As a kind of sustainable energy source, ocean wave has always attracted attention. Because the characteristics multi-directions and low-bandwidth, harvesting been difficult. To harvest broadband in multiple directions improve power generation efficiency, we present multi-modal device by using cross beam structure. In this device, efficient multi-frequency vibration achieved structure high effic...

In this paper, a simple and reproducible approach for attaching the multi-wall carbon nanotubes (MWNTs) to the apex of the atomic force microscope probe has been proposed. For this purpose, the dielectrophoresis method was applied due to its simple performance, cheapness and reliability. In this method, various parameters such as voltage, frequency, concentration of carbon nanotubes solution an...

Abstract Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion has been attracting much attention to improve the bit error rate (BER) performance of DS-CDMA by obtaining the frequency diversity gain. In the uplink case, however, since MMSE-FDE cannot transform the channel into a frequency-flat channel, multi-access interference (MAI) (or called multi-user i...
