This report is the result of a sub-project of a larger project to create a platform formathematical education. The sub-project focuses on authentication with associ-ated security, where security is emphasized. The project environment is Java EE 6where GlassFish 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.

This final-year project has been performed at Strix production Efterlyst. The task has been to make a page under their homepage, with a game application that?s supposed to be interesting and also have a strong connection to the TV- program. In the first part of the report, the reader will learn about the preparing work that was done before the work with the final game began. It is in these two test versions all the technical problems were tested, to finally be used or thrown away.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

This thesis is about the public library of Ulricehamn and the cultural activities at the library during the period from 1960 to 1998. We have focused on the study of the cultural activities. It begins with the foundation of the library of Ulricehamn and a historical background to it. It follows with the definitions of the public library and a historical background to the public library in Sweden. Then we present the goal of the public library in general and the goal of Ulricehamn's city library.

The purpose of this master thesis is to investigate if the mobile library has a similar role as the public library. To study this further we intend to examine the value and function of the mobile library. Answers are sought to the following questions: Can the mobile library be seen as a public library in a smaller scale? How do the users experience the value and function of the mobile library? What does the library staff think of the value and function of the mobile library for the users? What would the consequences be if the service of the mobile libraries would not exist? The method used was qualitative interviews. The groups of respondents are mobile library users and library staff.

The process of producing a video game is one that goes through a number of phasesduring the span of the entire production. One of these phases is the concept design phase,which is part of the pre-production. This phase is an important aspect of the productionas it is where all the different parts and ideas concerning the game are brought togetherto define what the game is going to be. Though a clearly important part of the videogame production surprisingly little research have been done on the subject of conceptdesign. This thesis presents what place concept design has in the overall game productionand how the design process is handled.

This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..

I denna text diskuterar jag produktionen av Hearty Horrors, ett spel programmerat och designat helt i flash. Jag diskuterar svårigheterna för de olika delarna i att skapa ett spel. Tankar och jämförelser mellan onda och goda karaktärer och vad man, som speldesigner, bör och inte bör göra för att få spelare att känna sig manade att spela vidare. In this text I discuss the production of Hearty Horrors, a game programmed and designed completly in flash. I discuss the difficulties of diffrent parts in the making of a game. Thoughts and comparances are made between evil and good characters and what you, as a gamedesigner, should and should not do to make the player want to continue playing..

Maxflo?desproblemet har ma?nga praktiska tilla?mpningar och probleminstanserna kan bli mycket stora.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Detta arbete har utförts på WM-data i Skövde och gick ut på att skapa ett ledningsinformationssystem i webbmiljö. Systemets uppgift var att förse användaren med information om vårdplatsbeläggningen på tre av Skaraborgsläns sjukhus. Systemet skapades som en webbapplikation vilken med hjälp av Java applets kommunicerar med databaser som innehåller informationen. Arbetet resulterade i en webbapplikation, en systemspecifikation för applikationen och en examensarbetesrapport..

The technology used in the development of web-applications is evolving at such rate that it has become more and more important to keep web-applications modern. If an application is based on a technical platform that is not renewed, the platform may over time develop into an obstacle in further development of the application. There may be compatibility issues and some of the code may be unnecessary due to abstraction, and therefore more time consuming to work with. Sometimes the reason may be that an application has been built to run, and is running on an application server that is no longer being maintained. The system can be large and modernization can cost a lot.
