This paper describes a system that is able to localize and detect sound sources in the presence of interfering noise and reverberation from the stereo sound recording. First, a computational auditory scene analysis (CASA) based binaural front-end is applied to generate the binaural cues, interaural time and level differences (ITDs & ILDs). Second, based on the probabilistic nature of the binaural...
The work deals with the curing time effect on the mechanical behaviors of cement solidified dredged sediment (DS). For three DSs solidified by 100 kg cement per m3 sediment, unconfined compressive strength (UCS) tests, consolidated undrained triaxial compression tests were carried out. Test results show water content and failure strain decrease with the increasing of curing time, while UCS and deformation...
The present work deals with the estimation of the average floc size of fine sediment particles using sedimentation data. Through particle size distribution tests of sediment under dispersion and flocculation situation, the criticle flocculation particle size was determined as 15μm. By theoretical analysis, floc sedimentation velocity formula was built based on the zero density flux at any cross section...
Sedimentation column test is adopted to study the natural sedimentation rules of floatation full tailing and dredged sediment at storage yard. The study shows that, the double logarithmic coordinates of sedimentation speed and time could be used to divide the sedimentation process of tailing and dredged sediment into the stage of natural sedimentation and the stage of consolidation under deadweight;...
The objectives of this studies were to develop the optimum shoot and ramification number dynamic models for rapeseed (OSRNDMR), and to lay an foundation for Rapeseed Cultivation Simulation - Optimization - Decision Making System (Rape - CSODS), which can design its planting, regulate and control its growth and development, and fulfill its high yield, good quality, high benefits and standard production...
