Anonyma Alkoholister : Vilken inverkan självhjälpsgruppen har på gruppdeltagarnas välbefinnande
AbstractWe are interested in group meetings of the self-help group Alcoholic Anonymous and the emotional energy created therein. We examine which impact self-help group AA has on its group participants regarding: group meetings, dealing with alcoholism and identity. Group membership has great value for individuals; it provides social identity and possibility to self-value. Previous research shows that group members of self-help groups who have been sober for a period of time experience higher self-esteem and less anxiety compared to non-members. Our thesis is based on a hermeneutic approach.
Jämförande studie av LEM2 och Dynamiska Redukter
This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.
En balanserad rapport? Om svenska medier i Egyptens andra revolution
This bachelor thesis is a critical study in which we are studying if the swedish reports of the so called ?second revolution? in Egypt have been objective. We have been studying this by using Jörgen Westerståhls objectivity model and we have chosen to investigate whether the reports have been objective balance-wise. The second revolution is a term which describes the protests and demonstrations that led to the military action in which the elected president Muhammad Mursi were forced to resign on the 4th of July, 2013The study includes articles from five leading Swedish newspapers, Aftonbladet, Dagens Nyheter, Expressen, Göteborgs-Posten and Svenska Dagbladet. We have been studying all the articles that include the word ?Egypt?.
Energieffektivisering i flerbostadshus : Undersökning av lönsamheten med energieffektivare ventilation

Vinster med återvinning, Stena Recycling
This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.
Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige
Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.
Månadskostnader vid investering i ny bostad : En jämförelse av olika investeringsalternativ och deras ekonomiska påverkanvid införskaffning av ny bostad.
This is a work that look at the factors that affect future monthly costs when buying a house in Sweden and which options are the most financially favorable over a 30 year period. The work also examines whether it is economically beneficial to invest in a low-energy house regardless of geographic location in Sweden, and discuss about whether a calculation template can help individuals to choose more environmentally friendly options. The work has been limited so that a certain number of predetermined factors and its measurable values have been developed with the help of a literature study. The factors chosen are building type, climate, heating systems, loan interest rates, energy prices, energy price increases, inflation rates and down payment. These are then combined into 72 different calculation cases which get put in a calculation model made in excel.
Elimineringen av korridormetoden - Hur svenska företags nyckeltal påverkas
In 2011 the International Accounting Standards Board issued amendments to IAS 19 Employee Benefits. The new standard is effective from January 1st 2013 and one of the largest changes in the standard is the elimination of the corridor method. Through the corridor method companies had the possibility to defer actuarial gains and losses resulting from their defined benefit obligations (pension obligations) and leave them unrecognized off the balance sheet. According to the new standard companies reporting under International Financial Reporting Standards will have to recognize all actuarial gains and losses immediately in other comprehensive income. The aim of this thesis is to examine how the financial key ratios of Swedish listed companies will be affected by the elimination of the corridor method.
Energieffektiva principer : Påverkan på en villas arkitektur och energiprestanda
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.
Finansiering av vindkraft : fallstudie av Lau Vind AB
The wind power increase of Gotland as well as other parts of Sweden during the last ten year period has meant that this renewable energy source has increased its share over other fossil sources. The year of 2011 became the first when the wind power produced more energy than an average nuclear reactor. Now that wind power is in an expansive phase, the land issue will be of great interest. Land with good wind resources will be of interest to wind energy developers. The problems that this essay is based on are; how can landowners altering the economic conditions at a wind power establishment? What opportunities and obstacles exist for landowners who choose to set up wind power on their land? The purpose of this essay is to highlight the economic conditions that exist for landowners for the establishment of wind farms, with regard to compensation for the leasing and return on invested capital.

Skiftande maktbalans? : - en analys av det nya EU-fördragets konsekvenser för EG-domstolen
ABSTRACTUniversity: Växjö University, school of social science, department of political scienceLevel: Bachelor?s thesis in political scienceTitle: SHIFTING BALANCE OF POWER? ? an analyze of the new EU-treaty?s consequences for the EC-court.Academic adviser: Associate professor Stefan HöjelidAuthor: Magnus NordahlThis study focuses on the increased role of the European Court of Justice through the establishment of a Constitution for Europe and its impact on the balance of power, both horizontal and vertical.To do this, the study takes its aims from the research problem, formulated as follows:Does the establishment of a constitution for Europe contribute to an increased role for the European Court of Justice and does it create a more legible horizontal and vertical division of power?To reach the relevant analyses and conclusions two precise questions are presented as well as an analytical model. The precise questions are:? Which are the relevant contributions for the balance of power from a perspective of juridification in the new EU-treaty?? What impacts do those contributions have on the so called ?European federalism??The theoretical perspective of this study is rooted in the concept of federalism with special emphasizes on constitution and sovereignty as well as a part about the process of juridification. Along with the presented analytical model consisting of a horizontal and vertical division of power, the empirical material is presented with focus on the new EU-treaty about a constitution for Europe and the European Court of Justice.
Lumilos
Lumilos is a work investigating the possibilities to use light and color in an interactive design context.
I have explored different light sources and compared them to each other and given a short
description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms.
I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.
Driftoptimering av torkmaskin : Driftoptimering av torkmaskin 3 vid Billerudkorsnäs Karlsborg AB
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Värmeåtervinning på förskolan Rymdattacken 1 : En jämförelse av värmeväxlare
In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.
