A new approach is proposed to generate flexible featrure-based models (FFBM), which can be modified dynamically. BRep/CSFG/FRG hybrid scheme is used to describe
To explore the biological properties of a new neutralmyocardial imaging agent 99mTcN(NOEt)2, preparationand characterization of 99mTcN(NOEt)2, kinetics of blood
Gradual faults and abrupt faults of mechanical systems are differentiated by variation patterns of state var ibles.After the reasons of abrupt faults are analyz
A mechanism of excited arc to be an controlled "ultrasonic emission source" is described. An developed electrical source with an certain frequency bandwidth for
This paper uses Haar wavelet integral operational matrices to approximate the s olution of the optimal control problem with quadratic performance measures. The
