Analytical methods to predict the surf-riding threshold and the wave-blocking threshold [PDF]

, 1982
For the safe design and operation of high-speed craft it is important to predict their behaviour in waves. There still exists a concern, however, in the framework of the International Maritime Organization (IMO) with regards to the stability criteria. In

Probing the birth of fast rotating magnetars through high-energy neutrinos

, 2009
We investigate the high-energy neutrino emission expected from newly born magnetars surrounded by their stellar ejecta. Protons might be accelerated up to 0.1-100 EeV energies possibly by, e.g., the wave dissipation in the winds, leading to hadronic ...

Prospects for radio detection of ultra-high energy cosmic rays and neutrinos [PDF]

, 2004
The origin and nature of the highest energy cosmic ray events is currently the subject of intense investigation by giant air shower arrays and fluorescent detectors. These particles reach energies well beyond what can be achieved in ground-based particle

On probability of surf-riding in irregular seas with a split-time formulation [PDF]

Ocean Engineering, 2016
The paper reviews the status of a multi-year research effort for using the split-time method to calculate the probability of ship capsizing due to broaching-to in irregular waves. This required taking steps toward extending the existing theory of surf-riding and broaching-to, from regular waves to irregular waves and applying it to numerical simulation

Approximate probability density function for nonlinear surging in irregular following seas

, 2023
The broaching that follows the surf-riding is a dangerous phenomenon that can lead to the capsizing of a vessel due to its violent yaw motion. Most of the previous studies on surf-riding phenomena in irregular waves have been conducted by replacing ...

State-of-the-art and prospects of direct stability assessment methods for second-generation intact stability criteria

Zhongguo Jianchuan Yanjiu
Intact stability of ships in waves is a fundamental guarantee for navigation safety. The direct stability assessment methods associated with the Second Generation Intact Stability Criteria (SGISC) remain undeveloped and have become a key focus of current

A fundamental study on artificial reefs that serve surf-riding points

PROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 1991
After drawing up the left-lettraction diagrams for variable incident waves at the famous surf-riding points in East Shikoku, it was found that the wave convergence and the peel angle (left-lettraction angle at breaking point) were important factors at surfriding. Further, the characteristics of breakers and their peel velocity were measured at straight
