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.

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.

This study analyses the economic consequences due to ethanol production in Eastern Sweden. The analyses consider the cooperative and the farmers as one vertically integrated company. The area that found the market in this study is illustrated in figure 1. The analyses assume that all members act jointly with the objective of maximizing joint profits at the farm level as well as at the cooperative firm. A mathematical model is created to calculate the optimal use of arable land.

The purpose of this of this essay is to explore the construction of a conservatory that is livable allyear around. When you build a conservatory there are several factors that need to be regardedthat usually are of no importance when you build a regular conservatory. The glassed facadeneeds to have a very good U-value and all the parts of the facade need to be isolated and theconstruction needs to prevent thermal bridges.In this essay we will start by looking at the shape of the conservatory. Due to the façade consistsof glass the conservatory will need to have a good ratio between the area and the façade so thatthe heat losses will be at a minimum. However, due to the fact that one of the sides of the façadeis connected to the warm house, you quickly realize that the shape of the conservatory is of noimportance.There are two common ways to build a foundation for a conservatory, a molded concretefoundation and isolated wooden beams.

The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 ? 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel.

Arbetet handlar om analys av staden och behandlar frågan om hur man kan analysera staden på ett så heltäckande sätt som möjligt. Jag har använt två olika analysmetoder: Realistisk stadsanalys och Finding lost space. Dessa två består i sin tur av flera mindre delar där olika infallsvinklar ges spelrum. Analysen ska leda fram till ett konkret planförslag, och arbetet behandlar därför hela analys- och designprocessen. Arbetet har organiserats utifrån en arbetsmetod med fyra steg: Historiska studier; Analys av stadens nuvarande rumsliga sammanhang; Syntes samt Planförslag.

The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis..

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..

Syftet med denna uppsats är att försöka klarlägga rättsläget kring vissa ränterättsliga problem. Problemställningen har således främst kommit att handla om Räntelagen, en dispositiv lag som reglerar både tidpunkten för och omfånget på dröjsmålsräntan som skall utgå i olika situationer. Av de tillgängliga rättskällorna var rättspraxis den mest viktiga .I uppsatsen kunde med hjälp analys av ett sådant bla vissa avsteg från Räntelagens § om avkastningsränta anas. § 4 st. 2 fanns också inte tillämplig i fallet av oklara proprieborgensförhållanden.

Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.

The purpose of this essay is to analyze and understand the effects that a recession can have on a company?s marketing department. In times of a recession most companies have less means to promote their products to their target market and to build their brand. This means that cutting the marketing budget will show some effects on today?s way of marketing.

För bestämning av slänters stabilitet tillämpas traditionellt klassisk analys där säkerhetsfaktorn F beräknas. Underskattning av jordmaterials hållfasthetsparametrar gör att denna beräkningsmodell kan leda till resultat på den så kallade säkra sidan, det vill säga att det eftersträvas en säkerhetsmarginal mot brott. Detta kan i sin tur exempelvis leda till att eventuella förstärkningsåtgärder blir onödigt kostsamma. Ett alternativ till det klassiska förfarandet är probabilistisk eller sannolikhetsbaserad analys där istället sannolikheten för brott beräknas. Detta avser sannolikheten att säkerhetsfaktorn är lägre än ett visst kritiskt värde.
