We analyze the performance of a piezoelectric bimorph in flexural mode for scavenging ambient vibration energy and evaluate dependence upon physical geometrical parameters model bimorph. The analytical solution motion shows that output power density increases initially, reaches maximum, then decreases monotonically with increasing load impedance, which is normalized by parameter simple combination structure, bimorph, frequency vibration, underscoring importance circuit to have impedance...
In this paper, we present a novel analytic approach to solve the buckling instability of Euler-Bernoulli columns with arbitrarily axial nonhomogeneity and/or varying cross section. For various including pinned-pinned columns, clamped and cantilevered governing differential equation for flexural rigidity is reduced Fredholm integral equation. Critical load can be exactly determined by requiring that resulting has nontrivial solution. The effectiveness method confirmed comparing our results...
Abstract To compare spectacle lenses with highly aspherical lenslets (HAL) versus defocus incorporated multiple segments (DIMS) on myopia progression control in 1 year. This retrospective cohort study involved data from children prescribed HAL or DIMS Guangzhou Aier Eye Hospital, China. address the discrepancy that some followed up at less than more year, standardized 1-year spherical equivalent refraction (SER) and axial length (AL) changes baseline were calculated. The mean differences...
Abstract: Biological characteristics of western flower thrips, Frankliniella occidentalis (Pergande) (Thysan., Thripae), were investigated on excised leaves five vegetables: cabbage ( Brassica oleracea L. var. Jingfeng 1), cucumber Cucumis sativus Zhongnong 8), capsicum Capsicum annuum Zhongjiao 5), kidney bean Phaseolus vulgaris Gonggeizhe) and tomato Lycopersicon esculentum M. zhongza 9). The developmental time from egg to adult the cucumber, cabbage, bean, leaf was 9.22 ± 0.13, 10.19...
This letter presents a theoretical treatment of Timoshenko [S. Timoshenko, Philos. Mag. 41, 744 (1921)] beams, in which the influences shear deformation, rotary inertia, and scale coefficient are taken into account. Based on nonlocal elasticity theory, coupled equations for transverse deflection rotation cross section derived. Free vibration several typical beams is analyzed. Explicit expressions modal shapes presented. Natural frequencies evaluated free simply supported clamped cantilever...
