The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

AbstractAimThe aim of the pilot study was to compare short- and long-term effects from group exercise in water with land-based exercise on pain at rest and pain with movement, along with the effects on function in daily life and practice of sports and leisure activities in patients with knee osteoarthritis. The aims were: Is there a difference in short- and long-term effects on pain intensity at rest and pain with movement after exercise in water or land in patients with knee osteoarthritis? Is there a correlation between the degree of pain intensity at rest and with movement, respectively and long-term effects from the two different exercises on function in daily life and practice of sports and leisure? MethodThe study was a randomized intervention study without a control group. Twenty patients with radiographic knee osteoarthritis were under a total of eight weeks treated with either land- or water-based exercise lead by a physiotherapist. The patients rated pain intensity at rest and with movement on a numerical rating scale (NRS) before and after the first training session, before and after the eighth training session, before and after the fifteenth training session and before the last and sixteenth training session.

In order to accomplish that a construction is correctly built, it is critical to obtain a well functioning control mechanism throughout the project. The way to enable this is not by having an independent inspector constantly at your side. Today it is praxis to use check lists and have people responsible of quality to make sure that these are followed. This is where discretionary inspections play their part. These among others are documents needed to com-plete the check list.

UN is a non-governmental organization which should promote gender equality within the organization. It is an organization which is based on human rights and claims that in order to solve the problem of poverty, famine and development we need to promote women?s status. In Sweden there is a strong tradition of gender balanced representation at the governmental level and this perspective raise the question if there is a spill-over effect to the civil society as in the case of a non-governmental organization. This makes it interesting to look at if a non-governmental organization which is not under state control work for gender equality within their own organization.

Spectacular buildings and categorized districts are becoming more common elements in cities. In many cases, they are the result of city branding, which means choosing a city image and dealing with it like a brand to profile and compete against other cities. This essay study what impact on and roll in urban planning the trend might have. The first part relies on literary studies and describes what has been written about city branding. The globalization, the experience economy, urban management, urbanization and the theory of the creative class are pointed out as driving forces of the popularity and the spread of city branding.

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.

Syftet med denna uppsats är att undersöka den första månadens rapportering kring försvinnandet av Madeleine McCann och på så sätt få en bild av vilka faktorer som skapade ett så stort publikt och medialt intresse för just detta fall. För att kunna svara på detta ställs tre övergripande frågor ? vilka aspekter lyfter medierna fram i rapporteringen, hur bidrar dramaturgisk bearbetning till att forma rapporteringen samt vilken betydelse får huvudaktörer i rapporteringen.Undersökningen görs genom en kvalitativ analys av återkommande teman i rapporteringen. Denna kompletteras med en kvantitativ innehållsanalys för att få fram statistik på hur mycket utrymme visa aspekter får samt vilka benämningar som görs vid porträtteringen av Madeleine McCann.Det undersökta materialet består av artiklar från tidsperioden 5 maj 2007 till och med den 7 juni 2007 i Aftonbladet, Expressen och Dagens Nyheter.De teoretiska ramverk uppsatsen utgår ifrån är teorier om socialkonstruktivism, nyhetsvärde, medielogik och narrativ berättande.Resultatet visade att den främsta faktorn till att fallet uppmärksammades är genom den personifiering som gjordes av Madeleine McCann och hennes föräldrar. Personifieringen leder till att rapporteringen kan konstrueras till en nyhetsberättelse.

Since the beginning of the internet the criminal world has used the medium as a platform for operation.This dark web is a domain where illegal sites are flourishing due to the possibilities offered by newtechnology. Net-based criminal activity is a challenge for society as it uses hard proof technologicalsafety measures to avoid the law. Silk Road is the most prominent example, an online illicitmarketplace where drugs and illegal substances are being traded based on conventional e-commerceconcepts. This paper argues for trust as an important factor for the survival of illicit online trade andapplies existing theories on e-commerce and virtual communities. To identify patterns of trust andcommon trust-based issues among Silk Road users, a netnographic study was conducted on the site?sdiscussion forum.

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

Aim and questionsThe aim of our study was to increase knowledge about successful school managers' views on teachers' mental health and their own work regarding this subject.In what ways do the school manager work preventive with measures on teachers' mental health? How does leadership affects teachers' mental health? What factors create mental health among teachers? MethodIn order to answer the questions, we have chosen to use semi-structured interviews. To get in touch with schools that have been successful with their work with the teacher's mental health, we have made a targeted step wise sample where we contacted the primary managers of six randomly selected municipalities in Stockholms län. In total six school managers have been interviewed. The empiric data were thematized and analyzed based on the demand-control-support model. ResultsAll the interviewed school managers agreed to that the concept of mental health is about feeling good, about balance in life and to feel safe.

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.

Lean is one of the recent years most popular methods for organizations to use in order to increase efficiency, productivity and quality. Despite Lean's increased popularity, Lean is still difficult to define and can be explained and described in different ways. Previous studies have also shown that Lean is difficult to implement and challenging to maintain successfully. Knowledge of Lean is viewed as a necessity in the implementation of Lean, which leads to that organizations often chooses to bring in this knowledge through external consultants or other experts in order to implement Lean in their organization. Thus, it is interesting to examine the consultants view on Lean and the implementation process of Lean.
