Convex Flexible Branch Model (CFBM): Convex model for solving AC/DC hybrid networks optimal power flows

International Journal of Electrical Power & Energy Systems
Transmission technologies such as VSC-High-Voltage DC (HVDC) transmission and Multi Terminal DC (MTDC) grids are becoming more common due to their advantages for bulk transmission and their ability to provide coupling conditions for RES-based generation.

The effect of the incidence function on the existence of backward bifurcation

Letters in Biomathematics, 2016
In modelling, the dynamics of infectious disease, the choice of the specific mathematical formulation of disease transmission (i.e. the incidence function) is one of the initial assumptions to be made.

Irreversible Quantum Mechanics in the Neutral K-System [PDF]

, 1997
The neutral Kaon system is used to test the quantum theory of resonance scattering and decay phenomena. The two dimensional Lee-Oehme-Yang theory with complex Hamiltonian is obtained by truncating the complex basis vector expansion of the exact theory in

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

FEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

Application of explicit model predictive control to a vehicle semi-active suspension system

Journal of Low Frequency Noise, Vibration and Active Control, 2020
The vehicle semi-active suspension is a typical multiple-input multiple-output system with strong couplings, actuator constraints and fast dynamics. This paper addresses the damping force regulation of shock-absorber in vehicle semi-active suspensions ...

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Harris Hawks Optimization for Optimum Design of Truss Structures with Discrete Variables [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2021
This article investigates the use of Harris Hawks Optimization (HHO) to solve planar and spatial trusses with design variables that are discrete. The original HHO has been used to solve continuous design variables problems.
