A hardware attack that enables the attacker to alter the main circuit with malicious hardware during either design or the fabrication process is studied and analyzed. This attack, known as the hardware Trojan, has different objectives such as destroying hardware, changing circuit characteristics or extracting sensitive information. So hardware Trojan detection and hardware security are critical...
The circle map is a general non-linear iterated function that maps the circle onto itself. In its standard form it can be interpreted as a simple sinusoidal oscillator which is perturbed by a non-linear term. By varying the strength of the non-linear contribution a rich array of non-linear responses can be achieved, including waveshaping, pitch-bending, period-doubling and highly irregular patt...
We take a new approach to investigate synchronization in networks of coupled oscillators. We show that the coupled oscillator system when restricted to a proper region is a distributed partial primal-dual gradient algorithm for solving a well-defined convex optimization problem and its dual. We characterize conditions for synchronization solution of the KKT system of the optimization problem, b...
Time}frequency study of oscillation build-up in an electrostatic accelerator free-electron laser (EA-FEL) oscillator is presented. The unique features of EA-FEL and its capacity to operate in a long pulse mode, enable observation and study of linear and non-linear processes taking place in the evolution of radiation in the EA-FEL oscillator. The experimental data recorded with the aid of a digi...
In this work, we study the Kuramoto model on scale-free, random and small-world networks with bimodal intrinsic frequency distributions. We consider two models: in one of them, the coupling constant of the ith oscillator is independent of the number of oscillators with which the oscillator interacts, and in the other one the coupling constant is renormalized with the number of oscillators with ...
It is shown that the nonlinear pendulum equation can be transformed into a linear harmonic oscillator in phase space thanks to Kerner’s method [12]. Moreover, as mathematical divertissement, ...
The predictor-corrector methods P (EC) with equidistant discretization are applied to the numerical integration of a linear stochastic oscillator. Their ability in preserving the symplecticity, the linear growth property of the second moment, and the oscillation property of the solution of this stochastic system is studied. Their mean-square orders of convergence are discussed. Numerical experi...
The relativistic harmonic oscillator is one of the most important quantum system, as it is one of the very few that can be solved exactly. The Dirac relativistic oscillator (DO) interaction is an important potential both for theory and application. It was for the first time studied by Ito et al [1]. They considered a Dirac equation in which the momentum p is replaced by p − imβω r, with r being...
The classical quantization of a Lienard-type nonlinear oscillator is achieved by scheme (M. C. Nucci. Theor. Math. Phys., 168:994–1001, 2011) that preserves the Noether point symmetries underlying Lagrangian in order to construct Schrodinger equation. This method straightforwardly yields equation momentum space as given (V. Chithiika Ruby, M. Senthilvelan, and Lakshmanan. J. Phys. A: Gen., 45:3...
A well-designed free-running oscillator provides a periodic signal of constant amplitude and frequency fo from the energy delivered by direct-current (dc) sources. This has an immediate application for the realization of local oscillators used in the frequency-conversion stages of communication systems [1]. In receivers, the modulated signal at radio-frequency (RF) fRF is mixed with the output ...
