Developing interactive 3D graphics for mobile Java applications is a reality. Recently, the Mobile 3D Graphics (M3G) API was proposed to provide an efficient 3D graphics environment suitable for the J2ME platform. However, new services and applications using interactive 3D graphics, which have already achieved reasonable standards on the desktop, do not yet(More)
Developing interactive 3D graphics for mobile Java applications is now a reality. Recently, the Mobile 3D Graphics (M3G) API (also known as JSR-184) was proposed to provide an efficient 3D graphics environment suitable for the J2ME platform. However, new services and applications using interactive 3D graphics, which have already achieved reasonable(More)
This paper presents an analysis of the performance impact of two generic group communication APIs, namely Hedera and jGCS. The analysis was carried out in a four-node cluster by comparing the performance of different configurations of two well-known group communication middleware systems (i.e., JGroups and Spread), under different message sizes, both in(More)
This paper presents an evaluation of the performance impact of two generic group communication APIs, namely Hedera and jGCS, over three well-known group communication systems, namely JGroups, Spread and Appia. The evaluation compared the performance of different configurations of the three group communication systems in a local clustered environment, under(More)
An interactive computer-based training tool for using in Orthodontics is aimed at students and experienced professionals who need to predict orthodontic treatment outcomes. Usually, treatment planning and the choice of a proper appliance model are based exclusively on clinician expertise, and most orthodontists work on a trial and error basis, estimating an(More)
