Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

My work has been to create a magazine for iPad to explore this format, whichthere are mixed feelings about. Instead of seeing the digital format as an enemy ofthe printed magazine, I have chosen to see it as an opportunity.I have given myself the task of designing a magazine that can justify the useof the digital magazine. I have looked at the identity of the magazine, but mainlyexplored the format and its prerequisites.I was triggered to do the project when I saw people who are just making a pdfof the printed magazine and publish it digitally. I have during my work discoveredhow near or far away you can be from the printed magazine.The format of the iPad has multiple aspects to look upon; one that turned outto be clear in my project was navigation. Working with a spread has its problemsand opportunities; the same applies to an article that is larger than a screen.

Young adults with mild intellectual disability and their thoughts about the own home was investigated and is described in this thesis. A qualitative research method was used, and the respondents thoughts about where and how to live were gathered through interviews. The investigation is based on the theoretical concept of normality, identity and quality of life since these aspects are important components of the individual's positive experiences of their homelife. People with disabilities has rights goverened by law, but in this thesis the individuals subjective experiences, feelings and wishes are described. The importance of the individual2019s rights to make their own decisions, feeling of pericipation and personal security was found to be important factors for a satisfying living environment.

In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. The model to describe GDP has been calculated using multiple line arregression. In order to reach a reliable final model the number of covariates has been gradually decreased to eliminate insignificant covariates.

This essay is about personal assistance for persons with considerable intellectual disabilities.The purpose with the study is: to examine personal assistance for individuals, who can`t speakfor themselves, to examine how the individuals can determine and get influence into theirassistance and how they can get help with it, to examine the role of an representative inrelation to the serviceuser´s assistance and examine if there are factors of gender in theinterviews.The chosen method is qualitative interviews.The interviews has been analysed through earlier research about personal assistance andtheoretical perspectives like: influence, integration and citizenship and discussed throughperspectives of social psychology.The main conclusions are: the influence the serviceusers can have is through persons whoknow them very well, the role of the representatives are indistinct, the serviceusers can´tdetermine their assistance themselves and need help with it from relatives, representatives,personal assistants and managers, the persons who know the serviceuser intimately are best totransform the needs to assistance. The factors of gender, are that there are more men aspersonal assistants than in the care of elderly, and the representatives are mostly men. Thepersonal assistants appreciates the time they have for the serviceuser, the work can be lonelyand demanding..

As a soccer coach for youths with disabilities and as active soccer players, our thoughts regarding the basic principles of sports where awakened and how it corresponds with the possibilities of disabled youths participating in club organized sports. From that thought came the idea that, with our team as the point of original we should contribute with increased knowledge regarding the experiences of disabled youths doing sports. Using ethnography and co-operative observations we have researched both including and excluding factors that contribute to the possibilities of disabled youths opportunity to do sports. We have been able to distinguish that the youths in question feel that sports can be identity-building as well as give a sense of community. The study shows that the basic principles of sports does not correspond with reality because the lack of availability is the determinant factor. .

Background: Mental illness is a growing public health problem which can cause significant disabilities and lead to poor quality of life. As primary care nurses often are the first to encounter these patients they need knowledge to be able to respond appropriately to this group.Aim: The aim was to describe how the sufferer of mental illness experiences the introduction to primary care. Method: The literature review was based on the results of 11 scientific articles which were analyzed with the inspiration of a metasynthesis method.Results: Four categories emerged: the experience of being treated like a human being, the importance of a therapeutic space, the experience of time and availability as well as the importance of competent personnel and the importance of continuity. Patients described different aspects deemed important when encountering nursing staff.

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

This essay will discuss consumption as a strategy for creating one?s identity for persons with visible disabilities. Along with this, questions asked and answered are concerning how lack of inclusion in the fashion industry affects the informants? consumption of clothes and how the informants discuss identity in relation to their disability. Compulsory able-bodiness (McRuer, 2006) is a main theory that will influence both the discussion and the results.

Syftet med denna studie var att beräkna preliminär prevalens för sjukdomen multipel skleros (MS) i Värmland, med prevalensdag 21 december 2002, och jämföra den med andra prevalensstudier i Sverige. Utifrån patientjournaler vid länets sjukvårdsinrättningar noterades basala och medicinska data på ett registreringsformulär. För klassificering av MS har Poser ?s kriterielista tillämpats och granskningen av journaler har utförts av specialist neurologer. Prevalensen för definite/probable MS i Värmland, baserad på siffror som var insamlade augusti 2004, var 151/105 (95% CI 136-165), för kvinnor var prevalensen 211/105 (95% CI 187-235) och för män 89/105 (95% CI 73-105), vilket innebär att MS var 2,37 gånger vanligare för kvinnor.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

The purpose with this thesis is to analyse different factors that can explain district heating prices for energy companies in Sweden. We are further interested in examining if the prices is affected by the use of industrial waste heat in their production and the company?s ownership structure. The method applied is a multiple regression analysis using a panel data set of 50 companies over 5 years (2008-2012). The data used is yearly data obtained from the Swedish district heating association.

Syftet med detta arbete är att designa och utvärdera ett stridssystem för ett rollspel, som skall ha en högre grad av meningsfulla val än de två kommersiella rollspel som utvärderas tillsammans med det egenutvecklade stridssystemet. För att få en högre grad av meningsfulla val så designas stridssystemet efter två teorier: triangulära val och multiple-dice systems. Graden av meningsfulla val utvärderas genom strukturerade intervjuer där respondenterna svara på en enkät.Utvärderingen visade att det egenutvecklade stridssystem inte uppnådde en högre grad av meningsfulla val än de två kommersiella stridssystemen.Rollspelet bör i framtiden modifieras för att korrigera de problem som framkom genom utvärderingen. Utvärderingsmetoden som användes i arbetet kan utvärdera graden av meningsfulla val i alla typer av spel..

The purpose of this study has been to increase the awareness of what significance models of explanation have for intervention programmes, aimed at perpetrators of intimate partner violence, within the Swedish social services. The study is not gender neutral, it centres on male batterers in heterosexual relationships. The study is based on qualitative interviews with five people working within the topical field. I analyzed their statements using an ecological model of understanding violence. The main finding was that the people I interviewed had a multiple understanding when it came to comprehending the violence, but that when it came down to the actual intervention they targeted mainly on elements in the individual spectra, such as feelings of frustration.
