Recent theories and applications in approximation theory. [PDF]

ScientificWorldJournal, 2015
Approximation theory is a deep theoretical study of methods that use numerical approximation for the problems of mathematical analysis. In practical use, it is typically the application of computer simulation and other forms of computation to problems in various scientific disciplines.

Beam-space direct localisation using passive arrays with random shape errors

The Journal of Engineering, 2019
Passive localisation with high accuracy is attractive in numerous fields. Beam-space direct position determination (BS-DPD) using antenna arrays is a promising positioning method which possesses both excellent performance and moderate complexity ...

Multiple Initial Point Approach to Solving Power Flows for Monte Carlo Studies

Energies, 2022
Power flow solvers typically start from an initial point of power injection. This paper constructs a system of multiple initial points (SMIP) to enable selection of an appropriate initial point, with the objective to achieve a balanced improvement in the

Polytopes and $C^1$-convex bodies [PDF]

Discrete Mathematics & Theoretical Computer Science, 2014
The face numbers of simplicial polytopes that approximate $C^1$-convex bodies in the Hausdorff metric is studied. Several structural results about the skeleta of such polytopes are studied and used to derive a lower bound theorem for this class of ...

Spin-fluctuation theory beyond Gaussian approximation [PDF]

, 2010
A characteristic feature of the Gaussian approximation in the functional-integral approach to the spin-fluctuation theory is the jump phase transition to the paramagnetic state.

Rule induction based on rough sets from information tables having continuous domains

CAAI Transactions on Intelligence Technology, 2019
Information tables having continuous domains are handled by neighborhood rough sets. Two approximations in complete information tables are extended to handle incomplete information.

Longitudinal and Transverse Spin Responses in Relativistic Many Body Theory [PDF]

, 1998
Spin longitudinal and transverse response function are studied by means of the relativistic many-body theory. The spin response functions in the relativistic theory are largely reduced from those in the non-relativistic theory.

ωk algorithm for multi-receiver synthetic aperture sonar based on exact analytical two-dimensional spectrum

The Journal of Engineering, 2019
Based on the method of deriving two-dimensional wavenumber spectrum by using instantaneous Doppler wavenumber in bistatic synthetic aperture radar, the analytical solution of two-dimensional wavenumber spectrum of multi-receiver synthetic aperture sonar (

Universal Function Approximation by Deep Neural Nets with Bounded Width and ReLU Activations

Mathematics, 2019
This article concerns the expressive power of depth in neural nets with ReLU activations and a bounded width. We are particularly interested in the following questions: What is the minimal width w min ( d ) so that ReLU nets of width w ...
