We study the thermodynamic behavior of the random chain model proposed by Iori, Marinari and Parisi, and how this depends on the actual sequence of interactions along the chain. The properties of randomly chosen sequences are compared to those of designed ones, obtained through a simulated annealing procedure in sequence space. We show that the transition to the folded phase takes place at a sm...

A simulated annealing algorithm is used in the construction of subsquare free Latin squares. The algorithm is described and experience from its application is reported. Results obtained include the construction of subsquare free Latin squares of orders 16 and 18, the smallest orders for which existence of such squares was previously in doubt.

A tensile sample of an Al-0.1Mg alloy was in-situ tested in a SEM followed by insitu annealing to develop recrystallizing nuclei/grains. The evolution of microstructure and crystallographic orientations were characterized using the EBSD technique. Changes in the same area within the sample during deformation and annealing steps were closely followed. During the deformation process the original ...

The web newspaper pagination problem consists in optimizing the layout of a set of articles extracted from several web newspapers and sending it to the user as the result of a previous query. This layout should be as similar as possible to that of real newspapers and should be adapted to the user's web browser con®guration in real time. Previous approaches to the problem took rather a long time...

This research comprises a study of the effect of heat treatment on fatigue behavior of (A193-51T-B7) alloy steel. Two heat treatment processes were conducted, namely, annealing and quenching followed by tempering at 200C. All fatigue tests were carried out using a rotary bending machine with constant stress ratio, R=-1. The eddy current probe was used to measure the crack length propagation. Fr...
