Utveckling av reglersystem till quadrokopter

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.

Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

Feminist? Nej, inte jag. Kvinnors förhållanden på könssegregerade gymnasieutbildningar.

This paper is about these power strutures seen from the daily round of four girls which study nurse´s training in upper secondary school and four girls which study construction´s training in upper secondary school..

Var går gränsen? : Om sexuella trakasserier i arbetslivet

The purpose of this study is to investigate how the legal protection against sexual harassment at work functions, and where to draw the line. The study is limited to focus on the sexual harassment directed at women from men, because it usually occurs that way even though only a few report the incidents. The results are discussed from a gender perspective on how the distribution of power is between men and women as a way to explain sexual harassment.Sexual harassment is currently protected by the discrimination law and the EU principle of equal treatment for men and women. For a behavior to be considered as sexual harassment it has to be unwanted by the receiving party and the person practicing the harassments must be aware that the behavior is perceived as offensive. The behavior shall be of a sexual nature and contribute to a disadvantage for the victim in the form of a violation of that persons integrity.It is the victim that determines whether the behavior is perceived as sexual harassment or not, what one person believes is a friendly behavior may be perceived as offensive by another.

Feodalismen som fenomen : den säregna makten i det tidiga feodala samhället

The French historian Marc Bloch is considered to be one of the masters of medieval history, particularly his creation Feudal Society has been an essential piece of work for everyone who desires a deeper understanding of the general feudal society. Bloch gives his readers a vivid and living picture of a society so far beyond our present that it is sometimes hard to keep in mind that this society is part of our legacy. At the same time Bloch endows his readers with the special historical outlook he and his successors has developed, the history of the mentalities. By reaching further back in time, to the Roman and Germanic cultures and the manorial system, he proves his point that the feudal society was build on the legacy of older structures and institutions.In the coming study I will disentangle the early feudal structure of power as Bloch has described it in his Feudal Society. The essence of this power structure is to find in the very characteristic tie between two men, the vassalage.

Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..
