Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

This thesis is a qualitative study in which 12 award-winning printed adverts, awarded with either a Swedish ?Guldägg? or an international Clio Award, have been analyzed from a rhetorical perspective. Visual rhetorics were used to analyze the adverts in order to expose the rhetorical concepts and to find out whether the rhetorical concepts represented in the Swedish adverts are the same concepts represented in the international adverts. One of the conclusions drawn is that pathos-arguments, a rhetorical concept where the senders allude to the emotions of the receivers, are the most prominent in both Swedish and international adverts, but are used in different ways. Another conclusion drawn is that the adverts are overall characterized by their messages not being explicit.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Syftet är att evaluera Baselramverkets riskreglering i en konjunkturcykel med hänsyn till Östersjöregionens storbankers systemviktiga funktion.Studien antar främst en kvantitativ ansats i de två första delarna, nyckeltalsanalysen och buffertsimuleringen men även en kvalitativ ansats antas i den tredje delen, intervjuer. Studien utgår från teorierna om Basel I och Basel II, nyckeltalsteori samt från tidigare forskning.Resultatet i studien består av nyckeltalanalys och simulering av åtta, i Östersjöregionen verksamma, bankers nyckeltal och buffert under 21 år samt sex djupintervjuer med representanter för såväl banker som regulatorer. SlutsatserAtt det inte finns något samband mellan Baselregleringens kapitaltäckning och bankernas risk eller konjunktur, att riskvägningen tenderar till att vara godtycklig och har större påverkan på buffert än Baselregleringens kapitaltäckning samt att mer transparens behövs i bankerna tyder på att Baselregleringens kapitaltäckningskrav i mycket liten utsträckning visar Östersjöregionens storbankers faktiska risk..

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

This is a qualitative study of how some journalists on the Swedish national media are using social media in news work. The study, carried out by using interviews, also covers how these journalists' work is influenced by social media. For the journalists in the study social media has become a tool to do research, get news ideas and find interviewees. At the same time social media affects the work of the journalists, as the social media increases the speed of news and flow of information. Even though they involve some challenges, social media facilitates news work and the journalists in this study have a positive attitude towards the phenomenon.Keywords: Social media, news journalism, the national media..

Purpose: The purpose of this thesis is to test for the existence of Capital Structure Arbitrage oppertunities in the equity-credit markets. Methodology: The mispricing of Credit Default Swap contracts are calculated and used as input in an Equity-Credit market trading strategy. The returns are then evaluated with a modified Value-at-Risk simulation. Theoretical perspectives: A Merton-based structural model, CreditGrades, is used for credit pricing and a mispricing-convergence trading-strategy between the credit and equity markets is implemented. Empirical foundation: Daily quotes for the Credit Default Swap spread of 37 European firms were collected for a period of two years, as well as equity-prices for the same period and the previous two years, used for model calibration.

Climate changing is a growing problem for many countries and communities over the world. The cities has a huge work to deal with in their reforcements of their cities to be resilient ones. This thesis makes an effort to investigate and illuminate some of the problem the cities has to solve related to flooding, hazards, erosions, rising sea levels and crotches. This thesis will help to find solutions that international and national efforts has produced and handed out to each other. A lot of communities are charing their excellent tools that works for them.

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.

The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.

The market offers more and more products that are claimed to have medicallypositive effects (like increased blood perfusion etc.) due to their magneticproperties. The objective of this study was to investigate if blankets containingpermanent (static) magnets have a greater impact on cutaneous blood circulationthan ordinary blankets without magnets. Eight standard bred horses were used in across-over study. The cutaneous temperature was presumed to reflect blood flowin the skin and therefore thermography and local thermistors were used to indicatechanges in circulation. Baseline values were registered before the blanket wasapplied.
