Collision Avoidance Method for Autonomous Ships Based on Modified Velocity Obstacle and Collision Risk Index

Journal of Advanced Transportation, 2022
A novel real-time collision avoidance method for autonomous ships based on modified velocity obstacle (VO) algorithm and grey cloud model is proposed. A typical VO algorithm is used to judge whether there is a collision risk for ships in the potential ...

Grouping-Based Random Access Collision Control for Massive Machine-Type Communication

, 2017
Massive Machine-Type Communication (mMTC) is expected to be strongly supported by future 5G wireless networks. Its deployment, however, is seriously challenged by the high risk of random access (RA) collision. A popular concept is to reduce RA collisions

Estimates of avian collision with power lines and carcass disappearance across differing environments [PDF]

, 2017
Data on collisions of birds with high-voltage electric power lines are scarce and are often gathered without protocols for the correction of carcass disappearance.

Injury risk functions for frontal oblique collisions

Traffic Injury Prevention, 2018
Objective: The objective of this article was the construction of injury risk functions (IRFs) for front row occupants in oblique frontal crashes and a comparison to IRF of nonoblique frontal crashes from the same data set. Method: Crashes of modern vehicles from GIDAS (German In-Depth Accident Study) were used as the basis for the construction of a ...

Measuring Confidentiality Risks in Census Data [PDF]

, 1997
Two trends have been on a collision course over the recent past. The first is the increasing demand by researchers for greater detail and flexibility in outputs from the decennial Census of Population. The second is the need felt by the Census Offices to

A Novel Time-Frame Regional Collision Risk Model Based on Dynamic Time Warping

Journal of Marine Science and Engineering
The quantification of collision risk in the water area is crucial for marine traffic safety. However, most existing studies primarily adopt a statistical perspective or only consider collision risks at discrete time points, neglecting the dynamic nature ...

Evidence in support of the call to ban the tackle and harmful contact in school rugby: a response to World Rugby [PDF]

, 2017
In a paper published in BJSM (June 2016), World Rugby employees Ross Tucker and Martin Raftery and a third coauthor Evert Verhagen took issue with the recent call to ban tackling in school rugby in the UK and Ireland.
