In the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. Effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

background: as various implant geometries present different biomechanical behaviors, the purpose of this work was to study stress distribution around tapered and cylindrical threaded implant geometries using three-dimensional finite element stress analysis.     methods: seven implant models were constructed using the cad system. after digitized models of mandibular section, the crowns were crea...

Resilient modulus of pavement materials is a key property required for the pavement thickness design. This paper describes the results of an experimental study on the effects of temperature and loading frequency on the resilient modulus of a SBS polymer modified asphalt concrete under dry and saturated conditions. Dynamic creep tests were conducted on dry and saturated specimens of the mixture ...

An adaptive mesh refmement (AMR) version of CTH is currently under development. This project is being conducted jointly by researchers at the University of Texas and at Sandia National Laboratories. The AMR version of CTH represents a significant milestone in the ten-year development of this legacy code. CTH is a multi-material wave propagation code used by many analysts in the DoD user communi...

Reclaimed asphalt pavement (RAP) is one of the waste materials that highway agencies promote to use in new construction or rehabilitation of highways pavement. Since the use of RAP can affect the resilient modulus and other structural properties of flexible pavement layers, this paper aims to employ two different artificial neural network (ANN) models for modeling and evaluating the effects of ...

Now a day’s multiplication and modulus takes crucial role so we are combining multiplication and modulus. A Novel multi-modulus multiplier with different widths of modulus operations. In this paper we have radix4 multi-modulus multiplier with 4bit, 32bit, 64bit and radix8 multi-modulus multiplier with 4bit, 32bit, 64bit.radix4 and radix8 multi-modulus multiplier using Residue multiplication is ...

background: common carotid arterial stiffness can be assessed during carotid arterial ultrasonography, but its association with brachial stiffness, a well-defined cardiovascular risk factor, has not been clarified. the aim of this study was to examine the relationship between common carotid artery and brachial artery stiffness. methods: the static pressure-strain elastic modulus of the common c...

In the 1970s, O'Keefe and Dostrovsky discovered that certain neurons, called place cells, in an animal's brain are tied to its location within arena. A combinatorial neural code is a collection of $0/1$-vectors which encode patterns co-firing activity among cells. Gross, Obatake, Youngs have recently used techniques from toric algebra study when $0$- $1$-, or $2$-inductively pierced: property a...

a new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. the total elastic modulus of nano-composite is evaluated.  numerical results are in good agreement with the previous proposed theoretical modeling. higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.
