In this paper, the authors have provided a brief review of the recent advances in the Shannon sampling theory. In particular, they discuss the work related to 1-D signal reconstruction involving the samples taken below the Nyquist rate using nonlinear/tim... see more

The essential part of Cognitive Radio (CR) is spectrum sensing, so that the underutilized spectrum could be detected to improve the spectrum efficiency. For this purpose, a wide range of frequency bands are considered and locations of multiple occupied sp... see more

In Classical Geostatistics or Design Based Geostatistics, there is a great need for research that creates and/or explores methods of geospatial data sampling. In addition to this complex subject, some papers present solutions that use theoretical and prac... see more

Inhibition of corrosion of aluminium alloy AA8011in 1.0 M Hydrochloric acid (HCl)by Moringa oleifera (MO) leaves extract has been studied using weight loss and electrochemical techniques. A summary of corrosion rate at different concentrations over a rang... see more

In this study, we propose compressive sampling matching pursuit (CoSaMP) algorithm for sub-Nyquist based electronic warfare (EW) receiver system. In compressed sensing (CS) theory time-frequency plane localisation and discretisation into a N×N grid in uni... see more

This work proposes a methodology for the phase estimation in sub-bands of a non-uniform response channel. The novelty of this proposal lies in the use of a modulation format in QSPK (Quadrature Phase Shift Keying) quadrature-phase modified as a test signa... see more

Cathodic electrodeposited copper oxide thin films were prepared using 0.1 M aqueous (distilled water) copper sulphate solution onto the surface of stainless steel substrates. Deposited samples were characterized for structural and morphological analysis u... see more

This research aimed to study corrosion behavior and evaluated lifetime of the metal sheet cladding and roofing when exposed to actual usage environment using electrochemical impedance spectroscopy (EIS) test method. The sample plates were galvanized steel... see more

A new technology for predicting chatter in turning, based on simulation of the cutting process in time and frequency domains using the Nyquist diagram has been developed. The cutting process is presented as carried out in an elastic closed-loop technologi... see more
