The pseudo-static tests and pseudo-dynamic substructure tests have been conducted to study the characteristics and design parameters of the dampers. The results of 11 sets of coupling beam dampers tested under pseudo-static loads are discussed in this paper and one optimum type of...
Design and Fabrication of Diffractive Optical Element-Microlens with Continuous Relief Fabricated On-Top of Optical Fibre by Focused Ion Beam for Fibre-to-... The purpose of this work is to demonstrate efficient optical coupling between a single mode fibre and a waveguide (LiNbO-APE) using a di...
design is desired, the optimization task is to seek the maximum value of the first natural frequency. However, the purpose of this study was to reveal the reason that bamboo does not easily fail at the its root from dynamics. The stem of a woody plant was regarded as a solid beam. ...

The simula- tion results have the potential for optimizing the perfo- ration design layout in hydraulic fracturing operations. In summary, much research has been conducted on the factors that influence the development of single-hole hydraulic fracturing. However, dual hole synchronous hydraulic ...
The interfacial shear coupling (ISC) governs the relative in-plane deformations of layered two-dimensional (2D) van der Waals (vdW) materials, which is significant for both the fundamental theory of solid mechanics and the stability design of 2D devices. Here we study the representative ISC of ...
Methods Sample fabrications. The 3D MMs were fabricated with a focused-ion-beam (FIB) irradiation-induced folding technique on self-supporting Au films25. Specifically, Si substrates were cleaned and spin-coated with a 1.2 μm layer of S1813 photoresist, then baked at 115 °C ...
First, we design an array with isolated element. For this example we choose the center of the X-band as our design frequency. Get freq = 10e9; vp = physconst('lightspeed'); lambda = vp/freq; In [4], it was discussed that the central element of a 5 X 5 array, whe...
For example: Calculate the array pattern of the rectangular array of dipoles in the x-y plane with a spacing of half-lambda fc = 1e9; lambda = physconst("lightspeed")/fc; az = -180:0.1:180; el = -90:0.1:90;%% Elementd = design(dipole,1e9); ...
TEM images are acquired using an FEI Morgagni M268 instrument with a Gatan Orius CCD camera, at an electron beam energy of 100 keV. STEM images are acquired using an FEI Nova NanoSEM 450 instrument, at an electron beam energy of 30 keV. Optical microscopy Scattering measurements are perf...
