Automatic Determination of Quasicrystalline Patterns from Microscopy Images

Advanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

Simulation of ship motions coupled with tank sloshing in frequency domain

Zhongguo Jianchuan Yanjiu, 2019
[Objectives] With the increase in the size of the ship with liquid tanks (LNG, FPSO, FLNG, etc.) and the improvement of work efficiency and operational safety, the coupled problem between the tank sloshing and the resulting ship motions have become more ...

Hydrodinamic Aspects of a High-Speed SWATH and New Hull Form [PDF]

, 2005
The main problems of high-speed ships operating in open seas are their insufficient seaworthiness and speed loss in high sea states. Small Water-plane Area Twin-Hulls (SWATH) are characterised by excellent seaworthiness, but the hull forms of a ...

Remora‐Inspired Sensing Suction Cup with Adhesion Monitoring and Force Detection

Advanced Intelligent Systems, EarlyView.
A suction cup with integrated liquid metal microchannel sensors enables stable multidirectional force sensing and adhesion monitoring in both air and water. The flexible resistive sensors, placed on the outer lip, transduce deformations into resistance changes under normal and shear loads.

Sonar micro-Doppler effect induced by ship oscillatory motion in waves: Phenomenon, model, and experimentation [PDF]

JASA Express Letters
Traditional research attributes the modulated sidebands of ship radiation line-spectrum signals to reflections off rough ocean surfaces, but the Doppler effect caused by vessel motion may also contribute.

CFD simulations of vertical ship motions in shallow water [PDF]

, 2016
The seakeeping behaviour of a vessel in shallow water differs significantly from its behaviour in deep water. In shallow water, a vessel’s motion responses to incident waves will be affected by hydrodynamic effects caused by the presence of a finite ...

Examining pathways by which socioeconomic instability in adolescence influence sexual health during emerging adulthood in an agricultural setting in California

American Journal of Community Psychology, EarlyView.
Abstract This study investigates the longitudinal impact of socioeconomic instability on teen pregnancy and sexually transmitted infection (STI) diagnosis among adolescents and young adults (AYA) living in an agricultural region and examines pathways including supportive family and social structures, decision making autonomy in romantic relationships ...
