Comparative Estimation of Maneuverability of the Multi-Track Road Trains of Different Layout Schemes

open access: yesCommunications
Today, in the constructions of multi-link road trains, two main layout schemes are used, as a rule - trailer (car + n trailers) and semi-trailer (tractor car + n semi-trailers). Previously conducted studies established that the maneuverability indicators

Variable- and Fixed-Structure Augmented Interacting Multiple Model Algorithms for Manoeuvring Ship Tracking Based on New Ship Models [PDF]

open access: yes, 2000
The real-world tracking applications meet a number of difficulties caused by the presence of different kinds of uncertainty - unknown or not precisely known system model and random processes’ statistics or due to abrupt changes in the system modes of ...

Maneuverability-Agility Plot (MAP).

open access: yes, 2023
Experimental measurements of freely swimming B. vitrea (red dots) and for all simulated cases of modes 1, 2, and 3 (blue dots). Lower values of indicate sharp turns (more maneuverable); higher values of indicate faster swimming (more agile).

CONDITIONS FOR SAFETY OPERATION AND MANEUVERABILITY OF LOW-TONNAGE ROADTRAIN AT CRITICAL RATES OF MOTION

open access: yesСельскохозяйственные машины и технологии, 2017
The paper deals with the control device for a uniaxial trailer, which makes it possible to increase the maneuverability and reliability of  the movement of a low-tonnage roadtrain by using flexible coupling  in the hitch mechanism. This makes it possible

Vertebral Morphology in Partially Sympatric Dolphins: A 3D Approach

open access: yesFrontiers in Marine Science, 2020
In cetaceans, increased body flexibility is associated with increased maneuverability, this affects the animal’s swimming speed and foraging behavior. A more stable body form is associated with fast swimming and wide turns.

Changes in the Hydrodynamic Characteristics of Ships During Port Maneuvers

open access: yes한국해양공학회지, 2022
To reach a port, a ship must pass through a shallow water zone where seabed effects alter the hydrodynamics acting on the ship. This study examined the maneuvering characteristics of an autonomous surface ship at 3-DOF (Degree of freedom) motion in deep ...
