In this study, an artificial neural networkbased Bayesian regularization (ANN) model is proposed to predict the compressive strength of concrete. The database in this study includes 208 experimental results synthesized from laboratory experiments with 9 input variables related to temperature change and design material composition.

The results of ultrasonic wave propagation experiments indicated that the presence of steel fibers at a 2% content increased the time of wave propagation. On the other hand, curing conditions, specimen maintenance time, and transmission path distance affected the ultrasonic wave propagation time in high-strength concrete.

This paper presents the free vibration analysis of stiffened isotropic plate by means of finite element method. Stiffeners are used in plates to increase the strength and stiffness. The effect of position of stiffeners on isotropic plate has been studied which involve the possible combination of clamped and free edge condition.

A defensive alliance in a graph G = (V,E) is a set of vertices S V satisfying the condition that for every vertex v 2 S, the number of neighbors v has in S plus one (counting v) is at least as large as the number of neighbors it has in V − S. Because of such an alliance, the vertices in S, agreeing to mutually support each other, have the strength of numbers to be able to defend themselves from the vertices in V − S. A defensive alliance S is called global if it effects every vertex in V − S, that is,...
