Optimization in bioventing: modeling and air flow field evaluation |
Bioventing is an in site remediation technique, which is useful for decontaminating polluted subsoil. Air is injected into the subsoil to enhance the bacteria biodegradation activity. A multiphase mathematical model describing the removal of hydrocarbon in the unsaturated zone will be described and… | |
Hydrodynamical Numerical Simulations of Complex-Shaped Moving Bodies by means of Dynamic Overlapping Grids |
In this work the numerical simulations of a submarine in straight ahead motion with the appendages at several prescribed deflection angles are performed. Due to the complex geometry involved (the presence of moving appendages), these simulations are rather demanding form the point of view of both… | |
Measurement and modeling of turbulent boundary layer excitation for naval and aeronautial applications |
The correct characterization of wall pressure fluctuations (WPF) and of the response of an elastic structure subjected to turbulent boundary layer (TBL) represents one of the most challenging problems in the fluid structure interaction field. This kind of excitation for an elastic structure is… | |
LES-SPH model for weakly-compressible Navier-Stokes equations |
The Smoothed Particle Hydrodynamics (SPH) method is revisited within a Large Eddy Simulation (LES) perspective following the recent work of [1]. To this aim, LES filtering procedure is recast in a Lagrangian framework by defining a filter centred at the particle position that moves with the… | |
Network-Aware Evaluation Environment for Reputation Systems |
Parties of reputation systems rate each other and use ratings to compute reputation scores that drive their interactions. When deciding which reputation model to deploy in a network environment, it is important to find the most suitable model and to determine its right initial configuration. This… | |
SLAP: Secure Lightweight Authentication Protocol for Resource-constrained Devices. |
Motivated by the upcoming Internet of Things, designing light-weight authentication protocols for resource constrained devices is among the main research directions of the last decade. Current solutions in the literature attempt either to improve the computational efficiency of cryptographic… | |
AMG Preconditioners based on Parallel Hybrid Coarsening and Multi-objective Graph Matching |
We describe preliminary results from a multiobjective graph matching algorithm, in the coarsening step of an aggregation-based Algebraic MultiGrid (AMG) preconditioner, for solving large and sparse linear systems of equations on highend parallel computers. We have two objectives. First, we wish to… |
