This paper focuses on cover song identification among datasets potentially containing millions of songs. A compact representation of music contents plays an important role in large-scale analysis and retrieval. The proposed approach is based on high-level summarization of musical songs using chord profiles. Search is performed in two steps. In the first step, the Locality Sensitive Hashing (LHS...

This paper presents a novel process of extracting lead oxide nanoparticles from cathode-ray tube (CRT) funnel glass using self-propagating high-temperature synthesis (SHS) method. The impacts of added amount of funnel glass on the extraction ratio of lead, the lead extraction velocity and the micromorphology, as well as particle size of extracted nanoparticles were investigated. We found that s...

The methodology of calculating parameters the primary and secondary non-metallic inclusion formation in thermite alloys is offered. regularities growth time form corundum depending on its size, mass quantity are analysed. It shown that alloy obtained by self-propagating high-temperature synthesis, average size inclusions, surrounding heterogeneous inclusions chromium carbide, 15.4 ?m. during pr...

The paper presents the results of a detailed study process and products combustion during self-propagating high-temperature synthesis (SHS) ZnO zinc oxide powder from mixtures such common reagents as oxidizer nitrate reducing agent (fuel) glycine, well application synthesized highly dispersed submicron nanosized for phenol photocatalytic decomposition under action ultraviolet irradiation. An aq...

In this study, the powders of Ni and Ti with 50.5 at.% Ni for 12 h were blended and cold pressed at the different pressures (50, 75 and100 MPa).The porous product obtained after Ni-Ti compacts were synthesized by SHS (self-propagating hightemperature synthesis) in the different preheating temperatures (200, 250 and 300oC) and heating rates (30, 60 and 90oC/min). The effects of the pressure, pre...

The paper studies the thermophysical properties of a Cu-Ti-C-B composite produced by self-propagating high-temperature synthesis (SHS) an initial mixture copper, titanium, boron carbide (B4C), and carbon powders. matrix is supersaturated solid solution titanium in copper lattice with Cu4Ti nanosized particles homogeneously precipitated under cooling. microhardness 450 HV 0.1. Particles (TiC) di...

Fabrication of FeSi-Al2O3 composites with a molar ratio FeSi/Al2O3 ranging from 1.2 to 4.5 was conducted by the self-propagating high-temperature synthesis (SHS) method. The reaction involved metallothermic reduction Fe2O3 and SiO2 Al chemical interaction Fe Si. Two combustion systems were examined: one contained thermite reagents 0.6Fe2O3 + 0.6SiO2 2Al, other had 2Al mix different amounts Si p...

In the present study, nearly fully dense monolithic ZrC samples are produced and broadly characterized from microstructural, mechanical and optical points of view. Specifically, 98% dense products are obtained by Spark Plasma Sintering (SPS) after 20 min dwell time at 1850 °C starting from powders preliminarily prepared by Self-propagating High-temperature Synthesis (SHS) followed by 20 min bal...

Hydrophilic graphene sheets were synthesized from a mixture of magnesium and gallic acid (GA) modified graphene oxide (GO) in a self-propagating high-temperature synthesis (SHS) process, and hydrophilic graphene sheets displayed the higher C/O ratio (16.36), outstanding conductivity (~88900 S/m) and excellent water-solubility. GO sheets were connected together by GA, and GA was captured to darn...
