The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.

This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of  the analyzed bones met the quality criteria. The isotop data showed that import of Atlantic cod was significant in medeval Sweden. The analysis suggests that there is no specific time or event that the sites start to import cod but this varies from site to site. .

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

The purpose of this study was to examine the foreign news flow in Sweden´s largest news agency TT. Since TT has an important position as a news provider to most of Sweden´s local and national news outlets, it was important to examine exactly what their news stories consisted of.The theoretical background of this study consist of theories of news values, agenda setting, dependency theory and the theory about the ?news shadow? a lack of coverage leads to.In our quantitative study we have looked at 506 articles taken from the TT news flow during two weeks In November 2013. We have studied which continents and countries the news origins from, who have supplied the text, the topics of the news, which one gets to speak in the text and what general tone the story has.The study shows that the supply of news follows the criteria of news values. It also shows that in some regions of the world the coverage is almost nonexistent.

The aim of this study is to examine the collection One Thousand and One Nights (also: The Arabian Nights) from a european perspective, by comparing different european translations. The study focuses on three translations into Swedish from different periods of time and how the tales have changed in the translation process - depending on the prevailing line of approach and Western perceptions of Eastern standards. The thesis of the study is that Eastern culture, from a Western perspective, has been seen as exotic and different but not as a high literary culture and that this view has affected the translations into european languages. The study shows, among other things, that Western culture is many times considered normative in the translations and that the translators often give their own voices a prominent role, also that common Western notions of the East affects the translations.The word ?orientalism? is used frequently in the study and it refers primarily to the image of the Orient as it is described in Edward Saids' book Orientalism: as a Western construction whose main purpose is to strengthen its own conception of the Orient and thereby strengthen the Western identity as better than the Orient.

The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable. The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Syftet med studien är att bidra till kunskap och förståelse kring fenomenet gamification. Denna kartläggning bidrar till att klargöra för- och nackdelar, möjligheter och risker samt eventuella fallgropar med gamification. Om en organisation är medveten om dessa aspekter kring fenomenet minskar riskerna för att någonting ska gå fel, vilket potentiellt skulle kunna bli kostsamt.Studien vilar på en teoretisk referensram hämtad från såväl managmenent- som psykologiforskningen. Förväntansteorin, self determination theory, flow, McGregors Teori X och Y, principal-agentteorin är några av de teorier som används för analysen av gamification.Då det handlar om en kartläggning kring ett relativt nytt fenomen behandlas flera exempel på gamification hämtade från företag som verkar inom branschen. En intervju med speldesignern Henrik Englund finns också med, samt en fallstudie kring polismyndighetens omskrivna användning av spelelement.
