During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

Denna undersökning syftar till att undersöka och utvärdera den agila projektmetodiken med inriktning på Scrum. Vattenfallsmetoden berörs även med avsikt att tjäna som kontrast till agil projektmetodik och Scrum. Att arbeta utefter en specifik projektmetod eller anamma ett agilt förhållningssätt kan bidra till att rätt produkt utvecklas och att undvika att projektet misslyckas. Undersökningen baseras på tre grundpelare; litteraturstudie, intervjuer och undersökning av befintliga studier. Dessa ligger till grund för de resultat som presenteras och diskuteras i uppsatsen med avsikt att kartlägga förekommande fenomen i projekt bedrivna efter en agil metod. I uppsatsen redogörs för och diskuteras resultatet av bedrivna intervjuer med personer i IT-branschen samt resultatet av befintliga studier utförda på bland annat Microsoft och Adobe Systems.

abstractThe aim of this essay is to try to convince the reader that relativism and postmodernism (the latter implying the former, but not the other way around) can be reasonable methods for the social sciences, rather than the irresponsible play of ?extremes? theories of this kind sometimes are made out to be.The intention is to do this by way of the later Wittgenstein, the philosophy of whom is the foundation for what is termed relativism and postmodernism in this essay (definitions of a kind that are here claimed to be missing from the discourse of the social sciences). The essay also contains an empirical presentation/analysis, displaying the Wittgensteinian theory through an aspect of the American Civil Rights movement of the 1950s and -60s..

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 you can get a complete instruction about how to build your own development system for the PIC-processor. This card will be used for laborations for the students at LITH-ITN. With this card you can send new assembler codes (new instructions) down to the microprocessor via the Serialport on your computer. Then the new instructions for the microprocessor will start to execute. We made a solder paste stencil at Campus Norrköping solder paste stencil laboratory.

Syftet med denna uppsats var att identifiera designprinciper vid migrering av stationära spel till Apples iPhone. Litteraturstudier, heuristisk utvärdering, enkätundersökning och djupintervjuer användes som metoder. Resultaten visade på att framför allt inmatningsmetoder, brist på feedback och skärmstorlek är problemområden i migrerade spel. Slutsatser inkluderar att spel aldrig bör migreras exakt som de stationära versionerna, nya inmatningsmetoder hos mobiltelefoner bör utnyttjas bättre och det bör övervägas om vissa spel överhuvudtaget bör migreras beroende på genre..

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.

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.

Background Svenska Spel is a regulated company run by the state and government, where CSR, community and social responsibility is in focus. The highly regulated Swedish gaming market has in recent years become more exposed to competition by foreign unregulated betting companies thru Internet.Problem discussion There are two views regarding CSR and how they are affecting competitive advantage and profitability. On one hand, it suggests that companies foremost shall focus profits and act in the best interest of the shareholders. On the other hand, it connects CSR to be a contributor to competitive advantage that increases the company?s profitability.Problem formulation Svenska Spel is competing with other betting companies who doesn´t act under the same conditions, betting companies that don´t have a responsibility to the state.

As a result of my fascination for nature I have chosen to study the possibilities to introduce natural environments on schoolyards. Too many schoolyards are lacking vegetation and many of them look like sterile asphalt deserts. The master thesis consists of two parts. The first part is based on literature studies and the second part in which findings from part one are put into practice. Five examples are presented; four schoolyards in Malmö; Kryddgårdsskolan, Kirsebergsskolan, Rörsjöskolan and Lindängeskolan and one in Kalmar; Åbyskolan. Malmö Naturskola has been working with the chosen areas on the schoolyards in Malmö.

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.
