A decoupling-design strategy for high sound absorption in subwavelength structures with air ventilation [PDF]

open access: yesJASA Express Letters, 2022
A strategy based on the decoupling design of two elementary structures, both made of coiled-up channels, is proposed. One channeling structure is designed for blocking sound transmission, while the other element is used for absorbing sounds at low ...

Entry Guidance Command Generation for Hypersonic Glide Vehicles Under Threats and Multiple Constraints

open access: yesIEEE Access, 2022
A novel entry guidance command generation (EGCG) method for hypersonic glide vehicles (HGVs) is proposed in this paper. Apart from the conventional path constraints, terminal constraints, and multiple stationary geographic constraints, the method takes ...

SimpleTrack: Rethinking and Improving the JDE Approach for Multi-Object Tracking

open access: yesSensors, 2022
Joint detection and embedding (JDE) methods usually fuse the target motion information and appearance information as the data association matrix, which could fail when the target is briefly lost or blocked in multi-object tracking (MOT).

Multistage Cooperative Trajectory Planning for Multimissile Formation via Bi-Level Sequential Convex Programming

open access: yesIEEE Access, 2020
Owing to the highly nonlinear dynamics and high number of nonlinear constraints, it is exceedingly difficult and computationally expensive to solve the cooperative trajectory planning problem of multimissile formation using existing approaches.

New Insights into a Three-Sub-Step Composite Method and Its Performance on Multibody Systems

open access: yesMathematics, 2022
This paper develops a new implicit solution procedure for multibody systems based on a three-sub-step composite method, named TTBIF (trapezoidal–trapezoidal backward interpolation formula).

On the stabilization of leading-edge vortices with different reduced frequencies over finite-aspect-ratio pitch-up wings

open access: yesAIP Advances, 2020
An implicit large-eddy simulation method is used to numerically simulate the flowfield around a finite-span rectangular wing in pitch motion. The effect of the reduced frequency (k) on the stability of the leading-edge vortex (LEV) is studied.
