Case studies of circular shaft construction in London

Geotechnical Engineering, 2018
At present, there are few well-documented case studies of circular shaft construction, making it difficult for designers to estimate reliable ground movements arising from such construction.

Active Piezoelectric Control of Three-Dimensional Vibration in a Flexible Circular Shaft via a Fuzzy Adaptive PID Algorithm

Actuators
Flexible circular shafts are critical components for power transmission in engineering systems. However, they are susceptible to complex three-dimensional coupled vibrations under multidirectional excitations, which can compromise operational stability ...

Time-Reversal SAR Imaging for Nondestructive Testing of Circular and Cylindrical Multilayered Dielectric Structures

IEEE Transactions on Instrumentation and Measurement, 2020
In this paper, a synthetic aperture radar (SAR) approach, for imaging internal structures of generally lossy layered dielectric cylindrical objects, is presented. This method which properly accounts for different transmission and refraction paths at each

Semi‐Analytical Solution of Time‐Harmonic Soil–Pile Interaction Using Love Numbers in Transversely Isotropic and Layered Half‐Spaces

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4691-4705, 10 August 2026.
ABSTRACT An efficient semi‐analytical approach based on the Fourier–Bessel series (FBS) system of vector functions and the stiffness matrix method is proposed to study the dynamic response of axially loaded piles embedded in transversely isotropic (TI) layered soil.

Bound by blood and bloodshed: Sibling ties and participation in genocidal violence

Criminology, Volume 64, Issue 3, Page 619-654, August 2026.
Abstract Focusing on the 1994 genocide in Rwanda, we examine how sibling relationships—one of the most salient familial bonds—influence individual engagement in violence during mass atrocity. Drawing on an adaptation of differential association and social learning theories for contexts of mass atrocity, we analyze a novel dataset linking over 300,000 ...

Theoretical and experimental modal analysis of circular cross-section shaft

IOP Conference Series: Materials Science and Engineering, 2020
Experimental Modal Analysis (EMA) is very helpful in engineering design and manufacturing of machine components. In this paper, modal parameters which are natural frequencies, mode shapes and damping ratios are extracted for free-free boundary conditions

Cultura caballista

American Ethnologist, Volume 53, Issue 3, Page 296-309, August 2026.
Abstract The world of Colombian gaited horses, or cultura caballista (horse‐riding culture), is often linked with uribismo, the right‐wing identity associated with former president Álvaro Uribe Vélez. Ethnographic fieldwork in conflict‐torn Antioquia reveals how horse‐human practices of training, breeding, and competition cultivate orientations toward ...

A Closed-Form Solution of Prestressed Annular Membrane Internally-Connected with Rigid Circular Plate and Transversely-Loaded by Central Shaft

Mathematics, 2020
In this paper, we analytically dealt with the usually so-called prestressed annular membrane problem, that is, the problem of axisymmetric deformation of the annular membrane with an initial in-plane tensile stress, in which the prestressed annular ...
