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.

Our study is focused on how the public sector can collaborate with the private sector on a certain issue. The public sector wanted to create a project to increase bicycling in the municipality of Kalmar. Our problem was to develop a sustainable way to collaborate between the two parties. We managed to present a suggestion on how the public sector with communication could improve their Public Relations with the private sector and therefore letting the parties benefit from their differences, thus making it possible to release synergy.Using semi-structured interviews and a workshop, we could clarify the values and attitudes of the parties to bring forth the core values to develop a shared vision. Where the identified differences were found, we used a dialog strategy based on intercultural conflict management as a communication tool.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

This master thesis deals with the differences in the design of the environmental scanning between different kinds of organisations, as well as the demands and regulations etc. in the respective environments that influence the environmental scanning. The content of the environmental scanning and the organisation of the function are outside the scope of this study. Two organisations that do not have an organised function but are scanning their environment were chosen for the investigation. A model for conducting the environmental scanning developed by Frankelius is used to analyse the practice of environmental scanning.

AbstractSeveral of researchers have reflected that the school ought to be developed to a learning organization. A method as proceed from such a perspective and should be able to match a local child- and educations administration is problembased school development. To investigate in which ways a child- and educations administration prosecute a problem based learning inside the organization a case study was used as research strategy. The question this report gives answer to is:In what/which way works a child- and educations administration in a rural district with a method to fulfil a problembased learning.To collect empiric data a canvassing inquiry was accomplished among the child- and educations administrations group of management. According to the research result it can declares that there are good conditions for the organization to prosecute problem based school development, but there is yet a great deal to do before it´s can be said totally fulfilled.

"Infiltration of Waldheim" är ett spel gjort av David Lindell (grafik), Andreas Persson (programmering) och Mathias Jönsson (ljud och musik). Målet vi hade med projektet var att ha en spelbar bana med minst en vapen typ samt fiender att eliminera, allt ackompanjerat med pampig musik och en massa ljudeffekter. Jag kommer i denna rapport beskriva arbetets gång samt reflektera över vad som har fungerat och vad som varit mindre bra under projektets gång. Mina planer för spelet var mest att lära mig mera om framförallt AI samt arbeta mera i 3d. Spelet ska mest vara för mig själv, men med lite putsning och mera innehåll eventuellt användas vid jobb ansökningar i framtiden..

Bakgrund: KK-stiftelsen bildades 1994 och fick i uppdrag av den dåvarande regeringen att bland annat utveckla IT i skolorna. Vi har genom våra arbeten upplevt datorns intåg i verksamheten och har sett olikheter på användandet av denna. Media och forskningen har visat att IKT är och kommer att vara en viktig del i samhällsutvecklingen och utifrån detta fick vi uppslaget till denna studie. Syfte: Studien syftar till att undersöka om vissa specifika klasser har nått KK- stiftelsens vision, samt att se om det finns något orsakssamband till hur det ser ut i skolan idag d.v.s. sambandet mellan datoranvändandet i förhållande till ett konstruktivistiskt synsätt, yrkesrollen, kunskapssynen, kunskapen som krävs i framtiden, traditioner och undervisningsmetoder.

Sekretessbelagd.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

Irritable bowel syndrome (IBS) är en komplex sjukdom som yttrar sig på många sättoch i olika svårighetsgrad. Nuvarande behandling riktar sig mot att behandla varjesymtom var för sig. Hos patienter med svåra symtom är detta inte alltid tillräckligt.Efterupptäckten att tricykliska antidepressiva (TCA) kan lindra IBS hosdiarrédominanta patienter ökade intresset för andra antidepressiva läkemedel. Dettaledde till att selektiva serotoninåterupptagshämmare (SSRI) blev intressanta. SSRIpreparat har visats ha en smärtlindrande effekt hos patienter med IBS och en parallellhar dragits till signalsubstansen serotonin som finns i både hjärnan och tarmen.

Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.

The school is a place of work where teachers, with different tools, are supposed to teach their students for the future. In the study the teachers? opinions will be lifted when it comes to use of computers as a tool to teach the students how to read and write. The interpretation is that the use of computers is reflecting the development of society and the intention is to find out if computers will be used in a didactic purpose in teaching. We focused on getting knowledge about which different opinions there are among teachers in grade 1-3 when it comes to the use of computers as a tool in teaching how to read and write.

Rapporten huvudsyfte är att beskriva hur vi genom användning av språk och kommunikation har kunnat tillgodose våra användares krav på ett ärendehanteringssystem, samt på vilket sätt vi har använt artefakter för att kommunicera. Vi kommer att beskriva olika delar av projektet där språk och kommunikation har haft centrala "roller" och visat sig ha olika betydelse beroende på de personer som medverkar och i vilken miljö situationen har utspelat sig. Rapporten behandlar även hur resultatet av ovanstående har lett oss in i en utvecklingsprocess där vi försökt tillgodose användarens krav på bästa sätt. Vi kommer också att beskriva de kända och tidigare okända metoder som vi använt oss av för att uppnå vår målsättning, att överlämna en första prototyp av ett ärendehanteringssystem..

Utvecklingen av medborgare samt företags användande av Internet har ökat dramatiskt under de senaste fem åren. Det ökande Internetanvändandet ledde till att statskontoret 1999 fick i uppdrag av regeringen att ta fram olika förslag samt underlag som skulle ligga till grund för begreppet 24-timmars myndigheten. Tjänsten är beräknad att tas tillbruk i Sverige år 2005. 24-timmars myndigheten kommer tillämpa ett antal olika säkerhetslösningar, därav elektronisk signering. Denna utredning skall belysa hur stort inflytande säkerhetslösningen elektronisk signering kommer att ha på användaracceptansen av denna tjänst.
