In this master thesis a robot arm belonging to an automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain scheduling is a type of controller where the parameters of the controller are changed during operation, for example depending on the working point. First a nonlinear mathematical model of the system was made.

Blodtrycksförändringar hos skiftarbetare?Enligt den forskning som bedrivits under många år är skiftarbete förenat med en rad effekter på hälsan, däribland hjärt-kärlsjukdomar. Risken med skiftarbete är den förändring av dygnsrytm, och därigenom den biologiska klockan, som sker. Människans dygnsrytm har följts med ett stort antal variabler, bland annat blodtryck.Projektet syftade till att se om blodtrycksbilden skiljer sig mellan skift och dagarbete. De blodtrycksförändringar som mättes var medelblodtryck och blodtryckssänkning under sömn.

Denna intervjustudie syftar till att belysa behandlares erfarenheter av och uppfattningar om särskilda faktorer som påverkar behandlingsutfall hos ungdomar inom tvångsvården. Syftet innebär även att få kunskap kring hur behandlare resonerar om hur de förhåller sig till olika faktorer i behandlingsarbetet. Studien bygger på en hermeneutisk ståndpunkt och en kvalitativ ansats. Semistrukturerade intervjuer har gjorts med sex behandlare som arbetar inom ungdomsvården. Resultatet har tolkats utifrån teorin om risk- och skyddsfaktorer, behovsprincipen och responsivitetsprincipen.

The progress of chronic disorders such as heart failure and chronic obstructive pulmonary disease affects various aspects of life. They have an deep impact on patients´experience of health and wellbeing and their functional qualities and quality of life. Several studies have in an extensive way described heart failure and chronic obstructive pulmonary disease in its own domain but few qualitative studies consider coexistence of the disorders from a caring science perspective. The aim was to describe the meaning of living with heart failure and chronic obstructive pulmonary disease from a lifeworld perspective. With a phenomenological and reflecting lifeworld approach it´s possible to describe eight patients daily experiences of living with severe and chronic disorders from their own narratives.

This report discusses the IT archetypes "governance strategy" and how it could be linked to the IT benefits at the company. The study is based on IT investments that have taken place in ten banks operating in Sweden today, where the reality was modeled on the basis of a questionnaire survey and an additional interview. The aim was to examine whether it is possible to find any correlation between the governance in the banks and obtained benefits for an IT investments.While the competition is intensifying in most companies there is a greater demand for efficiency in IT. The need for IT solutions is greater than ever and the number of IT investments is increasing significantly in most workplaces today, especially on banks. But even if the investments are increasing in numbers it does not necessarily mean that all types of investments are effective and beneficial to the company.

The purpose of this essay was to examine whether there were any differences in social workers way of investigating boys and girls, age 13-15. The main questions we wanted to answer were; which were the factors that the social workers focused on? Did the investigations lead to a measure and if so, which one? How were risk and protection factors described and ana-lysed?To answer our questions we read and analyzed 22 reports, written by social workers 2004 at the department for teenagers and families at a social welfare service in Sweden. We came to the conclusion that there were some differences, but these were few and not extensive. Recreational activities was mentioned in a higher degree in the boys reports while health, housing conditions and network were mentioned more often in the girl´s reports.

AbstractDuring the last decade the public sector has been influenced by new ways of measuring performance and governing, taking inspiration from the private sector. The Swedish municipal community Vellinge has since 2004 adopted ?The Balanced Scorecard? by Kaplan & Norton, measuring not only the financial parts but also other, important factors. The adoption took place since the Swedish government applied new demands on county councils and municipal communities through ?God ekonomisk hushållning?.

Arbetsförmedlingen is the Swedish national authority responsible for the work politics, and its main purpose is to create and build a solid and sustainable job market.Economic crises together with changes in the society and in the organization over the past few years mean that the unemployed individuals that come in contact with Arbetsförmedlingen are no longer a homogenous group. A lot of effort is put into helping those who may find it difficult to enter the work environment, such as youths (19 ? 26 years old), people who have been unemployed or on sick leave for a long period of time, people with disabilities or immigrants who are newly arrived in Sweden.A harder social and economic climate can lead to frustration among the unemployed which mean that security measures at the offices has had to become adjusted. Local offices now have a public area where they have meetings with their clients and a locked open plan office space to which the public have no access. Working within an open plan office environment can cause health problems, mostly due to the constant background noise that comes from people having conversations on the phone, or with each other.

