Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab 

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

Innovativ utmatningsteknik : Mediumstor bulkförvaringslösning

This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.

Konstruktion av serviceutrustning till tunnelborrningsmaskin

The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.

Användning av högpresterande betong i husbyggnader : Materialförsök och modellering

Idag är intresset för högpresterande betong (HPB) växande runt om världen då fördelarna är många, eftersom slankare, tätare, starkare och lättare konstruktioner kan tillverkas. Detta examensarbete handlar om materialförsök och modellering för en typ av HPB som ska användas i husbyggnation. Arbetet inleddes med materialförsök i färskt tillstånd, där god gjutbarhet och konsistens eftersträvades. Utgångspunkten var från ett grundrecept med två olika ballastsorter (slaggballast med flygaska och krossballast från asfaltindustrin med silikastoft), vilka namngavs till pilotförsök 1 och pilotförsök 2. Vidare valdes pilotförsök 1 att provas i hårdnat tillstånd då det visades att det var mer ekonomiskt lönsam eftersom ballasten inte behövde siktas, lägre vct tillhandhölls och att flygaskan som användes i pilotförsök 1 är billigare än silikastoft som användes i pilotförsök 2. Resultaten efter 28 dygn för de materialförsök som utfördes i hårdnat tillstånd var:Tryckhållfasthet; 141,9 MPaDraghållfasthet; 7,0 MPaBöjdraghållfasthet; 10,0 MPaElasticitetsmodul; 46,4 GPaKrympning efter 56 dygn; 0,5 ?Samtliga försök utfördes enligt svenska standarder (SS). Dessutom vidareutvecklas och förbättrades ett redan arkitektoniskt gestaltat Attefallshus ur ett konstruktions- och hållbarhets perspektiv, där fokus låg på transport- och produktionsförutsättningar.

Barnarbete : En lokal studie av barnarbete i Stråssa gruva under början av 1900-talet

AbstractBachelor essay in Pedagogy by Johan Lidén &Kristian Sagfors, 2011."Genus i gymnasieskolan: En oengagerande fråga?".Supervisor: Zeki YalcinGender and gender equality in our school system has throughout the years become a well researched subject, however most of that research has focused on the lower levels of compulsory school. The upper secondary school has not gotten the same attention.We have chosen to explore how social science teachers in upper secondary school treat the subject of gender and gender equality, what strategies they apply in the classroom and how their pupils respond to the subject.We wanted to get access to their classrooms so we could do an ethnographical study to find the answers to how their lessons were planned and executed, if different teachers made different didactic choices depending on the orientation of the class. As our work progressed we ran in to an interesting problem which ultimately made us rethink the purpose of this paper.In our pursuit of respondents we contacted many schools by e-mail and later visited the schools to find participants. This proved difficult as we were met with a wall of silence and lack of interest.

Studie om individers kontrastkänslighet och preferenser för horisontell och vertikal belysningsstyrka

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

Det kulturella tomrummet : En diskursanalys av kulturprojekt bland elever på särskilda ungdomshem

This essay deals with the rationale and aims for doing cultural or aesthetic activities and projects in schools, and gives special focus to a specific group of students, attending schools provided at special residential homes for young people (sa?rskilda ungdomshem). These homes receive young people with psychosocial and substance misuse problems and who show tendencies towards criminal behavior. The essay investigates how working with a cultural project in schools at these residential homes is justified and also elucidates how this specific group of students and their problems are constructed in the documents surrounding the project. The essay will further ponder over possible educational and pedagogical consequences of these constructions.The investigation has its theoretical frame work in curriculum theory.

