Cogent EngineeringThe strengthening of masonry infill wall panels (MIWPs) in reinforced concrete (RC) frame structures is of prime importance due to their failure in the in-plane and out-of-plane direction, as evidenced by past earthquakes.

Frame quasi-uniformities by entourages
, 1995 In this paper we present a theory of quasi-uniformities for frames in terms of entourage that is, special elements of the binary coproduct of the frame by itself, and we prove that this theory is equivalent to J. L.

Flexible Sensors for Robotics Tactile Perception: A Review
Advanced Robotics Research, EarlyView.Flexible tactile sensing for robotics is reviewed through four interconnected dimensions. Physical mechanisms include piezoresistive, capacitive, piezoelectric, triboelectric, iontronic, and optical sensing. Structural design includes bioinspired, defect‐based, and MEMS‐based tactile systems.

Magnetically Actuated Microrobot for Drug Delivery: Current Progress and Challenges
Advanced Robotics Research, EarlyView.Magnetically actuated microrobots are reshaping targeted drug delivery through wireless propulsion, programmable materials, and localized therapeutic release. This review examines how fabrication, body material selection, structural architecture, loading mechanisms, and imaging‐guided control converge to enable microrobotic therapies while identifying ...

WKB Approximation in Noncommutative Gravity
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We consider the quasi-commutative approximation to a noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and geometry is used to study the properties of the high-frequency ...

The semicontinuous frame quasi-uniformity, revisited
, 2009 In this note we present a new treatment of the pointfree version of the semicontinuous quasi-uniformity based on the new tool of the ring of arbitrary (not necessarily continuous) real-valued functions made available recently by J.

Curves of Constant Ratio with Quasi frame in E^3
Türk Doğa ve Fen DergisiIn the present study we handle a regular unit speed curve by means of the position vector given by the vectorial equation γ (s)=m0 t(s)+m1 nq (s)+m2 bq (s) where bq (s), nq (s) and t(s) are quasi frame vectors. Firstly, we analysis these curves and investigate to being constant ratio curve.

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...
