Determining characteristics of the inlet collector with interceptor for gas turbine engine test rig

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
To determine the characteristics of an inlet channel with a segmented interceptor used to generate inlet non-uniformity in a gas turbine engine during bench testing, a numerical quasi-steady-state model of non-uniform flow is proposed.

Transition from rectification to resistive-switching in Ti/MgF2/Pt memory

open access: yesAIP Advances, 2019
Magnesium fluoride is a promising candidate for resistive-switching random access memory (RRAM) with biodegradable property. However, the underlying resistive-switching (RS) mechanism and conduction mechanism in MgF2 material is still not fully studied ...

Planar Quasi-Isotropic Magnetic Dipole Antenna Using Fractional-Order Circular Sector Cavity Resonant Mode

open access: yesIEEE Access, 2017
The radiation behavior of the fractional-order, resonant mode within a circular sector cavity radiator is revealed at first, and then, it is employed to design a novel, planar quasi-isotropic magnetic dipole antenna.

Load Distributing Metamaterials Via Discrete Optimization

open access: yesAdvanced Functional Materials, EarlyView.
Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Reservoir‐Driven Neuromorphic Computing Based on Composite Rare‐Earth/Transition Metal Oxide Memristor

open access: yesAdvanced Functional Materials, EarlyView.
A defect‐engineered Ag/Gd2O3:Nb2O5/Pt rare earth composite oxide memristor enables stable multilevel reservoir states through pulse driven conductance modulation. Experimentally measured device responses are incorporated into a device aware reservoir computing framework for CIFAR‐100 image classification, highlighting the potential of rare earth ...

Topological Spaces with a Unique Compatible Quasi-Uniformity

open access: yes, 1971
In [ 2 ] P. Fletcher proved that a finite topological space has a unique compatible quasi-uniformity; C. Barnhill and P. Fletcher showed in [1] that a topological space (X, ), with finite, has a unique compatible quasiuniformity.

Hyperconvexity and endpoints in T₀-quasi-metric spaces [PDF]

open access: yes, 2013
Over the last decades much progress has been made in the investigation of hyperconvexity in metric spaces. Recently Kemajou and others have published an article concerning hyperconvexity in T₀-quasi-metric spaces.

Dynamically tunable long-range coupling enabled by bound state in the continuum

open access: yesLight: Science & Applications
Formation and dynamic control of strong coupling among cavities are essential to realize advanced functional photonic and quantum circuits. Especially for cavities at distant distance or arbitrary locations.

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

open access: yesAdvanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.

Concerning completeness of the fine quasi-uniformity

open access: yes, 1996
[EN] A quasi-uniform space (X,U) is called strongly complete if every stable filter on (X, U-1) has a cluster point and it is called hypercomplete if every stable filter on (X,U) has a cluster point.
