The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

The data consist of 1042 Swedish small enterprisesand 30 different financial ratios between the years 2005?2007. The result shows thatbankrupt firms three years before bankruptcy have a disadvantaged capital structurewith poor solvency and high debt.

Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

This thesis analyses how romanies look upon schooling and how they reflect upon the possibility of getting an education. Many inquiries relating to romanies have been published in Sweden but very few are based on fieldwork among romanies. The aim of this thesis is therefore to through fieldwork focus on how romanies themselves look upon their educational situation.The main questions for this study are: How is the image of romanies as a problem constructed in school? How are romanies separated from other students? How is the interplay between romanies and school representatives formed? How do romanies look upon the possibility of getting an education and does their perception differ from the usual official apprehension?An important conclusion concerns how social workers and teachers continuously categorize romanies as different. The group is constantly differentiated from other ethnic groups and is often the target of integration projects.

This paper examines what affects the demand for five Swedish ethical funds between the years 1997-2007. The purpose of this study is to examine if there is a relation between fund value and other values than just financial. This study examines if the number of conflicts in the world and the media?s coverage of the climate change debate could have an impact on the demand for ethical fund. A multiple linear regression shows that we don?t have a significant result from the examined variables except for household wealth.

The Center for Genomics and Bioinformatics (CGB) is an academic department at Karolinska Institute. Generally stated, the CGB department is committed to the generation and management of genetic information by approaches aiming at elucidating the connection between genes, protein and function.WiGID is a genome information database that is available through WAP (Wireless Application Protocol).Our version of WiGID is based on WML, PHP and PostgreSQL as a database server.One of the changes on the old WiGID application was the creation of a relational database with seven tables and one view, instead of the file that represented the database on the old version. We also changed the script language from python to PHP.The search engine ability has been extended with three new search alternatives for a user to choose from. Each choice leads to other, sometimes multiple choices.A GUI has been created for the administrator, to be able to insert information into the database.The structure of the search engine is primarily for narrowing down the search result on the phone display, thereby making the search efficient..

Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

The education sector can be seen as a cornerstone of today's society, an organization that is under constant change and evolve as society. The compulsory school system is of significant role in society that places high demands on its management. The following study investigates the requirements for documentation in primary school organization and operations, and how these requirements are perceived and affect the school's organization and activities of the study carried out at different levels of the organization so as to get an overall picture of its impact. In order to analyze and create understanding of the results, the study applies the theory of New Public Management and various reforms that can be linked to the increased documentation requirements and its influence in the public administration. Study results show that there is a mixed picture of the documentation impact on the school system. Shown are both positive and negative effects of the documentation requirements.

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

We have examined how the dependence, identity and social bonds affect customer loyalty and attachment to a training centre. The method used is a survey on SATS Karlstad city where 128 respondents were asked, out of which 118 surveys were used in the final analysis. The data was analyzed using ANCOVA and multiple regressions.The result showed significant relationships on attachment between identity and dependence. Social bonds had no significant effect on the attachment a member have towards training centre. Customer loyalty was measured by how long the individual has been a member and his or her training frequency.
