Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

A strong brand can help a company to be easier to recognize and be remembered by their customers. Part of branding is to create a visual appearance which is called a graphic profile and contains information on for instance a logo, colours or typography.The objective of this thesis was to create a graphic profile for Stjørdal Tannhelsesenter that could serve as a base for a brand work in the future. It was important to analyze how the clinic wants to be perceived and how it is perceived today. The methods used to carry out this study were questionnaires, researches and a focus group.The work resulted in the generation of a graphic profile that included a new logo, colours, decorative elements, fonts, templates for stationery, business card / badge, imagery, and examples of some publications.According to the test which was made to examine the results of the project showed that I was successful and that the new design meets all the requests from the previous questionnaires..

Since criminality started to rise steeply in most western welfare states following the second world war the relationship between welfare support and criminality has been debated. For a period of time thought to be an effective preventive measure against crime welfare support has since from time to time come to be seen by some as ineffective and in some cases even as a contributing factor to the rise in crime. It remains a contested issue as new theories, such as social support theory, which is employed here, attempt to contribute to the understanding of what effects general welfare has on overall crime levels. As a connection which is relatively well-researched in the USA, altough still not yet fully understood, this study strives toward a better understanding by testing the relationship in a swedish context. The relationship might not function in the same way considering that the US is a fundamentally different welfare-regime than Sweden, liberal and social-democratic respectively.Untangling the relationship is attempted by employing a multivariate regressionanalysis on a crosssectional dataset consisting of data from 2012 covering 247 of Swedens total of 290 municipalities.

An industry in distress was the breeding ground for a noted pricing strategy, labeled name-your-price. The industry was the music industry and the pricing strategy bears reminiscence of how medieval buskers earned their living during the dark ages; by letting the customers decide how much the good was worth, embodied by a thrown coin into a hat or similar collector. Translated into the contemporary corporate environment of today, where technical innovations provides access to the intellectual property for free, a few mighty economic actors have once again turned to the strategy were it all started; letting the customer set the price. The hat has been replaced by a box for your credit card number and the live music by a MP3 file, but the similarity is striking. The business model have been applied in other industries as well with various levels of success, thus the purpose of this thesis is to set up a framework for where the name-your-price strategy is applicable.

Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.

Examensarbetet handlar om en jämförelsestudie av beräkningseffektivitet med avseende på energi- och tidsförbrukning mellan grafikkort och processorer i persondatorer och PlayStation 3.Problemet studeras för att göra allmänheten uppmärksam på att det går att lösa en del av energiproblematiken med beräkningar genom att öka energieffektiviteten av beräkningsenheterna.Undersökningen har genomförts på ett explorativt sätt och studerar förhållandet mellan processorer, grafikkort och vilken som presterar bäst i vilket sammanhang. Prestandatest genomförs med molekylberäkningsprogrammet F@H och med filkomprimeringsprogrammet WinRAR. Testerna utförs på MultiCore- och SingleCorePCs och PS3s av olika karaktär. I vissa test mäts effektförbrukning för att kunna räkna ut hur energieffektiva vissa system är.Resultatet visar tydligt hur den genomsnittliga effektförbrukningen och energieffektiviteten för olika testsystem skiljer sig vid belastning, viloläge och olika typer beräkningar..

The degree project has been implemented abroad in Brisbane, Australia. A literature study has beenperformed parallel to the practical work within the subject »Corporate identity through graphicaldesign«. In this study deeper research has been made concerning the establishment and manifestationof a corporate identity and its program. The knowledge given from this study has been put into practicethrough two larger projects.The first project was carried out at De Pasquale, advertising agency in Brisbane, where a corporateidentity program was designed for a new company. The company is a fitness centre, called KnockoutFitness, which specializes in different types of boxing training sessions such as Boxing, Thai Bow andBoxercise but also Aqua aerobics.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

För att informationsöverföring över publika nät ska kunna utföras på ett säkert sätt krävs identifiering, signering och kryptering, vilka är grundstenarna i en elektronisk signatur. Dessa delar i kombination ger oss bl.a. säker e-handel. Som plattform för detta ligger PKI (Public Key Infrastructure), vilket är samlingsnamnet för lösningar där man med hjälp av en speciell krypteringsteknologi skapar system för identifiering, kryptering och integritetskontroll (Halvarsson & Morin, 2000). Systemen kan användas för att till exempel skapa elektroniska signaturer för olika typer av avtal, säkra elektroniska transaktioner, identifiering av användare, säker e-post, och olika typer av säker kommunikation över publika nätverk.Tekniken lovordas till stor del, men även dess brister förs fram av kritikerna.

