Recent studies show that the knowledge in and understanding of science, technology andmathematics of Swedish junior high school and high school students is decreasing. As a resultof this the Swedish government has initialized several studies, research and reforms. One ofthe theories for teaching that today is seen as effective is the socio-cultural perspective and itsdescendants, including scientific inquiry. Using the pedagogy of the socio-cultural perspectivefour assignments regarding the human body was constructed for junior high school studentsattending summer research school in the summer of 2008, hosted by AstraZeneca. Theassignments follow a structure (goal of assignment, preparations, experiment and follow-up)inspired by the concept of NTA ? Naturvetenskap och Teknik för Alla (Science andTechnology for everyone).

This assignment focuses on the concept of ?school trips? and Gotland. Pedagogically, the school trip was initially focussed on practical and national aspects, the education to be made visible and the idea was to present Sweden, its nature and its industries. The Gotland administration chose to focus on the unique and cultural history, and it was unusual that visits were undertaken to factories and workshops. This was also the start of the current tourism trend where knowledge of the value of the countryside and the opportunities for tourism is a successful combination, which can be seen today even if the school trips now have different areas to visit.

This thesis is about cover illustrations of DVD movies as examples of visual communication. I have studied the cover illustrations of the three movies Gran Torino, Secret Window and As White As Snow. My research assignment has been to find out how the cover illustrations of DVD movies communicate in relation to the story. I have also been looking for what makes a cover illustration interesting and if the interest in itself is individually considered or if there are certain general rules regardless of the observer.To reach a conclusion I have been studying components in advertising pictures, visual communication and how the commercial producers use advertising to communicate with the observer. Semiotics, advertising and comparisons between the cover illustrations have been my method for analyze.I have come to the conclusion that cover illustrations are meticulously produced, and that every single part of them is important for the observers? over all impression and interpretation of the cover illustration.

The world has changed its understanding of environmental issues dramatically and more people are showing awareness of social and environmental problems. Various stakeholders have increasingly begun to show an interest in how companies are taking responsibility for their actions. This has led to an improved activity amongst organizations to make their production consequences positive. They work with Corporate and Social Responsibility (CSR). In order to communicate their responsibilities, many companies work with CSR and ethical guidelines.

Abstract This master thesis is a result of the work thas was done for my entry in the international architectural competition Urban spaces and urban life in Ørestad South, that was announced by Ørestadselskabet on the 31st of October 2006. The project work lasted from early November until the deadline on 14th of February. In addition to the proposal that was handed in, the master thesis consists of a number of reflections about the work that was done and design work in general. The proposal is an answer to a not that evident task. One would expect that the assigment was clearly defined in the brief of the competition like this. And so it seems to do but to define the real assignment and join your own aims to it from such an extensive brief can be quite time consuming. Why do architects participate and what is an architectural competition? How does the brief affect the choices and statements made by the entrants? What is a square? What is the strategy that leads to a convincing concept? The role and use of a concept in the design process.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible. When investigating the different principle of purifying water, a research of different products and their manufactories was done. These different products were compared and the principle of filtration was the most applicable, as most of the products were designed for far larger applications. As the process water contains quite large amount of particles, it is necessary to perform the filtration in different steps. The process water purifier is therefore composed of a module of coarse filtration and one of micro filtration. In the module of coarse filtration the mainly amount of fibres and particles are eliminated. They are kept back in the container unit with the larger fragments and dumped with these when the container is emptied. In the module of micro filtration the filtration is performed in two steps. In the first step particles larger than 50?m are eliminated, in the second step the micro filter is setting the range of purifying, in this case 10?m.

The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
