Optical Wireless Communication (OWC) otherwise known as Free Space Optical (FSO) communication is a future ready wireless technology which solves many communication bottlenecks at very low implementation cost. The performance of FSO is sensitive towards the atmospheric turbulence. By using a proper error correction code this effect can be mitigated. This paper deals with the basic concept of FS...

BACKGROUND Research has shown that improving well-being using positive mental health interventions can be useful for predicting and preventing mental illness. Implementing online interventions may be an effective way to reach young people, given their familiarity with technology. OBJECTIVE This study will assess the effectiveness of a website called the "Online Wellbeing Centre (OWC)," design...

The high security of optical phased array (OPA) signals is an important requirement for OPA-based wireless communication (OWC). We propose a method improving the OWC systems using optically injection-locked (OIL) semiconductor lasers. theoretically demonstrate amplitude and phase modulation OIL-OPA elements by controlling injection-locking parameters OIL When Taylor window function applied as p...

The identification of the Oil/Water Contact (OWC) in a hydrocarbon reservoir is crucial for determination its volume and it also important detailed petrophysical calculations. Estimation OWC requires Free Water Level (FWL). Routine practice oil gas industry involves drilling multiple discovery wells since undulation rock layers confining does not generally enable single well to intercept water ...

The nonlinear distortion introduced by the dead time strongly limits throughput of highly sensitive SPAD-based optical wireless communication (OWC) systems. Optical OFDM can be employed in systems with SPAD arrays to improve spectral efficiency. In this work, a theoretical performance analysis OWC system asymmetrically-clipped (ACO-OFDM) is presented. impact nonlinearity on investigated. additi...

Few data are available on net productivity rates in Laurentian Great Lakes wetland communities. We used several methods (Licor photosynthesis system and various radiotracer methods) to estimate midsummer carbon photoassimilation rates among important phytoplanktonic and aquatic macrophyte assemblages in Old Woman Creek National Estuarine Research Reserve (OWC) on Lake Erie near Huron, OH, durin...

In this paper, we propose an orthogonal frequency division multiplexing (OFDM)-based generalized optical quadrature spatial modulation (GOQSM) technique for multiple-input multiple-output wireless communication (MIMO-OWC) systems. Considering the error propagation and noise amplification effects when applying maximum likelihood ratio combining (ML-MRC)-based detection, further a deep neural net...

In this paper, we consider an intensity modulated direct detection multiple-input-multiple-output optical wireless communication (IM/DD MIMO-OWC) system, where the channel coefficients are assumed to be completely known at the receiver. For such a system, since both the transmitted signals and the channel coefficients are nonnegative, the full rank condition on the unique identification of the ...

To develop novel wave energy conversion devices (WECDs) with excellent performance, the relative height and pressure in chambers of square curved oscillating water column (OWC) WECDs were compared through physical model tests, effects regular incident factors, opening length, width, chamber volume on aerodynamic performance capture efficiency (WECE) investigated.
