Bivariate postprocessing of wind vectors

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We introduce three novel bivariate postprocessing approaches and analyze their performance for joint postprocessing of bivariate wind‐vector components in Germany. Bivariate vine‐copula‐based models, a bivariate gradient‐boosted version of ensemble model output statistics (EMOS), and a bivariate distributional regression network (DRN) are compared with

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Elliptic variational problems with indefinite nonlinearities

Topological Methods in Nonlinear Analysis, 1997
It is established the existence of at least one solution for the semilinear elliptic problem \[ -\triangle u + u = \lambda|u|^{q-2}u-h(x)|u|^{p-2}u, \qquad u > 0 \quad \text{in }\mathbb{R}^N, \] where \(h > 0\) is a continuous function on \(\mathbb{R}^N\) satisfying \(\int_{\mathbb{R}^N} h^{q/(q-p)} dx < \infty\), \(2 < q < p < 2^* = 2N/(N-2),\) \(N ...

Elliptic perturbations for Hammerstein equations with singular nonlinear term

Electronic Journal of Differential Equations, 2006
We consider a singular elliptic perturbation of a Hammerstein integral equation with singular nonlinear term at the origin. The compactness of the solutions to the perturbed problem and, hence, the existence of a positive solution for the ...

Robust Partial Multi‐Label Learning Under Dual Noise via Joint Subspace Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Partial Multi‐label Learning (PML) deals with the ambiguity where each instance is annotated with a set of candidate labels, and only a subset of which is valid. While existing PML methods focus primarily on label disambiguation, they often rely on the assumption of a clean feature space.

Positive solutions fo nonlinear elliptic eigenvalue problems

, 1970
We shall study a class of mildly nonlinear elliptic eigenvalue problems which are suggested by several recently occurring problems concerning the steady state temperature distribution of a physical medium in which heat is being generated nonlinearly. ; © 1970 Indiana University Mathematics Department.
