Analyzing the Influence of Water Depth on Total Resistance in Ulstein X-Bow Configuration: A Numerical Study [PDF]

E3S Web of Conferences, 2023
Considering resistance is a vital factor during ship design, especially when the vessel navigates through shallow waters. This situation leads to increased hull pressure as the ship advances.

Convolutional Neural Networks and Transfer Learning Based Classification of Natural Landscape Images [PDF]

Journal of Universal Computer Science, 2020
Natural landscape image classification is a difficult problem in computer vision. Many classes that can be found in such images are often ambiguous and can easily be confused with each other (e.g. smoke and fog), and not just by a computer algorithm, but
