Cramer-Rao bound investigation of a novel virtually extended nested arc array for 2D DOA estimation
Alexandria Engineering Journal, 2023 This paper exploits a sparse array representation, a novel nested arc array, to generate a virtual non-uniform circular arrays that have been presented and investigated.

Non-uniformity issues and workarounds in bounded-size sampling
The VLDB Journal, 2013 A variety of schemes have been proposed in the literature to speed up query processing and analytics by incrementally maintaining a bounded-size uniform sample from a dataset in the presence of a sequence of insertion, deletion, and update transactions.

Weighted Matrix Completion From Non-Random, Non-Uniform Sampling Patterns [PDF]
IEEE Transactions on Information Theory, 2019 We study the matrix completion problem when the observation pattern is deterministic and possibly non-uniform. We propose a simple and efficient debiased projection scheme for recovery from noisy observations and analyze the error under a suitable ...

Properties of Water Bound in Hydrogels
Gels, 2017 In this review, the importance of water in hydrogel (HG) properties and structure is analyzed. A variety of methods such as 1H NMR (nuclear magnetic resonance), DSC (differential scanning calorimetry), XRD (X-ray powder diffraction), dielectric ...

Bounded cohomology and non-uniform perfection of mapping class groups [PDF]
Inventiones mathematicae, 2001 Using the existence of certain symplectic submanifolds in symplectic 4-manifolds, we prove an estimate from above for the number of singular fibers with separating vanishing cycles in minimal Lefschetz fibrations over surfaces of positive genus. This estimate is then used to deduce that mapping class groups are not uniformly perfect, and that the map ...

On an improved computational solution for the 3D HCIR PDE in finance
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019 The aim of this work is to tackle the three–dimensional (3D) Heston– Cox–Ingersoll–Ross (HCIR) time–dependent partial differential equation (PDE) computationally by employing a non–uniform discretization and gathering the finite difference (FD) weighting

DP-colorings of uniform hypergraphs and splittings of Boolean hypercube into faces
, 2022 We develop a connection between DP-colorings of $k$-uniform hypergraphs of order $n$ and coverings of $n$-dimensional Boolean hypercube by pairs of antipodal $(n-k)$-dimensional faces. Bernshteyn and Kostochka established that the lower bound on edges in

Integral points on elliptic curves and explicit valuations of division polynomials
, 2014 Assuming Lang's conjectured lower bound on the heights of non-torsion points on an elliptic curve, we show that there exists an absolute constant C such that for any elliptic curve E/Q and non-torsion point P in E(Q), there is at most one integral ...

An analytical solution to the multicommodity network flow problem with weighted random routing
Applied Network Science, 2021 We derive an analytical expression for the mean load at each node of an arbitrary undirected graph for the non-uniform multicommodity flow problem under weighted random routing. We show the mean load at each node, net of its demand and normalized by its (
