view of the librarians, their knowledge and what help we expect at the library. Realising that we do not expect particularly much from librarians, although we have studied to become librarians for two years, we assume that the regular library user does not expect much either. This assumption resulted in our decision to investigate this particular question.

This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.

The public library is an institution that throughout history has been associated with anumber of social codes, that seem to be deeply rooted in the minds of the public. Thesecodes regulates how users act and interact in the library environment and as a library useryou have to obtain knowledge about these social codes.This master's thesis aims at studying how these codes are transferred to children in the earlyschool-age, how children react to the social codes and what effects they have on thechildren's development into library users.The empirical material used in this study consists of observations and interviews. Theobservations are conducted during two school classes visits to a public library and focuseson the interaction between librarians, the children and their teachers, and the interviewswere conducted with the two librarians responsible for the library visits.The theories used in this master's thesis consists of symbolic interactionism, in the form oftheories by George Herbert Mead and Erving Goffman, Peter L. Berger and ThomasLuckmanns theories regarding the concept of institutions. Another theory that's used in thismaster's thesis is the one concerning the social aspects of information literacy focusing onthe concept of epistemic communities as presented by Kimmo Tuominen, Reijo Savolainenand Sanna Talja.The result of this study is that the social codes are communicated to the children primarilyby the teachers rather than the librarians.

This thesis is about language planning in Faeroese libraries as seen from the countrys specific situation, with Faeroese as a mothers tongue, but with great dominance of the Danish language within media. The purpose of my thesis is to examine language planning activities within the library, and the consequences this planning has for the system. Different theories about language planning provides a framework for my model of the library as a linguistic eco-system with actors performing status planning, represented by the government with its influence in cultural politics, the librarian with his or her library tasks and the user with his or her needs. The thesis has a qualitative attempt, and the empirical material consists of different documents about the country and materials from interviews made with seven qualified librarians, employed within general libraries in the Faeroe Islands. The analysis shows that the librarian in different ways promotes the Faeroese language within library activities, and because of the attention paid to the user in the public library he/she influences the librarians planning.

Idag kopplas ofta etik inom användarmedverkan till behovet av användare i utvecklingsstadiet av IT-produkter. Det är svårt att hitta etiska riktlinjer för bemötande av användare genom en projektprocess. I denna studie hanterades detta genom att identifiera etiska temaområden relaterade till bemötande och samarbete med användare genom en litteraturstudie. Studien syftar till att undersöka hur praktiker hanterar utmaningar som de upplever vid användarinvolvering i ett IT-projekts olika stadier. Den syftar även till att ge praktiker stöd vid upptäckt och hantering av etiska utmaningar.

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

This thesis was performed at SverigeGrepen AB. SverigeGrepen is a company that hasone product on the market; a manure fork that is designed to be used for mucking inshavings or peat. The aim of this thesis was to develop a new manure fork that isadapted to be used in straw.The development started with a pilot study where experience of mucking wascollected to be able to understand what and why certain characteristics are importantfor the function and use of the manure fork.A basic concept was developed where the main function was fulfilled, which meantthat a separation between dung and straw could be performed in a way that wasbeneficial for the user.The work resulted in four concepts of how a manure fork could be used in the strawthat can be designed and constructed. The conclusion that the work gave was that allconcepts met the main requirements required by a manure fork to use in straw.However, concept four provides a good visual impression, while its benefits areassumed to be important qualities..

Bitcoin is a digital currency that is used by people all around the world. The goal of this paper is to give an idea about how much trust there is in bitcoin among its users. This paper has used an online survey aimed at bitcoinusers and a content analysis to collect data about this trust.The conclusions show that there seems to be some trust in bitcoin as a technology and this is based on that the users have a good understanding about how bitcoin works. They also share their knowledge about bitcoin to people around them. The trust between people in the bitcoin network on the contrary doesn?t seem as high because certain technological properties hurt this trust.

Self- determination and autonomy of elderly people living in long- stay care homes is the forefront of discussion in the media and in society today. It examines the extent to which elderly people actually have the opportunity for self- determination and to what extent they have an impact and influence in their daily lives. A suitable way to look at how the quality of long ?stay care looks like is too look at the extent to which the user has self- determination. The aim of our study was to examine how self-determination appears in long- stay care homes. We also talk about in what way the officials perceive self- determination and how elderly identify and perceive their right to self- determination and the importance it has for the individual. The essay has been made with the help of interviews and surveys on a number of long-stay care homes in Skåne.

This pilot study investigates possible treatment effects and participants' experience in an internet-based treatment of specicfic phobia. Changes in self-reported phobic fear were examined in a series of case studies and changes in attitudes towards avoidance and approach strategies were examined at group level. Seventeen DSM-IV diagnosed patients with specific phobia participated and 10 out of these completed the treatment.The results show that 80 % of the completing participants were clinically improved after the treatment and that the completing participants were significantly more negative towards avoidance strategies after the treatment. The evaluation of the disposition and user-friendliness of the treatment showed that the participants' overall view of the treatment was positive. The main advantage perceived was the flexible nature of the treatment, while the main disadvantages were the high level of motivation and discipline required from the participants.

The purpose of this study is to find out how and to what extent doctors use the hospital library?s collection of print and electronic medical journals. Major changes have the last years occurred in the journal collection. The journals are very costly and little is known about the user satisfaction with them. Therefore it?s important to examine how satisfied the users are with the collection and how they utilize it.

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.
