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).

The aim of this study is to describe what teachers and principals experience in schools regarding threats, violence and harassment towards teachers. A phenomenographical inspired approach has been used to describe and analyse the conceptions of five teachers and five principals. The findings of the study indicate that there is no impending risk for teachers to suffer from violence, threats or harassment. However, it does occasionally happen, and the findings of the study indicate that there are some factors that increase the risk. The major three factors are: fear, personality and inexperience.

Violent crime can traditionally be classified as a reactive or an instrumental aggression. A reactive aggression is often characterized by some sort of provocation by the victim and the act is impulsive and the offender reacts by harming the victim. The provocation can be a threat, an insult or an attack and the act can be said to be a reaction induced by emotions. An instrumental act of violence however, often described as planned, targeted and emotional cold. The goal of the act can be to acquire money or power to maintain their status.

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

This rapport examines six Swedish workplace unions, in manufacturing internationalised companies, degree of internationalised trade union work. The report is based on interviews with local shop stewards. All local workplace unions were in some form internationalised. They were placed in three different groups of strategies: Passive, Tactical and Strategic. The Passive union only tried to get information; the Tactical unions were reactive against initiative from company management and used the channels provided of Industrial Relation laws.

The purpose with this thesis is to analyse images in the confirmationbook Via Mystica from a gender perspective. By using two different ways to analyse the pictures, a content analysis and a semiotic picture analysis, the result was as follows: The pictures of men an women fortifies the construction of gender. The girls in the pictures are represented as caregivers and comforters, while the boys are represented as strong and tough. The four pictures from the semiotic picture analyses showed how easy it was to categorise the men and the women in the photos in opposing stereotypes. The women are percieved as weak and submissive while the men were either strong criminals or a strong hero.

In this thesis, high quality adverts are examined from the perspective of the advertisement contest Guldägget. The study discusses award-winning advertisement, both in terms of content and design, according to Guldägget?s jury members, industry experts and various theorists. Semiotics is used to analyse Guldägget?s winning adverts.

We read different kind of texts every day. We can for example choose to read a book or to watch a film. While we read we can receive and interpret texts. That?s means, for example, that we can have different envisionments about the drama and the film based on it. Based on Langer?s reception theory about ?envisionments?, I?ve wanted to examine and clarify the differences and similarities of envisionments between two texts.

This essay deals with classification of images using the subject classification system Outline. This classification system is used in regional museums and they do often have large collections of pictures. The regional museums have their main focus of culture history. The purpose is to look at Outline from four different aspects: 1. In what way is the system constructed looking at classification theory, 2.

The picture book is the children's first contact with the world of literature. The aim of our study is to look at how children and adults are portrayed in the picture book, from a gender perspective. Our aim is to critically examine how girls and boys, men and women are presented when it comes to both characteristics and appearance. Our research also focuses on how the text and images complete each other and we conduct a qualitative text and image analysis. We use Nikolajevas (2000) analytical model for picture books and previous research that already exists within the subject.In our paper we have clarified the concepts related to gender: gender, gender roles, gender equality and the picture book.

This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

This thesis presents a comparative study of image registration at two picture collection libraries. The two registration systems are analyzed as to the theoretical principles behind them and their practical application, and related to theoretical tools for subject analysis and bibliographic standards. While a growing number of picture collections now digitize their material, generally accepted standards and methods for the registration of digital images are still lacking. Many different systems coexist, often developed in-house in response to ad hoc needs and based on traditional registration tools created for textual documents, resulting in internationally incompatible mixed-format systems. The two picture collections examined here, however, have opted for similar, standardized tools for registration and subject analysis, and while there are differences in their application and focus, they have both considered issues of cross-system compatibility.

My purpose with this thesis has been tostudy the intersection between Landscapearchitecture and Land Art. They both relateto the landscape in some way whetherit is to the urban landscape or thenatural landscape.What tangent points are there betweenthese two subjects, and can you learnsomething of the artists approach to thelandscape?Land Art is an art movement that began inthe late 60?s, what links are there to thecurrent landscape?Last summer, I travelled around the U.S.for a month and visited the three classicLand Art projects. Lightning Field in NewMexico, by Walter De Maria, Sun Tunnels inUtah, by Nancy Holt and the Spiral Jetty,also in Utah, by Robert Smithson.The sites where visited from half a day upto 24 hours and was described and analyzedwith text and photographs.To visit these sites has been crucial formy thesis and will affect my future workas a landscape architect. The use of themethod has been a thought of mine for along time, particularly to analyze ordescribe a landscape with images.

St. Jude Medical Inc is one of the worlds leading companies in the medical technology area with cardiovascular devices as its specialty.Manufacturing implantable medical devices such as Pace Maker Electrodes requires complex design, safe processes and well trained operators. User friendly manufacturing operations are a necessity.Lately there?s been an increase of the manufacturing volume which also increased the number of operators. More operators need to be trained and cross-trained.
