Applications for mobile devices, also known as apps, are today the backbone of a huge market where the company Apple is one of the key players. Apple develops, among other things, handheld electronic devices, which are powered by the operating system iOS. Through iOS, millions of customers get access to Apple?s App Store.During a period of two months, an app in the form of a game has been developed for iOS in the programming language Objective-C. The user of the app is presented intuitive menus and interactive graphical objects that seemingly obey physical laws.

Sahlgrenska Academyat University of GothenburgDepartment Of Internal Medicine And Clinical NutritionAbstractTitle: The effect of CLA on body weight and body fat amongst overweight and obese.Author: Sierra De Goldsmith and Amanda EgebergSupervisor: Frode SlindeExaminer: Anna WinkvistProgram: Dietician study program 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 12, 2012Background: Overweight and obesity represents a global problem as it is accompanied by an accumulation of body fat which increases the risk of developing diseases such as diabetes type 2, insulin resistance, cardio vascular diseases and certain types of cancer. Moreover, the prevalence is increasing worldwide. Many consider it difficult to reach a normal weight using only methods such as changing dietary- and exercise habits, this creating a market for products that facilitate weight loss and loss of body fat. The supplement of conjugated linoleic acid (CLA) is such a product. In animal studies, CLA has demonstrated a reduction in both body fat and weight.

The purpose of this Master thesis is to examine theinformation use and information seeking behaviour amongpersons who actively work with information. For this study,interviews have been conducted with a group of six personswho work with information in information intensiveorganizations. The aim is to answer the following questions:What kind of information is connected to the respondents?work tasks? What is the purpose of their search forinformation? Which information sources do they use and whatkind of information sources do they demand? The theoreticalframework consists mainly of Wilsons information needs andinformation seeking model.The results of this study show that none of the respondentshad any strategic model for their work with information. Theinformation that the respondents were searching for is ofdifferent content and depends on the organization in which therespondent operates.

I det här arbetet har algoritmen Simulated Annealing undersökts med avseende på dess möjlig att användas för att minimera av kostnaden för ett singelfrekvensnät för digital tv. Undersökningen är gjord genom att simulera ett antal testfall för att utreda hur olika ingående optimeringsparametrar inverkar på slutresultatet. Alla försök har genomförts i ett egenkonstruerat simuleringsverktyg, gjort i Matlab. En jämförelse av resultaten för två olika sätt att hantera täckningskraven har också gjorts, Simulated Annealing med- respektive utan straff metod. Alla genomförda försök har genererat en betydande kostnadssänkning jämfört med startkonfigurationen.

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

The purpose of this legal dogmatic Bachelor Thesis is to define the legal definition of ?a rescue service? and illustrate the division of responsibilities between national authorities and the municipalities with regards to the execution of emergency response operations.?A rescue service? means the emergency response actions that national and municipal authorities are legally obliged to provide to prevent or minimise injury to people and damage to property or the environment when emergencies occur or seem imminent. In the following cases a national authority is responsible for providing the requisite rescue service:1. Search and rescue (air) ? the Swedish Civil Aviation Authority is the responsible authority;2.

This Master?s thesis is the first to quantitatively study the prevalence of library anxiety at a Swedish university. Library anxiety is a concept describing the negative feelings students can experience when using the library. The study was conducted using web questionnaires sent out to 512 students at Växjö university. 38 % responded and the results were analysed with the help of, amongst other methods, correlation studies.

The purpose of this thesis is to discuss the possibilities of, and interest in, a digital download service at the music departments of the libraries. I chose to conduct my study at the city library of Gothenburg. I studied the legal download services that exist today and I did a statistical survey among the users of the music department, followed up by interviews to see how they took to the idea. From the inquiry I learned that a majority of the users was negative to having a digital service replacing the physical department, although a majority was positive to try a digital service. I also used the inquiry to compare the reasons for downloading music to the reasons for borrowing records from the library, but there was no significant difference.

The purpose of this thesis is to examine the usability of the Umeå University library catalogue Album. The aim is to evaluate the catalogue in order to establish if there are any problems that could be solved by modifying the catalogue. The following questions are answered: How should a good catalogue be designed? Which problems are common when using a library catalogue? Is Album user friendly? Are there any problems that occur when using Album and how can the catalogue be changed to avoid the problems? To answer these questions I have performed a usability test in which five persons, all students, got to carry out twenty tasks in the catalogue and talk about what they were doing and thinking while doing the test. This method is a usability method called Think Aloud.

Syftet med det här arbetet har varit att välja ut och integrera en lämplig fysikmotor med öppen källkod i simuleringsprogramvaran EWSim på Totalförsvarets Forskningsinstitut (FOI). EWSim är ett ramverk för duellsimulering i olika telekrigsscenarier. Teorin bakom fysikmotorer och några vanliga tekniker för fysiksimulering har beskrivits kortfattat. Tre fysikmotorer har presenterats och utvärderats med avseende på lämplighet för integrering i EWSim.Fysikmotorn Bullet valdes ut och integrerades i simuleringsprogramvaran. En av de huvudsakliga slutsatserna av arbetet är att fysikmotorer som Bullet mest kan bidra med ökad visuell realism i EWSim.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

 AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.

The main purpose of this study is to analyse how the main themes of alienation and the search for identity is portrayed by Swedish author Inger Edelfeldt. I have applied the theories of Rita Felski concerning feminist novels of self-discovery, in which the development of the female identity is the main question. As Edelfeldt?s writing consists of literature for the young as well as adults, I have included material from both of these genres. I have also taken use of Ulla Lundqvists theories about Swedish juvenile books when examining aspects of the main character?s feelings of alienation and identity searching.The results of my analysis show that the reading of my material as feminist novels of self-discovery has revealed pervading charachteristics of alienation, love, friendship and psychological development.
