Scaling effect in cone penetration testing in sand
… That is, it is assumed that there are no scale effects in cones of different sizes. While this may be true, to date, little direct evidence has been produced to support this view, and the issue is an important one from two points of view: 1. The present data analysis technology is based on that …

Physical modeling of local scour around complex bridge piers
… river and bridge cross sections to consider the effect of river bathymetry and bridge geometry. Three different sizes of sediment and several geometric scales of the bridge pier models were used in this study to investigate the scaling effect of relative sediment size, which is defined as the …

Scaling and process effect on electromigration reliability for Cu/low k interconnects
… RC delay problem arising from aggressive line scaling, by replacing aluminum (Al) by copper (Cu) and oxide dielectric by low-k dielectric. Electromigration (EM) turned out to be a serious reliability problem for Cu interconnects due to the implementation of mechanically weaker low-k …

Homogenization and elastic-plastic transitions in random and FGM microstructures
… uses homogenization as a tool to estimate the effective properties of heterogeneous materials with varying microstructures. Separation of scales (Micro (d), Meso(δ), Macro (L)), in these microstructures leads to the problem of determination of the Representative Volume Element (RVE) that …

Numerical study on scaling effects and decoupled network-based simulation of gaseous explosion
<p>"This research seeks to improve the prediction efficiency of gaseous explosions realized by numerical simulations in a full-scale underground network using a decoupled method. To provide quick predictions of overpressure distribution of methane explosions in underground airway networks, a …

Substrate-dependent high-field transport and self-heating in graphene transistors
… and thermal transport in graphene field-effect transistors (GFETs). We developed a simple yet practical electro-thermal model along with extensive calibration with experimental data. Special emphasis is given to the study of high-field transport and investigation of temperature-induced …
