Investigation of Fault-Tolerant Capabilities in an Advanced Three-Level Active T-Type Converter [PDF]

, 2019
A novel fault-tolerant three-level power converter topology, named advanced three-level active T-Type (A3L-ATT) converter, is introduced to increase the reliability of multilevel power converters used in safety-critical applications.

MXene‐Based Flexible Memory and Neuromorphic Devices

Small, EarlyView.
The unique two‐dimensional structure, excellent electrical conductivity, and diverse surface groups of MXenes have garnered significant attention. Coupled with their exceptional flexibility, MXene‐based devices hold immense potential for flexible memory and neuromorphic systems. This review comprehensively discusses the fundamentals of flexible devices,

A Seven-level defined selective harmonic elimination PWM strategy [PDF]

, 2006
Selective harmonic elimination pulse-width modulation (SHE-PWM) techniques offer an optimized control approach for a given converter and are therefore suitable for the low switching frequency high-power applications.

Fluorescent Supramolecular Gels Based on D‐Sorbitol Derivatives

Small, EarlyView.
Sugar‐based fluorescent low‐molecular‐weight gelators (LMWGs) DNapS, DBTDS, and MCumS, prepared by a green, scalable route, form supramolecular gels in water, organic, and deep eutectic solvents. MCumS yields solvent‐dependent nanofibrous networks and viscoelastic injectable eutectogels.

New Hybrid Cascaded Multilevel Inverter

International Journal of Engineering, 2013
A B S T R A C T This paper proposes a single-phase five-level inverter with a modified pulse width- modulated (PWM) control scheme. The modified pulse width-modulation technique is developed to reduce switching losses. Also, the proposed multilevel inverter can reduce the requirement of power switches compared to a conventional cascaded multilevel ...

Synergistic Pyroelectric‐Bolometric Coupling in Tellurene Nanowire for Energy‐Efficient Artificial Vision

Small, EarlyView.
Synergistic pyroelectric–bolometric coupling in Tellurene nanowires enables efficient photothermal conversion and self‐driven synaptic functionality. Edge‐induced polarization and temperature‐dependent resistance cooperatively generate enhanced transient responses and multilevel conductance states.

Modelling Suicide‐Related Communication Dynamics: A Socio‐Cybernetic Framework for Governance

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Suicide‐related phenomena (SPS) are often approached through individual‐level risk factors or moral framings, yet their population‐level dynamics depend critically on how ‘suicide’ becomes observable, circulates and is governed across functionally differentiated systems.

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

Structural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

A tutorial for understanding SEM using R: Where do all the numbers come from?

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Structural equation modeling (SEM) is often seen as a complex and difficult method, especially for those who want to understand how the numbers in SEM software output are actually computed. Although many open‐source SEM tools are now available—especially in the R programming environment—looking into their source code to understand the ...

Ripple Effects: Social Turmoil Following Infant Kidnapping Attempts in Wild Geladas

Ethology, EarlyView.
Graphical abstract illustrating the social consequences of infant kidnapping in wild geladas (Theropithecus gelada). The study monitors a 28‐day period divided into a 14‐day pre‐kidnapping phase and a 14‐day post‐kidnapping phase. ABSTRACT Infant kidnapping is an extreme social disruption reported in some primate species, yet its consequences on social
