At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

Syftet med uppsatsen var att undersöka attityder och förhållningssätt hos en grupp lärarstude-rande till hur Internet används för undervisning och som verktyg i det framtida arbetslivet. Resultatet visar att inställningen inte är en odelat positiv till detta vilket går att tolka på olika sätt. Datorvanan hos de blivande lärarna varierar kraftigt från nybörjarnivå till mycket van användare. Källkritik är något som tas upp av samtliga blivande lärare som viktigt att tänka på, liksom etiska frågor. Essensen av undersökningen visar på en osäkerhet hos blivande lära-re inför hur innehållet på Internet kan användas i undervisningen.

This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.

The main purpose with this study was to investigate how study- and careers counselors active in primary school, secondary upper high as well as colleges describe regarding satisfaction of assignments and suggestions on their development. The study also included in what extent pure guidance tasks cover these assignments as well as what criteria affects these.Six study and careers counselors were interviewed during this study, all active in the three separate educational programs. Their responses regarding what tasks are included in their assignments as well as experiences are in line with previous research. The conclusion drawn from this study shows deviational results in-between the three educational programs, this regarding guidance tasks in their assignments. The conclusion strongly pinpoints that criteria as ?time? and ?need of guidance? affect to what extent guidance tasks fills these study and career counselors assignments..

The purpose of this article is to explore the technologies of government that are created within gender disorder assessments as an institution. I have done so by utilizing Norman Faircloughs discourse analysing instrument ?communicative action?, which focus on the social institution as relational.The material is strategically chosen by gathering texts from the Swedish state, the psychiatric clinics, NGO:s and by performing interviews with transsexual patients.When analysing the communication of the main agents, I have concluded that practices highly are a result of repeating text and speech inside the institution. The psychiatric assessments can also be seen as an illustration in changes in how citizens are governed in advanced liberal societies, where the role of the state has been gradually reduced in favour of other agents.I consider that the change illustrates an ?acting at a distance?-mentality where the patient is introduced to participate in the definition of the care in what I call ?negotiation as a technology?.

Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

This thesis presents the work of developing and testing a programming tool specially designed for children. The purpose of this tool is to make children capable of creating visual simulations and games that consist of actors interacting in a virtual world. The name of the programming tool is Behavior Cards, which comes from the fact that actors are programmed by giving them cards representing different kinds of behaviors. Behaviors are to some extent pre-programmed and can include general events specifying how the actors should act in different situations, in contrast to specifying every possible situation that can occur. The idea is that Behavior Cards should be easier to use than a more traditional text based programming tool, but it should also be expressive within the domain of visual games.
