We show in this paper how it is possible to reconstruct an image, in a very parallel way. using an asynchronous cellular array, with real-time performance. After introducing the image reconstruction problem, we present the main reconstruction techniques and the sequential algorithms. Then, we explain the manner to process these algorithms on a network. We describe this new integrated parallel a...

Finite field arithmetic operations, especially for the binary field GF(2 m ), have been widely used in the areas of data communication and network security applications such as errorcorrecting codes [1,2] and cryptosystems such as ECC(Elliptic Curve Cryptosystem) [3,4]. The finite field multiplication is the most frequently studied. This is because the timeconsuming operations such as exponenti...

Eficient multipath tracking i s a crucial requirement for high performance in asynchronous cellular CDMA. Despite the recent increased focus on use of array receivers at the base stations, the problem of time-delay estimation for individual paths has not been specifically addressed. In this contribution we propose simple and fast multipath tracking procedures in a nonstationary CDMA environment...

the need for clean groundwater resources to have sustainable development in a country is undoubted. due to the importance and high quality of karstic waters in supplying water in iran especially in shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest of tepal area, shahrood. for this purpose, integration of the results obtained from the metho...

In this article, a carbon nanotube (CNT) array-based system combined with a polymer thin film is proposed as an effective drug release device directly at cellular level. The polymeric film embedded in the CNT array is described and characterized in terms of release kinetics, while in vitro assays on PC12 cell line have been performed in order to assess the efficiency and functionality of the en...

We present a software environment for the efficient simulation of cellular processor arrays (CPAs). This software (APRON) is used to explore algorithms that are designed for massively parallel fine-grained processor arrays, topographic multilayer neural networks, vision chips with SIMD processor arrays, and related architectures. The software uses a highly optimised core combined with a flexibl...

A system which combines the descriptional power of symbolic representations with the parallel and distributed processing model of cellular automata and the speed and robustness of connectionist symbol processing is described. Following a cellular automata based approach , the aim of the system is to transform initial symbolic descriptions of patterns to corresponding object level descriptions i...

We propose in this paper a massively parallel machine dedicated to image synthesis by discrete ray tracing techniques. This machine is a four-stage pipeline, the last stage being a bidimensional cellular array with one cell per pixel. Two main phases describe its behaviour: • Loading into the cellular array of the objects of the scene to be displayed, after having been transformed into sets of ...
