This thesis investigates how a developer can move a desktop application to the web environment. The investigation also includes finding out what are the limitations of a web application and what is not possible to move to the web from the desktop. The question is whether there is any functionality that is gained or lost in the web application after the move.A survey has been conducted to find out what types of problems occur when moving an application from desktop to the web. The authors of this thesis have developed two prototypes for a company who wants to move a limited part of their current desktop application to the web in the future. The prototypes have been developed in Silverlight and ASP.NET.The survey has revealed that one of the disadvantages of web applications is the difficulty in working with local files and hardware on the computer.

Purpose: The purpose is to analyze if differences in technology and culture between the business divisions in diversified companies motivate a differentiated reward system. Method: The study has a case study approach.

Detta arbete är en magisteruppsats i Systemvetenskap med inriktning data och systemvetenskap, 10 poäng, vid Luleå Tekniska Universitet. Uppsatsen klargör vilka faktorer som avgör en användning eller icke-användning av Case-teknologin. Case-teknologin möjliggör ett ingenjörsmässigt närmande till mjukvaruproduktion och systemutveckling genom att tillföra nödvändig systematik, standardisering, automation och kvalitetssäkring. Ett stort antal undersökningar är gjorda genom årens lopp med syfte att förstå och förklara varför det som teoretiskt borde vara lösningen på problemet med undermåliga system inte tycks ha blivit detta. Resultatet av undersökningen tyder på att de variabler som Prekumar och Potter kom fram till i sin forskningsmodell ? relativa fördelar, kostnad, komplexitet, kompabilitet, produkt förespråkare, stöd från ledningen och operativ expertkunskap har störst påverkan på användningsbenägenheten av Case-teknologi..

In today?s society, safety in a workplace is an important factor to any organization. Focus on improving the working conditions by making them safer through technology is taking us into a time where we rely on technology to keep us safe. How well developed the technology may be, it is still not enough to keep us entirely from harm. Human error will always be a factor in the human interaction with a workplace.

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall.

Information technology is increasingly used in healthcare. New methods, such as apps and computer programs and Internet-based treatments are introduced to treat various medical diagnoses. Increased demand for help in mental illness means that it is necessary to develop alternative assessment and treatments to traditional treatments that may be offered by primary care and specialist psychiatry. Government and Local Authorities and Regions (SKL) have agreed to support, and treatment on the web is part of that development. The work is all about, and how Child and Adolescent Psychiatry ( Bup ) , use psychological e- services, and apps for the treatment of adolescents and the types of psychological e-treatments for adolescents are available in Sweden today.  Methods used are interviews and literature studies, where I examined the use of computerized psychological treatments in Västernorrland and Stockholm County Council.

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

Turbulens är ett väderfenomen som har orsakat många olyckor och incidenter. Speciellt farligt är klarluftsturbulens eftersom fenomenet ej är synligt för blotta ögat, samt att det kan uppstå mycket plötsligt. Mycket pengar och resurser har lagts ned för att ta fram system som skall kunna detektera och automatiskt rapportera turbulens. Denna uppsats beskriver kortfattat hur några av dessa system fungerar samt hur systemen skall bidra till att piloter lättare skall kunna förbereda för eller undvika turbulens. Uppsatsen beskriver system för prognostisering, detektering och automatisk rapportering av turbulens med tyngdpunkt på klarluftsturbulens..

Detta magisterarbete fokuserar på kravhantering i systemutvecklingsprocessen. Mer specifikt handlar det om uppdatering av kravspecifikationen då nya krav tillkommer. Detta är en aktivitet som ofta förbises och jag har velat se varför samt vilka konsekvenser det kan leda till. Det referensföretag där undersökningen utfördes är ITT Flygt i Emmaboda och Solna, som har intern utveckling av system för sin verksamhet. Tillvägagångssättet i undersökningen har främst varit intervjuer, men även studier av de dokument som finns i verksamheten.

The purpose of this MA thesis is to examine the computerisation of sources that are of interest to genealogists. The primary focus of the thesis is an empirical study, by using a questionnaire addressed to 118 genealogical societies in Sweden, in order to find out what kind of computerisation is being performed by these genealogical societies and what their opinion is of the computerisation of sources of interest to genealogists. The result of this questionnaire has shown, together with printed and electronic material, that there is a good deal of interest from genealogical societies in the computerisation of sources. About half of the genealogical societies who answered the questionnaire are computerising sources themselves and the societies have a positive view in general of the computerisation that is being done and of the increased usage of modern information technology in genealogy. There are on the other hand certain issues that are being discussed such as the important question of the quality of the computerised material.

Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).
