From captain to button-presser: operators’ perspectives on navigating highly automated ferries
Autor: Erik Veitch, Kim Alexander Christensen, Markus Log, Erik Thule Valestrand, Sigurd Hilmo Lundheim, Martin Nesse, Ole Andreas Alsos, Martin Steinert
Publikováno v: Journal of Physics: Conference Series (JPCS)
Teaming with Artificial Intelligence (AI) is changing the way seafarers work. We show that a new kind of seafaring is emerging, characterized by cooperation with AI systems. In this format of seafaring, navigation tasks are controlled automatically w

Vision-based positioning of Unmanned Surface Vehicles using Fiducial Markers for automatic docking
Autor: Lars Digerud, Øystein Volden, Kim A. Christensen, Sampsa Kohtala, Martin Steinert
Publikováno v: IFAC-Papers
This paper describes a method of using fiducial markers to aid Unmanned Surface Vehicles (USVs) as an additional positioning source during auto-docking. Vision-based techniques allow USVs to localize themselves relative to their surroundings without

Abdim's Stork Ciconia abdimii in Niger: population size, breeding ecology and home range
Autor: Knud Falk, Bo Svenning Petersen, Flemming Pagh Jensen, Kim Diget Christensen
Publikováno v: Ostrich. 79:177-185
Abdim's Stork is a common breeding bird in most human settlements across the Sahel. However, very few studies have surveyed the population and described its breeding and feeding ecology during the breeding season. We identified the breeding range in

Abdim’s Stork Ciconia abdimii Exploitation of Senegalese Grasshopper Oedaleus senegalensis in South-eastern Niger
Autor: Zakaria Ouambama, Flemming Pagh Jensen, Kim Diget Christensen, Bo Svenning Petersen, Knud Falk
Publikováno v: Waterbirds. 31:159-168
Abdim’s Storks Ciconia abdimii were studied in a post-breeding staging area dominated by Sahelian grasslands in southeastern Niger. In late September 2003, a total of 5,763 birds was recorded on systematic transect counts. The estimated density was
