Structural health monitoring is a developing research field which is multifunctional and can estimate the health condition of the structure by data analyzing and also can prognosticate the structural damages. Illuminating the damages by using piezoelectric sensors is one of the most effective techniques in structural health monitoring. Pressurized equipments are very important components in pro...

Sparsity constraints are now very popular to regularize inverse problems in the field of applied mathematics. Structural damage identification is a typical inverse problem of structural dynamics and Structural damage is a spatial sparse phenomenon, i.e., structural damage occurs, only part of elements or substructures are damaged. In this paper, a structural damage identification method based o...

1 Advanced signal processing approaches are widely used for nondestructive evaluation, structural health monitoring and damage detection. In this research, signals related to damage in a thin plate specimen were collected by piezoelectric wafer active sensors. Damage is detected and evaluated by using advanced signal processing approaches, including the short-time Fourier transform and the wave...

in an earthquake country like iran it is of paramount importance that the structural form be sound. the designer must be able to predict satisfactorily the behavior of the structure in the event of a strong ground motion. in order to be able to make a wise choice, he also should know enough about the consequences of the earthquake damage to the structure and economic factors involved. this pipe...

Quantifying the uncertainty in model parameters for the purpose of damage prognosis can be accomplished utilizing Bayesian inference and damage diagnosis techniques such as non-destructive evaluation or structural health monitoring. The number of samples required to solve the Bayesian inverse problem through common sampling techniques (e.g., Markov chain Monte Carlo) renders high-fidelity finit...

Traumatic brain injuries (TBI) are frequently caused by blasts which trigger a series of neuronal biochemical changes, often resulting in reduced brain/nervous system function and/or cell death. These blasts are characterized by two phases, an initial positive pressure phase closely followed by a negative pressure phase. Other possible blast aftereffects include stretching or shearing of the ce...

C ARDIAC INJURY commonly occurs in patients who sustain blunt thoracic trauma; the incidence in patients who survive transport to a hospital has been estimated at 10% to 20% depending on the diagnostic criteria used.‘-8 Most commonly, the injury is limited to myocardial contusion and the structural integrity of the heart remains intact.’ Although the signs and symptoms of significant cardiac st...

When structures are subjected to strong ground motion excitations, structural elements may be prone to yielding, and consequently experience significant levels of inelastic behavior. The effects of inelastic behavior on the distribution of peak floor loads are not explicitly accounted for in current seismic code procedures. During recent years, many studies have been conducted to develop new de...

conclusions with growing cohort of young and middle-aged people, there is a probable risk of upsurge of ard. presently, there are dilemmas over the diagnosis of independent ard. thus, there is a need to develop evidence-based guidelines for diagnosis and management of ard through further systematic studies. results the prolonged and excessive use of alcohol may lead to structural and functional...
