Our time in La Paz was to be split between sessions with the whale sharks and sessions freediving on a line working on technique with our young ambassadors and instructors before heading out to sea with the Nautilus Explorer to tag scalloped hammerhead sharks in the Revillagigedo Archipelago. ...
free carriers in the plasma rapidly increases in multiphoton ionization and avalanche ionization. The laser energy is primordially absorbed by free electrons, resulting in the remarkable increase of the kinetic energy of the free electrons. Meanwhile, part ...
Once the image is noise-free, the patterns are extracted from it with the help of the likelihood gradient pattern technique. Subsequently, the label formation and blob extraction processes are performed in an orderly manner to track the target object accurately. In this work, the novelty is ...
Kind Code: C1 Abstract: The underwater mine (13) is detected by the mine sweeper or by an underwater drogue towed behind the mine sweeper. High velocity projectiles (16) are fired at the mine from the surface vessel, or from the drogue, or from a remote controlled launcher (22) set ...

Kind Code: A1 Abstract: An underwater transformer (1,1A) has an electrical transformer (2) in a transformer tank (3) with electrical terminals (4,5,6), and an outer tank (7) filled with a liquid coolant (8) encloses the transformer tank (3). The outer tank (7) is partially fille...
The methods mainly include (1) hard sampling methods, such as random sampling and online hard example mining [7]; (2) soft sampling methods, such as focal loss [6] and gradient harmonizing mechanism [17]; (3) sampling-free methods, such as AP-loss [18]; (4) generative methods, such...
