This work present the use of a neural structure to augment the quality of noisy images of liquid bridges to obtain a clear representation of its border in order to determine the acceleration that it is suffering. The used network is a three layers Discrete Time Cellular Neural Network in which the last one performs the contour highlighting through the adaptive definition of the gain and thresho...

ESR studies of chain motion in 4,4'-dioctadecyloxyazoxybenzene are reported. The specially synthesised spin labels, closely resembling the host molecule, were marked at different positions along the chain. The results show that the solid* SB transition is accompanied by a melting of the chains. A consideration of the calorimetric data for a number of similar compounds suggests that chain meltin...

This Letter reports experimental results on the coalescence of two liquid drops driven by surface tension. Using a high speed imaging system, we studied the early-time evolution of the liquid bridge that is formed upon the initial contact of two liquid drops in air. Experimental results confirmed the scaling law that was proposed by Eggers et al. based on a simple and yet elegant physical argum...
