In recent years, there has been renewed interest in problems of diffraction and radiation of ocean waves around structures, in relation to “green” power generation by Oscillating Water Column (OWC) devices. In this paper we present a first-order analytical solution for the diffraction of ocean waves around a hollow cylindrical shell structure suspended in an ocean of finite depth. By revisiting...

Dielectric Elastomers (DEs) are incompressible rubber-like solids whose electrical and structural responses are highly nonlinear and strongly coupled. Thanks to their coupled electromechanical response, intrinsic lightness, easy-manufacturability and low-cost, DEs are perfectly suited for the development of novel solid-state polymeric energy conversion units with capacitive nature and high-volt...

Progress in optical wireless communication (OWC) has unleashed the potential to transmit data an ultra-fast manner without incurring large investments and bulk infrastructure. OWC includes transmissions three sub-bands; ultraviolet, visible, infrared. This paper discusses installing infrared OWC, known as free space optics (FSO), systems on top of installed radio frequency (RF) networks for out...

An active method of suppressing wind auto-oscillations an overground gas pipeline model is considered, which allows the system to be tuned from resonant frequency by changing its design scheme with help a vibration damping device operating on principle one-way con-nection (OWC). A new mathematical vibrations symmetric form natural proposed. Variants models one and two OWC, located in central sp...

A critical characteristic of most WECs (wave energy converters) is the large peak-to-average power ratio. This poses many challenges to the design of high-efficient PTO (power take-off) systems and, even more importantly, to integrate this form of renewable energy into power grids. The OWC (oscillating water column) WECs are devices whose PTO uses an air turbine as the primary energy converter....

Utilization of new renewable energy can be one solution to the limitations fossil energy. Ocean wave is caused by tides, and this potential utilized as a source electrical in Indonesia, especially East Nusa Tenggara. This ocean power plant uses oscillating water column (OWC) technology. that developed environmentally friendly available every time. paper analyzes amount produced waves using OWC ...

In this work, we aimed at the discrimination of mechanically impaired red blood cells (RBCs) using passive microfluidic approaches. We investigated the impact of the channel geometry on the behavior of healthy RBCs (hRBCs) and thermally rigidified RBCs (T-rRBCs) flowing in (i) a Unique and Long Constriction (ULC) and (ii) a series of Oscillating Width Constrictions (OWC). To confront the two ge...

Most experimental research on land-fixed Oscillating Water Column (OWC) systems assume that the OWC-water wave interaction happens with waves propagate normally towards device. However, angle of incidence can determine performance OWC, in particular period at which device resonates. In this study, an investigation to examine regular, oblique, water a land-fixed, thick-front wall OWC terms its h...

Communication is a key element in applying multi-agent reinforcement learning to wide range of real-world scenarios. We focus on optical wireless communication (OWC), which practical solution be used various real situations where radio not available, such as underwater or lot noise environment. OWC method communicating only with other agents visual using light, unlike wave like mostly assumed e...
