As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Library architecture today is a complicated history. Public libraries are no longer merely a place for book storage, but also a virtual library a social meeting place and a place for study. All these diverse tasks and roles emerge in the democratic designing process of a new library and also transform into the architecture. The underlying process is the evaluation and negotiation of the libraries overall tasks and ideas, ideals and values. Multiple ideologies are incorporated in library architecture.

I denna uppsats underso?ker vi hur principer fo?r spelmekanik pa?verkar anva?ndares bena?genhet att bidra med inneha?ll pa? interaktiva webbplatser. Genom en empirisk studie av kvalitativ art ja?mfo?r vi tva? versioner av en testsajt, med spelmekanik implementerat i den ena versionen. Vi kommer fram till att spelmekanik fo?r att motivera anva?ndare att skapa inneha?ll kan designas utefter tre huvudsakliga delar; regler/struktur, ma?l och delma?l samt vinster. Regler och struktur a?r vad som a?r mo?jligt eller tilla?tet att producera samt kvalitetskrav pa? inneha?llet.

In my study I have participated at the Fifth Dimension / Active Worlds site in Villa Gymnastiken in Ronneby, where I have worked both as an assistant to the project leader and as a researcher, but also as a participant together with the children. The children are working in a virtual world called Femtedim, created in a internet-based program named Active Worlds Education Universe. The Femtedim-world are bridging together two physical worlds in Ronneby and Copenhagen. My main focus is on an intervention that occurred in the 12th of March when the research-team in Copenhagen, which runs the project in Denmark, decided to create a new challenge for the children since some of them started to get bored. They added gravitation to the Femtedim-world, which lead to a few different reactions among the children. Most of the children didn´t like it and were very hostile towards the idea that they would not be able to fly around freely in the Femtedim-world.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

Avatarer är vanligt förekommande i datorspel och används för nöjes skull men avatarer används även i seriösa spel. Rapporten undersöker hur en persons självkänsla och body image kan stärkas med hjälp av en avatar och vilka egenskaper avataren behöver ha. Undersökningen genomförs som en litteraturstudie. Slutsatsen är att det troligen går att skapa en avatar för detta ändamål, men att det är många aspekter att ta hänsyn till och att det inte är helt självklart vilka val som behöver göras. Viktigt verkar dock att användaren själv får välja sin avatar, att till exempel typen av klädsel påverkar liksom avatarens längd.

The network with its virtual business structure challenge the established vertical business structure. Part of the network theory that has developed focuses on relationships that forms B2Bnetworks. One way to create a B2B-network is for independent businesses to form a organization promoting co-operation. For co-operation to be successful it requires well thought-out actions, but a lack of how these actions are implemented have been noticed. This study explores how encouragement of co-operation can be done practically.

The purpose of this study is to understand the knowledge of the school counselor and their room for manoeuvre regarding cyberbullying among students. We have used a qualitative method, which consists of eight semi-structured interviews with six middle school student counselors and two high school student counselors, in a middle-sized municipality in Sweden. Our study showed that the school counselors have limited knowledge about cyberbullying due to the fast development of the internet, and limited time in their work. The limited knowledge affects the school counselor?s way of work, and how they use their room for manoeuvre on cyberbullying.

Detta är ett examensarbete inom informationsdesign med inriktning mot rumslig gestaltning. Syftet med min undersökning var att ta reda på hur ett kvarter i Eskilstuna kan formges till virtual reality (VR)-mediet, så att det går att få en upplevelse av hur en stadsplanering skulle kunna se ut om den genomfördes i verkligheten.  Resultatet från min studie är grundat på, prototyping, intervjuer, och en enkät. Min undersökning visade att för att det ska gå att få en upplevelse av ett stadsrums utseende efter en nybyggnation, bör representationen formges efter tänkt målgrupp och budskap. Felaktiga eller för många informationsgivande detaljer kan leda till att fokus hamnar på information som inte är nödvändig, eller till och med felaktig, för att förstå hur kvarteret kan komma att se ut efter en nybyggnation.  För lite information om olika detaljer eller för låg detaljrikedom kan leda till att representationen blir svårtolkad. Min undersökning visade också att visuella detaljer som är svåra att formge, bör kompletteras med t.ex.

In this thesis recruiter?s attitudes and usage of social media within the media business has been examined. The purpose was to find out whether a certain type of behavior in social media could or could not lead to a future employment. How much weight is put on the virtual identity and what does recruiters look for when the look someone up on the internet. Personal interviews with recruiters were done in six different media companies in Stockholm to find out how they used social media when searching and employing new employers.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Sweden?s energy consumption is divided into three major sectors. One of them is the industry sector. One third of Sweden?s energy consumption is converted in the industries.
