Il ruolo della piattaforma continentale nord-adriatica nel Paleolitico superiore
No full textGli autori mettono in evidenza il ruolo che ebbe nel Paleolitico superiore la piattaforma continentale alto-adriatica, emersa durante l'Interpleniglaciale e il Secondo Pleniglaciale würmiani. Nell'Inter-pleniglaciale alcuni gruppi dei primi Uomini Moderni che dal Vicino Oriente migrarono in Europa attraverso la Penisola Balcanica ebbero accesso alla Penisola Italiana e alla regione ligure-provenzale superando le modeste alture delle Alpi Dinariche Marittime e dell'Appennino settentrionale. La distribuzione dei siti protoaurignaziani, i materiali litici, la tipologia delle armature e le parures suggeriscono direttrici sud-alpine ed appenniniche û nora trascurate. Nel Secondo Pleniglaciale würmiano la distribuzione di materiali litici di qualità provenienti dall9Appennino umbro-marchigiano e utilizzati per la fabbricazione di gravettes, microgravette e pointes à cran evidenzia la loro circolazione nella grande pianura ora sommersa.
I siti istriani documentano anche la raccolta di ciottoli silicei dai vasti depositi ü uvioglaciali situati a valle dell'anfiteatro morenico del Tagliamento.ABSTRACT − The Authors put on evidence the role that in the Upper Paleolithic played the Northern Adriatic continental platform, which emerged during the Inter-Pleniglacial and the Last Glacial Maximum. During the Inter-Pleniglacial some groups of Early Modern Humans, migrating from the Middle East to Europe 12through the Balkan Peninsula, could reach the Italian Peninsula and the Ligurian-Provençal region crossing the low hills of the Maritime Dinaric Alps and of the Northern Apennines. e distribution of the Protoaurignacian sites, the exploited lithic raw materials , the armatures typology and the parures suggest Southern Alpine and Apennine routes till now neglected. In the Last Glacial Maximum the distribution of high quality blade and bladelets lithic artifacts (gravettes, microgravettes and pointes à cran) made with high quality cherts from the Umbria-Marches Apennines, highlights their wide circulation in the Northern Adriatic paleo plain now submerged. e Istria Peninsula sites also attest the gathering and exploitation of fl uvioglacial chert cobbles distributed in the vast alluvial plain south of the Tagliamento morainic amphitheater

Generalizing virtual network topologies in OpenFlow-based networks
No full textNetwork Virtualization (NV) is one of the most promising technique to enable innovation in today's network. A recent approach toward NV has been proposed through FlowVisor, whose aim is to leverage on the specific features of an OpenFlow-controlled network to share the same hardware forwarding plane among multiple logical networks. However, FlowVisor lacks some features to enable a full implementation of a NV architecture: the virtual topologies that can be established are restricted to subsets of the physical topology and it has no way for two slices to share flowspace and simultaneously prevent them from interfering with each other's traffic. In this work, an innovative system called ADVisor (ADvanced FlowVisor) which enhances FlowVisor while overcoming its major constraints is presented and a set of experimental results discussed to demonstrate its capability to provide an effective support toward a Network Virtualization architecture
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Demonstrating generalized virtual topologies in an openflow network
No full textNetwork Virtualization (NV) is one of the most promising
approaches to enable innovation in today’s network. Generally
speaking, NV refers to the possibility of pooling together
low–level hardware and software resources belonging
to a networked system into a single administrative entity. In
such a way network resources could be effectively shared in
a transparent way among different logical network instances
corresponding to different virtual network topologies.
A recent approach toward Network Virtualization has been
proposed through FlowVisor [1], whose aim is to leverage on
the specific features of an OpenFlow–controlled network [2]
to share the same hardware forwarding plane among multiple
logical networks
The role of the Northern Adriatic region in the Protoaurignacian spread towards Mediterranean Europe
No full textBesides the accepted hypothesis of a Danubian -
Northern Alpine route, the evidences discussed in
this paper constitute strong indications in favor of
another possible route followed by the Protoaurignacian
groups: from the Balkans trough the Julian
and Dinaric Alps and the emerged Northern Adriatic
land to the Mediterranean Europe.
Between the Balkan and the Italian Peninsulas
there were not insuperable barriers: probably some
Protoaurignacian groups crossed this territory, settling
in the Venetian Prealps or reaching the Liguria
and the French Riviera across the Apennine and supposedly
arriving also to the Apulian and Campanian
sites. The raw materials provenance, the common
techno-typological features of the lithic industries
and similar decorative elements seem valid arguments,
also supported by chronological data
