In this paper, a real-time denoising filter based on modelling of stable hybrid models is presented. Thehybrid models are composed of the shearlet filter and the adaptive Wiener filter in different forms.The optimization of various models is accomplished by the genetic algorithm. Next, regarding thesignificant relationship between Optimal models and input images, changing the structure of Optim...

Background and Aim: Among the failures of a disaster, the disruption of the critical infrastructure of the community causes the most damage to society. Therefore, the ability of critical infrastructure such as hospitals to anticipate, absorb, adapt or rapidly recover from a devastating event is essential. The purpose of this study is to design a self-adaptive model for resilient hospital system...

A desired dynamic behavior of constrained manipulators can be achieved by means of impedance control and various implementations of fixed controllers have been proposed. In this paper, and adaptive implementation is presented as an alternative to reduce the design sensitivity due to manipulator mismatch. The adaptive controller globally achieves the impedance objective for the nonlinear dynamic...

conclusions these findings suggest that exposure to tc-99m could induce a radio-adaptive response against the exposure of tl-201. background low dose radiation will induce adaptation and following exposure to an adaptive dose, the cells are more resistance to following challenging doses. this phenomenon is known as radio-adaptive response. the aim of this study was to investigate the percentage...

the adaptive response (ar) is a phenomenon by which cells exposure to sublethal doses of dna-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (ct), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (cr). the adaptive response (ar) induced by radiation in human lymphocyte...
