Measurement Based Reconfigurations in Optical Ring Metro Networks
No full textSingle-hop wavelength division multiplexing (WDM) optical ring networks operating in packet mode are one of themost promising architectures for the design of innovative metropolitan network (metro) architectures. They permit a cost-effective design, with a good combination of optical and electronic technologies, while supporting features like restoration and reconfiguration that are essential in any metro scenario. In this article, we address the tunability requirements that lead to an effective resource usage and permit reconfiguration in optical WDM metros.We introduce reconfiguration algorithms that, on the basis of traffic measurements, adapt the network configuration to traffic demands to optimize performance. Using a specific network architecture as a reference case, the paper aims at the broader goal of showing which are the advantages fostered by innovative network designs exploiting the features of optical technologies
University inclusion at the time of COVID-19: a pilot study
No full textIn line with the pedagogical movement called Student Voice (Cook-Sather, 2014), a research group in the Pedagogy and Special Didactics field, from the University of Macerata, has carried out a pilot study with University students with disabilities and with Specific Learning Disorders (Giaconi, Capellini, 2015; Del Bianco, 2019). Specifically, the study will deepen how the Voices of all students can be recorded even during an emergency period and how students' feedback can be the first step to start new cooperation in the implementation of educational paths
Crystallographic characterization of geometry and conformation of TOAC, a nitroxide spin-labelled C-alpha,C-alpha-disubstituted glycine, in simple derivatives and model peptides
No full textThe molecular and crystal structures of one derivative and two oligopeptides of TOAC, a nitroxide spin-labelled C-alpha,C-alpha-disubstituted glycine, have been determined by X-ray diffraction. The derivative is the 5(4H)-oxazolone from Piv-TOAC-OH; the oligopeptides are Z-TOAC-(L-Ala)(2)-NHtBu sesquihydrate and pBrBz-TOAC-(L-Ala)(2)-TOAC-L-Ala-NHtBu hemihydrate. Incipient and fully developed right-handed 3(10)-helical conformations are formed by both independent molecules in the asymmetric unit of the terminally blocked tripeptide amide and the terminally blocked pentapeptide amide, respectively. The average geometry and preferred conformation for the piperidine ring of the TOAC residues are also discussed in detail. (C) Munksgaard 1996

La disabilità nei media digitali: opportunità e rischi
No full textIl capitolo affronta il tema della disabilità in relazione all'uso dei media digitali indagando due specifiche questioni: la rappresentazione sociale della disabilità nei vari flussi comunicativi offline e online e l’aspetto relativo all’offerta delle tecnologie digitali che contribuiscono a formare l’integrazione scolastica, lavorativa e relazionale
The development of growth rings on ancient glass surfaces: Description and simulation of the weathering
No full textThe present work investigates the weathering process of glass surfaces with the formation of corrosion growth rings investigated by
X-ray photoelectron spectroscopy, optical microscope, environmental scanning electron microscope and particle induced X-ray emission.
The analysed samples are both ancient and recent glasses. The first set of samples is constituted by Roman glass fragments originally
belonging to the load of the Iulia Felix ship, sunken in the Northern Adriatic sea (Grado, Italy) during II century AD. The samples
were already investigated in the past [F. Barbana, R. Bertoncello, L. Milanese, C. Sada, J. Non-Cryst. Solids 337 (2) (2004) 136; B. Dal
Bianco, R. Bertoncello, L. Milanese, S. Barison, J. Non-Cryst. Solids 343 (2004) 91; B. Dal Bianco, R. Bertoncello, L. Milanese, S. Barison,
Surface Eng. 21 (5–6) (2005) 393; B. Dal Bianco, R. Bertoncello, L. Milanese, S. Barison, Archaeometry 47 (2) (2005) 353], but their
production process is still unknown. The second set of samples belongs to the stained window of S. Giovanni church in Polegge (Vicenza,
Italy) and it is dated to 1930 ca. The glass production process is well known. In fact, every tessera is made of soda-lime glass. On one side
only, the glass is coated with a green pigment (low melting temperature glass) and then heated in oven in order to fix it on the glass. The
window is then mounted and fixed to the wall. Unfortunately, during this procedure, the window was positioned inside-out, so that the
painted surface was exposed to the direct action of the atmospheric conditions. This anomaly favoured the fast degradation of the tessera,
with the presence of concentric rings at the surface. Another set of samples was produced in order to simulate the effects of moisture
at the glass surface, using an industrial soda-lime glass and coating it with a painting originally used in 1930s. The comparisons between
the corrosion of the three sets of samples suggest that the Iulia Felix glasses could have been prepared with the same technique.
