Uses and benefits of information and communication technologies in distributed learning systems
1999
Masteroppgave i informasjons- og kommunikasjonsteknologi 1999 - Høgskolen i Agder, Grimstad Purpose and Methods. The paper is a presentation of my post graduate thesis at HiA. The focus of this study is Akademiet, a distributed learning system developed by Telenor Kompetanse in Grimstad, Norway. Akademiet is a web application developed for use by Telenor employees and clients who wish to take courses facilitated by the Internet. The increasing dissemination of networked computers, especially via the Internet, enables and accelerates changes in our educational system. Many reforms sought in education are exemplified and realized through this new distributed learning situation. We have gained…
A study of possible use of Radio Frequency Identification(RFID) in Abu Dhabi Sewerage Directorate
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad This report describes the possible use of RFID in a business case such as the Sewerage Directorate at Abu Dhabi Municipality & Town Planning Department. The prototype phase is developed using the ethnographic study which is called Contextual Design Methodology. RFID is not a new technology, but a technology that now widely increases its marked share by large companies recently looking at the potential of RFID implementations. It will still take several years to see if this newly found interest will lead into a RFID success story. RFID is set to replacec barcodes that are much used for pricing and/or …
Integrated communication solution for oil and gas safety systems
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad The telecommunication system on today’s oil installation consist of a number of different communication systems such as UHF radio (Ultra High Frequency), VHF radio (Very High Frequency), PABX (Private Automatic Branch eXchange), and PA (Public Address and Alarm). These communication systems have their own control panels. In addition these systems use various communication technologies for transportation of voice and data. The operators have to deal with each of these control panels to operate these systems under normal and critical situations. In critical situations it can be crucial for the operator…
Skalerbar og QoS-bevisst arkitektur for innholdsbasert distribusjon av store mengder data over WAN
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad Vi ser stadig at data som overføres på Internett øker, både i form av antall og størrelse. Ettersom uønskede pakker er blitt et økende problem, er det utviklet systemer som ruter pakkene kun til ønskelig mottaker ved hjelp av pakkens innhold. Innholdsbaserte distribusjonssystemer blir ofte brukt i disse tilfellene. Utviklingen av slike systemer er ofte beregnet for distribusjon av små data pakker hvor rask overføring er et krav. Ettersom størrelsen på data som overføres øker i takt med den teknologiske utviklingen, settes det større krav til et innholdsbasert distribusjonssystem. Data kan eksempelvis…
Component-based development on the Windows DNA platform : post-graduate thesis in information and communication technology
2000
Masteroppgave i informasjons- og kommunikasjonsteknologi 2000 - Høgskolen i Agder, Grimstad This report deals with key areas of software development in a distributed environment. Distributed computing systems are becoming increasingly more popular, and the demands for functionality are growing accordingly. With distributed systems being used for so many different purposes, and with so many people depending on it to do their jobs, these systems must be stable and robust to continuously serve the users. If the system fails, for example caused by network problems or by application crash, it can in the worst case paralyze the organization. With this as a starting point, we have been looking at …
Providing location transparent services with Java technologies : testing support of Open Distributed Processing transport transparencies in JINI, web…
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad This thesis tests the presence of Open Distributed Processing (ODP) distribution transparencies in Jini, Jxta and Web Services. The thesis presents an introduction to each technology, a description of the test criteria developed, selection of prototype applications, test execution and presentation of the results. Main focus is on testing support of transparencies at the application developer and system designer level. The work has shown that all technologies support transparence types that have to do with the location of a service; location transparency and migration transparency. But when it comes t…
Wireless Personal Relationship Manager for future mobile devices
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad I nær fremtid vil mobiltelefoner bli kraftigere og mer anvendbare for programmer som før var forbeholdt datamaskiner. Nå som det allerede er kommet mobiltelefoner med innebygget WLAN er det stor sannsynlighet for at denne funksjonaliteten vil bli standard innen noen år. Dette åpner flere dører når det gjelder applikasjoner som kan kjøres på mobile terminaler og mulighetene man har. Denne masteroppgavene utforsker mulighetene ved å lage en trådløs kontaktinformasjonsutveksler for slike mobile terminaler. Det er lagt størst vekt på tankr rundt konseptet og hvordan det kan utvikles. Oppgaven tar for seg…
Using J2EE technologies for implementation of ActorFrame based UML 2.0 models
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Ericsson has developed a prototype of a Java framework called ActorFrame, for development and execution of services. The services will be deployed in networks where current Telecommunication and Internet has merged into an open service oriented network. The services are modeled using UML 2.0 concepts for concurrent state machines communicating asynchronously through message passing. ActorFrame has been used in development of prototype services deployed in real networks as part of the AVANTEL research project. The background for this thesis study is that Ericsson wants to move ActorFrame to a J2EE tec…
Using Jini and JavaSpaces with Ericsson NorARC's technologies for service creation : a new way of adapting to dynamic environments
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad Ericsson NorARC (Norwegian Applied Research Center) is developing architectures and frameworks for advanced telecom and Internet systems and services. The current technologies are JavaFrame, ActorFrame and ServiceFrame, which enable rapid development and system dependability. Jini is a technology for making dynamic, robust and self-healing distributed systems. It can be used with JavaSpaces technology, which is a distributed shared memory technology that provides loosely coupled communication in time, space and destination. In this thesis, we evaluate if Jini, JavaSpaces and frameworks building on th…
Peer-to-peer Programming with Wireless Devices
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad Peer-to-Peer programming (P2P) has in recent years become a widely explored research area. With the evolution of wireless technology such as mobile phones, the idea to bring these two technologies together gives a new dimension to P2P communication, collaboration and resource sharing. This master thesis explores the domain of Mobile Peer-to-Peer networking and proposes a Peer-to-Peer System with Wireless Devices. The system is based on an open, protocol-based P2P platform called JXTA. It allows any connected device on the network ranging from sensors and cell phones to personal computers and servers …
