*H and H NMR Studies of Mixtures 2,6-Lutidine/Water Near the Lower Critical Solution Point

Deuteron spin-lattice relaxation time (TJ measurements of binary mixtures 2,6-lut idine/D20 have been done near the lower critical solution point (Tc L), e = (T — Tg L)/Tc 10~. Singularities are observed at Tc L . The changes in the slope of Ti (H) = / ( T ) can be interpreted as due to the effect of concentration changes on Ty and simultaneously strong overlaping of H N M R signals from coexis...

On the Critical Points of Gaussian Mixtures by Benjamin Wallace

This thesis is concerned with studying the question whether or not Gaussian mixtures have finitely many critical points. The relevance of this problem to the convergence of the meanshift algorithm is discussed and an overview of some basic properties of the critical points of Gaussian mixtures is provided. Some previous results that are then reviewed include a reduction of this problem in the h...

Unbounded Critical Points for a Class of Lower Semicontinuous Functionals

In this paper we prove existence and multiplicity results of unbounded critical points for a general class of weakly lower semicontinuous functionals. We will apply a nonsmooth critical point theory developed in [10, 12, 13] and applied in [8, 9, 20] to treat the case of continuous functionals.

Analysis of Ultrasonic Velocities in Hydrocarbon Mixtures

Ultrasonic velocity data on hydrocarbon mixtures was shown by Wang and Nur [JASA 89, 2725 (1991)] to agree quite well with the predictions of a simple mixing rule (volume average of velocity). The same data is reanalyzed using Wood's formula and the time average approximation. Wood's formula for acoustic velocity is shown to be always less than the time average formula, which is itself always l...

Surface Tension Prediction of Hydrocarbon Mixtures Using Artificial Neural Network

In this study, artificial neural network was used to predict the surface tension of 20 hydrocarbon mixtures. Experimental data was divided into two parts (70% for training and 30% for testing). Optimal configuration of the network was obtained with minimization of prediction error on testing data. The accuracy of our proposed model was compared with four well-known empirical equations. The arti...
