In this paper we develop a growth process for obtaining flat and relaxed In0.2Ga0.8As layers on GaAs (001). The process designed is based on the results obtained by in situ and real time characterization of surface morphology and layer relaxation. In particular our results show that for growth temperatures Ts ≤ 200 oC, the relaxation of In0.2Ga0.8As layers is inhibited and the morphology does n...

Relaxation labeling algorithms introduced by Rosenfeld et al., have been widely used in image and sequence matching applications. The underlying mechanism of labeling via relaxation is a deterministic dynamical system whose initial status converges to one of the attractors. This is also a process of the input image segments being assigned the predetermined labels in a parallel and unsupervised ...

This paper addresses a major problem in pattern recognition: the unambiguous identification of objects. Comparing the characteristics of objects with the characteristics of possible interpretations, the identification of objects is frequently ambiguous. To reduce ambiguous assignments one can include a) more characteristics or b) contextual information into the identification. We use contextual...

The deformation of metallic glasses involves two competing processes: a disordering process involving dilatation, free volume accumulation, and softening, and a relaxation process involving diffusional ordering and densification. For metallic glasses at room temperature and under uniaxial loading, disordering usually dominates, and the glass can fail catastrophically as the softening process ru...

the molecular weight distribution of 4 commercial isotactic polypropylene (ipp) samples was estimated using rheological data. the dynamic moduli data, obtained from rheological measurements in linear viscoelastic region was used for calculation of relaxation time spectrum, h(τ) and then shear relaxation modulus, g(t). finally, applying thimm kernel function and relaxation modulus data in genera...
