Computer-Supported Cooperative Work (CSCW) systems are often distinguished by the time and space proximity of their intended users. A four-quadrant graphic is often used to show the possible combinations: synchronous -co-located, synchronous -remote, asynchronous -co-located, asynchronous -remote. We argue that several dimensions other than time and space are critical to consider. In particular...
This paper presents two high-throughput, low-latency converters that can be used to convert synchronous communication protocol to asynchronous one and vice versa. These two hardware components have been designed to be used in Multi-Processor System on Chip respecting the GALS (Globally Asynchronous Locally Synchronous) paradigm and communicating by a fully asynchronous Network on Chip (NoC). Th...
We developed a Web-based education system called “Web-Com”. It supports synchronous and asynchronous learning. It consists of an interactive web browser and voice server. Web-Com provides a multi-layer drawable canvas on which the user can draw annotations. Each layer can be shared with other users in real-time via the Internet to enable synchronous learning. In conjunction with the voice serve...

The performance of linear multiuser receivers in terms of the Signal-to-Interference Ratio (SIR) achieved by the users has been analyzed in a synchronous CDMA system under random spreading sequences. In this paper, we extend these results to a symbol-asynchronous system and characterize the SIR for linear receivers | the Matched Filter receiver, the MMSE receiver and the Decorrelator. We rst an...
While affect plays a similar fundamental role in both, electronic and face-to-face negotiations, the expression of emotions in computer-mediated communication differs considerably from face-to-face settings. The aim of this experimental study is to analyze how the systematic use of emoticons – facilitated with software – affects negotiation behavior in alternative computermediated negotiation s...
Message-based communication is an increasingly common interaction mechanism used in concurrent and distributed systems where components interact with each other by sending and receiving messages. It is well-known that verification of systems that use asynchronous message-based communication with unbounded FIFO queues is undecidable even when the component behaviors are expressed using finite st...
This paper presents a formal system based on the notion of objects and asynchronous communication. Built on Milner's work on-calculus, the communication primitive of the formal system is purely asynchronous, which makes it unique among various concurrency formalisms. Computationally this results in a consistent reduction of Milner's calculus, while retaining the same expressive power. Seen sema...
Today’s workforce is expected to be highly educated and to continually improve skills and acquire new ones by engaging in lifelong learning. E-learning, here defined as learning and teaching online through network technologies, is arguably one of the most powerful responses to the growing need for education.1 Some researchers have expressed concern about the learning outcomes for e-learners, bu...
