Sweden is considered to have one of the world's highest animal welfare standards in agriculture. Despite this, there are shortcomings in animal husbandry. One example is overcrowding, which is a way to increase stock size without making costly investments in the buildings. It can be carried out systematically to increase profitability or due to, for example uneven calving during the year. The European Commission criticizes the fact that stocking density is not controlled under Swedish welfare inspections.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Föreliggande studies syfte var att undersöka validitet och intern konsistens för den svenska översättningen av Impaired control scale (ICS), en självskattningsskala som mäter grad av kontroll av alkoholkonsumtion. ICS består av subskalorna; Attempt control (AC), Failed control (FC) samt Predicted control (PC). Svar på ICS sammanställdes från respondenter (n = 203) som behandlats för alkoholproblem vid mottagningar i Västra Götaland. Faktoranalysen visade en bakomliggande faktor för AC, och två faktorer för FC respektive PC. Den interna konsistensen var god.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

The purpose of this thesis is to examine how the Management Control System is affected by a change in the owner structure from family owned to not-family owned. The study also tries to identify explaining factors behind the possible effects to the Management Control System. The study is based on a comprehensive case study on the company Alcro-Beckers which, in year 2001, was acquired from the owner Lindéngruppen fully owned by Ulf G Lindén. The acquirer was the non-family owned company Kemira OY, a Finnish stock listed group. The empirical foundation mainly comes from interviews conducted with people who were/are directly connected to the company, either as employees or as representatives for the owner.

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

This Bachelor Thesis is entitled "WTO-spelarena för utvecklingsländer? En studie om avgörande faktorer för utvecklingsländers förmåga att implementera sina regimpreferenser". Through our empirical results in conjunction with realist theories, this Bachelor thesis attempts to answer the questions: (1) How does the decline in American power, the nature of existing institutional structure and Third World unity, influence the ability of developing countries to secure its preferred regimes? (2) What function do informal meetings in the WTO have? (3) How does access to informal meetings influence the ability of developing countries to secure its preferred regimes? The paper makes use of case studies from the Ministerial meetings in the Doha development round.The conclusion is that access to these meetings is an important variable to explain the extent to which the Third World can be able to secure its preferred regimes. The degree to which developing countries can secure their preferred regimes is therefore a function of four variables: the nature of existing institutional structures; Third World unity, the attitude and power of the United States and foremost access to informal meetings..

The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.

En majoritet bland ledare i olika organisationer har en bakgrund som storasyskon eller ensambarn (Hudson, 1990). Denna studie genomfördes för att få svar på om personer med ledaransvar skiljer sig åt gällande syskonplats och locus of control jämfört med de personer som inte har ledaransvar. Ledare och medarbetare på en statlig myndighet svarade på en enkät gällande plats i syskonskara, erfarenhet av ledarskap och locus of control. Resultatet visade att sistfödda i detta urval hade en högre grad av intern locus of control än förstfödda vilket kan tyda på en annan typ av sistfödd på denna myndighet. Urvalet var dock bristfälligt (N = 48) och slutsats kunde inte dras utan att riskera ett felaktigt resultat..

The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.

Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.

We have performed a case study on Acne Jeans, a creative Swedish fashion company, which initiated a cooperation with the Swedish venture capital firm Öresund. The aim of our paper was to examine what motivates a venture capital firm to transform the management control system of a creative company, into a more formal system of control. Main results: Öresund did not have an excessive impact on the management control system of Acne Jeans, due to three main reasons. First of all, Acne Jeans had a satisfactory management control system prior to the cooperation. Furthermore, the relationship between the two parties was characterized by mutual trust.
