<p>During the fall of 2008 a prototype of an educational multiplayer role-playing game called World of Wisdom (WoW) was developed as part of the specialization project TDT4570. WoW focuses on using knowledge for progressing through the game. The goal of this thesis was to design and develop a user-interface for teachers, that could be used to generate new content for WoW. In this thesis we described the design and implementation of such a user-interface called the WoW World Editor. The World Editor supports generating new maps, creatures, objects and questions for World of Wisdom. By making it easier to create the worlds, the course staff can focus on creating the knowledge for the game. For the students to be able to interact with the course staff while playing the game, we suggest a seperate client for the course staff. This client will then have additional functions that can be used to aid the students with problem, and to get valuable feedback from the players.</p>

<p>Nowadays the computer science is extremely important in business; thanks to it you can automate tasks, streamline processes and obtain information. The best resource for the new companies is the information. I mean, today the information is very necessary with the new technologies. Employers who are responsible to decide in their companies, have begun to understand that the information helps their business and also can be one of the best critical factors that can show us if the company work is successfully or not. (1) In recent years organizations have recognized the importance of managing key resources such as the working hours and the raw materials. ERP applications are often used to standardize business processes and unify data; the importance of that software in the companies is growing every day. Although we also can say that in some cases the ERP software doesn´t solve some business problems because there are processes that aren´t standard or common. Moreover, if we would create a module for our company it has to be usable .The usability is very important because that and the automation will help to increase the performance of coordinators. This project is a study of a particular case of a telecommunications company in which it has found a problem with the production process; In This Project we will be able to solve each problem that will appear in various stages of construction our module. These steps include: a study about if there are problems in the selected area of business, whether buying or building a new module, heuristic techniques and methods to improve the usability, quality of build module using polls, usability guidelines, use case... The results have improved the production of the company and the system provides the necessary information to the coordinators but the coordinators want further improvement. The study of the usability helps users to be ready to use the software correctly.</p>

<p>Mobility of people and their interactions with devices and services that every day become more pervasive in our life is a valuable challenge for system engineers. Locate friends, retrieve multimedia informations from physicals objects, have medical assistance remotely is going to be a commodity for a more and more wide part of the population, including elderly people. In this scenario have an easy way for discovering and communicating with third party services and resources that we encounter in our every day life is going to make the difference between an enjoyable user experience or a frustrating ones that quickly leads to the abandon of a system. Building on the work done in the past about resources discovery and management I study a solution for user-centered interactions with resources and services dynamically discovered and used by the user in nomadic environments. The solution designed make use of embedded devices, addressing the problem encountered in the research from both end-user and developer point of views. The solution proposal make a full use of the service oriented architecture (SOA) concepts focusing on the goal of achieving the most natural human interaction with devices that the user discover on his way, keeping at the same time the framework architecture lightweight and easily extendible by third-party developers, as the SOA paradigm requires. Accessibility and extensibility are achieved on the end-user side by deploying software needed for the personal device (UbiNode) on most common smartphones and providing a easily understable Graphical User Interface; on the developer side by creating a pluggable framework based on xml and Eclipse eRCP runtimes for a fast development of multiple user interface that fits the constrains of the device in which are them deployed in. Work done consists in design and implementation of several platform components and development of prototypes that takes profit from the overall architecture. Developed modules have been deployed end tested on handled devices. UbiCollab provides a solution platform for ubiquitous collaboration scenarios and this thesis has been carried out as a contribution to it.

<p>This report covers the research, design and prototype implementation of a social application for mobile ad-hoc networks, InstantSocial. The main goals of this project has been to look at this exciting field and examine how the European scientific collaborative project MUSIC can be used to develop such an application. The project has been conducted using a Design Science approach. First the field of interest, existing similar applications and technology was examined to get a good view of the current state-of-the-art and choose a suitable prototype application. Then the design of the application was constructed, emphasizing the important features outlined in the project goals. Finally a prototype was developed and tested as a means to prove the correctness and applicability of the design. The results of the project was somewhat divided. Although the developed prototype had limited functionality, mostly because of the current limitations of the used framework, the tests that were performed where positive. Not all of the requirements of the system was successfully implemented, but this was due to limited time available or limitations in the currently available version of the framework rather than a shortage of the design. We conclude that the presented design and approach to context-adaptation is very plausible as a way in which the MUSIC project can be used to develop social application for mobile ad-hoc networks, but that much more work and testing is required before such an application can be fully realized.</p>

