The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

Construction of Identity and Charismatic Leaders deals with fundamentalism and Islamism within the United States, emphasising on similarities between fundamentalists and Islamists. The term "fundamentalist" is here referring to Christian extremists, while "Islamist" refers to the Muslim counterpart. The purpose of the essay is to make North American fundamentalism and Islamism comprehendible on a larger scale.In order to show similarities between these groups when it comes to values, structure and commitment to their tasks, it is important to understand the nature of the religious devotion.Analyzing the similarities of the two groups enables construction of general criteria for how anthropology of religious extremists can be outlined..

Purpose: In order to curb the prevalence of undeclared work and to improve competi-tion within the building and construction business, reversed charge audit will from July 1, 2007 onwards be applied within the building sector. The new rules entail a consider-able amount of delimiting problems as regards both businesses and services.The aim of this essay is to study the rules as well as direct the light upon various consequen-tial delimiting problems. Furthermore, we will investigate what the effects are on the busi-nesses, as well as their view regarding this. Apart from this, we will also investigate who will benefit and who will be disfavourably affected, respectively, by the new lawMethod: The investigation has been conducted with a combination of qualitative and quantitative methods. Firstly, an opinion poll was carried out, directed towards Swedish construction companies, and this was then deepened using three interviews.Result & Conclusions: The essay demonstrates that the new rules have entailed more work to a varying degree for the companies.

The aim with this report is to investigate what influence the way playgrounds are used throw the case study in Vänersborg, and also to find methods for municipalities to collect information about how playgrounds are used. The methods were observations, interviews with parents and children, a questionary with questions about what playgrounds they used, how often and why they used them and what the children used to do there. There was also a demographic investigation and documentary research. The most popular playground, Skräcklan, gets visitors from all parts of the municipality. It is located in a park with a view over the lake Vänern, there is a parking place and a café and it has furthermore a large area and many play equipments. Many of the families make shorter trips and picnics to this place. In exception of this playground, the families almost always go to the playground in their neighborhood and their part of the town.

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

Den huvudsakliga tillverkningen på svetsavdelningen består av fram- och bakramstillverkning.

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.
