Calculation and analysis of torsional vibration of electrical propulsion system under a short-circuit-induced impulse load

open access: yesZhongguo Jianchuan Yanjiu, 2020
Objectives For an electrical propulsion system, the transient torque induced by short-circuit faults is so large that it will exert a greater impact on the safety of shipboard electric propulsion system.

Analysis of sensor impulse response effects on Cramèr–Rao lower bounds for signal parameter estimators

open access: yesThe Journal of Engineering, 2014
In this study, a generic analysis of sensor impulse response effects on linearly filtered channel noise is presented to illustrate the resulting variations to the Cramèr–Rao lower bounds (CRLBs) of signal parameter estimators in signal processing and ...

Closed-form critical earthquake response of elastic-plastic structures on compliant ground under near-fault ground motions

open access: yesFrontiers in Built Environment, 2016
The double impulse is introduced as a substitute of the fling-step near-fault ground motion. A closed-form solution of the elastic-plastic response of a structure on compliant (flexible) ground by the ‘critical double impulse’ is derived for the first ...

Saturated impulse and application of saturation equivalent method in cabin explosion

open access: yesZhongguo Jianchuan Yanjiu, 2021
ObjectivesFor the ship structures subjected to pulse loading such as explosion or slamming, research on the "saturated impulse" phenomenon shows that designing hull structures with maximum loading amplitude and total impulse is unreasonable.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Critical response of a single-degree-of-freedom system with bilinear hysteresis and viscous damping under triple impulse

open access: yesFrontiers in Built Environment
A triple impulse is used as a mathematical model of forward-directivity inputs, which are fault-normal components of near-fault earthquake ground motions. In this paper, two types of the triple impulse input are employed.

Critical earthquake response of a SDOF elastic‐perfectly plastic model with viscous damping under double impulse as a substitute for near‐fault ground motion

open access: yesJapan Architectural Review, 2018
The double‐impulse input is introduced as a substitute for the fling‐step near‐fault ground motion, and a closed‐form solution for the approximate elastic‐plastic response of a structure with viscous damping under the “critical double impulse” is derived.
