Performance evaluation of a measurement-based algorithm for distributed admission control in a DiffServ framework
2002
Distributed Admission Control in IP DiffServ environments is an emerging and promising research area. Distributed admission control solutions share the idea that no coordination among network routers (i.e. explicit signaling) is necessary, when the decision whether to admit or reject a new offered flow is pushed to the edge of the IP network. Proposed solutions differ in the degree of complexity required in internal network routers, and result in a different robustness and effectiveness in controlling the accepted traffic. This paper builds on a recently proposed distributed admission control solution, called GRIP (Gauge&Gate Reservation with Independent Probing), designed to integrate the …
Polyoxometalate-Based Molecular Materials.
1998
Molecule-based materials with active physical properties, in particular electrical, magnetic, and optical, are a focus of contemporary materials chemistry research. Certainly, one reason for this interest has been the realization that these materials can exhibit cooperative properties typically associated with the inorganic network solids, as for example metallic conduction or even superconductivity,1 ferromagnetism,2 and nonlinear optical properties.3 With respect to the electrical properties, many important achievements were obtained in the 1970s with the discovery of the first molecule-based metal in 1972,4 namely the π-electron donor-acceptor complex [TTF][TCNQ] (TTF ) tetrathiafulvalen…
La comunità educante di fronte alla pandemia: possibili strategie di intervento e nuovi scenari in un’ottica di rete
2022
Quando nel mese di marzo 2020, anche i servizi educativi 0-6 in Italia furono chiusi in base alle misure di sicurezza per pandemia da Covid 19, ci si ritrovò da un giorno all’altro e senza alcuna esperienza pregressa, ad organizzare delle forme di educazione a distanza e di sostegno alle famiglie e ai bambini. Nell’articolo, in particolare, descrivo come si è cercato di far fronte all’emergenza nei nidi e nelle scuole dell’infanzia gestiti dal Comune di Palermo e come l’esperienza del primo lock down abbia permesso di mettere a fuoco alcune strategie di intervento che si sono rivelate una risorsa potenzialmente trasferibile in situazioni di normalità. Sottolineo, inoltre, come la necessità …
Information Transfer in Linear Multivariate Processes Assessed through Penalized Regression Techniques: Validation and Application to Physiological N…
2020
The framework of information dynamics allows the dissection of the information processed in a network of multiple interacting dynamical systems into meaningful elements of computation that quantify the information generated in a target system, stored in it, transferred to it from one or more source systems, and modified in a synergistic or redundant way. The concepts of information transfer and modification have been recently formulated in the context of linear parametric modeling of vector stochastic processes, linking them to the notion of Granger causality and providing efficient tools for their computation based on the state&ndash
StateOS : A Memory-Efficient Hybrid Operating System for IoT Devices
2023
The increasing significance of operating systems (OSs) in the development of the internet of things (IoT) has emerged in the last decade. An event-driven OS is memory efficient and suitable for resource-constrained IoT devices and wireless sensors, although the program’s control flow, which is determined by events, is not always obvious. A multithreaded OS with sequential control flow is often considered clearer. However, this approach is memory-consuming. A hybrid OS seeks to combine the strengths of the event-driven approach with multithreaded approach. An event-driven cooperative threaded OS represents a hybrid approach that supports concurrency by explicitly yielding control to another …
Col : A Data Collection Protocol for Vanet
2012
International audience; In this paper, we present a protocol to collect data within a vehicular ad hoc network (VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers three relevant properties: (1) It allows any vehicle to collect data beyond its direct neighborhood (i.e., vehicles within direct communication range) using vehicle-to-vehicle communications only (i.e., the infrastructure is not required); (2) It tolerates possible network partitions; (3) It works on demand and stops when the data collection is achieved. To the best of our knowledge, this is the first collect protocol having these three characteristics. All that is chiefly obtained thanks…
Shared Sequences from Network Therapy with Adolescents Only the therapist Finds Meaningful
2016
As part of a larger research project, this qualitative study explores sequences from six network therapy sessions. We focused on these sequences because only the therapists found them to be meaningful; the other participants did not think they were significant. The aim of this study was to explore the therapists’ inner dialogues, the degree to which these inner dialogues consist of professional and personal voices, and what this means for the dialogical process. We used a multi-perspective methodology that combines video recordings of network therapy sessions, participants’ interviews, and text analysis. We found that the outer dialogue and the therapists’ inner dialogues are strongly relat…
IMPATTO DELLA CHIMICA NELLA VITA QUOTIDIANA: UN PROGETTO DEL NETWORK EC2E2N 2
2013
Il progetto si pone come obiettivo la realizzazione di “Studi di Caso”, esemplificativi in aree in cui la Chimica ha un ruolo determinante e che dimostrino l’impatto di questa scienza nella vita quotidiana. Gli esempi scelti, dovranno essere specifici, attraenti e interessanti anche per un pubblico privo di basi scientifiche. Inoltre, si realizzeranno un certo numero di quesiti online, attraverso i quali il pubblico potrà anche valutare la propria consapevolezza di tale impatto.
Network interimpresa ed opportunità imprenditoriali: il ruolo dei legami deboli e forti nella formazione e nello sfruttamento delle opportunità impre…
2018
L'obiettivo del lavoro è indagare il ruolo dei legami deboli tra imprese nel processo di identificazione del set di potenziali partner di valore tra i quali scegliere con chi attivare legami forti, formalizzati in alleanze, che consentano di sfruttare opportunità imprenditoriali scoperte o create. Numerosi studi manageriali si sono soffermati ad analizzare l'emersione e le dinamiche evolutive della struttura dei network di alleanze ed hanno, complessivamente, individuato le differenti finalità e le logiche di formazione che contraddistinguono due categorie di legami forti: i legami locali che si formano all'interno di cluster appartenenti al network; i bridging ties, che creano ponti tra pa…
Analysis of network rumor dissemination and control mechanisms on Chinese social network : Sina Weibo
2016
The social network has become a major source of information. The openness and swiftness of the network bring instant accessing to both true and false information. Sometimes the false information such as network rumors can mislead people from obtaining the true information and even create chaos. The social network platforms and the governments in different countries are making effort on enacting their own mechanisms to strive on eliminating the rumors. The aim of this thesis is to investigate the spreading of rumors on the Chinese social networking website Sina Weibo. The censorship policy of the Chinese government and the methods used to control the spreading of rumors are discussed. The la…
