In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.

The thesis hears content-error in relation to agreements closed by electronic means. The purpose of the thesis is to elucidate how the rules in 32 §(1) AvtL apply to agreements closed by such means and to evaluate its suitability. The elucidation is done on the basis of, the rules? adequacy in relation to their objectives in collaboration with a comparative view on a selection of international legal framework under private law, such as DCFR, UNCITRAL Model Law, UNIDROIT Principles and CISG.Since Sweden lack a specific regulation for electronically closed agreements, all modern closing methods will be evaluated from the dated outlook of the Swedish Contract Act. In relation to entirely automated processes which results in the closing of an agreement, particular difficulty arise in correlation with prerequisites, which requires a human stance.

This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.

Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..

During spring 2001 we have been involved with our bachelor thesis at Doberman Digital Agency, an Internet related webdesign company. We have focused our work on the registration process via digital medias such as the Internet. During our workprocess we have been conducting a number of studies and analyses of workrelated materials. Ethnographical methods such as structured interviews and participant observations were primarily used in our work. We also widely used brainstorming in our designprocess.

The last couple of years the use of mobile devices such as mobile phones and PDAs has increased tremendously. Most of the these devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

The purpose of this report is to outline the development of a dynamic Microsoft Silverlight application, which will be able to present products and be administered in a simple manner. The project has been carried out at Incordia AB, a company that specializes in e-commerce, situated in Helsingborg, Sweden. Although the Silverlight application is customized for a particular site, forMicro AB (an ongoing project at Incordia), the template and the classes that are used to manage information, are developed so that they can be used in future projects for Incordia AB..

During the years of development in the 60s and 70s the need for new housing in Sweden arose. Sweden was going to be the most modern country in the world. This period has later been called ?the time of the big programmes?. One of the parts in this building of a welfare society was a large policy of building politics with few counterparts in history.

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

Smakbas ? Gourmet Grön är en webbplats som ska kommunicera den gröna maten och marknadsföra Gourmet Gröns smakbaser. Webbplatsen innehåller information och bakgrund om smakbaserna, samt hur man jobbar med dem. Det finns även en lite annorlunda receptbank där besökaren kan titta på recept.

Game balance can be considerd complex - there are many factors that play a role in the perception of balance. This thesis examines complexity, game theory and intution in an effort to disconver more about the perception of balance. The findings are that tactical and strategical choices that are presented for a player need to be interesting, not to complex and not to obvious. The importance lies in the estimation of the result that the player does when making a choice..

Dagen samhälle är sårbarare än man ibland kan ana. Överbelastningsattacker är attacker mot ett specifikt nätverk, och syftet är att göra dess tjänster otillgängliga för legitima användare. Detta är något som sker varje dag mot företag runtom i världen, och inte minst i Sverige. Media har på senare tid uppmärksammat problemet sedan det blivit allt vanligare och vanligare bland företagen. Syftet med detta arbete är dels att få bättre förståelse om överbelastningsattacker är något som prioriteras eller inte, men även att få företagen uppmärksammade på vilka olika skydd som finns att tillgå mot överbelastningsattacker, samt att vi vill få företagen att verkligen tänka på vilka hot som finns där ute. Vårt mål med denna uppsats är att ta reda på vilka befintliga skydd företag i Sverige använder sig utav för tillfället samt vilka skydd de kan och bör använda sig utav. För att nå detta mål har vi genomfört kvalitativa intervjuer med företag som bedriver en stor del av sin försäljning, eller tillhandahållande av tjänster, över Internet. Detta har gjort att vi kommit fram till att företagen visserligen visst har skydd mot överbelastningsattacker och använder sig utav dem, men bör också se till vilka andra skydd som finns tillgängliga för dem och kan fungera bättre för just dem. Det finns som sagt bra skydd mot överbelastningsattacker, men det gäller att veta hur de fungerar och att använda dem på rätt sätt för att kunna utnyttja dem ordentligt. Vi tror, och hoppas, att detta arbete kommer att kunna hjälpa företagen i framtiden att lättare kunna stå emot överbelastningsattacker, och det är våran förhoppning att denna uppsats kommer att komma till nytta och tjäna sitt syfte..

Sammanfattning Fel i programvara (buggar) kostar ofantliga summor varje år. I detta arbete presenteras en metod där programexekveringsmiljön utan vare sig programmerarens eller användarens inblandning utförligt kan rapportera och dölja effekterna av en avsevärd andel buggar. Genom att kompilatorn eller tolken tillåter att en och samma procedur implementeras hur många gånger som helst införs ett helt automatiskt stöd för N-Version Programming (NVP) omedelbart i programspråket. Tekniken gör programvaran feltolerant och blir ett komplement till kostsam och ofta bristfällig testning. En tolk utvecklades för ett programspråk som tillåter multipla definitioner av procedurer. Därmed har det inbyggt stöd för feltolerans genom redundans på procedurnivå. Ett experiment genomfördes där nio programmerare oberoende av varandra implementerade 12 utförligt specificerade procedurer.

The aim of this Master?s thesis is to examine and present the programmes and activities of school library centres in order to see what functions (purposes) they can fulfil in a municipality and also if and how they can contribute to school library development. In order to fulfil my purpose I have made qualitative interviews with five librarians from school library centres. The theoretical framework is primarily based on David Loertscher?s.
