Clustering in \({}^{11,12,13}\)C

L. Palada, Neven Soić, Luis Acosta, Sam Bailey et autres

Characterization of the excited states of 11C, 12C, 13C isotopes was performed using experimental data collected at the INFN-LNL in Italy. The study employed a 95 MeV 14N beam on 10B targets to probe clustering phenomena in carbon isotopes. The experimental setup …

Poster: Modeling Congestion Control using Petri Nets

Guillem Duran, José M. Amigó, Ángel Giménez, José Valero et autres

Formal specification is an essential phase for the design of any network algorithm, including Active Queue Management (AQM) schemes. In this poster, we focus on modeling with Petri Nets (PN) a new scheme of AQM. Our AQM is based on a discrete …

Modeling a New AQM Model for Internet Chaotic Behavior Using Petri Nets

José M. Amigó, Guillem Duran, Ángel Giménez, José Valero et autres

Formal modeling is considered one of the fundamental phases in the design of network algorithms, including Active Queue Management (AQM) schemes. This article focuses on modeling with Petri nets (PNs) a new scheme of AQM. This innovative AQM is based on a …

Bifurcation analysis for the Internet congestion

Guillem Duran, José Valero, José M. Amigó, Ángel Giménez et autres

The bifurcation and chaotic behavior of TCP may cause heavy oscillation of average queue length at routers and induce network instability. In this context, congestion control in the Internet is a challenging problem of key importance. This work presents a new discrete …

Stabilizing Chaotic Behavior of RED

Guillem Duran, José M. Amigó, Ángel Giménez, Óscar Martínez

The Internet is a so complex nonlinear network that many results show how the data flow exhibits chaotic attributes and the fractal nature of aggregate TCP/IP traffic. In this work, we study a new model of Random Early Detection (RED) using beta …

Happiness, an inside job?

Jose Oriol Lopez Berengueres, Guillem Duran, Dani Castro

In this paper, we describe how to rank employees for risk of turnover by using data obtained from a happiness self-reporting app. Two data sources are used: daily happiness and social interactions. The data spans 2.5 years and 4,356 employees of 34 …

General Algorithmic Search

Sergio Hernández, Guillem Duran, José M. Amigó

In this paper we present a metaheuristic for global optimization called General Algorithmic Search (GAS). Specifically, GAS is a stochastic, single-objective method that evolves a swarm of agents in search of a global extremum. Numerical simulations with a sample of 31 test …
