This paper outlines the application of the multi-layer perceptron artificial neural network (ANN), ordinary kriging (OK), and inverse distance weighting (IDW) models in the estimation of local scour depth around bridge piers. As part of this study, bridge piers were installed with bed sills at the bed of an experimental flume. Experimental tests were conducted under different flow conditions an...

The expansion of logistics requirements, limited space and strict requirements generators requests (GLR) in terms service quality complicate the supply region, resulting necessity to improve models (MoL). Proximity water, presence ports piers along coast, new eco vehicles development cooperation between land water transport are elements for improving existing MoLs an economically environmentall...

Extensive numerical and analytical studies exist that focus on the scours around bridge piers with different cross-sections. However, addressing scour piles are rather limited not conclusive. Therefore, most efficient cross-section reducing local a pile group is experimentally examined herein. Accordingly, comparative scouring of three shapes, namely, circular, rectangular lenticular, investiga...

The Coastal area of Nazhvan is located at the riverside of Zayandehrūd River in the western part of Isfahan. In the gardens of this area which are mostly orchards, woodlands full of fruitless trees, owners have constructed architectural spaces and pavilions. One of the prominent architectural spaces within this territory is a mill known as “Asyāb-e Nazhvān or Hājjī”. There stands a two-floor pa...

BACKGROUND Children suffering from thalassemia have higher levels of depression and lower levels of self-concept. OBJECTIVES The aim of this study was to determine if group play therapy could significantly increase self-concept among children with thalassemia major ages 7 to 11 years old in teaching hospitals of Golestan province, Iran, in 2012. PATIENTS AND METHODS In this randomized, cont...

A finite element model has been developed to simulate nonlinear response of piles/drilled piers under axial loading. The nonlinear stress-strain behaviors of soils are modeled via Drucker-Prager and von Mises type plasticity. A parametric study is carried out to address the influence of various factors, such as soil friction approximation, dilatancy, effect of interface element and shear streng...
