Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Självkänsla, och särskilt strävan att öka självkänslan genom yttre bekräftelse, har visat sig vara en betydelsefull komponent för hälsa och välbefinnande. Kompetens- och relationsbaserad självkänsla är två typer av betingad självkänsla och den föreliggande studien fokuserade på betydelsen av dessa för upplevd stress samt självskattad psykisk och fysisk hälsa. En surveyundersökning genomfördes där 111 deltagare i åldrarna 19-64 år deltog. Resultatet visade att betingad självkänsla, särskilt den relationsbaserade, hade ett starkare samband med psykisk hälsa än fysisk. Det fanns även skillnader i psykisk hälsa beroende på kön, ålder och nivån av betingad självkänsla.

The purpose of this study is to investigate and describe what factors are most important to students when choosing training center, and how these factors affect the choice of each training center. We investigated this by performing a qualitative research and a quantitative survey of students at Karlstad University that trains at Friskis & Svettis and Sats in Karlstad. The results show that there are a number of important factors in the total customer experience that affects a student's choice of training center and that they also differ between a premium center and basic center. Our conclusion is that when a total customer experience concept consists of a core, core experience and peripheral experiences well linked into each other competitive advantages is created, resulting in more satisfied and loyal customers. .

Our study aimed at gaining insight of co-workers experiences of different factors that affects the verbal communication and leads to dialogue and misunderstanding between co-workers and their managers. The empirical material was gained from semi-structured interviews with co-workers at various departments within the same organization. We used a hermeneutic interpretive approach and our data was analyzed concerning different factors affecting communication. The result has been interpreted using the theories of deliberative conversations and dialogue competence. We have also used Illeris theory of learning. The result shows a number of factors that affects communication between co-workers and managers.

It has since long been noticed that savior figures from different religions have reminded of each other, and there are different theories trying to explain why. This study examines religions operating in the same culture, and in this case, judaism and zoroastrianism, and their influence on each other. In particular, focus is on zoroastrianism's image of the savior figure Mithra, and how this representation may have influenced the description of the Messiah in the Talmud. How are the two figures represented in the scriptures and what similarities can be identified?By a thorough content analysis the studie examines the Avesta of zoroastrianism and the Talmud from judaism.

The purpose of the study is to examine how the teachers in second grade use SMART Board and compare two schools.The process I used was qualitative interviews and classrooms observations. Previous studies shows how widely SMART Board is used in classrooms, and this has also been shown in my study. The study shows how differently SMART Board is used in the classrooms, and how important education in the technology of SMART Board is to achieve in the classroom. The final discussion clearly shows similarities and differences in the use of SMART Board in different classrooms and also the teachers? thoughts about SMART Board as a tool.A central aspect in the use of SMART Board shows how important the basic education in SMART Board is.

The purpose of this study was to investigate the relationship between mental illness and socioeconomic factors such as education, age and gender among drug users. Descriptive and ANOVA analysis were performed to 68 structured interviews (Addiction Severity Index basic). Analysis addressed associations between drug usage and level of education, age and gender. Results showed gender differences in self-rated mental health with women drug users rating their mental health lower than men. In addition, there was no association between age, educational level and self-rated mental health.

The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

This study focuses the development on the protection of landscapes with old industries and how it nowadays is appreciated by the inhabitants.

Emotional Intelligence (EI) is a highly used concept in contemporary organizations, especially in the recruitment process or education of employees and managers. The aim of this study was to examine the discursive production of the concept emotional intelligence and how it, linked to an organizational context, is expressed in web-based articles and course homepages. In total 11 texts related to emotional intelligence and organizational contexts were used as the object of study. A three-stage model was used as a method for analysis. The model included a content analysis, argument analysis and a deconstruction analysis in order to expose what was said about emotional intelligence and how it was said.

The purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C). The program is written in Visual Basic .NET and I choused that program language because it is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.

On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.
