Oscillatory behavior in linear difference equations under unmodeled dynamics and parametrical errors
(Hindawi Publishing Corporation, 2007)
This paper investigates the presence of oscillating solutions in time-varying difference equations even in the case when there exist parametrical errors (i.e., errors in the sequences defining their coefficients) and/or ...
On the properties of reachability, observability, controllability, and constructibility of discrete-time positive time-invariant linear systems with aperiodic choice of the sampling instants
(Hindawi Publishing Corporation, 2007)
This paper investigates the properties of reachability, observability, controllability, and constructibility of positive discrete-time linear time-invariant dynamic systems when the sampling instants are chosen aperiodically. ...
About K-Positivity Properties of Time-Invariant Linear Systems Subject to Point Delays
(Hindawi Publishing Corporation, 2007)
This paper discusses nonnegativity and positivity concepts and related properties for the state and output trajectory solutions of dynamic linear time-invariant systems described by functional differential equations subject ...
Quantum size effects of Pb overlayers at high coverages.
(Elsevier, 2007-07-18)
We have studied Pb thin films as a function of the thickness up to 60 monolayers (MLs) using ab initio first principles and model calculations. Magic heights corresponding to a modulated oscillatory pattern of the energy ...
