Lasso regression tends to assign zero weights to most irrelevant or redundant features, and hence is a promising technique for feature selection. Its limitation, however, is that it only offers solutions to linear models. Kernel machines with feature scaling techniques have been studied for feature selection with non-linear models. However, such approaches require to solve hard non-convex optim...

Various methods have been applied to evaluate the effect of erosion and abrasion. So, the aim of this study was to check the applicability of stylus profilometry (SP), surface hardness (SH) and focus-variation 3D microscopy (FVM) to the analysis of human enamel and dentin subjected to erosion/abrasion. The samples were randomly allocated into four groups (n = 10): G1-enamel/erosion, G2-enamel/e...

With the increased use of “Virtual Machines” (VMs) as vehicles that isolate applications running on the same host, it is necessary to devise techniques that enable multiple VMs to share underlying resources both fairly and efficiently. To that end, one common approach is to deploy complex resource management techniques in the hosting infrastructure. Alternately, in this paper, we advocate the u...

Functional volumes modeling (FVM) is a statistical construct for metanalytic modeling of the locations of brain functional areas as spatial probability distributions. FV models have a variety of applications, in particular, to serve as spatially explicit predictions of the Talairach-space locations of functional activations, thereby allowing voxel-based analyses to be hypothesis testing rather ...

Additional to a behavior switching between solid-like and liquid-like, dense granular flows also present propagating grain size-dependent effects called non-local effects. Such behaviors cannot be efficiently modeled by standard rheologies such as µ( I )-rheology but have dealt with advanced models. Unfortunately, these models are still new used easily nor for various configurations. We propose...

To compute accurately radiative transfer in anisotropicallyscattering media, conservation of both scattered energy and angle after discretization is required. Alteration of asymmetry factor (i.e., average cosine of scattering angles) due to angular discretization leads to a third type of numerical error, named as angular false scattering. The error that was known as “false scattering” is actual...

Technology computer-aided design (TCAD) semiconductor device simulators solve partial differential equations (PDE) using the finite volume method (FVM), or related methods. While this approach has been in use over several decades, its methods continue to be extended, and are still applicable for investigating novel devices. In article, we present an element edge based (EEB) FVM discretization s...

This paper begins with presenting a mathematical model for contaminant transport in the fractured vuggy porous media of a species of contaminant PCP . Two phases are numerically simulated for a process of contaminant and clean water infiltrated in the fractured vuggy porous media by coupling mixed finite element MFE method and finite volume method FVM , both of which are locally conservative, t...

In recent years, forest fires and maritime accidents have occurred frequently, which had a bad impact on human production life. Thus, the development of seaplanes is an increasingly urgent demand. It important to study taxiing process for seaplanes, strong nonlinear fluid-structure interaction problem. this paper, Smoothed Particle Hydrodynamics (SPH) method based Lagrangian framework utilized ...
