This thesis investigates how Ericsson AB should do to achieve fast and secure handover when roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. The premise was that they wanted a standardized way of handling the roaming issue. At the outset the 802.11F standard looked like a good alternative (in fact the only standardized alternative).

Of all observable societal trends, the proliferation of standardizing processes is striking. Auditing standards are an illustrative example of this. Not only privately owned companies must today make available numbers and key figures to satisfy needs of information and knowledge. Government agencies are increasingly conforming to this trend, adopting standards for quality assurance and monitoring, producing numbers and annual reports ? despite their somewhat ambiguous task and role.

En svensk standard, SS 812310­ ? Dimensionering av fiberbetongkonstruktioner, har nyligen tagits fram som skall säkerhetsställa kvalitén och underlätta dimensioneringen av stålfiberbetongkonstruktioner. Tidigare har det inte funnits en dimensioneringsstandard som täcker in området stålfiberbetong. Det har varit upp till enskilda konstruktörer att dimensionera utifrån metoder angivna ur ?Svenska Betongföreningens rapport nr 13?.

Denna uppsats handlar om öppna förskolan, en verksamhet för barn och föräldrar som vissa kommuner väljer att tillhandahålla. Trots att verksamheten funnits drygt 30 år, är den sparsamt utforskad. Uppsatsarbetet har därför inriktats mot ett explorativt sökande efter olika föreställningar om öppna förskolan. Föreställningarna har på formuleringsarenan eftersökts i tryckta källor, och på realiseringsarenan genom en etnografiskt inspirerad fältstudie i två öppna förskolor. Syftet har varit att uppnå förståelse för arenornas föreställningar om öppna förskolan och hur dessa föreställningar förhåller sig till varandra.

The aim of this study is to widen our knowledge about the basic idea about having an open preschool for adopted children as understood by parents of adopted children and a preschool teacher. Sweden has a large number of international adoptions, in an international comparison among the highest numbers of adoptions per capita. Interviews were carried out with seven adoptive parents and one preschool teacher teaching at a special preschool for adopted children. It was found that adoptive parents had no particular problems with placing their children in an "ordinary" preschool. However, they choose to place the children in an open preschool solely for adopted children because of the possibility of sharing similar experiences as parents and children as well.

This report was made for the company HordaGruppen AB to investigate how information security was handled. This report fits in the Master program of Internet Technology at School of Engineering in Jönköping University in Sweden.The question at issue was how you protect your information against different threats. One question was how to make an information security policy and which guidelines you can follow in the Swedish Standard, SS-ISO/IEC 17799:2000.Another question was to investigate the information sources at the company and which threats there are against it.The work begins with a presentation about information security for the chief of information and the chief of quality in the company. The next thing was to do a survey of as thing are at present with a tool from Länsteknikcentrum called ?Infosäkpulsen?.

One of the most crucial entries in the financial statements is revenue. Despite the importanceof revenue a lot of mistakes are made concerning this entry because of the extensive room forjudgements. Especially in the construction companies where a lot of differences exist due tothe fact that different standards are used for similar business transactions.The research concerning IFRIC 15 and the new upcoming standard for revenue recognition isnot very extensive. Studies including both IFRIC 15 and the new standard are even morelimited. Therefore this study aims to compare the effects of IFRIC 15 and the new upcomingstandard for revenue recognition, Revenue from Contracts with Customers, in three Swedishconstruction companies.

The main aim of this paper is to consider the possible effects of a transition to a new accounting standard for goodwill. According to IASBs Exposure Draft of Proposed Amendments to IFRS 3 Business Combinations there is an inconsistency in the currently used purchased goodwill method. The full goodwill method is considered to be a superior alternative and is therefore suggested to become the standard from 2007. This paper comprises a quantitative study of the effects on certain key ratios for companies listed on the Stockholm Stock Exchange, arising due to the proposed transition. The period examined is 2004 and 2005.

Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.

Bakgrund och problem: För att företag ska klara sig i den hårda konkurrenssituationsom råder idag krävs att de ständigt förändras. Dessa förändringar bör genomföras påett sådant sätt att de gynnar företagets prestation genom att öka medarbetarnasmotivationsnivå. Att dra nytta av företagets humankapital blir allt viktigare då det somdriver lönsamhet och tillväxt i ett företag rör sig från utnyttjandet av fysiska resurser tillatt använda sitt icke?materiella kapital optimalt. Utmaningen företagen ställs inför idagär att ständigt förbättra sin prestation för att locka kunder och klara konkurrensen.

På lång sikt är en ekonomisk tillväxt driven av teknologiska förändringar samt innovationer. Teknologin har gett oss möjligheten att bli innovativa genom helt andra vägar, där fler samarbeten sker över gränser. Open Innovation är ett fenomen som bygger på öppet samarbete mellan organisationer och externa aktörer. Mer transparens och öppenhet för externa kunskaper kan generera nya värden och bidra till den interna utvecklingen. Förekommande exempel på detta sorts samarbete är många, där syftet kan vara att tillsammans skapa nya produkter och eller utveckla nya marknadsföringsvägar.

AbstraktRöntgen är ett område där man ställer frågan om processen skulle kunna automatiseras för att göra den enklare för sjuksköterskor. På så sätt ökar antalet patienter som kan röntgas eftersom det skulle gå snabbare. Med hjälp av datorseende och en servostyrd röntgenkamera kan man förverkliga delar av dessa drömmar genom att låta röntgenkameran själv justera sig efter en patient och även flyttas till en vald kroppsdel.Här undersöks och testas open-source biblioteket OpenCV. En prototyp på ett automatiskt system tas fram med syftet att testa OpenCVs funktionalitet och besvara ett antal frågor:Hur kan röntgen automatiseras genom användning av open-source programvarubibliotek med inriktning på bildbehandling?Vilka för ? och nackdelar kan användandet av ett datorseendebibliotek vara?Kan man med dagens teknik utveckla en automatisk lösning som kan göras till en kommersiell produkt?.

Media has power and impact. It is therefore important for managers to be able to handle media storms when they arise. If not, the brand can be affected negatively. It is managers who should learn to handle media storms because the managers constitute an important part of the external face of the company. Because it is managers who should learn to handle media storms it is interesting to study how media storms should be handled from a theoretical management-perspective.

Computer animated faces have found their way into a wide variety of areas. Starting from entertainment like computer games, through television and films to user interfaces using ?talking heads?. Animated faces are also becoming popular in web applications in form of human-like assistants or newsreaders. This thesis presents a few aspects of dealing with human face animations, namely: editing, playing and transmitting such animations.

Arbetsförmedlingen is the Swedish national authority responsible for the work politics, and its main purpose is to create and build a solid and sustainable job market.Economic crises together with changes in the society and in the organization over the past few years mean that the unemployed individuals that come in contact with Arbetsförmedlingen are no longer a homogenous group. A lot of effort is put into helping those who may find it difficult to enter the work environment, such as youths (19 ? 26 years old), people who have been unemployed or on sick leave for a long period of time, people with disabilities or immigrants who are newly arrived in Sweden.A harder social and economic climate can lead to frustration among the unemployed which mean that security measures at the offices has had to become adjusted. Local offices now have a public area where they have meetings with their clients and a locked open plan office space to which the public have no access. Working within an open plan office environment can cause health problems, mostly due to the constant background noise that comes from people having conversations on the phone, or with each other.
