recent droughts and indiscriminate use of ground water for agriculture, is the main problems of the especially desert country.water crisis has gripped all of country plains, and due tothe reduction of surface water resources and successive droughts, illegal exploitation of ground water resources is increasing.the knowledge of the water balance plains can be helped in the water resources managem...

Ovarian tumors are formed either in the absence of Bam (bag-of-marbles) in germ-line cells or the overexpression of Dpp (decapentaplegic) in ovarian somatic cells. These tumor cells contain spectrosomes characteristic of ovarian germ-line stem cells and the immediate descendents called cystoblasts. We show that pole cells can successfully populate the gonad after transplantation to the dorsal m...

Introduction: Tooth extraction can result in loss of alveolar bone. The application biomaterials Bovine Amniotic Membrane (BAM) that containing growth factors and collagen is expected to play a role socket preservation. This study aimed observe the effect BAM on osteoblasts, osteocytes, histological preparate bone Sprague Dawley rats (SD). Methods: 16 male SD were used this group. extracted man...

Previous research has shown that Bidirectional Associative Memories (BAM), a special type of artificial neural network, can perform various types of associations that human beings are able to perform with little effort. However, considering a simple association problem, such as associating faces with names, iterative type BAM networks usually take hundreds and sometimes thousands of learning tr...

objective: reports of the prevalence of ptsd has been variable between 28-70% after the earthquake disaster in the city of bam, among children. several studies in adults have shown a high comorbidity of anxiety disorders as well. in this study we evaluated the frequency of ptsd and anxiety symptoms among adolescents in the period of 7-9 months after a large scale disaster (bam earthquake). meth...

The notion of best approximation mapping (BAM) with respect to a closed affine subspace in finite-dimensional spaces was introduced by Behling, Bello Cruz and Santos show the linear convergence block-wise circumcentered-reflection method. possesses two critical properties circumcenter for convergence. Because iteration sequence BAM linearly converges, is interesting its own right. In this paper...

Abstract: The global exponential stability is investigated for a class of reaction-diffusion Cohen-Grossberg-type BAM neural networks with time delays. By constructing suitable Lyapunov functional and using homeomorphism mapping, several sufficient conditions guaranteeing the existence, uniqueness and global exponential stability of reaction-diffusion Cohen-Grossberg-type BAM neural networks wi...

In this paper, we discuss parallel implementation of an artificial neural network for pattern d a t i o n , the Bidirectional Associative Memory(BAM). Transputer-based parallel architecture8 like hypercube, mesh and linear array are used to exploit the parallelism in BAM. A comparitive study of utilization and speedup for various architectures is made. Hypercube performs better in terms of util...

In this paper,the exponential passivity criteria for BAM neural networks with time-varying delays is studied.By constructing new Lyapunov-Krasovskii functional and dividing the delay interval into multiple segments,a novel sufficient condition is established to guarantee the exponential stability of the considered system.Finally,a numerical example is provided to illustrate the usefulness of th...

Interruption of monsoon rainfall by prolonged spells of sparse rainfall (break-monsoon) during the midmonsoon months of July and August over the plains of northern India (20°-29'N, 75O-85'E) has been investigated. When a tropical low-pressure system moves from the plains in a northerly direction toward the submontane region of the Himalaya, the monsoon trough of low pressure also moves from the...
