Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik
In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

Energieffektivisering av arbetsbodar på byggarbetsplatser
Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.
Det energisnåla isoleringsmaterialet
This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.
En r?rspis: och hur den ?r uppbyggd

The theory chapter is based on different strategies that companies have to or can apply to get ahead, stay or survive in a hypercompetition.
EUropa och den konstruerade identiteten - En analys av den hegemoniska diskursen
In this thesis the construction of identity within the EU is discussed. A thesis problem in three dimensions is used to explain the purpose of the construction, its realization and the consequences of such identity. These aspects show the complexity of the problems related to identity construction on a structural level.By using a post-modern and a social constructivist theoretical approach identity is presented as socially constructed by discourse. The theory of discourse makes it possible to analyze the development of an identity forming discourse within the EU and its status today.With an approach inspired by critical theory, we use discourse analysis as a methodological tool to illustrate the ideas that govern discourse, and in what way it is related to the social reality.The analysis states that the purpose of identity constructing is the striving for legitimacy. Without identification, the legitimacy is threatened.
Effektivisering av EPC projekt : Fallstudie Johnson Controls

Husproduktion, kritiska skeden i produktion
As a newly graduated student in construction you rarely have as much knowledge as you wish you had. It is a complicated line of business that requires knowledge and understanding of both technical solutions and interaction between actors. It is impossible to be fully learned and with that much unknown it can be hard to know where to start. This report is one step in the right direction. It contains a planning that contains construction and installations for a one level house in Kiruna with its different choices motivated.
Ämnet Idrott och hälsa som grund för ett längre arbetsliv
The purpose of this study is to examine how well the teaching of physical education meets the needs of a future life in the building and construction industry. In order to answer the survey's purpose, we have carried interviews with teachers for the subject Physical education and health as well as with teachers for the Building- and construction program in order to through their experience gain understanding of common health problems in the profession, but also to gain a deeper understanding of the importance of the subject Physical education and health for this profession. We have reported and described previous research and then analyzed it during our processing of collected data material. The result of the interviews showed that the teachers as far as possible are trying to adjust the lessons to suit this practical program. They also indicate several aspects to consider in order to further customize the education for students in the Building- and construction program.
Kvalitetssäkring:En analys av egenkontroll
A degree thesis about quality control and assurance in construction. Made in cooperation with Wästbygg. An analysis was made of the self-monitoring control that is conducted during the construction. The data was collected from interviews from personnel employed by Wäsbygg as either work-leader, project-manager or quality- and environmental-coordinator. During the study there was also a review of the literature in the subject.
Tesauruskonstruktion i ämnet landskapsplanering
This research paper is a thesaurus construction for the interdisciplinary subject of landscape planning. The personnel doing the indexing of documents at the Swedish University of Agricultural Sciences had earlier expressed a need for such a work within the fields of Landscape Architecture and Landscape Engineering. However our objective was not to create a complete thesaurus, but instead a basic construction which the personnel at the Agricultural University could expand upon. The actual construction is based upon ISO 2788-1986, Documentation Ð Guidelines for the establishment and development of monolingual thesauri, and Aitchison, Gilchrist and BawdenÕs Thesaurus Construction (1997). The line of enquiry taken has dealt with the problems relating to the collection, selection and control of indexing terms.

Purpose: The purpose of this thesis is to survey: which strategic variables are of great importance in today?s Swedish construction industry with focus on the four main actors, JM, NCC, PEAB and Skanska.
"Jaha, det gick ju bra den här gången också" : En kvalitativ undersökning av seniorers förhållande till e-handel
In this paper we have examined why seniors do not use e-business to the same extent as other age groups. Seniors belong to the age group that, according to statistics from Statistics Sweden (SCB) in 2011, utilizes e-business the least in relation to the number who use the internet. To understand how seniors reason and perceive the possibility to shop on the internet, we have conducted four interviews with people from 65 years and older. We have let the respondents answer questions regarding utility aspects, e-business interfaces, general shopping habits, risks, and whether or not they usually shop online. We also found out how seniors reason when they sell products and services.
