Jämförelse av olika presentationsteknikers inverkan på precisionsbedömningar gällande avstånd i virtuella och verkliga miljöer
Denna rapport behandlar skillnader i bland annat visuell information (som olika djupledtrådar) vilka kan ha betydelse för den visuella upplevelsen och inverkan på till exempel precisionsbedömningar gällande avstånd i både virtuella och verkliga miljöer.Rapporten lyfter fram tre olika presentationstekniker som presenterar visuell information i olika utsträckning. Två av presentationsteknikerna, Desktop och CUBE, presenterar två virtuella miljöer. Den tredje presentationstekniken, Verklig, presenterar en verklig miljö. De tre presentationsteknikerna ställs mot varandra i en undersökning gällande eventuella skillnader i precisionsbedömningar (avståndsbedömningar mellan och på olika objekt). Resultatet visar att det föreligger signifikanta skillnader vad gäller precisionsbedömningar mellan den virtuella presentationstekniken Desktop och Verklig samt mellan den virtuella presentationstekniken CUBE och Verklig.

10-åring spårlöst borta : En studie om hur försvunna barn konstrueras i svensk press
The purpose of our study was to examine how missing children are portrayed in media. We wanted to see if there are any recurring story patterns and characters in the texts. We also wanted to examine how the relationship between children and adults are framed and which comprehensive view of children is mediated in journalistic texts.Our questions were: how do Swedish newspapers write about missing children? Which narrative pattern are there in the texts? How are children and adults represented in the texts? What relationship between children and adults are made visible in the texts? What a comprehensive approach to children is constructed in the texts?For this study, we used the media discourse, theories of representation, stereotypes and characters. And theories of narrative, dramatic turns and opposites.We chose to make three case studies in which children suddenly disappeared, the case of Bobby Äikiä, the case of Engla Höglund and the case of Sebastian Hedman.
Konstruktion av steghållare till brandbilar
High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .
Prefabricerade Passivhus
European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.

Researches on different methods of cutting, types of automatization and possible designs were made. To implement the project a design and construction from the base where chosen.
Shape from Silhouette Scanner
The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.
Konsten att synas och skapa långsiktiga relationer med kunder : En studie om Sociala Medier och Sökmarknadsföring
The use of internet is growing rapidly and many people choose to spend a lot of their time in the virtual world. This is the reason why we believe that it is important for companies to consider using internet as a tool to reach their customers. Today many companies, especially within the fashion industry, have acknowledged this and use internet marketing to reach existing and potential customers. Social media and search marketing are two helpful tools that can be used in order to make a company visible on the web, given that they know how to use them effectively. The purpose of this study is to examine how companies within the fashion industry can use social media and search marketing to reach their customers and what kind of attitude they have towards using these tools.
En kartl?ggning av inv?ndiga f?nsterluckors utbredning och konstruktion
Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in
modern buildings. In modern contemporary construction, large glass panels are often the ideal because
of increased light inflow and for architectural purposes. However, this can generate several negative
effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that
window shutters could have accommodated historically.
This thesis identifies a lack of knowledge about interior window shutters in the Swedish building
stock.
Ämnestransport med grundvatten i hydrogeologiska typmiljöer
Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.
"Månntro hon är homo?" : Om lesbiska kvinnors identitetsformering och livsvillkor 1950-1965
The construction of an identity among lesbian women during 1950-?1965 is in focus in this master ?s thesis. My starting point is that identity, such as lesbian or any other identity, is formed in relation to other people and groups, as well as society. This thesis will also examine how lesbian women met and formed bonds with like-minded, and whether these aspects changed, during the defined time period. The empirics is made up by letters written by women to Riksfo?rbundet fo?r sexuellt likabera?ttigande (a Swedish organisation for lesbian and gays) as well as an interview with two lesbian women who were born in 1938 and 1940.
Off-Shore Blackboxing & Global Software Development : En studie av utmaningar och möjligheter med distribuerad systemförvaltning
Global Software Development (GSD) is based on a geographical distance where teams are spread throughout the world. The related research have for a long time addressed the challenges presented by geographical distances. GSD is basically a necessity for many businesses to use in order to reduce development costs, reduce production time and to maintain high quality. The study aims to investigate the relationship between the reality of a specific maintenance project. Thus, our research question: How do distributed maintenance teams experience temporal, geographical and socio-cultural distances? To achieve the purpose of the study, we chose to perform a case study of a global consulting company which recently started a new system maintenance project.
BYGGBRANSCHENS MILJÖUTMANING ENLIGT PLATSCHEFER, ARBETSLEDARE OCH YRKESARBETARE: EN INTERVJUSTUDIE GJORD PÅ BYGG- OCH FASTIGHETSUTVECKLINGSBOLAGET NCC CONSTRUCTION SVERIGE AB
Byggsektorn står för en stor del av det totala avfallet i Sverige och står därmed inför stora miljöutmaningar. Däribland finns NCC Construction Sverige (nedan kallat NCC), Sveriges tredje största byggföretag med cirka 10 000 anställda. På varje bygg- eller anläggningsarbetsplats på NCC upprättas en miljöplan där olika krav omhändertas: lagkrav, lokala föreskrifter, beställarkrav samt interna krav.Studien genomfördes i samband med författarens praktik på NCC i Göteborg, avdelning Anläggning, med syftet att synliggöra yrkesarbetare, arbetsledare och platschefers syn på miljöarbetet på företaget - idag och historiskt. Totalt genomfördes 8 anonyma personintervjuer; två platschefer, två arbetsledare och fyra yrkesarbetare intervjuades under hösten 2014.Studien visade att ekonomiska incitament är viktiga för att miljöarbetet ska kännas berättigat för dem som utför det - framför allt för skeptikerna. Pappersbördan är hög och vissa anser att miljöarbetet enbart är en pappersprodukt utan egentlig mening.
Köldbryggor och energiförluster. En studie om energiförluster genom balkonginfästningar och deras betydelse för byggnadens totala energibehov
In this report the balconies? abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinforcement bar that holds the balcony runs through this heel.