Consumers today leave a fragment of information when they pay with their debit and credit cards. The aim of our work is to investigate ways to design a concept of a system in which digitally stored information that today is fragmented among several different holders, can be assembled into a system and made available to consumers. In our study of how a system for financial flow of information should be designed, we intend to study the present situation and the attempts made to alter it into a more informative reality. We intend to investigate the flow of information when a consumer pays by card, and the possible solutions regarding the design and transportation of digital receipts. A majority of the information of our digital consumption is today handled digitally.

This study examined gray areas within professional ethics of a public library organization and investigated the relationship between the library as an organization and the librarian as an employee when it comes to support and opportunities to make exceptions to rules and regulations. This relationship is then related to workplace issues.Data were gathered via interviews with six librarians who were placed into two focus groups. Library organization documents that contain rules and regulations (guidelines) were examined. The presumption was that conformity between librarians? experiences and actions and the organization?s guidelines will tell us something about workplace conditions.

This essay is about persons who have had social assistance and the individual?s experiences of social assistance. The focus is on how the individual develops in a new life situation and if and how they are motivated to get out of it. The essay has an individual perspective where the relation between society and the individual is important. The result is based on four qualitative interviews with a hermeneutic perspective.

The purpose of this master?s thesis is to gain insights into students? usage and attitudes towards electronic articles and electronic books and how students feel about a change from print collections to digital collections at Växjö University Library. The main questions are: How do different groups of students use the library collections of electronic articles and electronic books? What factors influence the usage of the library collections of electronic articles and electronic books among students? What are the students? experiences of reading electronic books in comparison with reading print books? What would different groups of students think if the literature they need for their studies were purchased in electronic form instead of print? To answer the questions a user study was carried out at Växjö university library. A web survey was sent to students that had a library card and an email address registered at the library.

The number of elderly people has been steadily rising in Sweden for a long time and as a proportion of the population, the increase has been even greater. The population structure in the country means that in the not too distant future, there will be a sharp rise in demand for care and elderly accommodation.A tighter credit market as a consequence of new rules and regulations with a stricter capital and liquidity requirements combined with market turbulence, has made financing property developement more difficult and more expensive which has resulted in many companies using alternative sources of finance.DEmand for safe investments with low risk is high as the market is volatile and banks, pension funds, fund management and life insurance companies are looking for investments outside the stock market that can deliver a safe return in the longer term. There has also been a debate about whether institutional investors as the AP pension funds really should own properties directly.As properties for care and elderly accommodation are definable assets with predictable payment flows, long leases and often a local authority as tenant that would not risk cancelling payments, these would be highly appropriate for securitisation, i.e. to issue bonds or other tradable securities based on the cash flows from the assets.In other words, the securitisation of rent flows would offer the opportunity to create an attractive investment product of the type being demanded, well suited to institutional investor requirements, while at the same time, it can provide an attractive financing opportunity to meet the need for more care and elderly accommodation..

Bakgrund och problem: Efter införandet av IFRS 2 ska svenska börsbolag behandla aktierelaterade ersättningar som en kostnad i redovisningen. Då detta inte krävdes tidigare, medförde de nya reglerna diskussioner om vilka konsekvenserna skulle bli. Frågan är om kostnadsföringen av dessa ersättningar lett till att bolag utformat sina aktierelaterade incitamentsprogram annorlunda efter införandet av IFRS 2.Syfte: Att undersöka om införandet av IFRS 2 har påverkat svenska börsbolags utformning av aktierelaterade incitamentsprogram samt förklara orsaken till en eventuell förändring.Metod/Empiri: Information har samlats in via årsredovisningar från 42 svenska noterade bolag under en tidsperiod av tio år. Datamaterialet analyseras genom observationer och regressionsanalyser där isolering sker av påverkan från företagsspecifika faktorer.Slutsatser: Studien visar på att förekomsten av optionsprogram minskar under åren 2003 och 2005 samtidigt som antalet aktieprogram ökar. Förändringen sker samtidigt som införandeprocessen av IFRS 2 och stämmer överens med antagandet om att kostnadsföringen av aktierelaterade ersättningar ligger bakom förändringen.
