We present a three-step inverse model (3SAA) for estimating the inherent optical properties (IOPs) of surface waters from remote sensing reflectance spectra, Rrs(?). The derived IOPs include total (a(?)), phytoplankton (aphy(?)), and colored detrital matter (acdm(?)), absorption coefficients, (bb(?)) particulate (bbp(?)) backscattering coefficients. first step uses an improved neural network ap...

Generalized optical multiple-input multiple-output (GOMIMO) techniques have been recently shown to be promising for high-speed wireless communication (OWC) systems. In this paper, we propose a novel deep learning-aided GOMIMO (DeepGOMIMO) framework systems, where channel state information (CSI)-free blind detection can enabled by employing specially designed neural network (DNN)-based MIMO dete...

In a water-air optical wireless communication (OWC) channel, dynamic ocean waves may significantly deflect the light beam from its original direction, thus deteriorating performance. this letter, tracking system to mitigate wave-induced degradation is experimentally demonstrated. By employing on PAM6 system, maximum of 486% improvement (from 140 Mb/s 820 Mb/s) in throughput realized at 1.2-m ai...

Optical wireless communication (OWC) is considered to be a promising technology which will alleviate traffic burden caused by the increasing number of mobile devices. In this study, novel vertical-cavity surface-emitting laser (VCSEL) array proposed for indoor OWC systems. To activate best beam user, two activation methods are system. The method based on corner-cube retroreflector (CCR) provide...

This paper presents ocean wave energy control using the Aquila optimization (AO) technique. An oscillating water column (OWC)-type converter has been considered that is fitted with a Wells turbine and doubly fed induction generator (DFIG). To achieve maximum power point tracking (MPPT), rotor speed of DFIG must be controlled as per MPPT law. The law designed in such way flow coefficient remains...

Oscillating water column (OWC) devices and oscillating buoys (OBs) are two of the main types wave energy converters (WECs). In this paper a hybrid column-oscillating buoy converter is proposed, which we have named OWCOB. The hinged at outer wall column. As waves propagate through OWCOB, within OWC chamber moves up down, producing air flow to propel turbine. Meanwhile, oscillation OB drives sepa...

With its height-resolved measurements and near global coverage, the CALIOP lidar onboard the CALIPSO satellite offers a new capability for aerosol retrievals in cloudy skies. Validation of these retrievals is difficult, however, as independent, collocated and co-temporal data sets are generally not available. In this paper, we evaluate CALIOP aerosol products above opaque water clouds by applyi...
