Windows, RedHat och IPv6 : ett test!

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

Design och implementation av konfigurationsverktyg för funktionsblock

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.

A comparison between techniques for color grading in games

Color has been significant in visual arts for as long as the art-forms have existed. Still images and movies have long used colors and color grading effects to affect the viewer and characterize the work. In recent years attempts have been made to bring these techniques of stylizing also to interactive games. This dissertation aims to compare two different approaches of performing real-time color grading for games. Focus is put on examining the two ways from a number of different perspectives and from there draw conclusions on advantages and disadvantages of the approaches.

?Contract-For-Difference? - en studie om den optimala faktiska marginalen

We have two aims with this thesis. The first aim is to describe CFD as a financial instrument in detail by highlighting its potentials and disadvantages. The second aim is to try to find the optimal real margin for each of the underlying stocks.We have adopted an inductive approach, combined with a quantitative method. We have worked with data and tried to come up to conclusions from the results we got.The conclusion of our thesis is that it is optimal to enter a CFD-contract with own capital covering at least 20 % of the value of the contract..

Webbsystem för matprisjämförelser

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.

I Microsoft Dynamics AX ? databasaccess, kommunikation och tjänster för Commerce Runtime

Examensarbetet undersöker den nya versionen av affärssystemet Microsoft Dynamics AX R2 2012 och dess plattform Commerce Runtime och analyserar dessa ur perspektiven arkitektur och kommunikationsmöjligheter. Examensarbetet undersöker systemets arkitektur och implementerar tre metoder för att visa upp kommunikationen mellan komponenterna i systemet. Undersökningen avgränsar sig dock till de områden av systemet och plattformen som har med butikslösningen att göra. Undersökningen går hand i hand med implementationen. Implementeringen sker löpande under arbetet för att säkerställa att undersökningen stämmer.

Bostadsbranschens väg in i upplevelseekonomin : Kan fastighetsmäklarens arbete omvandlas till en säljande upplevelse?

The civilization has taken a step from the industry society to a service oriented culturewhere the physical differences between different products have decreased in value for the customers. The differentiation is more about senses, esthetical symbols and design. Modern economy is more and more focused on consuming and produce dreams and lifestyles. Maybe are we ready to face a new era; the society of experiences?Can the trend that is striving towards experiences really be adapted to all markets? This question started our quest to see how the real-estate market would be able to be adapted to this new economy.

Gulliver Simulation - En systemarkitektur f or n atverkssimulering av

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.

Development of real-time RT-PCR for the detection of human sapovirus in foods

Food-poisoning is a major health problem and an estimated half a million Swedes are food-poisoned annually, with acute gastroenteritis as a consequence. One of the major causes of contaminated foods is related to food- and waterborne viruses. To be able to trace back the source of contaminant, the method of detecting viruses must be specific and sensitive. No standardized method for detecting foods for sapovirus exists today. The aim of the work described in this bachelor thesis is to implement and opti-mize a real-time RT-PCR method for the detection of all genogroups of human sapovirus in foods.

Undersökning om spelares uppfattning om latency i realtidsstrategispel

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

Produktutveckling av koncept för isbanesystem

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Bedömningsgrunder och reningskrav för avloppsreningsverk, 25-2000 pe, i Laholms kommun

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

Verkligt värde : implementation of IAS 40 in quoted real estate companies on the Stockholm stock exchange, and effect on the company key ratios

Background: Within real estate companies assets according to IFRS/ IAS 40 should be valued at fair value, to compare with previous valuation criteria according to which real estate should valued at cost. Two models can be used within IAS 40, these are value at cost and fair value. When valued at cost the real estate value in the balance sheet should be specified at cost. The method chosen by the company should be used for all real estate within the company except for the premises used by the company. Purpose: The purpose of the study is to analyse and evaluate how real estate companies experienced the problems that arose when converting to IAS 40, and to analyse the effects on the companies key ratios as a result of the change of accounting method.
