The 3-D needled C/C preforms with different densities deposited by chemical vapor infiltration (CVI) method were used to fabricate C/C-SiC composites by gaseous silicon infiltration (GSI).The porosity and CVI C thickness of the preforms were studied, and the effects of preform density on the mechanical and thermal properties of C/C-SiC composites w
Complete sequence and comparative analysis of the chloroplast genome of coconut palm (Cocos nucifera).
Coconut, a member of the royal nomadic 5413 rug palm family (Arecaceae), is one of the most economically important trees used by mankind.Despite its diverse morphology, coconut is recognized taxonomically as only a single species (Cocos nucifera L.).There are two major coconut varieties, tall and dwarf, the latter of which displays traits resulting
Two-Stage Robust Security-Constrained Unit Commitment Model Considering Time Autocorrelation of Wind/Load Prediction Error and Outage Contingency Probability of Units
The conservativeness of unit commitment models-based robust optimization (RO) depends on the modeling of uncertainty sets.This paper proposes a new two-stage robust security-constrained unit commitment (SCUC) model, which aims at minimizing the operating cost in the base scenario while guaranteeing that the robust solution can be adaptively and saf
