Risks in the design of regional hydrogen hub systems: A review and commentary. [PDF]

Risk Anal
Abstract Early investments in regional hydrogen systems carry two distinct types of risk: (1) economic risk that projects will not be financially viable, resulting in stranded capital, and (2) environmental risk that projects will not deliver deep reductions in greenhouse gas emissions and through leaks, perhaps even contribute to climate change.

Real‐time vibration monitoring and analysis of agricultural tractor drivers using an IoT‐based system

Journal of Field Robotics, Volume 40, Issue 7, Page 1723-1738, October 2023., 2023
Abstract Agricultural tractor drivers experience a high amplitude of vibration, especially during soil tillage operations. In the past, most research studied vibration exposure with more focus on the vertical (z) axis than on the fore‐and‐aft (x) and lateral (y) axes.

Smart water management

River, Volume 2, Issue 1, Page 21-29, February 2023., 2023
Abstract Smart water enables utilities, regulators, and customers to make more timely and informed decisions about how they use and regard their water resources. It has been developed to assist demand management by influencing customer behavior and reducing network leakage, lowering energy consumption, and avoiding deploying assets that are not ...

Seismic Response Analysis of Secondary Lining Polymer Grouting Debonding Repair for Tunnel Construction Based on Parameter Inversion

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
The void phenomenon behind the tunnel lining has become the main cause of tunnel disease, easily triggering tunnel lining structure damage, shedding, water seepage, and other diseases that seriously threaten the normal operation of the tunnel. The void area behind the lining seriously reduces the seismic capacity of the tunnel.

Testing, Analysis and Classification of No-Dig Manhole Rehabilitation Materials

Frontiers in Water, 2021
Gravity flow wastewater collection systems are comprised of sewer pipes and manholes. Failure of a manhole may have catastrophic consequences such as developing a sinkhole in the street and roadway, and at a minimum, wastewater flow will be blocked, and ...

A Novel Hybrid Prediction Model for Hourly Gas Consumption in Supply Side Based on Improved Whale Optimization Algorithm and Relevance Vector Machine

IEEE Access, 2019
Accurate short-term prediction of the natural gas load is of great significance to the operation and allocation of the pipeline network. Because the short-term natural gas load has obvious nonlinearity and randomness, the traditional regression model is ...

Customising flood damage functions to estimate the carbon footprint of flood‐related home repairs

Journal of Flood Risk Management, 2021
Flood damage functions are important tools used to estimate potential damage to the built environment from various types of flood‐related hazard events (e.g., hurricanes, riverine flooding).
