Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Bachelor essay in political science by Andreas Byfeldt, autumn 2007?The practice of deliberative democracy- limitations or enhancements of representative democracy??Supervisor: Erik AmnåThe purpose of this study is to find out what impact the practice of deliberative democracy might have on a representative democracy. What effects deliberative democracy could have in this context are scientifically as well as publically relevant seeing that participation in representative democracies as well as the forms of representation is altering.The essay contains both a theoretical segment and a case study. The information regarding the case is based on the results from a questioner, conversations by and observations from the author. In addition an analysis is performed in the case study.The conclusion of the essay is that there is too little empirical research on the subject of deliberative democracy to make a qualified conclusion about what effects the practice of deliberative democracy could have on a representative democracy.

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

Could patterns change the way we as consumers feel about a product as it ages and wears down? Why do some products increase their value as they are being worn downand others do not? Could the same affection that increases with your favourite jeans or an old, worn down, scratched and beautiful wooden furniture, be applied on otherproducts with different ability?s and history?The goal was to explore patterns and beautiful aging in products to increase the consumers desire to keep the well used product a little bit longer. Not to prolong the products ?lifetime? from brand new till it?s no longer inhabit their main function, but at that precise momentwhen you as a consumer decides to through it away in favour for a new, updated version. To buy ?new and fresh?.Patterns with different expressions, colouring and size, were explored that increase the value of a product which in this project contained handles and varies of surfaces on casseroles, frying pans, whisks, cutlery etc.

Inventory management is a key part of a company?s logistics function and is of great importance to companies as it is a substantial cost. It is of high importance for a company to make sure that the warehouse is efficient as possible. In this thesis two factors that hurt a warehouse?s efficiency are introduced; inventory inaccuracies and lead-time variations.This thesis has been dedicated to analyze how inventory inaccuracies and lead-time variations arise and how to eliminate them.To be able to solve this question we have used a qualitative research method.

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

This report deals with the design of a controller for SmartMedia? flash memory cards, based on a hardware description found in the SmartMedia? Interface Library - SMIL. The design was made on logic gate level, using standard cells in OrCAD Capture. After simulation of the design in PSpice A/D, it was exported as an EDIF netlist, which was used to make a chip layout in L-Edit, a layout tool for making integrated circuits. The layout was made using a method called Standard Place and Route - SPR, where the layout tool places standard cells from a library and connects them according to the EDIF netlist.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

The purpose of this thesis is to determine whether the student councils at two schools really have the power to influence, or if it is a matter of mock democracy. I wanted to determine how the student councils work in reality. I conducted my investigation through personal and qualitative interviews with the board of the student council, a social studies teacher and the principle/school management at both schools. After the interviews I compared an analysed my findings. The results show that the two schools work very differently when it comes to studentdemocracy, and even have very different levels of ambition when it comes to the degree of influence that the student council should have at their respective schools.

The present study aims to examine how teachers write polemical articles. This genre often occurs in national standardized tests in Swedish schools. The study seeks to analyze argumentative structures in the articles. It also categorizes assessment notes written by the teachers in response to each others? articles, by interpreting response texts.    The examination shows that there is uncertainty among the teachers about how to create structures in argumentative text types.

The aim of this essay is to investigate the murals in the church of Arbrå, what they portrait and how they can be linked to medieval typology as described in Biblia Pauperum (BP), the Poor Man?s Bible. The aim is also to find out what the purpose was to paint medieval churches and what the function of the paintings was. Arbrå Church was painted around 1520-1530, and almost all of the motifs from the Old Testament can be directly traced back to BP as can one motif from the New Testament. Together these paintings represent most of the important events which make out the foundation of the Christian Cult.
