Dissipative Hamiltonian (DH) systems are an important concept in energy based modeling of dynamical systems. One of the major advantages of the DH formulation is that system properties are encoded in an algebraic way. For instance, the algebraic structure of DH systems guarantees
Stability radii for real linear Hamiltonian systems with perturbed dissipation
We study linear dissipative Hamiltonian (DH) systems with real constant coefficients that arise in energy based modeling of dynamical systems. In this paper we analyze when such a system is on the boundary of the region of asymptotic stability, i.e., when it has purely imaginary
Theoretical investigations on the vibronic coupling effect and NBO Studies of Stability on the GeX2 (X=F, Cl, and Br) molecules
The contemporary paper refers back to the instability of linear in GeX2 (X=F, Cl & Br) molecules because of the vibronic coupling effect. Optimization and the following frequency calculations in those molecules found out that every one of those molecules were unstable in high sym
A Fractional-in-Time Prey–Predator Model with Hunting Cooperation: Qualitative Analysis, Stability and Numerical Approximations
A prey–predator system with logistic growth of prey and hunting cooperation predators is studied. The introduction fractional time derivatives the related persistent memory strongly characterize model behavior, as many dynamical systems in applied sciences are well described by s
Sensitivity analysis of Typhoid Fever model with Saturated Incidence rate.
In this study, a dynamic model for typhoid fever incorporating protection against infection in the presence of saturated incidence rate is proposed. The existence and uniqueness solution is proved in order to ascertain the existence of the model. Stability analysis of endemic and
Nonlinear dynamical model of Costas loop and an approach to the analysis of its stability in the large
The analysis of the stability and numerical simulation of Costas loop circuits for highfrequency signals is a challenging task. The problem lies in the fact that it is necessary to simultaneously observe very fast time scale of the input signals and slow time scale of phase diffe
An Introduction to the Special Issue on Time Delay Systems: Modelling, Identification, Stability, Control and Applications
The special Issue “Time Delay Systems: Modelling, Identification, Stability, Control and Applications” intents to collect high-erudite papers aiming theoretical and/or practical matters dealing with time delay systems. In feedback control systems, delay as a generic part of many
On the continuous-time Takagi-Sugeno fuzzy systems stability analysis
In this paper, a new approach for the stability analysis of continuous-time Takagi–Sugeno (T-S) fuzzy system is proposed. The universe set is divided to subregions, and piecewise quadratic Lyapunov function is then found for each of them. This class of Lyapunov function candidate
Stability and dispersion analysis of improved time discretization for simply supported prestressed Timoshenko systems. Application to the stiff piano string
We study the implicit time discretization of piano strings governing equations within the Timoshenko prestressed beam model. Such model features two different waves, namely the flexural and shear waves, that propagate with very different velocities. We present a novel implicit ti
Application of risk analysis and assessment in tunnel design
A new risk analysis system for estimating the risk factors in tunneling is suggested in consideration of the complex effect in tunnel construction. It is verified that various risk factors can be expressed by stability and environment index using numerical and statistical analysi
