Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.

En grafisk ritare i flygande system måste under dess utveckling verifieras för att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara identiska mot referensbilder genererade av en fungerande ritare så ställer det krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att automatisera den processen är i högsta grad intressant för att minska kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan uppstå, däribland ett sätt att utvinna eventuell transformation mellan två bilder..

This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The aim of the work was to compare two different pricelists with the actual output from a harvester. The results have also been compared with a volume estimate of standing trees done by the Swedish Forest Agency and the ?true? value registered by the Wood Measurement Association. The study confirms that the output calculated by the computer on the harvester is more reliable than the volume of standing trees estimated by Swedish Forest Agency. .

The main purpose of this thesis has been to investigate librarians opinions about the need for and possibility to use non-roman script in library catalogues. We have also investigated the routines of handling materials in non-roman scripts in two Swedish libraries. The investigation was made in the light of the recent shift in character set in the Swedish National Library Catalogue Libris. This change will enable use of multiple writing systems in the future.Our findings are that a multicultural society requires special consideration to the needs of citizens who speak other languages than the majority of the population. This becomes difficult when the languages spoken have a different writing system than the one used by the majority.

The project Design analysis and proposals of plastic screw caps in Australia was performed at Högskolan Dalarna incooperation with University of Western Sydney, Australia. The Swedish company Tetra Pak, in Lund, were assigner forthe project that was performed 2006-2007. The commission was to do a survey about the packages for non-carbonateddrinks in Australia. The bottles had to be plastic, able to open in one step and with focus on the caps.The project has result in design analysis and a new proposal of a plastic screw cap for the Australian market. Sixbottles were choosen and they were all testet on 20 consumers each with a Likert-scale test.

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

Kandidatarbetets syfte är att undersöka mötet mellan människa och medium genom att undersöka hur människor relaterar till och tolkar mötet med ett medium. Undersökningen tar sin utgångspunkt i flera tänkbara kunskapsfält, bland annat posthumanism, transhumanism, tolkningsvetenskap. Dessa kunskapsfält prövas sedan i en gestaltning för att avgöra om kunskapen är relevant i förhållande till vårt ärende..

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

The way we interact with computers will soon change dramatically. The input interfaces are becoming more and more intuitive and one of the latest technologies is a touch screen interface capable of dealing with multiple inputs simultaneously. The tools we use to communicate with the computer - such as the mouse and the keyboard, will slowly disappear and be replaced with tools more comfortable and more natural for the human being to use. The purpose of this project was to create a basic framework for future projects dealing with this interface, as well as creating some example programs. This report describes my work and my experiences with this new interface..

Background: IT-security is included in the concept of information security, which considers all the security of handling information within an organisation. Good IT-security is about finding the right level of measurement, however, it is hard to implemement new IT-solutions in an organisation, particularly within the health care field, where sensitive information are handled daily. Lately the Swedish government, together with county- and city council, understand the importance of IT and health care. Carelink, an organisation of interest, is working actively for the presumption of benefit by using IT within the health care field. During spring 2006 the Swedish government introduced a national IT-strategy.

Implementeringen av tredje generationens mobila nät (3G) har lett till att nya användningsområden skapats inom mobila tjänster. Bandbreddens ökade kapacitet gör det nu möjligt att skicka betydligt större mängder information än i tidigare mobila nät. Detta har även medfört att nya tjänster skapats för 3G-mobiltelefoner. Ett område under utveckling är mobil turistinformation. Mobila Guiden är en mobil turistapplikation som TelecomCity i Karlskrona tagit fram.

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..

This bachelor thesis looks at developers knowledge about web security both regarding their own view on their knowledge and their actual knowledge about vulnerabilities and how you mitigate against them. Web developers knowledge regarding web security are becoming more and more important as more applications and services moves to the web and more and more items become connected to the internet. We are doing this by conducting a survey among developers that are currently studying in the field or are working in the field to get a grip on how the knowledge is regarding the most common security concepts. What we saw was that the result varies between the different concepts and many lack much of the knowledge in web security that is getting increasingly more important to have..
