Displacements induced by earthquake can be very large and result in severe damage to earth and earth supported structures including embankment dams, road embankments, excavations and retaining walls. It is important, therefore, to be able to predict such displacements. In this paper, a new approach to prediction of earthquake induced displacements of slopes (EIDS) using hybrid support vector re...
Vis-NIR spectroscopy has been introduced as a non-destructive, fast, and cheap technique, with minimal sample preparation and no loss or damage to the environment. No investigation has yet been carried out to examine the ability of this method to estimate soil properties in Iran. The objective of this research was to investigate the capability of Vis-NIR spectroscopy to predict the amount of or...
Background and purpose: Ultrasound is easily available, cheap, non-invasive and radiation-free that could be considered as an alternative to Dimercaptosuccinic Acid (DMSA) in evaluation of kidney damage. The aim of this study was to determine the prediction of kidney damage in ultrasound compared with DMSA (standard method) in children with pyelonephritis and vesicoureteral reflux. Materials a...
Background & Aim: Gestational diabetes could have harmful consequences on Children’s health. Since the initiation of gestational diabetes is simultaneous with brain evolution, this study is designed to predict evolutionary growth in children of mothers with gestational diabetes. Methods: In this study, the required data were obtained through investigating the profiles of pregnant women...
in this paper, a general elastoplastic-damage constitutive model considering the effect of strain rate has been developed. the derivation of this model has been cast into the irreversible thermodynamics with internal variables within the fundamentals of continuum damage mechanics (cdm). the rate effect has been involved as an additional term into the plastic yield surface (dynamic plastic yield...
This paper describes a finite element based method for simulating the effects of material removal, associated with fretting wear, on fretting fatigue parameters in a spline coupling. An incremental wear simulation technique is implemented with a single tooth finite element model of the coupling for symmetric loading, assuming equal wear on all teeth, using a comparatively coarse mesh model, for...
