Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.

At ABB LV Motors in Västerås the shaft is assembled into the rotor with a shrink fit. After athorough investigation of the assembly method, several factors that make the insertion of theshaft more difficult has been discovered. Some affect the assembly directly while others onlyhave an indirect influence. The investigation has shown that the radial play between the shaftsouter radius and the rotors inner radius might be too small which could lead to anunsuccessful assembly. For the larger rotors, the condition is the opposite, and the rotor mightmove compared to the shaft direct after the assembly when the rotor still is warm.

This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.

The market for biofuels from the forests have had a positive development and the job initiators for this master´s thesis wanted to examine the profitability of a method for harvesting forest fuel, which was unfamiliar to them. The method was the ?long tree tops-method?, here called the LT-method. The LT-method is characterised by the fact that timber is harvested as the only roundwood assortment while the rest of the stem, which in other cases would become pulpwood, is harvested as forest fuel together with the logging residues. The method is based on the assumption that advantages in handling of the forest fuel assortment such as increased load weights for forest hauling and truck transportation, should compensate for the lower price for pulpwood when sold as forest fuel. The aim of the study was to compare the profitability of the LT-method with the GROT-method (harvest of timber, pulpwood and logging residues) and conventional logging without any harvest of forest fuel, and aslo to try to identify factors affecting the profitability of the different methods.

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.

The task was to deliver a solution that could be implemented in today?s production of the FH truck. To make the project successful it was most important that the end result had a high maturity level. For that reason an analysis of ergonomic, laws and regulations, and possible materials where conducted. To show that this project is profitable and can be realized a ruff cost estimated of material and tools is added to the research.

Factors from an investor perspectiveBackground and problem: In this study, we focused on the real estate investor and the factors and issues that may arise and affect real estate investment decisions. It has been put in relation to the other parties in the process of assessing and affecting real estate investment decision. The parties that we studied are real estate investors, banks, brokers and appraisers.Purpose: This study aims to describe and explain the factors that affect commercial real estate investments for investors, credit assessment conducted by the bank and valuation made by the broker and appraiser.Delimitations: We have chosen to limit the study to commercial real estates including residential, retail and office properties, industrial properties and combinations thereof. Agriculture buildings and forestry plots are not examined.

The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing. I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.

Under senare tid har det på den svenska livsmedelsmarknaden växt olika miljö- och kvalitetsmärkningar som grundar sig på olika kriterier. Vi har i denna uppsats valt att studera två av dessa: Svenskt Sigill coh SVENSKODLAT. Syftet med denna uppsats är därför att ur ett producentperspektiv, undersöka huruvida Svenskt Sigill och SVENSKODLAT certifieringarna kan utgöra en strategisk konkurrensfördel. Vi har identifierat tre aspekter som var och en i varierande grad kan sägas bidra till att de båda certifieringar vi studerat skapar konkurrensfördelar. Dessa tre aspekter vilka vi sammanfattat i en ABC-modell är: adding value, barrier to entry och cost saving.

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

Andelen flerspråkiga barn i Sverige ökar och följdaktligen så även behovet av kunskap om deras språkutveckling. Flerspråkiga barns språkutveckling har visat sig skilja sig i viss mån från den hos enspråkiga barn och då normer för flerspråkiga barns språkutveckling saknas i logopedisk verksamhet idag finns en osäkerhet kring hur deras språkutveckling bör bedömas. Föreliggande studie ingår i det internationella forskningsnätverket COST Action IS0804 och ämnar utgöra ett litet bidrag till en växande databank om flerspråkiga barns språkutveckling, i detta fall i jämförelse med enspråkiga barns språkutveckling. Studien utgår från 100 narrativer berättade av sex- och sjuåriga enspråkiga svensktalande och flerspråkiga engelsk-svensktalande barn. Narrativerna eliciterades med hjälp av två bildsekvenser från bedömningsmaterialet MAIN och samlades in inom ramen för tre tidigare magisteruppsatser i logopedi från Uppsala universitet.

In Sweden, harvesting pre-commercial thinning (PCT) stems for energy purposes is a interesting way of financing the high cost of preparing dense stands for a profitable first conventional thinning. This concept can be labelled bioenergy thinning. The aim of this study was to quantify the productivity of a Vimek 404R light harvester with an accumulating Naarva-Grip cutting head during the bioenergy thinning of a self-regenerated stand west of Sunnansjö in Dalarna. The stand was birch-dominated, contained 15 371 stems/ha, and measured on average 4,6 cm Dbh and 7 m tall. Even though the driver was well experienced with the machine, the stand in question was the first one that he ever thinned in this manner. Nevertheless, the driver strived to accumulate as many stems as possible during each crane cycle and chose to cut taller stems in half so as to make the handling and forwarding of the harvested stems easier.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

Arbetet visar praktiskt hur en organisation kan utnyttja kvalitetsbristkostnader, för att sedan utifrån dessa identifiera möjligheter till förbättring. I arbetet används identifierade kvalitetsbristkostnader för att ta fram en projektplan för motortillverkningen. Projektets resultat ska medföra att kvalitetsbristkostnaderna vid motortillverkningen minskas. Arbetet börjar med att identifiera vilka kvalitetsbristkostnader som motortillverkningen har dokumenterat. Därefter tas en enkät med öppna frågor fram, vilken behandlar kvalitetsbrister vid motortillverkningen.
