In this paper, we explore the idea that 5G will permit the use of multiple waveforms, with each service employing a waveform that is best suited for it. We look at a 5G machinetype communication (MTC) scenario consisting of clustered user equipment employing device-to-device (D2D) communication, such as a smart factory with inter-communicating machinery. The overhead associated with synchronisi...

Interaction plays an important role to the success of distance learning. As most distance learning environments utilize mainly asynchronous ComputerMediated Communication (CMC) systems, interaction research that focuses on synchronous CMC is largely ignored. This study scrutinize the patterns of learnerlearner interaction in a distance-learning environment. Student interactions in synchronous a...

The synchron...

Digital electronic systems typically use synchronous clocks and primarily assume fixed duration of their operations to simplify the design process. Time elastic systems can be constructed either by replacing the clock with communication handshakes (asynchronous version) or by augmenting the clock with a synchronous version of a handshake (synchronous version). Time elastic systems can tolerate ...

The paper is concerned with the timing analysis of a class digital systems we call mixed asynchronous{synchronous systems. In such a system, each computation module is either synchronous (i.e. clocked) or asynchronous (i.e. selftimed). The communication between modules is assumed to be selftimed for all modules. We introduce a graph model called MASS for describing the timing behaviour of such ...

This paper describes a novel communication scheme, which is guaranteed to be free of synchronization failures, amongst multiple synchronous and asynchronous modules operating independently. In this scheme, communication between every pair of modules is done through an asynchronous FIFO channel; communication between a module and the FIFO is done using a request/acknowledge handshaking. Synchron...

This report introduces a hybrid asynchronous, distributed audio/video group conferencing system. One of the chief benefits of Internet communication systems is that they allow communicators to write messages when they need to, and read messages when they can. Researchers, developers, and lay citizens are increasingly familiar with one of the benefits of e-mail and online text conferencing syste...
