Problem: Ekonomer i IT-projekt är ett väldigt outforskat område. Frågan är om ekonomens kompetens utnyttjas och dras nytta av i projekten. Vi vill se vad ekonomen kan ha för roll i IT-projekt och om de kan tillföra något för att förbättra projekten. Syfte: Syftet med uppsatsen är att föreslå roller och arbetsuppgifter som kan passa en ekonom i IT-projekt. Metod: För att kunna nå vårt syfte har vi använt oss av kvalitativ metod. Undersökningen har genomförts genom semistrukturerade intervjuer med en professor i programvaruteknik, företag och PT-studenter som arbetat med ekonomstudenter i IT-projekt under studietiden.

Syftet med den här uppsatsen är att beskriva och analysera hur Controllerfunktionen är fördelad inom en organisation, samt att diskutera orsakerna till detta. En kvalitativ tolkningsmetod har använts där delvis ostrukturerade intervjuer har varit största datainsamlingsmetoden. Uppsatsen har en induktiv ansats. Tre teoretiska perspektiv presenteras i uppsatsen. Först en teoretisk genomgång om vad Controllerfunktionen är, därefter en genomgång av Gummessons modell för ansvarsfördelning och sist Byrne & Pierce modell för Controllerns roll.

The purpose of this Masters thesis is to investigate how actors involved in a municipal's adult education view students access to information- and library resources. The adult education in the municipal is on contract which means that there are several different actors involved in the realization of the adult education. The raised questions in this study deals with; libraries role within adult education, students needs for becoming information literate and where responsibilities for students access to libraries lies. We used a qualitative method which includes interviews with two principles, a Controller, three pedagogues and a librarian. The empirical data is analysed against taxonomies and categories which originates from the theories of David Loertscher and Christine Bruce.

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-Controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & Controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

Ecolean Development AB are developing and manufacturing filling machines for pasteurized liquid food products. Because of lack of any appropriate supplier of box closer which seals boxes with small flaps, they have decided to start a project to develop a prototype of a box closer. Due to long experience from industrial automation I have been given a chance to develop control system for a box closer. Degree thesis involves electric design in ELPROCAD ic PRO and programming of PLC (programmable logic Controller) and HMI (Human Machine Interface). The report describes degree project from the project plan phase via the development phase to the conclusions.

The report analyses if some common problems can be avoided by using modern technology. As a reference system ?Fartygsrapporteringssystemet? is used. It is an n-tier web application built with modern technology at time, 2003-2004. The aim is to examine whether ASP.Net MVC, Windows Communication Foundation, Workflow Foundation and SQL Server 2005 Service Broker can be used to create an n-tier web application which also communicate with other systems and facilitate automated testing.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

Scania är en ledande tillverkare av tunga lastbilar, bussar och industri- och marinmotorer. Inom organisationen finns ett ökande behov av att automatisera och underlätta analysfasen vid klimatsystemprovning. Idag utnyttjas en mängd mjukvaror för att analysera diverse data, men ingen är optimalt anpassad för arbetsuppgifterna inom analys av klimatdata. Uppdraget går därför ut på att utveckla en mjukvara som ska effektivisera arbetet i analysfasen.Det har använts en mängd metoder under arbetes gång. Det har bland annat använts intervjuer vid insamling av kravspecifikationen.

Vi studerar Controllers dagliga arbete inom FoU-enheten på ett stort svenskt företag. Därtill jämförs det dagliga arbetet i praktiken med Controllerns egen samt chefens åsikter om vad tid bör läggas på, samt med den bild av den moderna Controllerrollen som presenteras i litteraturen. För att åstadkomma denna jämförelse har intervjuer utförts med tio Controllers och enkätsvar har erhållits från fem avdelningschefer. De avdelningar som har studerats är de största konstruerande avdelningarna på Scanias FoU enhet lokaliserad i Södertälje. Studien visar att viss tidsbrist förekommer och att Controllers lägger en betydande del av sin arbetstid på rutinartade uppgifter.

The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber.

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot Controller to posess some form of memory as the prey can move out of sensor range.

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microControllers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
