Tapered roller bearings (TRBs) are widely used in heavy-load rotating machinery.One of the technical problems in TRBs is the existence of Clothes Airers sharp spikes of the contact pressure in the vicinity of the two ends of the tapered rollers.To suppress the pressure spikes at the roller ends, a straight roller profile is crowned in cylindrical a
Novel Prescribed Performance Control Scheme for Flexible Hypersonic Flight Vehicles with Nonaffine Dynamics and Neural Approximation
This study develops a novel neural-approximation-based prescribed performance controller for flexible hypersonic flight vehicles (HFVs).Firstly, a new prescribed performance mechanism Tinted Sunscreen is exploited, which develops new performance functions guaranteeing velocity and altitude tracking errors with small overshoots.Compared with the exi
A spectrum of epididymis and vas deferens anomalies among children with cryptorchidism: a retrospective multi-center study
Abstract Background Vasoepididymal anomalies are not rare among children with cryptorchidism.They may affect fertility following orchiopexy.Herein, we describe the cases of abnormalities of the vas deferens and epididymis in children undergoing orchidopexy for cryptorchidism.Data Unmanaged Switches were collected retrospectively from six centers pr
Attunement and Multispecies Communication in Fermentation
Terada Honke is a natural sake brewery that utilizes practices like call-and-response and work song to coordinate its fermentation processes across human and microbial participants.I call attention to the concept of attunement, which is the ability to notice, apprehend, and connect with others in meaningful response.Drawing on ethnographic fieldwor
