NRN106 - A High-Order Stabilised ALE Finite Element Formulation for the Euler Equations on Deformable Domains
This paper presents a high-order accurate stabilised finite element formulation for the simulation of transient inviscid flow problems in deformable domains. This work represents an extension of the methodology described in Sevilla et al. (2013), where a high-order stabilised finite element formulation was used as an efficient alternative for the simulation of steady flow problems of aerodynamic interest.
NRN147 - Subcarrier Index-Power Modulated Optical OFDM with Superposition Multiplexing for IMDD PON Systems
In this paper, extensive numerical explorations of SIPM-OOFDM-SPM performance characteristics are undertaken, based on which optimum transceiver design parameters are identified. For IMDD PON systems, it is shown that SIPM-OOFDM-SPM considerably improves the signal transmission capacity, link power budget, and system performance tolerances to both chromatic dispersion and fiber nonlinearity.
NRN045 Dynamics and Stability of Mutually Coupled Nano-Lasers
The dynamics of mutually coupled nano-lasers has been explored theoretically. Calculations have been performed using rate equations which include the Purcell cavity-enhanced spontaneous emission factor F and the spontaneous emission coupling factor β.
NRNG05 A new Jameson–Schmidt–Turkel Smooth Particle Hydrodynamics Algorithm for Large Strain Explicit Fast Dynamics
This paper presents a new Smooth Particle Hydrodynamics (SPH) computational framework for large strain explicit solid dynamics. A mixed-based set of Total Lagrangian conservation laws (Bonet et al., 2015; Gil et al., 2016) is presented in terms of the linear momentum and an extended set of geometric strain measures, comprised of the deformation gradient, its co-factor and the Jacobian.
