As computer networks improve, more social and work interactions are carried out “virtually” by geographically separated group members. In this paper we discuss the design of a tool, PAVE, to support remote work interactions among colleagues in different time zones. PAVE extends a 2D graphical MOO and supports synchronous and asynchronous interactions. PAVE logs and indexes activities in the spa...

Designers of industrial datacom systems often ask, what is the most cost-effective implementation for multidropped, medium-speed, serial data communications? What data rates can be reliably achieved over what distance, and how? The design trade-off has always been less distance at a higher rate, or greater distance at a lower rate. So, the crucial question is: how far can you reliably transmit ...

This paper deals with the problem of deadlock detection in asynchronous messages communication systems. The considered system model covers unspecified receptions, not FIFO channels, and general resource (message) requests including, among others, AND, OR,

The technology in intelligent terminals enables communication from the process level to the SCS, substation, SCADA/EMS, and the network levels. Any function and parameter can be programmed and changed remotely. Automatic sequences can be included on bay and substation levels utilising the SCS. In addition, with serial communication, binary inputs, and user programming, it is possible to adapt f...

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...

This paper presents an optimized column fast Fourier transform (FFT) architecture, which utilizes bit-serial arithmetic and dynamic reconfiguration to achieve a complete overlap between computation and communication. As a result, for a clock rate of 40 MHz, the system can compute a 24-b precision 1K point complex FFT transform in 9.25 s, far surpassing the performance of any existing FFT systems.

In this paper we lay out the design time and space of component assembly in a visual builder, and propose concrete ways of also handling context components seamlessly. We present an environment that allows Java developers to test and evaluate JavaBeans components implementing the extensible runtime containment and services protocol. We enhanced the BeanBox from the Bean Development Kit (BDK) wi...

We deene a concurrent mobile system as one where independently executing components may migrate through some space during the course of the computation, and where the pattern of connectivity among the components changes as they move in and out of proximity. The deenition is general enough to encompass a system of mobile hosts moving in physical space as well as a system of migrating software ag...
