In this paper we study the approximate controllability of control systems with states and controls in Hilbert spaces, and described by a second-order semilinear abstract functional differential equation with infinite delay. ...

In this article, the fuzzy Lyapunov function approach is considered for stabilising continuous-time Takagi-Sugeno fuzzy systems. Previous linear matrix inequality (LMI) stability conditions are relaxed by exploring further ...

This paper proposes a text-based systemic-functional account of the Spanish nominal group. Firstly, approaching the Spanish nominal group 'from above' (i.e. taking the contextual variables of field and mode as a starting ...

New local functionals for the kinetic and Hartree-Fock exchange energy of atoms are proposed. They are of the following general form: T[ρ] =22/3CF ∫ ∑σρ5/3 σf(r,ρ σ)dr. The function f(r,ρσ), except for two adjustable ...

The problem of power system stability including the effects of a flexible alternating current transmission system (FACTS) is approached. First, the controlled series compensation is considered in the machine against infinite ...

Impulse response functions (IRFs) and frequency response functions (FRFs) are fundamental quantities that describe the dynamic behaviour of a linear vibrating system in the time and frequency domains respectively. The ...
