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 thesis describes how social work language practice circulates around the implementation process of an evidence based structured assessment tool – Savry. The purpose is to examine and understand the social workers language practice in a working group that uses this structured assessment tool in their work with youth. The purpose is also to look for dimensions of identity in terms of discourse. The ontological viewpoint is post-structuralism where language is in focus. The theoretical framework is discourse theory based upon the work of Ernesto Laclau and Chantal Mouffe.

The purpose of this Bachelor thesis in religious history, is to examine how religion reflects in the artwork and in the architecture in old and new kingdom in ancient Egypt, also to explore how book of the death reflects in the artwork. By means of using the visual culture theory, I have analyzing the selected pice of art with myths and texts from the ancient religion, to been able to come the the results of this study. It was know that religion had a major part in the artwork of ancient Egypt, especially in the new kingdom. In the old kingdom pharaoh generally was in the centre of the art, but also the gods. In new kingdom they started to illustrate texts and myths from book of the death, and the life after death was of great matter.

The purpose of our qualitative study is to investigate how the caretakers, in the elderly care,interpret and manage the issue of alcohol problems in elderly people. We have beenperforming semi-structured interviews on 9 people, on different levels in the elderly care.There were 3 elderly care managers, 1 nurse, 1 assistance administrator and 4 auxiliarynurses, who all, at some level, work with alcohol problems in elderly people. Thoseinterviews were performed singularly, with one exception: we interviewed an elderly caremanager and her 2 auxiliary nurses at the same time. To analyse our empirics, we have usedthe theories of Power and Ageism. Our study shows that the auxiliary nurses, who are theones who must deal with these problems, have great difficulties to perform their work becausethey have no qualified knowledge about alcohol problems.

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

News value is an essential part of which event media chooses to report about. Political events consider to bee news with potentional large value. Media has an enormous power and possibility to create news and construct there own reality and where the readers is given a false expression of what really happened. Today the media must show profit and that indirect affects how the media choose to describe political events. In the Kenya case is it therefore possible to draw the conclusion that the two news paper has different construction of the political event in Kenya.

The purpose of current paper is to identify the differences (ifany) between Swedish and Turkish consumers in terms ofproduct design perception and to identify the differences toproduct design in relating the four dimensions / characteristics:1.Aesthetical attractiveness, 2.Functionality, 3.Value and4.Quality.The findings of the study indicate the existence of a universal perception of design. Despite the culturally different countries that are examined the empirical material consistently display similarities between the two countries. Both the quantitative and qualitative data point to a very similar perception in terms of design. The possibilities of global design are discussed for companies as well as managerial implications and future research..

Research has shown that immigrants in the Swedish society often, when seeking jobs, don?t get the same opportunities as the rest of the population. This thesis is a qualitative research that examines the problematic situation of unemployment among immigrants in the municipality of Finspång. The purpose of this study is to analyze how civil servants in Finspång apprehend and describe the labor market problems surrounding the immigrant groups that live in the municipality of Finspång. The empirical material is build upon seven qualitative interviews with eight civil servants working in Finspång.

In this essay I have studied how the kid?s school start are described in picture books. The studied questions are: How the school is described in these selected picture books; what feeling does the main character have into the school start; how the teachers are described in this selected picture books and how are the power relationship described in these selected picture books?The method I have chosen for this essay is a discourse analysis of seven selected picture books with the meaning of starting school. All books studied are written during the 1990 and forward.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

This essay is a comparative empirical study of ethnic integration mainly of the Russian-speaking minorities in the three Baltic states (Estonia, Latvia and Lithuania) in a post-communism setting. As Lithuania has a Polish minority that is as large as the Russian-speaking, they too shall be included in the study but not as thoroughly as the Russian-speaking minority. Thus the problem is: to what degree are the ethnic minorities integrated with the titular nations in Estonia, Latvia and Lithuania? In order to study ethnic integration I have set up a theoretical framework largely based on Weiner?s theory of integration. The theoretical framework focuses on three dimensions: Citizenship, Identity and Segregation.

Background: It has been shown that EDI can yield positive effects within companies. Which effects are possible for a company to direct assign to the introduction of EDI and is it possible to estimate the total effect.Purpose: The purpose of this study is to estimate and analyze the effects of using EDI in electronic business. We also want to contribute with a model for measure and estimate the effects of EDI.Accomplishment: We have studied literature concering EDI and realized a preliminary studie in form of interviews with experts to establish deeper knowledge of EDI. We have also tried to estimate the effects obtained in companies in three different businesses, power, government and transport industry.Result: To obtain as good effects as possible it is important that the co- oporation is built on trust and engagement. Before implementing the EDI-system a thorough overhaul of the processes in the company should be done, involving both the top managers and the staff.

The purpose of the study is that based on focus groups with personal assistants understand how self-determination and participation, expresses itself in work with the users. The study has a focus on the concepts of power and help and social citizenship in the context of self-determination and participation. We are interested to explore how personal assistants reason and argue about different design cases and situations related to self-determination and participation in the relationship with the users. For this study we have used a qualitative method and to collect our data we have used focus groups and different design cases (vignettes). To analyze our data we used the theory about power and help and the theory about social citizenship.

We are heading towards a huge switch of how energy is produced with fossil fuels being replaced by renewable energy sources. It is not difficult to replace the energy you use in the house and there is no need for futuristic technology. There are already many established products on the market such as high efficiency vacuum solar collectors, heat pumps & small wind power stations that can supply the energy being used in a house. The company Sol & Energiteknik SE AB in Huskvarna has many different products which can reduce the need for an outside energy distributor. An average house in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity.

Användandet av betong som ersättare för stål vid produktionen av vindkraftverkstorn har ökat den senaste tiden. Betongtorn är betydligt billigare än ståltorn men problem som sprickbildningar, frostsprängningar och följaktligen armeringskorrosion har uppstått bl a på grund av vibrationer från rotorn. I fundamentet i vindkraftverk kan ovan nämnda problem också uppstå och det uppfyller således inte alltid funktionskraven. Det här examensarbetet undersöker möjligheten att eliminera dessa problem genom att använda en sorts högpresterande betong kallad UHPC 2.2 med syntetfiberarmeringen, STRUX. Jämförelser mellan tidigare empiri om högpresterande betong och laborativa tester på UHPC 2.2 visar att den senare är beständigare och ger möjligheter till en större sprickfrihet.
