The background for my thesis is the fact that with rising electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work. The main objective for this study is to compare three different heating systems to decide how they differ considering effort and cost. The result from the calculations was that grain-heating system demanded the least amount of work, but the total cost was a little higher compared to chips heating. Chips heating required half as much work as today?s wood heating and had a little lower total costs compared with the corn heating. Which system to choose largely depends on how the own work is valued.

The use of ERP in organisations is very popular and many companies have embraced this paradigm without really questioning why. Problems therefore often arise and cause high costs which is a result of poor planning. The paradigm also has its origin in the traditional architectural design that creates a system that has difficulties to adapt to organizations that are constantly evolving. The purpose of this study is to provide a different view of how IT-systems can operate within an organization and show how standard systems can be structured. We emanated from a case study at Linköping University Library, where we studied the implementation and integration of a standard system called Symphony.

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

En stor del av tiden vid utveckling av programvaror går idag ut på att leta efter fel i dem. Oavsett hur mycket tid och pengar som läggs ner på denna aktivitet är det inte säkert att alla fel hittas. Detta kan få katastrofala följder, speciellt för realtidssystem då även fysisk apparatur skall skötas. Då ett fel verkligen har påvisats gäller det att försöka lokalisera och identifiera felet. Då detta kan ske under tidspress, till exempel om felet rör ett realtidssystem redan i användning, behövs stort stöd från felsökningsverktyg för att underlätta att snabbt lokalisera och identifiera ett fel.Detta examensarbete identifierar genom en teoretisk undersökning ett antal riktlinjer för de stöd ett felsökningsverktyg kan ge felsökaren under felsökningsprocessen.

Antalet flygresor har ökat markant i världen de senaste decennierna. Detta har medfört en ökning av flygets koldioxidutsläpp som därmed har gett en ökad påverkan på klimatet. Forskning angående människors syn på och uppfattning om flyget är relativt ny och forskning rörande ämnet är mer förekommande idag än för ett decennium sedan. Tidigare undersökningar är dock i stort sett eniga om att människor, både miljömedvetna och icke-miljömedvetna personer, inte tänker ändra på sina flygvanor och flyga mindre på grund av flygets klimatpåverkan. Denna studie undersöker klimatengagerade personers flygvanor och vad de har för syn på flyget och flygets påverkan på klimatet.

The increase of complexity in embedded programming is forcing the development of higher level programminglanguages. These languages not only consist of traditional text based programming but also with graphical programminglanguages such as the programming language G from LabVIEW which is developed by National Instruments and havebeen around since the mid eighties. However since 2004 this language has also been able to program embeddedhardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts itsgraphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and consof using G for embedded development.

This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.

The aim of this study is to evaluate an alternative projection of the Medial Coronoid Process (MCP) of the canine elbow joint. The projection (Di35M-PrLO) was, to my knowledge, first mentioned in an article by Haudiquet et al in 2002. In that article the projection was tested in vitro, and a good sensitivity was showed for the Medial Coronoid Process. The projection might be helpful in cases of suspected Fragmented Coronoid Process (FCP) . This study is divided into three parts. The first part is an in-vivo test of the projection, including technique and subjective evaluation of the outlining of the MCP.

Purpose The purpose of our study was to investigate the changing nature of volatility during the last 80 years. Like in an American study, we tried to find some trends in the risk of stocks and bonds that would have an impact on the balance of a portfolio of stocks and bonds. At the same time we investigated the influence of inflation on the choice of portfolio. Methods We have used standard statistic tools and formulas to obtain our results. In most cases it was a matter of calculating average and standard deviation.

Sustainability reports have during the last decade had a strong development. Both in terms of establishing a sustainability assurance, in its form, and get it assured together with standards, principles and regulations which organisations and accountants have utilized. The growth of sustainability reports and the choice of getting them assured have in particular favoured the accounting business. Due to this result, some critics have voiced that assuring a sustainability report gain accounting firms more than it gains the actual organisation. Other say that it is necessary in order to increase the credibility and the eligibility of the report, while it also has become a requirement from stakeholders.

This report intends to analyze the difference between the original rules and a modification of the rules for the Scandinavian version of the world famous dice game yatzy (yahtzee). Several works are made previously existing strategies for yatzy and Yahtzee.The study was conducted using the optimal strategy calculated and implemented in the programming language Java. The execution of the application to create the file containing the optimal strategy was running on leased powerful servers from Amazon and took just over six hours each.A simulated player played 100,000 games based on the strategy, to obtain data which then was used to plot graphs and analyze the expected score and its standard deviation. The expected value (mean) and standard deviation of the score for the possibility of three or four throws were 233.00 ± 44.82 and 280.07 ± 41.25.In view of the results drawn the expected conclusion that the four possible throws provides increased probability of getting a high score, unlike the case where the player may only be able to throw the dice three times. The fact that the variance is lower in the case of four throw session is equivalent to that the likelihood to get close to the expected value increases..

The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A). The main purpose with this report is to look at three questions: 1. How does the supply chain look today? From forest to industry. 2.

During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) needs to take all these perspectives into account while planning new investments. To compare and relate perspectives of technology, economy and environment the same yard stick must be used. That yard stick is commonly money. A problem arises however as environmental issues are difficult to price.The purpose of this master?s degree project was to develop a tool for evaluation of environmental impact related to investments in the Swedish national grid.

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

The aim of my study is to answer the question whether there is a potential for services by working horses in the Swedish municipalities. The Swedish University for Agricultural Sciences (SLU) and Swedish Farmers Union (LRF) has started a cooperation called Climate School (Klimatskolan), with the purpose to increase knowledge in environmental and climate related issues in context of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a big responsibility concerning environmental work and to develop their own environmental thinking.
