The following article consists of two parts; one part is about house construction and the other is a specialization about radon. The house construction part describes how to project a house from start. It contains the conformation of the house, the installations needed, calculations considering the strength of the construction, energy calculation and what materials were chosen. Calculations considering the costs of building and operate the house has been carried out. The result showed that the house would cost approximately two million Swedish kroner to build and thirteen thousand kronor a year to operate.

This report describes the scientific work of designing and manufacturing an intelligent controller module prototype for automobile trailer connections. The functions of the module are both to drive the lamps and detect failures. The module also contains functions to handle other functions of the trailer. To learn about controller modules the group does extensive feasibility study.The group receives three already existing modules, the functions of the three modules are studied and tested in the lab, this is done too get a overview of the construction. The method used I called reversed engineering, a way of constructing by analyzing constructions already done.When the modules are analyzed, the functions of the prototype are tested and designed without copying the analyzed modules.

What can make us identify ourselves with places? Why do we feel stronger for certain environments? Is it possible to change the identity and how can we do it? What exactly is building identity on a site, what elements it is safest to hang on to when the wind of change is blowing? In this paper, I?m going to discuss the subject identity in different ways and from different angles. Important questions I have had, has been how to analyze a site and what is the importance of identity and the possibility of changing it?The first part of the paper aims to provide an introduction to the concept of identity. I'm giving a short explanation of what identity is and how places relate to identity.

This essay is about publishing on the Internet and aims to understand the differences between publishing information on the webpage Wikipedia (Swedish version) in contrast to other information pages on the Internet, for example blog, discussion pages, homepages etcetera. The study is based upon an article which described that 90% of the information publishers at Wikipedia belongs to a small elite of white, western, well educated men between the age of thirty to thirtythree. This study examines why people who does not belong to this heteronormativity publish information in other Internet places but not at Wikipedia.Wikipedia is an open source site, where anyone can publish and are even encouraged to do so and is often described as an utopian dream of the digital democracy, so why don´t people express themselves on Wikipedia? The method is based on two discussion groups, which are compared and analyzed. The study is based upon theoretical competence within feminist theory and conceptions such as intersectionality, heteronormativity and digital divide as well as theories about digital devices and social order.

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

This report deals with prefabricated bathrooms and the advantage, during the production process, they have compared to ordinary produced bathrooms.The work is done together with the building company JM. The common task is to investigate if the manufactures, in spite of standardized design can meet the concept of JM, i.e. high flexibility and adjustment towards the customer. In JM they are doubtful to the method, as they did not yet worked with prefabricated modules and think that the choises for the costumer will be limited.There will be a short resume of the progress of the bathrooms and its importance as sanitary and wellbeing.The recent problems with damage caused by damp in bathrooms. Have resultade in regulations.

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.

This Degree project summarizes how it is to work in the CAD program Revit Architecture. This was done because AQ Arkitekter in Eskilstuna is interested in how Revit works. Especially compared to AutoCad which is the software they are using today. Will their work become more efficient with the new software?The starting point was to find out how it is to work with Revit when you only used AutoCAD Architecture before.

One of the most crucial entries in the financial statements is revenue. Despite the importanceof revenue a lot of mistakes are made concerning this entry because of the extensive room forjudgements. Especially in the construction companies where a lot of differences exist due tothe fact that different standards are used for similar business transactions.The research concerning IFRIC 15 and the new upcoming standard for revenue recognition isnot very extensive. Studies including both IFRIC 15 and the new standard are even morelimited. Therefore this study aims to compare the effects of IFRIC 15 and the new upcomingstandard for revenue recognition, Revenue from Contracts with Customers, in three Swedishconstruction companies.

During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
