Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

The present study sought to examine the collaborative role of the student organization Here 4 U and the impact of this collaboration on the organization and its partners. As a point of departure a questionnaire was distributed to supervisors, principals and other cooperation partners of Here 4 U, the most prominent quantitative results of which were related to previous research, new institutional theory and empowerment theory. It turned out that partners interacting with Here 4 U felt that the collaboration was necessary and wanted to continue with it. The respondents to the questionnaire were asked to define the concept of collaboration. Factors emphasized by respondents included feeling of community, security, and common goals.

There has been an increase in the importance and amount of information concerning publicly traded stocks in recent years. When analyzing and valuing stocks finding new ways of collecting information has therefore increased in importance. This thesis aims to explore how meetings with management can impact the stock valuation done by the security analysts. Furthermore the case study examines what kind of information analysts can receive by interpreting management at these meetings. This case study of ten Swedish security analysts show that the analyst?s stock valuation is directly or indirectly affected by the meetings.

Cambodia, in Southeast Asia, has tropical monsoonal climate with distinct dry and rain seasons. Many people are poor and live in rural areas. Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.

The world is increasingly coalescing, ecologically, economically and culturally. Many problems can no longer be solved within the own state borders and the limitation of the territorial state is obvious. Jürgen Habermas means that a world domestic politic without a world government is what this progress need. Therefore it is important that national interests become less central and the solidarity between people is given priority in international relations. The focus of this thesis is therefore a critical discourse analysis of the current position of the internationalisation of Swedish security and defence policy.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

During 2001-2002 a prototype, IMIS (Integrated Mobile Information System) was developed at BTH (Blekinge University of Technology) to demonstrate how mobile IT-systems can be used in healthcare. The prototype was based on the activity theory of Engeström. An ongoing project started in spring 2003. The purpose of the project is further development of IMIS with special focus in the diabetes healthcare. Participants in the project are scientists and students at BTH, ALMI Företagspartner, Blekinge FoU-enhet, Barndiabetesförbundet Blekinge, Blekinge Diabetesförening, Vårdcentralen Ronneby and Vårdcentralen Sölvesborg.

The project has involved the development of two kinds of shooting targets in partnership with Marcus Bergkvist and Christopher Åkerblom. The project from the client was divided into two parts. This thesis discusses solutions for hands-on transport, development of tripods and an overall design. The second thesis affect resetting systems for the products.The work was done with a process and methodology based on design perspectives. This process has involved the search of relevant data which has provided the platform and opportunity for appropriate and purposeful design work.Concept development has been done using hand sketches and Photoshop, where a simple visualization of different concepts for the tripods has been produced.

Dagligen interagerar människor med IT-system och internetanvändning har blivit en viktig del i många människors liv. Med fler användare än någonsin hanteras ofantliga mängder information och samhället ställer allt högre krav på IT-säkerhet. När det gäller att skydda sin integritet, tillgänglighet och sekretess vid internetanvändning fokuseras det ofta på tekniska åtgärder, såsom brandvägg och antivirusprogram. De tekniska åtgärderna skyddar användaren till viss del, men det räcker inte för att förhindra ett bekvämt och naivt mänskligt beteende. När säkerheten brister beror det oftast på den mänskliga faktorn.

The purpose of this essay is to analyse and compare pneumatology in Eftertanke in Kyrkans Tidning, in a Swedish evangelical Lutheran context, with pneumatology in Luthers Small Catechism and Luther's Large Catechism. Through a descriptive, inductive and hermenutical approach the essay intends to answer two main questions regarding how these sources 1) describe the character features and 2) the function of the Spirit. The conclusions of this essay show that the character features of the Spirit in Eftertanke differ from the catechisms in describing the Spirit with words connected to nature and life, while the catechisms only describe the Spirit as holy. The discussion that follows implies that the Spirit in the catechisms is depicted as more personal whereas Eftertanke depicts the Spirit more as an impersonal force. There are similarities in how both the catechisms and Eftertanke depict a dialectic relationship between human beings and the Spirit. However, they differ in function: in Eftertanke the Spirit is foremost a giver of life and a creator of positive emotions as well as a giver of guidance, while in the catechisms the Spirit is foremost a sanctifier.

The purpose of this qualitative interview study was to examine which approach experienced pre-school teachers have on children that seek negative attention. The study contains five informants in a city in the middle of Sweden and they all have at least 10 years of experience after their diploma from a pre-school teachers? program. The questions I aimed to answer were the following: How did the pre-school teachers define the expression ?negative attention?? What approach did they have on children that seek negative attention? What effects do the childrens? seeking of negative attention generate on their self-esteem and sense of security? How possible do the pre-school teachers feel it is to achieve the goals of the pre-schools? curricula that every child should get their needs respected and met, when they work with children that seek negative attention? The results showed that the teachers think of them as resources in the group and that they need to think of the environment around these children both at home and at the pre-school to better meet their needs.

Ett verktyg för datorstödd interaktiv utbildning, Web-based Training, har utvecklats på Sigma Information Design. Två olika utvärderingsmetoder har använts för att öka dess användbarhet: heuristisk utvärdering och användartestning. Heuristisk utvärdering är en analytisk metod där expertutvärderare inspekterar gränssnittet för att predicera (förutse) användbarhetsproblem. Användartestning är en empirisk metod där tänkbara reella användare deltar och användbarhetsproblem observeras. Föreliggande studie fokuserar på användbarhets-problem som både prediceras med den analytiska metoden och observeras med den empiriska, så kallade ?träffar?.Analytiska metoder predicerar användbarhetsproblem genom att utpeka bristande ?intrinsic features?(gränssnittsegenskaper).
