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

黔西南地区金矿尾矿（渣）潜在资源评价及处理建议

黔西南地区是我国卡林型金矿主要产区之一,已有几十年的开采历史,随着金矿的开采,产生了大量的尾矿资源。为了解黔西南金矿尾矿（渣）资源现状,运用地质块段法、矿物学和地球化学等方法对贞丰—晴隆—安龙地区5个典型金矿尾矿（渣）中金含量、赋存状态及周围环境进行了调查。结果表明：卡林型尾矿（渣）中金以包裹金状态赋存在黄铁矿中,红土型尾矿中金以游离态赋存在铁钛氧化物中。水银洞和烂泥沟金矿尾矿中的金品位超过工业品位,具有二次提金的潜力。同时,对紫马和老万场2个尾矿库周边的土壤、植物和水质进行采样测试,发现样品中的Cd、Hg和As严重超标,对环境有一定的危害。因此,对于未达到工业品位且对环境有影响的黄金尾矿,建议进行复垦种植、采矿充填或加工成建材,这样不仅实现了尾矿（渣）的减量化处理,而且减少了其对周围环境的危害。

Enhancement of the hydrogen storage properties of Mg/C nanocomposites prepared by reactive milling with molybdenum

The effect of Mo on the morphology, crystal structure and hydrogen sorption properties of Mg/C composites prepared by reactive milling was studied. Transmission electron microscopic(TEM) observation shows that Mg/C composites prepared with the addition of Mo are of nanoscale with particle size about 20-120 nm after 3 h of milling under 1 MPaH_2. MgH_2 of tetrahedral crystal structure predominates in the materials with the geometric shape of oblique hexagonal prism. From X-ray diffraction(XRD) and hydrogen content studies, Mo and crystallitic carbon have a synergistic effect on promoting the hydrogenation rate in the reactive milling process. From differential scanning calorimetric(DSC) studies, the dehydrogenation peak temperature of the Mg/C materials with Mo is lowered to 299-340 ℃.     

Proton irradiation damage mechanism of the InAlAs／InGaAs／InAlAs quantum well

InP-based high electron mobility transistors (HEMT) have shown a great potential for national defense and satellite radar in space radiation environment applications. This paper studies the proton radiation damage mechanism of its critical structure InAlAs／InGaAs／InAlAs quantum well. The proton projection range and vacancy defect information are obtained at different incident proton energies of 50keV, 75keV and 200keV by SRIM software. With the increase of proton energy, the proton injection depth is increasing and eventually protons pass through the material layers. Besides, the proton radiation induced vacancy defects numbers around hetero-junction increase first and decrease subsequently, and As vacancies are the main proton radiation induced defects. In addition, non-ionizing energy loss (NIEL) of In_0.52Al_0.48As and In_0.53Ga_0.47As material is computed under different incident proton energies by the analytical model. The change trend of NIEL is identical to the induced vacancy numbers, namely, NIEL first increases and then decreases as the incident proton energy increases. Finally the degrading effect of the radiation-induced As defect is detected in the two-dimensional electron gas in the quantum well, which confirms that the major proton radiation damage mechanism of the quantum well is the induced vacancy defects by NIEL.
