This report describes the manufacture and control of a flying platform. The report describes the basic and fundamental theories required to get the platform flying. It touches on subjects such as A/D-conversion. PWM-control and PID-control. The sensors used in the platform are a gyro and an accelerometer.

On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.

Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target. The research questions are focused on the translation of information through the organization?s levels and if the management control system makes it possible to run the organization according to both of the two main conflicting objectives.Purpose and Delimitations: To describe, analyze and evaluate how management control can be used in an organization, which is not profit maximizing and has both non-financial and financial objectives. The essay does not try to describe or draw generalized conclusions regarding general perspectives on Systembolaget?s assignment and objectives.Method: A qualitative and evaluative case study based on interviews with five employees at different levels in Systembolaget has been carried through.

BACKGROUND: The isolation facility is an important ward in veterinary hospitals. This is where infectious patients are treated in order to reduce the risk for cross-contamination between the infectious patients and other patients and humans in the hospital. But it can only function in a safe manner as long as adequate precautions for infection control are adhered to. This has shown to be a problem in many isolation facilities in veterinary hospitals in Sweden. AIM: The aim of this paper was to examine which factors that can affect the quality of the infection control in the isolation facility. The aim is also to stress the importance of adequate infection control practices. METHOD: Two interviews were conducted with staff from two veterinary hospitals.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Detta examensarbete syftade till att ta fram ett underlag för en regional åtgärdsplan avseende dibenso-p-dioxiner och dibensofuraner, gemensamt benämnda som PCDD/F eller dioxiner, i Gävleborgs län. Länet har historiskt varit ett av de mest utsatta områdena i Sverige beträffande dessa föroreningar och höga koncentrationer i bland annat strömming har medfört att denna inte får saluföras i övriga EU. I arbetet har resultaten från den rådande forskningen på området studerats för att få kunskap om nuvarande källor och möjliga förklaringar till de fortsatt förhöjda koncentrationerna av dioxiner. Därefter har data från tidigare undersökningar av dioxinkoncentrationer i Gävleborgs län samlats in, sammanställts och använts för att studera hur koncentrationerna varierar geografiskt inom länet. Principalkomponentanalys (PCA) av specifika dioxinkongeners koncentrationer har sedan använts för att försöka identifiera verksamhetstyper som potentiellt kan ha bidragit till föroreningarna på olika platser - en analys som dock är behäftad med stora osäkerheter. De insamlade provresultaten har även använts för att genom massbalansmodellering undersöka återhämtningen i två känt förorenade fjärdar i länet; Norrsundet och Gårdsfjärden.

This thesis studies private equity firms' implementation of management control systems in their portfolio companies and whether the systems are affected by cross-national differences. A comparative case study examines five different private equity firms to derive if there are any differences between the private equity firms' management control systems in the United States, Europe and China. The empirical observations are categorized according to the framework developed by Merchant (1985) and further developed by Merchant and Van der Stede (2003). Theory on the effect of multinationality on management control systems, also developed by Merchant and Van der Stede (2003), are used to explain possible findings. The applied theory includes the cultural dimensions developed by Hofstede (1984) and Hofstede and Bond (1988).

I Jönköping har problemet med översvämningar, erosion och materialtransport varit ett stort problem i Strömsbergsbäcken i Jönköpings kommun. Detta har tillviss del orsakats av ett ökat dagvattenutsläpp i bäcken, vilket skapar kraftigaflödestoppar då den ursprungliga fåran inte är ?dimensionerad? för den ökadevattenmängden. Syftet med arbetet är att effektivisera ekologisk dagvattenhantering i stadsmiljö med högt dagvattenutsläpp. Målet med arbetet är i sin tur att framställa underlag för hur ekologisk dagvattenhantering i stadsmiljö kan genomföras och att rapporten skall kunna ge värdefull kunskap till liknande sammanhang.

Rakkuri sjösystem är den största recipienten för vatten påverkat av gruvdrift ifrån LKABsjärnmalmsgruva i Kiruna och är även recipient för de numera nedlagda sulfid-koppar gruvornaPahtohavare och Viscaria. I den här underökningen har det funnits tillgång till dateradesedimentkärnor ifrån de största sjöarna i Rakkurissytemet, som används tillsammans med nyaanalyser av sedimentet från den tidigare daterade referenssjön Suolujávri. Metallanalyserna frånde daterade sedimentkärnorna har använts statistiskt för att undersöka påverkan från gruvdriftenpå recipientsjöarna.Metallkoncentrationerna i sedimentet följer den naturliga anrikningen av järn- ochmanganhydroxider i ytsedimentet vilken i sin tur sammanfaller djupmässigt med det sedimentsom avsattes kring 1950 då påverkan från gruvdriften till recipienten startade. Sammanfallandetav gränsen mellan förindustriellt- och opåverkat sediment tillsammans med gränsen för densuboxiska zonen i sedimentet komplicerar användandet av sedimentet som arkiv förrecipientens föroreningshistoria. Den här studien kan ändå påvisa att recipientsjön Mette-Rakkurijärvi är påverkad av metaller ifrån gruvdrift.

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

I denna studie undersöktes om känsligheten för stress varierar mellan olika ångestsyndrom. Respondenterna utgjordes av 36 män och 47 kvinnor, samtliga medlemmar i Svenska ångestsyndromsällskapet, som fick besvara 15 bakgrundsfrågor samt PANAS, SE-formuläret och Locus of Control. Några skillnader i stresskänslighet kunde inte påvisas. Dock uppvisade kvinnor högre grad av extern Locus of Control än män, medan män hade fler sömnproblem än kvinnor. Bortfallet i undersökningen är betydande eftersom del av respondentgruppen föll bort.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

This report describes the construction and development of a control box, which is a tool for testing and verifying a certain model of Rapid?s built in staplers (model A6102). Basically the function of the control box is to interpret any errors that may occur in the stapler and to make it possible to test fire the stapler.The control box should be able to communicate with the stapler using a specialized communication protocol. The different data such as errors, firmware etc. from the stapler is presented in plain language on a display.

This thesis examine if social voluntary organisations are independent or if they are being regulated by the public sector. We ask how free the organisations are since they get so much support and funding from the municipality. This is examined by looking at the homogenisation pressure, which means that organisations are being exposed by a pressure to become more similar. The control that the municipality has over the organisations is another aspect in this paper. The study focuses on the relation between the municipality of Linköping and three social voluntary organisations and their characteristics.

This master thesis is made of two parts. The first part concerns the method and results ofdesigning a motion control system for a piece of research-equipment called BIRGIT. Theequipment is made to be used for research on eyemovements. In the second part, a computermodel of a part of the balance organ in the inner-ear is developed. The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.
