Power reduction is one of the main reasons for designing asynchronous circuits. Asynchronous circuits are inherently capable of having low power consumption. In this paper, we introduce five methods to achieve even lower power consumption. We have applied these methods to some sample circuits and the experimental results show that power reduction of 20% to 41% is obtainable.

This paper focuses on the impact of an asynchronous online discussion forum on the development of students’ ability in and attitudes toward writing in English. Two groups of third-year students (N = 60) majoring in English were assigned to two treatment and control groups, each receiving different types of feedback. Students in the treatment group were required to participate ...

in different projects the speed of different machinery can be estimated using manufacturer's handbooks and a number of modification factors to consider the environmental effects, type of the project and status of site management. since the statuses of different factors of the domestic projects are totally different from those of the international projects, there is a wide discrepancy betwe...

A review is made of the most important decisions in the design of asynchronous systems to support the preparation of business decision meetings. These decisions are illustrated with the choices made for the development of SISCO, a system of this type. The presentation considers issues in the discussion model, the group memory, the communication and visualization mechanisms, and the development ...

Given my current state of knowledge, and a desirable state of knowledge, how do I get from one to the other? It is possible in principle to reach the desirable state of knowledge, i.e., does it make sense at all to start trying to obtain the desirable state? If I know it is impossible to obtain, there is no use trying. But even if I know that it is possible in principle, is there a way to appro...

rotating machinery is the most common machinery in industry. the root of the faults in rotating machinery is often faulty rolling element bearings. this paper presents a technique using optimized artificial neural network by the bees algorithm for automated diagnosis of localized faults in rolling element bearings. the inputs of this technique are a number of features (maximum likelihood estima...
