This article presents the development of a novel bionic robot, which is inspired by agile and fast mantis shrimp in ocean. The developed robot has ten rigid-flexible swimming feet (pleopods) for propulsion rope-driven spine its body bending. By studying motion trajectory biological shrimp, kinematic gait planning pleopod completed central pattern generator controller applicable to coupled multiple pleopods proposed. experimentally verified effectively simulate enables reach maximum velocity...
The paper presents a combined experimental and theoretical approach to the understanding of hysteresis adhesion contributions rubber friction on dry lubricated rough surfaces. Based proper analysis temperature- frequency-dependent behaviors nonlinear viscoelastic materials such as filler reinforced elastomer materials, master curves for moduli are constructed. It is shown that classical williams-Landel-Ferry equation cannot be applied in its simple form, but needs introduction an energy term...
A layered hybrid lattice structure consisting of a body-centered cubic (BCC) and an N-type with negative Poisson's ratio effect is designed. In order to assess the position number layers in overall on mechanical properties, three kinds structures different positions numbers N-structure are manufactured by using laser powder bed fusion (LPBF) technique. Compression experiments carried out BCC for comparisons. The entire loading process recorded deformation pattern captured. experimental...
The molecular-scale structural changes in polycarboxylic superplasticizer (PCE) can influence dispersion and water retention. Polycarboxylate superplasticizer, synthesized using different methods, may alter water-reducing effects. synthesis of PCE involves creating a novel macromolecular monomer with controllable molecular mass, adjustable lipophilic, hydrophilic moieties, as outlined this study. This article reviews processes for synthesizing polycarboxylates identifies the optimal method...
The layered double hydroxide (LDH) has been practically applied in the field of tribology and materials science due to its unique physicochemical properties, weak bonding, flexible structural composition, adjustable interlayer space. In this work, a series ultrathin composition Ni-Fe LDH samples were prepared via cost-effective room-temperature co-precipitation process. Then, they mechanically dispersed into GTL base oil their lubricating performance tested by four-ball tribometer. It is...
Blood pressure is an important physiological parameter to reflect human vital signs. In order achieve the non-contact dynamic blood acquisition based on ordinary optical camera, a theoretical understanding of functional relationship between and pulse wave signal conduction time. And through imaging photoelectric plethysmography (IPPG), time forehead hand was obtained with camera. First, by recording video Second, real-time values were collected. Finally, time, measurement prediction model...
Aiming at the imbalances of SOC (state charge, SOC) and SOH health, SOH) for battery energy storage system (BESS) in smoothing photovoltaic power fluctuations, a allocation method BESS is proposed. Firstly, hierarchical structure given, including acquisition grid-connected reference double-layer strategy BESS. Secondly, swing door trend algorithm optimized by improved Aquila optimizer devised used to deal with raw obtain signal. Next, dynamic grouping principle considering units devised,...
Back Cover: Article 2200272 by Xin Yang, Pengyu Lv, and their co-workers, demonstrates that hydrophobic polymer entanglements can function as robust crosslinking points to prepare anti-swelling hydrogels with high stiffness. The have cartilage-equivalent compressive modulus strength are nontoxic the cell. Moreover, be processed into various complex shapes direct ink printing, promising for articular cartilage replacement.
In order to investigate the relationship and effect on performance of magnetic modulator among applied DC current, excitation source, loop sensitivity induced voltage detecting winding, this paper measured initial permeability, maximum saturation induction intensity, remanent coercivity, saturated field magnetization curve, permeability curve hysteresis main core 1J85 permalloy based ballistic method. On foundation, employ fitting tool MATLAB; adopt multiple regression method comprehensively...
Structural health monitoring is designed to detect and analyze damage in mechanical, aerospace, industrial structures prevent potential catastrophic failures. The effectiveness of identifying structural faults operational significantly relies on the sensing technology. Multisensory data fusion, as one promising techniques, combines from multiple sensor modalities for reliable accurate fault diagnosis. In this paper, we propose a novel decision-level multisensory fusion approach. This...
Purpose In complex environments, a spherical robot has great application value. When the pendulum is stopped or disturbed, there will be periodic oscillation. This situation seriously affect stability of robot. Therefore, this paper aims to propose control method based on backstepping and disturbance observers for oscillation suppression. Design/methodology/approach analyzes mechanism The model constructed relationship between internal structure sphere analyzed. Based model, authors design...
2D MoS2 with narrow lateral size and thickness distributions was introduced to promote the anti-friction anti-wear properties of bentonite grease (BG) in a state boundary lubrication. Optical microscopy (OM), 3D optical profilers (3D OP), Raman spectrometry (Raman), scanning electron microscope, energy dispersion spectrum (SEM-EDS), X-ray photoelectron spectroscopy (XPS) were applied characterize wear surface GCr15 bearing steel/GCr15 steel contact. It is found that average friction...
This paper introduces the first application of technology pre-stressed steel wire-winding frame in constructing hydrostatic pressure testing equipment for environment simulation deep-sea. In December 2015, a 200 MPa medium size ultrahigh cylinder (0.8 m diameter, 2.5 height) was tested experimentally, and technical indicators met requirements, which operated by institute deep-sea science engineering, CAS Sichuan aerospace industry Chuanxi machine Co., Ltd. Then it provided full ocean depth...
In order to improve the tailings utilization rate and realize full tailings’ filling in Huanggang iron mine Inner Mongolia, a flocculation settlement system was added, which resulted silting consolidation of sand silts. Based on this, reason for deposition caking obtained through analysis, set coarse fine bin proposed. The plant were pumped station by slurry pump. Firstly, with large particle size difference divided into hydrocyclone so that entered No. 1 2 bin. Then, flocculant added...
Abstract The effect of breast cancer heterogeneity on prognosis patients is still unclear, especially the role immune cells in cancer. In this study, single cell transcriptome sequencing data were used to analyze relationship between and prognosis. 14 clusters identified two single-cell datasets (GSE75688 G118389). Proportion analysis showed that NK significantly aggregated triple negative cancer, proportion macrophages was increased primary while B cells, T neutrophils may be involved...
