The study aims to investigate student?s attitudes and experiences of information retrieval on the Internet, as tools for learning. I have been interested of their own views about their own knowledge and experience in the subject, information seeking on the Internet. The focus is on what they perceive as problematic, what skills they consider they have and what needs they have in terms of teaching. Data were collected via questionnaires.

Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.

In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Kunskapen om TV- och datorspelmissbruk bland ungdomar är idag väldigt begränsad. Stillasittande/fysisk inaktivitet, som TV- och datorspel ofta innebär och som kan innebära negativa konsekvenser, blir allt vanligare. En semistrukturerad intervjustudie har genomförts på sju män i åldersgruppen 17-29 år i syfte att undersöka drivkrafterna bakom mäns spelbeteende i tonåren. Dessutom har information om spelmissbruk bland ungdomar inhämtats av fyra yrkesverksamma inom spelområdet. Detta samt kopplingar mellan TV- och datorspel och spel om pengar har gjorts p g a bristen på forskning om TV- och datorspel.

In 2009 The National Land Survey of Sweden, Lantmäteriet, commenced a project intended to provide a new digital elevation model (DEM) of Sweden. The method chosen for the project was airborne laser scanning (ALS). In addition to information about the land surface the project will also provide information about the forest, this as a by-product. This data can be used to estimate forest variables such as height and volume. The estimates are often more reliable than what is standard today. This study is based on interviews with employees and members of the forest owner association Södra in southern Sweden.

This Bachelor Thesis in the area of Computer Science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool. Advan-tages and disadvantages of this way of working are discussed. Our studies show that distance work is a good complement for personal meet-ings between designer and co-developer.

This project measures the upper bound of exposure time for laser reflection detection in the software DotDetector. Via measurement of the exposure time for which distortion happens in a room lit with everyday light we conclude that the upper bound for exposure times are 100 milliseconds. This value does not change as long as the lighting in the room is the same. As future work this project proposes variable upper bounds depending on secondary lighting in the room. Also we propose automating the colour masking of the detection algorithm..

To challenge the competition within the construction business there are requirements ineffectiveness and use of operating computer based programs and work-methods. Thecomputer based programs are continuously improved and can at some point be the start of anew work-method. The work-method of tomorrow can be Building Information Modeling(BIM).This Master of Science Thesis gives an understanding in what BIM is and what therequirements for Sweco Theorells are in a future BIM-use as a consulting-firm. Theunderstanding is presented through a study of theory within the subject. The way of thinkingand acting among different disciplines and individuals within the building process isexplained through an interview study.The term BIM is regularly used.

AbstractThe purpose of this study is to examine how children interact with each other and what social positions they assume when using the learning pad. The social positions reffered to is the Owner, the Participant and the Spectator, defined by Ljung Djärf (2004). According to Ljung Djärf (2004), the Owner is defined as the one in control of the mouse and keyboard. The Owner is expected to be in charge of what is happening on the screen. The Participant is typically found on a chair near the computer.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation. The possibility to protect oneself against attacks from the outside becomes increasingly difficult.

Användandet av trådlösa nätverk ökar med rask takt och blir allt vanligare. Enligt en artikel i Computer Sweden kommer de trådlösa näten att ha 20 miljoner användare om 4 år. Analysföretaget Gartner Group har nyligen gjort en undersökning bland företag, vars syfte var att ta reda på hur stort intresset var för WLAN. Resultatet visade att 50% av företagen funderar på att köpa och installera WLAN-lösningar (Planet Wireless september 2001). Syftet med detta arbete var att beskriva hur den inbyggda krypteringsfunktionen WEP som för Wired Equivalent Privacy fungerar och hur säker den är, dvs hur lätt man kan knäcka krypteringen. Följande frågeställningar har besvarats genom litteraturstudier och ett praktiskt försök: Hur är trådlösa nät uppbyggda? Hur fungerar den inbyggda krypteringen WEP och hur säker är den? Vad kan man göra förutom att använda sig av WEP för att skydda sig mot avlyssning/intrång? Det praktiska försöket bestod av att knäcka WEP-krypterade filer med hjälp av programmet WEPCrack.

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

Användandet, eller frånvaron, av öppen källkodsprogramvaror inom offentlig sektor är något som på senare tid har diskuterats flitigt både i artiklar och i internetanslutna diskussionsforum. Den offentliga sektorns behov av investeringar i nya IT-system kommer dessutom att öka i och med realiseringen av Statskontorets vision om 24-timmarsmyndigheten. Detta examensarbete undersöker hur välbekant begreppet öppen källkod är, vilka attityder som finns mot begreppet och hur stor utbredningen av öppen källkodsprogramvaror är hos Sveriges kommuner. Av resultatet framkommer att 60 % av alla IT-chefer och motsvarande i kommunerna känner till begreppet väl, att 80 % av alla tillfrågade upplever öppen källkod som något positivt och att drygt 30 % av alla kommuner redan använder någon form av programvara baserad på öppen källkod. De viktigaste fördelarna med öppen källkodsprogramvaror är den låga kostnaden, tillgången till all källkod och att man snabbt kan få del av andras förbättringar. I flera länder i både Europa och Asien, såväl som Sydamerika förekommer rekommendationer, eller åtminstone diskussioner, om hur öppen källkod bäst kan användas för att stödja den offentliga sektorn i respektive länder. För att användningen av öppen källkodsprogramvaror skall ta fart även bland Sveriges kommuner krävs fler leverantörer av support och andra kringtjänster, ytterligare förbättring av säkerheten hos programvarorna, samt mer information om vad begreppet faktiskt innebär..
