Analytical Study of Reinforced Concrete Beams Tested under Quasi-Static and Impact Loadings

Applied Sciences, 2019
During dynamic events (such as impact forces), structures fail to absorb the incoming energy and catastrophic collapse may occur. Impact and quasi-static tests were carried out on reinforced concrete beams with and without externally bounded sprayed and ...

Recent Progress and Opportunities in Oxide Semiconductor Devices for In‐Memory and Neuromorphic Computing

Advanced Electronic Materials, EarlyView.
This review surveys oxide‐semiconductor devices for in‐memory and neuromorphic computing, highlighting recent progress and remaining challenges in charge‐trap, ferroelectric, and two‐transistor devices. Oxide semiconductors, featuring ultra‐low leakage, low‐temperature processing, and back‐end‐of‐line compatibility, are explored for analog in‐memory ...

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

VAE+DDPG: An Attention‐Enhanced Variational Autoencoder for Deep Reinforcement Learning‐Based Autonomous Navigation in Low‐Light Environments

Advanced Intelligent Systems, EarlyView.
Variational Autoencoder+Deep Deterministic Policy Gradient addresses low‐light failures of infrared depth sensing for indoor robot navigation. Stage 1 pretrains an attention‐enhanced Variational Autoencoder (Convolutional Block Attention Module+Feature Pyramid Network) to map dark depth frames to a well‐lit reconstruction, yielding a 128‐D latent code ...

Application of nanofiber composites in improving shear resistance and durability of buildings

Measurement: Sensors
In order to improve the shear performance of reinforced concrete beams and improve the shear bearing capacity of concrete beams, the author proposes a scheme based on flax fiber cloth to strengthen the shear performance of reinforced concrete beams, by ...

Markov chain modeling of evolution of strains in reinforced concrete flexural beams

Materiales de Construccion, 2012
From the analysis of experimentally observed variations in surface strains with loading in reinforced concrete beams, it is noted that there is a need to consider the evolution of strains (with loading) as a stochastic process.

Tinjauan Kuat Lentur Balok Beton Bertulang Dengan Tambahan Tulangan Baja Menyilang Pasca Bakar Dengan Berbagai Variasi Waktu [PDF]

, 2015
Heating in concrete due to fire would result in a fundamental change of its nature. The concrete will be cracked, spalled, and loss of its strenght. Loss of strenght occurs because the chemical composition changes gradually in the cement paste.

Physical Reservoir Computing for Smart Manufacturing of PCB Using Crystallinity‐Controlled HfO2 Memristor for Reservoir

Advanced Intelligent Systems, EarlyView.
We address multilayer PCB anomaly detection for smart manufacturing by physical reservoir computing with HfO2‐based memristors. Crystallinity‐tuned HfO2 suppresses ferroelectricity while preserving the high‐k insulating state and confers strong short‐term memory.
