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.

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

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).

In 1513 the Florentine humanists Niccolò Machiavelli composed one of the most famous, but also ambiguously interpret, work in the history of politics, Il Principe. Machiavelli´s book The Prince revealed the true nature of politics in Italy in the beginning of the sixteenth century and gives very straightforward advice on how to act to become a successful and powerful political being. Machiavelli´s creation and insights in the reality of politics have be much discredited and condemned in its lack of moral consideration and violent nature. Still it has been read under the centuries with a fascination and eager to understand the structure of power and how to master it. My purpose with this study is to apply this Machiavellian idea of the capable prince on to the earlier research of the Swedish duke Karl, later on King Karl IX.

Title:Balanced scorecard in the public sector - the balancing of conflicting objectives.Level:Final assignment for Bachelor of Science in Business Administration.Authors:Erika Sundström and Lisette Lundstedt.Tutor:Stig Sörling and Tomas Källquist.Date:2014-05-20.Purpose:The purpose of our study, from a management perspective, is to increase understanding of how the public sector can develop and use the balanced scorecard to balance conflicting objectives.Method:Hermeneutic approach, Literature review, Qualitative case study.Result and conclusion:Under certain conditions, the balanced scorecard can help to deal with conflicting objectives in a public organization. Stakeholders and objectives are important factors for a balanced control. This is due to the fact that many different stakeholders often leads to the creation of conflicting objectives. Numerous and unclear objectives lead to both conflict and uncertainty. The organization?s structure and culture are other factors that also influence.

På senare tid har skolungdomar börjat uppleva sig allt mer stressade. Det kan handla om exempelvis stress inför skolan och den kommande framtiden. Denna studie undersökte elever på högskoleförberedande program upplevda stress, stressen inför framtiden samt eventuell betydelse av Locus of Control och kön. Respondenterna utgjordes av 42 poj-kar och 51 flickor, samtliga gick på samma gymnasieskola i årskurs tre. De fick besvara tre bakgrundsfrågor, en inom stressforskning väl använd stressenkät (PSS), en fråga gällande stress inför framtiden, samt Locus Of Control.

Anställdas produktivitet har överraskande visat sig öka under tidigare nedläggningar. Detta uppmärksammade fenomen benämns nedläggningseffekten och förklaras bland annat av anställdas ökade autonomi och utrymme för innovativa förmågor under nedläggningsperioden. Relationer mellan ledare och underanställda är enligt LMX-teorin av olika kvalitét vilket kan förklara anställdas engagemang, ett engagemang som även kan förklaras av anställdas individuella differenser. Syftet med studien är att undersöka ledarskapets och personlighetsvariabeln work locus of control betydelse för anställdas målengagemang under en nedläggningsperiod. En enkätundersökning för 275 medarbetare utfördes 2006 på ett tillverkningsföretag.

The National Property Board (SFV) has been appointed by the Swedish government to administer all property of cultural value owned by the Swedes collectively. The commission includes maintaining the soul and character of each individual building, to adapt these buildings to present needs and requirements, and furthermore making them available to the public. The return on equity demanded by the government is based on the CAPM used within the real estate industry. The theoretical assumption that organizations are either function-driven or pay-driven will serve as a starting point, after which SFV will be defined as a function-driven organization with a pay-formed management control system. This paper aims to examine how applying a pay-formed management control system will affect a function-driven organization.

ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.

The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

The main focus with this study was to investigate if there was a difference in level ofeducation and self-rated health and if it could be explained by the amount of control,demands and social support at work. Theories used in this essay are education, health,and the job strain-model (control, demands and social support at work). We used analready done study by Folkhälsoinstitutet (2004) to examine these questions. Theanalysed sample consists of respondents 12 166 aged 18-84 years. The decline was39, 2 %.

This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.
