Evaluation of thermal history and defect in friction stir processing of as-cast magnesium AZ91
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
Friction stir processing (FSP) is a thermos-mechanical process for modifying the microstructural and material properties of metals. FSP also can be used for mechanical alloying and producing metal matrix composites. Due ...
Single sensor three-phase permanent magnet synchronous motor drive based on Luenberger style-observers
(
IEEE
, 2012 , Conference Paper)
This paper presents a technique to estimate phase currents and rotor position in a vector-controlled PMSM drive using only dc-link current measurement. Three cascaded Luenberger style observers were used to perform this ...
The progression of Qatar's natural gas industry and its role in global energy market
(
Royal Geographical Society
, 2011 , Conference Paper)
Qatar is the third largest country in the world in natural gas reserves with almost 900 trillion cubic feet. Since the mid of 1980s, after deep studies of the general prospect, Qatar has started to develop its largest field ...
Damage detection using enhanced multivariate statistical process control technique
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
This paper addresses the problem of damage detection technique of structural health monitoring (SHM). Kernel principal components analysis (KPCA)-based generalized likelihood ratio (GLR) technique is developed to enhance ...
Deep Learning for RF-Based Drone Detection and Identification: A Multi-Channel 1-D Convolutional Neural Networks Approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Commercial unmanned aerial vehicles, or drones, are getting increasingly popular in the last few years. The fact that these drones are highly accessible to public may bring a range of security and technical issues to ...
Novel hybrid physical layer security technique in RFID systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
In this paper, we propose a novel PHY layer security technique in radio frequency identification (RFID) backscatter communications system. In order to protect the RFID tag information confidentiality from the eavesdroppers ...
Towards a Hierarchical Multitask Classification Framework for Cultural Heritage
(
IEEE Computer Society
, 2019 , Conference Paper)
Digital technologies such as 3D imaging, data analytics and computer vision opened the door to a large set of applications in cultural heritage. Digital acquisition of a cultural assets takes nowadays a couple of seconds ...
Event-triggered fault detection for discrete-time linear systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper the problem of event-triggered fault detection filter for discrete-time linear systems is considered and a multi-objective formulation of the problem is presented based on H, H- and generalized H2 performance ...
Neuro-fuzzy classifier for corneal nerve images
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Alterations in the corneal nerves have been associated with changes in the neuropathy condition of a patient suffering from chronic diseases. A corneal confocal microscope provides a non-invasive way to capture a series ...
A general multicompartment lung mechanics model with nonlinear resistance and compliance respiratory parameters
(
IEEE
, 2014 , Conference Paper)
In this paper, we develop a nonlinear multicompartment lung mechanics model that accounts for nonlinearities in both the airway resistances and the lung compliances. Many models assume that the airway resistances for a ...
