云南炉坪铅多金属矿床地质特征及找矿方向

云南鹤庆炉坪铅多金属矿床是新发现的—个大型隐伏矿床,位于北衙超大型金多金属矿床北部,属北衙金多金属矿田斑岩—热液成矿体系的组成部分,是该成矿体系中的新类型矿床.对比北衙矿区的成矿特点,认为在北衙向斜构造的轴部应该存在构造薄弱地带,能够为万硐山正长斑岩成矿体系中的成矿流体运移提供通道和赋存空间,同时结合良好的Pb-Au-Ag-Zn-Cu-As-Sb组合异常显示,通过钻探验证而发现的铅多金属隐伏矿床.矿体沿中三叠统北衙组灰岩与下三叠统青天堡组砂泥岩层间及中三叠统北衙组灰岩内层间破碎带产出,已探获铅金属量大于80万t,金金属量近20 t,银金属量大于1000 t、锌金属量大于11万t.文章在总结矿区地质特征的基础上,指出了新的找矿方向.

液浮靶标靶板的设计与实验

为了设计光轴一致性检测中用于基准光轴空间角监测的液浮空间角靶标,确定了液浮靶板选择原则。首先,利用流体力学对靶板在浮液中的横摇固有周期进行了分析;然后,结合谐振等相关知识,分析了靶板横摇固有周期与浮液震荡周期不同比值下,靶板的稳定情况;最后,确定了靶板横摇固有周期应大于浮液震荡周期的靶板选择原则。通过对不同厚度的圆柱形靶板及半球形靶板的分析,选择横摇固有周期较大的半球形靶板,并通过实验验证了所确定的靶板选择原则的正确性。

Methodology proposal for territorial distribution of greenhouse gas reduction percentages in the EU according to the strategic energy policy goal

A 20% reduction of greenhouse gas (GHG) emissions by 2020 is one of the main objectives of the European Union (EU) energy policy. However, this overall objective does not specify how it should be distributed among the Member States, according to each one’s particular characteristics. Consequently, in this article a non-linear distribution methodology with dynamic objective targets for reducing GHG emissions is proposed. The goal of this methodology is to promote debate over the weighting of these overall objectives, according to the context and characteristics of each member state. First, an analysis is conducted of the situation of greenhouse gas emissions in the reference year (1990) used by the EU for reaching its goal of reducing them by 20% by 2020, and its progress from 1990 to 2007. Then, the methodology proposed was applied for the year 2020 on two territorial aggregation levels following the EUROSTAT Nomenclature of Territorial Units for Statistics (NUTS), in the EU-15 and EU-27 member countries and on a regional level in 19 Spanish Autonomous Communities and Cities (NUTS-2). Weighting is done based on CO₂ intensity, GHG emissions per capita and GHG emissions per GDP. Finally, several recommendations are provided for the formulation of energy policies.     

Tuning the Model Predictive Control of a Crude Distillation Unit

Tuning the parameters of the Model Predictive Control (MPC) of an industrial Crude Distillation Unit (CDU) is considered here. A realistic scenario is depicted where the inputs of the CDU system have optimizing targets, which are provided by the Real Time Optimization layer of the control structure. It is considered the nominal case, in which both the CDU model and the MPC model are the same. The process outputs are controlled inside zones instead of at fixed set points. Then, the tuning procedure has to define the weights that penalize the output error with respect to the control zone, the weights that penalize the deviation of the inputs from their targets, as well as the weights that penalize the input moves. A tuning approach based on multi-objective optimization is proposed and applied to the MPC of the CDU system. The performance of the controller tuned with the proposed approach is compared through simulation with the results of an existing approach also based on multi-objective optimization. The simulation results are similar, but the proposed approach has a computational load significantly lower than the existing method. The tuning effort is also much lower than in the conventional practical approaches that are usually based on ad-hoc procedures.     

The cognitive-behavioral relationship record.

The Cognitive-Behavioral Relationship Record is a technique designed to help individual psychotherapy clients make sense of chronic relationship problems and to encourage them to experiment with new behavioral solutions. In this paper, the reader is given step-by-step instructions on how to use the Relationship Record accompanied by case illustrations. By conceptualizing relationships in terms of the interplay between two individuals’ cognitions and behaviors, the Relationship Record gives therapists a new tool to address the circular causality in relationship systems. In addition to its usefulness as a therapeutic technique, it may be seen as a step toward the integration of family systems into cognitive–behavioral therapy, or, more specifically, the assimilation of strategic therapy techniques and concepts into Aaron T. Beck’s school of cognitive therapy. The Relationship Record joins a movement in psychotherapy integration to enhance individual-based therapies by assimilating interpersonal approaches.
