?Optimizing the workflow of hydraulic reservoir tanks? is a degree project made by Jonas Olsson, student within the faculty of technology and science, during spring semester 2012. The project comprise 22,5 ECTS.Volvo Construction Equipment, located in Arvika, was the client in this project. The mentor at Volvo CE was A?sa Barck, and the mentor at Karlstad University was Monica Jakobsson.

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

Uppsatsen behandlar olika definitioner av korruption utifrån internationella regelverk. The United Nations Convention against Corruption (UNCAC) ger en mer specifik definition till korruption än the African Convention on Combating and Preventing Corruption and Related Offences (AUCPCC). Då det finns flera olika definitioner av korruption kan diskuteras huruvida en enhetlig definition är nödvändig. Korruption påverkar även rätten till att bli prövad av en självständig och oberoende domstol. De internationella regelverk som behandlar denna rättighet är the Universal Declaration on Human Rights (UDHR), the African Charter on Human and Peoples? Rights (ACHPR) och the International Covenant on Civil and Political Rights (ICCPR).

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

I valupptakten hösten 2010 fick Sverigedemokraternas två valfilmer oerhört genomslag i media, och hade inte mindre än en halv miljon visningar på Youtube, på bara några få dagar. Denna här uppsatsen undersöker vilka strategier som ligger bakom ett sådant genomslag i media. Frågeställningen försöker besvara vilka verklighetsbeskrivningar som TV4 respektive Sverigedemokraterna (SD) ger i sitt pressmaterial angående lanseringen av SD:s två valfilmer, och vad de får för effekter.Uppsatsen analyserar nyckelord som används, vilken ram de sätter på situationen och om SD använder sig av anti-etablissemangsstrategin. Den diskuterar också omkring problemformuleringsprivilegiet, det vill säga att den som formulerar frågeställningen alltid äger tolkningsföreträdet till den.Uppsatsens slutsats är att SD:s strategi vid lanseringen av valfilmen var att synliggöra och förstärka avståndet mellan SD och etablissemanget, såväl till politiska partier som till media. SD använde sig av de egna problemformuleringarna massinvandring och censur, som i sin tur skapade egna ramar, till vilka enbart SD hade tolkningsföreträde.

This study departs from Gállok, an area 40 kilometres northwest of the city Jokkmokk, in northern Sweden. This is a place to which local people and Saami reindeer herders have material interests and emotional bonds. The mining company JIMAB wants to prospect for extracting minerals from this area. In the summer of 2013 local people, Saamis and environmental activists gathered in Gállok in order to protest and make resistance against these plans. Activism was made, debate articles were written, demonstrations were organized and information about what was going on in Gállok was shared through social media.The aim of this study is to examine the cultural processes of the anti-mining movement, in particular the happenings in Gállok in summer 2013.

The aim of this paper is to examine how teachers experience their possibilities to develop democratic teaching in high school and how they reflect upon their position of power within the teaching situation. Four professional high school teachers have been interviewed for the study. The theoretical perspective of the study is an intersectional view on power and a view on democratic teaching which is partly built on the high school curriculum, but mainly defined by deliberative conversations, anti-oppressive education and norm-critical education. The result of the study is focused on three themes, which were shown in the analysis of the interviews. These themes are: choices of teaching content,  authority of the teacher and democratic teaching.

Historical research about the so-called New Left was until the late 1990s an entirely newacademic field in Swedish academia. However, a large part of this research still deals withquestions concerning ?who did what? and perhaps more notably ?who was right?.This thesis is an attempt to move away from such inquiries and instead look towardshow one albeit small but very important part of this so-called New Left discussed andused the term America and things American. Formed largely around the Anti-WarMovement, the Marxist-Leninist ? or ?Maoist? ? Left naturally opposed US worldpolicies; but perhaps more interesting a significant part of the ideas about America andthe Vietnam War seemed to stem from USA itself ? such as naming your anti-war folkgroup ?Freedom Singers? after the US civil rights group ?The Freedom Singers?.Analyzing three Swedish Marxist-Leninist magazines the study thus complements theresearch on not only the Swedish New Left but also the study of anti-Americanisms;firstly, by examining what the Marxist-Leninist left considered particularly American;secondly, by studying in what context these particular Americanism was discussed; and,thirdly, by observing if these notions changed over time, and why.

Denna uppsats studerar kultserien Buffy the Vampire Slayer (1997?2003) utifrån ett schizoanalytiskt perspektiv genom att applicera tre huvudsakliga begrepp inom Gilles Deleuzes och Félix Guattaris teorier på sju avsnitt, en från varje säsong; dessa begrepp är Anti-Oidipus, begärsmaskinen och krigsmaskinen. Syftet med uppsatsen är att undersöka huruvida vännerna i serien först och främst är en anti-oidipal familj. Den utgår från tre analysfrågor: Är de som en grupp en begärsmaskin? Är gruppen ?schizofren?? Utgör de tillsammans en krigsmaskin? Studien visar på karaktärernas samspel och sammanhållning som en grupp på ett sätt som visar att begreppet familj inte endast kan definieras av blodsrelationer utan av sammankopplingar vilka snarast är att beskriva som maskiner.

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

De senaste årens långa och kalla vintrar har lett till ett ökat antal halkolyckor. Genom att undersöka halkolyckors utsträckning samt halkskydd som fanns tillgängliga konstaterades det att ett behov av nya halkskydd fanns. Enkäter för att ge svar på användning av halkskydd togs fram och svar från personer i åldrarna 20-65 visade att man överlag inte använde halkskydd. I stor utsträckning berodde det på halkskyddens dåliga kvalité och den negativa stämpeln som fanns på dem . Textila material undersöktes för att finna lämpliga egenskaper.
