An Automatic Identification System (AIS) Database for Maritime Trajectory Prediction and Data Mining [PDF]

open access: yes, 2017
In recent years, maritime safety and efficiency become more and more important across the world. Automatic Identification System (AIS) tracks vessel movement by onboard transceiver and terrestrial and/or satellite base station. The data collected by AIS contains broadcast kinematic information and static information. Both of them are useful for anomaly

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

open access: yessteel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

GenAI‐Assisted Digital Multimodal Composing in TESOL Teacher Education

open access: yesTESOL Quarterly, EarlyView.
Abstract This study explored how pre‐service TESOL teachers integrated GenAI tools into a Digital Multimodal Composing (DMC) project, composing a website, at a Hong Kong university. Specifically, it explored their decision‐making and cognitive engagement in the DMC process when they had autonomy in the use of GenAI tools.

Distributed acoustic sensing for marine mammal monitoring

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Marine mammal monitoring provides critical data to inform species management and sustainable industrial development. Passive acoustic monitoring, in particular, can provide continuous, long‐term and non‐observer‐biased data, with a subset of systems capable of delivering data in near‐real time.
