A Subaperture Motion Compensation Algorithm for Wide-Beam, Multiple-Receiver SAS Systems
Journal of Marine Science and Engineering, 2023 Uncompensated motion errors can seriously affect the imaging quality of synthetic aperture sonars (SASs). In the existing line-by-line motion compensation (MOCO) algorithms for wide-beam multiple-receiver SAS systems, the approximate form of the range ...

An evolutionary strategy based motion estimation algorithm for H.264 video codecs [PDF]
In this paper, we propose a new motion estimation algorithm based on evolutionary strategy (ES) for the H.264 video codec applied to monoscopic video. The proposed technique applies in macroblock basis and performs a parallel local search for the motion ...

Convergence acceleration and accuracy improvement in power bus impedance calculation with a fast algorithm using cavity modes [PDF]
, 2005 Based on the cavity-mode model, we have developed a fast algorithm for calculating power bus impedance in multilayer printed circuit boards. The fast algorithm is based on a closed-form expression for the impedance Z matrix of a rectangular power bus ...

Correcting symmetry imperfections in linear multipole traps [PDF]
, 2018 Multipole radio-frequency traps are central to collisional experiments in cryogenic environments. They also offer possibilities to generate new type of ion crystals topologies and in particular the potential to create infinite 1D/2D structures: ion rings
