Abstract:
The present invention provides an operational-task-oriented system and method for dynamically adjusting operational environment applicable to a computer cluster. Each operational node of the computer cluster has two or more operational systems installed. After receiving the operational task, the control node estimates the time required for completing different tasks requiring different operational systems by appropriate operational nodes and compares the estimated finish time and the assigned finish time for judging how to adjust the operating system running in the operational nodes. Thereby, the operational task can be completed in the assigned finish time. Another method is to use the control node to analyze the proportions of the tasks requiring different operational systems in an operational task and hence adjusts the operational system running in an operational node according to the proportion of requirement. Thereby, the operational task can be completed in the shortest time.

Abstract:
An image correlation for images having speckle pattern is evaluated. Modulation transfer function (MTF) curves of speckle-pattern images captured at different times are figured out. Whether a correlation value between the MTF curves meets a threshold is checked. If the correlation value is smaller than the threshold, speckle-pattern images are re-selected for re-figuring out the MTF curves and the correlation value. Thus, error of strain and displacement for digital image correlation owing to blurring images of the on-moving target object is figured out; calculation time of the digital image correlation is reduced; and accuracy on measuring physical parameters of the target object before and after movement is improved for digital image correlation.

Next, the processing unit calculates a plurality of difference values between the characteristic value of each frame and that of the previous frame and between the characteristic value of the subsequent frame and that of the current frame. Store a data set, which is produced by corresponding the plurality of difference values between all frames of each video to the time axis, to the storage unit. Finally, the processing unit compares a data set of any video with a plurality of data sets of other videos and gives a search result.

Abstract:
A micro-nano fluid damper includes a sleeve, a piston assembly and a micro-nano fluid. The sleeve has an accommodating space. The piston assembly has a piston head and at least one piston rod. The piston assembly is movably disposed in the accommodating space. The piston rod extends out of the sleeve from a side of the piston head. The micro-nano fluid is filled between the sleeve and the piston assembly, and the micro-nano fluid flows in the accommodating space by the back-and-forth movement of the piston. When a shear strain rate of the micro-nano fluid is greater than 1 s−1, an exponent of velocity of the micro-nano fluid damper is less than 1, and the micro-nano fluid has a shear thinning threshold and a shear thickening threshold.

Abstract:
A system of computing surface reconstruction, in-plane and out-of-plane displacements and strain distribution utilizes the optical switching element to switch the reference beam to analyze the images of the test object before and after deformation, to measure the topography, in-plane and out-of-plane displacements and surface two-dimensional strain distribution on the test surface of the test object, and thus to increase the measurement range on the test surface of the test object with the use of image registration. Thereby, the complexity and error of scanning the test object can be reduced. Such a system need not to move the image capturing device or test object to generate relative displacement for reaching the measurement effect of the test surface of the test object in three-dimensional coordinates.
