In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...

correct estimation of water inflow into underground excavations can decrease safety risks and associated costs. researchers have proposed different methods to asses this value. it has been proved that water transmissivity of a rock joint is a function of factors, such as normal stress, joint roughness and its size and water pressure therefore, a laboratory setup was proposed to quantitatively m...

the objective of this paper is to develop an artificial neural network (ann) model which can beused to predict temperature rise due to climate change in regional scale. in the present work data recorded overyears 1985-2008 have been used at training and testing steps for ann model. the multilayer perceptron(mlp) network architecture is used for this purpose. three applied optimization methods a...

Objective(s): Stress is a physiological response that can disrupt body elements homeostasis and lead to neurophysiological abnormality. This study has been investigated the serum and hippocampus Mg2+, Zn2+, Fe2+/3+ and Ca2+ level changes in two times after MgO NPs and ZnO NPs single injection following restraint stress in the male rat. Methods: Animals were divided into two main groups that eac...

Drought stress in plants, the change (increase or decrease) in the production of plant proteins. Proteomics in recent years one of the most powerful tools that help us to study the changes in protein In order to investigate the proteome of wheat leaves in response to terminal drought, two genotypes susceptible and resistant wheat genotypes were evaluated under irrigated (non-stress) and rain-fe...

Following an acute stressor, pre-adolescent rats exhibit a protracted hormonal response compared to adults, while after repeated exposure to the same stressor (i.e., homotypic stress) prepubertal males fail to habituate like adults. Though the neurobehavioral implications of these changes are unknown, studying pubertal shifts in stress reactivity may help elucidate the mechanisms that underlie ...

Estimation of the stress distribution in ferromagnetic components is very important for evaluating the working status of mechanical equipment and implementing preventive maintenance. Eddy current testing technology is a promising method in this field because of its advantages of safety, no need of coupling agent, etc. In order to reduce the cost of eddy current stress measurement system, and ob...

objective: social anxiety disorder (sad) is defined as a constant fear of being embarrassed or negatively evaluated in social situations or while doing activities in the presence of others. several studies have examined the role of certain variables that might predict response to treatment and may affect treatment outcome. the purpose of this study was to identify predictive variables of change...

Long-term stress accumulation influenced by coseismic changes and postseismic viscoelastic relaxation is considered critical to triggering giant earthquakes. Nevertheless, how the increase interrupted aftershocks it influences megaseismic cycle remain enigmatic. In this study, based on Mohr–Coulomb failure criterion at nucleated segments of 2008 great Sichuan earthquake, variation associated wi...
