Abstract High‐entropy oxides, with their diverse compositions and entropy‐stabilized structures, have emerged as promising candidates for sodium‐ion battery cathodes. However, phase transitions in these materials are highly sensitive to the specific transition metal composition, effective design strategies remain underdeveloped. Herein, a six‐element high‐entropy layered oxide cathode, O3‐Na 0.9 Ni 0.3 Fe 0.1 Zn Cu 0.05 Mn Ti 0.15 O 2 , is reported which incorporation of not only alters...
Abstract We propose an enriched finite element formulation to address the computational modeling of contact problems and coupling non-conforming discretizations in small deformation setting. The displacement field is augmented by terms that are associated with generalized degrees freedom collocated along interfaces or surfaces. enrichment strategy effectively produces node-to-node discretization can be used any constraint enforcement criterion; this demonstrated both multi-point constraints...
<p indent="0mm">The self-developed China space station core module manipulator is the first large-sized robot system with Chinese characteristics. In system, undertakes important tasks, including large transposition and auxiliary docking, support for astronauts’ extravehicular activities, status check, equipment installation or maintenance. It highly integrated difficult to implement, involving many disciplines, such as mechanics, electricity, thermals, optics, control. This paper introduces...
Abstract This article investigates the issue of observer‐based sliding mode control for Markovian jump systems suffer from actuator attacks through an adaptive technique. During communication channel plant output to estimator, a dynamic event‐triggered generator is employed in enhancing efficiency. Taking consideration malicious on actuator, compensator put forward security purposes. By designing state observer, desired dynamics can be derived based integral‐type surface. Further,...
Abstract In this work, an object‐oriented geometric engine is proposed to solve problems with discontinuities, for instance, material interfaces and cracks, by means of unfitted, immersed, or enriched finite element methods (FEMs). Both explicit implicit representations, such as entities level sets, are introduced describe configurations discontinuities. The designed in way consists several modules. For efficiency, a ‐d tree data structure that partitions the background mesh constructed...
This paper investigated the resistance performance of catamarans in calm water using RANS (Reynolds averaged Navier-Stokes) method and overlapping grid technology. The uncertainty numerical calculation was analyzed to verify its feasibility, feasibility accuracy process were confirmed through model tests. study impact various factors, including panel spacing, draft, appendages, on water. Results showed that, for a given span, increasing spacing between two plates decreased interference...
In this paper, the resistance performance of catamaran in calm water was studied based on RANS method and overlapping grid technology. The uncertainty numerical calculation analyzed to verify feasibility calculation. accuracy were verified model test results. effects different panel spacing, draft appendages carried out. It found that increase spacing beneficial diffusion wave making between two panels catamaran, which could reduce interference hull, then reduced its pressure resistance,...
In this paper, the positional accuracy and contact force index requirements of manipulator are analyzed according to tolerance space screwing. An position-based in Cartesian impedance control strategy based on friction identification compensation is proposed. By using joint torque improve system precision setting desired position end point force, solves contradiction between requirement during operating. The algorithm designed dynamics model, stability analysis given. correctness verified by...
Abstract Six NHC Ru complexes are prepared by etherification of 4‐substituted 2‐(propen‐1‐yl)phenols with either ethyl alpha‐bromopropionate or 2‐bromo‐gamma‐butyrolactone followed reaction Grubbs 2nd generation catalyst in the presence CuCl.
Effects of heat treatment including annealing, especially recovery and recrystallization interannealing on properties hard drawn aluminum wire were discussed. The experimental results showed that annealing influence aluminium significantly. Recovery at 180oC improved its electrical conductivity by 0.5% (IACS) without strength decrease. Interrecrystallization 300oC increased the 1.5%IACS, but reduced to 140MPa. Precipitation supersaturated Fe from solid solution during process contributed...
