Fractional sampling theorem for -bandlimited random signals and its relation to the von neumann ergodic theorem
(Institute of Electrical and Electronics Engineers Inc., 2014)
Considering that fractional correlation function and the fractional power spectral density, for -stationary random signals, form a fractional Fourier transform pair. We present an interpolation formula to estimate a random ...
A density functional theory study of the reconstruction of gold (111) surfaces
(American Chemical Society, 2014)
We studied (p × √3) gold (111) surface reconstructions within the DFT/PW91 approximation. Our findings clearly show that the reconstruction is energetically favorable in unreconstructed surfaces equal to or larger than the ...
Noise-Robust Processing of Phase Dislocations using Combined Unwrapping and Sparse Inpainting with Dictionary Learning
(Institute of Electrical and Electronics Engineers Inc., 2019)
The problem of phase unwrapping from a noisy and also incomplete wrapped phase map arises in many optics and image processing applications. In this work, we propose a noise-robust approach for processing regional phase ...
Numerical Approximation of the Maximum Power Consumption in DC-MGs with CPLs via an SDP Model
(Institute of Electrical and Electronics Engineers Inc., 2019)
This brief addresses the numerical approximation of the maximum power consumption in direct-current microgrids (DC-MGs) with constant power loads through a convex optimizing model. The convex formulation is developed via ...
Sequential quadratic programming models for solving the OPF problem in DC grids
(Elsevier Ltd, 2019)
In this paper, we address the optimal power flow problem in dc grids (OPF-DC). Our approach is based on sequential quadratic programming which solves the problem associated with non-convexity of the model. We propose two ...
A vision-based system for the dynamic measurement of in-plane displacements
(Institute of Electrical and Electronics Engineers Inc., 2014)
Computer vision has advanced markedly in the last decade and has had new applications such as the analysis of the behavior of structures. The analysis of displacement and deformation of structures is an important process ...
Corporation income taxes and the cost of capital: A revision
(2012)
The value of debt tax shields in foundational corporate valuation models by Nobel Laureates Modigliani and Miller (MM) continues to be a controversial issue that is central to our understanding of corporate finance. Rather ...
Stationary axially symmetric relativistic thin discs with nonzero radial pressure
(2012)
A detailed analysis of the surface energymomentum (SEMT) tensor of stationary axially symmetric relativistic thin discs with nonzero radial pressure is presented. The physical content of the SEMT is analysed and expressions ...
An Infinite Family of Magnetized Morgan-Morgan Relativistic Thin Disks
(2012)
Applying the Horský-Mitskievitch conjecture to the empty space solutions of Morgan and Morgan due to the gravitational field of a finite disk, we have obtained the corresponding solutions of the Einstein-Maxwell equations. ...
Effectiveness of a visual noise warning system on noise levels in a surgical ICU: A quality improvement programme
(Lippincott Williams and Wilkins, 2019)
BACKGROUNDThe effects of noise are harmful to patients in the ICU environment, and the latter are particularly noisy places. High noise levels seem to be a factor in sleep disturbance, which can, in turn, result in increased ...