<p>The goal for this master thesis is finding trends and behaviors in a highly available database cluster using InfiniBand and RDMA. This will be used to optimize configuration of the segment size in such systems. To find these trends and behaviors, a mockup model has been developed. The model consists of a simple DBMS that uses only the main memory for storing data and a checkpoint method to repair nodes after a node failure. During a repair, the model simulates use of InfiniBand and RDMA during checkpointing. To simulate clients connecting to and using the database, the model includes write operations on the database and measures how many write operations it can process per second. During a repair in a database cluster, one node will flush all of its data to a new node. This is done in small batches, just like in a checkpoint. In this model, it is simulated by a checkpoint module continuously simulating flushing data from one node to another. When the checkpoint is flushing a small part of the database fragment, the model uses Copy on Write to prevent lockout for the transactions. When a node fails the system is repaired by a second node which takes over as fast as possible. The second node must process transactions while transferring all of its data to a spare node. To achieve fast repair time, the system should transfer as big segments as possible. The problem with big segments is that it takes a long time to perform Copy on Write on them. With the mockup model, the repair time is measured, how many write operations are being performed per second and CPU usage depending on the segment size and number of clients using the database. This will give a good indication of what segment size is preferable. The results from the thesis show that there are huge advantages by using state-of-the-art technology such as InfiniBand and RDMA for repair in highly available database clusters. This technology and optimal configuration improves the availability and this thesis gives an indication that the segment size should not be more than 1 % of the database size. With use of InfiniBand and RDMA using this configuration and physical repair, the availability reaches class 9.</p>

<p>This project continues the work started in our depth study project in the fall of 2004, develop- ing a framework for mobile collaborative applications on mobile phones utilizing Personal Area Networks (PANs). This paper describes central, theoretical concepts connected to the Peer-to-Peer (P2P) comput- ing, the Mobile Ad Hoc NETworks (MANETs) and the Computer Supported Cooperative Work (CSCW) domains, focusing on "Same-Place-Same-Time" collaboration. We argue how the spread of PAN technology and mobile phones enable for a broad range of new collaborative applications supporting both collocated work and spontaneous interaction. Updated information about relevant technologies and related projects are discussed and evaluated. The requirements for the Peer2Me framework are presented and updated along with a revised and improved design. The design and the requirements are a product of an explorative development effort to develop the next generation of the Peer2Me framework using Java 2 Micro Edition and the Java APIs for Bluetooth wireless technology (JABWT). The Peer2Me framework is then tested on actual developers in a workshop arranged in May 2005. Data gathered from this workshop is used to illustrate the benefits of using a framework like Peer2Me for developing mobile collaborative applications. In addition to the actual Peer2Me framework implementation along with its Bluetooth network module, example applications are designed, implemented and tested in order to verify the suit- ability of the Peer2Me framework in the problem domain. These applications illustrate different kinds of aspects of the Peer2Me framework and the domain of mobile collaborative applications. The tests of these applications are done through enactment of the usage scenarios from which the applications were derived. The main results of this project are the technical products comprised of the Peer2Me framework, the Bluetooth Network module and the example Peer2Me applications, as well as the empirical data supporting the advantages of Peer2Me and the evaluations upon the suitability of the applied technologies.</p>

The main results of the report show that the use of animation gives a better understanding for the movement of individual points in the plots, before and after removal.</p>

<p>Denne oppgaven presenterer et rammeverk for representasjon av og resonnering med temporale data i CBR-systemet TrollCreek. Slik funksjonalitet vil forbedre TrollCreek’s ytelse innenfor prediksjonsproblemer, det vil si: Kunne prediktere hva som vil skje i en ny problemsituasjon basert på sammenligninger med lagrede problemsituasjoner. Representasjonen er basert på å legge til en eller flere tidslinjer til et case. Resonneringsmekanismen abstraherer disse tidslinjene inn i en enkelt tidslinje, og sammenligner deretter denne tidslinjen med andre abstraherte tidslinjer i case-basen. I denne oppgaven har vi implementert en enkel ikke-kunnskapsintensiv metode for denne abstraksjonsoppgaven og vi har brukt metoder for sekvenssammenligning for å sammenligne tidslinjene. Oppgaven inneholder også et eksempel av rammeverket i bruk. Eksempelet er av en ”proof-of-concept”-type, og involverer et imagniært domene.</p>

<p>Multiarch is a mechanism for packages supporting multiple architectures to be installed at the same time on the same machine in the same operating system. This paper shows a sample implementation of one way do do this on a UNIX-like system using the dpkg package manager. It shows the needed changes to both packages and the package manager itself.</p>
