In this note, we comprehensively characterize the proximal operator of the $\ell_{1,q}$-norm with $0\!<\!q\!<\!1$ by exploiting the well-known proximal operator of the $\ell_q$-norm on the real line. In particular, much more explicit characterization

In response to the operational requirement of salvage of wreck and cargo without damage during the salvage process, a new non-contact large tonnage integral salvage technology and equipment, i.e., the curved beam system, has been designed and develop

In this paper, a method for analyzing the dynamic characteristics of the sunken ship salvage system based on the accurate time history of the seabed resistance force is proposed. The simulation of a typical case preliminarily clarifies the complex in

Based on the time domain simulation of the dynamic response of the wreck salvage system in the off-bottom stage, this paper proposes a semi-quantitative safety assessment method for this process, aiming to summarize all motion modes of the salvaging

In the deep rock excavation process, the rock will produce deformation and damage under multiple dynamic disturbances, while there is also unrecoverable time-dependent deformation. In order to research this deformation characteristic, a sine wave dis
