Application of fin system to reduce pitch motion

International Journal of Naval Architecture and Ocean Engineering, 2016
Container ships are prone to move at a greater speed compared to other merchant ships. The slenderness of the hull of container vessel is for better speed, but it leads to unfavorable motions. The pitch and roll are related and sometimes the vessel might

Calculation and Analysis of Rolling Hydrodynamic Coefficients of Free-Flooding Ship Based on CFD

Journal of Marine Science and Engineering
As free-flooding ships are a type of vessel with openings on their hull surfaces, accurately calculating and analyzing their roll hydrodynamic coefficients is of great significance for ship motion prediction.

Lateral Roll Force in Asymmetrical Rolling and Its Influence on Rolling Stability.

ISIJ International, 1995
Roll system forces and their relationships with each other during asymmetrical rolling have been studied for deciding the direction and magnitude of the lateral roll forces that could affect the rolling stability, rigidity and loading conditions of a rolling mill.

Subsonic dynamic stability experiment on the anti-tank missile model [PDF]

FME Transactions, 2013
One of the most difficult aspects of aircraft and missile development is defining stability and control characteristics. The best way to obtain model-scale dynamic stability derivatives is to perform experiments in wind tunnels having high Reynolds ...

Numerical study of scale effects of viscous roll damping for a container ship

Brodogradnja
In this paper, the scale effects on a container ship’s roll motion are investigated by numerical approach. The accuracy of the numerical method is verified by comparing numerical results with experimental data through a grid sensitivity study.

The rolling finish of gears by use of a variable rolling force (The relation between the changing position of rolling force and the tooth profile after rolling)

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986
To obtained a tooth profile with high accuracy in the rolling finish of gears, the authors proposed a rolling finish of gears by using a variable rolling force, and then clarified the availability of that method by experiments reported in the previous papers.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
