Repeatability and Parasitic Out‐of‐Plane Motion in Controlled Rocking Structures With Cylindrical Columns: Results From Triaxial Shake Table Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

Nondestructive testing of the space shuttle external tank foam insulation using near field and focused millimeter wave techniques

, 2005
The space shuttle Columbia's catastrophic failure has been attributed to a piece of external tank spray on foam insulation striking the left wing of the orbiter, causing significant damage to some of the reinforced carbon/carbon leading edge wing panels.

Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

Sufficient Gas and Solvated Ion Transport Assisted Rapid NH3 Detection at Room Temperature Through Bionic Olfactory Fibres

Exploration, EarlyView.
Bionic olfactory fibres with nanoconfined ionic liquids were developed to mimic human olfactory cilia. Benefiting from sufficient gas transport pathways provided by inter‐fibre interconnected pores and rapid transport of solvated ions in the confined nano spacing, bionic olfactory fibres show excellent sensing performance to NH3 and demonstrate the ...
