The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Abstract.The levels of dioxin and comparable substances rose to a large extent in our environment during the second half of the 20'Th century. This was the result of the synthesis of, and careless usage of these substances in cooling fluids, hydraulics, pesticides etc. Background levels of dioxins and furans in sealed samples prior to this era suggest that former sources of these substances existed. Salt glazing is a method of adding a smooth acid resistant exterior to stoneware ceramics. The technique has been in use since the 16'Th century, maybe even earlier than that.

For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

Syftet med detta arbete var att på ett tydligt sätt beskriva respondenternas upplevelse av anställningsotrygghet för ca 7 år sedan. Hur detta har påverkat deras hantering och upplevelse av liknande händelser i efterhand. Förteorierna som vi använde i vår bakgrund var bland annat det faktum att många människors anställningar har blivit osäkra och föränderliga. Ansatsen var kvalitativ med en hermeneutisk tolkningsspiral som transkriberingsmetod. Det psykologiska kontraktet, hantering och upplevelser av stress togs vidare upp i vår fördjupning och konkretisering som till exempel miljöstress, betingning och känslan av sammanhang. Resultatet av vårt arbete är att deltagarna efter ca 7 år fortfarande upplever en sänkt förmåga att hantera stress, respondenterna beskriver en kvardröjande osäkerhet, sänkt tilltro till sin egen förmåga och en ökad känslighet för stress. Ett av de resultat vi fann var att otrygghetens följder gav nyckelord som kunde kategoriseras under utbrändhet. I diskussionen hanteras deltagarnas beskrivning av kvardröjande osäkerhet, sänkt tilltro till sin egen förmåga och misstänksamhet.

Undersökningen omfattar företag som har tagit emot elever både under den traditionella och under den nya praon. praon är skolans samverkan me dnäringslivet och syftet är att ge en blid över hur företagen i kommunen ser på den nya praon och dess förändring. Det finns en allmän verdertagen uppfattning om att lärare och elever har mottagit den nya praon med visst missnöje. En enkät har utformats och sänts till 65 företag, kommun och landsting. Av de 65 företag, kommun och landsting svarade 37 stycken.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

This is a paper about the social services waiting rooms. Our aim with the study has been to:?Describe and problematize the physical environment in social services waiting rooms. A wider purpose is to lift the question about the waiting room as a significant part of peoples encounter with the social services.? To be able to achieve this purpose, we have used two questions: What does the physical waiting room environment look like in social services in Stockholms län? How can we understand and problematize the physical environment factors impact on people who visits these environments? We have observed and photographed ten waiting rooms in ten different social services in Stockholms län.

For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire. Subsequently, a number of different methods were used to develop a final solution and make aprototype.The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer.

This study examined if individuals act in a less discriminating way and in a more fair way when they receive instructions about justice and not being discriminating while recruiting. 96 randomly assigned students at the University of Lund participated in this study. The participants were informed that they would act as a recruiter. They would then choose and place three of the best personal record in order of preference. There were three different kinds of company policies/instructions.

Uppsatsen har syftet att besvara huvudfrågan: Hur betraktar nutida psykoanalytiker och psykodynamiskt inriktade psykoterapeuter förhållandet mellan värderingar och psykoterapi / psykoanalys och hur ser de på sin behandlarroll utifrån detta?För att ta reda på hur nutida teoretiker besvarar denna fråga gjordes en begränsad litteraturstudie. Med hjälp av ett frågeformulär undersöktes också hur ett femtiotal svenska praktiker - psykoanalytiker och psykodynamiskt inriktade psykoterapeuter - förhåller sig till frågan om värderingar och inflytande i psykoterapi.Resultatet av litteraturgenomgången visar att en problematisering av det psykoanalytiska neutralitetsidealets objektivistiska utgångspunkt ägt rum bland teoretiker inom fältet och att dessa på olika sätt försöker hantera inkongruensen mellan den traditionella behandlingssynen och nutida kunskapsteori. Psykoanalytikerns kunskapsanspråk i behandlingen problematiseras och den psykoterapeutiska relationen - som nu betraktas som behandlingens kurativa inslag - tenderar att uppfattas konstruktivistiskt. Hos flera av de teoretiker som ingått i litteraturstudien kan man också skönja en tendens mot att omformulera behandlarens roll i mer pedagogiska termer.

The purpose of this study is to examine how the identity of teenagers is affected by the loss of a parent as well as what coping strategies support identity development. The reactions the teenagers exhibit, in such circumstances, will also be examined. To accomplish this,  a theory package was created, comprising theories in developmental psychology, identity work, coping and theory of grief reactions of children and teenagers. This package provided a broad perspective, which facilitated the analysis. Furthermore, it made it easier to address the purpose and the issue of the analysis.

Syftet med den här uppsatsen var att få en förbättrad förståelse av hur unga chefer upplever sitt arbete inom offentlig sektor och hur det psykiska välbefinnandet påverkas av arbetsbelastningen. Undersökningen har gjorts utifrån semistrukturerade intervjuer med fyra enhetschefer om deras upplevelser av arbetskrav samt psykiska välbefinnande där analysprocessen samt grunden för studien följer den fenomenologiska ansatsen. Resultatet visar utifrån chefernas upplevelser att det finns starka samband att det psykiska välbefinnandet påverkas negativt av för hög arbetsbelastning. De tydliga faktorer som skapar ohälsan är arbetsansvaret, arbetstiderna och också de höga ambitioner som chefer kan ha. Studien konstaterar hur yngre chefer har större tendens till stressrelaterade sjukdomar till följd av arbetspressen som unga chefer anses ha.
