Theoretical Analysis of Active–Reactive Power Decoupling Control for DSSC Based on Magnetically Coupled Reactors

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Distributed Static Synchronous Compensator (DSSC) is essential for flexible power flow control in renewable energy integrated systems but suffers from severe active–reactive power coupling that deteriorates voltage quality and dynamic performance. This paper proposes a hardware‐assisted decoupling method using magnetically coupled reactors (MCRs) to ...

Research on Aerodynamic Damping of Bladed Disk With Random Mistuning

, 2017
This paper presents an investigation on the aerodynamic damping of bladed disk (also called ‘blisk’) with mistuning. The study focuses mainly on the mechanism of the effect of random and intentional mistuning on the aero-elastic stability of blisk.

Control Algorithm for Distributed Multiple Semiactive Tuned Mass Dampers in Base‐Isolated Buildings Under Earthquake Excitations

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
This study presents a generalized mathematical formulation and performance evaluation of an energy‐based predictive (EBP) control algorithm for mitigating the seismic response of base‐isolated (BI) multistory buildings equipped with distributed multiple semiactive tuned mass dampers (DM‐SATMDs). Although base isolation effectively limits superstructure

Nonlinear Vibrations and Control of Wind Towers With Variable Cross Section and Elastic Foundation

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
This study proposes a comprehensive nonlinear modeling and vibration control framework for wind towers subjected to the simultaneous and often conflicting demands of aerodynamic and seismic excitations. The primary contribution of this work involves the development of a fully geometrically nonlinear, high‐fidelity coupled tower–nacelle–blade model that

Reduced-Order Models of Blisks With Small Geometric Mistuning

, 2017
A technique for generating reduced-order models (ROMs) of bladed disks with small geometric mistuning is proposed. Discrepancies in structural properties (mistuning) from blade to blade can cause a significant increase in the maximum vibratory stress ...

Inter‐Stimulus‐Interval Dependence in Auditory Cortex Reflects Perceptual Organization of Streams Under Informational Masking

Psychophysiology, Volume 62, Issue 12, December 2025.
ABSTRACT The perceptual saliency of a regular sound sequence embedded into a well‐chosen multi‐tone‐masker background fluctuates despite the absence of change in the physical stimulus. When such tone streams are perceived, each tone of the stream evokes a negative‐going response referred to as awareness‐related negativity (ARN).

Real‐time electron spectrometer utilizing a permanent magnet and diode detector array

Medical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Magnetic spectrometers have been previously described for measuring energy spectra of therapeutic electron beams. However, challenges for clinical utilization have been their size, weight, and limited real‐time capabilities. Development of a compact, lightweight, and inexpensive device with real‐time readout will make an electron ...
