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.

The purpose of this paper is to investigate how a small company manages its information, primarily the organization of digital documents. The two dominating themes are classification and information politics, the former in the context of a corporate environment and the latter to help us to describe the situation at the company. The method used has involved observation of the company's current computer network structure and also interviews with six employees at different levels in various departments at the company. The result of our investigation has been the realization that, although logical structure is important when organizing documents in a digital environment, it is also necessary to have rules regarding its implementation..

Dataspelsproblematik är ett eskalerande problem som har visat sig påverka många unga människors utveckling och välbefinnande. Syftet med denna studie var därför att undersöka ungas dataspelsproblematik, vilka konsekvenser ett överdrivet dataspelande medför samt vilken behandling som ges till unga med dataspelsproblematik. Empirin erhölls genom kvalitativa intervjuer med professionella som arbetar med denna typ av problematik vid verksamheterna Game Over och Theory in Action. Resultatet visade att dataspelsproblematik idag inte har en bestämd definition och att det är ett problem som inte är tillräckligt uppmärksammat. Synen på orsaker till dataspelsproblematik hos unga är komplext då det kan tänkas bero på många olika faktorer.

Recent papers and bills from the Swedish Government deal with the possibilities  of giving all Swedish citizens the possibility of their own creative actlvities in the cultural sector. This work is about where such actlvities shall be placed in order to make them obtainable  for all. As an example of creative work this work takes computer-based music-making. At the public library in Odense, Denmark there is a weil functioning sound workshop where the public gets the opportunity of making music with some assistance from the staff. This work shows  that also in Sweden  the public libraries are the most suitable  institutions  for placing studies for computer-based music-making  for the public depending  on the public libraries'  traditions in adult education.

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

This essay describes the philosophy of science that Thomas Kuhn puts forth in his work The Structure of Scientific Revolutions. The question is, does his description of the scientific paradigm work as well today as in the examples he gave in the book?The conclusion is that there are certain factors that make for a number of differences between science today and, for example in the seventeenth century. There is also a growing theory or vision of a post normal science laid developed by among others Jerome Ravetz. This theory or vision is an idea of a science close to peer-communities and fast as well as critical decisions involving opposite values..

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.

Denna uppsats avser att belysa frågan varför prototyper är ett viktigt verktyg i en utvecklingsprocess av ett mobilt system. Fördelar och nackdelar som verktyget kan innebära behandlas och olika tillvägagångssätt beskrivs. Arbetet med detta baseras i ett praktiskt utvecklingsprojekt på IT-kunsultföretaget Citerus. Projektuppgiften var där att genom en informationflödesanalys definiera olika flaskhalsar i informationsflödet på olika hotell för att sedan föreslå ett effektiviserande system. Projektet koncentrerades vidare på städpersonalen och deras arbete. Utifrån fortsatta studier föreslogs ett mobilt system som ger städpersonalen information för att lättare och effektivare göra sitt jobb. I flera olika forskningsdiscipliner som berör design och systemutveckling förespråkas ett utvecklingssätt med hjälp av prototyper.

Swedish healthcare systems have endured harsh criticism from healthcare professionals because of their inability to understand healthcare processes. These systems have been identified as significant time consumers, and Swedish healthcare is therefore facing a major challenge to assure patient safety. The following paper is based on a workplace study, which aims to examine healthcare systems? impact on physicians? practices. Our findings show that physicians spend substantial amounts of time chasing information, rather than managing information and pursuing healthcare.

En grafisk ritare i flygande system måste under dess utveckling verifieras för att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara identiska mot referensbilder genererade av en fungerande ritare så ställer det krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att automatisera den processen är i högsta grad intressant för att minska kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan uppstå, däribland ett sätt att utvinna eventuell transformation mellan två bilder..

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..

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.
