Advancements in web technology such as the integration of operating platforms, the application of mobile applets and connectivity with databases into an encompassing web environment has promoted the development of complex web-based systems for enterprise computing. In this integration the inherent security flaws and associated problems of these technological advancements are also brought together under this web environment. These flaws, when exploited, could lead to system compromises of various kinds including stealing of security sensitive information, system take-over fabrication of fake electronic documents and illegal alteration to web sites contents. Therefore, the successful, prompt and appropriate responses of these complex web-based systems to security threats and breaches, such as in the cases of document tampering and misrepresentation from illegal users, are imperative in promoting the user's willingness and confidence when interacting with these systems. Accordingly, this has become one of the major concerns in development, management and operation of web-based systems. This thesis also studies the authentication of dynamic web contents through the application of a one-time digital signature. To this effect, relevant concepts and possible approaches have been discussed. Authentication and verification of dynamic contents, efficiently in the web environment, is suggested as a separate research area and as a direction for future work. / Master of Science (Honours) Computing

<p><strong>Bakgrund:</strong> För att vara kostnadseffektiv och utveckla nya bilmodeller i snabb takt använder sig bilföretag av produktplattformar. En produktplattform är ingen fysisk produkt utan varieras med olika komponenter beroende på vilka delar på bilmodellerna som skall vara unika respektive vilka delar som skall vara gemensamma. Nackdelar med flera gemensamma komponenter är att slutprodukterna blir identiska i flera avseenden, vilket försvårar varumärkets arbete med att göra produkterna unika och skilja de från konkurrenternas. En konflikt uppstår således mellan produktplattformens strävan efter gemensamma komponenter och varumärkets arbete med att göra produkten unik.</p><p><strong>Syfte:</strong> Syftet med uppsatsen är att utifrån de gjorda fallstudierna på bilmodellerna Volvo XC60 respektive Land Rover Freelander 2 som producerats på en gemensam produktplattform analysera och jämföra varumärkenas och bilmodellernas benägenhet att förmedla vad som är unikt i samband med en reklamkampanj.</p><p><strong>Genomförande:</strong> Uppsatsen är genomförd med en kvalitativ ansats, där intervjuer har genomförts. Den empiriska studien är uppbyggd av två deskriptiva fallstudier och jämförelser har gjorts mellan fallen för att se skillnader.</p><p><strong>Resultat:</strong> Uppsatsen har kommit fram till att varumärket är av stort värde för företag eftersom två identiska produkter producerade på en gemensam produktplattform kan säljas som två unika produkter. Varumärket möjliggör nyttjande av produktplattformar på grund av sin strävan efter att ta fram det unika med produkten. Vid nyttjande av produktplattformar är det viktigt att varumärket är konsekvent och kommunicerar det som är unikt med produkten snarare än det som produkten har gemensamt med andra produkter. Uppsatsen har visat på att attribut av stor betydelse för att kommunicera ett konsekvent budskap.</p> / <p><strong>Background:</strong> In order to minimise costs and develop new car models in a timely manner, the car industry uses product platforms. A product platform is not a physical product, but a range of components that can be combined in various ways depending on specific individual product requirements. The disadvantage with using several common components is that the final products can be identical in several aspects, which complicates the brand’s goal of making the product unique and distinct from competitors. Conflict arises between the product platform’s ambition to use common components and the brand’s ambition to make the product unique.</p><p><strong>Aim:</strong> The aim of this master thesis, based on two case studies about the Volvo XC60 and Land Rover Freelander 2, is to analyze and compare the brands and the car models’ ability to mediate the uniqueness in a Swedish marketing campaign, despite the common components at the EUCD-plattform.</p><p><strong>Completion:</strong> The master thesis has been carried out with a qualitative approach, whereby interviews have been performed. The empirical study is built on two descriptive case studies and a comparison has been made between the cases.</p><p><strong>Result:</strong> The thesis has reached the conclusion that a brand is of great importance to a company since two identical products produced on a common platform can be sold as two unique products. The brand makes it possible to use a product platform due to the brand’s ambition to make a product unique. It is important when using a product platform for the brand to be consistent and communicate what is unique about the product rather than what the product has in common with other products. The master thesis has shown that attributes are important in order to communicate a consistent message.</p>

