Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

The market for eco-labelled products has developed rapidly from the early nineties in Sweden. There is a full variety of environmentally friendly products on the market today, and perhaps organic food is the most popular alternative. Eco-clothes have not reached the same amount of success as other eco-labelled products on the Swedish market. In this essay I will discuss and analyze which factors that have influenced green consumers attitude and behavior towards eco clothing. Four interviews with green consumers in Karlstad have been done in order to explore consumers attitude and behavior.

The purpose of this essay is to analyze and understand how people in different ways can take on the role as carriers of brands and understand what part they play in today?s society. Brands are everywhere today and the competitions are becoming harder and harder for the customers? attention and consumption, which is why I am curious of how an individual in a company?s frontline or a celebrity can help the success of a brand. The essay is based on a qualitative method where six interviews have been performed.

This study was performed to investigate the bacteriological quality of French cheeses made from raw milk. Fifty cheeses of this type were purchased from Swedish retail premises. The methods described by the Nordic Committee on Food Analysis (NMKL) were used to determine the number of Enterobacteriaceae, presumptive Escherichia coli, coagulase positive staphylococci and Listeria monocytogenes. In 32 cheeses (64%) the number of bacteria mentioned above exceeded the determined maximum value. Thirty samples (60%) showed high counts of Enterobacteriaceae.

First objective: To bring forward managers? perceptions of the underserved consumers in emerging markets. Second objective: To reveal what implications managers? perceptions of underserved consumers in emerging markets provide for branding in these markets. Our study indicates that managers? perceptions are still lacking consumer insights within five elements (value, loyalty, purchasing power, consumers and consumption).

 Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.

Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.

This thesis alsocovers other water refinement criteria.The work has been divided into three parts.

Med denna C-uppsats vill vi belysa bloggens betydelse för den unga bloggläsaren i Halmstad och Laholmskommun.  Genom tre teman som är konsumtion, livsstil och intrycksstyrning vill vi få en ökad förståelse för bloggens betydelse för den unga kvinnans självkänsla med fokus på bloggläsaren och bloggerskan.   Metodtriangulering var grunden för vår metodologiska utgångspunkt. Vi har tittat på skriftliga källor, tidigare forskning och tre bloggare som vi sedan intervjuat. Samt en enkätundersökning som utfördes bland elever på olika gymnasieskolor i Halmstad och Laholm, vi lämnade ut totalt 105 enkäter. För att ge undersökningen en bättre bild av hur läsaren upplever bloggen intervjuade vi även tre bloggläsare. Vi har kommit fram till att bloggen har stor betydelse för den unga kvinnans självkänsla och vi belyser detta ur en bredare kulturell synvinkel. .

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

Göbekli Tepe is an 11000 year old religious center where Totem has been exercised. It was raised by megalithic hunters and collectors that still during the construction lived in small-scaled mobile groups in order to find food and therefore should not have had time to raised costly stone monuments. The religious center consists of four enclosures with two T-pillars decorated with pictures of different animals and birds. Any dwellings have not been found. The place has been constructed by a well-organized elitist organization that has been capable of raising constructions in order to exercise their religion in a way we did not thought was possible such a long time ago. Analysis and findings from the near east existing from this time shows however that social changes happen in the communities around the region. Can archeological finding from the excavations on the religious center give any answer or clue regarding how man came to develop from hunter and collector to farmer? Do the findings reveal that the religion has changed Mans way to think and organize so that she was prepared to introduce the agriculture that occurs? The aim of thesis is to clarify whether Göbekli Tepe has played any role in the complex origin of agriculture..

Purpose: The purpose of this study is to investigate the effect and potential of a non-styled home reportage, and how they influence and inspire to promote individual creativity.Method: I have used a qualitative analysis to be able to create a deep understanding. This is based on three interviews with women in age 22-27, which have a dedicated interest in interior design. I have also sent questionnaires to two persons who run interior design blogs.Conclusions: My analysis shows that the non-styled home reportage is the start of an inspirational process that is beyond consumption and status objects. It promotes individual creativity and willingness to create, based on personnel taste. The essay highlights the importance that the individual critically examines the aesthetics of interior design as presented in diverse media.

The purpose of this paper was to look at the perception of self-determination for adults with intellectual disabilities from their perspective. We wanted to examine the experience of the space available for self-determination in some key areas of life, and how their own thoughts and ideas have been addressed by others. Through interviews with six people with intellectual disabilities, we have found that a single definition of self-determination is elusive. The key seems to be that you get the opportunity to do what you want, to have your voice heard and to receive and take responsibility. The space for self-determination is perceived by respondents as both large and small.

The aim of this Master?s thesis is to study the information needs of the homeless. The main focus is to investigate what kind of information needs that are to be found among the homeless and also how information is exchanged and shared by the group. Another aspect of our study includes the sources that are used to fulfil these information needs. The homeless use of the library, as one of these sources, is also examined.
