This study presents a numerical investigation of the source aspect ratio (AR) influence on tsunami decay characteristics with an emphasis in near and far-field differences for two initial wave shapes Pure Positive Wave N-wave. It is shown that, when total energy both types kept same, short-rupture more concentrated are likely to be destructive near-field, whereas long rupture dangerous far-fiel...

In this paper, a new non-redundant three-layer peak-to-average power ratio (PAPR) reduction technique is proposed for filter bank multicarrier communication based visible light (FBMC VLC) systems. the technique, FBMC VLC data signal overlapped with two signals. The initial-layer signals are modulated For PAPR reduction, second-layer constructed to decrease large-amplitude signals, while last-la...

In this paper, we propose a novel Maxwell dynamic vibration absorber (DVA) with lever, inerter, and grounded stiffness. Firstly, the governing equation of coupled system is established. The analytical formula amplitude amplification factor primary natural frequencies are derived. There three fixed points in amplitude–frequency response curve system, which independent damping. Then, based on H∞ ...

Target masking is a pervasive problem in radar signal processing: the range sidelobes of waveform’s matched filter response may cause strong target to prevent detection nearby weaker targets. Common solutions sidelobe level reduction for frequency-modulated waveforms result signal-to-noise ratio (SNR) loss. In this correspondence, we propose novel method using pulse diversity reduce while avoid...

in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...
