The Negative Poisson’s Ratio Ship Base Design and Vibration Isolation Performance Analysis

open access: yesApplied Sciences, 2021
This paper mainly studies the vibration isolation of negative Poisson’s ratio structure in the honeycomb base of ships. Based on the structure of the negative Poisson’s ratio structure, different laying methods and different cell structure are used to ...

On the inclined static loading of honeycomb re-entrant auxetics

open access: yes, 2021
The present study unravels the deformation mechanisms observed during the static inclined compression of re-entrant honeycomb (RH) auxetic structure. A pushover Riks analysis is conducted by facing a rigid plate towards the structure at various angles. A

Severe Heart Failure Associated With Tachycardia-Induced Cardiomyopathy Due to Incessant Atrioventricular Re-Entrant Tachycardia

open access: yesJACC: Case Reports, 2021
Short RP interval atrioventricular re-entrant tachycardias do not typically present as an incessant form. We present 2 cases of incessant atrioventricular re-entrant tachycardias leading to tachycardia-induced cardiomyopathy with severe heart failure ...

Modeling and Analysis of Material Flows in Re-Entrant Supply Chain Networks Using Modified Partial Differential Equations

open access: yesJournal of Applied Mathematics, 2011
The basic partial differential equation (PDE) models for supply chain networks with re-entrant nodes and their macroscopic are proposed. However, through numerical examples, the basic continuum models do not perform well for multiple re-entrant systems ...

Dynamics of cavity structures and wall-pressure fluctuations associated with shedding mechanism in unsteady sheet/cloud cavitating flows

open access: yesFlow, 2023
The physics and mechanism of sheet/cloud cavitation in a convergent–divergent channel are investigated using synchronized dynamic surface pressure measurement and high-speed imaging in a water tunnel to probe the cavity shedding mechanism.

Investigation of Water Injection Influence on Cloud Cavitating Vortical Flow for a NACA66 (MOD) Hydrofoil

open access: yesEnergies, 2021
Re-entrant jet causes cloud cavitation shedding, and cavitating vortical flow results in flow field instability. In the present work, a method of water injection is proposed to hinder re-entrant jet and suppress vortex in cloud cavitating flow of a ...

Modeling re-entrant manufacturing systems with inspections [PDF]

open access: yesProceedings of 1995 IEEE International Conference on Robotics and Automation, 2002
Inspection stations are now an integral part of any manufacturing system and help track product quality and process performance. In this paper the authors consider re-entrant manufacturing systems (such as semiconductor fabrication facilities) with inspections at various stages of processing.

Heuristic based genetic algorithms for the re-entrant total completion time flowshop scheduling with learning consideration

open access: yesInternational Journal of Computational Intelligence Systems, 2016
Recently, both the learning effect scheduling and re-entrant scheduling have received more attention separately in research community. However, the learning effect concept has not been introduced into re-entrant scheduling in the environment setting.

Microwave bandpass filters using re-entrant resonators. [PDF]

open access: yes, 2015
Design techniques for microwave bandpass filters using re-entrant resonators are presented. The key feature is that each re-entrant resonator in the filter generates a passband resonance and a finite frequency transmission zero, above the passband.
