This study proposes to use a method of nonlinear, nonstationary data processing and analysis, i.e., the Hilbert-Huang transform (HHT), to explore and characterize the signatures of soil nonlinearity and/or liquefaction from earthquake ground recordings. The paper first summarizes symptoms of soil nonlinearity and liquefaction shown in earthquake ground motion recordings. It then reviews the Fou...

The amount of wood residue is used as a measurement of the extent of wood liquefaction. Characterization of the residue from wood liquefaction provides a new approach to understand some fundamental aspects of the liquefaction reaction. Residues were characterized by wet chemical analyses, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand-fines mixtures under cyclic loading. results triaxial tests conducted Hostun sand with varying amounts (0–20%) types (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method, consolidated...

Liquefaction of human semen involves proteolytic degradation of the seminal coagulum and release of motile spermatozoa. Several members of human kallikrein-related peptidases (KLKs) have been implicated in semen liquefaction, functioning through highly regulated proteolytic cascades. Among these, KLK3 (also known as prostate-specific antigen) is the main executor enzyme responsible for processi...

The wood biomass was liquefied by the pressurized hydrothermal method. The wood biomass powder in the different particle size, which was pulverized by a vibration mill, cutter mill and grinder, was used for the liquefaction. The liquefaction material was biomass slurry, which was prepared by mixing the wood biomass powder and water together (1:9). After filling the biomass slurry in a pressure ...

A comprehensive experimental study that quantifies the influence of coupled compression and shear wave loading on liquefaction susceptibility sands is presented. Such typical in situ, leads to complex principal stress rotation, which turn impacts potential for soils even if cyclic intensity remains constant. The nature degree rotation caused by this are significantly influenced initial consolid...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand–fines mixtures under monotonic loading. results triaxial compression tests conducted Hostun sand with varying amount (0–20%) type (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method ...

Third Graders’ Misconceptions about Evaporation and Liquefaction Phenomena A. Badriyaan, Ph.D. Concepts of evaporation and liquefaction are of significance in both daily life and the school curriculum, yet misconceptions about these two phenomena are frequent. To assess the extent of such misconceptions among third graders, a cluster sample of 132 of them from four schools i...

This paper presents prediction of liquefaction potential of soils by neuro-fuzzy models evaluated using Idriss and Boulanger method. In order to address the collective knowledge built up in conventional liquefaction method, an alternative Takagi-Sugeno-Kang reliant neuro-fuzzy model has been developed. Neuro-fuzzy is one of the artificial intelligence approaches that can be classified by machin...
