I detta arbete framlägger vi ett designförslag på hur ett diskussionsverktyg som stödjer ljud- och bildkommunikation kan se ut. Ett förslag som förbättrar och förenklar den distanskommunikation som idag sker med hjälp av mobiltelefoner, videokonferenssystem samt webbkameror anslutna till persondatorer. Den design vi föreslår möjliggör för mobila användare att visuellt föra flerpartssamtal med hjälp av PDA:er. Vårt designförslag har fått arbetsnamnet CU2 (see you too) och är tänkt att fungera i tredje och/eller fjärde generationens mobila nät. Vi har valt att genomföra vårt magisterarbete på företaget A Brand New World i Kista, Stockholm. Företaget utvecklar och säljer system inom mobilt Internet..

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

In this paper we examine how young women present themselves on their weblogs. The main purpose of this study is to get their own opinions and thoughts about their own blogging, to see if we can find norms for how they present themselves and how the presentation online matches themselves offline. We put this in relation to information technologies, social software and Computer mediated communication, CMC. It´s also in our interest to see how the phenomenon of blogs, its role and methods of communication have changed and developed in the last few years, and whether there are differences in the way people use it according to age. The major finding is that, unlike previous research, the women in our study tend to be themselves in their weblogs and they do not manipulate their identities.

Contents:The evolution of today?s computer influenced society has taken giant steps towards virtual reality, game addictions and the possibility of not having to meet the people we communicate with. What is a reality today?To give a more concrete image of our question we?ve chosen the online game World of Warcraft as an example and to describe our connection to an alternative reality. We have performed different investigations, interviewed both gamers and non gamers, all this to give us the opportunity to see if the term reality has started to change in a direction that will allow us to call this alternative world a reality, or if it?s just a world wide phenomena of for example gaming addiction.

Smartphones have become more common as business tools within the workplace. With its many features and great flexibility, the smartphone has stormed the business world and become an alternative or complement to the laptop. As these mobile units' popularity has increased, the interest of businesses to invest in this new technology has increased, but has security kept up with the technology developments?This study aims to conduct a study to see if the companies in the IT industry have the same safety awareness for smart phones to laptops.The study shows that companies have greater safety awareness and higher safety requirements for laptops than smartphones. Meanwhile, both end-users and management are well aware of the risks and threats that the smartphone is facing..

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

Tången 2 is a building situated in Stockholm, Sweden. It´s built in the 1930s and contains both residences and businesses. The property owner, Diligentia AB, wants to lower the energy use in Tången 2. This report consists of an energy audit which clarifies the specific circumstances linked to Tången 2. Collected knowledge is then used, together with the results from the literature study, to decide energy measures to proceed with.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Some people do not have the opportunity to visit a physical exhibition because of limited time or long travelling distances, it is here the need for a web-based exhibition arises.This dissertation describes the development of an interactive web-site representing a part of a physical exhibition of over 200 interviews on different peoples immigration to inner Scandinavia. The interviews contain text, audio clip, pictures and video clip.The website contains modern programming technologies such as HTML5, ASP.NET MVC3, SQL, JavaScript and jQuery.A cover of the technologies used and how the project has been designed and implemented is explained in the dissertation. In the end of the dissertation we discuss about how the result of the project follows the goals we set up in the start phase. The result of this project is an interactive and easy to use web-site showing a part of the physical exhibition online. An easy administration to insert new information and edit existing without any major computer knowledge..

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.
