Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

The complex sound of someone walking in snow aren't easy to create in a studio. The best way to get the sound is to go out on a surface with real snow and record the footsteps there, but it is a complex procedure to get the right sound on the snow because snow sounds different in various temperature and various kinds of snow. It is important to find the right kind of snow to get the right sound on the foot steps. In a studio, the foley artist can create the sound of footsteps in snow by walking on different kind of material, like potato flour, coarse salt or corn flakes, the question is how realistic this materials sounds and what temperature on the snow they sound like. The results shows that the real snow (warm and cold snow) sounds most realistic and the potato flour sounds like warm and wet snow, the corn flakes some think sounds like cold snowwhile others think that it doesn't sound like snow at all and the coarse salt sounds like snow when it is around -10°C in the air, they all sounds similar in realism compared to each other.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

This report is about planning a demolition. The purpose of this report is that it should become a base for a demolition of house J at the Academic hospital in Uppsala, and also to make general help for planning a demolition. This report also contains a part about how a change in the work environment affects general people. The work started with studies of literature and design of the general part of the report and then continued with a practical study of house J. From the experience of the first two parts of the report a general help for planning a demolition was shaped.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.

In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.

Education systems face a number of challenges regarding social justice, diversity, difference, and inclusion and membership for all students in the groups that schools create. This invokes questions of how well these challenges are met in curricula and teaching materials. Through discourse analysis of eight Swedish geographical textbooks, this essay aims to seek out the perspectives surrounding difference within the subject of geography. It concludes that the idea of fixed homogenous cultures as meaningfull in differentiating among people dominates throughout the latter half of the 20th century and during the last decade. In addition, it concludes that the discourse surrounding diversity in Swedish geographical teaching materials mainly has a binary liberal view of plurality focused around tolerance.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

Miljöcertifieringssystemet för byggnader, LEED (Leadership in Energy & Environmental Design) lanserades 1998 i USA av USGBC (United States Green Building Council). USGBC är en icke vinstdrivande organisation, vars mål är att bidra till utökat hållbart byggande. Skanskas första byggnad som certifierades enligt LEED färdigställdes 2001 i den amerikanska delstaten North Carolina. I slutet av februari 2009 offentliggjordes det att Skanska skall införa systemet i sin Nordiska organisation. Undersökningen som genomförts handlar om ett av LEED New Constructions sex delområden, Materials & Resources. Materialhanteringen för ett byggprojekt som Skanska uppfört har analyserats för att avgöra huruvida det skulle kunna erhålla poäng vid en certifiering enligt LEED.

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..
