Power Quality Improvement with a Pulse Width Modulation Control Method in Modular Multilevel Converters under Varying Nonlinear Loads

Applied Sciences, 2020
In order to reach better results for pulse width modulation (PWM)-based methods, the reference waveforms known as control laws have to be achieved with good accuracy. In this paper, three control laws are created by considering the harmonic components of

A construction of relatively pure submodules

, 2012
We reconsider a classical theorem by Bican and El Bashir, which guarantees the existence of non-trivial relatively pure submodules in a module category over a ring with unit.

Zariski Topologies for Coprime and Second Submodules [PDF]

Algebra Colloquium, 2015
Let M be a non-zero module over an associative (not necessarily commutative) ring. In this paper, we investigate the so-called second and coprime submodules of M. Moreover, we topologize the spectrum Spec s (M) of second submodules of M and the spectrum Spec c (M) of coprime submodules of M, study several properties of these spaces and investigate ...

Support theory via actions of tensor triangulated categories

, 2012
We give a definition of the action of a tensor triangulated category T on a triangulated category K. In the case that T is rigidly-compactly generated and K is compactly generated we show this gives rise to a notion of supports which categorifies work of

Coordinated Control of Second-Order Harmonic Voltage and Current Fluctuations in Cascaded H-Bridge Inverter with Supercapacitor and DC-DC Stage at Variable Output Frequencies

CES Transactions on Electrical Machines and Systems
In the cascaded H-bridge inverter (CHBI) with supercapacitor and dc-dc stage, inherent second-order harmonic power flows through each submodule (SM), causing fluctuations in both the dc-link voltage and the dc-dc current.

Lagrangian mapping class groups from a group homological point of view

, 2011
We focus on two kinds of infinite index subgroups of the mapping class group of a surface associated with a Lagrangian submodule of the first homology of a surface.

Multimodal Wearable Biosensing Meets Multidomain AI: A Pathway to Decentralized Healthcare

Advanced Science, EarlyView.
Multimodal biosensing meets multidomain AI. Wearable biosensors capture complementary biochemical and physiological signals, while cross‐device, population‐aware learning aligns noisy, heterogeneous streams. This Review distills key sensing modalities, fusion and calibration strategies, and privacy‐preserving deployment pathways that transform ...
