Analysis of the use of a workflow engine for OTRUM system software
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Workflow engines are attracting more and more attention. Applications based on workflow engine technology are currently developed and deployed by many companies, such as OTRUM Company. In this project, we focus on the analysis and development of an efficient workflow engine for interactive TV. The research project will realize workflow engine solutions based on three choices including commercial workflow engine, open source workflow engine, and a workflow engine implemented from scratch. In this project, we go through all mentioned solutions. In the literature, many proposed workflow engines are invo…
Stochastic Learning-Based Estimation Methods for Pattern Recognition and Its Application to Topic Detection and Tracking
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad Every Pattern Recognition (PR) problem involves a training and a testing phase. In the training phase, the system is presented with samples, using which the distribution (also called the classconditional distribution), of the features, is estimated. Traditional PR systems assume that the class-conditional distributions are stationary, and thus that they do not change with time. Recently Oommen and his co-authors have presented a strategy by which the parameters of a binomial/- multinomial distribution can be estimated when the distribution is non-stationary. In this thesis, we propose a selection…
Mutual Backup System
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad I de senere årene har det kommet nye teknologier for backup og behovet for sikkerhetskopiering er i økende vekst. Både privatbrukere og bedrifter har viktige data som må tas kopier av på en sikker måte og oppbevares på et sikret sted. De fleste bedrifter har gode nok ressurser til å lagre sine data via online backup eller andre løsninger som for eksempel SAN. Privatbrukere har ikke de samme lagringsbehovene, og derfor kan online backup være kostbart for lagring av små mengder data. Vår oppgave går ut på å forske på eksisterende løsninger for sikkerhetskopiering og teknologier som kan benyttes for å u…
A Generic Model of Project Management with Dynaplan smia
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad Projects are hard to be managed due to the reason of complexity, non -linear relationship and high dynamic. System dynamics has been proven a powerful and efficient way to manage projects. In this research, a generic system dynamics model applying to project management has been made. Through studying the model, the system behaviours have been analyzed and policies to deal with the problems of project management have been established. In addition, an object-oriented feature has been added into the model. The attempt is new to system dynamics modelling, and the outcome is satisfying since it makes …
A generic model of project management with Vensim
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad Large projects without good management will often cause cost and deadline overruns, missing the project scope and insufficient quality. The construction of the channel tunnel which link between England and France was budgeted at $7 billion, but it entered service in the second half of 1994 with a price tag of $13 billion. The Disneyland in Paris initially planned to cost $2.25 billion in the project, but finally cost $4 billion. Some projects are even never finished, typically software projects System dynamics has proven to be an effective methodology to explain the reasons of project failure and…
Process Improvement Solution for Mobile Platform Customer SW Development
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad Time to market is becoming an increasingly important topic in software industry. In this trend, handling customer change requests is of a paramount importance. In the current thesis, we investigate reducing the lead time of handling customer requests at EMP Grimstad. Problems were identified and an extensive solution that covers all the aspects of these problems are presented. An experience was conducted and the first results are promising.
Clustering with Terracotta
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad In today’s java community, modern enterprise application products have more constraints and requirements then ever. High availability, application scalability and also good performance are required, which means an application is needed to be deployed on multiple JVMs, in other words, it has to be clustered or distributed. It is essential for the application to scale out well, has better performance and less complexity during development of clustering. This master thesis focuses on clustering with Terracotta which is a JVM level clustering technique. First I start analyzing the complexity when an …
Accessible eGovernment services : developing a parental benefit calculator with improved usability
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad An online parental benefit calculator offered earlier by the Norwegian Labour and Welfare Organisation (NAV) gave only simple estimates on how long a mother or father could take the parental leave and did not support assessment of scenarios allowing for combination of the leave with a part-time job, the so-called “graded withdrawal”-scenarios. To work out such scenarios, the parents-to-be had either to get acquainted with the regulations and work out the various scenarios manually or contact the local social security office for assistance. We present a prototype of a new version of the parental benef…
Neighbor discovery and resource allocation for device-to-device communication
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 Device-to-Device (D2D) communication has attracted lots of attention as one of the most advanced wirelesscommunication technologies which allows access to services offered by nearby devices bypassing the BaseStation (BS). The potential advantages of this direct communication paradigm include high data rate, networkoffloading and range extension, as well as commercial proximity services and social networking. From the UserEquipments (UEs) and BS perspective, additional protocol overhead and discovery resource are required forD2D links. In such a context, neighbor discovery and resource allocation appro…
An AI for dominion based on Monte-Carlo methods
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 To the best of our knowledge there exists no Arti_cial Intelligence (AI)for Dominion which uses Monte Carlo methods, that is competitive on ahuman level. This thesis presents such an AI, and tests it against someof the top Dominion strategies available. Although in a limited testingenvironment, the results show that our AI is capable of competing withhuman players, while keeping processing time per move at an acceptablelevel for human players. Although the approach for our AI is built onprevious knowledge about Upper Con_dence Bounds (UCB) and UCBapplied to Trees (UCT), an approach for handling the st…
