Gaussian process model based predictive control [PDF]

open access: yes, 2004
Gaussian process models provide a probabilistic non-parametric modelling approach for black-box identification of non-linear dynamic systems. The Gaussian processes can highlight areas of the input space where prediction quality is poor, due to the lack ...

Warped Gaussian process modelling of transcriptional regulation [PDF]

open access: yes, 2012
This article extends recent work on Gaussian process modelling of transcriptional regulation, which assumed additive Gaussian noise of constant variance, to heteroscedastic noise.

Variational Bayesian multinomial probit regression with Gaussian process priors [PDF]

open access: yes, 2006
It is well known in the statistics literature that augmenting binary and polychotomous response models with Gaussian latent variables enables exact Bayesian analysis via Gibbs sampling from the parameter posterior.

FT-IR Spectroscopic Studies and Gaussian 03 Calculations of 2, 2'-Ethylenebis(nitrilomethylidene)diphenol

open access: yesOriental Journal Of Chemistry, 2012
The vibrational wavenumbers and corresponding vibrational assignments of 2,2'-Ethylene bis(nitrilomethylidene) diphenol are examined theoretically using the Gaussian03 set of quantum chemistry codes. Comparison of the observed IR spectra with the calculated results by HartreeFock and B 3 lyp method is found in agreement with the experimental data ...

DFT Calculation on 76 Polychlorophenazines: Their Thermodynamic Function and Implication of Cl Substituted Position

open access: yesInternational Journal of Chemical Engineering, 2008
Thermodynamic functions, including enthalpy (Hθ) and entropy (Sθ) for 76 polychlorophenazines (PCPZs) in the gas state at 298.15 K and 101.325 kPa, have been calculated using the B3LYP/6-31G∗ level with Gaussian 03 program, and considered on solvation ...

An improved solvent-free synthesis of flunixin and 2-(arylamino) nicotinic acid derivatives using boric acid as catalyst

open access: yesChemistry Central Journal, 2017
A simple solvent-free protocol for the preparation of flunixin, a potent non-narcotic, non-steroidal anti-inflammatory drugs is reported using boric acid as catalyst. Its salt, flunixin meglumine are then prepared under reflux in EtOH.

Energetic Di- and Trinitromethylpyridines: Synthesis and Characterization

open access: yesMolecules, 2017
Pyridine derivatives based on the addition of trinitromethyl functional groups were synthesized by the reaction of N2O4 with the corresponding pyridinecarboxaldoximes, then they were converted into dinitromethylide hydrazinium salts.
