The projects goal is to construct and program a robot that is controlled from a computer but also have an obstacle handling function that allows the robot to navigate around the object by itself.The robot is a simple construction and the number of components and functions is kept at a minimum. A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..

The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.

The fragmentation and reduction of deciduous forests in Sweden is threatening many species. Particularity worrying is the loss of broad-leaf trees, since a diversity of species is often associated to them. Today many deciduous trees are situated along the border between forested and open areas, and these small fragments can be important for biodiversity.The aim of this study is to analyze if wildlife management can affect the variation of deciduous trees and bushes in the landscape. In brochures and literature Svenska Jägareförbundet (the Swedish Association for Hunting and Wildlife Management) recommend hunters and landowners to promote deciduous trees ? often broad-leaf trees ? as wildlife management measures, while the Swedish forestry laws can be sensed as unclear regarding the treatment of these trees.Five properties in Södermanland, Sweden, were chosen as study areas and inventoried in respect of trees and bushes in September 2013.

AbstractThis report has been developed in cooperation with Peab Region Bostad Göteborg, mentor at Krook& Tjäder (through Chalmers), and examiner at Chalmers University of Technology. The report is the result of a research of a building project, constructed by Peab. The report is investigating and it means to identify and evaluate qualities in the dwelling and its surroundings. Its purpose is to evaluate how the residents in a chosen housing cooperative enjoy living there. It shall, with help of chosen quality aspects, identify what expectations the residents had before moving in, how they experience the dwelling and its surroundings today, and what hopes they have for the future planning of the area.

This paper, Personal safety when working with weather encapsulation constructions, is focused on weather encapsulation constructions and how the absence of Swedish standards and regulations is affecting the safety for the workers. The usage of weather encapsulation construction is increasing in Sweden therefore the needs for standards and regulations are becoming more and more urgent. The risks involving the rising and the demolition of the weather encapsulation construction and when the construction is transported along its rails are treated in the paper. Since there are no regulations companies have had to solve the safety issues without instructions, the paper regards how the companies have solved this problem without the support of formal institutions..

Today there are many different Cad-applications on the market for engineers. Because of big building projects it has become more and more important to work with the same application or to have access to a neutral file type to be able to transfer files between different ones.This report studies the single objects and how they react when transferring them between ADT and ArchiCAD via the neutral type IFC. We have also been looking at problems during the transfer between and if there are some connections between these problems. Afterwards we created a neutral object model of a small country house to see if the objects appeared different. The result shows no differences.But looking at the problems that appeared during the transmissions they felt small and no logical.Today it is not possible to save in a neutral type without facing small problems.

During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future. I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection. Included in the study are four areas, three of which burned in 2005 and one in 2006.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

Entrepreneurial firms face unique challenges in attracting and acquiring human resources due to difficulties associated with resource constraint and organization legitimacy, often described as liabilities of "smallness" and "newness". The aim of this paper is to examine the "smallness" and "newness" challenges met by small entrepreneurial firms, which strategies they apply to counter these challenges, and if these strategies can be explained by the firm's HR philosophy. Since few studies on Human Resource Management (HRM) in small entrepreneurial firms exist, a framework combining theory from the research fields of HRM, entrepreneurship and small firms has been developed. Employing a qualitative case study design of five small Swedish entrepreneurial firms, our findings demonstrate four "smallness" and "newness" challenges and seven strategies that either counteract or prevent them. Furthermore, results showed that the strategies applied seemed to have no significance with regards to the firm's HR philosophy.

Stockholm has in recent years experienced a strong population increase but despite that fact, the demand for housing has not been followed by enough housing contracts. According to forecasts, growth in population will further be continued upward. With more condominiums than rental units on the market, new apartments are too expensive to live in. This creates unsustainable problems for those in lower classes of society. Creating a housing market in the periphery of Stockholm is not sustainable from a social perspective.

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

In this study we describe the needs of lone parents and how the authorities fulfill these needs. The needs contain both economic and social aspects, such as the access to an employment, childcare and the possibility to social activities. For the lone parents being able to work the childcare provision must improve and be available in a greater extent during non-traditional working hours. It is also required that the housing benefit ceiling is increased so that the parents may work more hours without risking the loss of the housing benefit. The statistic about the housing benefit which we present shows that many of those with a low income are lone parents.

Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.

The purpose of this thesis was to illuminate and create a deeper understanding of how small niche retail businesses within the apparel industry position themselves. We aimed to investi-gate how these small niche retail businesses create their position and how they communicate these positions to their target market. To be able to investigate the positioning-process within these small niche retail businesses a case study was conducted based on interviews with two respondents from two different companies and observations of these businesses physical envi-ronments. The study indicated that the small niche retail businesses mainly make use of emo-tional aspects and their assortment range to create their position. To communicate their posi-tion to their target market they mainly use their in-store personal selling and their assortment range..

The aim of our study has been to investigate what kind of space there is to exert influence for adult persons with mild intellectual disabilities who live on group housing. We wanted to investigate what kind of hindrance and possibilities there were to exert influence for people on group housing. Our study has been built on qualitative group discussions with 9 persons with mild intellectual disabilities and 6 care-keepers. We have analysed our discussions on the basis of the theory of empowerment. Our result indicates that there is different kind of factors that affect the possibilities for people with mild intellectual disabilities to increase their influence, and it does not always have to do with the disability how the persons can make their voices heard.
