Although several papers have studied no-idle scheduling problems, they all focus on flow shops, assuming one processor at each working stage. But, companies commonly extend to hybrid flow shops by duplicating machines in parallel in stages. This paper considers the problem of scheduling no-idle hybrid flow shops. A mixed integer linear programming model is first developed to mathematically form...

reflections, shadows, or fragmented occlusion (for example, looking through the branches of a tree). The assumpMost approaches for estimating optical flow assume that, within a finite image region, only a single motion is present. tion may also be violated when the region spans a depth This single motion assumption is violated in common situations discontinuity in the scene. The standard spatia...

In order to determine system parameters for in-process optical measurement for workpiece surface profiles during machining, an experimental system was established to validate theoretical models. It was found that the coolant flow patterns were one of the critical factors, which affect the effectiveness of the measurement. To obtain the flow patterns, an image processing method had been proposed...

The local binary pattern (LBP) provides a simple and efficient approach to gray-scale and rotation invariant texture classification. However, the LBP operator thresholds P neighbors at the value of the center pixel in a local neighborhood and employs a P-bit binary pattern to encode only the signs of the differences between the gray values. Thus, the LBP operator discards some important texture...

background: a pressure ulcer is a complication related to the need for the care and treatment of primarily disabled and elderly people. with the decrease of the blood flow caused by the pressure loaded, ulcers are formed and the tissue will be wasted with the passage of time. objective the aim of this study was to construct blood flow monitoring system on the heel tissue which was under externa...
