On an Optimal Quadrature Formula for Classes of Functions Given by Modulus of Continuity
Моделирование и анализ информационных систем, 2014 The problem of minimizing the error of a cubature formula on the classes of functions given by modulus of continuity for cubature formulas with fixed nodes on the boundary of gird rectangular localization domain of nodes is considered.

Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects
Advanced Science, EarlyView.A cascaded third‐order nonlinear system generates an itinerant frequency comb with the comb center frequency decoupled from the cavity resonance. This enables arbitrary spectral scaling, flexible spacing adjustments, and real‐time central‐frequency engineering, allowing comb splicing and subdivision. The resulting versatility and reconfigurability open

Low Complexity Golden Code Analytical and Deep Learning-Based Sphere-Decoders for High-Density M-QAM
IEEE Access, 2022 In this paper, we develop low complexity Golden code sphere-decoding (SD) algorithms for high-density M-ary quadrature amplitude modulation (M-QAM). We define the high-density M-QAM as having modulation orders ( $M$ ) of at least 64, i.e.

On optimal quadrature formulae
Journal of Inequalities and Applications, 2000 For integrals involving a nonnegative weight function on a finite interval the author proposes a procedure to construct quadrature formulas which are exact for solutions of linear differential equations and are optimal in the sense of Sard. The author establishes necessary and sufficient conditions for the existence of such formulas.

Lumped modeling of bubbling fluidized beds for high‐temperature processes
AIChE Journal, EarlyView.Abstract Bubbling fluidized beds (BFBs) have been a source of study for multiple decades. Among other applications, they can be used as scalable reactors for the conversion of biomass and waste resources to fuels. Several experimental and computational studies have been devoted to correlating the interplay of hydrodynamics and heat and mass transfer in

Optimal Biasing of a Self-Homodyne Optically Coherent RF Receiver
IEEE Photonics Journal, 2010 We present a technique that achieves the most efficient use of the linear dynamic range of available photodiodes without sacrificing the linearity of the radio-frequency (RF) digital receiver and photonic link based on optical phase modulation and ...
