Design av PID-regulator baserad på kommersiell processormodul

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.

(Om)skärningspunkten i en rättighetskonflikt: En kvalitativ textanalys av debatten kring manlig omskärelse

The purpose of this thesis is to build on the current debate on male circumcision and from thetwo perspectives, consequentialism and non-consequentialism, describe the conflict of rightsthat exists on the issue and outline a normative conclusion about whether Sweden should banmale circumcision of boys or not. The idea is to clarify how the two sides' approach to theconflicting rights differ on the issue. The perspectives intends to provide further clarity to thearguments and provide a framework to resolve the rights conflict by, which creates morefavorable conditions to understand the moral bearing of the arguments in the debate. Thesurvey is conducted as a debate analytical study, conducted by compiling and organizing thearguments for the various positions in the debate. Based on the two theories I conduct ancritical analysis in which I examine the extent to which the arguments of each side lives up tothe perspectives moral standards.

ADHD och fetma hos vuxna personer : En litteraturstudie

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

The role of cell cycle control mechanisms in regulated and sustained cell proliferation

The cell cycle is the time a cell spends between two cell divisions. The cell cycle includes several parallel processes, all of which must be completed before a cell is mature for dividing. In the first place, all subcomponents (RNA, protein and membrane lipids) need to double in quantity and this occurs continuously through the cell cycle. Furthermore, the genome and some chromosomal proteins must double and this take place during a limited interval in the middle of the cell cycle (S-phase). On either side of the S-phase are two "gaps" which is called G1 and G2. When the cell has passed a point in the G-phase they are irreversibly programmed to progress through the remaining of the cell cycle and will undergo the next cell division. When a cell have passed a point in the G1 phase, approximately four hours after mitosis, a normal cell is in a state of indecision.

?Varför går man inte hårdare fram?? En studie i krigsorienterad journalistik inom svensk public service.

Title:?Varför går man inte hårdare fram? ? En studie i krigsorienterad journalistik av Public Service från Ukrainakonflikten?Authors:Cemil Arikan, Staffan Florén Sandberg and Karl Henrik OlssonSubject:Undergraduate research paper in journalism studies, Dept. of journalism, media and communication (JMG) Gothenburg UniversityTerm:Spring 2014Supervisor:Mathias Färdigh, JMG, Gothenburg UniversityPages/words:48 pages/16701 wordsPurpose:The main purpose of the paper was to examine if and to what extent the conflict coverage of two Swedish public service news programmes from the ongoing Ukrainian conflict could be said to orientate towards either war or peace journalism.Method:Quantitative and qualitative content analysisProcedure:News broadcasts from Rapport 19:30 and Dagens Eko kvart-i-fem, covering the Ukrainian conflict, over a period of two months, were analyzed from the normative perspective of Johan Galtung?s peace journalism theory and Wilhelm Kempf?s theory of war and peace discourse.Results:Both Rapport and Dagens Eko were found orientating towards war journalism. Reports were given, in a great extent, to events of violence and verbal threats.

Entrébänk för Bonum seniorboenden

The following report comprises my bachelor´s thesis in Industrial design, 30 hp. It is executed in collaboration with Bonum senior housing, who has been the client and assignment- maker of this project.The goal was to design a bench for their entrances, which could represent not only the needs of the target group but also Bonum as a trademark. The work is done with great care for both human kind and the environment, with sustainability as beacon.The design process has been followed.Initially, you will find the definition of a bench for entrances, the framework including inclusive as well as sustainable design, a function- and market analysis followed by the inspiration part of the project. Getting to know the target group and their specific needs has been essential for this work.Investigations about what senior house living and senior products are and what the target group thinks and feels, has been done. As a result, two ?personas? has been developed.With the help of a purposely chosen group of people, surveys and ergonomic studies has been executed, as well as prototype-testing.The fact-finding has formed the stable and unavoidable foundation of this project, which later on gets more creative and idea based.

Undersökning av elkvalitet i distributionsnät med omfattande vindkraftselproduktion

The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.

Att folkomrösta eller icke folkomrösta? : En analys av debatten om huruvida EU: s grundlag bör antas genom en folkomröstning eller ej

The primary purpose of this thesis is to study how political agents construct and give meaning to the concepts of democracy, representative democracy and referendums. The starting point of the thesis is the pressing issue whether or not Sweden should hold a referendum on the new EU constitution. To analyze this question my choice of method is critical discourse analysis and the topical theories revolve around democracy and responsibility.My study shows that there are three different discourses in this debate: ?the democratic process?, ?the representative democracy? and ?the concept of democracy?. However, the meaning of the concepts in these discourses varies depending on which side the political agents are on.

Vakuumbrytare i småskaliga vattenkraftstationer

This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.

Although, spare-time interests and activities are what the men mainly focus on. Their interests are broad and all sorts of combinations occur why it is difficult to place the men in categories.

Kvinnors preventivmedelsanvändning under olika faser av det reproduktiva livet

Introduction: Studies have shown that women are not always satisfied with the effects of contraception and that contraceptive advice is perceived as non-specific. Aim: The purpose of this study was to investigate what contraceptive women have chosen to use in the different phases of their reproductive lives, and what they felt had influenced their choice. Method: A retrospective cross-sectional comparative study with a quantitative approach. A survey with fixed and multiple-choice options was sent to five hundred 45-year old women. Result: The study shows that various birth controls are different in the normal reproductive life.

Pelletring som marginalaffär för mindre sågverk/hyvlerier : en studie av 5 anläggningar i Småland

Denna studie handlar om pelletering som möjlig lönsam marginalaffär vid mindre sågverk/hyvlerier. Studien, vilken skett genom djupintervjuer på plats, omfattar fem olika mindre sågverk/hyvlerier i Småland. Verksamheterna är sinsemellan på många sätt olika men har samtliga satsat på pelletering av ekonomiska skäl och av miljöskäl.Studien visar att pelletering är lönsam men också att det krävs vissa förutsättningar för att långsiktigt nå denna lönsamhet. Den viktigaste är långsiktig tillgång till råvara i form av torrt spån men det krävs även ett genuint intresse och en stor kunskap inom såväl teknik som trä för den som skall pelletera Detta beror på att produktionsprocessen är mycket komplicerad och även beroende av en del yttre omständigheter som t.ex. fukt, kyla och torka.

Euthanasia: A Critical Analysis of the Physician's Role

Sometimes relatives have taken me on one side and told me they cannot bear it any more:"Isn't there something you can do to end it all?"More often requests for euthanasia have come from those who are ill. I remember visiting a man with lung cancer. He asked his wife to leave the room. As she closed the door he leaned over and grabbed my arm.

Slaget om Breitenfeld : En analys med hjälp av de grundläggande förmågorna, marktaktiska grundprinciperna och ledningsfilosofin uppdragstaktik

The Battle of Breitenfeld took place in 1631, during the 30-year war. It was the biggest battle the Swedish army has participated in. The essay analyses the battle from a Swedish-Saxon perspective, using the basic skills, ground tactical principles and management philosophy of decentralized command.The essay is based on a case study stemming from a qualitative text analysis, and is as such divided into three parts. The first part of the essay describes my theory, and explains what the different terms stand for. The second part narrates the battle and the participating armies.