Abnorm avkastning utifrån Benjamin Grahams värdestrategi : Ett ex ante test för de svenska, amerikanska samt japansk aktiemarknaderna

Theability to beat the market is one of the most discussed topics in finance. Thereare very few investors that manage to accomplish this over longer periods oftime. Most of the financial research claims that this is impossible unless theinvestor increase the risk in the portfolio. However numerous of researchershave shown that it exist anomalies on the stock market which either indicatesthat the Capital Asset Pricing Modell (CAPM) or Fama and French three-factormodel fails to explain stock returns or that the market is not fully efficient.One investor that has claimed that the stock market is not fully efficient andthat it is possible to generate abnormal return is Benjamin Graham. Graham isone of the legends on Wall Street and he has shown that by using few variablesbased on public information, one can manage to beat the market over longer timeperiods.There arejust a few studies that have tested Graham?s criteria?s, however all of themindicates that they work but that the standard deviation might be higher forthe portfolios.

Kungliga bibliotekets fotografiska förvärv : En undersökning av Kungliga bibliotekets förvärv av fotografier under 1958?2008

My master?s thesis is a study of acquisition of photographies during 1958-2008. The questions I proceed from is what patterns lies behind the Royal library's acquisition of photography and how the process of acquisition looks like. The theoretical base which I lean on consists partly of a problematization of the process of cultural heritage and partly of organizational theory. The problematization of the process of cultural heritage is my foundation of this essay.

Ledtidsreducering för färdigställning av bergborrstål vid
Sandvik Materials Technology

Detta examensarbete är utfört på Sandvik Materials Technology (SMT) i Sandviken. SMT har under ett antal år arbetat mot att infria deras två största kunders, Atlas Copco Secoroc och Sandvik Mining and Construction, önskemål om en leveransprecision på 95% och en ledtid på tre dagar för storvolymprodukter av bergborrstål. Idag är leveransprecisionen tillfredsställande medan ledtiden är fem dagar. Examensarbetets syfte är att analysera vad som krävs för att infria Atlas Copco Secoroc's och Sandvik Mining and Constructions önskemål om tre dagars ledtid för storvolymprodukter. Ledtidsreduceringen ska åstadkommas med nuvarande skiftform och utan att leveransprecisionen påverkas i negativ riktning.

"Utanförskapets reservarmé": talet om Rosengård i svensk dags- och kvällstidningspress

The aim with this study has been to examine and to analyze the discourse of Rosengård in Swedish media. With the concept of discourse is meant here specific ways to speak about and to understand the world, or a part of it. In order to reach increased understanding regarding media presentations and constructions of Rosengård, I have done a study about how Rosengård has been presented in the Swedish daily and evening press during the violent acts that took place in Rosengård in the spring and summer of 2008, when youths regarding to media put cars and containers on fire, and also threw stones at fire engines and other emergency service vehicles when these had to turn out to put out the fires. The collected data, containing newspaper articles, has been analyzed on the basis of the critical discourse analysis, CDA, which is a mould of a textanalytical method. This study applies a social constructivist perspective.

Inventering av tillgängligheten i Bilbergska huset.

Akademiska Hus owns and manages the university facilities in most university towns in Sweden. Bilbergska house in Örebro was built in 2008 by Akademiska Hus, and designed by White Architects. Today's buildings must meet accessibility requirements determined by Swedish Board of Housing, and it is the developer who must ensure that they are fulfilled. Swedish Board of Housing requirements are often vaguely written and interpretation space is large.This report aims to investigate how much of the requirements which are set towards the University and landlord Akademiska Hus are being achieved. This is done by studying the requirements that are set.

Korsvirkestraditionen i V?stra G?talands l?n Utbredning, konstruktion, karakt?r och kontext

This bachelor?s thesis examines the tradition of half-timbered buildings in V?stra G?taland County as there is a current lack of research on this building category in this region. The lack of knowledge may lead to the loss of potential cultural heritage values if these buildings do not receive attention. Therefore, the study aims to provide a more comprehensive understanding of its role within the region. The goal is to expand and nuance the existing research on the Swedish building tradition, particularly in V?stra G?taland County and the general Swedish half-timbered tradition.
