Toward More Autonomous Soft Robots: Development and Characterization of a 3D‐Printed Pneumatic Contact Sensor for a Six‐Legged Soft Robotic Walker

Advanced Intelligent Systems, EarlyView.
This article introduces a fully 3D‐printed, electronics‐free sensory system for a six‐legged soft robot, enabling adaptive responses such as obstacle detection and directional changes using pneumatic logic gates. The design demonstrates efficient, robust operation through rapid sensor feedback and autonomous functionality, highlighting new ...

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Seismic behaviour of reinforced concrete frame with infill panels

MATEC Web of Conferences, 2018
Infill panels are usually used in structures; therefore, it is very important to study their behaviour and their influence on bare frames. Several models had been proposed to understand the effect of the infill panels on structure.

Validation of a simplified micromodel for analysis of infilled RC frames exposed to cyclic lateral loads [PDF]

, 2016
An RC frame structure with masonry infill walls (‘‘framed-masonry’’) exposed to lateral loads acts as a composite structure. Numerical simulation of framed-masonry is difficult and generally unreliable due to many difficulties and uncertainties in its ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Modeling of masonry infilled RC frames with different aspect ratios using plastic hinge and equivalent strut

Journal of Engineering and Applied Science
The existence of diverse modeling approaches for masonry-infilled frames causes uncertainty among practicing engineers when seeking a definitive model for their design practice.

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

Deep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Effect of infill wall on the ductility and behavior of high strength reinforced concrete frames

HBRC Journal, 2014
This paper presents an experimental study for the behavior and ductility of H.S.R.C frames with infill wall under the effect of cyclic load. The experimental program was conducted on four specimens (frames).

Seismic Retrofitting of RC Frames with RC Infilling [PDF]

, 2012
The effectiveness of seismic retrofitting of multi-storey multi-bay RC-frame buildings, by converting selected bays into new walls through infilling with RC, was studied experimentally at the ELSA facility at JRC, Ispra, and the results are reported here.
