Swimming Speeds of Waving Cylindrical Tails in Viscous Fluids with Resistance
, 2015 Many microorganisms swim in a highly heterogeneous environment with obstacles such as fibers or polymers. To better understand how this environment affects microorganism swimming, we study propulsion of a cylinder or filament in a fluid with a sparse ...

Application of the Design of Experiments and Computational Fluid Dynamics to Bow Design Improvement
Journal of Marine Science and Engineering, 2019 Techniques of the design of experiments (DOE) and computational fluid dynamics (CFD) were applied for improving the bow shape of a tanker hull. Through this, a hull that could reduce the added resistance in waves was derived.

Calculation of Added Resistance in Oblique Waves
Journal of the Society of Naval Architects of Japan, 1980 The formula for the added resistance of a ship in oblique waves is simplified by the assumption of high frequency of encounter. Numerical computations by the simplified formula are carried out with respect to the Series 60, CB=0.70 model at various heading angles to the wave.

The Quantized Hall Insulator: A New Insulator in Two-Dimensions
, 1998 Quite generally, an insulator is theoretically defined by a vanishing conductivity tensor at the absolute zero of temperature. In classical insulators, such as band insulators, vanishing conductivities lead to diverging resistivities. In other insulators,

Evaluation of the Effect of Container Ship Characteristics on Added Resistance in Waves
Journal of Marine Science and Engineering, 2020 Added resistance in waves is one of the main causes of an increase in required power when a ship operates in actual service conditions. The assessment of added resistance in waves is important from both an economic and environmental point of view, owing ...
