摘要： In a process for producing cyclohexylbenzene, hydrogen, and benzene are contacted in a first reaction zone under conditions effective to produce a product effluent containing residual benzene in the vapor phase and cyclohexylbenzene in the liquid phase. The product effluent is separated into a first stream that is rich in residual benzene in the vapor phase as compared to the product effluent and a second stream that is rich in cyclohexylbenzene in the liquid phase as compared to the product effluent. At least a portion of the first stream is cooled to condense at least a portion of the residual benzene in the vapor phase to the liquid phase and produce a condensate stream. At least a portion of the condensate stream is recycled to the first reaction zone.

摘要： Methods and apparatus, including computer program products, implementing and using techniques for performing temporal motion vector filtering in digital video are disclosed. A recursive hierarchical process is used to determine a motion vector. In the recursive hierarchical process, a neighborhood of old motion vectors is filtered to generate a first estimated motion vector for an image patch in a pair of two image frames. The filtering process uses multiple vectors in a neighborhood around the old motion vector to improve the prediction of the first estimated motion vector. The temporal vector partitioning process separates motion vectors associated with an object from motion vectors associated with a background before selecting a best motion vector, which improves the selection process. The process also works well in the absence of object/background boundaries, as in this case the outlier (incorrect) vector or vectors will be separated out from the good vectors.
摘要翻译：公开了包括计算机程序产品在数字视频中执行时间运动矢量滤波的实现和使用技术的方法和装置。递归层次过程用于确定运动矢量。在递归分层处理中，对旧的运动矢量的邻域进行滤波，以生成一对两个图像帧中的图像块的第一估计运动矢量。滤波处理使用旧运动矢量周围的邻域中的多个向量来改善第一估计运动矢量的预测。在选择最佳运动矢量之前，时间矢量分割过程将与对象相关联的运动矢量与与背景相关联的运动矢量分离，这改善了选择过程。该过程在没有对象/背景边界的情况下也很有效，因为在这种情况下，异常值（不正确）的向量或向量将从良好向量中分离出来。

摘要： Methods and apparatus, including computer program products, implementing and using techniques for computing motion vectors in a digital video sequence are disclosed. A recursive hierarchical method is used to determine a motion vector by using multiple resolution levels of the image frames. A best motion vector is first determined for the lowest resolution level. The best motion vector is propagated to a higher resolution level, where some adjustments are made and a new best motion vector is determined. The new best motion vector is propagated to yet another higher resolution level, where more adjustments are made and another new best motion vector is determined. This process is repeated until the highest, original, resolution level has been reached and a best motion vector has been identified. The identified best motion vector at the original resolution level is used for performing motion compensation.
