The acoustic properties of a compound micro-perforated panel (MPP) absorber array are investigated. consists three parallel-arranged MPP absorbers with different cavity depths. A finite element procedure is used to simulate its behaviors under normal incidence. Experimental studies carried out verify the numerical simulations. Due reactance matching conditions in array, strong local resonance occurs and corresponding absorption dominates. Compared single absorber, requires lower resistance...
In the pursuit of more effective noise control devices, cavity backed micro-perforated panel absorber (CBMPPA) is developed in this study. A CBMPPA differs from conventional (MPP) that MPP by a trapezoidal cavity, which allows vibroacoustic coupling between and cavity. two-dimensional theoretical model established tested both numerically experimentally. Based on verified model, sound absorption performance investigated numerically. Results show shape backing can significantly alter...
To evaluate corn quality quickly, the feasibility of near-infrared spectroscopy (NIRS) coupled with chemometrics was analyzed to detect moisture, oil, protein, and starch content in corn. A backward interval partial least squares (BiPLS)-principal component analysis (PCA)-extreme learning machine (ELM) quantitative model constructed based on BiPLS conjunction PCA ELM. The selection characteristic spectral intervals accomplished by BiPLS. best principal components were determined prediction...
In this paper, the thermodynamic model of polyacrylonitrile (PAN) solution is constructed with different conditions, according to Flory theory in most suitable way. The interaction parameters associated PAN system were measured by modified Rudin and conventional equilibrium solvation method. was found have upper critical temperature. Temperature viscosity are also shown be constant under θ conditions. DMSO/PAN/ethanol stable DMF/PAN/H2O least through modeling. mechanism phase separation...
A previous theoretical study [L. Huang, J. Acoust. Soc. Am. 119, 2628–2638 (2006)] shows that, in a duct, simply supported plate covering side-branch rigid cavity can function effectively as wave reflector over broad range of low to medium frequencies. In this study, analytical formulation is extended the boundary condition clamped plate, which easier implement practice. The model tested experimentally using balsawood, has very high stiffness mass ratio. spectral peaks and shapes measured TL...
