The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

The aim of our study is to ascertain whether a hanging suspension fluorescentlamp for a private home environment is going to be attractive for a largeaudience. We want to open up for new uses of fluorescent lamps as lightsources.The main approach in this work is how to design a fixture with fluorescentlamps as a light source that will meet the requirements and requests of thehome environment could look like. At the same time we want to make a newimpression of how a fluorescent light source.Primarily we used a quantitative method, but this was rejected after a pilotstudy. Instead we used a qualitatively based method in the sense that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately.

This thesis presents my work at the company Fatshark AB in Stockholm. My supervisor Rikard Blomberg, who works as a chief technology officer at Fatshark and is one of the owners of the company, explained that they had experienced weaknesses in the methodology used when developing heads up displays (HUD) for their games. In the latest production, Lead  and Gold, the HUD had been redesigned a number of times, becoming an unnecessarily big expense due to the number of work hours invested. In modern software development, an iterative workflow is commonly encouraged. Despite this fact, the work efficiency could likely be increased by setting up guidelines as a help in the process of developing HUDs and reviewing the solutions.

In this essay I analyse three of my own texts included in an unpublished collection entitled till Narcissus' minne. Genres are discussed and a detailed study of how the writing process has progressed is done. The essay does not follow any specific literary or scholarly method of analysis, but to some extent the sphere of interpretation is explored. By associative interpretation the special logic of dreaming, the activity of the unconsciousness and the expansive accessibility of the memories, which characterize the texts, is traced. These structural features open a link to the way of psychoanalytical interpretation, but the essay does not strive for a complete account.

There is two dairy farms in Sweden with ability to be opened on both long sides, one outside Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results or not enough literature about natural ventilation and especially on this kind of air inlet, makes my tests very interesting not only on Alnarp, but among other companies. I would like to find out if there is any air movements direct on the cows, how high/low temperature, air humidity, light intensity and noise standard inside the barn. Does Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could this system become the new dairy barn instead of the conventional barns in Sweden? I am going to focus on the animals environment, after all they are the one who is going to spend the most of the time in the barn. I used five electrical loggers distributed inside the barn to measure the temperature and one of the loggers measured the air humidity, every 15th minute. One logger were placed on the outside which measured both temperature and air humidity.

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.

Företagens ökade nyttjande av jordens resurser och dess belastning på jordens biologiska processer, leder idag till ohållbara försörjningsflöden. Företagens beroendeställning till dessa ostabila flöden riskerar att hota företagens fortsatta existens. Med denna insikt genomgår samhället en hållbarhetsförändring med ökat intresse för det egna ansvarstagandet. Vad innebär ett företags ansvarstagande och hur ska detta ansvarstagande tas? Att lyfta in icke-finansiella aspekter i företagets arbetsprocess är ett populärt svar på denna fråga idag, vilken ofta belyser företagets hållbara ansvarstagande inom den egna verksamheten.Det kan ifrågasättas om företag är tillräckligt ansvarstagande genom detta agerande, då ovanstående tankesätt inte inkluderar den miljöpåverkan som företaget för orsak till utanför den egna verksamheten.

The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.

This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..

There is a settled stereotype for women and men which give them different possibilities in our society. The schools, which are one of the most important sources of knowledge, have a great possibility to influence. This is the reason why we are interested in how the schools are working with a project, which we will call X henceforth. What was the purpose with the project and what does it contain? What is missing in the former education, since the project was started? Are there any obstacles or prerequisite in the design of the project or in the school teaching on the basis of X? We have done interviews in the gathering of empirical material to find out all the answers to our questions.

In this paper I have examined how the structure of society affects the characters in the movies of Gus Van Sant, and what there is that characterizes Van Sant as an auteur. I have also looked at the thematics and how the characters develop throughout from his first movie Mala Noche (US 1985) until one of his latest Milk (US 2008). Van Sant is open with his Homosexuality and those perspectives are of major importance for this study. He presents how his characters try to live a normal life in a society that is not made for them. I have chosen to analyze five different movies.

The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything. The surveys were distributed to various local companies. After having received a lot of answers, I concluded that the clear priority was the most positive feature of scrum and the most negative was that it was difficult to get the rest of the organization to understand scrum, which creates problems. Both high school class and local companies believe in scrum?s future, even if they think scrum will be partially modified to adapt to the software-development in the future. According to the survey responses, the most important to get the projects to be successful both now and in the future is that everyone who work with scrum is right educated..

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.
