When analyzing a single line-to-ground fault from phase A to ground at a three-phase bus, it is important to consider the fault impedance. This impedance is zero for a bolted fault, equal to the arc impedance for an arcing fault, and represents the total fault impedance for a transmission-line insulator flashover. To derive sequence and phase currents, fault conditions are translated from the phase domain to the sequence domain. For line-to-line faults occurring between phases B and C, the...

Scalable engineered blood vessels would improve clinical applicability. Using easily sizable 3D-printed guides, rings of vascular smooth muscle were created and stacked into a tubular form, forming a vascular graft. Grafts can be sized to meet the range of human coronary artery dimensions by simply changing the 3D-printed guide size.

In this paper, an adaptive filter based on a normalized least mean square (NLMS) algorithm and a rotational speed estimation method are introduced to detect the electrical and hydraulic faults of the electro-hydrostatic actuator (EHA). The efficacy and feasibility of the aforementioned methods are verified through simulations and experiments.
FAQs
Intrinsic and extrinsic stacking faults represent different interruptions of the expected layer sequence in a close-packed crystal. Their distinct local arrangements produce different bonding environments and energies. This distinction matters because the two configurations can influence crystal stability and phase behavior differently, allowing researchers to connect a specific defect structure with changes in the material’s properties.
A partial dislocation can shift part of one atomic layer relative to the surrounding layers, changing the sequence expected in the close-packed structure. The shifted region leaves a planar boundary with altered local bonding. This mechanism connects stacking faults with plastic deformation, because dislocation motion changes the crystal arrangement rather than preserving perfect layer registry.
The local bonding and energy associated with a stacking fault determine how favorable the defect is within the crystal. Because intrinsic and extrinsic configurations have distinct energies, they can affect crystal stability and the tendency toward structural change. These energetic differences help explain why defect structure is important when interpreting phase transformations in crystalline solids.
Analyzing stacking faults can reveal how atomic-scale disorder relates to larger structural behavior. In particular, these defects can contribute to characteristic changes in diffraction patterns, which helps distinguish variations in crystal structure. Such analysis provides a way to connect the local layer sequence with crystal stability, phase transformations, and deformation-related behavior.
Stacking faults can modify the local atomic arrangement and bonding within a crystal, potentially influencing how the solid behaves in catalytic or electronic contexts. Their presence therefore provides a structural variable for interpreting differences in material performance. In chemistry and materials research, identifying these defects helps relate measured functional behavior to atomic-scale crystal organization.
These defects serve as a link between changes in crystal structure and mechanical response. A disrupted layer sequence can reflect or accompany partial-dislocation activity, while the defect’s local energy can affect structural stability during phase transformation. Studying both aspects helps researchers interpret how atomic rearrangements produce observable changes in deformation and phase behavior.
