To minimize the effects of potable water accidental contamination, efficient determination of contamination sources plays a critical role. In this paper, authors apply simulation-optimization method to backward tracking contamination sources in laboratory water supply system. By introducing sodium hypochlorite solution (a substitute for contaminants) from candidate intrusion points into the system,...
Nowadays, identification, dynamical analysis, control and synchronization of fractional dynamical systems have become a focus topic in the nonlinear research fields. Researchers always us a linear time invariant transfer function (LTI) to approximate the fractional transfer function in related numerical investigation and then put their results into circuits designing, signal processing, etc. In this...
The tolerance of coupling slots is a major factor to determine the performance of the waveguide slot array. Consequently, it is significant to discuss the effects of coupling slots tolerance on the slot array performance. In this paper, the effects of slot dimensions on the resonance frequency are analyzed at first. Secondly, the effects of equal-area bulletheaded slot on the resonance frequency is...
Based on flexible multi-body dynamics theory and Lagrange's equation the mechanical system dynamics model of the three-arm bridge detected vehicles boom is set up. Through the numerical solution of dynamic simulation in combination with analysis software, it is proved that the differential equations of the bridge detection vehicle arm can accurately describe all kinds of the dynamic characteristics...
