Genom att föra samman människor med olika bakgrund och utbildning kan åtskilliga idéer skapas, nya metoder utvecklas och mer kreativa och originella designlösningar produceras. Baksidan är, att ju fler olika människor med olika bakgrund som är involverade i ett projekt desto svårare blir det att kommunicera inom gruppen av olika individer och svårare att komma vidare i en design- och utvecklingsprocess. Vi har under våren deltagit som en del i ett större programvaruutvecklingsprojekt och skapat och använt oss av flera olika designartefakter som medel för att främja samarbete, kommunikation och designarbetet av den produkt vi utvecklade. I denna uppsats beskriver vi hur dessa designartefakter har kommit till, förändrats och hur de har påverkat oss och vårt designarbete. Syftet med uppsatsen är att visa på vilket sätt man kan integrera metoder från olika discipliner i ett programvaruutvecklingsprojekt och framförallt hur arbetet med, och kring designartefakter spelar en viktig roll i utvecklingen av en produkt..

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.

This work concerns children with reading- and writing difficulties/dyslexia. My purpose is to investigate the practical experience of teachers as well as their everyday work with these children.My questions are:How do teachers work with children aged 4-9 who have reading- and writing difficulties/dyslexia?Which various teaching aids exist for children who have reading- and writing difficulties/dyslexia?Which subjects are affected by reading- and writing difficulties/dyslexia?To answer the above questions I have used the qualitative method. I have performed interviews and observations. Previous research has shown that reading- and writing difficulties/dyslexia is one of our most common disabilities.

This thesis is a case study which describes the automation of a university library in Sub-Saharan Africa. The aim of the case study is, firstly; to find out which actors and factors have started and influenced the automation and the implementation of ICT at Makerere University Library in Kampala, Uganda. Secondly; it also discusses if the automation has changed the librarys condition. The empirical material consists of fifteen interviews with librarians and students. The empirical material itself has functioned as a base when discerning the analytical themes.

Denna rapport beskriver examensarbetet vi gjort för LBS Science Park AB. Anledningen till att vi gjort just denna applikation var att LBS Science Park såg ett problem i den Internetbaserade hästannonsmarknaden. Det fanns ingen ledande annonssida, utan användare som skulle sälja eller köpa hästar fick använda sig av flera mindre sidor. Vår uppgift blev att undersöka marknaden och att skapa en applikation som samlar annonser från flera hemsidor på vår applikation. Rapporten är indelad i tre huvuddelar, som belyser de juridiska, de tekniska och de innehållsmässiga frågorna.

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.

 Syftet med den här studien är att undersöka vilka yrkes- och studiebakgrunder yrkesverksamma datalärare har och om olika bakgrund leder till skillnad i uppfattningar om deras yrke och utbildning. Dessutom syftar arbetet till att undersöka hur datalärare håller sina ämneskunskaper ajour och om det finns skillnader i fortbildning beroende på utbildning och yrkesbakgrund. För att besvara arbetets frågeställningar används en kartläggande kvantitativ enkätundersökning som besvaras av yrkesverksamma datalärare från hela landet. För att få fram resultaten görs vissa sambandsanalyser och dessutom presenteras deskriptiv statistik. Undersökningen visar att majoriteten av datalärarna saknar lärarbehörighet samt att ungefär hälften tidigare har arbetat utanför skola och har professionella tillämpningar inom sitt ämne.

AbstractThis essay concerns a qualitative case study seeking to understand six boys? reading habits and to investigate why it is that some boys who do not like reading nevertheless display good reading comprehension according to the results achieved for that skill in national tests. The study shows that the boys? perception of reading has a lot to do with the contact they have with books when they are small. Whether or not there are adult role models in the home and whether the early encounter with texts in school is a positive or negative experience is significant for the boys? later attitude to reading.

The aim of this Master?s thesis is to examine in what way library users are depicted on images at two academic libraries; the University College of Borås Library & Learning Resources (BLR) and the Gothenburg University Library (GUB). 62 images, from websites and information brochures, are analyzed and the main questions are: How are users represented on images? What activities are shown? What is the difference between BLR and GUB? How can the consequences of the representations be understood? Little is currently known in the LIS-field about how images work as constructors of the social reality. The theoretical and methodological point of departure of the study is discourse analysis, new institutional theory and picture analysis.

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.

This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments.

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..

Fotorealistiska 3d-bilder används idag inom ett brett spektrum av branscher. Framställningen av denna typ av grafik kräver ofta väldigt mycket datorkraft. Vid rendering med renderingsmotorer som använder sig av raytracing algoritmer är aliasing ett medfött problem. Lösningen heter anti-aliasing som arbetar för att undvika aliasing artefakter som jagged edges eller Moiré-effekter med mera. En del av anti-aliasingprocessen är supersampling som ofta kräver mycket datorkraft.

This thesis deals with options about information technology in education, the starting pointbeing a project in progress, namely Ostindieprojektet. This is the first collaboration betweenDatatorget and Stadsmuséet in Göteborg. The research is built on a phenomenological approach.The "backbone" information is collected from qualitative interviews, conducted mainlyduring March-April 1995.The questions for the interviews deal with the opinions about the reasons with Ostindieprojektetand IT in education, what conditions required to complete Ostindieprojektet and the ITdevelopment, the availability of the material, how IT-use can affect education, possible qualitiesfor the student with IT-use and how IT-use can affect the role of the school-1ibrary as ateaching tool.Some key subjects examined in the thesis deals with governmental investigations, viewsabout pedagogic and knowledge, problem-based leaming, computer-based education and therole of the school-library. The research shows that the interviewers have the same opinionsas the above mentioned key subjects. In completing the thesis we hope we have created aforum for critical discussion..

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.
