It is a research topic of practical significance Rubber Brake Pad to study the path planning technology of mobile robot navigation technology.Aiming at the problems of slow convergence speed, redundant planning path, and easy to fall into local optimal value of ant colony algorithm in a complex environment, a robot path planning based on improved a

The discovery of plastics as useful materials for human existence, providing comfort and ease has now turned into a menace in the society and a pain in the neck as plastics have also become co-habitat of the human ecosystem.Plastics were made by men, but plastics now live way longer than the men who gave them the privilege of existence.Since these

Thermohaline staircases are stepped structures of alternating thick mixed layers and thin high-gradient interfaces.These structures can be up to several tens of metres thick and are associated with double-diffusive mixing.Thermohaline staircases occur across broad swathes of the Arctic and tropical and subtropical oceans and can increase rates of d

Expressions for the pulsating or beam strengths of many popular metallic gear materials are derived based on the tensile strength and endurance ratio.The strength values predicted are for a reliability of 99% at load cycles corresponding to that of the endurance strength of the materials.The expressions are based on the consideration of the revised
