Målet med detta examensarbete har varit att undersöka kunskapsnivån angående vind i bebyggd miljö hos verksamma inom stadsplanering, arkitekter och inom berörda utbildningar samt tillgängligheten på hjälpmedel och information. Vinden påverkas starkt av landskapets utseende. Skog, hav, stad och kuperad terräng har alla olika vindförutsättningar. Inom urban miljö bestäms vindförhållandena av bebyggelseutformningen och byggnadernas omgivning. Historiskt har vindplanering varit en naturlig del av planerandet, inte minst då det gäller jordbruk. Under årens lopp har människor tagit lärdom av tidigare erfarenheter vilket har lett oss fram till dagens kunskapsläge med en rad olika tumregler och hjälpmedel, varav det senaste består i numeriska datorbaserade analysverktyg så som Computational Fluid Dynamics. En god och komfortabel utemiljö utgår ifrån hur vi människor upplever den.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.

Heart failure is an illness that requires life-long treatment and often affects everyday aspects of a person?s life. Self-care is a significant part of the treatment. Good self-care resources make it possible for people with heart failure to make the lifestyle changes they often need to maintain or improve their level of health. Self-care means having knowledge of and being able to recognize the symptoms and signs of deterioration that can occur with heart failure, so that the person can take appropriate measures ? and it also means knowing when it is time to seek professional help.

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

SAAB Automobile ABis a car manufacturer within General Motors corporate group. SAABAutomobile ABhas a big part of the responsibility for the brake development in the corporategroup. The car industry is facing harder environmental requirements, which influence the brakedevelopment. The focus is to develop brakes with low drag and sustained brake feeling andperformance. Important characters for the brake caliper are high stiffness and low weight, highstiffness results in high performance and low weight is important because it is unsprung mass.This thesis investigates the possibility to improve the performance of the brake caliper for aGMproject.

Horses are made to eat mainly roughage and it is essential for optimal health to offer them an appropriate amount of roughage with good hygienic and nutritional qualities. To produce good hay at the right time and be able to keep the hygienic quality until next summer is a problem. This has the effect that horse owners today choose haylage and silage to a larger extent. Science in this area is scarce, i.e. if the change from hay to silage has any effect on the horse.

The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.

Vid torrgranulering av masugnsslagg med roterande disk hälls den smälta varma slaggen i en stråle på den roterande disken. Slaggen slungas sedan radiellt ut åt sidorna från disken och sönderdelas till partiklar. Torrgranuleringen bidrar både till att en värdefull produkt i form av cement kan framställas, samtidigt som energin från den varma slaggen återvinns. I dagsläget finns dock inte tillräcklig kunskap om hur olika processparametrar påverkar sönderdelningen och storleksfördelningen av partiklarna för att kunna tillämpa processen inom industrin. Syftet med projektet var att skapa en experimentell och en numerisk modell av torrgranuleringsprocessen med roterande disk för att undersöka hur olika processparametrar påverkar sönderdelningen och storleksfördelningen på partiklarna, samt att utveckla en bildanalysmetod för att validera den numeriska modellen mot de experimentella resultaten.En experimentell modell av torrgranuleringsprocessen med roterande disk skapades i laboratorieskal och förenklades genom att vatten användes istället för masugnsslagg.

Changes in the climate and the environment are largely consequences of human influences. Resources are given to teach adults about the environment. However, there are problems in focusing on adults because it is difficult to influence people when they already have created a lifestyle. We have instead chosen to focus on teaching children about changes in the climate and the consequences of this.Many of the toys available on the market today encourage children to consume. Luxury cars and dolls with hundreds of accessories are often made of materials that has have a negative effect on the environment.Another problem we often encountered during the year is the declining interest in technology and science.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

I fo?ljande arbete underso?ks en partikelbaserad simuleringsmetod som kallas Fluid-partikelmetoden, FPM. FPM a?r designad fo?r att simulera komplexa fluiders beteenden pa? mesoskalan, vilken sammanla?nkar kontinuumskalan med den molekyla?ra skalan. Metoden utvecklades av Pep Espan?ol i slutet av 1990-talet och a?r en vidareutveckling och generallisering av Dissipative Particle Dynamics som togs fram av Hoogerbrugge och Koelman under tidigt 1990-tal.
