An overview of techniques of acoustic analysis for the detection of obstructive sleep apnea
(2023-09)
The primary focus of this review article is to
investigate acoustic analysis techniques for detecting
obstructive sleep apnea (OSA). OSA causes the upper
airway to collapse partially or entirely during sleep, which
reduces ...
Aerodynamic performance of smooth selectively superhydrophobic flat plates: A numerical approach
(2023-09)
The interference to fluid flow over a solid surface
is significantly high to such an extent that the fluid in
contact with the surface possesses a null velocity. This
phenomenon is called the no-slip condition. On ...
Implementation of arduino based IOT home automation systems in Sri Lanka
(2023-09)
The deployment of microcontroller-based IoT
home automation systems in Sri Lanka are examined in this
review paper, with an emphasis on the subtopics of home
automation, irrigation automation, waste management and ...
Investigation of trends in multiday extreme rainfall

Preliminary wave energy assessment to setup a breakwater type oscillating water column ocean wave energy converter at Hambantota port, Sri Lanka
(2023-09)
Oscillating Water Column (OWC) is a type of
Wave Energy Converter (WEC) that transforms the energy
of ocean waves into low-pressure pneumatic power.
Subsequently, this pneumatic power is taken out by a turbine
and ...
