Deep Underground Science and Engineering, EarlyView.This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

CAAI Transactions on Intelligence Technology, EarlyView., 2023 Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.

Lagrangian Approach to Quantum Mechanics
, 2000 The Lagrangian approach of Dirac is presented in a complete form. This suggests to identify the Schr dinger equation as the Euler-Lagrange equation rather than the Hamiltonian operator equation.

Noncommutative Effects on the Fluid Dynamics and Modifications of the Friedmann Equation
Advances in High Energy Physics, 2018 We propose a new approach in Lagrangian formalism for studying the fluid dynamics on noncommutative space. Starting with the Poisson bracket for single particle, a map from canonical Lagrangian variables to Eulerian variables is constructed for taking ...

Generalized Lagrangian Path Approach to Manifestly-Covariant Quantum Gravity Theory
Entropy, 2018 A trajectory-based representation for the quantum theory of the gravitational field is formulated. This is achieved in terms of a covariant Generalized Lagrangian-Path (GLP) approach which relies on a suitable statistical representation of Bohmian ...

Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...
