Statuskontroll av Paradisskolans elektriska belastning

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.

En Kommunikations Illustration : Interaktionen mellan deltagare i ledarlösa samarbeten

Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.

Sekundärnät för lågtempererad fjärrvärme

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

Intellectual Property Rights in Software : A Critical Investigation from an Ethical Perspective

The development of software was considered until the beginning of the 1990th as a cathedral like product development in closed companies. This way of development changed in the last decade. Open source software (OSS) development challenged this consideration significantly. OSS is produced in co-operation by skilled people, distributed and used by many moral agents. The result, the software itself, can be studied and modified.

Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

SYNS VI I SVERIGE? : En rättssäkerhetsstudie om barn i migrationsprocessen

The current thesis is on the rule of law and how the principles of the rule of law are met in thenew Swedish migration process. The migration process has been subjected to criticism duringseveral years and on different occasions. The migrations process is viewed through a ?rightsof the child? perspective, foremost to seek if the rights of the child are met. The children are avulnerable group, not the least in the process of migration.

Är plöjningsfri jordbearbetning bättre än konventionell plöjning? :

The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.

Utveckling och utvördering av statistiska metoder för att öka träffsäkerheten hos lokala vindprognoser

Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.

Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer

This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.

Myt och vetenskap om kastration av tik

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

Alkoholmissbruk på arbetsplatsen -När är det grund för uppsägning?

Abuse of alcohol is one of the biggest problems that society faces today. There are between three and four hundred thousand abusers in Sweden. In addition there are about three hundred thousand over consumers. The government bill proposed in 1977 gave the labour market most of the responsibility to solve the problem. They thought a meaningful job and a spirit of community were the most important factors to decrease abuse of alcohol and social rejection.

I say, good sir! Jag säger då det, min bäste herre! : Översättning av akt I-IV ur pjäsen London Assurance av Dion Boucicault samt översättningsvetenskaplig kommentar och undersökning av avsidesrepliker i svensk- och engelskspråkigt drama

This masters thesis consists of a translation of acts I-IV from Dion Boucicault?s play London Assurance, a theoretical comment on the translation and a comparative study of asides. It is divided into four parts: an introduction, presenting the work and my translation strategy, as well as a short stylistic analysis; source text and translation; a theoretical comment, mainly based on theories from the field of Translation Studies, but also theories on lingustics and literature; and a comparative study of the use of asides as a theatrical convention in English and Swedish drama.The main focus of my translation strategy is to keep or adapt features that give the audience a sense of the cultural context where the play takes place, as well as the time ? fashionable society in early Victorian England, while providing a text that is performable and speakable for the actors, and which preserves the humor present in the source text. .

Europeiska arkivhandlingar : Europeiskt identitetsskapande i samtida ABM-projekt

The aim of this master?s thesis is to analyse the construction of European identity in three ofcontemporary EU initiated projects for the digitisation of collections from museums, archives, andlibraries. The source material consists of the web pages of the projects Minerva, MICHAEL, andEuropeana, as well as some other policy documents on digitisation and access from EU authorities.Theories on nationalism and construction of heritage are used as an overall context to the problem.After a brief description of the mentioned projects, the author undertakes an analysis of theways that the concept of ?European heritage? is depicted in the source material. The result is thefollowing: normally, the true European heritage is considered being united even though it isdiveded culturally, historically and linguistically.

Working Veterinary Nurses and Veterinarians have been surveyed to find out what they think the responsibilities and education of the Registred Veterinary Nurse should be..

"Man kan ju hitta i princip allt man behöver på Google" : Högstadie- och gymnasielevers informationssökning i digitala medier

The purpose of this essay is to examine how high school students (age 13 to 19) search for information on the web and in databases. Furthermore, it aims to look into how critical of sources they are. The questions asked was: how the students search for information in digital media? Which kind of sources do the students use? How they evaluate the information they find? Do they get any education in information retrieval and source evaluation? To answer these questions students were interviewed in groups about their information retrieval behavior. Furthermore two school librarians were interviewed about their experience of the students? information retrieval.During the interviews it was clear that the students had received quite sparse instructions on the subjects of information retrieval and criticism of the sources.
