Advanced Engineering Materials, EarlyView.X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...

Advanced Engineering Materials, EarlyView.Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design
Advanced Engineering Materials, EarlyView.This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

Advanced Engineering Materials, EarlyView.In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.

Determination of the Impedance Matching Domain of Impedance Matching Networks
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2004This paper investigates the impedance boundary of impedance matching networks analytically, graphically representing the resultant impedance matching domains. A set of explicit equations is derived to allow the rapid development of the impedance boundary of such networks.

Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002
In many applications, it is desirable to synthesize an adaptive impedance to match some "real world" system, so that when the target impedance changes, the matching impedance tracks this change and maintains a close match. In this paper we present a scheme for adaptive impedance matching formulated in the Model Reference Adaptive Systems' Control (MRAS)

Impedance Matching in RFID Tags: to Which Impedance to Match?
2006 IEEE Antennas and Propagation Society International Symposium, 2006This paper presents an analysis of impedance matching in passive radio frequency identification (RFID) tags. RFID chip impedance varies with frequency and with the power absorbed by the chip. The variation of this impedance with power can drastically affect the performance of the chip. We show how the impedance variation of the chip front makes the tag

Quasi-Orthogonal Grids with Impedance Matching
SIAM Journal on Scientific Computing, 2000This paper presents a general elliptic grid generation system based on quasi-conformal mapping for arbitrary anisotropic regions. This system can be used to construct quasi-orthogonal smooth grids with an externally specified spacing normal to the boundaries of the domain.
