Single Smooth Waveform Command‐Shaping Control of Overhead Crane Systems Utilizing Two‐Stage Acceleration–Deceleration Profile for Short‐Moving Point‐to‐Point Maneuver

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern industrial demand for efficient material handling in confined spaces has driven the need for overhead cranes capable of short‐distance point‐to‐point maneuvers without compromising payload stability. Conventional three‐stage shaper profiles, experiencing acceleration, cruising, and deceleration, become inefficient or infeasible for ...

Colliding gravitational waves and singularities

Colliding gravitational waves and singularities
We have investigated a model of colliding plain gravitational waves, proposed by Szekeres, whose structure of singularities is determined. We have evaluated a total energy of matter as a volume integral of the energy–momentum tensor (EMT), whose contributions arise only at these singularities.

Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Controlling fracture permeability plays a critical role in subsurface energy applications, particularly in geothermal energy production and enhanced carbon sequestration, where regulating fluid flow is essential. The use of microcapsules has become a promising solution to enhance fracture permeability by providing a controlled sealing ...

Managing species, managing connections: Social‐ecological alignment in state forestry

People and Nature, EarlyView.
Abstract Forests are shaped not only by ecological processes but also by the actions and interactions of those managing them. In state‐managed multifunctional forests, forest district managers play a central role in translating policies into practice.
