This master thesis is a result of the work carried out for Research Electronics at Siljansnäs. The company develops customized electronical systems. Because of the rapidly increasing interest in colour displays there has been a desire within the company to represent information from sensors and electrical systems in a more advanced way.Due to the mentioned reason above we were given the assignment to solve how a colour display using the STN technique works. The technique is used by small displays, the size of QVGA. Our ambition of this diploma work is to develop a fully functionally test prototype to evaluate the LCD (Liquid Crystal Display) and the LCD controller.

Controllerrollen har sitt ursprung i USA där den verkade i de amerikanska järnvägsbolagen under 1800-talet . Termen kom sedan till Sverige runt 1970-talet då intresset för en controller ökade i Europa. Behovet av controllerfunktionen har ökat bland annat beroende på en ökad decentralisering, som medför ett behov av exempelvis information kring företagets ekonomi till flera nivåer.I och med att omvärlden förändras så måste även företagen förändras. För att kunna behålla sin konkurrenskraft har ekonomistyrningen samt controllerrollen hamnat mer i fokus. Controllerns arbetsuppgifter har gått från att enbart vara inriktad mot bokföring till att ha en mer verksam roll i ledningsgruppen. När det anses otydligt vad en controller egentligen ska arbeta med blir det svårare för företagen att själva förstår motivet till varför de tillsätter en controller. Detta är viktigt för att de ska få den controllerroll de söker.

In this master thesis a robot arm belonging to an automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain scheduling is a type of controller where the parameters of the controller are changed during operation, for example depending on the working point. First a nonlinear mathematical model of the system was made.

In today?s changing environment, creation of projects by organizations has become more common. The problem is, though, that the knowledge of the subject is still limited which causes many projects to fail. This has made it extra important to have a good project manager whocanlead the project in the right direction. While doing this both the project method and the project manager?s motivation are contributing sources.

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

  iiiAbstract?We are living in a time of project. Everything becomes project. All development, all efficient,all changes are running as project?.

More than half of the implemented IT-projects go over budget, deadline or simply fail. The processes in an IT-project requires technical competence to be present among the project participants to ensure the achievement of business goals and to make organisations competitive. The success of an IT-project largely depends on the project manager which makes it interesting to further investigate what impact the project manager?s technical competence has on the project. Previous research shows differing opinions whether technical competence is considered important for the project manager to be successful or not.

This project concentrates on musicians who work in a professional music studio.The task of this project was to design a new headphone system called Foldback system.The advantage of this system is that all involved in a music project could influence their ownlistening during the project. With a couple of adjustments should each and everyone get theirown individual listening from their headphone station.This report shows different methods, theories and results that came along in development ofFoldback system. The project has resulted in a finished product that will be in use atStudiomega..

Denna studie behandlar controllern och dess roll. Då controllerrollen upplevs som väldigt diffus är syftet att förtydliga vad en controller är genom att använda begreppen bönräknare och företagspartner. Den teoretiska referensramen tar upp teorier från centrala författare inom området, bland annat Lindvall, Mattsson, Frenckner och Samuelson. Studien är en kvalitativ studie och utfördes på Saab AB i Arboga. Totalt åtta stycken djupintervjuer genomfördes med både controllers och icke-controllers för att på detta sätt kunna få en djupare förståelse för controllerrollen.

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

There are several Project Management Softwares onthe market today. These tools are powerful andextensive to the degree they become too timeconsumingand complex and therefore often defeatits original purpose. This is the case especiallywhen the project manager is inexperienced and/orthe scope of the project is moderate.The purpose of this thesis arose from this context,there seems to be a gap between a home-made MSExcel spread sheet and the advanced softwaresavailable. The thesis and the product has beendeveloped in alliance with Faveo ProjectManagement with the shared goal to create a toolwhich is easy to use but still covers the essentialareas of project management theory. The tool willbe used internally by Faveo-employees as well asexternally together with Faveo?s clients in aneducational purpose.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
