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.

This project started when LIC Audio AB wanted help with development of a hearing aid for public rooms. The problem is that a lot of people suffer from some sort of hearing impairment. In places with a lot of people and background noise the problem becomes bigger and the sound seems to flow together. During the project we found the solution for the problem in the shape of a headphone. The headphone receives a signal from a preinstalled hearing loop.

Rural development in Southeast Sweden- three different views and their consequences for the agrarian landscapeThis paper deals with the future for the rural areas of the southeast province of Östergötland, Sweden. The aim is to unveil, analyse and compare different views on rural development and their consequences for the agrarian landscape. Three views are considered, namely that of the different levels of Governments and their departments, that of the farmers and landowners and, finaly, that of the inhabitants of the rural areas.Differences in the views upon rural development is reflected in differences in the ways of thinking of landscapes. Is the open, and actively cultivated, landscape the ideal for all? Who is to decide what needs or ought to be done to achieve certain desired values and/or goals ? and who pays for it? The one thing that is, and should be, clear from the beginning is that all development, whether positive or negative in an area, bears consequences for the landscape.

Could patterns change the way we as consumers feel about a product as it ages and wears down? Why do some products increase their value as they are being worn downand others do not? Could the same affection that increases with your favourite jeans or an old, worn down, scratched and beautiful wooden furniture, be applied on otherproducts with different ability?s and history?The goal was to explore patterns and beautiful aging in products to increase the consumers desire to keep the well used product a little bit longer. Not to prolong the products ?lifetime? from brand new till it?s no longer inhabit their main function, but at that precise momentwhen you as a consumer decides to through it away in favour for a new, updated version. To buy ?new and fresh?.Patterns with different expressions, colouring and size, were explored that increase the value of a product which in this project contained handles and varies of surfaces on casseroles, frying pans, whisks, cutlery etc.

Almost half of the population in Sweden suffers from obesity and the cases of eating disorders are increasing. We are exposed daily to the belief that losing weight will make us happier and it will just be through this particular diet. Even if it has been proven that short dieting plans like ?lose 20 pounds in one month? doesn?t give a long-term result, society continues to buy into the idea that they do.Every day 16000 placards are placed around us in Sweden with loud yellow colors and big black letters which make them almost impossible to avoid. Their main purpose is to attract and get as many people as possible to buy single copies.This essay deals with several questions: How diet tips figures on placards and how this has developed through years.

Att ta fram en ny bilmodell är ett tidskrävande och omfattande arbete där många olika kunskapsområden måste samspela. En del i utvecklingsprocessen som får allt större betydelse är designarbetet. Om bilens utförande och design inte tilltalar konsumenterna innebär detta låga försäljningssiffror och därmed förlorade intäkter för företaget.Det huvudsakliga syftet med detta arbete är att grundligt undersöka om och hur CAD-programmet Catia V5 med modulen Imagine & Shape (IMA) skulle kunna användas på Volvo Car Corporations designavdelning (PVS). Syftet är också att granska vad en implementering av Catia V5 med IMA-modulen skulle innebära för produktutvecklingsprocessen, samt att undersöka vilka som skulle kunna använda sig av programmet. För att undersöka hur Catia V5:s IMA-modul skulle kunna fungera på PVS har vi i samarbete med designstuderande Pontus Ny modellerat en konceptbil, komplett med exteriör, instrumentpanel, mittkonsol, ratt, stolar, baksäte, fälgar och hjul.

The dog (Canis lupus familiaris) is the first species ever domesticated. They can develop a close bond towards other dogs, almost like a relationship among siblings, which can be a high valuable resource for good relations and cooperation?s. Dominance in dogs is sometimes used to explain undesired behaviors and explained as a personality trait. Dominance though, is not a trait in a dog or a source for undesired behaviors, but can rather be explained as a relationship between individuals, were one of them receives more submissive signals from the other.

More than 90 % of all business activity in the world market consists of small and midsized companies today. Recent studies have shown that there has been an increase in small companies? certification to ISO's management standards. Smaller organizations tend to have more limited amounts of resources at their disposal than larger ones. This can result in difficulties during the implementation process of ISO 9001.

