TL;DR: This paper tries to describe a behavioral logical operations language by using Statecharts, a data structure that is used to represent by a Boolean function in a logical operation.
Abstract: Statechart has been utilized as a visual formalism for the modeling of complex systems. It illuminates the features on describing properties of causality, concurrency and synchronization. In this paper, we try to describe a behavioral logical operations language by using Statecharts. The logical operation is a data structure that is used to represent by a Boolean function. This paper used them to analyze the models which are modeled by using Statecharts. Their formalism provides a concept of propositional logic for presenting control strategy. Finally, an example of level crossing traffic control systems is examined successfully.

TL;DR: The authors propose a family of tree machines called generalized compressed tree machines, which may, in general, be viewed as a derivative of the complete binary tree networks.
Abstract: Parallel machines interconnecting up to thousands of processors have been proposed and recently built. One of the earliest and the most prominent one is a complete binary tree machine. The authors propose a family of tree machines called generalized compressed tree machines. Generalized compressed tree machines may, in general, be viewed as a derivative of the complete binary tree networks. >

TL;DR: In this article , the authors analyze a physically motivated mesh-connected computer model, assuming that a word of information takes a given area and that it takes unit time and unit energy to move a word unit distance.
Abstract: We analyze a physically motivated fine-grained mesh-connected computer model, assuming that a word of information takes a fixed area and that it takes unit time and unit energy to move a word unit distance. This is a representation of computing on a chip with myriad tiny processors arranged as a mesh. While most mesh algorithms assume all processors are active at all times, we give algorithms that have only a few processors on at any one time, which reduces the power required. We apply this approach to basic problems involving images, showing that there can be dramatic reductions in the peak power with only small, if any, changes in the time required. We also show that these algorithms give a more efficient way to utilize power when more power is available.

TL;DR: The basis design is enriched with a novel multiple redundancy fault-tolerance scheme so that the sorter meets high reliability specifications and is a completely modular system having three levels of modularity, all exhibiting high regularity throughout.
