Hydraulic turbines contribute to 60% of renewable energy in the world; however, they also entail some adverse effects on aquatic ecology system. One such effect is their excessive noise and vibration. To minimize this effect, one most effective feasible solutions modify design turbine rotor blade by introducing a skew. In study, two 0.3-meter tidal with 0-degree (no-skewness) positive 90-degree...

BACKGROUND Although rotors have been considered among the drivers of atrial fibrillation (AF), the rotor definition is inconsistent. We evaluated the nature of rotors in 2D and 3D in- silico models of persistent AF (PeAF) by analyzing phase singularity (PS), dominant frequency (DF), Shannon entropy (ShEn), and complex fractionated atrial electrogram cycle length (CFAE-CL) and their ablation. ...

BACKGROUND The pivot is critical to rotors postulated to maintain atrial fibrillation (AF). We reasoned that wavefronts circling the pivot should broaden the amplitude distribution of bipolar electrograms because of directional information encoded in these signals. We aimed to determine whether Shannon entropy (ShEn), a measure of signal amplitude distribution, could differentiate the pivot fro...

BACKGROUND Molecular rotors are fluorescent molecules that exhibit viscosity-dependent fluorescence quantum yield, potentially allowing direct measurements of cell membrane viscosity in cultured cells. Commercially available rotors, however, stain not only the cell membrane, but also bind to tubulin and migrate into the cytoplasm. We synthesized molecules related to 9-(dicyanovinyl)-julolidine ...

A numerical hydrodynamic performance analysis of the pitch-type multibody wave energy converter (WEC) is carried out based on both linear potential flow theory and computational fluid dynamics (CFD) in unidirectional condition. In present study, Salter’s duck (rotor) chosen for analysis. The basic concept WEC rotor, which nods when pressure-induced motions are phase, that it converts kinetic ...

The present study investigates the impact of various factors affecting coal-fired power plant economics of 210 MW subcritical unit situated in north India for electricity generation. In this paper, the cost data of various units of thermal power plant in terms of power output capacity have been fitted using power law with the help of the data collected from a literature search. To have a realis...

Ventricular fibrillation (VF) is the main immediate cause of sudden, unexpected cardiac death. It appears in the electrocardiogram (ECG) as an aperiodic, irregular rhythm, giving the impression that electrical activation of the ventricles is highly complex and disordered. Unfortunately, despite many years of research and speculation, it has still not been possible to confirm or reject that idea...

embedded orthogonal transition matrix to the a-ertended upper Hessenberg form, and (iii) factorization of this new form into Givens (planar) rotations. Appropriately interconnecting the rotors leads to the pipelined orthogonal filter structure. As a consequence of our approach, for the SISO case, an essentially orthogonal structure is obtained for the inverse filter; only one of the Givens roto...
