Abstract   In this study, generalized differential quadrature analysis of elastic/plastic buckling of skew thin plates is presented. The governing equations are derived for the first time based on the incremental and ...

The mathematical modeling of a gas network is a powerful tool in order to identify the behavior of system under the different conditions. The modeling can be performed both for the steady state and unsteady state conditions. ...

This paper focuses on effect of abrasion process on color and reflectance factor changes of dyed woven fabrics containing 100% acrylic chenille yarns in weft and cotton warp yarns. Three fabrics having 12, 14 and 16 weft ...

The possibility of using flat plate collector in northern parts of Iran specially city of Rasht has been investigated in this paper. According to the high humidity in the northern parts of this country, diffuse radiation ...

Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN ...

Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. ...

The necessity for decrease in consumption of conventional fuel, related energy and to promote the use of renewable sources such as biofuels, demands for the effective evaluation of the performance of engines based on laws ...

An experimental investigation was carried out to study mixed convection heat transfer from Al2O3-water nanofluid inside a vertical, W-shaped, copper-tube with uniform wall temperature. The tests covered different ranges ...

We consider competition between two decentralized supply chains network under demand uncertainty. Each chain consists of one risk-averse manufacturer and a group of risk-averse retailers. These two chains present substitutable ...

This paper proposes a mixed integer programming model for single-item capacitated lot-sizing problem with setup times, safety stock, demand shortages, outsourcing and inventory capacity. Due to the complexity of problem, ...

The decision making on selection of improvement solutions was one of the obstacles hampering the success of process improvement. This paper presents the House of Improvement (HOI) model as a guideline to link decision ...

Strategic planning in each organization identifies its orientation and coming priorities as all decisions to be adopted respect to the ensuing outcomes. Strategic decisions considering crucial and irreversible results ...

A novel work was performed for fabrication and modification of composite nanofiltration (NF) membrane by polymerization reaction between polyethyleneimine (PEI) and triphthaloyldechloride (TPC). the main purpose of this ...

Third party service providers are locating logistic hub for operating their tasks. Finding a proper location helps them to have better performance in competitive environment. Multiple characteristics of proper location ...

In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and ...
