Nash equilibrium bidding strategies in a bilateral electricitymarket

This paper examines bidding strategies in a bilateral market in which generating companies submit bids to loads. A load accepts electricity delivery from the generator with the lowest bid at its bid price as long as this price is not higher than the load's willingness to pay. Necessary and sufficient conditions of Nash equilibrium (NE) bidding strategy are derived based on a generic generating cost matrix and the loads' willingness to pay vector. The study shows that in any NE, efficient allocation is achieved. Furthermore, all Nash equilibria are revenue equivalent for the generators. Based on the necessary and sufficient conditions, this problem is formulated as an optimal assignment problem. Network optimization techniques are applied to calculate NE bid prices for the generators

微合金钢模拟焊接热影响区组织和韧性研究

采用焊接模拟试验方法，研究了不同峰值温度（Tmax）和不同冷却时间（t8/5），对合Ti-N、TI-NB-N两种微合金钢热影响（HAZ）显微组织、奥氏体晶粒度、冲击韧性影响。试验结果表明：Ti-N钢焊接热影响区比Ti-Nb-n钢具有更高的冲击韧性、更适用于大线能量的焊接条件。     

Hydrolysis of Milk Fat with Lipase in Reversed Micelles

Enzymatic hydrolysis of milk fat was studied in a reversed-micelle system consisting of lecithin, water (1% total volume) and butteroil. Candida cylindracea lipase entrapped in the water pools of reversed micelles hydrolyzed surrounding triglycerides. The optimum temperature for enzyme activity was 55°C with an activation energy of 15.4 kcal/mole, while maximum enzyme activity was observed between pH 4 to 6. The molar ratio of water to surfactant (R value) in the system influenced enzyme activity with maximum activity at R = 10. Enzyme activity also increased with increasing surfactant or enzyme concentration.
