A ROBUST DECOMPOSITION OF LINEAR PROGRAMMING USING A GOAL-PARTITIONING METHOD

The Dantzig/Wolfe linear programming decomposition algorithm has had important economicinterpretations as well as a widespread impact on solving large scale linear programming problem.Inthis paper we consider a similar underlying structure,where however there is only one couplinginequality or equation.With this simplification,we demonstrate how to achieve an equitable partitionof the overall coupling resource to individual subproblem constraints through a simple iterationprocedure which appears to be very efficient.

Why the Afshar experiment does not refute complementarity

A modified version of Young's experiment by Shahriar Afshar demonstrates that, prior to what appears to be a “which-way” measurement, an interference pattern exists. Afshar has claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer's Transactional Interpretation easily accommodates the result. It is also shown that the Afshar experiment is analogous in key respects to a spin one-half particle prepared as “spin up along x”, subjected to a nondestructive confirmation of that preparation, and post-selected in a specific state of spin along z. The terminology “which-way” or “which-slit” is critiqued; it is argued that this usage by both Afshar and his critics is misleading and has contributed to confusion surrounding the interpretation of the experiment. Nevertheless, it is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and post-selection spin experiment, in which the particle's preparation state is confirmed by a nondestructive measurement prior to post-selection. In addition, some new inferences about the interpretation of delayed choice experiments are drawn from the analysis.

神经网络方法确定玛北油田岩性油藏含油边界

用常规方法确定岩性油藏含油边界需要一定的井孔资料，导致勘探成本较高，为此引入神经网络方法。先对地震资料进行解释，提取地震特性参数，与已知井的试油结果一起组成神经网络的学习样本集，经训练并绘制测线剖面或平面图，最终确定出含油边界。应用该方法对准噶尔盆地玛北油田二叠系乌尔禾组和三叠系百口泉组油藏进行了含油边界的确定，结果表明，用该方法可以直观地在剖面图上确定油藏的含油边界，这样确定的含油边界能够满足储量计算的要求，且该方法较传统方法有很大的优越性。
