Container Port Efficiency and Productivity in 2019 and 2020: A Directional Distance Function Incorporating Vessel Waiting Time

This study examines change in operational efficiency and productivity across a balanced panel of 15 container ports for the years 2019 and 2020. Berth length, gantry cranes, and other cranes are inputs; high container throughput is desirable, and extended anchorage waiting time i...

A New Branchipolynoe (Aphroditiformia: Polynoidae) Scale Worm from the Onnuri Deep-sea Hydrothermal Vent Field, Northern Central Indian Ridge

. Phylogenetic analyses support close relationships between the Indian Ocean and Western Pacific hydrothermal polychaetes. Our data provide a foundation for exploring the evolutionary relationship between scale worms and bathymodiolin mussels.

A Lyapunov-Gated Adaptive Law for Drift-Free Neural-Network Depth Control of a Remotely Operated Vehicle in Persistent Seas

This paper addresses the depth regulation of an inspection-class remotely operated vehicle whose hydrodynamic model is uncertain and whose environment applies a persistent, non-vanishing wave disturbance. A neural-network learning term added to a proportional-derivative feedback...
