Generalizations of the sampling theorem: Seven decades after Nyquist [PDF]

, 2001
The sampling theorem is one of the most basic and fascinating topics in engineering sciences. The most well-known form is Shannon's uniform-sampling theorem for bandlimited signals.

Uniform versus Nonuniform Axial Power Distribution in Rod Bundle CHF Experiments

Science and Technology of Nuclear Installations, 2014
Rod bundle experiments with axially uniform and nonuniform heat fluxes are examined to explore the potential limitations of using uniform rod bundle CHF data for CHF correlation development of light water reactors with nonuniform axial power distribution

Particle fluctuations in nonuniform and trapped Bose gases

, 2009
The problem of particle fluctuations in arbitrary nonuniform systems with Bose-Einstein condensate is considered. This includes the case of trapped Bose atoms. It is shown that the correct description of particle fluctuations for any nonuniform system of

MIMIC Models for Uniform and Nonuniform DIF as Moderated Mediation Models. [PDF]

, 2020
In this article, the authors describe how multiple indicators multiple cause (MIMIC) models for studying uniform and nonuniform differential item functioning (DIF) can be conceptualized as mediation and moderated mediation models.

Nonuniform Fuchsian codes for noisy channels [PDF]

, 2014
We develop a new transmission scheme for additive white Gaussian noisy (AWGN) channels based on Fuchsian groups from rational quaternion algebras. The structure of the proposed Fuchsian codes is nonlinear and nonuniform, hence conventional decoding ...

A Design Methodology for Low-Loss Interconnects Featuring Air Cavities and Periodically Nonuniform Widths

Applied Sciences
Power consumption in interconnects is a critical constraint on performance improvements in integrated circuits. This paper proposes a novel design methodology to minimize loss in interconnects and address this limitation.

Maximizing Energy Output of Photovoltaic Systems: Hybrid PSO-GWO-CS Optimization Approach

Journal of Techniques, 2023
Photovoltaic (PV) systems suffer from partial shade and nonuniform irradiance conditions. Meanwhile, each PV module has a bypass shunt diode (BSD) to prevent hotspots.

The Effects of Nonuniform Illumination on the Electrical Performance of a Single Conventional Photovoltaic Cell

International Journal of Photoenergy, 2015
Photovoltaic (PV) concentrators are a promising approach for lowering PV electricity costs in the near future. However, most of the concentrators that are currently used for PV applications yield nonuniform flux profiles on the surface of a PV module ...

Nonuniform Dichotomy Spectrum and Normal Forms for Nonautonomous Differential Systems [PDF]

, 2014
The aim of this paper is to study the normal forms of nonautonomous differential systems. For doing so, we first investigate the nonuniform dichotomy spectrum of the linear evolution operators that admit a nonuniform exponential dichotomy, where the ...
