Ve-Degree, Ev-Degree, and Degree-Based Topological Indices of Fenofibrate

open access: yesJournal of Mathematics, 2022
The molecular topology of a graph is described by topological indices, which are numerical measures. In theoretical chemistry, topological indices are numerical quantities that are used to represent the molecular topology of networks.

A new quasi‐Z‐source switched‐boost four‐switch three‐phase inverter with independent shoot‐through and non‐shoot‐through modulation indexes

open access: yesIET Power Electronics, 2021
Four‐switch three‐phase inverters (FSTPI) are the cost‐optimised version of two‐level voltage source inverters (TL‐VSI), promoted for low‐power/low‐voltage machine drive systems.

A 7L and 11L High Step-Up SCMLI Topology With Reduced Component Voltage Stress

open access: yesIEEE Access, 2023
This article proposes a new capacitor-based multilevel inverter topology (CBMLI) with fewer devices and reduced voltage stress on capacitors and switches. In addition, the proposed topology can be configured as either a 7-level (7L) or 11L circuit with a

Real-Time Computing of Touch Topology via Poincare–Hopf Index

open access: yesIEEE Access, 2015
While visual or tactile image data have been conventionally processed via filters or perceptron-like learning machines, the recent advances of computational topology may make it possible to successfully extract the global features from the local ...

Eigenvalue knots and their isotopic equivalence in three-state non-Hermitian systems

open access: yesPhysical Review Research, 2023
The spectrum of a non-Hermitian system generically forms a two-dimensional complex Riemannian manifold with a distinct topology from the underlying parameter space. This spectral topology permits eigenvalue trajectories to braid into knots. In this paper,

A new topology of the switched-inductor/capacitor quasi Z-source inverter with ability of uplifted-boost [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization, 2020
In this paper, a new topology of switched-inductor/capacitor quasi impedance source inverter is suggested, which in comparison with the other topologies possesses higher boost voltage inversion at high modulation index and low shoot through duty cycle ...

Single-phase transformerless nine-level inverter with voltage boosting ability for PV fed AC microgrid applications

open access: yesScientific Reports, 2022
This letter presents a new single-stage common ground type nine-level (9L) switched-capacitor inverter topology with single-phase operation. The primary objective of this topology is to reduce the leakage current, voltage boosting, and maintain the ...

Linear versus nonlinear reliability-based topology optimization with application to bridge structures [PDF]

open access: yesE3S Web of Conferences, 2021
In general, two types of topology optimization models can be found in literature. The first type is called Deterministic Topology Optimization (DTO) leading to a single layout when considering a given design space.
