Formation of three-dimensional surface waves on deep-water using elliptic solutions of nonlinear Schrödinger equation
Shahrdad G. Sajjadi, Stefan C. Mancas, Frederique Drullion
A review of three-dimensional waves on deep-water is presented. Three forms of three dimensionality, namely oblique, forced and spontaneous type, are identified. An alternative for…
Existence of periodic orbits in nonlinear oscillators of Emden-Fowler form
S. C. Mancas, H. C. Rosu
The nonlinear pseudo-oscillator recently tackled by Gadella and Lara is mapped to an Emden-Fowler (EF) equation that is written as an autonomous two-dimensional ODE system for whic…
Barotropic FRW cosmologies with Chiellini damping
Haret C. Rosu, Stefan C. Mancas, Pisin Chen
It is known that barotropic FRW equations written in the conformal time variable can be reduced to simple linear equations for an exponential function involving the conformal Hubbl…
One-parameter supersymmetric Hamiltonians in momentum space
Haret C. Rosu, Stefan C. Mancas, Pisin Chen
Recent results on the one-parameter supersymmetric deformation in momentum space by Curtright and Zachos (2014 J. Phys. A: Math. and Theor. 47 145201; arXiv:1311.6147v2) are presen…
Variable viscosity condition in the modeling of a slider bearing
Kedar Nath Uprety, Stefan C. Mancas
To reduce tear and wear of machinery lubrication is essential. Lubricants form a layer between two surfaces preventing direct contact and reduce friction between moving parts and h…
Micro cavitation bubbles on the movement of an experimental submarine Theory and Experiments
Stefan C. Mancas, Shahrdad G. Sajjadi, Asalie Anderson +1
To further understand their nature, micro cavitation bubbles were systematically diffused around the exterior of a test body (tube) fully submerged in a water tank. The primary pur…
