Comments on “Wind Gust Detection and Impact Prediction for Wind Turbines”

open access: yesRemote Sensing, 2018
We refute statements in “Zhou, K., et al. Wind gust detection and impact prediction for wind turbines. Remote Sens. 2018, 10, 514.” about the impracticality of motion estimation methods to derive two-component vector wind fields from single ...

Representation Learning via Quantum Neural Tangent Kernels

open access: yesPRX Quantum, 2022
Variational quantum circuits are used in quantum machine learning and variational quantum simulation tasks. Designing good variational circuits or predicting how well they perform for given learning or optimization tasks is still unclear. Here we discuss

A New Iterative Method for Solving General Mixed Variational Inequalities [PDF]

open access: yes, 2008
The general mixed variational inequality containing a nonlinear term φ is a useful and an important generalization of variational inequalities. The projection method cannot be applied to solve this problem due to the presence of the nonlinear term. To

Convergence and stability of a three-step iterative algorithm for a general quasi-variational inequality problem

open access: yesFixed Point Theory and Applications, 2006
We consider a general quasi-variational inequality problem involving nonlinear, nonconvex and nondifferentiable term in uniformly smooth Banach space. Using retraction mapping and fixed point method, we study the existence of solution of general quasi ...
