This abstract describes the bachelor degree thesis in computer technology at Växjö University. The company BSR in Växjö has requested an application that can measure a cars performance, with attributes like acceleration times and engine power estimation. The communication between car and computer is via the USB port on the computer and the OBD-II socket on the car with the network protocol CAN, controller area network. Cars from VAG have been the primary focus group and the application has been tested on a Volkswagen Passat CC from 2009. The system is developed in the programming language C# in the environment Visual Studio with the framework .NET.

The aim of this study was to explore how six men who run a micro-enterprisewith a maximum of 10 employees handle the balance between work and otherlife. Qualitative approach with semi-structured interviews was conducted and thesample consisted of six men with micro-enterprises of varying ages. The themesused in the interviews were boundless work, roles, boundaries strategies anddemand / control - social support. The results showed that micro- entrepreneursdo not experience any major imbalance between work and other life. The studyrevealed that the division of roles in the home of the elderly respondents was ofthe classical gender character that woman took great responsibility in the home.Among the younger respondents the unpaid work at home was equal divided.Social support was perceived highly by all respondents, and they alsoexperienced a high level of control over the requirements of the job.

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

This report deals with the design of a controller for SmartMedia? flash memory cards, based on a hardware description found in the SmartMedia? Interface Library - SMIL. The design was made on logic gate level, using standard cells in OrCAD Capture. After simulation of the design in PSpice A/D, it was exported as an EDIF netlist, which was used to make a chip layout in L-Edit, a layout tool for making integrated circuits. The layout was made using a method called Standard Place and Route - SPR, where the layout tool places standard cells from a library and connects them according to the EDIF netlist.

Sammanfattning  Det finns många definitioner av vad yrket controller innebär, vilket visar att yrkestiteln är svårdefinierad. Syftet med studien är att beskriva controllerns arbetsroll i medelstora tillverkande privata företag och om controllerns roll fokuserar mer mot styrorienterade uppgifter eller mer mot traditionella ekonomiuppgifter. Vi utformade därför följande frågeställning: Är dagens controller i tillverkande företag mer styrorienterad eller mer en traditionell ekonomichef? Vi valde att genomföra en kvalitativ studie eftersom det möjliggör en djupare förståelse och sedan använde vi oss av en deduktiv ansats där vi gick från teori till empiri. I vår teoretiska referensram har vi beskrivit olika egenskaper, färdigheter, roller och arbetssätt som ingår i controllerns yrke.

Bakgrund: Sjukvården beskrivs som oerhört komplex och genom bland annat utveckling av ny och dyr teknik, som i sin tur genererar bättre vård, gör det svårt för sjukhus att hålla sin budget. En controller har en fundamental roll i en organisations ekonomistyrning och ska med hjälp av diverse styrmedel styra och kontrollera så att verksamheten drivs mot ekonomiska mål.Syfte: Syftet med uppsatsen var att beskriva och analysera hur en controller inom sjukvården använder ekonomiska styrmedel för att nå ekonomisk måluppfyllelse samt skapa en förståelse för hur en controller hanterar balansgången mellan ekonomisk måluppfyllelse och vårdkvalité.Metod: Uppsatsen är formad med en kvalitativ forskningsdesign. En flerfallstudie har använts som forskningsstrategi där den empiriska datan är insamlad genom ostrukturerade intervjuer med anställda vid två sjukhus i Småland, länssjukhuset i Kalmar och centrallasarettet i Växjö. Det teoretiska avsnittet är byggt med data som insamlats från litteratur och vetenskapliga artiklar som varit tillgängliga via Linnéuniversitetets bibliotekskatalog.Slutsats: De resultat som framkommer av studien påvisar att en controllerns användning av styrmedel tenderar att fokusera på ekonomisk måluppfyllelse. Genom användning i större utsträckning av de styrmedel som är under utveckling finns möjligheter för controllern att även påverka vårdkvalité..

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..

My questions at issue for this report has it´s beginning in the growing problems of thenegative effects of burning fossile fuels and the rapidly growing energyprices.1. Is it possible to design a micro scale powerplant?2. Is it economically interesting for a potential customer to by such a product?The aim with this report is therefor, with the help of design work and calculations, to answerthese questions and to create a platform for building a fully functional micro scale powerplant.The material used in the report is mostly product catalogs from various industries but alsostudy course littrature about steam engines.The result of the report is that it is fully possible to design a fully functional micro scalepower plant.

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.

Background: Sweden has, since 1983, had a statutory audit for all joint-stock companies. However, according to EG?s fourth corporation directive, member countries can decide on their own if this applies for small joint-stock companies. An investigation was launched in the fall of 2006 to form an opinion on the importance of the audit reporting by law and what an abolishment of this rule would mean for small joint-stock companies. Critics are claiming that the cost of audit for small companies is exceeding the cause in these micro companies.Audit is regulated by Swedish translation (RS) of International Standards on Auditing (ISA) and is to be applied in all companies comprised by the statutory audit.

Micro-power wind energy convertors have recently increased in popularity. The reasons for this are among other things the increasing cost of electric energy and enviromental concern.In this thesis the connection of these micro-power wind energy convertors to the utility network is discussed. Electric standards for the connection of small production units is presented. Finally some calculations and measurements of electric quality are also presented. The utility network used in the calculations is part of Halmstad Energi och Miljö network..

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.
