Detached Eddy Simulation of the Flow Behind an Isolated Propeller |
The turbulent flow behind a rotating marine propeller is analysed by integration of the Reynolds-Averaged Navier-Stokes Equations with both the Spalart & Allmaras (1994) eddy viscosity model and by a Detached Eddy Simulation approach (Spalart et al 1997) in order to assess advantages and limits… | |
On the use of synchronous and asynchronous single-objective deterministic particle swarm optimization in ship design problems |
. A guideline for an effective and efficient use of a deterministic variant of the Particle Swarm Optimization (PSO) algorithm is presented and discussed, assuming limited computational resources. PSO was introduced in Kennedy and Eberhart (1995) and successfully applied in many fields of… | |
CFD analysis of propeller-rudder interaction |
Interaction of the vortex systems detached from a propeller with a rudder installed in its wake is investigated by CFD. The correct prediction of this phenomenon is of great interest in naval hydrodynamics research, it being the source of irradiated noise and vibratory loads. The phenomenology is… | |
Generalizing Wiener Estimator to frame operators |
In this paper the Wiener estimator for signal-denoising is generalized to finite frame operators. In particular, a two-stage procedure which results in a non-linear and non-diagonal estimator is proposed. Advantages and disadvantages with respect to the classical Wiener estimator used with… | |
A double dynamic fast algorithm to solve multi-vehicle Dial a Ride Problem |
In this work a two level heuristic algorithm is described for a nearly real-time multi-vehicle many-to-many Dial-A-Ride Problem (DARP). This algorithm is ready to support a Demand Responsive Transportation System in which we face the problem of quickly evaluate a good-quality schedule for the… | |
Non solo ornamenti. Parures e oggetti-simbolo dalle tombe dei principi indigeni dell'area apulo-lucana |
The archaeological discoveries of recent years and the latest studies about the uses and customs of Italic aristocracies of the Apulian-Lucanian area have added some relevant data concerning to the class of personal adornments and symbolic objects, fundamental elements underpinning the phenomenon… | |
Exact and metaheuristic approaches to extend lifetime and maintain connectivity in wireless sensors networks |
Wireless sensor networks involve a large area of real-world contexts, such as national security, military and environmental control applications, traffic monitoring, among others. These applications generally consider the use of a large number of low-cost sensing devices to monitor the activities… | |
