Cognitive competency is an essential complement to the existing ship pilot screening system that should be focused on. Situation awareness (SA), as cognitive foundation of unsafe behaviors, susceptible influencing piloting performance. To address this issue, paper develops identification model based on random forest- convolutional neural network (RF-CNN) method for detecting at-risk (i.e., low SA level) using wearable EEG signal acquisition technology. In poor visibility scene, pilots'...

To maintain situation awareness (SA) when exposed to emergencies during pilotage, a pilot needs selectively allocate attentional resources perceive critical status information about ships and environments. Although it is important continuously monitor pilot’s SA, its relationship with attention still not fully understood in ship pilotage. This study performs bridge simulation experiments that include vessel departure, navigation the fairway, encounters, poor visibility, anchoring scenes 13...

Visual characteristics have the potential to assess navigational proficiency of ship pilots. A precise assessment piloting competence is imperative mitigate human errors in piloting. An exhaustive examination cognitive capabilities plays a pivotal role developing an enhanced and refined system for classifying, selecting, training proficiency. Insufficiency situation awareness (SA), denoting underpinning hazardous behaviors among pilots, may lead subpar performance pilotage when faced with...

Situation awareness (SA) of pilots’ unsafe behavior can ensure safety onboard. Thus, the cognitive mechanism that controls SA leading to must be articulated. This study employs model and theory planned (TPB) articulate a quantitative ship safe piloting. Firstly, hierarchical classification framework behaviors was constructed as an analytical foundation for rational unconscious in sight processes, then measurement elements mechanisms were identified. Subsequently, based on structural model,...

With the rapid development of economy, our country's marine transportation passageways get more crowded.Especially in region Taiwan Strait, crude oil import East Asian districts as well between lines North and South makes traffic busier than ever before.Besides, since permission vessels correspondence China accompanied by greatly increasing encounter probability vessels, navigation safety Strait appears extremely essential.This article aims to provide security guidance covering risk aversion...

Abstract In order to improve the symmetry of flutter mechanism in bionic aircraft, and then overall motion stability aircraft. this paper, an innovative wing configuration is designed based on a planar crank-slider sparrow model. The geometric relationship established, aircraft modeled, dimensions model are optimized. structure was simulated analyzed by CATIA. results show that upper limit angle βmax=25.82° lower βmin=6.34°. CATIA simulation data consistent with theoretical values...

Electroencephalography (EEG) has the potential to identify at-risk cognitive states in ship pilots. Situation awareness (SA) deficiency is foundation of unsafe behavior by pilots, and this can easily lead negative performance pilotage under crossover encounter conditions. To address issue, paper describes an identification framework for detecting state (i.e., low SA levels) pilots using wearable EEG signal acquisition technology. A total fourteen correlation features θ/β、α/β、θ/(α+θ), (α+θ)/β...
