Thermal conduction physical method based on finite element model (FEM) is utilized in searching for the shortest path between two nodes in complex networks. The thermal flux matrix of nodes is constructed, and the element with the maximal value in each node thermal flux vector indicates one section of the shortest path to the source node. Theoretical(More)
Besides the hardware/software failure of switched Ethernet, the capability of data transmission affects its performance and reliability. After summarizing the influence factors of Ethernet service capability, this paper focuses on the time delay oriented reliability model and analysis method. Based on the operational mechanism analysis of Avionics Full(More)
This is the second part of a series papers on modeling and path planning of the City-Climber robot. This paper presents a path planning method for the City-Climber robot using mixed integer linear programming (MILP) in 3D building environments that consist of objects with primitive geometrical shapes. In order to use MILP to solve obstacle avoidance(More)
1 Variable structure control with sliding mode can provide fine control performance and robustness. However, chattering phenomenon introduced due to discontinuous switching gain limits their applications. To achieve precise tracking performance with reduced chattering effect, fuzzy sliding mode control is introduced and evolutionary simultaneous tuning of(More)
Gradual degradation is the pivotal factor in prognostics analysis while the performance degradation is difficult to get with limit or blurry data. Based on the failure mechanism analysis of axial piston pump, the abrasion resulting from uneven contact between valve plate and cylinder barrel is the crux. With measured value, this paper presents a updated(More)
This is the first part of a series papers on modeling and path planning of the City-Climber robot, a novel wall-climbing robot which can climb walls, move on ceilings and transit between floor and walls. In order to provide the City-Climber with 3D path planning capability to carry out tasks such as cleaning, painting, and building inspection in 3D(More)
