On state representations of time-varying nonlinear systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This work considers a nonlinear time-varying system described by a state representation, with input u and state x. A given set of functions v, which is not necessarily the original input u of the system, is the (new) input ...
Existence Results for Second Order Differential Equations with Nonlocal Conditions in Banach Spaces
(KOBE UNIV, DEPT MATHEMATICS, 2009)
This work is concerned with implicit second order abstract differential equations with nonlocal conditions. Assuming that the involved operators satisfy sonic compactness properties, we establish the existence of local ...

On the Boundedness of Solutions of Discontinuous Differential Equations
(Sociedade Brasileira de Matemática Aplicada e Computacional - SBMAC, 2021-09-06)
By using the notion of Carathéodory solution to differential equations, the present work studies the boundedness of solutions of discontinuous differential equations. For these discontinuous systems determined by discontinuous ...
Experimental Analysis of Differential Pairs Designed with Line Tunnel FET Devices
(Ieee, 2017-01-01)
The aim of this work is to study, for the first time, the behavior of differential pair circuits designed with Line TFETs and compare the suitability of this technology with alternatives such as FinFETs and Point TFETs. ...

The aim of this work is to study, for the first time, the behavior of differential pair circuits designed with Line TFETs and compare the suitability of this technology with alternatives such as FinFETs and Point TFETs. ...
Some remarks on static-feedback linearization for time-varying systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This work summarizes some results about static state feedback linearization for time-varying systems. Three different necessary and sufficient conditions are stated in this paper. The first condition is the one by [Sluis, ...
Equações diferenciais lineares sem solução
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2014-02-27)
In this work we present the proof of a result due to Lars Hörmander which establishes a necessary condition for a linear operator with variable coefficients is globally resolvable.
Discontinuous almost periodic type functions, almost automorphy of solutions of differential equations with discontinuous delay and applications
(University of Szeged, 2014)
Abstract. In this work, using discontinuous almost periodic type functions, exponential dichotomy and the notion of Bi-almost automorphicity we give sufficient conditions to obtain a unique almost automorphic solution of ...
Interactive Fuzzy Fractional Differential Equation: Application on HIV Dynamics
(2020-01-01)
This work presents an application of interactive fuzzy fractional differential equation, with Caputo derivative, to an HIV model for seropositive individuals under antiretroviral treatment. The initial condition of the ...
