NQR parameters of complexes and polarizability effect

Magnetic Resonance in Chemistry, 2012
The literature data on substituent influence on the nuclear quadrupole resonance frequencies (ν), quadrupole coupling constants (e2Qq ⋅ h− 1), and asymmetry parameters (η) for 36 series of the H‐complexes, charge–transfer complexes, transition metal complexes and other donor–acceptor complexes have been considered, using the correlation analysis ...

Parameter identification of complex network dynamics

Nonlinear Dynamics, 2021
Here, we present a novel approach called the “parameter identification of complex network dynamics” algorithm which combines elements of the sparse identification of nonlinear dynamics algorithm with a genetic algorithm to automatically and efficiently discover the underlying dynamics of complex networks from data with minimal domain-specific knowledge

Fixed-parameter complexity and cryptography

1993
We discuss the issue of the parameterized computational complexity of a number of problems of interest in cryptography. We show that the problem of determining whether an n-digit number has a prime divisor less than or equal to nk can be solved in expected time f(k)n3 by a randomized algorithm that employs elliptic curve factorization techniques (this ...

ON PARAMETER IDENTIFICATION FOR COMPLEX BIOTECHNICAL SYSTEMS

IFAC Proceedings Volumes, 1985
The parameter identification problem is treated for an SCP process in a tower loop bioreactor (fed batch process). The emphasis is laid on the sensors needed for proper identification of the unknown four parameters in the given model. In particular the following three questions are solved: a)Which types of measurements must be used (dissolved oxygen in

Determination of model parameters from complex spectra

Physica Status Solidi (a), 1981
An evaluation procedure for the determination of model parameters from complex spectra is derived. The spectra are assumed to be composed of similar individual curves of known shape. The algorithm takes account of the scatter of the measurement. Es wird ein Verfahren zur Ermittlung der Modellparameter komplexer Spektren abgeleitet.

Parameter Estimation for Distributed Parameter Models of Complex, Flexible Structures

IFAC Proceedings Volumes, 1991
Distributed parameter modeling of structural dynamics has been limited to simple spacecraft configurations because of the difficulty of handling several distributed parameter systems linked at their boundaries. Although there is other computer software able to generate such models or complex, flexible spacecraft, unfortunately, neither is suitable for ...
