Penetration of fastener projectiles into construction materials [PDF]

open access: yes, 1988
The normal impact, penetration of both projectile and fastener into soils, rocks, and concrete at low velocities has been investigated using theoretical, experimental, and numerical approaches under axisymmetric conditions.

A Review on Sensor Technologies, Control Approaches, and Emerging Challenges in Soft Robotics

open access: yesAdvanced Robotics Research, EarlyView.
This review provides an introspective of sensors and controllers in soft robotics. Initially describing the current sensing methods, then moving on to the control methods utilized, and finally ending with challenges and future directions in soft robotics focusing on the material innovations, sensor fusion, and embedded intelligence for sensors and ...

Evaluation of bed shear stress under turbid flows through measures of flow deceleration

open access: yes, 2006
In previous work it has been observed that the direct application of the law-of-the-wall in flows of high concentrations of cohesive sediments, results in overestimation of the bed shear stress.

The measurement of the in situ compressional wave properties of marine sediments [PDF]

open access: yes, 2007
Geoacoustic inversion requires a generic knowledge of the frequency-dependence of compressional wave properties in marine sediments, the nature of which is still under debate. The use of in situ probes to measure sediment acoustic properties introduces a

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Constraining uplift and denudation of West African continental margin by inversion of stacking velocity data.

open access: yes
An inverse model has been developed to determine the magnitude of denudation at seabed and subsurface unconformities by using root-mean-square (RMS) stacking velocity data derived from processing a set of seismic reflection profiles.

The anelastic structure and deep geology of the Derbyshire Dome from high frequency Rayleigh waves. [PDF]

open access: yes, 1984
This work is an investigation of the anelastic structure of the Derbyshire Dome and adjacent areas from the analysis of high frequency, 0.6 - 4.2 Hz, fundamental mode Rayleigh waves observed from quarry blasts within the study area.

Printable Conductive Hydrogels for Electrochemical Biosensing and Soft Bioelectronic Interfaces

open access: yesAdvanced Science, EarlyView.
Flexible, conductive hydrogels that integrate printability, mechanical tunability, biocompatibility, and electronic performance remain challenging to achieve. Here, we develop 3D‐printable poly(ethylene glycol)–poly(pyrrole)‐ hydrogels with tissue‐like mechanics, high cytocompatibility, and robust electrochemical function.

Dispersion of Love Waves in a Composite Layer Resting on Monoclinic Half-Space

open access: yesJournal of Applied Mathematics, 2011
Dispersion of Love waves is studied in a fibre-reinforced layer resting on monoclinic half-space. The wave velocity equation has been obtained for a fiber-reinforced layer resting on monoclinic half space.
