Vortex acoustic fields are an emerging particle manipulation technique that gathers particles at a central zero-pressure point. Acoustic carrying orbital angular momentum (OAM) reflected by hard boundaries, limiting their application within capillaries for aggregation of bioparticles in the cell analysis and biomolecule purification. We report design generating standing wave vortex capillary investigate its effects on aggregation. The uses spiral phase helical tube placed outside to transfer...
Arrays of nanostructure that are capable broadband antireflection and light trapping properties implemented in photovoltaic photonic devices. However, most the existing films have been hindered by a complicated fabricated method structurally rigid. Here, we report simple preparation for self-erasable nanocone using surface replication method. with sub-100 nm features could be replicated easily on shape memory polyvinyl alcohol (PVA) film, erased thermal stimulation. The reflectivity film can...
Curved multi-frame box-girder bridges with hinges are widely used in the United States due to large spanning capacity, construction simplification and cost economy. This type of bridge frequently has characteristics column height asymmetry, adjacent frames vibrating discrepancy. The combination curved shape random seismic excitation angles could aggravate irregularity structural response. In this study, an OpenSees model is established for example bridge, hinge taken as a key component...
Multiframe PC box‐girder bridge with intermediate hinges is a kind of having complex structural characters, which very quintessential in California. In this study, typical was adopted to establish nonlinear dynamic model through OpenSees platform. Intermediate hinge and inhibiting devices it were elaborately simulated. Meanwhile, pushover analysis used reinstate specimen column test, has the similar ratio reinforcement bridge, hysteretic parameters longitudinal steels inside columns...
Abstract Under the action of natural wind, shielding ring tension string UHVDC transmission line is prone to low frequency vibration, and long-term vibration may lead fatigue damage ring, threatening safe operation line. In this paper, modal test carried out by using hammering method, frequencies mode shapes are mastered. Combined with analysis wind speed direction in engineering site, it shown that vortex induced caused low-speed continuous stable along
