Audio Classification from Time-Frequency Texture

, 2008
Time-frequency representations of audio signals often resemble texture images. This paper derives a simple audio classification algorithm based on treating sound spectrograms as texture images.

Electroactive Microbes Short-Circuit the Passive Film to Corrode Stainless Steel

Research
Electroactive microbes are uniquely capable of aggressively corroding metals like stainless steel that were once thought immune to microbial attack. This activity has been attributed to microbial destruction of the protective chromium oxide passive film ...

Wear Resistance of Iron Matrix Composites Reinforced by Mixed-type Particles

Cailiao gongcheng, 2017
Ceramic particles reinforced iron matrix composites were prepared by the dynamic temperature resistant hot press technology. The wear resistance of the iron matrix composites reinforced by monolithic particles (SiC,TiC,TiN) and hybrid particles mixture ...

Scale Selective Extended Local Binary Pattern for Texture Classification

, 2018
In this paper, we propose a new texture descriptor, scale selective extended local binary pattern (SSELBP), to characterize texture images with scale variations.

PLGA and Mg(OH)₂ Composite Coatings on Zinc Alloy for Improving Degradation Resistance and Cell Compatibility

Metals
To address the issue of burst release of Zn2+ ions in the early degradation stage of degradable zinc alloys and enhance their cellular activity, a composite coating consisting of PLGA and Mg(OH)2 was prepared on the surface of Zn alloys.

Texture and Cofactor Zeros of the Neutrino Mass Matrix

, 2014
We study Majorana neutrino mass matrices that have two texture zeros, or two cofactor zeros, or one texture zero and one cofactor zero. The two texture/cofactor zero conditions give four constraints, which in conjunction with the five measured ...