The purpose of this Master thesis is to examine whether the term elasticity is relevant and functional to apply to public library organisations. Another aim of the thesis is to relate the term elasticity to public library organisations in a network society. Sociologist Manuel Castells provide the theoretical framework on the network society. Three investigations (meant to complement each other) in two Swedish public libraries seek to give answers to these questions.To be able to examine which areas of public library activity are elastic, I make a rough definition of what public library organisations consist of ? nine activity fields are identified using IFLA?s guidelines in combination with Swedish law of public libraries.

The aim of the present study was to estimate the correlation between Euro NCAP pedestrian rating scores and injury outcome in real-life car to pedestrian crashes, with special focus on long-term disability. The study also surveyed most frequently injured body regions and risk differences for specific elements of pedestrians hit by cars. Another aim was to determine whether Brake Assist systems affect the injury outcome in real-life car to pedestrian crashes and to estimate the effect in injury reduction of a high Euro NCAP ranking score combined with Brake Assist.In the current study, the Euro NCAP pedestrian scoring was compared with the real-life outcome in pedestrian crashes that occurred in Sweden 2003-2010. The real-life crash data was obtained from the data acquisition system STRADA, which combines police records and hospital admission data. The medical data consisted of International Statistical Classification of Diseases and Related Health Problems (ICD) diagnoses and Abbreviated Injury Scale (AIS) scoring.

The thesis focus on how organizations can improve the ability of absorbing coworkers ideas in purpose of gaining long term competitive advantage through innovations. The study was conducted at IKEA AB where a campaign to collect coworkers ideas was a big success given the quantity of ideas collected. This fact allows a comparative analysis of idea management in the shape of campaigns and in comparison, idea management in the everyday line-organization.The analysis show that fundamental factors for innovative environments such as organizational climate, culture and leadership perceives auspiciously by the respondents. However, lack of infrastructure such as systems and processes hinders coworkers ambitions to contribute with ideas.An important issue in idea management is the treatment of incentives for innovation. Results of the study show that the ?soft? incentives ?feedback, encouragement and attention have a higher impact in coworkers willingness to the contribution of ideas than for instance monetary rewards..

Preschool is a place that is continually undergoing change at a rapid pace and developing the skills of our educators is essential for their ability to keep up with these changes. Guidance conversations can be used as a vital tool for the educators competence development.The purpose of this essay is to investigate how educators, special educators and preschool principals think and reason about the use of guidance conversations in preschool.A qualitative method has been used in the shape of interviews with educators, special educators and preschool principals working within different districts of a medium sized city in the south of Sweden.These interviews revealed that the use of guidance conversations is often controlled by specific needs and is used when a problem arises amongst the children. There are many expectations on the special educators role in these conversations, one of which is the role of conversation leader with the purpose of guiding the conversation amongst involved parties and give them the tools they need to resolve problems by themselves instead of delivering packaged solutions..

Acrylamide (AM) is a commonly used monomer in the manufacture of polyacrylamide. In addition, AM has been found in heated foods that are rich in starch. The main dietary sources in Sweden tend to be crisps, French fries, fried potatoes, crisp bread, cookies and coffee. Un-fortunately, dietary intake of AM has in several studies been shown to cause cancer in ro-dents. Consequently, the compound is currently regarded as a potential carcinogen in hu-mans.

Through analysis of the work of scheduling the doctors at the hospitals of Sundsvall,Gävle and Karolinska in Stockholm this thesis presents some conclusion about howand why a computer system would benefit these very tasks. The reason for doing thisis mainly to save money through more efficient scheduling, but also to minimizeerrors and maximize comfort for scheduler and doctor alike.Scheduling consists of collecting doctors? requests, assessing the need of staff,distribute the available doctors and make sure all tasks are covered throughout thescheduled period of time. The work is often very complex and involves manyvariables ranging from competence to personal whishes and economical constraints.Solving these problems takes a lot of time and energy which could be better spentcuring patients.The conclusion of this thesis is that there is reason to develop such a system to savetime and optimize resources. A description of the system is found in numerous lists ofroles, tasks and prototype sketches which combined shape the content andfunctionality.
