Cartografia archeologica di base del sito di Elaiussa Sebaste da immagini satellitari ad alta risoluzione geometrica

2009

This paper sets out the research work carried out by the Unit of Palermo University within the FIRB 2003 National Programme, directed to the compilation of an archaeological base map of the Roman site at Elaiussa Sebaste. The employed methodology is based on the use of high resolution satellite imagery; particularly, a QuickBird image was used. A GPS survey was carried out in September 2008, aimed at determination of ground control points and spot heights used to georeference the image and to construct the DTM respectively. At last a digital orthophoto of the archaeological area was compiled from the acquired data.

Monitoraggio della diga “Castello” di Bivona (AG) con tecniche GNSS

2012

Le dighe di grandi dimensioni, di terra o di cemento, sono infrastrutture che rivestono un ruolo critico nella fornitura idrica e nella produzione energetica. Come è noto in letteratura, il carico e lo scarico delle forze sottopone la diga a elevate sollecitazioni strutturali che devono essere monitorate. Queste possono essere dovute alle fluttuazioni del livello dell'acqua, all'assestamento della struttura, all'attività di frane situate nelle vicinanze o all'attività sismica. Rilevare preventivamente i potenziali problemi consente di adottare le misure necessarie per evitare che si verifichi una catastrofe, o mitigarne gli effetti. Il lavoro proposto è in corso di svolgimento presso il Dip…

Approccio differenziato per la validazione dei dati GPS provenienti dalla rete UNIPA

2011

In questo lavoro ci si è proposti la verifica di qualità iniziale e la successiva elaborazione delle osservazioni provenienti dalle stazioni permanenti appartenenti alla rete dell’Università di Palermo, creata nell’ambito del progetto PRIN2005 dal titolo: “Reti di stazioni permanenti GPS per il rilievo in tempo reale in impieghi di controllo e emergenza” e gestita dal Dipartimento di Ingegneria Civile, Ambientale e Aerospaziale. Tale rete attualmente è formata da nove stazioni permanenti localizzate presso la Facoltà di Ingegneria dell’Università di Palermo e altri istituti o enti pubblici presenti nelle località di Termini Imerese (PA), Trapani, Agrigento, Caltanissetta, Partinico (PA), Ca…

Il Rilievo MMS di tracciati autostradali

2009

Già da alcuni anni alcuni autori hanno messo in risalto come, anche in ambito autostradale, la geometria d’asse intesa come il complesso plano-altimetrico degli elementi di tracciato, eserciti un ruolo non marginale sulla condotta di guida dell’utente. Grazie alle metodologie di verifica della coerenza della linea d’asse di tracciato (Design Consistency), si accerta o meno che esista un’armonica correlazione tra parametri geometrici significativi e la velocità, di progetto od operativa, del tronco considerato. L’espressione grafica di tale correlazione è il cosiddetto diagramma delle velocità, dalla cui analisi, secondo criteri invero peculiari di infrastrutture viarie non autostradali, è p…

A bio-imitating approach to fabricate an artificial matrix for cartilage tissue engineering using magnesium-polyphosphate and hyaluronic acid

2016

Here we describe an artificial cartilage-like material based on a hyaluronic acid-Mg/Ca-polyphosphate paste (HA-aMg/Ca-polyP-p) that is fabricated from a water-soluble Na-salt of energy-rich inorganic polyphosphate (polyP) and soluble hyaluronic acid in the presence of water-insoluble CaCO3. The resulting material, after conversion of Na-polyP into the less soluble Mg/Ca-salt consisting of amorphous Mg/Ca-polyP microparticles, was found to mimic the physiological cartilage tissue and to bind Ca2+ ions present in the synovial fluid. After the Mg2+/Ca2+ exchange and water extrusion, the polyP becomes more stable, but is still susceptible to hydrolytic cleavage by the alkaline phosphatase (ALP…

Approximation Algorithms for Multicoloring Planar Graphs and Powers of Square and Triangular Meshes

2006

A multicoloring of a weighted graph G is an assignment of sets of colors to the vertices of G so that two adjacent vertices receive two disjoint sets of colors. A multicoloring problem on G is to find a multicoloring of G. In particular, we are interested in a minimum multicoloring that uses the least total number of colors. The main focus of this work is to obtain upper bounds on the weighted chromatic number of some classes of graphs in terms of the weighted clique number. We first propose an 11/6-approximation algorithm for multicoloring any weighted planar graph. We then study the multicoloring problem on powers of square and triangular meshes. Among other results, we show that the infi…

On operads, bimodules and analytic functors

2017

We develop further the theory of operads and analytic functors. In particular, we introduce a bicategory that has operads as 0-cells, operad bimodules as 1-cells and operad bimodule maps as 2-cells, and prove that this bicategory is cartesian closed. In order to obtain this result, we extend the theory of distributors and the formal theory of monads.

A new Meckel's cartilage from the Devonian Hangenberg black shale in Morocco and its position in chondrichthyan jaw morphospace.

2022

Fossil chondrichthyan remains are mostly known from their teeth, scales or fin spines only, whereas their cartilaginous endoskeletons require exceptional preservational conditions to become fossilized. While most cartilaginous remains of Famennian (Late Devonian) chondrichthyans were found in older layers of the eastern Anti-Atlas, such fossils were unknown from the Hangenberg black shale (HBS) and only a few chondrichthyan teeth had been found therein previously. Here, we describe a Meckel’s cartilage from the Hangenberg black shale in Morocco, which is the first fossil cartilage from these strata. Since no teeth or other skeletal elements have been found in articulation, we used elliptica…
