Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

Stress är en växande folksjukdom i Sverige och en grupp som kan vara särskilt utsatta för kumulativ stress är soldater som ligger i beredskap. Vi har från våra förfäder ärvt en förmåga att vid fara reagera med en stressreaktion som en förberedelse för kamp eller flykt, också med en reaktion som gör att vi kan bli handlingsförlamade. Om dessa reaktioner upprepas gång på gång utan att kroppen får utlopp för den höjda energinivån ökar slitaget på kroppen. Stresshormoner samlas i kroppen och byggs på och kan under en längre tidsperiod leda till kumulativ stress. Om detta fortsätter kan det leda till ett utmattningssyndrom.Syftet med uppsatsen är att kartlägga hur soldater som ligger i beredskap upplever sin allmänna hälsa och den stress som de dagligen utsätts för.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context. I have explored different light sources and compared them to each other and given a short description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms. I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.

The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

The purpose of this paper is to evaluate the work situation for temporary workers within the field of journalism. During the past decade, influential external forces such as commercialization, new technologies and increased competition have brought great changes within the industry. As a result, employers value flexibility of manpower, not least to reduce cost, where the flexible employee is usually leased by the media company from a manpower company. Today it is a normal practice with manpower companies and this way of hourly paid form of employment. Although the temporary worker can sometimes benefit from this kind of employment, there are also significant setbacks like job insecurity.

SVENSKA: Vårt kandidatarbete gick ut på att ta reda på om det var möjligt att utveckla ett kort spel i hög teknisk kvalitet och ändå skapa ett djupt intryck på spelaren. Under projektets gång utvecklade vi, med hjälp av UDK (Unreal Development Kit), ett skräckspel i 3D till PC vid namn The Horror at MS Aurora. För att erhålla den höga tekniska kvaliteten som vi var ute efter användes metoder som räknas som standard för stora speltitlar på marknaden: Animationer spelades in med Motion Capture och musiken skrevs med en full symfoniorkester i åtanke. Innan produktionsfasen tog vid gick alla gruppmedlemmarna igenom en research-fas, där var och en satte sig in i de områden som skulle komma att vara aktuella under produktionen (d.v.s. hur UDK fungerar, musikteori och orkestrationsteknik, hur man arbetar med Motion Capture-data o.s.v.).

I have written an experiential essay about my role as a preschool director and the important work decisions that I face. What is best for the child? That is something that I think is important to take into consideration.In the narrative, I describe how an induction occurs at my preschool. We use an "old" tried and true method which spans two to three weeks, which I believe is best for children under the age of two. They need to first connect withone educator who they are comfortable with before they are secure enough to play and explore the environment of the preschool.In recent years, another method has emerged which is shorter and which has quickly became popular in many preschools.

This thesis aims to study brand change, which can be of interest since a brand during its lifetime can be expected to meet a lifecycle consisting of five phases; innovation, introduction, growth, maturity and recession. In order to avoid the recession phase and the sales decline that follows there is a need for a change of the brand.In order to study brand change, theoretical framework is compared to two real world cases that have gone through an active change.The conceptions of positioning, repositioning and revitalization are clarified. Positioning deals with how brands are located in customer?s minds as well as on the real market. Repositioning implies a change of the current position and is also often a move towards a new market segment.

Denna uppsats undersöker hur kvinnor och män i olika åldersgrupper förhåller sig till Flashapplikationer utifrån deras uppfattning om färg och form. Deltagarna som består av skolungdomar, nyexaminerade studenter och pensionärer har genom en enkät och en semistrukturerad intervjuform fått redogöra för sina intryck av Santa Marias, Eccos och Indiskas webbplatser. Undersökningsdeltagarna identifierar Flashelementen genom deras rörelser. Deltagarna vill välja om de ska se animationer och andra applikationer skapade i Flash för att inte tappa koncentrationen från övrigt innehåll. Studenterna i undersökningen har en mer kritisk hållning till färgval, formgivning och användandet av Flash än övriga.

VikingGenetics is one of the world's largest breeding companies. 2008 was launched two new products, X-Vik and GenVik. Now VikingGenetics want to get information about the effects of the marketing. We have investigated the differences in knowledge and use of the products between different livestock associations, size of herd and farmers' breeding interests. The method used was by sending out a questionnaire by mail.

The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.

The main purpose of this study was to examine own and social influence on perfectionismwith individual athletes. The participants (n= 96) of this study represented ten different sportsand their ages was between 15 and 44. An interview with four of the participant wasconducted. The instruments used for this study was the Positive and Negative PerfectionismScale (Terry-Short et al., 1995) and for the interviews questions was based on own and socialinfluence. The results showed that there was a relationship between positive perfectionismand own influence, negative perfectionism and own influence, negative perfectionism andsocial influence.
