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.

In this paper, numerical simulation of FRP composite cylinder tubes progressive crushing processes is conducted using LS-Dyna. Details on the numerical modeling strategy are given and discussed. It is found that triggers introduced in the numerical simulation can effectively model the bevel trigger at the end of the tubular specimens. It is also found that two-layer finite element model based o...

The mapping of squatter settlements has been a difficult task for geographers (Manoj, 2008). This is due to the dynamic nature of the settlement and the organic growth that these types of settlements take on (Brian, and Ranvinder, 1995). It has proven extremely difficult to accurately map individual households in these settlements and even boundary discernment can be difficult. These issues of ...

Technological advances in the field of 3D data acquisition, modeling and processing enable new possibilities for archaeological documentation, exploration and analysis of individual artifacts, entire excavation sites or reconstructions of past settlements and landscapes. The dissemination of this information together with suitable tools through virtual research platforms requires new methods of...

The improvement of living conditions in informal settlements (IS) is one of the most complex and pressing challenges facing developing countries. In this paper we report on progress towards the automated generation of geospatial databases of informal settlements from large scale, low cost, digital still-video imagery. We focus on shack extraction as the predominant data requirement. In contrast...

in this paper, a modeling tool for risk assessment analysis of the movement of hydrocarbon contaminants in the vadose zone and mass flux of contamination release into the groundwater table was developed. also, advection-diffusion-reaction equations in combination with a three-phase equilibrium state between trapped air, soil humidity, and solid particles of unsaturated soil matrix were numerica...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...

This article demonstrates that in recent years, patent settlements between branded and generic manufacturers involving "reverse payments" from branded manufacturers to generic manufacturers have received close antitrust scrutiny, driven by concerns that such settlements harm consumers by delaying the entry of lower-priced generic drugs. The authors note that such settlements will be a focus of ...
