Presently, among the global ocean energy technologies, most conventional one is wave power generation device based on oscillating water column (OWC) converter. Given fluctuation and randomness of waves complexity current grid, dynamic response grid connections must be considered. Furthermore, considering characteristics converter, this paper proposed an adaptive intelligent controller (AIC) for...

Integrating multi-type Wave Energy Converters (WECs) enables wave energy to be extracted from multiple harvesting manners simultaneously, which presents a more competitive conversion technology. In this study, an Oscillating Water Column (OWC) and Buoy (OB) are combined devise hybrid WEC system that serves as floating breakwater. The two devices aligned in line with the incident direction, wher...

The purpose of this paper is to prove a general fixed point theorem by altering distance for two owc pairs hybrid mappings and to reduce the study of fixed points of pairs of mappings satisfying a contractive condition of integral type at the study of fixed point in metric spaces by altering distances satisfying an implicit relation, which generalize some results from [1], [6], [9], [21], [27] ...

This paper utilizes ANSYS-AQWA hydrodynamic simulation analysis software (2022 R2) to investigate the wave dissipation performance of an Oscillating Water Column (OWC) perforated floating breakwater under irregular conditions. The study examines effect spacing, width OWC opening, water depth, incident angle, and significant height on breakwater. results indicate that OWC-perforated surpasses si...

Understanding Indoor Airflow Patterns (IAPs) helps control air contaminants in large naturally ventilated buildings (NVBs). However, the effect of random and unpredictable changes outdoor wind conditions (OWC) is a major contributor to variation IAPs NVBs, making IAP uncontrollable.

In this paper, we analyze the throughput and reliability of an indoor optical wireless communication (OWC)-based Internet Things (IoT) system based on Slotted ALOHA (SA) where IoT devices exchange data with access point (AP). Assuming that OWC receiver at AP exploits capture effect, derive error probability decoding a short-length packet originates from randomly selected device in presence inte...
