A Real-Time Millimeter-Wave Phased Array MIMO Channel Sounder
In this paper, we present a novel real-time MIMO channel sounder for 28 GHz. Until now, the common practice to investigate the directional characteristics of millimeter-wave channels has been using a rotating horn antenna.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Parametric Analysis in the Optimization Design of Composite Cellular Beams
This study aims to present a parametric analysis in the optimization problem for steel-concrete composite cellular beams with steel deck slabs. A comparative analysis was carried out considering two scenarios, namely, (i) in the first scenario, the slab ...

Behavior of Cellular Beams with Sinusoidal Openings
AbstractExperimental tests were conducted on full scale cellular beams with sinusoidal openings. The analysis of the experimental results showed two failure modes by the formation of four plastic hinges at the opening corners or by the local instability in the sinusoidal part of the opening.

This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Дослідження напружено – деформівного стану стінки-перемички перфорованої балки з круглими отворами [PDF]
Cellular beams were modeled using Finite Element Method in the SolidWorks2013 software suite and imported into ANSYS Workbench 15.0. The onsidered distribution of stresses in the wall-jumper of a cellular beams is considered.

Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Compact Multi-Wideband Array for Millimeter-Wave Communications Using Squint Beams
Millimeter-wave (mmWave) cellular systems leverage the hybrid analog-digital structure to balance the costs and the capacity performance by using fewer Radio Frequency (RF) chains and the spatial sparsity of the channel.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
