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.

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

If you move from Sweden to Portugal to work as an Art Director at an Ad agency, there are certain things you ought to know. Perhaps even before you decide to move. There are a lot of things that are quite different if you compare Portugal to Sweden, not only the language, but also the design, software, working hours and much more. You have for example two month with double salary, you work till six p.m. and when it comes to maternity leave, you have 100% compensation with no taxes the first four months of every pregnancy.

Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Seabased Industry AB develops system for extracting electrical energy from ocean waves with a Wave Energy Converter (WEC). The components is bought from subcontractors and then assembled into wave energy converters, buoys and marine substations by Seabased. In the future Seabased will produce more of the components themselves to reduce costs and to have better control over tolerances. The production line will also include the painting of the WECs and substations, which is performed in a painting line.The purpose of this thesis work is to study what is required to build a painting line, regarding the types of stations, transporting types and the space needed. This will result in layouts for the painting line.To receive the necessary information about production theory and corrosion and surface treatment, literature concerning this area has been studied.

I detta examensarbete har en tillförlitlighetsmetod tagits fram som väger samman kostnadspåverkande faktorer för investeringar och underhåll i eldistributionssystem med kostnader förknippade med avbrott. Syftet med metoden är att möjliggöra för nätplanerare och projektörer att jämföra olika investeringsalternativ för att kunna kostnadseffektivisera investeringarna i eldistributionssystem. Med tillförlitlighetsanalys kan den förväntade avbrottstiden i systemets uttagspunkter beräknas. Kopplas en kostnad till den förväntade avbrottstiden i uttagspunkterna kan den förväntade avbrottskostnaden för distributionssystemet beräknas. Syftet med simuleringarna har varit att undersöka om det går att minimera den totala kostnaden, investeringskostnader samt förväntade avbrottskostnad, genom slumpvisa investeringar i systemets ledningssektioner. Simuleringarna har genomförts på ett fiktivt mindre system.

In order to maintain a high safety level at a nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.

Det här examensarbetet har utförts på uppdrag åt Trollhättan Energi AB (TEAB). Examensarbetet är en utredning beträffande förutsättningar för sammankoppling av TEAB:s och Hjärtum Elförenings elnät.De nuvarande ledningsnäten har radialnät och det innebär att det endast har inmatning från ena ledningsänden. En sammankoppling skulle ge möjlighet till sektionerad drift vilket innebär inmatningsmöjligheter från båda ledningsändar. Det gör att ledningsnätet blir mer säkert, tillförlitligt och effektivt.Ett förslag på ett nytt ledningsnät där delar av TEAB:s och Hjärtum Elförenings ledningsnät är sammankopplade har tagits fram. Med det nya förslaget blir ledningsnätet mer driftsäkert och uppfyller lag- och myndighetskrav.Beräkningarna som ligger till grund för arbetet är teoretiskt utförda.
