Polypropylene Nonwoven Fabric Filters Containing Graphene Oxide: A Streamlined Approach to Enhance Ultrafine Particulate Matter Removal

Polymer Engineering &Science, EarlyView.
A simple graphene oxide coating strategy enhanced the ultrafine particulate matter (PM0.1) filtration performance of polypropylene nonwoven filters. The oxygen‐containing functional groups of graphene oxide improved particle capture while preserving low pressure drop and high air permeability.

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Experimental Study on Pressure Oscillation Characteristics of High-speed Air Submerged Jet

Yuanzineng kexue jishu
The steam generator tube rupture (SGTR) accident in a lead-cooled fast reactor (LFR) may lead to the leakage of high-pressure water or steam from the secondary loop into the primary loop containing lead-bismuth eutectic (LBE).

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Flow visualization of submerged jets in narrow channels

, 2009
In order to study the effect of wall on the flow pattern of a submerged turbulent water jet in narrow channels, the flow field was visualized by a laser-induced fluorescence (LIF) system at different Reynolds numbers. Those images showed that flow motion

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly

Interactions between a submerged water jet and a free surface

, 2022
This Final Year Project investigated the interactions between a submerged water jet and a free surface, with the aim of visualising and analysing the flow behaviour of the jet both below and as it approaches the interface between air and water.

Characteristics of breaking coal-rock by submerged jet and its application on enhanced coal bed methane recovery

, 2019
Hydraulic slotting is a technique to enhance coal bed methane (CBM) recovery and prevent gas disasters. The drilling fields are usually arranged in floor roadway rather than roof roadway, but submerged jet effects caused by hydraulic slotting in roof ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

Journal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...
