Rough Volterra equations 1: the algebraic integration setting [PDF]
, 2008 We define and solve Volterra equations driven by an irregular signal, by means of a variant of the rough path theory called algebraic integration. In the Young case, that is for a driving signal with H\"older exponent greater than 1/2, we obtain a global

Fire Control System Operation Status Assessment Based on Information Fusion: Case Study
Sensors, 2019 In traditional fault diagnosis strategies, massive and disordered data cannot be utilized effectively. Furthermore, just a single parameter is used for fault diagnosis of a weapons fire control system, which might lead to uncertainty in the results. This
