The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife. The methods used for costcalculations regarding piping are alsoto be examined to highlight thedifferences between template basedcalculations and more carefully executedones. The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

The purpose of this project is to study Partab's material distribution process, furthermore identify critical problem areas within the company. Further the aim is to provide suggestions to new work procedures regarding material distribution and related processes. Appropriate literature has been used as a support in this process. The main goal of a commercial company is to generate cash flow, and maximize the return on investment. Streamlining material supply and the use of material is a part of this process. Virum and Persson define logistics as: "Logistics is the approach and principles founding the process of planning, development, coordination, organisation, management, and control of material distribution from supplier to user".

The company is owned by the munici- pality of Falun and manages community services in electricity, district heating, fresh water, sewerage, metropolitan area network and waste disposal. The following theories have been used in the study: convergence culture, digital natives, information overload, communication strategies and uses & gratifications theory. The methods used in the study are 4 focus group interviews and one informant interview. The members of the focus groups where within the age range 18-29 years and lived in the city of Falun.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.

To extend and verify the conclusions drawn, another company, AB Ph.

The aim of the study is on basis of Peters and Waterman?s factor of success, to examine the successful companies, Ericsson and Huawei, and to analyze the R&D and positioning strategies of the companies.To accomplish the study we have used a case study using interviews and annual reports to collect data. Three persons have been interviewed, two from Ericsson and one from Huawei. All annual reports from the year 2004 until 2011 have been reviewed.Our finding is that Ericsson and Huawei do not, according to Peters and Waterman?s model, fulfill all factors of success and their R&D strategy varies depending on the situation and which knowledge the company already possesses and needs.

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.
