Optimerade material för optiska komponenter i koncentrerande solfångare
The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.
Jämställdhetsarbete på en akademisk institution, från ord till handling
The essay discusses how to look at a equality plan of a academic department experiences the, gender equality in general and how power is portrayed from a gender perspective in the academic department. Through the use of qualitative interviews and a short survey the results have shown that few of the staff members have knowledge about the equality plan and few are familiar with its contents. Furthermore results show that the academic department is run hierarchyilly and that both vertical and horizontal gender segregation exists.The climate at the academic department is characterized by the will to work with gender equality but so far there have only been few exercised or planned efforts to do so. The gap between theory and practise is wide, the will to be seen as an equal academic department concerning equality of men and women seems important. The conscious or unconscious strategy of covering up the real gender equality seems to be done by focusing on the numerical equality..

När det omöjliga blir möjligt, Visuella Effekter
Abstrakt
Detta kandidatarbete handlar om visuella effekter inom film och dess utveckling
genom åren. Visuella effekter har öppnat en ny värld för filmskapandet då man
kan skapa i princip vad som helst vilket gör att det omöjliga helt plötsligt
blir möjligt, på filmduken. Kandidatarbetets syfte är att titta på utvecklingen
av visuella effekter och hur man kan använda de kunskaper i en mindre
filmproduktion. Vår problemformulerings frågeställning är ?Hur har utvecklingen
inom visuella effekter sett ut och hur kan man implementera dessa kunskaper i
en mindre filmproduktion??.
I undersökningen analyserar vi hur man skapat scener i olika hollywoodfilmer
som vi tagit inspiration av i vår produktion.
Hur värderar människor utemiljön och dess funktioner? : två fallstudier - Tarapoto, Peru, och Uppsala, Sverige
This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people.
I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala.
The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate.

Processinriktat och resultatinriktat motivationsklimat på svenska och spanska högstadieskolor
Studien processinriktat och resultatinriktat motivationsklimat på svenska och spanska högstadieskolor undersöker skillnader och likheter inom processinriktat och resultatinriktat klimat. I denna studie undersöks det hur dessa två klimat ser ut på svenska och spanska skolor och detta ur svenska och spanska idrottslärares perspektiv. I studien används Nicholls (1989) teori om de två motivationsklimaten. Empirin är inhämtad via semistrukturerade intervjuer med idrottslärare på tre svenska och tre spanska högstadieskolor. Detta i kombination med Nicholls (1989) teori och andra modeller, ligger till grund för den senare gjorda analysen.
Fossilfria godstransporter : En undersökning av alternativ till diesel som drivmedel för lastbilar
Our modern society is in many ways built with and dependent on fossil fuels, which are used for energy production as well as for transporting humans and goods. Without the oil, many of the things we take for granted would not be possible. During the last century, the use of oil has increased steadily and will probably keep increasing as the world population and the economic well-being for many people increase. Since the oil is a finite resource, we will have to find other fuels that can replace it if we want to keep the same rate of development in the future as the availability of petrol fuels will decrease with rising prices as a result. Furthermore, fossil fuels have the disadvantage that they produce harmful emissions when combusted and thus affect the climate and air quality locally and globally.

Att lära tillsammans genom musik - En studie av hur rytmikpedagoger skapar en god miljö för lärande
This study is about how eurhythmic teachers create a comfortable and educational environment in their classrooms. In other words how they create a healthy working environment. Four teachers were chosen for the study, one of them male. I?ve used qualitative interviews because I believe it's the best method to collect information that illustrates what a teacher's working situation looks like and what he/she does to realize their own ideas.

Att bara vara barn - En studie i hur fysisk bestraffning av barn är kopplat till det juridiska klimatet för unga i USA
United States is one of the two countries in the world that have not ratified the convention on the rights of the child, and one of the few countries that sentences children less than 18 years to life in prison without parole. Besides this, corporal punishment is legal in all the states of USA. This essay is aimed at researching how these three factors affect one another in the American context and what consequences may come out of it. By the use of reports from NGO's and UN treaties together with various theories about the subject in question, I have looked into the juridical climate for today's young Americans.The conclusion of the essay shows that there is a tendency in the United States to control violence with violence, from a local level and further to a state level. As long as this attitude proceeds, the situation for children at risk for being sentenced to life sentence will not improve..
Värdering av kvävet i organiska gödselmedel :
Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers.
This project contributes to this knowledge by investigating whether relatively simple and
repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.
Automatisk mätning och detektering av röjande signaler
This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.
