Estimating Transmissivity in One‐Dimensional Heterogeneous Aquifers With Groundwater Head Data: From Time or Frequency Perspectives

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Time series of groundwater head in a semi‐infinite, one‐dimensional confined aquifer due to variable boundary forcing can be decomposed into two signals: head rise from a sudden boundary increase, and head fluctuation from boundary sinusoidal changes.

Review of battery electric vehicle propulsion systems incorporating flywheel energy storage [PDF]

, 2015
The development of battery electric vehicles (BEV) must continue since this can lead us towards a zero emission transport system. There has been an advent of the production BEVs in recent years; however their low range and high cost still remain the two ...

Characterisation of Groundwater Flow in the Deltaic Aquifer‐Aquitard System

Hydrological Processes, Volume 39, Issue 9, September 2025.
This study employs a permanent multilevel groundwater monitoring system to capture high‐resolution, hourly groundwater level fluctuations in a deltaic basin, providing an unprecedented dataset for evaluating groundwater flow dynamics. Fractal behaviours are used to explore the deltaic groundwater flow system.

Thermodynamic Bond Graphs and the Problem of Thermal Inertance [PDF]

, 1982
It is shown that an isolated thermal inertance does not obey the second law of thermodynamics. Consequently, such an element should not be used in physical systems theory.

Monitoring Fracture Hydromechanical Evolution in the Lab and Field Using Unsupervised Metric Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Fractures evolve in time through thermal‐hydraulic‐mechanical‐chemical (THMC) processes that alter their long‐range hydraulic transport properties and modify subsurface behavior and activities. The location of subsurface fractures makes it necessary to use remote sensing techniques such as passive or active seismic monitoring for fracture ...

Design Automation of Complex Hydromechanical Transmissions

, 2013
This thesis proposes an automated methodology for the design of complex multiple-mode hydromechanical transmissions. High fuel prices and strict emission regulations are today drivers of the development of new fuel-efficient drive transmissions for construction machinery. Hydromechanical transmissions have high energy efficiency and a wide torque/speed

Development of 1D Hybrid Hydromechanical Models for Real‐Time Forecasting of Induced Seismicity Rate

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Hydraulic stimulations play an important role in Enhanced Geothermal Systems (EGS) by increasing the permeability of the host rock and facilitating more efficient fluid circulation and heat extraction. However, fluid injection operations are unavoidably accompanied by induced earthquakes.
