An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Manual signs are an augmentative and alternative communication mode which enables and facilitates communication for persons with impairments in speech, language and hearing. There are different ways of teaching signs to persons with intellectual disabilities. One of them is milieu teaching, which is a method where the teaching takes place in natural settings. This method has proven to give good results in generalization and maintenance. Teaching signs to staff in groups has been shown to be effective.

Pontarius AB har tillsammans med Göteborgs Hamn AB identifierat behovet av en utvecklad holistisk modell för bedömning av investeringar i terminalytor. För detta har en första ansats gjorts med den interna livscykelkostnadsanalysmodellen Total Cost of Ownership and Operations (TCOO). Livscykelkostnadsanalys (LCCA) är ett verktyg för att handskas med ett projekts totala kostnader vid investeringsbeslut och bedömning av alternativ. Generella livscykelkostnads-modeller är svåra att ta fram, varför istället utförliga modeller vanligen skapas för specifika områden. För vägbeläggningar, och tillviss del flygplatsbeläggningar, finns utförliga sådana metoder, men för beläggningar i containerterminaler saknas det.För att fortsätta utveckling mot en bättre bedömningsmodell för terminalytor syftade studien till att identifiera kostnadsparametrar som sett ur ett livscykelperspektiv påverkar kostnaderna för containerhamnterminalytor.

Companies constantly strive for the perfect order which enables them to satisfy and retain their customers. This is a difficult process that can be facilitated by using different picking technologies. In this study, a research of the picking technologies Pick-to-Light and Pick-to-Voice have been made to investigate when each technology is suited.In order to collect relevant information and data to be able to answer the question formulation, a qualitative study with interviews have been made. The purpose of this essay was to investigate Pick-to-Light and Pick-to-Voice to see when each technology is best suited and to see what the differences between the technologies are. With our essay we wanted to help manufacturing companies to make the right decisions when implementing a picking technology.The results showed that those picking technologies give companies a higher picking quality and an increased work efficiency since the order picking is faster to perform, and that picking errors are reduced.

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

Studies show that visual elements in store have a great impact on consumers. Of all the impressions that the brain receives the visual impressions count for 83 %. One of the visual elements that retailers can use in-store to influence consumers is signs. Today, there are a lot of studies on regular signs but this is very limited when it comes to motion displays. Motion displays are signs printed on electronic paper with animated messages.

Den här uppsatsen är skriven på uppdrag av GrenseTjänsten Morukulien, vilken är en organisation som hjälper personer, företag och andra organisationer som har ärenden i både Sverige och Norge.Syftet med uppsatsen är att jämföra levnadskostnaderna för en tvåbarnsfamilj i Arvika- och Kongsvinger Kommun. Detta görs genom att se vilken familj som har störst köpkraft. Med köpkraft menas hur mycket man kan konsumera för sin disponibla inkomst.Levnadskostnaderna jämförs för en genomsnittlig tvåbarnsfamilj. Undersökningen bygger på att alla kostnader läggs i boendelandet. Vidare utgås det ifrån att båda familjerna har samma konsumtionsbeteende som en genomsnittlig svensk tvåbarnsfamilj med jämförbar inkomst.

This study was carried out as a commission from Holmen Skog, district ?Egen skog? in Norrköping. During October 2006 several stands were inventoried by aerial photos from helicopter. The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.

Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.

The aim of this thesis was to find out how the teachers I have interviewed, felt that they worked with and looked at conflict management. The aim was also to find similarities and differences in teachers' ways of working with conflict. With the help of my questions, I got answers to what I wanted to explore in my essay. I used these questions: What strategies do the teachers I interviewed for managing conflicts in preschool? What tools do the teachers I interviewed see as most effective in the process of conflict management? Are there differences and similarities in the way that the teachers I interviewed work with current conflict? What factors, according to the informants starts a conflict? What is the teachers? definition of a conflict and how does their definition affect their approach when working with conflicts?In my study, I have used a qualitative approach in the form of structured interview, to get material for my thesis.

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.
