Stability estimate for the semi-discrete linearized Benjamin-Bona-Mahony equation
(EDP Sciences, 2021)
In this work we study the semi-discrete linearized Benjamin-Bona-Mahony equation (BBM) which is a model for propagation of one-dimensional, unidirectional, small amplitude long waves in non-linear dispersive media. In ...
A Generalized Log-Normal Model for Grouped Survival Data
(Taylor & Francis Inc, 2010-01-01)
It is common to have experiments in which it is not possible to observe the exact lifetimes but only the interval where they occur. This sort of data presents a high number of ties and it is called grouped or interval-censored ...
Modelling and simulation of complex cellular models using Cell-DEVS
(SAGE Publications, 2016-02)
Cellular automata are discrete dynamical systems that provide a mathematical framework for modelling, studying and predicting the behaviour and response of systems across many different disciplines and domains, ranging ...
Direct discrete time design of robust state derivative feedback control laws
(2018-01-02)
This paper is concerned with the problem of designing robust state derivative feedback control laws in discrete time. The main contribution consists of a method for recasting a continuous time state space model in the form ...
A DISCRETIZATION SCHEME FOR AN ONE-DIMENSIONAL REACTION-DIFFUSION EQUATION WITH DELAY AND ITS DYNAMICS
(AMER INST MATHEMATICAL SCIENCES, 2009)
The goal of this paper is to present an approximation scheme for a reaction-diffusion equation with finite delay, which has been used as a model to study the evolution of a population with density distribution u, in such ...
A multivariate survival model induced by discrete frailty
(Taylor & Francis Inc, 2020-08-11)
Frailty models are generally used to model heterogeneity and dependence between individuals. The distribution of the frailty variable is often assumed to be continuous. However, there are situations where a discretely-distributed ...
Discrete modeling and experimental validation of the model of a cantilever flexible beam
(2015-04-01)
Cantilevered beams are studied in many ways because they are simple and largely applicable in many engineering problems. This study shows the development of a discrete dynamic model for a flexible cantilever beam and the ...
Continuum, Discrete, and Explicit Solvation Models for Describing the Low-Lying Absorption Spectrum of the Pterin Acid in Aqueous Environment
(JOHN WILEY & SONS INC, 2010)
The absorption spectrum of the acid form of pterin in water was investigated theoretically. Different procedures using continuum, discrete, and explicit models were used to include the solvation effect on the absorption ...
A method of discretization for the lagerström-cole model equation
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 2000)
A method of discretization for a non linear singularly perturbed boundary value problem is considered. It involves a certain number of steps, one of them including the application of Petrov-Galerkin finite element methods. ...
Likelihood approximations and discrete models for tied survival data
(Marcel Dekker Inc, 2002-01-01)
Ties among event times are often recorded in survival studies. For example, in a two week laboratory study where event times are measured in days, ties are very likely to occur. The proportional hazards model might be used ...
