A variety of field trials have been conducted at NJIT in the past few years to demonstrate the utility of a Delphilike approach to promoting asynchronous class wide collaboration. These utilized the Social Decision Support System (SDSS) originally developed as a Computer Mediated Communication (CMC) system for large group decision support. This paper provides an overview of these studies and th...

Perfect failure detectors can correctly decide whether a computer is crashed. However, it is impossible to implement a perfect failure detector in purely asynchronous systems. We show how to enforce perfect failure detection in timed asynchronous systems with hardware watchdogs. The two main system model assumptions are (1) each computer can measure time intervals with a known maximum error, an...

Through a series of projects carried out by the Computer–Human Interaction and COllaboration (CHICO) group University Castilla-La Mancha, some proposals are presented to improve current e-Learning systems making use different paradigms human-computer interaction. Synchronous asynchronous collaborative systems, ubiquitous computing, augmented reality can learning environments. The artificial int...

The implementation and evaluation of asynchronous search techniques can be done in any programming language allowing a distributed programming. Nevertheless, for the study of such techniques and for their evaluation, it is easier and more efficient to implement the techniques under certain distributed environments, which offer various facilities, such as NetLogo and are open-source. This articl...

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...

Due to the non-stationarity of EEG signals, online training and adaptation is essential to EEG based brain-computer interface (BCI) systems. Asynchronous BCI offers more natural human-machine interaction, but it is a great challenge to train and adapt an asynchronous BCI online because the user’s control intention and timing are usually unknown. This paper proposes a novel motor imagery based a...

We show undecidability of hereditary history preserving bisimilarity for finite asynchronous transition systems by a reduction from the halting problem of deterministic 2-counter machines. To make the proof more transparent we introduce an intermediate problem of checking domino bisimilarity for origin constrained tiling systems. First we reduce the halting problem of deterministic 2-counter ma...

The increasing needs for power consumption of computing machines is getting a worrying factor for the emerging embedded systems. Asynchronous computer architecture reduces the power consumption of the systems. They are built around using emerging concept of clock less systems. Asynchronous computing systems have demonstrated a full scaled computational performance to fulfill the emerging needs ...