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

The aim of the study was to explore the psychological well-being of a group of adolescents in relation to how they regarded achieving in school, in a gender perspective. Twenty semi-structured interviews were conducted with students aged 17-19 at a high-achieving school in a big city in Sweden. The interviews were analyzed thematically and the results showed that the adolescents acted differently as well as regarded achieving in school differently depending on gender. The young women were driven by ambition, they were high-achieving and planning for the future. The young men cared less about achieving and thought more about the present.

Att vara förälder till ett barn med kolik kan innebära stora påfrestningar och risk för ohälsa för hela familjen. Syftet med denna litteraturstudie var att beskriva föräldrars upplevelser av att ha ett barn med kolik. I litteraturstudien analyserades åtta kvalitativa studier med kvalitativ innehållsanalys med manifest ansats. Detta resulterade i fyra kategorier; att den första tiden med barnet inte blev som förväntat, att känna rädsla inför att förlora kontrollen och skada sitt barn, att försöka klara av att vara förälder, att behöva stöd och avlastning under barnets kolikperiod. Det otröstbara barnet gör att föräldrarna upplever sig otillräckliga i sin föräldraroll, transitionen till föräldrablivandet försvåras liksom anknytningen till barnet.

Det råder en ökad tendens för den svenska småspararen att diversifiera sin aktieportfölj efter eget behag så att andelen obligationer och aktier tillsammans med utländska värdepapper och derivat kan ge maximal avkastning i förhållande till risk. Ett förekommande problem är dock att hitta rättvisa mått, matematiska och ekonomiska, som visar den korrekta bilden av en tillgångs utveckling i förhållande till marknadsportföljen varpå det krävs en förståelse för hur en tillgång eller en portfölj rör sig rent matematiskt. Utvalda aktier och obligationer ska avläsas ur måtten kovarians, korrelation, effektivitet och volatilitet och sedan ska resultatet ställas mot att enbart ha analyserat betavärdet för portföljen för att komma fram till lämpliga matematiska uttryck när man analyserar den diversifierade aktie/obligationsportföljen för en person med begränsad finansiell kunskap. Risken med urholkad valuta i utländska aktietransaktioner samt två olika optionsstrategier kommer också att redovisas rent grafiskt i studien för att visa utökade avkastningsmöjligheter..

The aim of this study is to describe what teachers and principals experience in schools regarding threats, violence and harassment towards teachers. A phenomenographical inspired approach has been used to describe and analyse the conceptions of five teachers and five principals. The findings of the study indicate that there is no impending risk for teachers to suffer from violence, threats or harassment. However, it does occasionally happen, and the findings of the study indicate that there are some factors that increase the risk. The major three factors are: fear, personality and inexperience.

Erasteel Kloster AB Söderfors have been commissioned by the county administrative board in Uppsala län to make an inventory of possible contaminations in theirs industrial- and landfill areas on the basis of the Swedish Environmental Protection Agency?s; ?Method of Surveying Contaminated Sites-phase 1? (MIFO-fas 1). The inventory starts with maps and archive studies, place visits and interviews, and finally a risk classification is done. A risk classification is a compilation of four categories; pollutant toxicity, contamination level, possible spreading condition of the pollutant, sensitivity and protection value of the environment. In this paper five partial areas (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin, Östra verken and Myrområdet) have been described from a historical point of view. Only parts of four areas have been risk classified (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin and Östra verken), due to that the other areas isn?t own by Erasteel Kloster AB. Holmen- and Jörsöområdet Holmen- and Jörsöområdet have during the entire activity time been carried out as the production core in the company.

Depression in young adults is a serious condition causing serious suffering for the victim. By finding risk factors for depression the opportunity for early preventive action is increased, which, in turn, may prevent a negative course. Two risk factors which have been shown to be related to depression are shame and rejection. Therefore this study examined the relationship between shameproneness, rejection sensitivity, shame-related events and depressive symptoms. The self-report questionnaires used were TOSCA, RSQ, Shaming index and BDI-II.
