Radioräckviddsberäkningar för flygande plattformar

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Samhällets kropp

The foundation for this thesis lies in whether or not, and how, the body representation in printed commercials, specific products directed to the body (shampoo, body lotion etc.), has changed during the last fifty years. Four years have been chosen because of the changes in society that we believe might have had an impact. The commercials that have been picked out are the ones that best represent the general view of the body. We have found that the changes when it comes to body presentation has followed the social development to a certain degree, but it is difficult to say how much the society has had an affect on the body ideal in advertising. Representations of the male body is something that has escalated since the early 70?s, fifteen years earlier few commercials was made with male models, and the few there were, never showed more than the face.

De klassiska sekulariseringsteoriernas arv : En kvalitativ, komparativ litteraturstudie om Weber och Durkheims sekulariseringsteorier och deras giltighet idag.

The secularization theses has over the last decade been a central issue within the sociology of religion. The two classic theses has been criticized for being one-sided and only focus on the change from traditional to modern society. The intention of this study is to evaluate this critique and to discuss what is defendable in the early secularization thesis in our contemporary world.This essay?s primary purpose is to compare the secularization theses Weber?s The Protestant Ethic and the Spirit of Capitalism and Durkheim?s The Elementary Forms of Religious Life. I use two analytical models, posing three levels and three categories of secularization, in order to make the comparison explicit.

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

Vad säger statistik om arbetslöshet? : En analys av den offentliga debattenom arbetslösheten i Sverige inför valet 2005

This essay examines the public debate concerning the unemployment of Sweden just before the general election 2005. Its main purpose is to analyse what lies behind the huge differences in statistics, as presented by the two leading factions in the debate. It concludes that these differences are foremost a problem of semantics, and that although the two factions have statistical proof of their claims, it is their use of terminology that is in fact their main weapon in the debate.The key word here is the swedish word for employment ? sysselsättning ? which the two facitons use in entirely different ways, creating a lot of possabilities for interpretation. This has caused a type of debate which is actually about the reinterpretation this word, and those who are to be included in the statistics as being ?sysselsatt?, therefore, it is semantics that affects the number of unemployed people in the statistics..

Vaccination mot Humant Papillomvirus - vem bör vaccineras?

Background: Infection with Human Papillomavirus, HPV, is one of the world's most common sexual transmitted infections. The virus causes genital warts (condyloma) but certain virus types can cause cancer. The most common cancer type caused by the virus is cancer of the cervix. Nowadays there is a screening program for women between 23 and 60 years of age where Pap smears of the cervix is taken to discover abnormalities at an early stage. Cervical cancer is very common all over the world and this screening program saves many lives, but not in the less developed countries since the screening program is too expensive.

Metod för analys av elförbrukning i hushåll

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

Media och Sverigedemokraterna : Kandidatuppsats i statsvetenskap 15hp, Institutionen för samhällsvetenskaper

This study focuses on nationalism in Central and Eastern Europe. Anchored in theories that this region historically has been characterized by a nationalism that is based on the ethnic group rather than on liberal or civic concepts, it is the purpose of this study to explore whether these theories still apply in recent times when the region has been liberalized, for example manifested in the entry to the European Union. The research question has been tested through analysis of the constitutions of a number of Central and Eastern European countries in order to investigate what type of nationalism that the states have codified in their basic political documents. The results show that some of the states give expression to the historical ethnic nationalism in their constitutions, which indicates that the theories still are relevant..

Energieffektivisering av flerbostadshus i miljonprogrammet

This thesis has been written with our society?s current energy-situation in mind.Although it only deals with one particular block of buildings, the solutions and suggestions presented herein are quite applicable on other objects of the same type.This thesis is intended to be used as a guideline for energy-preserving projects in general, with an eye to buildings erected during the Swedish ?million-programme? in the sixties and seventies.The paper starts with the acquiring of all necessary blueprints and technical specifications. It then moves on to a thorough description of the buildings in question, and their heating- and ventilation-systems.Followed by this the reader is guided through the successive stages of energy-perseverance measures that are available, and possible. Reasoning around the economic factors concerning all measures is also held.The paper ends with conclusion, and a discussion concerning the delicate issue of the higher return-temperatures possibly reaching the district-heating plant..

Att konstruera nya normer för humanitär intervention : Ansvaret att skydda och interventionen i Libyen

The reason I am writing this essay is due to my curiosity on how children are interested in and how their understanding in geometry is at preschool years.My interest lies in children and arithmetic and especially geometry, which is something I belive that children deal with a great deal in their everyday routines, both in school and at home.What do children do when they work with geometry, and are they aware of what they do? To figure this out, I have taken my findings from three different interviews that I have done atmy preschool with a group of children that have been preselected.I am also curious about whether there is a difference in different types of schools. In this essay I have compared the preschool I work with a Montessori school and a third type of schoolwhere the children spends most of their day´s outdoors called ?Ur och Skur?In my results I can not see any major differences in these three preschools work with mathematics. The childrens knowledge is at a similar level and the work with geometry hasbeen implemented in a similar way..

The results show that students reflect on form and performance as well as content, but they place more emphasis on form and performance than content. Students are positive about peer review and its importance for their progress.

Hur företagskulturen påverkar designers arbetssätt : En fallstudie på ett IT-företag

Through a case study at an IT company we have attempted to ascertain how a company's organizational culture affects its designers' way of working. By examining what ?type? of designers the employees are and how this is reflected in their work, we hope to have correctly determined what their organizational culture looks like and thereby have achieved a plausible result in our study.Aside from two interviews with the company's CEO, we also performed eight observations at the company, where we tried to blend in with the employees, to better determine their way of working together.We have found that the designers' trust in their own instincts has led them to rarely act on feedback from clients ? they only pick out the proposals which have a ?mainstream? potential. We have also discovered that their design approach is something they don't feel inclined to discuss amongst themselves. As it is often ?indescribable?, they go with their intuition and unspoken design conventions..
