Analysis of Influence Factors of Negative Skin Friction on PHC Pile in High-Backfill Sites

open access: yesFrontiers in Physics, 2022
It is recognized that NSF on a pile affects the structural and geotechnical design. The formation of NSF on a pre-stressed high-strength concrete (PHC) pile under a control building in a Vietnamese project was investigated using a verified numerical ...

Effect of Elastically Restrained Edges on Free Transverse Vibration of Functionally Graded Porous Rectangular Plate [PDF]

open access: yesMechanics of Advanced Composite Structures, 2022
In this paper, the author studied free transverse vibration of a thin isotropic simply-supported functionally graded (FG) rectangular plate with porosity effect based on classical plate theory. The plate is considered to be elastically restrained against

Influence of fire position on smoke movement in an inner corridor building with multiple openings [PDF]

open access: yesE3S Web of Conferences, 2019
The influence of fire position on the neutral plane height was analyzed in order to analyze the smoke movement. One inner corridor building multiple openings was constructed by computational fluid dynamics (CFD) software and the airflow velocity and the ...

The distribution of neutral hydrogen in the colour–magnitude plane of galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2020
ABSTRACT We present the conditional H i (neutral hydrogen) mass function (HIMF) conditioned on observed optical properties, Mr (r-band absolute magnitude), and Cur (u − r colour), for a sample of 7709 galaxies from Arecibo Legacy Fast ALFA (40 per cent data release – α.40) which overlaps with a common volume in SDSS DR7.

Nonlinear neutral modes in zero-mass-flux Plane poiseuille-couette flow

open access: yesQuarterly Journal of Mechanics and Applied Mathematics, 2023
SummaryPlane Poiseuille–Couette flow with zero mean advection velocity, a flow well known to be linearly stable, is analysed at asymptotically large Reynolds number R. A nonlinear neutral mode structure is uncovered which is self-sustained due to the interaction of the viscous wall layers with a predominantly inviscid nonlinear internal critical layer.

Accuracy of CT Derived Patient Specific Instrumentation for Total Ankle Arthroplasty: The Impact of the Severity of Preoperative Varus Ankle Deformity

open access: yesFoot & Ankle Orthopaedics, 2022
Category: Ankle; Ankle Arthritis Introduction/Purpose: Significant preoperative varus tibiotalar deformity was once believed to be a contraindication to performing total ankle arthroplasty (TAA).

Enhancing the shape memory effect of Cu–Al–Ni alloys via partial reinforcement by alumina through selective laser melting

open access: yesJournal of Materials Research and Technology, 2021
Cu–Al–Ni shape memory alloys (SMAs) have high thermal stability and various potential applications. The most significant factors limiting their application are their relatively low elastic strain and poor shape memory effect known as recoverable strain ...

Impact of Tibial Component Coronal Alignment on Knee Joint Biomechanics Following Fixed‐bearing Unicompartmental Knee Arthroplasty: A Finite Element Analysis

open access: yesOrthopaedic Surgery, 2021
Objective Unicompartmental knee arthroplasty (UKA) has indicated a higher rate of revision than total knee arthroplasty (TKA). The success of UKA depends on UKA component alignment, fixation, and soft tissue integrity.

Axisymmetric bending oscillations of stellar disks [PDF]

open access: yes, 1996
Self-gravitating stellar disks with random motion support both exponentially growing and, in some cases, purely oscillatory axisymmetric bending modes, unlike their cold disk counterparts.
