A comparison with synchronous circuits suggests four opportunities for the application of asynchronous circuits: high performance, low power, improved noise and electromagnetic compatibility (EMC) properties, and a natural match with heterogeneous system timing. In this overview article each opportunity is reviewed in some detail, illustrated by examples, compared with synchronous alternatives,...

Collective Intelligence (CI) is the ability of a group to exhibit greater intelligence than its individual members. Expressed by the common saying that “two minds are better than one,” CI has been a topic of interest for social psychology and the information sciences. Computer mediation adds a new element in the form of distributed networks and group support systems. These facilitate highly org...

R(2) effect-size measures are presented to assess variance accounted for in mediation models. The measures offer a means to evaluate both component paths and the overall mediated effect in mediation models. Statistical simulation results indicate acceptable bias across varying parameter and sample-size combinations. The measures are applied to a real-world example using data from a team-based h...

Fashion technology is an expanding field, yet the question of how technology can be considered fashionable remains unexplored. According to fashion theories, mediation plays a fundamental role in transforming clothing items into fashionable garments. In this study, we explored how fashion films, as one of the most important fashion media in the industry today, could make wearable design concept...

Ternary optical computer (TOC) has become a research hotspot in the field because of advantages such as inherent parallelism, numerous trits, low power consumption, extendibility, bitwise allocability and dynamical reconfigurability. Meanwhile, its performance evaluation attracts more attentions from potential users researchers. To model computing ecology accurately, this paper first builds thr...

This paper introduces intersubjectivity as a concept playing a crucial role in collaborative tasks, even when performed between partners at a distance. Two 5th grade classes from two European countries (Italy and Greece), collaborated in writing fairytales inspired by philosophically relevant issues. The software supporting the task is an asynchronous virtual environment. Videos recorded in the...

Computer architecture researchers evaluate key areas such as pipelining, organization, instruction issue, branching, and exception handling when considering asynchronous and synchronous design and implementation trade-offs. Asynchronous or clockless designs are considered as an alternative to conventional synchronous digital system design. The major advantages of asynchronous are low power cons...

We present a unified technique for timing verification and performance analysis of complex asynchronous systems designed with implicit timing assumptions. Our method models interacting controllers and datapath elements using timing constraint graphs. Performance metrics and timing constraints to be verified are formulated as time separations between appropriate events. Separations between all r...

When designing asynchronous systems, the problems of hazards becomes an important issue. This paper deals with the hazard-free implementation of asynchronous logic in a look-up table based FPGA. First, the definitions of hazards and techniques to deal with them in gate-level asynchronous circuits are surveyed. Then the look-up table (LUT) model and its associated timing properties are presented...
