On the implementation of the provisions concerning area-based management tools under the BBNJ Agreement

Abstract As one of the four core components of the Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ Agreement), area-based management tools (ABMTs...

Joint capacity planning and dynamic allocation for container leasing with asymmetric substitution

Container leasing companies maintain a flexible container pool to meet short-term requests from committed customers and the spot market. However, capacity planning and container allocation are complicated by stochastic demand, container returns, and asymmetric substitution betwee...

Multimodel fuzzy predictor-based distributed game-theoretic formation control of underactuated autonomous surface vehicles

This paper investigates a distributed game-theoretic formation control problem for underactuated autonomous surface vehicles (ASVs) with potentially conflicting individual objectives. A distributed game-theoretic formation control framework is developed, in which formation coordi...

Research on deep-sea mining risers damage identification based on Multi-Scale Squeeze-and-Excitation Residual Network

Deep-sea mining risers are critical components connecting the mining vessel to the buffer station. Long-term operation in complex marine environments makes them prone to crack initiation and propagation, potentially compromising structural integrity and operational safety. Early...

Variable-Amplitude Fatigue Life Prediction of SBS-Modified Asphalt Mixtures with Physical Gel Structures

The service life of SBS-modified asphalt mixtures with physical gel structures is strongly influenced by the loading sequence–interaction coupling effects. However, conventional linear models fail to accurately capture the influence of such coupling effects on fatigue life. This...

Experimental study on thermal characteristics of ammonia three-dimensional oscillating heat pipes with different filling ratios

A three-dimensional oscillating heat pipe (3DOHP) transfers heat through both latent heat and sensible heat and features good temperature uniformity, compact channels, and high thermal conductivity. In this work, an ammonia-charged 3DOHP with channels gradually contracting from t...

Research on intelligent design of the layout of tank washing machines in cargo oil tanks based on optimal tank cleaning effect

This study proposes a rapid method for evaluating tank-washing efficiency and optimizing tank-washing-machine layouts using a dynamic pressure-illuminance surrogate framework. Water-jet experiments and numerical simulations established the relationship between wall dynamic pressu...

A Health Belief Model-Based Measurement for Profiling Vulnerability to Brucellosis

Purpose To develop and validate a health belief model-based Brucellosis Health Beliefs Scale (BHBS) and identify belief profiles and demographic correlates. Method From June to December 2021, a cross-sectional survey included 261 convenience-sampled livestock keepers ( M age = 47...

Mixing Mechanism and Geometric Effects of Elbows in Offshore Hydrogen-Blended Natural Gas Pipelines

Leveraging existing subsea natural gas pipelines for hydrogen blending offers a practical route for offshore low-carbon energy transport. However, traditional T-pipes require long distances to achieve uniform mixing conditions, raising the risks of stratification and hydrogen emb...

Utility of the second-order discontinuous Galerkin solvers for environmental modelling applications

Accurate reproduction of hydrodynamic and solute mixing processes within cylinder arrays is vital for many environmental modelling applications. Traditional approaches use a second-order finite volume (FV2) method to solve the two-dimensional (2D) planar Reynolds-Averaged Navier-...

A Review of Internal Flow Fields in High-Pressure Common Rail Injector Nozzles

High-pressure common rail injector nozzles are key components of the fuel-injection system in modern diesel engines. The internal flow state and nozzle-exit flow characteristics directly affect fuel atomization, fuel–air mixing, and combustion performance. This article adopts a s...

Marine Radar Oil Spill Detection Method Based on RBM and Improved Quantum Golden Jackal Optimization Algorithm

Marine ecological systems are severely compromised by oil spill incidents, while oceanic economic growth and public well-being are also put at considerable risk. Therefore, the development of high-efficiency and precise detection techniques for marine pollution prevention and con...

Characterization and molecular dynamics of interfacial adhesion in hydrogenated styrene/polyurethane prepolymer composite-modified asphalt

To address the limitations of conventional polymer modified asphalt, a hydrogenated styrene block polyurethane prepolymer (M-PPU) modified asphalt was developed by incorporating a hydrogenated styrene block into a polyurethane prepolymer (PPU). The preparation process was first o...
