A system failure Fish probability analysis method of cohesive slope considering the spatial variability of undrained shear strength is proposed.In this method, the local averaging parameter of the random field of undrained shear strength on slip surface is introduced as an equivalent parameter.The statistical characters of the equivalent parameter
Abstract Background Heterotrichous ciliates are common members of microeukaryote communities which play important roles in both the transfer of material and the flow of energy in aquatic food webs.This group has been known for over two centuries Nut Butters due to their large body size and cosmopolitan distribution.Nevertheless, species identificat
Purpose.A goal of the work is development of 3D numerical model for a territorial risk assessment in a case of a terrorist attack with usage of a chemical agent.Methodology.To describe the process of chemical agent dispersion in the atmosphere, emitted in a case of a terrorist attack, the equation of mass transfer of an admixture in atmospheric air
In order to improve working accuracy of motor unit of mine cable winding car, aiming at problems of load disturbance and speed adjustment in the operation control of cable motor and reel motor, a cross-coupling control method for motor of mine cable winding car was proposed.Fruit fly optimization algorithm (FOA) is used to optimize PI parameters of
