System Andersson AB is a company located in Jönköping that works with developing computer systems for the mechanical engineering industry. As of today, when this report is written, the company is working on the development of a new Manufacturing Planning and Control (MPC) system. This new system aims to create not only a user friendly interface but also a modern, stylish interface. To achieve this, the company has decided to work with a, for them, new application framework; Windows Presentation Foundation (WPF).System Andersson is well known for developing systems for different kinds of touch screens, this project is no exception. For this new user interface the company wishes to implement different types of Drag&Drop functionality.

In several cases, systems that have been developed have been very time consuming and cost a lot of money, but they still do not fulfil the users requirements and requests. To make new systems better, you have to find a way to communicate that allows the developers to understand the needs of the user. The aim for our thesis is to highlight the importance of communication in system development. To investigate this we have choosen to do a study of the real-estate system. The work methods that have been used include mock-ups and informal conversations with the user, who is employed by the Church of Sweden in Ronneby.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Problem: Hur såg kundrelationerna ut innan det nya IT-systemet infördes och hur ser kundrelationerna ut med ett nytt IT-system? Kundrelationer som tidigare har hanterats via telefon eller på plats har ersatts av dagens lösning med ett IT-system som går att komma åt via Internet och ger mer möj-lighet till självbetjäning. Detta leder till frågorna: Vilka för-ändringar har IT-systemet medfört? Hur har interaktionen påverkats?Syfte: Att beskriva och förklara hur införandet av ett nytt IT-system påverkat interaktionen (relation) mellan ?kund? och leverantör vid en tidpunkt 5 år efter systemets införande. Med kund avses golfspelare och med leverantör avses golfklubb.Teori & Metod: Teoriavsnittet består av två delar.

The aim of the study was to study how a today journal system is applied in homecare. The aim was also to examine if a portable journal system could make any effectiveness on the nurse's work and secure the quality of care. The study is a part of a project called Grensebroen which connects public health care, economic industry and university to a network beyond the borders. The primary goal of this cooperation was to develop technological means of assistance which could simplify nursing on daily basis. An empirical study on homecare was made in a district were long distance travels were common for the nurses in duty.

Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.

The aim of the study has been to explore certain aspects of implementation perspectives and to analyse the introduction of an environmental management system called ecoBUDGET in the Municipality of Växjö. A framework has been developed through thorough studying of earlier research in the field of policy implementation in public administrations. The framework is made up of the steering relationship between politicians and public administrators, decision making and implementation and the ability, want and understanding of how and why decisions should/could be implemented. By using this framework in combination with interviews held with individuals that host valuable knowledge and experience of the system these questions were to be answered:-What factors in the implementation process of ecoBUDGET can be seen to have facilitated alternativly hindred the integration of the environmental management system within the municipalitys administration and companies?- In what direction has the integration of a sustainable devleopment thinking for the environment thru ecoBUDGET evolved within the organisation?The result came to be that sustainable development and the strive for this is more and more amalgamated in to the everyday work within the municipal organisation and that the environmental management system is likely to have played a part in this..

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.

Husqvarna AB uppmärksammade att det kommer införas nya miljöregler i Kalifornien gällande diffusionsutsläpp. De åkgräsklippare som går under namnet Rider och tillverkas av Husqvarna idag uppfyller ej dessa krav. Dagens bränsletank är tillverkad i plastmaterialet HDPE och avdunstande bränsleångor klättrar lätt igenom tankväggen ut i atmosfären vilket ej är tillåtet enligt de nya reglerna. Vi blev tillfrågade om vi kunde lösa problematiken och ta fram ett system som kontrollerar de avdunstade bränsleångorna och se till att detta system uppfyller de krav som ställs i Kalifornien. Som blivande ingenjörer tyckte vi att detta var ett passande examensarbete med många olika områden involverade som materialkunskap, tillverkningsprocesser, produktutveckling samt inblick i ett större företags arbete. Vi har med detta examensarbete tagit fram ett system som minskar det miljövådliga diffusionsutsläppet med cirka 90 %.

This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

De flesta företag använder sig av något slags system för att kontrollera arbetsflödet. Dessa system används av alla på företaget och därmed är det viktigt att undersöka, hur medarbetarna upplever detta system. Med en explorativ utgångspunkt gjordes en enkätstudie på ett företag i Västsverige. Resultatet visade att deltagarna, förutom några få procent i stort sett hade liknande positiva upplevelser. Ingen skillnad fanns heller mellan grupperingarna ung/gammal eller antal år de arbetat på företaget.

Precis som titeln avslöjar handlar rapporten om att utveckla ett system som kananvändas vid utvärdering av övningsmoment. Idag saknas ett liknande system somvara ett stöd för hemvärnets instruktörer vid utvärderingar som har till syfte att ökaförståelsen hos övande personal. Systemet består av en mobilapplikation och enwebbapplikation. Mobilapplikationen loggar hur en soldat har framryckt under ettövningsmoment och sedan sammanställs data från en eller flera mobilapplikationer ien webbapplikation där data visas på en interaktiv karta. Kartan ger möjlighet attstega sig igenom händelseförloppet.

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
