ODP Channel: an Open Mechanism for Supporting Media Flows in Distributed Environments
Today's distributed applications need to interoperate across diierent administrative domains, handle multiple types of media, and execute on diierent computer platforms with diierent processing and networking capabilities. This demand poses several challenges to the application designer. Issues such as interoperability, real-time communication, security and performance must be properly addresse...
متن کاملSupporting Continuous Media in Open Distributed Systems Architectures
Recent developments in high-speed networks and highperformance workstations have led to the emergence of a new class of applications termed distributed multimedia applications. However, the range of distributed systems architectures currently being proposed to support open systems integration were largely conceived prior to these developments. Initial work directed towards the introduction of m...
متن کاملMechanism of secondary currents in open channel flows
This paper describes the conditions for initiation and maintenance of secondary currents in open channel flows. By analyzing the Reynolds equation in the wall-normal and wall-tangent directions, this study reveals that, like other types of vortices, the secondary currents are originated in the near-boundary region, and the magnitude (or strength) of secondary flow is proportional to the lateral...
متن کاملODP View on Quality of Service for Open Distributed Multimedia Environments
Quality of Service (QoS) requires standardization to achieve some consistency in terminology, models and mechanisms to operate successfully in an open distributed environment. This paper embraces this standardization effort and addresses the QoS issue from an ODP perspective. The objective of this paper is to relate the multimedia QoS concepts found in the literature and ISO-QoS framework to th...
متن کاملScaffolding: A way for supporting learners in e-learning environments
Introduction: One of the effective ways to help learners improve their learning in learning environments is scaffolding. Scaffolding can be defined as teachers, other learners and resources support of learner on tasks that can’t be done alone. Experts strongly demand scaffolding to be used to help learners on abstractive and complex issues. The aim of this study is to examine the scaffoldi...
