In recent years, there has been a growing interest in the use of single-photon avalanche diode (SPAD) optical wireless communication (OWC). The SPAD operates Geiger mode and can act as photon counting receiver obviating need for transimpedance amplifier. Although provide higher sensitivity compared to traditional linear photodetectors, it suffers from dead-time-induced nonlinearity. To improve ...

Future 6G wireless networks will once again have to raise the performance in most technology domains by a factor of 10–100. Depending on application, future requirements include peak data rates 1 Tb/s per user, 0.1 ms latency, less than one out million outage, centimeter accurate positioning, near zero energy consumption at device, and operation different environments including factories, vehic...

An assessment of personality and psychological distress of people living with delusional halitosis attending Oral Wellness Centre (OWC) at the University of Benin Teaching Hospital, Benin City over a six-month period was undertaken. Five (5) patients with age range of 18-30 years and a mean age of 24 years (SD = 4.47) were included in the study. These individuals manifested multiple symptoms as...

The spot-diffusing technique provides better performance compared to conventional diffuse system for indoor optical-wireless communication (OWC) system. In this paper, the performance of an OW spot-diffusing communication system using Neuro-Fuzzy (NF) adaptive multi-beam transmitter configuration has been proposed. The multi-beam transmitter generates multiple spots pointed in different directi...

Motivated by the looming radio frequency (RF) spectrum crisis, this paper aims at demonstrating that optical wireless communication (OWC) has now reached a state where it can demonstrate that it is a viable and matured solution to this fundamental problem. In particular, for indoor communications where most mobile data traffic is consumed, light fidelity (Li-Fi) which is related to visible ligh...

As a system using a conventional unidirectional air turbine in oscillating water column (OWC) based on a wave energy plant, a twin unidirectional impulse turbine topology has been suggested in previous studies. However, the average efficiency of the suggested twin turbine is considerably lower than that of a conventional unidirectional turbine in this topology because reciprocating air flow can...
