Abstract: A detection device includes a frame, a transport mechanism, detection mechanisms, and a grasping mechanism. The transport mechanism includes a feeding line, a first flow line, and a second flow line arranged in parallel on the frame. The detection mechanisms are arranged on the frame and located on two sides of the transport mechanism. The grasping mechanism is arranged on the frame and used to transport workpieces on the feeding line to the detection mechanisms, transport qualified workpieces to the first flow line, and transport unqualified workpieces to the second flow line.

Abstract: The present disclosure provides a ride-hailing method and apparatus, an electronic device and a readable storage medium, and relates to the field of artificial intelligence technologies such as intelligent transportation and deep learning. The ride-hailing method includes: acquiring a rapid ride-hailing request, the rapid ride-hailing request including a departure position and a destination position of a user; determining a target pick-up point according to the departure position and the destination position; obtaining an arrival time from the departure position to the target pick-up point; and outputting the target pick-up point and path planning information from the departure position to the target pick-up point when a target region where the target pick-up point is located is determined as an easy ride-hailing region according to the arrival time. According to the present disclosure, users' ride-hailing time can be reduced, and the users' ride-hailing efficiency can be improved.

Abstract: Described are techniques for updating checkpoint data during a copy process that copies data from a first device to a second device. A portion of data is copied from the first device to the second device. A first calculated value is determined in accordance with a plurality of factors. In accordance with the first calculated value and a threshold ratio, it is determined whether to update the checkpoint data denoting progress of the copying process that copies data from the first device to the second device. If it is determined to update the checkpoint data, first processing is performed that updates the checkpoint data.

Abstract: Various embodiments of the present invention relate to a method and apparatus for data copy. Specifically, in one embodiment of the present invention there is provided a method for data copy, comprising: obtaining a data source on which data copy is to be executed; determining a size P of a block extent based on which the data source is divided; dividing the data source into at least one data block based on the size P of the block extent; and copying data from the data source to a data target in the basic unit of the at least one data block; wherein the size P of the block extent is an integral multiple of a size R of a read/write unit supported by underlying architecture. In one embodiment of the present invention, there is provided an apparatus for data copy.

Abstract: The present invention provides a method and system for constructing a labeled treemap with balanced layout. The method comprises: determining a range of possible densities of leaf nodes based on designated weights of the leaf nodes and a designated treemap region, wherein the density of a leaf node is the area of region on one unit of weight occupied by the leaf node; searching the rang of possible densities for a density that could be fitted on and a labeled treemap that could fit on the density, wherein said density that could be fitted on is referred to that there is at least a labeled treemap for the density in which the area of region occupied by each leaf node is at least the product of the weight of the node and the density; and presenting the labeled treemap on the specified display region.

Abstract: A method for distance definition in a text-to-speech conversion system by applying Gaussian Mixture Model (GMM) to a distance definition. According to an embodiment, the text that is to be subjected to text-to-speech conversion is analyzed to obtain a text with descriptive prosody annotation; clustering is performed for samples in the obtained text; and a GMM model is generated for each cluster, to determine the distance between the sample and the corresponding GMM model.

Abstract: A synergistic composition and method for controlling biological growth in industrial fluids are disclosed, wherein the composition comprises stabilized sodium hypobromite and at least one compound selected from the group consisting of coco alkyldimethylamine oxide, n-coco alkyltrimethylenediamine, tetra-alkyl phosphonium chloride, 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid and 4,5-dichloro-2-n-octyl-4-isothiazoline-3-one.
