This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system.

Symbolic resources transform in to social power and material resources through the educational system. This entails that all students should have equal access to it.The essay compares Swedish didactics in ?immigrant? and ?white? schools, all situated in socio-economically underprivileged areas, analysing interviews with eight Swedish teachers about their didactics regarding restricted and elaborated language code.Understanding teacher?s work in the class room requires attention to the intersections between race and class, and of both to the distribution of symbolic resources in general.The essay finds that the practice of the? immigrant? school teachers differs from the ?white? school teachers?. The former are active, providing intellectual tools, scaffolding and driving force while the later choose a more passive attitude, letting students decide for themselves what to do and what goals to reach. Consequently ?white? schools allow the reproduction of unequal distribution of symbolic resources while practice in immigrant schools aim to compensate for disadvantages.Practice seems to win legitimacy by different sets of conceptualisations.

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Kraven på att nybyggda bostäder ska vara energisnåla i driftskedet ökar hela tiden av flera anledningar. Dels vill brukarna hålla driftskostnaderna så låga som möjligt och dels är det miljöaspekten som spelar in. Men hur energisnål kan en villa egentligen göras och hur påverkas arkitekturen då den görs extremt energieffektiv?I den här rapporten utreds tio energieffektiva principer som kan användas för att göra en villa mer energisnål och energiproducerande. Alla tio principer har tillämpats i en villa som projekterats under arbetets gång.

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

Purpose/Aim: Exhibitions in cultural-historical museums have traditionally been object-centered and associated with one-way communication. The aim of this thesis is to gain knowledge about how exhibition producers ? and educationalists at swedish cultural-historical museums today relate to communication in exhibitions from a communication scientific perspective.Material/Method: The method of the thesis is interviews exhibition producers ? and educationalists at five swedish cultural-historical museums about how they work with communication issues in exhibitions. The empiricism gained from the interviews have been analyzed from a communication scientific angle, using two communication theories as idealtypes for communication processes; Shannon and Weaver´s model and Stuart Hall´s encoding/decoding-theory.Main results: Communication in exhibitions have developed, much due to the use of more channels for communicating with the visitors and the acknowledgement of the visitor as an active subject in interpreting the exhibitions and their message.Despite this development, communication in exhibitions still have features of a one-way communication. The main feature is the lack of possibilities for visitors to communicate their interpretations and point of views of the exhibition back to the exhibition producers.

In this study we have aimed to explore how participation and self-determination is implemented in the daily life of disabled people who receive support through LSS. The questions addressed concern possibilities/obstacles for the participation and selfdetermination of disabled people who live in group housings, and how the terms participation and self-determination are realized. Nine interviews have taken place with staff members and directors of different group housings. We have found that the interviewees believe that the nature of a person?s disability can be a barrier to the individual?s self-determination and participation in his or her everyday life.

The challenge that companies currently face in their attempts to break through the media clutter has resulted in an increased use of provocative advertising worldwide. History shows that this strategy can result in a brand crisis due to negative consumer sentiment. Despite this fact, advertisement generated crisis remain a relatively unexplored field in the academic world of marketing. The objective of this thesis is to further explore crisis creation from provocative advertising, evaluate the affiliated negative consumer consequences, and to examine the effects of two contrasting company strategies to remedy these types of crisis situations. An experiment was conducted on Swedish and Norwegian students in order to examine whether the communication and information sharing between the target consumers and others could explain the development and consequences of provocative advertisement crisis due to its psychological effects.

ABSTRACTIn this study I have analyzed, throughout a gender perspective, two textbooks Den levandelitteraturen and Upplev litteraturen which are purposed to be used as teaching materials inSwedish schools in the subject of Swedish when teaching the history of literature. The intentof this study was to provide a gender analysis of two textbooks and the focus was on thepresentations of female and male writers, because they have not been studied earlier. In thisstudy, a qualitative text analytic method was used to achieve the best results as possible.Theories used in this study were Yvonne Hirdman?s and Raewyn Connell?s theories. Hirdmanclaims that there are differences between men and women at different levels in the societywhile Connell believes that this is a myth because, according to her, men and women arepsychologically alike.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

In this paper the authors are trying to understand what separates men from women when they save and invest their money. But also what factors that influence them in their decisions. To investigate how men and women actually act when investing their money the authors construct a survey. The authors also turn to the Swedish banks for information on how they think there customers are behaving. The authors find that men are more risk- taking than women and therefore invest more in products with higher risk, for example shares.
