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.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.

Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).

This paper analyses education regarding its profitability from an individual?s perspective. The method for conducting the analysis is an ex ante cost-benefit analysis and the time period examined is between the days the education begins until retirement age. The conclusions of this paper are that tertiary education is not profitable for an individual given the conditions stated in this examination. Furthermore the longer the education lasts, the more unprofitable it is.

This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

In modern society globalisation is a fact within all industries, the textile industry included. Due to improvement in areas such as logistics and communication international trade have developed fast. As changes occur rapidly on the global market and companies must adjust and revise their processes in order to stay competitive.Because of the global price reduction consumers around the world expect low-price products, which mean that the companies have to find new ways to produce in a cost-efficient way. To maximize profit most of the textile production is situated in low-cost countries due to its labour-intensive character. It is crucial for fashion companies to allocate their activities in their value-chain effectively in order to reduce lead-times.

The purpose of this study was to gain a better understanding of how medium-sized construction companies adapt and how they choose to reorganize their operations in relation to the recession. The study has as its theoretical starting point theories about organizational learning, the impact of the economy on construction companies and strategies for dealing with recessions. The method used to conduct the study was semi-structured interviews with representatives from 15 different construction companies. The results of the study show that they used several strategies to adapt and reorganize the business in accordance with the recession. Some construction companies had to make cost savings as a result of the recession.

Compared with a few years ago, the cost of concentrates has increased substantially and because of that an increased proportion of pasture is of interest. Pasture is cheap and the farmer does not have to harvest when the cows do it themselves by grazing. This saves both money and time. According to research milk yield decrease with an increasing proportion of pasture in the diet. This is because cows on pasture will have lower dry matter intake than cows with supplements.

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

Examensarbete i Ekonomistyrning, 30hp, Ekonomihögskolan vid LinnéuniversitetetTitel: Kalkylutveckling i tillverkningsindustrin ? en fallstudie hos HordaGruppen ABUnder 1980-talet uppmärksammades kalkylmodellens roll som ekonomiskt styrverktyg. Denna uppmärksamhet ledde till omfattande studier av hur kalkylmodeller kunde utvecklas för att lättare klara av förändringar i företags inre och yttre förutsättningar. Kalkylmodellers utformning påverkas av ett stort antal faktorer som t.ex. strategi, kontext och användning.

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.
