The construction process which is used today while constructing residential buildings has for along time remained unchanged. Unfortunately the development process has gone away frombecoming industrialized and instead most of the work is done at the construction site. In thisrespect this is a worse alternative because the project outcome will be more expensive and theconstruction time will be longer. Skanska?s vision is to have a process which is more like the oneused in small residential buildings which is fully industrialized.The constructing process for residential building involves more parties and therefore it becomesmore complicated.

Uppsatsen beskriver arbetet och undersökning för hur deduplicering i filsystemet ZFS påverkar effektförbrukningen. En större mängd redundant data förekommer i centraliserade lagringssystem som förser virtualiserade servrar med lagringsutrymme. Deduplicering kan för den typen av lagringsmiljö eliminera redundant data och ger en stor besparing av lagringsutrymme. Frågan som undersökningen avsåg att besvara var hur ett lagringssystem påverkas av det extra arbete som det innebär att deduplicera data i realtid.Metoden för att undersöka problemet var att utföra fem experiment med olika typer av scenarion. Varje scenario innebar att filer kopierades till ett lagringssystem med eller utan deduplicering för att senare kunna analysera skillnaden.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

In November 2008 the National Library of Sweden decidedto switch classification system from SAB to Dewey decimalclassification. SAB had then been the main classificationsystem in the whole of the Swedish library field for 87 years.Included into the decision was not just the nationalbibliography but also the research libraries of Sweden. Thisdecision was in alignment with a West European tendency tochange in favor of the internationally well-spreadclassification system Dewey in order to co-operate more inthe cataloguing process. The purpose of this study takenplace in the autumn and winter of 2013 is to examine howlibrarians involved in the transition feel about what differentways the implementation has affected the research libraryorganizations. We also aim to study the librarians? view onthe involvement of the research libraries into the decision ofthe changeover.

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

This work is about silage contaminated with slugs (Arion lusitanicus). The hypothesis was: Do slugs affect the nutritional value and hygiene quality of silage? During the winter season 2007/2008 silages were discarded in big amounts due to the contamination of slugs. Both the Swedish Farmer Association (LRF) and the National Veterinary Institute (SVA) received phone calls from farmers and animal owners about contaminated silage. The Swedish University of Agricultural Sciences (SLU) and SVA decided to initiate this project as a master thesis.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Kärnkraftverk är högteknologiska system med hög komplexitet och utan att hantera den här komplexiteten kan små olyckor få katastrofala följder. Närvaron av komplexitet försämrar förmågan att förstå situationer, minskar kontroll samt ökar risken för incidenter. Stabsarbete inom kärnkraftsdomänen kräver ett agilt beteende för att hantera den höga närvaron av komplexitet. Agilitet är förmågan hos en enhet att framgångsrikt genomföra, hantera och/eller utnyttja förändrade omständigheter. Syftet med arbetet är att utveckla ett mätverktyg för att identifiera indikatorer på agilt beteende i stabsverksamhet inom kärnkraftsdomänen.

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

Purpose: My purpose of this study was to examine the factors that motivate Swedes to travel to Egypt and Thailand. To answer the question, I have used two questions.What are the factors that motivate Swedes to travel to Egypt and Thailand?What is the motive for Swedes choose to travel to destinations such as Egypt and Thailand?Method: The method I am using  is the qualitative method. The qualitative method has been processed through interviews of Swedish travelers, the Swedish travel agencies as well as Egypt and Thailand tourist agencies specializing in trips to Egypt and Thailand via phone and e-mail.Theory: The theory I am using are motivators and push-pull factors in achieving an understanding of the factors that influence choice for Swedes to travel to destinations such as Egypt and Thailand.Empiricism: The goal was to get a much more qualitative data from the response from the Swedish travel agencies, Egypt and Thailand tourist agency and Swedish travelers who have traveled to both of these destinations.Result: What I have come up with in my study is that the factors that motivate Swedish travelers to travel to Egypt and Thailand, is the warm climate, sun and sea, culture, variety, the cheap price situation and that there are activities for different age groups. This has led to the heat in both Egypt and Thailand has attracted Swedish travelers to travel to both destinations.

The park at Djäkneberget and its surroundings is a beloved area in the city of Västerås. The area is one of the most popular sites for outdoor life and recreation of all sorts and it attracts different kind of people at different times during the day. The park includes a pond-system where protected species of frog and toad live and breed. These animals have been the objects for many discussions concerning whether to explore the closeby areas or not. The prospected area is situated just next to one of the main ponds and consists of valuable foundationwalls were experts predict that the frogs and toads spend the winter. The municipality has now decided to restore this area to parkland. Because of the areas fascinating history I have chosen to do some research and give a short resume about it. For example are the existing park of Djäkneberget and its founder described together with a short description of the watersystem with the watertower that is situated in the area.

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

En fallstudie tillämpades för att undersöka de inbyggda apparna, Internet Explorer 10, den nya utforskaren File Explorer och reparationsverktyget ?Återställ datorn utan att ta bort filer? i Windows 8. Analysen visade att apparna E-post, Kontakter och Meddelanden sparade större delar av användarens Facebook-profil lokalt på datorns hårddisk. När bildfiler öppnades upp med appen Foton sparades miniatyrbilder av originalet på hårddisken. När videofiler spelades upp med appen Video sparades filnamnet i filer.
