Power quality improvement of grid‐connected solar power plant systems using a novel fractional order proportional integral derivative controller technique

open access: yesIET Renewable Power Generation, Volume 18, Issue 15, Page 3268-3284, 16 November 2024.
Integrate renewable energy system (RES) into grid‐connected load system in enhancing reliability and reducing losses. However, integrating these systems introduce power quality (PQ) issues, especially with non‐linear, critical, and imbalanced loads. Addressing this, a hybrid mantis search‐reptile search algorithm combined with a unified power quality ...

Unsteady dean flow of dusty fluids between two oscillating cylinders

open access: yesProceedings of the Nigerian Society of Physical Sciences
This study investigates the unsteady Dean flow of dusty, viscous, incompressible fluids confined between two oscillating concentric horizontal cylinders under a semi-analytical framework based on Laplace transformation, which is preferred over fully ...

Random Sequential Addition of Hard Spheres in High Euclidean Dimensions

open access: yes, 2006
Employing numerical and theoretical methods, we investigate the structural characteristics of random sequential addition (RSA) of congruent spheres in $d$-dimensional Euclidean space $\mathbb{R}^d$ in the infinite-time or saturation limit for the first ...

Near Optimal Adjacency Labeling Schemes for Power-Law Graphs [PDF]

open access: yes, 2016
An adjacency labeling scheme labels the n nodes of a graph with bit strings in a way that allows, given the labels of two nodes, to determine adjacency based only on those bit strings.

Do All Elliptic Curves of the Same Order Have the Same Difficulty of Discrete Log?

open access: yes, 2005
The aim of this paper is to justify the common cryptographic practice of selecting elliptic curves using their order as the primary criterion. We can formalize this issue by asking whether the discrete log problem (DLOG) has the same difficulty for all ...

Compact binary evolutions with the Z4c formulation [PDF]

open access: yes, 2012
Numerical relativity simulations of compact binaries with the Z4c and BSSNOK formulations are compared. The Z4c formulation is advantageous in every case considered.

Seagrass recovery trajectories and recovery potential in relation to nutrient reduction

open access: yesJournal of Applied Ecology, Volume 61, Issue 8, Page 1784-1804, August 2024.
Within a large seascape (15,000 km2) the least eutrophicated region showed seagrass recovery upon nutrient reduction. We translated the critical riverine nutrient loads for this recovery, via regional eutrophication indicators, to loads that may enable a sustained recovery in the other regions.

Reformulation of the Covering and Quantizer Problems as Ground States of Interacting Particles

open access: yes, 2010
We reformulate the covering and quantizer problems as the determination of the ground states of interacting particles in $\mathbb{R}^d$ that generally involve single-body, two-body, three-body, and higher-body interactions.

Conformally invariant scaling limits in planar critical percolation

open access: yes, 2011
This is an introductory account of the emergence of conformal invariance in the scaling limit of planar critical percolation. We give an exposition of Smirnov's theorem (2001) on the conformal invariance of crossing probabilities in site percolation on ...