<p>Business has seen tremendous growth through internationalization over the last several decades.  As  one  of  the  strategies  for  companies  to  internationalize,  acquisition  has since then been a well-studied subject. Various steps have to be gone through in order to  acquire  a  company.  Afterwards,  companies  need  to  take  different  measures  to ensure  the  success  of  the  acquisition.  Culture  is  usually  considered  as  the  most important  aspect  which  determines  post-acquisition  success.  The  purpose  of  this master dissertation is to thus investigate company’s internationalization via acquisition regarding    the    pre-acquisition    decision-making    and    post-acquisition    cultural management. The  theoretical  framework  consists  of  literature  of  pre-acquisition  decision-making process and post-acquisition culture management. These theories are put together in an analytical  model  where  possible  connections  are  intended  to  achieve.  It  will  also  be used as a foundation in gathering and analyzing the empirical data.   In  a  qualitative  approach,  the  empirical  data  was  gathered  through  semi-structured interview with the president of Getinge International Group. These findings were also complemented with secondary data such as corporate websites, documents and various scientific articles. The findings of the study show that planning, evaluating, negotiating, making the deal and    integration    are    the    five    essential    steps    concerning    the    process    of internationalization  through  acquisition.  The  authors  find  out  that  identifying  of acquisition  candidates  is  not  necessarily  a  part  of  pre-acquisition  as  the  theory  may suggest.  The  distinction  between  bolt-on  and  platform  acquisition  is  of  critical importance to determine the different criteria and procedure certain company is going to take. This proves to be much more practical, where theoretical support has not been fully established. Both national and corporate cultures are of crucial importance for the success of company’s post-acquisition culture management. According to the finding of this research, two factors seem to link pre and post acquisition process; one is the planning of how future organization is managed; the other is the appropriate choice of managing director.</p>

<p>Software verification is an important part of software development and themost practical way to do this today is through dynamic testing. This reportexplains concepts connected to verification and testing and also presents thetesting-framework Trassel developed during the writing of this report.Constructing domain specific languages and tools by using an existinglanguage as a starting ground can be a good strategy for solving certainproblems, this was tried with Trassel where the description-language forwriting test-cases was written as a DSL using Python as the host-language.</p>

<p>This thesis serves as an introduction to anyone that has an interest in artificial intelligence games and has experience in programming or anyone who knows nothing of computer games but wants to learn about it. The first part will present a brief introduction to AI, then it will give an introduction to games and game programming for someone that has little knowledge about games. This part includes game programming terminology, different game genres and a little history of games. Then there is an introduction of a couple of common techniques used in game AI. The main contribution of this dissertation is in the second part where three techniques that never were properly implemented before 3D games took over the market are introduced and it is explained how they would be done if they were to live up to today’s standards and demands. These are: line of sight, image recognition and pathfinding. These three techniques are used in today’s 3D games so if a 2D game were to be released today the demands on the AI would be much higher then they were ten years ago when 2D games stagnated. The last part is an evaluation of the three discussed topics.</p>

<p>This paper describes our game engine written in C++, using the DirectX libraries for graphics, sound and input. Since the engine is written using DirectX, an introduction to this system is given. The report gives a description of the structure of the game and the game kernel. Following this is a description of the graphics engine and its core components. The main focus of the engine is on the physics and how it is used in the game to simulate reality. Input is discussed briefly, with examples to show how it relates to the physics engine. Implementation of audio in the game engine is not described, but a general description of how sound is used in games is given. A theory for the basics of how artificial intelligence can be used in the engine is presented. The system for the architecture of the levels is described as is its connection to the graphics engine. The last section of the report is an evaluation and suggestions for what to do in the future. A user manual for the level editor is included as an appendix.</p>

<p>During the last year Tieto has been interested in evaluating the potential of a newly developed technology called Rich Ajax Platform (RAP). The RAP technology allows the developer to write Java code and deploy it on the web as a Rich Internet Application (RIA)with similar look and feel as a regular application ran in for example Microsoft Windows. The biggest benefit with a RIA is that it offers similar features to stand-alone applications but these features are deployed via a web server i.e. no installation at the client side is needed.</p><p>To evaluate this technique a Scrum handler prototype was developed using the RAP. Secondly, a comparison with another similar technique called Google Web Toolkit had been made. The Scrum process is an agile development method which is based on small iterations.The purpose of this study was to create a functional prototype in order to evaluate and demonstrate the RAP technology.</p><p>The result of the evaluation is that RAP is a strong competitor for developing Web 2.0 applications. Most of the concerns regarding RAP depend on the fact that it is a new technology and is still under development. Since Tieto in Karlstad currently develops RCPapplications, the RAP technology is a logical successor since the developers do not have to learn a new technology.</p>

Innovating is essential to sustained industrial growth and profitability. But experience amply demonstrates how difficult innovation is, especially for large companies. The synthesis of valued offerings by aligning customer needs with technology possibilities lies at the heart of innovation. System architects working at the strategic level are ideally positioned, as a consequence of their experience and training, to play a key and even a leadership role in enabling, energizing, and leading this synthesis. The scope of the architecting effort must include the process architecture of the entire value chain as well as the more conventional product architecture to address all potential wellsprings of innovation. This paper outlines an architecture-centric approach to innovation, based on the concept of the system platform architecture. / Center for Innovation in Product Development, MIT

The requirements of modern e-learning techniques change. Aspects such as community interaction, flexibility, pervasive learning and increasing mobility in communication habits become more important. To meet thesechallenges e-learning platforms must provide support on mobile learning. Most approaches try to adopt centralized and static elearning mechanisms to mobile devices. However, often technically it is not possible for all kinds of devices to be connected to a central server. Therefore we introduce an application of a mobile e-learning network which operates totally decentralized with the help of an underlying ad hoc network architecture. Furthermore the concept of ad hoc messaging network (AMNET) is used as basis system architecture for our approach to implement a platform for pervasive mobile elearning.
