Improved Discrete Definition of Quadratic Time-Frequency Distributions
(
IEEE
, 2010 , Article)
Computation of a time-frequency distribution (TFD) requires a discrete version of the continuous distribution. This discrete TFD (DTFD) should be free from aliasing and conserve all the important mathematical properties ...
Time-frequency approach to radar detection, imaging, and classification
(
Institution of Engineering and Technology
, 2010 , Article)
One of the central problems in exploiting the radar data is the analysis of atime series. The problem at hand is how to extract the information present in the data and use it to its full potential. Traditionally, radar ...
Multiple-view time-frequency distribution based on the empirical mode decomposition
(
Institution of Engineering and Technology
, 2010 , Article)
This study proposes a novel, composite time-frequency distribution (TFD) constructed using a multiple-view approach. This composite TFD utilises the intrinsic mode functions (IMFs) of the empirical mode decomposition (EMD) ...
Time-frequency signal and image processing of non-stationary signals with application to the classification of newborn EEG abnormalities
(
IEEE
, 2011 , Conference Paper)
This paper presents an introduction to time-frequency (T-F) methods in signal processing, and a novel approach for EEG abnormalities detection and classification based on a combination of signal related features and image ...
Analysis of the time-varying cortical neural connectivity in the newborn EEG: A time-frequency approach
(
IEEE
, 2011 , Conference Paper)
Relationships between cortical neural recordings as a representation of functional connectivity between cortical brain regions were quantified using different time-frequency criteria. Among these, Partial Directed Coherence ...
Opportunistic routing and data dissemination protocol for energy harvesting wireless sensor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Recent advances in environmental sources harvesting technologies is a promising solution to provide sustainable energy sources for wireless sensor networks (WSN). Renewable energy sources such as solar, thermal and ...
Determinants of revenue recognition disclosures: the case of Jordanian industrial listed companies
(
Inderscience
, 2015 , Article)
The focus of this study is on the extent to which IAS 18 is applied by Jordanian industrial companies. Specifically, the objectives of this study are: 1) to investigate the extent of application of IAS 18 in selected ...
Unpublished Material from the Arab Museum of Modern Art at Qatar—Doha I
(
American Research Center in Egypt
, 2011 , Article)
The aim of this article is to shed light on a decorated canopic box with four inscribed canopic jars.
The box with its jars are among a corpus of Ancient Egyptian materials housed in the Arab Museum
of Modern Art at Doha, ...
Fault detection of infinite dimensional systems in presence of disturbances
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this brief paper we are concerned with the fault detection (FD) problem of single-input multi-output infinite dimensional (Inf-D) systems. We develop a geometric methodology to detect a fault in presence of a disturbance ...
How ethics influence intentions to buy counterfeit drugs: perceptions of policymakers, community pharmacists and consumers in Sudan
(
John Wiley & Sons, Ltd.
, 2014 , Article)
Objectives
The ethical attitudes of consumers have been widely explored in the literature as a key factor influencing the purchase of counterfeit products. However, the manner in which consumers make decisions regarding ...
