This paper describes the results of numerical analysis effects installing a driven pile. The geometry problem has been simplified by assumption plane strain conditions in addition to axial symmetry. Pile installation modelled as undrained expansion cylindrical cavity. excess pore pressures generated this process have subsequently assumed dissipate means outward radial flow water. consolidation soil studied using work-hardening elasto–plastic model which unique feature allowing strength...
Closed form solutions are presented for the expansion of cylindrical and spherical cavities in an ideal, cohesive frictional soil. An explicit solution pressure-expansion relationship can be obtained infinitesimal (small strain) deformations. For finite deformations it is necessary to adopt a numerical approach obtain complete found that cavity pressure approaches limiting value infinite deformation. It is, perhaps surprisingly, possible determine precise this analytically. suggested small...
Abstract Aim Comparative analyses of fire regimes at large geographical scales can potentially identify ecological and climatic controls fire. Here we describe A ustralia's broad regimes, explore interrelationships trade‐offs between regime components. We postulate that patterns will be governed by moisture, productivity, frequency intensity. Location Australia. Methods reclassified a vegetation map ustralia, defining classes based on typical fuel types. Classes were intersected with climate...
Given the continuing advances in gait biometrics, it appears prudent to investigate translation of these techniques for forensic use. We address question as confidence that might be given between any two such measurements. use locations ankle, knee, and hip derive a measure match walking subjects image sequences. The Instantaneous Posture Match algorithm, using Harr templates, kinematics, anthropomorphic knowledge is used determine their location. This demonstrated real CCTV recorded at...
A theoretical study of the behaviour structured soil is presented. new model, referred to as Structured Cam Clay formulated by introducing influence structure into Modified model. The proposed model hierarchical, i.e., it identical if a has no or its removed loading. Three parameters describing effects are introduced, and results parametric also been used predict soils in both compression shearing tests. By making comparisons predictions with experimental data conducting demonstrated that...
This paper presents the results of three-dimensional finite-element analyses circular foundations on surface homogeneous, purely cohesive soil. The were assumed to adhere fully soil, and compressive, tensile shear stresses may develop at interface between footing predicted ultimate response combined vertical, moment horizontal loading was compared with other available theoretical predictions. A failure locus is presented for these foundations, based numerical An equation that approximates...
The stress–strain behaviour of sands is highly nonlinear, even at stresses well below the peak strength sand. hyperbolic model a reasonable conceptual for representing sand, but some empirical curve fitting required to obtain more realistic calculation purposes. This can readily be performed reconstituted samples sand using laboratory tests. Recent evidence shows that stiffness natural often much greater than same when density and stress state in laboratory, it therefore necessary use situ...
The deformation characteristics of soil subjected to vacuum pressure are discussed and an approximate method is proposed for calculating settlement lateral displacement the ground induced by consolidation. Laboratory oedometer test results indicate that if alone larger than stress required maintain at-rest (no horizontal strain) condition, there will be inward induce generally less a surcharge load same magnitude. In case field consolidation, confining acting on element can regarded as...

Abstract The disturbance of a clay mass, due to either the installation driven pile or expansion pressuremeter membrane, is often modelled as cylindrical cavity expansion. In addition, it usual (and convenient) assume that occurs under conditions plane strain. For this problem method analysis presented which considers soil be saturated two‐phase material with pore fluid flows according Darcy's Law. Non‐linearity in behaviour permitted long effective stress–strain law can written an...
We present data on soil organic carbon (SOC) inventory for 7050 cores collected from a wide range of environmental conditions throughout Australia. The set is stratified over the spatial distribution trees and grass to account variability SOC with vegetation distribution. model controls using an index water availability mean annual temperature represent climatic control rate C input into pool decomposition SOC, in addition fraction particles <63 μm diameter as measure textural...
This paper presents a simple approach to quantify the effect of initial soil density on soil-water characteristic curve (SWCC) unsaturated soils. is based an incremental relationship between degree saturation and void ratio, which satisfies intrinsic constraints for three-phase porous materials. The can be incorporated into existing SWCC equations model water retention behaviour deformable Only one additional parameter introduced, conveniently calibrated by way conventional tests. SWCCs same...
Multi-tenant datacenters are successful because tenants can seamlessly port their applications and services to the cloud. Virtual Machine (VM) technology plays an integral role in this success by enabling a diverse set of software be run on unified underlying framework. This flexibility, however, comes at cost dealing with out-dated, inefficient, or misconfigured TCP stacks implemented VMs. paper investigates if administrators take control VM's congestion algorithm without making changes VM...
The acute toxicities of 19 chemicals were assessed using G. mellonella larvae. results obtained compared against LD50 values derived from in vitro cytotoxicity tests and vivo oral values. In general, cell culture systems overestimated the toxicity chemicals, especially low chemicals. contrast, testing larvae was found to be a reliable predictor for For 9 tested which assigned Globally Harmonised System (GHS) category 5, measured consistent with their GHS categorisation but 3T3 or NHK cells...
This paper describes a study of the virgin compression behaviour both naturally and artificially structured soils under one-dimensional or isotropic compression. It is proposed that during compression, additional voids ratio sustained by soil structure inversely proportional to current mean effective stress. The formula has been verified for 20 different soils, it seen proposal well all these soils. Finally, general discussion on its features presented, equation extended describe along...
