The security mechanism of the ship lift has the needs of increasing the friction and being anti-corrosive.This article tried an antirust grease used on wire rope with high friction coefficient (Alice click here IRIS-400M grease) and rayed it with ultraviolet.We find that ultraviolet rays can effectively accelerate the speed of solidification.It nee
The paper presents a technological-spatial model of fishing harbour servicing simultaneously medium- chainsaw file and long-range fishing fleets; two alternate versions are considered: a single-basin and a two-basin approach.The main emphasis is placed to considerations on technological processes associated with services paid in connection with fis
This paper addresses an autonomous navigation method for the autonomous underwater vehicle (AUV) C-Ranger applying information-filter-based simultaneous localization and mapping (SLAM), and its sea trial experiments in Tuandao Bay (Shangdong Province, P.R.China).Weak links in the information matrix in an extended information filter (EIF) can be pru
