Challenges and Frontiers of Computer Graphics : A Vision for an Applied Research Agenda

Future Research directions for IT-based, visual applications are presented as visions developed from evolutionary, technological trends and presented based on observations from different views (system,application, user). These visions, for - Human Media Technology -Augmented Reality - Digital Storytelling - Integrated, interactive broadcasting - Multimedia workspaces - Interactive appliances are then discussed in some detail, giving all together a rich picture on what we can expect to be reality in the market place by 2010

Mobile Visualization: Challenges and Solution Concepts

Relatively cheap and widely available wireless data communication services are available to the mass-market. Within the coverage of the cellular network used,the vision of information access for `everyone, anytime, anywhere' has become reality. A Global Information Visualization environment can be imagined where the vision of `All information at your fingertip' is reality. In this environment, every information, data, or tool available on any computer connected to the global network is directly accessible to the user. However because of the low bandwidth of wireless networks and the limited resources of mobile hardware, the handling of highly interactive distributed multimedia applications faces severe problems. The objective of `Mobile Visualization' is to provide effective solutions to these problems. This paper discusses the relevant aspects of systems and data models for Mobile Visualization and tries to provide an integrative view on the field based on the vision of Global Informa..

Karyotypic analyses and morphological comments on the endemic and endangered Brazilian painted tree rat Callistomys pictus (Rodentia, Echimyidae)

The genus Callistomys belongs to the rodent family Echimyidae, subfamily Echimyinae, and its only living representative is Callistomys pictus, a rare and vulnerable endemic species of the state of Bahia, Brazil. Callistomys has been previously classified as Nelomys, Loncheres, Isothrix and Echimys. In this paper we present the karyotype of Callistomys pictus, including CBG and GTG-banding patterns and silver staining of the nucleolus organizer regions (Ag-NORs). Comments on Callistomys pictus morphological traits and a compilation of Echimyinae chromosomal data are also included. Our analyses revealed that Callistomys can be recognized both by its distintinctive morphology and by its karyotype
