“…Since in the engineering practice in most cases this assumption is overly restrictive, the aim of this paper is to fill this gap by proposing a formulation valid for manifold conductors of arbitrary topology. A previous attempt to solve this issue is reported in [6], even though necessary details for such a solution are missing, see Sec. 1.3. Let us assume that the conductors form a combinatorial three-manifold K c and that K = K c ∪K a , where K a represents the insulating region and K the whole computational domain.…”

This paper presents in detail the extension of the -Ω formulation for eddy currents based on higher-order hierarchical basis functions so that it can automatically deal with conductors of arbitrary topology. To this aim, we supplement the classical hierarchical basis functions with nonlocal basis functions spanning the first de Rham cohomology group of the insulating region. Such nonlocal basis functions may be efficiently and automatically found in negligible time with the recently introduced Dłotko-Specogna (DS) algorithm. The approach presented in this paper merges techniques together which to some extent already existed in literature but they were never grouped together and tested as a single unit.

“…As China's aging trend continues to deepen, the number of people with disabilities caused by factors such as age and disease is also increasing, and the issue of how to transport such groups is becoming more prominent [1,2]. Currently, the traditional method of manually carrying patients to stretchers is still used for patient transfer in hospitals, which brings high labor intensity to nursing workers and is prone to secondary injury to patients [3]. Fortunately, various transfer nursing robots have been developed in these years, and a series of studies have been carried out for the analysis of these robots, especially some of the devices that have been clinically proven to be effective [4,5].…”

In response to the low level of automation of the tools used for patient transfer in hospitals and the resulting shortage of nursing personnel, this paper studies the characteristics of existing transfer products and related structural features. A transfer machine based on static transfer is proposed, which can achieve patient transfer between a hospital bed and a stretcher truck. In this paper, the overall structure of the transfer machine has been designed in detail, and the structural design and analysis of important transmission components have been carried out. The finite element strength analysis of the main bearing components has been carried out. Finally, the selection of driving components based on their functions has been carried out. This study provides theoretical and technical support for the development of subsequent transfer machines.

Fluid flow and mixing in an inductively stirred ladle are modeled mathematically. The effect of two modes of electromagnetic stirring on motion is simulated; one produces a predominantly swirling motion (as in mechanical, paddle‐stirred ladle), while the other generates an upwelling, toroidal motion (as in gas‐stirred ladle). Two different ANSYS software programs, namely, Maxwell‐3D and Fluent, are applied to carry out numerical simulations. In the former, 3D Maxwell's equations are solved to estimate, a priori, the distribution of Lorentz force within the melt phase due to the imposed three‐phase, alternating current excitation of copper coils, while in the latter, time‐averaged magnetohydrodynamic (MHD) turbulent flow equations are solved to yield the electromagnetically driven flow field. Model predictions are validated against published results and it is shown that the electromagnetic as well as turbulent‐MHD models developed in this work are robust and perform sufficiently accurately. Finally, numerically predicted results together with relevant published work indicated that at equivalent specific input stirring power and identical vessel shape and volume, mixing is fastest in electromagnetic stirring with a traveling magnetic field (producing an upwelling toroidal motion), followed by mechanical agitation, gas stirring, and electromagnetic stirring with a rotating magnetic field (inducing swirling flow).
