let a and b be n × m matrices. the matrix b is said to be g-row majorized (respectively g-column majorized) by a, if every row (respectively column) of b, is g-majorized by the corresponding row (respectively column) of a. in this paper all kinds of g-majorization are studied on mn,m, and the possible structure of their linear preservers will be found. also all linear operators t : mn,m ---> mn...

Linville Gorge Wilderness (LGW) is a Class I area in the southern Appalachian Mountains, western North Carolina. Over the last 150 years, LGW has been subject to several wildfires, varying in intensity and extent (Newell and Peet 1995). In November 2000, a wildfire burned 4000 ha in the wilderness; the fire ranged in severity across the northern portion of the wilderness from low severity in co...

This work presents a fusion of Log Gabor Wavelet (LGW) and Maximum a Posteriori (MAP) estimator as a speech enhancement tool for acoustical background noise reduction. The probability density function (pdf) of the speech spectral amplitude is approximated by a Generalized Laplacian Distribution (GLD). Compared to earlier estimators the proposed method estimates the underlying statistical model ...

Two-dimensional quantum systems with competing orders can feature a deconfined critical point, yielding continuous phase transition that is incompatible the Landau-Ginzburg-Wilson scenario, predicting instead first-order transition. This caused by LGW order parameter breaking up into new elementary excitations at point. Canonical candidates for criticality are antiferromagnets magnetic orders, ...

Title of dissertation: ASYMMETRIC FLUID CRITICALITY Christopher Elliot Bertrand, Doctor of Philosophy, 2011 Dissertation directed by: Professor Mikhail Anisimov, Institute for Physical Science and Technology & Department of Chemical and Biomolecular Engineering This work investigates features of critical phenomena in fluids. The canonical description of critical phenomena, inspired by the Ising...

Glasswort (Salicornia herbacea L.) is a halophyte plant known to contain high contents of minerals and phytochemicals. The purpose this study was investigate the effect fermented glasswort on gut health in D-galactose (D-gal)-induced aging rats. Forty rats were randomly divided into five groups: control (CON), D-gal alone (CD), plus fructooligosaccharide as positive (FOS, 400 mg/kg), low dose (...

Groundwater plays a crucial role in triggering and reactivating deep-seated landslides. However, classical hydrogeological investigations have limitations their applicability to landslides due anisotropic heterogeneous media. The Huangtupo landslide the Three Gorges Reservoir area has garnered significant attention its high hazard potential. Of particular interest is NO.1 Riverside Sliding Mass...

Real world Speaker Identification (SI) application differs from ideal or laboratory conditions causing perturbations that leads to a mismatch between the training and testing environment and degrade the performance drastically. Many strategies have been adopted to cope with acoustical degradation; wavelet based Bayesian marginal model is one of them. But Bayesian marginal models cannot model th...

Research background: After the recent restart of global economy, at least in Asia, Europe and U.S., one main suffering industries is aviation. As a principal consequence quarantine closing borders, most people cancelled their flights pushing airlines companies to edge abyss therefore it looks interesting understand how far they could go what operating limit are. If moment we have heard news abo...
