Negative Poisson's ratio (NPR) metamaterials exhibit outstanding advantages in load-bearing, energy absorption, and buffering, with broad prospects for applications aerospace, shipbuilding, related fields. However, the highly nonlinear performance-parameter relationship of NPR makes optimisation design targeting special mechanical properties challenging time-consuming. This paper proposes a multi-fidelity constrained sequential method based on lower-confidence-bound criterion (MF-CLCB)...
Abstract This article investigated how collectivism-oriented human resource management can influence on innovation performance through team reflexivity and psychological safety. Using a sample of 200 research-oriented teams in Chinese universities, the empirical results clearly indicate that is beneficial to teams’ performance. The mediating model show safety mediate relationship between implications for researchers practitioners are also discussed.
Thin-walled cylindrical shells are widely used in industries, such as the main parts of aircrafts, rockets, and submarines. Except for meeting load-bearing capacities, structures must also have good vibration acoustic performances. However, it is still a challenge to control multi-modal at low frequencies. This study explores cutting-edge local resonant piezoelectric metamaterials low-frequency shells. A novel meta-shell with materials digital circuits was proposed, multi-resonance transfer...
In this paper, the Eulerian–Lagrangian method and Tabakoff erosion model are used to study solid–liquid two-phase flow in a Francis turbine. Through analysis of overall pattern, particle flow, concentration, wear bladeless area unit under different guide vane openings, influence runner radial gap on surrounding field characteristics openings is revealed. The results show that smaller opening vane, greater vortices pattern distribution runner. hydraulic turbine with optimal smallest....
Abstract In this paper, a multi-fidelity Bayesian optimization approach is presented to tackle computationally expensive constrained multi-objective problems (MOPs). The proposed consists of three-stage framework designed search for promising candidate points. the first stage, an acquisition function identify feasible solution if none are available in current set sampling Subsequently, new weighted expected hypervolume improvement developed find better solutions. third lower confidence bound...
A procedure was developed for the determination of polyethylene glycol monoester acrylate (PEGMA) and diester (PEGDA) by reversed-phase high performance liquid chromatographic (RP-HPLC) with UV detector. Sample well separated on an SinoChrom ODS-BP (C-18) column (200 × 4.6 mm i.d., 5 μm) mobile phases composed acetonitrile-phosphate buffer solution (0.05 mol · L−1 pH = 6.86) in ratio 42:58 (v/v). The PEGMA PEGDA were detected detector at 205 nm, quantitatively analyzed external standard...
This paper presents an algorithm structure for active noise control (ANC) system based on improved equation error (EE) model that employs the offline secondary path modeling method. The of a compressor in gas station is taken as example to verify performance proposed ANC system. results show improves reduction and convergence speed compared with other typical systems. In particular, it achieves 28 dBA attenuation at frequency about 250 Hz mean square (MSE) −20 dB.
High-dimensional high-frequency continuous-vibration control problems often have very complex dynamic behaviors. It is difficult for the conventional methods to obtain appropriate laws from such systems suppress vibration. This paper proposes a new vibration controller by using reinforcement learning (RL) and finite-impulse-response (FIR) filter. First, simulator with enough physical fidelity was built system. Then, deep deterministic policy gradient (DDPG) algorithm interacted find...
Abstract In the extraction system of ethyl acetate and NaCl aqueous solution, partition coefficients polyethylene glycol mono‐acrylate (PEGmA) di‐acrylate (PEGdA) varied with temperature concentration solution were studied. The best separation condition PEGmA PEGdA was determined on that basis. Results testing showed sharply increased rising temperature. Since incremental degrees different from each other, ratio coefficient ( K / ) reached a maximum under conditions 20 °C 5 mol L −1 NaCl....
Acoustics Willis media, known as bianisotropic acoustic incorporate additional coupling between pressure and velocity momentum volumetric strain in their constitutive equation. The extra terms have a significant influence on wave behavior. In this paper, the unusual phenomena relevant to interfaces homogeneous media are theoretically studied. We show that offer more flexible control front energy flow when waves transmitted through an interface. Different from traditional fluid, support edge...
At present, the majority classrooms of university teachers take 'classroom, teacher and computer' as center, using blackboard projection to impart knowledge. It is a common phenomenon for just read out loud from computers give lessons with lack paying close attention individual differences effective study. necessary achieve 'concept reconstruction' classroom future talents cultivation teaching reform. The should include contextuality, openness, intelligence, interactivity cloud five...
Initiating a strategic development plan is necessary for universities to be managed scientifically; university's includes both the educational philosophy and orientation as determined by university, including future reallocation of resources measures their integration. The experience Australian New Zealand tells us that scientific rational university can promote rapid university; on contrary, with an unscientific irrational plan, cannot put into practice, or results in waste resources,...
