This paper studies a novel audio segmentation-by-classification approach based on Factor Analysis (FA) with a channel compensation matrix for each class and scoring the fixed-length segments as the log-likelihood ratio between class/no-class. The system described here is designed to segment and classify the audio files coming from broadcast programs into five different classes: speech (SP), spe...

An integrated approach for estimation and reduction of measurement variation (and its components) through a single parameter design experiment is developed. Systems with a linear signal-response relationship are considered. The noise factors are classified into a few distinct categories based on their impact on the measurement system. A random coefficients model that accounts for the effect of ...

The π/π ratio is examined as a function of isospin asymmetry and beam energy for central collisions induced by neutron-rich nuclei within an isospindependent hadronic transport model. The π/π ratio is found to increase with the isospin asymmetry, but decrease with the beam energy of the reaction. For neutron-rich systems, such as, Sn + Sn and Sn + Sn, the sensitivity of π/π ratio to nuclear sym...

In Sn-I-Sn-I-Pb tunneling structures the energy gap ~Sn of Sn is reduced by quasiparticle injection via single-particle tunneling between the Sn films. ~Sn as function of the quasiparticle density is probed by the Pb contact and found in agreement with the theory of OWen and Scalapino. An instability of the energy gap of Sn is observed at the critical gap reduction ratio predicted by this theor...

Ship noise observation is of great significance to marine environment research and national defense security. Acoustic stealth technology makes a variety ship significantly reduced, which new challenge for monitoring. However, there are few high spatial gain detection methods low-noise Therefore, Signal-to-Noise Ratio (SNR) MEMS listener developed in this paper. The achieves considerable by sup...

Penumbral imaging is a powerful imaging technique for radiations with long mean-free path. Since the reconstruction is based on deconvolution, the technique is sensitive to noise contained in penumbral images. Uniformly redundant penumbral array (URPA) technique can improve the SN ratio of penumbral images. In URPA, the penumbral apertures are arranged in m-sequence. In the reconstruction proce...

In the present study, we propose a continuous assay for the screening of sn-2 lipases by using triacylglycerols (TAGs) from Aleurites fordii seed (tung oil) and a synthetic TAG containing the α-eleostearic acid at the sn-2 position and the oleic acid (OA) at the sn-1 and sn-3 positions [1,3-O-dioleoyl-2-O-α-eleostearoyl-sn-glycerol (sn-OEO)]. Each TAG was coated into a microplate well, and the ...

In the title compound, [Sn(C6H5)3(C2H3OS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry. A short Sn⋯O contact [2.988 (4) Å] is also present. The phenyl rings are each disordered over two sets of sites with an occupancy ratio of 0.550 (8):0.450 (8). The crystal studied was found to be a racemic twin with a twin component ratio of 0.57 (18):0.43 (18).

Abstract To improve the tribological performance of CSS-42L bearing steel, smooth surfaces (SSs), groove-textured (GSs), GSs with Sn-Ag-Cu (GSs-SAC), and Sn-Ag-Cu-Ti 3 C 2 (GSs-SACT) were prepared on CSS-42L. In addition, experimental studies conducted properties. The obtained results indicated that GSs-SACT exhibited best anti-friction noise reduction performances. These remarkable performance...
