Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv
The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.
Solenergi på Kvarnholmen
In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.
Kålhuvuden och kopparputs : Läsaren som husmoder i svenska familjetidningar
Domestic weekly magazines in Sweden are characterized by an emphasis on practical editorial material such as cooking recipes and knitting patterns, and also contain a comparatively large share of reader material. This makes it possible to study the readers through texts produced by themselves. The aim of this study of columns of readers' tips on domestic work is to analyze how readers embody a specific femininity centered around the woman as responsible for the home, in the sense of everyday maintenance as well as aesthetic development. The author defines this femininity as "home maker". The theoretical framework for the analysis is the sociological theory of Pierre Bourdieu, and Jonathan Potter's and Margaret Wetherell's model of interpretive repertoire is also used where modality is discussed.
Indentifiering och reglering av industrirobot med hjälp av accelerometer
Dagens robotindustri har som mål att bygga billigare och lättare robotar, vilket ger allt vekare robotar. Denna rapport studerar identifiering och reglering med en extra armsensor ? accelerometer ? på en flexibel industrirobot. Studien har skett både simulerat och experimentellt på en industrirobot.Vid identifiering med accelerometer befinner sig accelerometern i ett roterande koordinatsystem. Denna rapport presenterar en kompenseringsalgoritm för att transformera signalerna från det roterande koordinatsystemet till ett rumsfast koordinatsystem.I denna rapport presenteras regulatorstrukturerna I-PID, II^2-PID och LQG, vilka alla återkopplar motorvinkel och armvinkelacceleration.
Den svenska lönebildningen i förändring
Problem: The Swedish wage-setting has changed since the time for the breakthrough of the industrialism until today. Before that, wages often consisted of perquisites or goods that could be exchanged against other goods. Rural people were often self-sufficient. In some cases the farmer owned the land, in other cases they where tenants. At the time for the breakthrough of industrialism the demand for similar labour were increased.
Affärsupplägg biobränsle Västerbotten : en undersökning av större biobränsleanvändares syn på biobränslemarknaden i Västerbotten
The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.
Stress, coping och utbrändhet: en undersökning av anställda inom hemtjänsten
Undersökningen handlade om stress, coping och utbrändhet bland anställda inom den kommunala hemtjänsten. Syftet med undersökningen var dels att undersöka sambanden mellan upplevd stress och tre dimensioner av utbrändhet (emotionell utmattning, cynism och prestationsförmåga), dels att undersöka vilka copingstrategier som är associerade med dessa utbrändhetsdimensioner. Ytterliggare ett syfte var att undersöka om de anställda kunde karaktä-riseras som utbrända. Ett frågeformulär distribuerades till 100 anställda inom den kommunala hemtjänsten i Malmö svarsfrekvensen var 41 %. Stress mättes med Perceived Stress Scale (PSS), coping har mättes med Brief COPE och utbrändhet mättes med Maslachs Burnout Inventory (MBI).
Gnosjöandans barn och deras framtidsvisioner : En studie gjord på Entekprogrammet i Gnosjö
The aim of this thesis is to study and analyze a village in the southern of Sweden called Gnosjö, which is famous for a special spirit of industrial success and entrepreneurship. Gnosjö has been successful and famous for many years but is now standing in front of several threats, like a growing number of out moving inhabitants, a low standard of education and difficulties for women to make carrier. Trying to reduce the threat of young inhabitants moving out, a new education program started three years ago with the purpose to make young students to be more interested in the technical development of the industry and make them stay in the district and hopefully be entrepreneurs.The research questions are; which consequences does ?Entekprogrammet? and the background of the students have on the students view on the spirit of Gnosjö, carrier in the local industries and wish of staying or moving from Gnosjö. Furthermore, I want to see if there are any differences between the girls and the boys, does sex have an influence on the view at the future? The study is made by qualitative and quantitative method.

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.
Individualiseringens dilemma : Hur uppnås ett fungerande samspel mellan individualisering och gemensam undervisning i matematik?
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.
Skogspolitik i Sverige
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.

Prognostisering av aktieavkastningar med hjälp av makroekonomiska variabler - en svensk studie
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.
