3D lidar-based simultaneous localization and mapping (SLAM) is a well-recognized solution for mapping and localization applications.However, the typical 3D lidar sensor (e.g., Velodyne HDL-32E) only provides a very limited field of view vertically.As a result, the vertical accuracy of pose estimation suffers.This paper aims to alleviate this proble
Maritime pilotage is an important guarantee for the safety of water traffic in port.The pilot is affected by the complex port environment, the differences of crew and equipment of different ships, the physical and psychological pressure of the pilot himself, as well as the management factors from the pilot station and maritime safety administration
OBJECTIVE: This study aimed to evaluate the importance of a distal proximal contact on the load transfer to the posterior region of the mandible by non-splinted adjacent implant-supported crowns using photoelastic stress analysis.MATERIAL AND METHODS: A rectangular model (68x30x15 mm) was made of polymethylmethacrylate resin to simulate half of the
The ventilator of the heating tower and the circulating pump Embellishments of the anti-freeze solution are the main electrical equipment of a heating tower heat pump system, besides the compressor.By controlling the working frequencies of the ventilator of the heating tower and circulating pump of the anti-freeze solution, the effects of the opera
