The background to this paper is the fact that many products are demonstrated to show the consumer value of the product. This is generally the fact when it comes to agricultural products, such as tractors. The growing number of models makes this even more import for the retailer to perform a demonstration that really catches the interest of a prospect customer. One problem is that these demonstrations are expensive and many small retailers have difficulties to afford demonstrations of every model. Together with Åhmans Traktorcentrum AB a market investigation was conducted. The company has its primary sales area in the region of Östergötland and north part of Småland. Åhmans Traktorcentrum AB is a John Deere dealer.

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

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.

In this thesis is studied the electrical load of Paradisskolan with respect to power quality and energy consumption. The school's owner Trollhättans Tomt AB is also interested to know if they can reduce their costs by changing to smaller meter fuses. A recurring ground fault that?s been recorded from powerpanel A1A has been investigated. The school's equipped with an electrical bonding system, harmonic filters for the third harmonic currents, TN-S system from feeding transformer and groundfault monitoring.

In the year of 2009 the conditions for managing primary healthcare in the region of Västra Götalandchanged. The decision was taken by the regional assembly and resulted in that the citizens since thenhave had the opportunity to choose which health care provider they preferto stay with. Along with thisdecision a new market for private health careproviders was established, which resulted inincreasedcompetition between the providers.In order to manage the competition, the health care providers arenow forced to be more efficient in their operations andalso to beeven more focused on their patients.Backa Läkarhusgruppen is an example of a private healthcare provider in the region of Västra Götaland.In the same way it is also an example of anorganizationin need of analysing their operations to seehowit can be further optimized to meet patient needs and expectations.The aim of this study is to analyse Backa Läkarhusgruppen?s organization and its operationsin the hopeoffinding suggestions whichwill improve the patient flow.To allocate and solve the problems thatBacka Läkarhus suffer from,an approach inspired by Lean Healthcare is used throughout the report.Some of themost significant problems that were identified within the organization are:?The synchronization of demand and capacity is inadequate.?Absence of standardized routines.?Absence of present leadership.To be able to improve the patient flow Backa Läkarhus needs to handle these identified problem areas.By synchronizing the staffing level in relation to the trends in demand a reduction in the patient?swaiting times and throughput time will be possible. Creating clear responsibilities and routines for thestaff will contribute to a higher degree of patient focus and thus lead to a more efficient patient flow.

The homes that were built in the 60?s - and 70's are now so dilapidated and worn that they need thorough renovations. These renovations are expensive to implement for the landlords, which means that the funding for these renovations can create problems. Currently there are no government subsidies for these renovations. This report will examine how Förbo performed the renovation of Säteriet.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

Purpose: To examine how video-game releases affect the share price, and if video-game reviews have any impact on the share price of gaming corporations. Method: A quantitative deductive research approach is applied with event study methodology used as basis. The investigated companies were the five largest gaming companies listed on the U.S. NASDAQ exchange. A total of 29 video-game launches and 85 reviews where examined.  Theory: The study is based on The Efficient Market Hypothesis, Agent Theory, Public Relations Theory, Nextopia and previous research.Results: The result contains 114 observations in five companies.

Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.

The 100 MW goal, combined with Uppsalahem?s environmental policy, is a strong incentive to investigate the possibility of installing PV modules on the many available roof areas that Uppsalahem possesses. The objective of this thesis is to create a foundation for future decisions regarding PV systems for Uppsalahem.

Hur publika displayer skall utformas och anpassas efter sin miljö på bästa sätt är ännu ett outforskat område. I takt med att miljöfrågor blivit än mer aktuella i dagens samhälle har det också etablerats ett behov av att förändra vårt beteende exempelvis i form av energieffektivisering. Syftet med denna uppsats är att undersöka hur en publik touchdisplay för elvisualisering skall utformas för att vara förståelig, intuitiv och säker från publik genans. En användarstudie i form av en utvärdering av en interaktiv touchdisplay kallad Urban Energy monterad i Göteborg har gjorts under ledning av Interactive Institute Swedish ICT. Touchdisplayens primära syfte är att uppmärksamma förbipasserande på stadens elförbrukning och uppmuntra till energimedvetenhet.I denna studie rekryterades 17 förbipasserande deltagare villiga att testa denna display med hjälp av två uppgifter och en enkät.

Under 2011 började MacBat AB ta fram ett elenergilager kallat Macbat Energy Storage System (MESS), vilket är uppbyggt av 360 stycken tvåvolts bly-syrabatterier inhysta i ett 20 fots container. Då bly-syrabatterier är känsliga för värme är den här studien inriktad på att utreda hur stort kylbehovet blir under olika förutsättningar där kyldistribution, drifttemperatur på batterierna, klimat, isolering och termiska tröghet är varierande parameterar. Det ska även avgöras vilken konfiguration av kyldistribution och isolering som ger lägst kylbehov för de studerade klimaten, vilka är av varmtempererad, arid och tropisk karaktär.För att besvara studiens två mål togs fyra matematiska modeller fram i SIMULINK. Två luftkylda och två vattenkylda där en av varje var isolerad med 100 mm mineralull medan den andra var oisolerad. För samtliga modeller varierades drifttemperaturen mellan 25 ? 35 °C och de studerade klimaten utgjordes av Phnom Phen, Kambodja, Djibouti, Djibouti, Bagdad, Irak samt London, England.
