We demonstrate a hybrid time-domain chirp switch (TDCS) in which the nonlinear chirper is an AlGaAs waveguide and the soliton dispersive delay line is a polarization-maintaining fiber. The hybrid TDCS can restore timing in a switching or transmission system, and when combined with an optical amplifier, it can act as an ultrafast, all-optical regenerator for soliton pulses. The timing restoratio...

The paper is concerned with the thermodynamic analysis of a multi-stream heat exchanger system for Allam cycle and development regenerator flow chart. procedure are described in detail. constructed five double-flow exchangers has 2.5% lower power than ideal exchanging system. Besides, subsequent interaction principle transfer maximal amount proposed: it necessary to begin cooling heating flows ...

Abstract We apply a robust steady state optimization method for stiff delay differential equations to the economic of fluidized catalytic cracking unit. Stiff systems appear in this case due different time scales gas and fluid phase. Delays result from catalyst hold-ups standpipes connecting riser regenerator. show that proposed can cope with stiffness delays. Moreover, is capable simultaneousl...

In this paper, the SCO2 Brayton regenerative and recompression cycles are studied optimized for a next-generation solar power tower under maximum cycle temperature of over 700 °C. First, steady-state thermodynamic model is developed validated, impacts different operating parameters on three critical performance indexes, including thermal efficiency, specific work, heat storage difference, analy...
