Phenomenological rate-independent uniaxial hysteretic models: A mini-review

open access: yesFrontiers in Built Environment, 2022
A great variety of phenomenological models has been proposed over the years to model rate-independent hysteretic forces in structural mechanics. The classification of such models is usually based on the type of equation that needs to be solved to ...

Harmonic elimination of a fifteen‐level inverter with reduced number of switches using genetic algorithm

open access: yesIET Power Electronics, EarlyView., 2023
This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated

Differential transcendence criteria for second-order linear difference equations and elliptic hypergeometric functions [PDF]

open access: yes, 2019
We develop general criteria that ensure that any non-zero solution of a given second-order difference equation is differentially transcendental, which apply uniformly in particular cases of interest, such as shift difference equations, q-dilation ...
