Abstract: A process equipment system of hydraulic oil circuit blocks and an automated production line thereof, which relates to the field of mechanical processing technology. In view of the problem of low production efficiency in the positioning and processing of hydraulic oil circuit blocks, based on the six-point positioning principle, the workpiece is achieved the six-point positioning by the support components, positioning devices, and clamping devices on the upper layer of the base. The clamping device is capable to move along the chain, so as to adjust and change the clamping position, and can achieve processing five surfaces through one-time clamping of oil circuit blocks, improving positioning accuracy and processing efficiency, meeting the needs of automated production.

Abstract: An inversion method for seismic wavelets and reflection coefficients, in which it is assumed that the seismic wavelets have compact support, and are smooth, and the reflection coefficients are relatively sparse. Corresponding optimization problems for the inversion of seismic wavelet and reflection coefficient sequence are constructed. By using alternating iteration, the joint inversion problem of the seismic wavelets and the reflection coefficients, which is based on compact smoothness and relative sparsity, is divided into a seismic wavelet inversion subproblem and a reflection coefficient inversion subproblem. The two subproblems are solved using a proximal algorithm. A system for implementing the inversion method is also provided herein.

Abstract: Provided are an SOP management method and apparatus for a power battery pack, and an electric vehicle. The SOP management method includes: obtaining a SOP value of each parallel battery branch in a power battery pack; and obtaining a current total SOP value of the power battery pack according to the SOP value of each parallel battery branch. In the present application, in a multi-branch-parallel power battery pack, an SOP value of each parallel branch is first subjected to refined estimation according to an operation condition of each parallel branch, and then the total SOP of the power battery pack is estimated from the whole system level, and the problem of statistical distortion of the total SOP of the power battery pack is solved, thereby effectively improving the safety and stability of use of the battery.

Abstract: Surprisingly, electric fields can induce a dramatic response in soft materials made from nonconducting biopolymers. Capsules made from Alginate, Chitosan, and Gellan gum, all of which are charged polysaccharides and are biocompatible and biodegradable. Each capsule is formed by crosslinking biopolymer chains via physical (ionic/electrostatic) interactions. Under a DC electric field, the capsules rupture and disintegrate in a span of less than five minutes. The mechanism for the electroresponse is attributed to electrophoretic rearrangement of ions and/or polyelectrolyte chains in the capsule. Alginate capsules first swell anisotropically on their side closer to the anode (+ electrode). Cations migrate away from the anode, thereby lowering the crosslink density on that side. As further crosslinks are lost from the anode side, the capsule eventually breaks. A valve design utilizes an orifice that is blocked by a capsule and the valve is opened when the capsule is dislodged by the field.

Abstract: Implementations of the present specification provide an enhanced training method for an image recognition model. A predetermined quantity or predetermined proportion of samples are randomly selected from a first sample set as a seed sample for extension to obtain several extended samples. The extended sample is obtained by adding disturbance to an original image without changing an annotation result. In a sample extension process, disturbance values are arranged towards neighborhood in predetermined distribution with a reference pixel as a reference, so that real disturbance can be well simulated. Because the annotation result of the extended sample remains unchanged after the disturbance is added, an image recognition model trained by using the extended sample can well recognize a target recognition result of an original image, thereby improving robustness of the image recognition model.
