Nonlinear Phase Adjustment of Selective Excitation Pulses
Journal of Magnetic Resonance, 2000A continuous transformation of an RF waveform with a modified Korteweg-de Vries equation or generalization can be used to adjust the phase behavior of a selective excitation pulse while preserving the magnitude behavior of the spin response. This transformation has applications in removing or adding to the nonlinear phase properties of a selected ...

An Analysis of Nonlinear Acceleration Coefficients Adjustment for PSO
2012Linear acceleration coefficients adjustment had been widely used in particle swarm optimization (PSO). In this paper, a novel nonlinear strategy is developed, where the acceleration coefficients including both cognitive component and social component are adjusted nonlinearly to improve the optimization performance within a reasonable iteration times ...

LEVERAGE ADJUSTMENTS FOR DISPERSION MODELLING IN GENERALIZED NONLINEAR MODELS
Australian & New Zealand Journal of Statistics, 2009SummaryFor normal linear models, it is generally accepted that residual maximum likelihood estimation is appropriate when covariance components require estimation. This paper considers generalized linear models in which both the mean and the dispersion are allowed to depend on unknown parameters and on covariates.

Transients in the Nonlinear Adjustment to Geostrophy
1990The consequences of nonlinearity on the character of the waves generated during the adjustment to geostrophic equilibrium of a layer of incompressible fluid are investigated by comparing the results of a linear analysis to the approximate solution to the full nonlinear problem obtained numerically.

Nonlinear Element Compensation by Gain Adjustment and Dither Smoothing
2007 IEEE 22nd International Symposium on Intelligent Control, 2007A novel approach to linearize nonlinearities commonly inherent in actuators is proposed in this paper. This approach solves the inverse of the nonlinearity without requiring its I/O relations as a one-on-one map, which is necessary for the current inverse-model method By introducing the concept of the equivalent gain, the proposed method systematically

Evaluation of the Effect of Nonlinear Kinetics on Dosage Adjustments of Theophylline
Therapeutic Drug Monitoring, 1983The pharmacokinetics of theophylline at two different dosage levels were studied in six adult volunteers. The subjects were allowed to reach steady-state serum concentrations of theophylline after 7 days of administration of a sustained-release oral product.

Improved Z-scan adjustment to thermal nonlinearities by including nonlinear absorption
Optics Communications, 2017Abstract We propose a modified mathematical model of thermal optical nonlinearities which allow us to obtain the nonlinear refraction index and the nonlinear absorption coefficient with only one measurement. This modification is motivated by the influence that nonlinear absorption has on the measurement of the nonlinear refraction index at far field,

Delay Adjusted Noise Effect in Coupled Nonlinear Chemical System
2008 The 9th International Conference for Young Computer Scientists, 2008The counterintuitive noise effect in nonlinear systems plays an important role in determining the system dynamics near the bifurcation point. In many systems whose information processing is based on the spatiotemporal dynamics, delay in the information transition process is also important.

Nonlinear control and state space adjustments
UKACC International Conference on Control (CONTROL '98), 1998In the literature some techniques traditionally used in the study of the existence of solutions of nonlinear differential equations have been extended to solve problems of control, state estimation and parameter identification of nonlinear systems.

Nonlinear Parametric Least-Squares Adjustment.
1987Abstract : A parametric adjustment model expresses n observables in terms of u parameters, where the structure linking the two groups is in general nonlinear. This model can be expanded in the Taylor series based on an initial point P. The standards procedure includes only the linear terms, constituting a known linearized model at P which is resolved ...
