To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

Our study emanates from a socio?cultural perspective on learning and aim to describe and comparetwo different upper secondary school classes and their work with information literacy as a socialpractice in project work and their use of ICT (information and communication technologies). Thequestions at issue in the study are; how the pupils handle information seeking processes, whatdifferences and similarities can be observed in the two social practices and which consequences thesedifferences have in an project work environment.Our choice of research methods to collect data consists of both observations and interviews withpupils and teachers. The interviews performed in the study can be categorized as qualitativeinterviews, and in addition we recorded and took notes during the interviews and transcribed thematerial.The study shows the importance of a good learning environment when it comes to working withinformation seeking processes, that the instructor?s role is of outmost importance and that the pupilsfundamental knowledge of information seeking processes and their information literacy are keysuccess factors when it comes to project work linked to ICT to be productive.

The purpose of this paper is to evaluate the work situation for temporary workers within the field of journalism. During the past decade, influential external forces such as commercialization, new technologies and increased competition have brought great changes within the industry. As a result, employers value flexibility of manpower, not least to reduce cost, where the flexible employee is usually leased by the media company from a manpower company. Today it is a normal practice with manpower companies and this way of hourly paid form of employment. Although the temporary worker can sometimes benefit from this kind of employment, there are also significant setbacks like job insecurity.

AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

This report describes the results of the project "Concept development of jet engine inspection plugs" carried out in the spring of 2008. The work was done at the department of product definition at the company Volvo Aero in Trollhättan. The objective of the work was to develop concepts for a "Volvo-unique" inspection plug. The work is part of Volvo Aero's focus on proprietary (self-developed) technologies. Inspection plugs can be found on virtually all aircraft engines and gas turbines.

The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.

ABSTRACT Title (English): New technologies, same needs? A qualitative research of media usage in two generations, in the light of modern uses and gratifications research Title (original): Ny teknik, samma behov? En kvalitativ undersökning av två generationers mediebruk i ljuset av den moderna bruks- och belöningsforskningen Language: Swedish  Author: Frida Ivansson Tutor: Sven Ross Course: Media and Communication Studies, Bachelor's Thesis.  Period: Spring term 2013 University: Department of Journalism, Media and Communication (JMK) atStockholm University Purpose/Aim: The purpose of this paper is to, in the light of todays uses and gratification research, highlight the differences in media use in adolescents and adults. I focus on the informants' television viewing and I compare this cross-generational, and in relation to other media use. Material/Method: The method I used in this thesis is qualitative interviews. My choice fell on this method because I believe it to be the most suitable for obtaining the data needed.

AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.

Detta examensarbete genomfördes på ABB Power Technologies AB i Ludvika. ABB vill överbrygga gapet mellan industri och informationsteknologi för att få de båda delarna att arbeta integrerat. ABB kallar detta koncept för Industrial IT (IIT). Ett krav från koncernledningen är att alla produkter ska vara certifierade enligt nivå 0, som är det första steget i IIT: s certifieringsprocess. Målet var att utföra en kravspecifikation på ett system som ska kunna leverera certifierad produktinformation enligt IIT-standard.

Beroende på i vilken miljö man har tänkt att använda trådlös kommunikation behöver man hitta en modulationsteknik som passar under rådande förhållanden. I början på 1980-talet utvecklade den Amerikanska militären en modulationsteknik som kallas för Shaped BPSK (SBPSK) avsedd att tillämpas i kommunikationslänkar med satelliter. Vidareutveckling av SBPSK ledde sedan fram till en förbättrad variant kallad Shaped O?set QPSK (SOQPSK). På senare år har denna modulationsteknik börjat användas i civila tillämpningar och vidareutvecklats ytterligare för att ge den än bättre prestanda.

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.
