Sequential growth simulation of (NH(3))(n) clusters (n=2-8) in ultracold superfluid environment
No full textThe growth of ammonia cluster (NH(3))(n) (n = 2-8) in He droplets was studied using a polarizable potential assuming ultrafast heat dissipation and preventing the rearrangement of cluster structures. Energies, structures and isomer statistical distributions were obtained showing that a few high energy isomers may form with a probability similar to low energy ones and that ammonia clusters behave differently from (H(2)O)(n) for n >= 5. Guide by our theoretical analysis, we suggest the need for re-interpreting recent experimental IR spectra of (NH(3))(n) in He droplets for 5 <= n <= 8. (C) 2011 Elsevier B.V. All rights reserved
Energy-aware Routing Algorithm for DTN-Nanosatellite Networks
No full textSatellite constellations are envisioned as meaningful transport networks to forward data throughout the world. Low Earth Orbit (LEO) satellites are the most appealing for this purpose due to their low altitude which allows guaranteeing certain performance, especially in terms of delivery time. Mega-constellation of small LEO satellites (micro- and nano-satellites) are planned to be employed to cover the entire Earth's surface. However, these satellites have several constraints which affect the data forwarding process and have to be taken into account. Energy is one of these constrained resources. Energy storage and recharge are limited by the reduced battery capacity and solar panel surface area, while telecommunication hardware energy consumption is considerable especially in case of high traffic volumes. In this paper, we propose a novel energy-aware routing algorithm based on the Contact Graph Routing (CGR) called E-CGR. E-CGR exploits static and known a priori information about contacts (begin times, end times, and overall contact volumes) to compute complete routing paths from source to destination which are then validated and confirmed from the energy viewpoint

On Tikhonov well-posedness of concave games and Cournot oligopoly
No full textThe purpose of this paper is to investigate whether
theorems known to guarantee the existence and uniqueness for Nash equilibria, provide also
sufficient conditions for the Tikhonov well-posedness.
We have considered several hypotheses that ensure existence and uniqueness of a Nash equilibrium These assumptions imply existence and uniqueness of a
Nash equilibrium but not all assure the well posedness property. We use the oligopoly Cournot model to apply the obtained resuls
Flow Assignment and Processing on a Distributed Edge Computing Platform
No full textThe evolution of telecommunication networks toward the fifth generation of mobile services (5G), along with the increasing presence of cloud-native applications, and the development of Cloud and Mobile Edge Computing (MEC) paradigms, have opened up new opportunities for the monitoring and management of logistics and transportation. We address the case of distributed streaming platforms with multiple message brokers to develop an optimization model for the real-time assignment and load balancing of event streaming generated data traffic among Edge Computing facilities. The performance indicator function to be optimised is derived by adopting queuing models with different granularity (packet- and flow-level) that are suitably combined. A specific use case concerning a logistics application is considered and numerical results are provided to show the effectiveness of the optimisation procedure, also in comparison to a “static” assignment proportional to the processing speed of the brokers
A New Approach to Tikhonov Well-Posedness for Nash Equilibria
No full textIt is suggested a new approach to Tihkonov well-posedness for Nash equilibria. The novelty of our approach consists in a suitable definition
of what could be considered an approximate solution for a Nash equilibrium problem.
Furthermore it can be proved that this property of well-posedness is preserved under monotonic trasformation of the payoffs: a relevant result for economic interpretation
