When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

Background: Young adults undergo a phase in life when they try to become independent individuals and are expected to take responsibility. The transition to adult life, cause hardship for all young adults, but with concurrent mental illness this transition can be more complicated. The young adults may need support from their parents in connection with care.Aim: The aim of this study was to describe nurses' perceptions of parental participation in the care of young adults with mental illness.Method: To describe the perceptions of a phenomenon, qualitative interviews with a phenomenographic approach were conducted. The interview texts were analyzed into five description categories and 10 perceptions. In the study, eight nurses were interviewed.Results: The result shows that parental participation in the care is based on the young adult's decision.

I detta arbete fokuseras förhållandet mellan barn och kartor. Litteraturstudien behandlar vad en mental karta är, hur den formas och vilken funktion denna har.

The purpose of this study is to understand how street-level bureaucrats, working with clients with mental illness, are implementing their statutory obligation of support for family carers who are caring for or supporting relatives with mental illness. The study are based on vignettes and qualitative interviews with social workers in three different municipalities in southern Sweden. The questions of this study are:? How do the social workers communicate their statutory obligation of support to family carers?? How do the social workers distinguish the family carers?? How do the social workers distinguish the family carers who are in need of support? Metod: Vignettes and qualitative interviews has been used as methods to gather empirical data.Theory: Theories of street-level bureaucracy has been used as theory in the analyses of the empirical material.Results: The result of this study concludes that the social workers, in lack of policy introduction, communicate their obligation to support family carers within their discretion. The result shows that the majority of the municipalities do not have formalized support for family carers supporting relatives with mental illness. The study also concludes that the social workers have different understandings of which family carer who is a carer in need of support.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

Bakgrund: Övervikt och fetma (obesitas) är ett allvarligt globalt och nationellt folkhälsoproblem. Tidigare studier har visat att fetma är förknippat med nedsatt livskvalitet och mental ohälsa hos vuxna, tonåringar och barn. Dock har få studerat sambandet mellan fetma och livskvalitet bland unga vuxna. Syftet med denna studie var att beskriva hälsorelaterad livskvalitet, mental hälsa och antropometriska mått hos en grupp obesa unga vuxna i åldern 16-25 år (n=203) samt att göra en jämförelse mellan deras hälsorelaterade livskvalitet och resultat från populationsstudier.Metod: En beskrivning av den aktuella gruppen genomfördes med hjälp av de data som samlats in vid inskrivningstillfället vid överviktscentrum på Norrtulls sjukhus. Den hälsorelaterade livskvaliteten mättes med hjälp av Euroqol five dimensions (EQ5D) och resultatet jämfördes med befolkningsstudier utförda i Stockholm, Uppsala och Jämtland där samma instrument använts.

There are widespread discussions about the use of retouched models in media, ranging from bloggers to legal decision-makers. Research shows that there are negative psychological effects on especially females being exposed to idealized, retouched model images. The purpose of this paper is to explore the effects of using retouched models in advertising from a marketing perspective, based on attitudes, perceived quality and purchase intentions.Based on theories about attractiveness, halo-effects and social comparison, an experimental study was done, investigating the different responses on above mentioned parameters to advertisements showing either retouched model images or non-retouched model images. Initially it was also tested if the retouched models were seen as more attractive than the non-retouched models. The results showed almost no differences between the reactions to the advertisements with retouched models compared to the advertisements with non-retouched models, when all respondent groups were analyzed together.

Denna kvalitativa intervjustudie söker svar på frågan hur rehabiliteringsarbetet med kommunalanställda som är långtidssjukskrivna på grund av mental ohälsa i Burlövs Kommun fungerar. Detta arbete sker i samverkan mellan flera aktörer och studeras därför som ett projekt där de olika aktörerna utgör projektets deltagare. Det empiriska materialet analyseras med hjälp av de teoretiska analysverktygen Rationalitet, Verklighet och Makt.Studien visar på brister i rehabiliteringsarbetet som framförallt beror på en ojämnlik maktfördelning inom projektet. Arbetsgivarens syn på sjukskrivning, mental ohälsa och rehabilitering styr i hög grad projektets början, riktning och slut och flera av de övriga projektdeltagarna upplever därför att deras kunskap och möjligheter att bedriva en god rehabilitering ignoreras. Inte minst gäller detta de sjukskrivna själva som känner sig misstrodda, övergivna och pressade i rehabiliteringsarbetet, vilket förvärrar och försvårar deras aktiva väg tillbaka till arbete och långsiktig hälsa..

The flexibility of the labour market is considered as an instrument for increasing economic growth.Therefore has the use of flexible employment, also called atypical employment, increased. The atypical employment is characterized by insecurity in comparison with a traditional permanent full- time employment. One of the most common atypical employments is the manning employment, which is insecure whether it is permanent or not. The insecurity in the industry is based on insecure income, unpredictable working hours and poor psychosocial work environment.In order to encourage a continued increase of flexibility in the labour market while the need for security for staffing employees would be satisfied was Directive 2008:104 adopted. A certain amount of security has been achieved.

Användaracceptans är en viktig del i alla systemutvecklingsprojekt och är också en väldigt lättpåverkad variabel för en lyckad implementering. Därför är det viktigt att ha översikt på sådana faktorer som kan påverka användaracceptansen negativt, en sådan faktor är försening. Denna uppsats belyser sammanhanget mellan hur en försening påverkar användaracceptansen. Genom att låta en undersökningsgrupp genomgå en enkät utformad efter Technology Acceptance Model har jag samlat upp en generaliserad åsikt. Resultaten visar att försening som variabel inte påverkar användaracceptansen för fallstudien..

That many creative workers have uncertain and uneven incomes is well-established, but how or why they make a living is not. This paper examines the elusive value exchanges between creatives, buyers, consumers, and other economic supporters, and offers a model of how creatives make a living. By mapping income statistics of Swedish creatives together with in-depth interviews some patterns emerge. This, combined with Bourdieu's theories of social, cultural and symbolic capital, and Knorr's objects of sociality, forms a basis for a structured model of value exchange. The paper shows how creative workers create economic and non-economic capital (capitalization), how they advertise this capital (signaling), and how they convert between different types of capital (conversion) in order to make a living.
