• Multivector Model Predictive Control (MMPC). control of machine side converters. grid WEC emulator. OWC-based model. Oscillating Water Column (OWC) is one the most well-known wave energy converter (WEC). Typically, OWCs are installed in rocky shores or custom-built breakwaters. However, since profile more favorable an open sea, it can also be a point absorber order to increase extraction. Thi...

A U-shaped oscillating water column (U-OWC) device has been investigated to enhance power extraction by placing the bottom-mounted vertical barrier in front of a conventional OWC. Then, optimal design U-OWC attempted using an artificial neural network (ANN) model. First, analytical model is developed matched eigenfunction expansion method (MEEM) based on linear potential theory. Using model, in...

BACKGROUND Diagnosis of the metabolic syndrome (MS) is crucial for health care practitioners to identify at risk people for early treatment. Visceral obesity may make unnecessary other laborious measures of insulin resistance. The aim of this study was to see whether waist circumference (WC) can predict insulin resistance as well as MS in a group of Iranian elderly. METHODS Out of 94 nondiabe...

Interval-valued hesitant fuzzy set (IVHFS), which is the further generalization of hesitant fuzzy set, can overcome the barrier that the precise membership degrees are sometimes hard to be specified and permit the membership degrees of an element to a set to have a few different interval values. To efficiently and effectively aggregate the interval-valued hesitant fuzzy information, in this pap...

Abstract: We present two control strategies for an oscillating water column-wave energy converter (OWC-WEC) in the time domain. We consider a fixed OWC-WEC on the open sea with an impulse turbine module. This system mainly consists of a chamber, turbine and electric generator. For the time domain analysis, all of the conversion stages considering mutualities among them should be analyzed based ...

Optical Wireless Communications (OWC) networks are becoming more and more popular for delivering broadband traffic since they are introducing significant advantages against the other alternative technologies. Operating wavelengths range from ultraviolet (UV) to the infrared (IR) portion of the electromagnetic spectrum and present significant attenuation from channel impairments. As a result, th...

Fifty-nine stream-water samples and 14 municipal wastewater treatment facility (WWTF) discharge samples in Johnson County, northeastern Kansas, were analyzed for 55 compounds collectively described as organic wastewater compounds (OWCs). Stream-water samples were collected upstream, in, and downstream from WWTF discharges in urban and rural areas during base-flow conditions. The effect of secon...

Oscillating water column (OWC) is an advanced form of wave energy converter (WEC). This study aims at improving the efficiency amended OWC through a novel methodology for simulating several vertical plates within chamber. paper provides numerical investigation considering one, two, three, and four plates. The open field operation manipulation (OpenFOAM) solver verified based on Reynolds-Average...

 Abstract—In this letter, we propose a tuned elliptical Lambertian beam (ELB) model to achieve a higher transmission bandwidth than the conventional circular Lambertian beam (CLB) model for indoor optical wireless communication (OWC) systems. ELB is generated by employing a M × N light shaping diffuser (LSD) and its power distribution is investigated. We firstly derive new expressions of the p...
