Patent number: 11982065Abstract: A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.Type: GrantFiled: October 24, 2023Date of Patent: May 14, 2024Assignee: Nanjing Hydraulic Research InstituteInventors: Binhua Xu, Ning He, Yanbin Jiang, Zhangchun Wang, Zhikun Yan, Yanzhang Zhou, Guirong Zhang, Yajun Qian, Xinjie Zhan, Zhongliu Zhang, Bin He, Denghua Li, Yang Kong, Yuting Xie, Xiang Yin

Patent number: 11934954Abstract: A pure integer quantization method for a lightweight neural network (LNN) is provided. The method includes the following steps: acquiring a maximum value of each pixel in each of the channels of the feature map of a current layer; dividing a value of each pixel in each of the channels of the feature map by a t-th power of the maximum value, t?[0,1]; multiplying a weight in each of the channels by the maximum value of each pixel in each of the channels of the corresponding feature map; and convolving the processed feature map with the processed weight to acquire the feature map of a next layer. The algorithm is verified on SkyNet and MobileNet respectively, and lossless INT8 quantization on SkyNet and maximum quantization accuracy so far on MobileNetv2 are achieved.Type: GrantFiled: September 22, 2021Date of Patent: March 19, 2024Assignee: SHANGHAITECH UNIVERSITYInventors: Weixiong Jiang, Yajun Ha

Patent number: 9998188Abstract: Embodiments provide a signal transmission apparatus and a downlink signal transmission method. A downlink common channel signal that needs to be sent by using a wide beam is divided into multiple groups of grouped signals; for each group of grouped signals, signal weighting is separately performed on different radio frequency paths in a multi-antenna system; weighted grouped signals are combined to obtain a weighted downlink common channel signal; and the weighted downlink common channel signal is transmitted.Type: GrantFiled: October 21, 2016Date of Patent: June 12, 2018Assignee: Huawei Technologies Co., LtdInventors: Yajun Jiang, Jinlin Zhang
