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.

Purpose: The purpose of this study is to seek understanding, describe and analyse how auditors practically reassure and maintain their independence towards clients.Methodology: The study is conducted with a qualitative method with a deductive approach. The study is based on interviews with both experienced and recently graduated auditors.Conclusion: Our empirical results show that there are economical incentives that contradict the requirements to fulfil the auditor?s independence. The conclusion is that the media view is narrow and biased. Furthermore the auditors agree that an acceptable level of comfort is achieved by offering a high value, being a part of a large network of professionals and the ability to set materiality and evaluate risks. .

Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.

Background: In the martial art of Muay Thai, techniques are used with hands, elbows, knees and kicks. The contestants are divided into different weight classes and experience levels. The Swedish martial arts association has decided that techniques with elbow are not allowed in B-class. Why is it so?Objective: The aim of this study was to investigate whether the martial arts delegation decision to restrict techniques with elbows to the head in the B-class is justified.

Detta examensarbete handlar om hur datatrafik över en satellitlänk kan optimeras för att minska laddningstider och överförd datamängd. Syftet med studien är att undersöka i vilken omfattning datatrafik mellan fartyg och land via satellitlänk kan styras så att trafiken blir effektivare. Genom att använda DNS-mellanlagring, mellanlagring av webbsidor samt annonsblockering med pfSense som plattform har examensarbetet utfört experiment emot olika hemsidor och mätt laddningstid samt överförd datamängd. Resultatet visade att det fanns stora möjligheter att optimera nätverkstrafiken och de uppmätta resultaten visade på en minskning av datamängden med 94% och laddningstiderna med 67%..

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

Schyman?s legs in Let?s Dance as a communication strategy- a case study of ?Feministiskt initiativ? in the election campaign 2010.(Schymans ben i Let?s Dance som kommunikationsstrategi, en fallstudie om Feministiskt initiativ i valkampanjen 2010).Author: Joanna Morell, Tutor: Ann-Marie Morhed2009 was the first time where Swedish political parties were entitled to have TV- commercials, another sign of political communication taking one step closer to the strategic marketing communication. A type of communication that also is expensive.The Swedish political party Feministiskt initiativ (Fi) have existed since 2005 and is not yet a part of the Swedish parliament. They have not been entitled to the economic support that is given to Swedish parties with more than 2,5 percent of the votes in the last two elections. As a result Fi is completely dependent on economic contributions.

Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

The purpose of this thesis is to present and describe which criteria, according to the systemfamily Configuration Management, should be met when developing a CM-tool to handlemigration data.ACT is a tool developed by Microsoft to gather information about, analyze, test and mitigateapplications in a network when migrating the IT-infrastructure of an organization to a newoperating system. The organization that is being studied wants to present the data about theanalyzed applications in such a way, that a customer can choose what to mitigate and migrate.The goal is therefore to develop a prototype (CM-tool) that will present this data.The study has shown that ACT lacks certain requirements stated by the organization when itcomes to presentation. But when it comes to the rest of the functions, ACT performs as expected.The investigation resulted in specifications and technical solution for the new CM-tool. CMcriteriafor migration data was put forth and parts of the prototype were also developed..

The essay depicts the opposite views of the director and an actor during the filming of a specific scene in a feature film. The actor feels that he is not being listened to. This leads to unforeseen consequences for the director, as the actor no longer wishes to take part in the marketing of the film prior to its opening night. Everything is seen from the director?s point of view, she is working in a film world dominated by men.Questions are being asked if the director?s instructions are clear enough or if the actor, fearing getting lost, is mixing up his own feelings with those of the character he is portraying? What happens to the collaboration and how does it affect the rest of the team and the completion of the production? The director is also the producer.

The functional connection between the building and the streetscape affects the city and its attractiveness. Stores located in shopping malls with their entrances facing internal walkways, creates segregation between the mall and the streetscape. This segregation implies that the shopping mall loses some of its attractiveness, which may result in a so-called Greyfield mall. The expression Greyfield mall is used for shopping malls that have lost its visitors. Competition from new modern malls and a lack of investments are examples of factors that influence the development of Greyfiled malls.
