Experimental and Numerical Investigation of the Added Resistance in Regular Head Waves for the DTC Hull

open access: yesJournal of Marine Science and Engineering, 2023
Reducing the added resistance in waves has become a crucial aspect of today’s ship design. The added resistance in waves is traditionally considered proportional to the square of wave height.

Method for rudder roll stabilization control by maintaining ship speed

open access: yesZhongguo Jianchuan Yanjiu, 2017
A ship navigating on the surface of the water may experience greater resistance, adversely affect-ing its speed and leading to energy loss. The added resistance of surface ships in both still water and waves are investigated, and the computation method ...

Resistivity of polonium (Ad Interim) [PDF]

open access: yes, 1949
Apparatus for measuring the resistivity of polonium is described. This equipment has been built and tested. No resistivity measurements were made, however, because the method of determining the purity of the sample has not been perfected.

Efficient quantum key distribution secure against no-signalling eavesdroppers [PDF]

open access: yes, 2006
By carrying out measurements on entangled states, two parties can generate a secret key which is secure not only against an eavesdropper bound by the laws of quantum mechanics, but also against a hypothetical "post-quantum" eavesdroppers limited by the ...

Adding Resistances and Capacitances in Introductory Electricity [PDF]

open access: yesThe Physics Teacher, 2005
All introductory physics textbooks, with or without calculus, cover the addition of both resistances and capacitances in series and in parallel as discrete summations. However, none includes problems that involve continuous versions of resistors in parallel or capacitors in series. This paper introduces a method for solving the continuous problems that

ADDED RESISTANCE OF SHIPS IN QUARTERING SEAS

open access: yes, 2013
In this paper, the 3D panel method of NTUA-SDL for calculating the added resistance of a ship in bow seas has been extended and validated for the quartering seas case. At first we studied the drift force on a semi-submersible in quartering seas.

Swimming Speeds of Waving Cylindrical Tails in Viscous Fluids with Resistance

open access: yes, 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 ...
