Multi-Antenna GNSS-Accelerometer Fusion Attitude Correction Algorithm for Offshore Floating Platform Displacement Monitoring.

In order to solve the problem of fixed ambiguity and decreased accuracy in GNSS displacement monitoring of the offshore floating platforms, an attitude correction algorithm based on the fusion of a multi-antenna GNSS and an accelerometer was proposed using the Kalman filtering method. The algorithm was validated on a physical simulation platform and a real offshore floating platform. The results indicate that this fusion method effectively compensates for the loss of high-frequency displacement information caused by low GNSS sampling rates, improves situations in which the fusion effect deteriorates due to attitude changes, and enhances the accuracy of GNSS and accelerometer fusion monitoring through offshore buoy testing.

PLC based laser scanning system for conveyor belt surface monitoring.

This paper presents the design, implementation, and testing of an advanced conveyor belt surface monitoring system, specifically engineered for harsh and complex industrial environments. The system integrates multiple cutting-edge technologies, including programmable logic controllers (PLC), laser scanning, industrial-grade cameras, and deep learning algorithms, particularly YOLOv7, to achieve real-time, high-precision monitoring of conveyor belt conditions.

Janus structural TaON/Graphene-like carbon dual-supported Pt electrocatalyst enables efficient oxygen reduction reaction.

Developing carbon-supported Pt-based electrocatalysts with high activity and long-durability for the oxygen reduction reaction (ORR) is an enormous challenge for their commercial applications due to the corrosion of carbon supports in acid/alkaline solution at high potential. In this work, a Janus structural TaON/graphene-like carbon (GLC) was synthesized via an in-situ molecular selfassembly strategy, which was used as a dual-carrier for platinum (Pt). The as-obtained Pt/TaON/GLC presents high half-wave potential (0.

Oxygen Vacancy Induced Atom-Level Interface in Z-Scheme SnO/SnNbO Heterojunctions for Robust Solar-Driven CO Conversion.

The modulation of Z-scheme charge transfer is essential for efficient heterostructure toward photocatalytic CO reduction. However, constructing a compact hetero-interface favoring the Z-scheme charge transfer remains a great challenge. In this work, an interfacial Nb-O-Sn bond and built-in electric field-modulated Z-scheme O-SnO/SnNbO heterojunction was prepared for efficient photocatalytic CO conversion.

Weakened Crystalline SnNb O for Enhanced Performance in Photocatalytic H Production and CO Reduction.

Low crystalline photocatalysts with unsaturated active sites, such as oxygen vacancy (O ), is reported to exhibit enhanced adsorption and activation of oxygen-containing small molecules, such as H O and CO , thus boosting the activity in photocatalytic H evolution and CO reduction. However, numerous low-crystalline photocatalysts show unsatisfactory stability due to the easily repaired surface O . Herein, three SnNb O with different crystallinity were prepared by hydrothermal approach with similar precursors.

Efficient remediation of heavily As(III)-contaminated soil using a pre-oxidation and stabilization/solidification technique.

The high mobility of As(III) makes it difficult to remediate heavily As(III)-contaminated soil. A novel remediation technique that combines pre-oxidation and stabilization/solidification (PO + S/S) is proposed in this study to remediate heavily As(III)-contaminated soil. After oxidizing As(III) in the contaminated soil using Fenton's reagent, FeCl·6HO was used as a chemical stabilizing agent to reduce the toxicity and mobility of As.

The effect analysis of strain rate on power transmission tower-line system under seismic excitation.

The effect analysis of strain rate on power transmission tower-line system under seismic excitation is studied in this paper. A three-dimensional finite element model of a transmission tower-line system is created based on a real project. Using theoretical analysis and numerical simulation, incremental dynamic analysis of the power transmission tower-line system is conducted to investigate the effect of strain rate on the nonlinear responses of the transmission tower and line.
