Lightweight LSTM and GRU Design for Data-Driven Rotor Position Error Estimation in IPMSM Drives by Yang Zhao, Chee Shen Lim, Fei Xue, Chao Long, Andrew Huey Ping Tan

“…The proposed lightweight LSTM- and GRU-based neural networks are extensively validated using a 2.2-kW interior permanent-magnet synchronous motors through simulations and experiments for estimating the step- and ramp-type dynamic rotor position errors. The comparative evaluation against the classical iterative rotor position correction method confirms its superiority in terms of estimation speed and accuracy, suggesting a good potential of the data-driven concept in improving electric drives.…”

Evaluation of Peri-Implant Bone Repair in Ovariectomized Rats Submitted to the Implant Placement Functionalized with Anti-Sclerostin by Pedro Henrique Silva Gomes-Ferreira, Paula Buzo Frigério, Nathália Dantas Duarte, Juliana de Moura, Naara Gabriela Monteiro, André Luis da Silva Fabris, Roberta Okamoto

“…The right tibia was used for removal torque and RT-PCR, while the left tibia was collected for micro-CT and laser confocal microscopy. (3) Results: Functionalization with Scl-Ab significantly increased the gene expression of bone markers, especially ALP, in the SHAM Scl-Ab group compared to the other groups (<i>p</i> < 0.05). (4) Conclusions: Some parameters of this study indicate that implants functionalized with anti-sclerostin bone anabolic drug enhance peri-implant bone repair, especially in healthy rats. …”

Design and stability analysis of the multi-pose and multi-function lower limb assist device based on ZMP by ZHOU Xiaochen, SUN Tianxue, ZHANG Baoxu, JIA Bingqi, ZHAO Yanjun

“…ObjectiveTo address the difficulty of traveling for patients with lower limb motor dysfunction and promote the recovery of lower limb function, a multi-posture, multi-functional lower limb assistive device was designed, offering functions for mobility, assisted standing and lower limb rehabilitation training.MethodsThe static simulation was conducted using Ansys software to assess the safety of the device during use; the kinematics and dynamics models of lower limb exoskeleton were established to obtain the spatial posture and theoretical torque of each joint,providing theoretical support for the subsequent prototype fabrication; the "Zero-Moment Point" (ZMP) position model of the human body-assist device system was established, the theoretical ZMP was calculated, and the virtual prototype was imported into Adams software for simulation to obtain the variation in the supporting foot position, the stability of the device was validated by comparing the positions of ZMP and the supporting foot;the physical prototype was constructed.ResultsThe rationality of the prototype design was validated by comparing simulation and experimental data, providing a basis for subsequent research.…”
