The investigation of non-stationary wave phenomena in isotropic viscoelastic solids using analytical approaches is the aim of this paper.Concretely, the problem of a thin homogeneous disc subjected to radial pressure load nonzero on the part of its rim is solved.The external excitation is described by Youth Goggles the Heaviside function in time, s
Short-Term Hydrological Drought Forecasting Based on Different Nature-Inspired Optimization Algorithms Hybridized With Artificial Neural Networks
Hydrological drought forecasting plays a substantial role in water resources management.Hydrological drought highly affects the water allocation and hydropower generation.In this research, short term hydrological drought forecasted based on the hybridized of novel nature-inspired optimization algorithms borsa mini and Artificial Neural Networks (AN
Risk assessment of marine construction projects using Taguchi Loss Function
Today complicated EXTRA C 500 MG and risky environment makes risk assessment and identification one of the main steps of proper project management and realization of project objectives.Marine construction projects are key and strategic projects, and their specific nature adds to their importance.This study aimed to propose a method for risk assessm
Evolution of Lactase Persistence: Turbo-Charging Adaptation in Growth Under the Selective Pressure of Maternal Mortality?
The emergence of the capacity to digest milk in some populations represents a landmark in human evolution, linking genetic Birthday Card change with a component of niche construction, namely dairying.Alleles promoting continued activity of the enzyme lactase through the life-course (lactase persistence) evolved in several global regions within the
