Controllability of the linear elasticity as a first-order system using a stabilized space-time mixed formulation

open access: yes, 2022
International audienceThe aim of this paper is to study the boundary controllability of the linear elasticity system as a first-order system in both space and time. Using the observability inequality known for the usual second-order elasticity system, we

Exponential Attractor for a First-Order Dissipative Lattice Dynamical System

open access: yesJournal of Applied Mathematics, 2008
We construct an exponential attractor for a first-order dissipative lattice dynamical system arising from spatial discretization of reaction-diffusion equations in ℝ𝑘. And we obtain fractal dimension of the exponential attractor.

Controllability of semilinear systems with fixed delay in control [PDF]

open access: yesOpuscula Mathematica, 2015
In this paper, different sufficient conditions for exact controllability of semilinear systems with a single constant point delay in control are established in infinite dimensional space. The existence and uniqueness of mild solution is also proved under

Closed-Form Equation of Data Dependent Jitter in First Order Low Pass System

open access: yesThe Scientific World Journal, 2014
This paper presents a closed-form equation of data dependent jitter (DDJ) in first order low pass systems. The DDJ relates to the system bandwidth, the bit rate, the input rise/fall time, and the number of maximum consecutive identical bits of the data ...

On the Fundamental Analyses of Solutions to Nonlinear Integro-Differential Equations of the Second Order

open access: yesMathematics, 2022
In this article, a scalar nonlinear integro-differential equation of second order and a non-linear system of integro-differential equations with infinite delays are considered.

First-Order Interpolation and Interpolating Proof Systems

open access: yesEPiC Series in Computing, 2018
It is known that one can extract Craig interpolants from so-called localproofs. An interpolant extracted from such a proof is a booleancombination of formulas occurring in the proof. However, standard completeproof systems, such as superposition, for theories having the interpolationproperty are not necessarily complete for local proofs: there are ...

First-order system least squares with inhomogeneous boundary conditions

open access: yes, 2013
We derive well-posed first-order system least-squares formulations of second-order elliptic boundary value problems, in which homogeneous essential boundary conditions are appended by means of additional equations, rather than by their incorporation in ...
