Framtidens energieffektiva flerbostadshus
The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.
Att Synliggöra det Osynliga : GIS som verktyg i sökandet efter bosättningsområden från bronsåldern på Gotland
In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.

Opiatberoende och läkemedelsassisterad behandling : En kvalitativ studie om några socialarbetares syn på opiatberoende och behandling med metadon/subutex
The aim of this study is to take note of social worker´s views on opiate addiction and medication-assisted treatment. The definition of social workers in this paper, is people who are involved with individuals who have an opiate addiction and have therefore been in contact with drug assisted treatment. Data was collected through interviews with social workers. The interviews were based on an interview questionnaire on four explicit themes: Motivation, Medical Assisted Treatment (LA) Other complementary treatment and expenses and its meanings. These are analyzed and discussed through the theory of harm reduction and the theory of labeling..

Maskinskydd på rullriktverk
ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.
Har ungdomsarbetslösheten påverkats av regeringens sänkning av arbetsgivaravgiften?
Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..
ATTRAKTIVT BOENDE I HOFORS KOMMUN : Förslag och förbättringar till hyresrätter inom Hoforshus AB
The little steel industrial community Hofors is situated in Gästrikland on the border to Dalarna and its population is decreasing every year. The biggest housing operator is in a place where they must tear down a lot of buildings because they do not have enough tenants. But what do people really want in an apartment and in the surroundings? What is needed to make it attractive? That is something that this study will discuss and in the end it will lead to a proposal of an area that is suitable for a new housing and a few proposals to make the existing apartments more attractive..

Implied Dividends and Equity Returns
This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.
Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar
To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.
Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus
To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.
Lönediskriminering av invandrare: en empirisk undersökning av invandrares samt invandrarkvinnors förhållanden på den svenska arbetsmarknaden 2005.
I denna uppsats undersöker vi huruvida invandrare diskrimineras på den svenska arbetsmarknaden. Vi undersöker även om förhållandet skiljer sig när vi endast tittar på gruppen kvinnor, och gör en jämförelse mellan svenskfödda kvinnor och invandrarkvinnor. Vi använder oss av två modeller för att estimera löneskillnader, dummyvariabel modellen och Blinder-Oaxaca modellen. Våra resultat ger tydliga indikationer på lönediskriminering gentemot invandrare, kvinnor och en ännu tydligare lönediskriminering gentemot invandrarkvinnor. Vi anser att invandrarkvinnor drabbas av en så kallad dubbel diskriminering, där den övriga populationen i genomsnitt ges 28,4% högre lön än invandrarkvinnor..
OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
Mätningar och betydande faktorer gällande företags kundrelationer: en fallstudie inom Stadium AB
Strong relationships are something that is really important for companies to succeed with, in purpose to increase and protect their market shares. After major research on the subject, it has been found that variables like exchange of relationship, trust, control mutability, satisfaction and commitment are important in the establishment of measuring a relationship. The purpose with this thesis was to: increase the knowledge on how companies measure, and then consequently evaluate, their relationships. To answer the purpose of the study we chose to do a case study at Stadium AB, which is a retailing concern with a high level of customer contact on a daily basis. The conclusion is that trust most likely is the key variable in measuring relationships.
