A sensitivity analysis of the linear complementarity programming model: Appalachian steam coal and the natural gas market

There have been extensive attempts in recent years to perform spatial equilibrium analysis of commodity markets, particularly that of energy. Most of these attempts have been based on linear programming transportation models, and more recently quadratic programming models. Unfortunately, neither of these modelling approaches can deal with the case of multi-commodity analysis with non-symmetric regression coefficients. In this paper, we overcome this problem by employing the linear complementarity programming model. In addition, we show how the model can be applied to coal and gas energy flows within a single region. Future potential applications of the model are also implied.     

辽东含硼岩系条痕状角闪混合岩特征及其找矿意义

痕状角闪混合岩与其围岩变（浅）粒岩为渐变过渡关系.并呈现一些特殊的结构构造.其岩石化学成份变化波动性较大,说明岩石化学成分不稳定,与矿化含量的不稳定性一致.其特殊的岩石化学组成显示为混合岩特征.条痕状角闪混合岩石稀土总量ΣREE的平均值为207.18 ppm;（Ce/ΣY平均值为3.25;La/Yb为平均值为 6.48,δEu平均为 0.48,Eu/Sm平均值为0.16.这些特点与里尔峪组的各种变（浅）粒岩相似,是层状混合花岗岩.     

Electron transport in direct methanol fuel cells

A three-dimensional (3D), two-phase, isothermal model of direct methanol fuel cells (DMFCs) was employed to investigate effects of electron transport through the backing layer and the land in bipolar plates. It was found that the electronic resistance of the backing layer, affected by backing layer electronic conductivity, backing layer thickness and flow channel width, played a relatively important role in determining the current density distribution and cell performance. In order to ignore the electron transport effect on the average current density, the minimum electronic conductivity of the backing layer has to be 1000 S m⁻¹, with the relative error in the average current density less than 5%, under the given conditions.
