A Cryptography Algorithm for Transmitting Multimedia Data Using Quadruple-State CSK
(2015-04-21)A new technique for secure communication is introduced that aims at robustifying classical Chaotic Shift Keying (CSK) methods. The secret data are hidden within the chaotic transmitter states that can change among four ... -
A Smart SCADA System for Oil Refineries
(The 2nd International Conference on Computing Sciences and Engineering (ICCSE 2018), Kuwait, 2018-03-11)This paper proposes a smart automated scheme to monitor and control various processes in oil refineries. The proposal aims to continuously collect data from oil tanks and pipelines, trigger alarm systems for any malfunction, ... -
A Systematic Approach to Model and Simulate Controlling Industrial Processes with Uncertainties
(The 11th Annual EEE Systems Conf. (SYSCON 2017), Montreal, Quebec, Canada, 2017-04-24)This paper investigates the design of adaptive controllers for such applications that could be modeled by low order dynamics with some parameters uncertainties. Some of the control applications that fall into this category ... -
Adaptive Estimation-Based Control for Uncertain Processes with Low Order Dynamics
(The 9th IEEE GCC Conference & Exhibition, Manama, Bahrain, May 6-9, 2) -
Automated Smart Solar Irrigation System
(Smart Cities Symposium (SCS18), Bahrain, 2018-04-22)This paper introduces an Automated Smart Solar Irrigation System (ASSIS) that avoids the disadvantages and limitations of existing traditional irrigation systems, mainly nonuniform distribution of water to all crops and ... -
Hybrid Sensing of Internal and Surface Partial Discharges in Air-Insulated Medium Voltage Switchgear
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-04)Partial discharge (PD) measurements have proved their reliability for health monitoring of insulation systems in power system components including synchronous generators, power transformers, switchgear and cables etc. ... -
Intelligent nonmodel-based fault diagnosis of electric motors using current signature analysis
(2019-11-24)This paper proposes an efficient technique for detecting mechanical faults in three-phase induction motors, without using mechanical sensors. Only measurements of the currents of every phase are used to identify the fault. ... -
Recursive Synchronization of the Unified Chaotic System Using a Single Time Series
(IEEE 59th International Midwest Symposium on Circuits and Systems (MWSCAS 2016), Abu Dhabi, UAE, 2016-10-16) -
Smart Oil Refinery - SOR
(The 9th Annual Undergraduate Research Conference on Applied Computing, Dubai, UAE, 2017-04-26) -
Suppressing Chaos in Uncertain Nonautonomous Oscillators
(2014-03-26)This paper investigates the control and suppression of chaos in nonautonomous oscillators with uncertain and/or unknown parameters. A nonlinear second order Duffing oscillator that has a single harmonic excitation and two ... -
Time-dependent generalization of the Nos-Hoover thermostatting technique for molecular dynamics simulations
(2014)The Nosé-Hoover scheme demonstrates that molecular dynamics simulations can be used to calculate the properties of systems at constant temperature (i.e. canonical ensemble averages). There is interest in deterministic ...
