This work addresses the development of a distributed switching control strategy to drive the group of mobile robots in both backward and forward motion in a tightly coupled geometric pattern, as a solution for the deadlock situation that arises while navigating the unknown environment.A generalized closed-loop tracking controller considering the le
Despite recent progress, the causes and pathophysiology of post-traumatic stress disorder (PTSD) remain poorly understood, partly because of ethical limitations inherent to human studies.One approach to circumvent this obstacle is to study PTSD in a valid animal model of the human syndrome.In one such model, extreme and long-lasting behavioral mani
Based on the historical fault data of pantograph of CRH380BL EMUs, the fault distribution law of four main fault parts was studied by using the method of reliability data Loft Bin Storage analysis, and then the reliability level of pantograph system was evaluated.ADD and air supply pipe, air supply pipe line, 10-X01 relay and pantograph airbag were
Abstract The feather-like hierarchical zinc oxide (ZnO) was synthesized via successive ionic layer adsorption and reaction without any seed layer or metal catalyst.A possible growth mechanism is proposed to explain the forming process of ZnO feather-like structures.Meanwhile, the photo-electronic performances of the Clocks feather-like ZnO have bee
Based on the example of 6Dg type diesel locomotives, the paper presents a new maintenance strategy concerning periodical checks at the P1 maintenance level.Currently, such locomotives are sent off to service points every 102 hours of operation or every 14 days for a P1 level check.Studies demonstrate that the average distance to be covered by a loc
