This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

The purpose of this examination work was to make a general description about drying and storage of grain, and a case study with a comparison between brought and home-made feed. The case study was made on the farm Solhem in Hörby, a farm that produces 3870 pigs for slaughter a year. In this project three alternatives have been compared, 1st alternative: own produced grain approx. 400 ton + wet grain 415 ton purchased during fall, 2nd alternative: own produced grain approx. 400 ton + dry grain 415 ton purchased during winter, 3rd alternative: bought feed 815 ton purchased continuously during the year. Considering the price information provided to me the 1st alternative gave the cheapest feed..

The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..

The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.

Vid affärssystembyten väljs ibland standardsystem framför egenutvecklade system. En orsak är att egenutvecklade system är dyra och komplicerade att bygga. Flera företag tycker också att det är smidigare att implementera standardsystem då dessa är utformade som en paketlösning där samtliga moduler är integrerade.Ett problem för företag är att välja "rätt" standardsystem. Ett arbetsmål i denna uppsats är att ta reda på i hur stor utsträckning företag använder sig av en metod i anskaffningsprocessen. Huvudfokus är att ta reda på vad företag tycker är viktigast att anpassa - verksamhet eller system? Ett annat delmål är att titta på hur företagskulturen förändras vid ett standardsysteminförande.I undersökningen görs sex företagsintervjuer hos företag som alla har anskaffat standardsystem.

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

I denna uppsats undersöks huruvida HPM (High Power Microwaves) kan användas som enverkansform i framtida luftvärnssystem för att bekämpa kryssningsmissiler. Studien undersökervilket hot kryssningsmissiler kan utgöra, hur de är konstruerade och hur HPM kan påverka dem.Uppsatsen redogör för hur det nya luftvärnskonceptet är uppbyggt och vilka krav på förmågor somställs på framtida luftvärnssystem. Den undersöker även hur ett HPM-system är uppbyggt ochvilken verkan det kan ha på elektriska system i en kryssningsmissil. Vidare diskuteras vilkeneffekt tre olika HPM-system kan ha mot kryssningsmissiler kopplat till de krav som ställs iluftvärnskonceptet.Huvudslutsatsen indikerar att HPM-system kan ha verkan mot kryssningsmissiler. HPM-systemkan nyttjas främst i scenarier där det ställs höga krav på eldhastigheten mot kryssningsmissiler påkorta avstånd.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.

This report is about how to decide which method is the most suitable as floor covering at projectKlammerdamm in the centre of Halmstad. The covering has to be fire resistant and soundproof inorder to protect the wood structure and stop noise from traveling between apartments. There aretwo possibilities either traditional gypsum board or gypsum-based self leveling underlayment.The roads around the construction site are narrow. A regular twenty-five meter long truck has nopossibility to reach the site. The construction site is small and the storage area is limited.

 This study was conducted in autumn 2008 on the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy vehicle industry and has annual sales of approximately 250 MSEK with 165 employees.The rapid growth and unchanged planning is the starting point for this report. It all began in 2005 when the company received an unusually large order. During this period, the first priority was to satisfy customers and all other focus was disregarded. This has primarily resulted in a messy production and long throughput times.

The purpose of this thesis project was to study how different companies are working with LastTime Buy and through that study propose improved ways of working with this for Scania CVAB. The project aimed at studying the work processes from three different perspectives:decision models, quality aspects and liability aspects between companies.To study this, qualitative interviews with one or several representatives from differentcompanies that are affected by or involved in Last Time Buy were used. Representatives wereselected partly from Original Equipment Manufacturers, suppliers, component manufacturersand companies offering third part solutions for Last Time Buy. The companies also reflecteddifferent industries. The interviews aimed to create an understanding for the methods used atthe different companies but also the ways of thinking and the knowledge behind the choice ofthese working methods.The analysis shows that the Original Equipment Manufacturers used very similar decisionmodels for Last Time Buy, but that external factors or the company strategy made them reachdifferent results.

The purpose of this Master?s thesis is to examine how the gender system is described in chick lit. The analysis is based upon seven chick lit novels. The primary theoretical point of departure is Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes.
