Ducted Propellers: Behaviour in Waves and Scale Effects
Bhattacharyya, Anirban (Doctoral thesis at NTNU;2015:299, Doctoral thesis, 2015)Ducted propellers find their application in a wide range of marine vessels, such as cargo ships, tugboats, submarines, trawlers etc. Preference over the open propeller depends on a variety of factors, the most common ... -
Predicting vessel speed in the Arctic without knowing ice conditions using AIS data and decision trees
Rao, Prithvi S.; Kim, Ekaterina; Smestad, Bjørnar Brende; Asbjørnslett, Bjørn Egil; Bhattacharyya, Anirban (Peer reviewed; Journal article, 2021)The vessel speed is one of the important parameters that govern safety, emergency, and transport planning in the Arctic. While previous studies have traditionally relied on physics-based simulations to predict vessel's ... -
Supplementing remote sensing of ice: Deep learning-based image segmentation system for automatic detection and localization of sea ice formations from close-range optical images
Panchi, Nabil; Kim, Ekaterina; Bhattacharyya, Anirban (Peer reviewed; Journal article, 2021)This paper presents a three-stage approach for the automated analysis of close-range optical images containing ice objects. The proposed system is based on an ensemble of deep learning models and conditional random field ... -
The influence of using a ducted propeller on motions and speed loss of a ship in waves
Pan, Qi (Master thesis, 2013)Comparisons of experimental and numerical investigations into the effect of duct on motion variables and speed loss for a given ship model are presented. The purpose of these comparisons is to verify the advantage of using ... -
Understanding Polar Environment: Preliminary Results from Deep-Learning-based Segmentation of Optical Ice Images
Panchi, Nabil; Kim, Ekaterina; Bhattacharyya, Anirban (Chapter, 2019)Computer vision-aided scene understanding has drawn much attention, especially in autonomous vehicles and advanced driver assistance systems. Image segmentation forms the core of these systems, which is required for effective ...
