Multi-objective reactive power optimization of hybrid AC/DC power system considering power system uncertainty
Controlled growth of silicon nanowires by solid-liquid-solid method and their formation mechanism
High quality silicon nanowires (SiNWs) were grown directly from n-(111) silicon single crystal substrate by using Au film as a metallic catalyst. The diameter and length of the formed nanowires are 30-60 nm and from several micrometers to sereral tens of micrometers, respectively. The effects of Au film thickness, annealing temperature, growth time and N-2 gas flow rate on the formation of the nanowires were experimentally investigated. The results confirmed that the silicon nanowires with controlled diameter, length, shape and orientation can be obtained via reasonably choosing and optimizing various technical conditions. The formation process of the silicon nanowires is analyzed qualitatively based on solid-liquid-solid growth mechanism

Stochastic preemptive goal programming to balance goal achievements under uncertainty
Excerpt: Many decision-making problems contain multiple, competing objectives. As a subfield of multi-criteria decision-making, deterministic goal programming represents one of the most common approaches to combine multiple, competing objectives
