Steady-State Analysis of Load Balancing with Coxian-$2$ Distributed Service Times

, 2021
This paper studies load balancing for many-server ($N$ servers) systems. Each server has a buffer of size $b-1,$ and can have at most one job in service and $b-1$ jobs in the buffer. The service time of a job follows the Coxian-2 distribution.

Nature‐Inspired Janus Actuators with Structurally Engineered PEDOT:PSS

Small, Volume 22, Issue 2, 8 January 2026.
Nature‐inspired PEDOT:PSS Janus actuators are fabricated through a dual solvent‐acid treatment that induces asymmetric conductivity and hydrophobicity within a unified structure. The actuator demonstrates large, reversible bending (3 cm−1) under low voltage (4 V), heat, and vapor stimuli, with minimal Joule heating and excellent cyclic durability ...

Radial basis functions-finite differences collocation and a Unified Formulation for bending, vibration and buckling analysis of laminated plates, according to Murakami's zig-zag theory [PDF]

, 2011
In this paper, we propose to use the Murakami's zig-zag theory for the static and vibration analysis of laminated plates, by local collocation with radial basis functions in a finite differences framework.

Impact of SSSC-ES on Bifurcations of SSR

Energy Procedia, 2017
Abstract FACTS controllers incorporating energy storage device has the ability to operate in all the four quadrants and thereby increases the operational flexibility. In this work, the influence of SSSC supported by Energy Storage (SSSC-ES) on subsynchronous resonance (SSR), in a system provided with fixed series compensation is studied.

A Spectroscopic Investigation of Halogen Bonding for the Adsorption Process of Grafted Chitosan With Fluorescein Versus Rose Bengal Dye Systems

ChemistrySelect, Volume 10, Issue 47, December 15, 2025.
Chitosan was modified by grafting of aniline via cross‐linking with urea and characterized by complementary methods. Adsorption studies of chitosan and its grafted form were carried out in single‐component solutions of fluorescein (FL) and rose bengal (RB), along with their binary (FL+RB) mixtures.

Small signal stability constrained optimal power flow model based on trajectory optimization

Energy Reports, 2023
The essence of traditional power system’s small signal stability analysis model using the eigenvalue analysis method is to analyze the time-invariant system obtained after the approximate linearization of the system, because it only considers the ...
