Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

My intention with this study was to examine the concepts ?mother tongue? and ?mother tongue education? and how these concepts are understood by some parents. To reach this goal I?ve conducted a qualitative study, wherein I?ve interviewed eight parents with foreign backgrounds. The study is inspired by hermeneutics in its interpretation of results.From this study I can reach several conclusions.

The purpose of this study was to examine and illustrate whether employed social workers, working with supplementary benefits at a social service office, felt stressed. If so was the case, we wanted to investigate if this stress that they felt had any effect on their clients. This study was based on eight qualitative interviews, of which four was with social workers and four was with clients. For a better understanding of our results we used Karasek & Theorells demand-control-support model.The study reveals that the social workers do feel stressed, but they only do so in periods. They declare that they would like to have more time for their work assignments, the meetings with the clients in particulate.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

The amount of information stored on the internet grows daily and naturally the requirements on the systems used to search for and analyse information increases. As a part in meeting the raised requirements this study investigates if it is possible for a automatised text analysis system to distinguish certain groups and categories of words in a text, and more specifically investigate if it is possible to distinguish words with a high information value from words with a low information value. This is important to enable optimizations of systems for global surveillance and information retrieval. The study is carried out using word spaces, which are often used in text analysis to model language. The distributional character of certain categories of words is examined by studying the intrinsic dimensionality of the space, locally around different words.

This study examines if children in 5th grade experience any speech anxiety about speaking when everyone in the class will hear but while sitting down either by their desks or in a circle. I also want to find out how much the children speak; do boys or girls speak more than the other sex? Is there any difference in space of speech in the classroom, and if so is it connected to speech anxiety? Gender perspective is the theoretical outlook that this study has which is used to find out if there are any differences between boys and girls in the amount they talk in the classroom and the way the children themselves describe how it is to talk in the classroom. To find out if children in 5th grade experience any speech anxiety while speaking sitting down in everyday activities I interviewed six boys and six girls and to find out how much they spoke I observed the grade for a total of nine lessons. The result shows that some of the pupils do experience speech anxiety when sitting down and speaking so that everyone can.

On March 1, 2012, Google introduced its new privacy policy which is applicable to all Google services. This means that search history may be saved by Google indefinitely and may also be associated with the specific account during the first 18 months. We assume that few people read this policy and we have hypotheses that a deeper knowledge of the contents of the privacy policy affects how users perceive Google as a company and/or the usage of Google services. In this study, we have conducted surveys at the IT University of Gothenburg, to investigate how many participants that have read or possess some knowledge of the privacy policy. We have found that very few participants claim to have read the privacy policy.

The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..

The overall aim of this study was to examine if there were any difference between two different upper secondary schools with regard to the schools' work with the basic values. Our supposition was that if there were differences between the schools basic values work then it could be observed that the school that works more with the basic values has also more students expressed as a percentage who leave the school with final grades within four years. We have chosen to work with the qualitative method and made group interviews as well as individual interviews with six persons. We came to the conclusion that one of the schools worked with the basic values continuously while the other school had the intention to do it but according to our interpretation the school didn't do it. It also appeared that one of the schools had more students who finished school with final grades. The result that we have got showed that there is a difference between these two schools in the basic values work and that the school that worked with this continuously has also bigger amount of students with final grades. During work on this study we discovered other issues that we hope someone else can answer in the future..

Diabetes mellitus type 2 and chronic obstructive pulmonary diseases (COPD) are two of the most common diseases in the world and the amount are increasing. The treatments of these diseases are self care and a change of lifestyle. For this to be successful there is a need for the person to have knowledge about the diseases and a motivation for making changes in his or her lifestyle. Most of this information is given by the district nurse at the health centre. It is important to get a better knowledge of these persons experiences and how they used the information given to them.

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.

This essay is about a debate concerning the magazine Axess, feminism and antifeminism - in relation to a issue of Axess called To a new feminism. The theoretical foundation of this essay is Pierre Bourdieu and his field theories. The battles taking place in this particular field concerns the positioning of feminism and antifeminism in the way we culturally interpret these in our society. The essay shows that the magazine Axess (at least in the first edition of 2012) links feminism with a very prominent symbolic capital in a culture context. This discussion can at times seem confusing, and this is probably due to the fact that Bourdieus symbolic capital can be a very abstract concept. The journalist and author Maria Sveland writes about the development of a culture moving towards accepting antifeminism (and also xenophobia). She expresses the opinion that this, to a high degree, is due to actors in the culture domain with a big amount of trust in the public eye has moved towards expressing anti-feministic (and xenophobic) views.

The aim of this thesis is to discuss and analyse the American cotton subsidies? effect on the world market in general and developing countries in particular. The amount of U.S. subsidies is substantial compared to most other countries, but a great deal of the effect is due to the USA?s significant share of the market.

The weather has been extremely rainy the last summers in Sweden. Because of the rain, a lot of harvested straw has been lost since it was too wet to store. When the pig producers couldn?t get enough straw to use as bedding, an alternative was requested. Silage is a realistic alternative to straw but since silage often contains clover, it may not be suitable to use in pig production since clover is rich in phytoestrogens.
