In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

Outsourcing är en företeelse som, trots att den egentligen är relativt gammal, fått sitt genombrott under 1990-talet. En Application Service Provider (ASP) är en ny typ av företag som bygger vidare på konceptet för outsourcing. Genom att anlita en ASP kan ett företag/organisation få tillgång till applikationer utan att behöva köpa licenser eller hårdvara.Det finns flera anledningar till att ett företag/organisation väljer att använda sig av ASP. Genom att intervjua företag/organisationer som använder ASP har en undersökning gjorts om vilka anledningar, så kallade faktorer, som varit avgörande då beslutet att anlita en ASP togs. Utgångspunkten för undersökningen har varit anledningar som ASP-marknaden och dess analytiker menar är orsaker till att ASP väljs.

Denna rapport syftar till att besvara frågan om det är nödvändigt att göra omfördelningar av befintliga IT-resurser för att erhålla största möjliga nytta med application service provider-modellen (ASP-modellen). Rapporten besvarar även frågan om hur IT-avdelningens fokus hos en ASP-kund påverkats av det nya arbetssättet. De svar som presenteras i rapporten visar på att en omfördelning av IT-resurserna kan vara en bidragande orsak till att införandet av ASP anses lyckat. Vidare påvisar rapporten att efter att ASP införts försvinner vanligtvis en del av de tekniska arbetsuppgifterna och undersökningen som gjorts pekar mot att IT-avdelningen får ansvar för att ta fram krav för vidare samarbete med ASPn. Ansvaret yttrar sig genom att någon på företaget får ansvaret för att kontrollera om leverantören håller de servicenivåer som kontraktet fastställer.

This thesis is a part of the DySCAS (Dynamically Self-Configuring Automotive System)project which has the overall purpose of creating a middleware for the electronics in an automotive environment. The thesis has been made with collaboration with ENEA AB who is a member of the DySCAS project. ENEA AB has developed a demonstration platform to test the fundamental ideas which the DySCAS project is built on.The purpose of this thesis was to design and implement a GPS application to be added to the demonstration platform. This was done by adding a GPS receiver to the original DySCAS demonstration platform and designing and implementing an application to be able to extract the information from it. The resulting application is able to present cur- rent position and absolute time to the DySCAS networks as services to be used by other applications or by the network it self.

With the digital revolution within video games, the need for Digital Rights Management (DRM) has increased significantly, alongside with the increasing problem of copyright pirates. To counter pirates, DRM was created to prevent illegal copying of software, this to ensure that the Distributors received an income for their work. DRM has, since the start of its use, been getting, a lot of bad criticism from the users of the software protected by DRM. The main function of this paper is to describe the creation and development of DRM by analysis of the vision of different groups on this phenomenon. The main questions are as follows, is it possible to define the very reason for why DRM was created and if so, can its development through time be defined too? What differences in opinions are there when it comes to DRM, counting the two major groups of creators, sellers, distributors (referred to as distributors) versus individual users (referred to as consumers)? In what way will the research results suggest that the future DRM will develop?The development has gone from solving puzzles in a handbook to start the game each time the user wants to play, to serial numbers that is needed during the installation of the game.

The EU-funded project European Cultural Heritage Online (ECHO) aims to integrateresources from various domains within the field of cultural heritage, and make them availableon the Internet. To accomplish this integration it is necessary to describe the various resourcesin a way that will achieve cross-domain interoperability. This description of digital resourcesis commonly referred to as metadata. The most well known and used metadata standard is theDublin Core Metadata Element Set, a general standard developed for the purpose ofdescribing all types of digital resources. Since the mid-1990's a large number of specializedstandards have emerged in different communities, for example IMDI, designed for detaileddescription of language resources.This thesis aims to examine the possibility of combining a general and a specialized metadatastandard to achieve cross-domain interoperability and at the same time provide a sufficientlydetailed description of language resources for researchers within the field of linguistics.

Allt sedan datorer började användas som en resurs i företag har mindre företag sett de höga kostnaderna dessa fört med sig. I slutet av 1990-talet skapas en modell som möjliggör att hyra program från en Application Service Provider, ASP. Med ASP-modellen följer ett flertal förväntningar och fördelar om vad modellen kan tillföra i framförallt mindre företag. De ska till exempel till lägre kostnader få tillgång till program som kan öka deras konkurrensförmåga. Denna rapports fråga är om modellen lever upp till dessa förväntningar hos kunderna.Vid intervjuer som genomfördes med fem olika företag framkom bland annat att ASP-modellen kan möjliggöra ett minskat behov av egen IT-personal och att internt kunna ge användarsupport.

This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.

Requirements management is an important part of the software development process. The success of a project may depend on how this is handled. Even though several research studies indicates that more attention should be paid on non-functional requirements, the primary focus in practical projects still regards identifying functional requirements. Especially the prioritization of the non-functional requirements has been proven to be of great importance for the success of a project.This report investigates basics in agile requirements management involving opinions from experts from a software development company. This is done with help of existing literature and interviews with key actors involved in prioritization at the company.

This degree project is made for Cervera in Norrköping and Linköping. The task was to create a professional interactive homepage for the company where the company's range of products can be presented. Besides a homepage aimed towards potential customers, an online Internet-application where the company's employees can update, erase, and create posts that are stored in the database was created. The main programming languages have been PHP and HTML in combination with databases in MySQL. The final result was a functional, professional and informative homepage with a simple and pedagogical application for the employees.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.

This thesis treats the normative power of the European Union and its affect on Macedonia. The main purpose has been to look closer with the use of the application of Ian Manners theory of normative power on the Macedonian case. The focus will be to answer the following questions: Does the European Union act as a normative power in relation to Macedonia, if so, how are these values diffused? Has there been any effect of the spreading of these values? Based on six interviews and the available material of European Union strategies for the Macedonian membership I have attempted to understand to what extent the European Union?s normative power has had an influence in Macedonia. The result of my analysis is confirmation of the European Union as a normative power in Macedonia and the understanding of the methods of application..
