The multistage homotopy-perturbation method: A powerful scheme for handling the Lorenz system
(
Elsevier
, 2007 , Article)
In this paper, a new reliable algorithm based on an adaptation of the standard homotopy-perturbation method (HPM) is presented. The HPM is treated as an algorithm in a sequence of intervals (i.e. time step) for finding ...
Maintaining the genetic health of putative Barbary lions in captivity: an analysis of Moroccan Royal Lions
(
Springer Berlin / Heidelberg
, 2009 , Article)
The last representatives of the Barbary lion (Panthera leo leo), once numerous in North Africa but exterminated from the wild by the 1940s, are believed to be the captive lions descended from the Moroccan Royal Collection, ...

With the widespread use of Internet of things (IoT), mobile phones, connected devices and artificial intelligence (AI), recommender systems (RSs) have become a booming technology because of their capability to analyze big ...
A robust high-resolution time-frequency representation based on the local optimization of the short-time fractional Fourier transform
(
Elsevier Inc.
, 2017 , Article)
The Locally Optimized Spectrogram (LOS) defines a novel method for obtaining a high-resolution time-frequency (t,f) representation based on the short-time fractional Fourier transform (STFrFT). The key novelty of the LOS ...
Phase II monitoring of linear profiles with random explanatory variable under Bayesian framework
(
Elsevier
, 2019 , Article)
Linear profiles monitoring have been successfully implemented in many industrial applications. The design structures of control charts for profiles monitoring are mostly based on two major classifications namely Classical ...
Aluminum nitride (AlN) reinforced electrodeposited Ni-B nanocomposite coatings
(
Elsevier Ltd
, 2020 , Article)
Ni–B nanocomposite coatings containing various concentration aluminum nitride (AlN) nanoparticles (NPs) were developed through a scalable and conventional electrodeposition process. The influence of addition of AlN ...
Impact of CNTs' treatment, length and weight fraction on ordinary concrete mechanical properties
This study investigates the effect of the treatment, length and weight fraction parameters of multi-wall carbon nanotubes (MWCNT) on the mechanical properties of concrete. Mixes with various CNTs’ amounts ranging between ...
