On Inverse Full State Hybrid Function Projective Synchronization For Continuous-time Chaotic Dynamical Systems with Arbitrary Dimensions
Referring to continuous-time chaotic dynamical systems, this paper investigates the inverse full state hybrid function projective synchronization (IFSHFPS) of non-identical systems characterized by different dimensions. By taking a master system of dimension n and a slave system of dimension m, the method enables each master system state to be synchronized with a linear combination of slave system
Comparative Study of CNTFET Implementations of 1-trit Multiplier
Ternary logic has become a promising alternative to traditional binary logic due to low power consumption and reduced circuits such as interconnects and chip areas. The efficiency of the multiplier circuit can be much better using a ternary logic system. Carbon nanotube field-effect transistor (CNTFET) is a promising technology as it achieves more advantages than MOSFET due to its low off-current
On Flashing over the Air 'FOTA' for IoT Appliances - An ATMEL Prototype
Wireless flashing over the air is a challenging task. Appliances are required to update its flash or EEPROM via a remote system update. However, direct connectivity via a wire is not available. Within the application of consumer electronics, such as utility meters or other appliances, there is always a room to update the appliance remotely for optimal operation. In this paper, we present a new
Do the Bio-impedance Models Exhibit Pinched Hysteresis?
Recently, pinched hysteresis has been found in the electrical modelling of regular plant tissues. Usually, the biological tissues are characterized in the frequency domain using bio-impedance analyzers without investigating the time domain, which would show the pinched hysteresis. In this paper, the current-voltage analysis of some of the widely known electrical bio-impedance models is studied
Online teaching at Egyptian private universities during COVID 19: Lessons learned
The aim of this empirical article is identifying and showing the key challenges and core problems faced by private universities with international affiliation, located in west Cairo, when applying online educational learning in the context of COVID-19. As well, it aims to assist in assembling the lessons learned to maximize the learning impact. a mixed-methods approach was used and it included: (1
A 26.24uW 9.26-ENOB Dynamic RAM Based SAR ADC for Biomedical Applications
This work introduces a new successive approximation register circuit (SAR) for SAR analog to digital converter (ADC) based on Dynamic Random Access Memory (DRAM) cells. Based on the proposed DRAM based SAR ADC and a differential capacitive DAC, a 10-bit 2V ADC is designed in 0.18um CMOS technology. The proposed SAR is compared to traditional SAR to verify that the proposed SAR decreases the power
Almost Entirely Empirical Estimation for Chemical Potential
Abstract: Based on statistical thermal approaches, the transverse momentum distribution of the well-identified produced particles, π+, π–, K+, K–, p, and (Fromula presented.), is studied. We aim at introducing a novel almost entirely empirical estimation for the inclusive chemical potential μ. From the partition function of a grand-canonical ensemble, we propose a generic expression for the
Fractional calculus definitions, approximations, and engineering applications
The basic idea behind fractional calculus is that it considers derivatives and integrals of non-integer orders giving extra degrees of freedom and tuning knobs for modeling complex and memory dependent systems with compact descriptions. This paper reviews fractional calculus history, theory, and its applications in electrical engineering. The basic definitions of fractional calculus are presented
A novel image encryption system merging fractional-order edge detection and generalized chaotic maps
This paper presents a novel lossless image encryption algorithm based on edge detection and generalized chaotic maps for key generation. Generalized chaotic maps, including the fractional-order, the delayed, and the Double-Humped logistic maps, are used to design the pseudo-random number key generator. The generalization parameters add extra degrees of freedom to the system and increase the
Fractional-order Memristor Emulator with Multiple Pinched Points
The paper proposes voltage-controlled first-and second-order memristor emulators. The emulators are designed using an operational-transconductance amplifier (OTA) and voltage multiplier blocks plus a fractional-order capacitor. The presented second-order emulator provides two pinched points controlled by order of the employed fractional-order capacitor. Numerical and PSPICE simulation results
