Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Teachers in social sciences have a broad subject field to base their education on. This term paper examines, thru interviews, which factors that have an influence on the subjects contents in the A course of Social Sciences at Swedish high schools. Having interviewed four active teachers at three different schools, it shows that control documents like subject- and national curricula have little to say about what kind of subject that should been taught. Teachers seem rather to rely on local collegiate consensus, the textbook, locally prepared control documents, and adjusting to program directions while choosing material. In the final discussion the risk of structuring the subject around the text book is being investigated, along the fact that new locally control documents need to be written even for basic planning structures.

The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991). A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations. Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012). Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).

Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

Uppsatsen syftar till att besvara vilka de värdedrivande faktorerna är inom onlinespelbranschen, samt att undersöka om onlinespelbolagen är övervärderade. Den empiriska studien omfattar tre bolag; Sportingbet, Betandwin och Unibet. Avgränsningen till dessa bolag motiveras med att de är vägledande företag som bra skildrar utvecklingen och därmed får representera branschen. Det är framförallt två parametrar som författarna finner extra viktiga för att skapa värde i onlinespelbolag, det är spelöverskott och antalet aktiva kunder. För att jämföra bolag inom onlinespelbranschen har författarna därför komponerat två nya relativvärderingsmått; Price/Gross Profit och Price/Active Customer.

Environmental impact and management of energy is a highly topical issue in today's society. Climate impact must be reduced. The Government has set a target to reduce energy consumption in buildings by 20 % by 2020 and 50 % by 2050 compared to the energy use in 1995.With this in mind, we chose to examine how property owners can work on improving energy efficiency in existing apartment buildings. We also wanted to investigate profitability of different increasing energy efficiency measures and the calculation methods and the risk assessment performed by such investments. To tie in with government objectives, we also saw the possibilities of achieving these goals.20 companies were interviewed, of which 14 were property owners and 6 were consulting firms that works with energy efficiency.

The aim of this Master's thesis is to examine how blogs are used by public libraries for marketing purposes, and how librarians who blog perceive their blog as a marketing tool. The thesis is based on a qualitative study conducted using asynchronous e-mail interviews with librarians representing eleven different library blogs. The theoretical framework and concepts are taken from marketing theory, including Kotler's marketing mix, relationship marketing, and theories on the marketing of non-profit organisations, knowledge organizations, the Internet, and blogs. Our results and analysis reveal that libraries use blogs because they are an easy tool to use, they represent a new way to inform users about the library, they are a way to improve contact with the users and a way to reach potential users. According to the librarians we interviewed, blogs can be used to market libraries in a number of different ways: by disseminating information on the library and its various media and events, by providing a forum to demonstrate the skills of the librarians, and as a way of changing the image of the library.

This study focuses on the transfer between a product-oriented to a service-oriented perspective regarding marketing activities in companies due to the development of information technology. It illustrates how this very transfer has been, and can be, contemplated through the eyes of organizations working with marketing in a digital world on a daily basis. Technology has turned several industries - their price-setting, communication channels and supplying possiblities - upside-down. This turnpoint brings out a new way of observing and working with marketing. Therefore, we find it interesting to gain a better understanding of how actors within industries where the turnpoint is a fact observes marketing, and how this service perspective can be seen in their various organizations and daily.

The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.
