This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

When different type of programs are developed one wants to make these adjustable to future changes and requirements. It must be done a good design of the program from the beginning to make it possible to continue development of it without having to redo big parts of it to high costs. In the area of object orientation there are design pattern, which can be used to design systems that can be adjusted to new changes in an easier way. I have in this thesis chosen to take a closer look at how to design a program that sends SMS to cell phones through a system of an operator. One requirement on the program is that it has to be possible to change what operator to send though in an easy way.

Today the common people begin to understand the impact of a package. Many choose brand or product with great emphasis on how the outside looks, both in a good and a bad way.The company Gotlands Grafiska gave me the task to create a small basic selection of packages. The target group that the project was based on was craftsmen in the Gotland region. Based on analysis of the market and consumers to develop a range of packages covering a wide range of products sold on the island.During the project a clear theme was the desire to highlight a product and create some sort of exclusivity.

The aim of my study is to look at two specific schools and their work with Internet in the classroom and compare their work to what experts say about how you should educate. The study focuses on how teachers guide the students to be critical to the information they encounter on the internet. What do the experts say? How should the teachers work with Internet in the classroom? What do the teachers say about their work with Internet? What do the teachers say regarding children and the Internet?  To answer these questions I have interviewed two teachers from different schools, which had classes with children 6 to 8 years old. The schools are very different from each other concerning investment on Internet devices in the classroom.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..
