A Monge–Ampère problem with non-quadratic cost function to compute freeform lens surfaces [PDF]
, 2019 \u3cp\u3eIn this article, we present a least-squares method to compute freeform surfaces of a lens with parallel incoming and outgoing light rays, which is a transport problem corresponding to a non-quadratic cost function.

Powering Analysis of Oscillating Foil Moving in Propagating Wave Flow Field [PDF]
한국해양공학회지, 2019 In this study, a two-dimensional oscillating foil with forward speed in a propagating wave flow field was considered. The time-mean power to maintain the heaving and pitching motions of the foil was analyzed using the perturbation theory in an ideal ...

Physical Review Special Topics. Accelerators and Beams, 2006 In an electron storage ring, coupling between dipole and quadrupole Robinson oscillations modifies the spectrum of longitudinal beam oscillations driven by radio-frequency (rf) generator phase noise. In addition to the main peak at the resonant frequency

Robust MFC anti-windup scheme for LTI systems with norm-bounded uncertainty
Scientific Reports, 2021 On the basic of the fact that all signals in the practical system are always bounded, this paper proposes a 4-degree-of-freedom (DoF) anti-windup scheme for saturated systems with parametric uncertainty. A fairly straightforward tuning rule is introduced

A transfer function approach to transient propagation in media with a quadratic frequency dependence of attenuation coefficient [PDF]
The Journal of the Acoustical Society of America, 1986 The propagation of short acoustical pulses in lossy media is presented as a time-varying transfer function (or spatial filter) that acts on the spatial spectrum of the source excitation. The source is a planar source of arbitrary (but separable) spatial and temporal dependence mounted in a rigid baffle.

Quadratic Stability and Singular SISO Switching Systems [PDF]
, 2009 In this note, we consider the problem of determining necessary and sufficient conditions for the existence of a common quadratic Lyapunov function for a pair of stable linear time-invariant systems whose system matrices are of the form A, A-ghT, and ...
