Precise radius estimation is of high interest for rebar and pipe characterization but very challenging. In this work, we present a novel 3D frequency-domain full-waveform inversion (FWI) approach with which the geometrical information of subsurface cylindrical objects and the dielectric properties of the penetrating medium are simultaneously extracted from ground penetrating radar (GPR) data. The...
In this paper, a systematic distributed optimization approach is proposed based on a fictitious play concept. The convergence of the algorithm is proven under the game theory framework. The result is equivalent to a consensus problem. It introduces a novel perspective to study the consensus problem. Such an equivalence is illustrated by numerical cases.
Preprocessing is generally used for data analysis in the real world datasets that are noisy, incomplete and inconsistent. In this paper, preprocessing is used to refine the inconsistency of the prototype and partition matrices before getting involved in the collaboration process. To date, almost all organizations are trying to establish some collaboration with others in order to enhance the performance...
This paper addresses the problem of sweep-based persistent surveillance (SBPS) using multiple Unmanned Aerial Vehicles (UAVs). Due to the variation of priority distributed in the area under surveillance, a novel concept of level-of-interest (LoI) is introduced to represent the relative priorities of the target areas. Inspired by an “age”- related algorithm in literature, we develop a novel recursive...
The autopilot design of a side jet and aero-fin blending control air-to-air missile is discussed in this paper and a Model Reference Variable Sliding Structure (MRVSS) method is presented. The side jets are in the discontinuous on-off pulse forms which are different from the conventional continuous side jets. The control parameters are sought though Genetic Algorithm (GA). Further, a novel adaptive...
