Effects of surface and internal waves on Unmanned Underwater Vehicles (UUVs)

open access: yes, 2013
In the present work a vertically 2D numerical model is utilized to study the free surface wave kinematics in the absence and presence of a submarine. Description or derivation of formulae is provided that we have used to compute the internal wave amplitude along the interface of fluids of two different densities when free surface wave conditions are ...

Research on the Coupling Dynamics Characteristics of Underwater Multi-Body Separation Considering the Influence of Elastic Constraints

open access: yesJournal of Marine Science and Engineering
Based on the Newton–Euler method, a multi-body coupling dynamics model of the separation process of underwater vehicles is established. The conditions of contact and detachment between the sub-vehicle and each group of elastic gaskets are analyzed in ...

Stochastic modeling, analysis and verification of mission-critical systems and processes [PDF]

open access: yes, 2015
Software and business processes used in mission-critical defence applications are often characterised by stochastic behaviour. The causes for this behaviour range from unanticipated environmental changes and built-in random delays to component and ...
