A Grid Enabled Parallel Hybrid Genetic Algorithm for SPN

2004

This paper presents a combination of a parallel Genetic Algorithm (GA) and a local search methodology for the Steiner Problem in Networks (SPN). Several previous papers have proposed the adoption of GAs and others metaheuristics to solve the SPN demonstrating the validity of their approaches. This work differs from them for two main reasons: the dimension and the features of the networks adopted in the experiments and the aim from which it has been originated. The reason that aimed this work was namely to assess deterministic and computationally inexpensive algorithms which can be used in practical engineering applications, such as the multicast transmission in the Internet. The large dimen…

A Dynamic Distributed Algorithm for Multicast Path Setup

2005

In the past few years, there has been a considerable work on multicast route selection techniques, with the aim to design scalable protocols which can guarantee an efficient use of network resources. Steiner tree-based multicast algorithms produce optimal trees, but they are prohibitively expensive. For this reason, heuristic methods are generally employed. Conventional centralized Steiner heuristics provide effective solutions, but they are unpractical for large networks, since they require a complete knowledge of the network topology. In this paper, we propose a new distributed approach that is efficient and suitable for real network adoption. Performance evaluation indicates that it outp…

An efficient distributed approach for dynamic multicast trees

2005

In this paper we present a distributed algorithm for constructing efficient multicast trees in large networks. The algorithm allows the set up of effective distribution trees using a coordination protocol among the network nodes. The algorithm has been implemented and extensively tested both in simulation, and on experimental networks. Performance evaluation indicates that our approach outperforms the state-of-the-art distributed algorithms for multicast tree setup, providing good levels of convergence time and communication complexity. Furthermore, we introduce a distributed technique for dynamically updating the multicast tree. The approach monitors the accumulated damage as nodes join or…

Una forma di razionalità pratica

2017

Studiosi di diverso orientamento si trovano concordi nell’affermare che la pedagogia è una scienza pratica ovvero una forma della ragion pratica: è una scienza che muove dall’esperienza educativa, come è stato osservato nelle precedenti Lezioni, e all’esperienza intende tornare, come cominceremo ad illustrare in questa Lezione e poi, in modo ancor più determinato, nell’ultima Unità del nostro Corso.

Mette Lebech-Studienführer zu den Beiträgen zur philosophischen Begründung der Psychologie und der Geisteswissenschaften Edith Steins

2011

Die Autorin macht in ihrem Abstract deutlich, dass die Absicht des veröffentlichten Studienführers darin besteht, in Bezug auf Edith Steins Philosophy of Psychology and the Humanities (vgl. GERL-FALKOVITZ, H.-B. [Hrsg.], Edith Stein Gesamtausgabe «ESGA», Band 6, Beiträge zur philosophischen Begründung der Psychologie und der Geisteswissenschaften, eingeleitet und bearbeitet von BECKMANN-ZÖLLER, B., Freiburg, Herder 2010) als Hilfe der Lektüre, Deutung und Anwendung zu fungieren. Der kürzlich bei Herder in kritischer Neuausgabe erschienene Band verleiht dem Leitfaden eine prägnante Aktualität. Lebechs Interpretationen innerhalb des Leseleitfadens gereichen zu neuen Verständnisbrücken und zu …

Narrare con il COVID19. Storie di qualità per i bambini della prima infanzia

2020

This contribution aims to offer a reflection on storytelling in early childhood. It plays a fundamental role in training and development of the person, especially as far as emotion is concerned, as it constitutes an attempt to translate part of one's inner world into words, thanks to the aid of a literary genre that allows one to represent and socialize it in culturally defined ways. The training process is always peculiarly narrative: one tells and everyone expresses himself; the training process is intrinsically relational and in this very relationality the negotiation of one's self with that of others is an element of vital importance. In this sense, storytelling can be considered valid …

Steiner Loops of Affine Type

2020

Steiner loops of affine type are associated to arbitrary Steiner triple systems. They behave to elementary abelian 3-groups as arbitrary Steiner Triple Systems behave to affine geometries over GF(3). We investigate algebraic and geometric properties of these loops often in connection to configurations. Steiner loops of affine type, as extensions of normal subloops by factor loops, are studied. We prove that the multiplication group of every Steiner loop of affine type with n elements is contained in the alternating group An and we give conditions for those loops having An as their multiplication groups (and hence for the loops being simple).
