Multifractal analysis has been used to diagnoze cracked and healthy rotors. Is has been shown that the complexity and regularity criteria of the dynamical systems defined by the multiple scaling of the time series can indicate the damages of the rotating shaft.

A bezoar is a gastrointestinal mass developed via the accumulation and hardening of undigested or partially digested materials within the digestive tract. While often seen in the stomach, bezoars are rarely observed in the colon. Although many studies have reported that whole-grain foods have a positive effect on intestinal functions because of their high fiber content,1 a very limited number o...

Cracking is one of the most severe problems facing the concrete industry worldwide. Of critical importance is the drastic decline of durability associated with these cracks, and the resulting cost of repair or replacement of concrete structures. This research examines the effect of crack width and crack frequency upon the durability of reinforced mortar, quantified by water permeability. Crack ...

Autonomous vehicles will not be driven by a human being. The missing of the human being will make the vehicles less inspected because a human being often listens to the engine and its sounds. A passenger in an autonomous vehicle usually does other things and even sleeps, so the human inspection on the engine and on the pipes system will not be effective. This paper suggests a system that alerts...

An elastic-plastic analysis is performed for two problems relevant to fracture mechanics: a semi­ infinite body with an edge crack in a far out-of-plane shearing field and an infinite plate under plane stress conditions containing a finite line crack in a remote tensile field. Amplitudes of the dominant singularity in the plastic region at the crack tip, the plastic stress and strain intensity ...

An informal argument shows that common knowledge of rationality implies the iterative elimination of strongly dominated strategies. Rationality here means that players do not play strategies that are strongly dominated relative to their knowledge. We formalize and prove this claim. When by rationality we mean that players do not play strategies that are weakly dominated relative to their knowle...

structural health monitoring of cracked structures is one of beloved subject of researchers recently. consider of crack behavior in the water and energy pipeline is important because of environmental problems. in this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. for this purpose, three- dimensional parametric model of cracked ...

Correctly determining the onset of fracture is crucial when performing mechanical experiments. Commonly carried out by visual inspection, here an image-based machine learning approach proposed to classify cracked and un-cracked specimens. It yields potential objectify automate crack detection, thereby removing sources uncertainty error from post-processing More than 30’000 speckle-pattern image...
