As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.

Uppsatsen försöker kartlägga hur och om datorspel kan användas i samma syfte som skönlitteratur i den litteraturundervisning som GY11 föreskriver. Fokus ligger på beröringsytor mellan skönlitteratur och datorspel gällande lärande; främst identitetsskapande, moral och etik men också stilistiska drag och litteraturvetenskapliga begrepp. Med två exempel, Fallout: New Vegas och Grand Theft Auto IV, visas hur berättandet i datorspel kan ge mediet en plats i gymnasieskolans litteraturundervisning, samt hur immersion, perspektiv och interaktivitet kan ge spelare något som inte skönlitteratur kan ge läsare..

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..

Artificiell intelligens integreras idag i alltfler tekniska system. Trots det, ?r det fortfarande sv?rt att i praktiken implementera modeller fr?n grunden p? grund av h?ga resurskrav i form av data och ber?kningskraft. Detta motiverar s?kandet efter effektivare modeller. I denna artikel unders?ks Kolmogorov Arnold Networks (KANs), en alternativ arkitektur av neurala n?tverk och j?mf?rs med traditionella arkitekturer som multilayer perceptrons (MLPs) och faltningsn?tverk.

Internet består av väldigt många webbplatser där både kvalitet och kvantitet varierar. Dagens webbplatser är ofta kompakta genom att de innehåller mycket länkar, information och grafik. Detta medför att sidorna blir röriga och ger för många synintryck för användaren. Det blir svårt för användaren att ta till sig informationen och att tyda budskapet. I detta arbete utreds hur en webbplats bör se ut för att vara så tydlig som möjligt gentemot användaren.

Det finns åtskilliga faktorer som medför svårigheter när informationssystem skall bli säkra. Bland dessa faktorer finns bland annat att säkerheten inte är användarvänlig. Vi har därför i denna uppsats undersökt varför användare upplever problem med en höjning av informationssäkerhet. För att undersöka detta har vi stu-derat ett projekt som heter FSA (FörbättradSäkerhetsArkitektur) och som genomförs på Luleå tekniska universitet. Utifrån denna undersökning kan vi konstatera att användarna upplever flera problem som en följd av FSA-projektet.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

High school students of today frequently come into contact with the English language throughradio and television. Many students even manage to read instruction manuals and understandhow technical devices work, such as, for example, computer games. However, most teachersunderestimate their students? ability and persist in using Swedish to explain how the Englishlanguage works. I have analysed how high school students manage when they take an Englishgrammar test in English.

Detta är rapporten för hur IF Trions hemsida kom till och utvecklades. Från det att iden kläcktes tills det att hemsidan var helt färdigställd. Arbetet bygger mycket på de olika säkerhetsbrister som en hemsida kan ha, till exempel hur lösenord ska hanteras. Med avseende på detta så ingår ett avsnitt i rapporten om de vanligaste säkerhetsproblem som man kan tänkas stöta på under uppbyggnadsfasen och exempel på hur man kan lösa dem. PHP är det programmeringsspråk som IF Trions hemsida är kodat med. För att göra det lättare att välja vilket programmeringsspråk man ska använda sig av när man ska börja koda en hemsida så ingår ett kapitel som tar upp fördelar och nackdelar om PHP och ASP.

In today's society there is a significant focus on energy efficiency. Despite this, people leave lamps, televisions and computer screens etc. powered on unnecessarily. The goal of this project is to build a simple prototype for home automation where a user, via an application on a mobile phone, can switch on and off the power of an electrical products in the home and as well as being able to check whether such products are switched on or off. The prototype will also collect data on power consumption for these electrical products.

Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

The aim of this thesis is to investigate how libraries market themselves in social media and why they do it. I have studied a certain public library?s process of introducing social media into its marketing mix, the preparations for this process and the effects of these marketing methods.The theoretical framework for this thesis is based on relationship marketing, a theory which focuses on relationships, networks and interaction. My main method has been semi-structured interviews with a librarian at the relevant library, with the manager of the library and with the head of the municipality?s department of communication.The results of my studies show that marketing on social media is a positive and important thing for libraries.

Vårt mål är att förhöja deltagarnas upplevelse i levande rollspel (även kallat lajv). Idag finns det inga möjligheter att visualisera övernaturliga förmågor. I den här rapporten visar vi ett exempel på hur detta kan realiseras med hjälp av teknik. Vi har inriktat oss på att simulera alvers övernaturliga hörsel. Levande rollspel är mycket känsligt för störningar från ?världen utanför?, exempelvis modern teknik och språk.

Abstract (in English)The work that lead to a CE- marking and the creation of a total drawing foundation on an existing machine carried out on the company Polytec Composites Sweden AB in Ljungby. The company have design an machine that exist in six example that runs in the production. To be able to use the machine the company have to work out a CE-marking. The process that summed up all the document that needs for the machine to make a CE-marking. The documentation includes a total drawing over the machine and a risk analysis performed by a group employers on the company.

Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.
