China's transmission lines are widely distributed. The power department spends huge manpower and material resources every year on line patrolling. development of Unmanned Aerial Vehicle (UAV) technology provides a new inspection method for overhead In the present days, most images drones based monocular cameras. Due to limitations two-dimensional images, this detection is not sufficient. Considering issue that defects ideal in complex natural environment background, paper deep imaging UAV...

A single-vibration signal is no longer adequate to fulfill the requirements of intelligent fault diagnosis (IFD) bearings in complex systems. With rapid advancement industrial Internet Things, IFD methods based on multimodal information fusion have gained popularity. Acoustic signals are noninvasive, easily captured, and a wide monitoring range. Therefore, acoustic-vibration (AVFIFD) holds promising application prospects. Nevertheless, current AVFIFD suffer from two limitations that lead...

The depletion systems defined by the general purpose evaluated nuclear data libraries are unnecessarily complex for most applications in reactor physics analysis. However, corresponding compression methods confronted with two difficulties. On one hand, number of possible compressed is excessively large. other complicated neutronic-depletion coupling effects should be properly considered. In spite legacy empirical-based or semi-empirical-based methods, a generalized system method based on...

In the field of reactor computational physics, burnup equation is established according to chain, and solution core calculation.

The transmutation trajectory analysis (TTA) method is a traditional analytic depletion calculation algorithm. It’s capable of providing very accurate solutions with cutoff value being sufficiently small, but the main drawback expensive time consumption. In this paper, problem was rephrased as directed-graph module additional properties attributed to vertices and edges. Based on model new approach for TTA implementation conducted, which dynamic programming technique could be introduced...
