A Ground-penetrating Radar (GPR) survey can enhance the quantity and quality of information when applied to archaeological prospection. The potential of the GPR method lies both in its relevance to a wide range of site conditions and the complementary nature of the data in comparison with other geophysical methods. The areas described in this paper were 'detected' by the Laboratory for Landscape Archaeology and Remote Sensing of University of Siena, during aerial prospection between 2001-2005. Analysis of the aerial photographs allowed interpretation of the Aiali, Castellina and Pava sites, province of Grosseto and Siena (Tuscany, Central Italy). These sites are related to quite a limited chronological range between late Roman and the early mediaeval period. All sites were studied through a multimethodological project based on the integration of fieldwalking and digital global position system (DGPS) surveys combined with different geophysical investigations such as: differential magnetics, ground penetrating radar (GPR) and automatic resistivity profiler (ARP). This paper demonstrates the effectiveness of GPR over the indicated sites characterized by differences in the soil condition and hypothesized archaeological features. With this method a highresolution data acquisition was adopted with the aim of reconstructing the location, depth and shape of the archaeological structures in the selected areas. Signal processing and the time-slice representation technique were used for the analysis of the collected data. Archaeological excavations and interpretations were then conducted systematically after completing the geophysical surveys (from 2006-2009), which confirmed the location and shape of most of the individualized structures. The obtained results demonstrate the accuracy with which GPR data can be matched to excavation data and the improvement in target definition. © 2012 European Association of Geoscientists & Engineers.

A preliminary hydrostratigraphic model of the city of Rome (Italy) was completed through the analysis of geological and hydrogeological data, and by using geographic information system (GIS)-based operations. The complex lithostratigraphic setting of a local Quaternary volcano-sedimentary multilayer was simplified into hydrostratigraphic complexes considering textural properties of terrains and hydraulic conductivity values. The Tiber River Valley, in the middle of the urban area, was analyzed separately from the surrounding areas. GIS tools were used in a multiple-step procedure to reconstruct the geometry of bounding surfaces of the main hydrostratigraphic complexes. Particular care was given to the characterization of a confined gravelly aquifer lying at the base of the upper Pleistocene-Holocene alluvium that fills the Tiber Valley. Updated isobaths and thickness maps of this layer were produced. Three-dimensional reconstruction identifies areas of potential recharge between the alluvium aquifer and the surrounding hydrostratigraphic complexes. In the central sector of the city, the gravel deposits are laterally confined by a thick aquitard corresponding to the Pliocene clayey bedrock of the city; in contrast, a potential recharge area can be hypothesized in the northern areas, where the upper Pleistocene-Holocene valley cross cuts the Paleotiber Graben, filled with older and highly permeable gravels and clays. © 2012 Springer-Verlag.

The aim of "Matera Citt̀ Narrata" (Matera: Tales of a City) project is the creation of a digital platform able to support the public before and during the visit of Matera (Unesco World Heritage since 1993), through the access to cultural contents while attending places, sites, itineraries. It does not consist in a descriptive traditional guide inspecting monuments and mentioning who made them and when. On the contrary it tells the stories that took place in those ancient sites, real fragments of life, myths, events, characters, memories. The main components of the project are: 1) the web site, accessible in remote desktop systems and from smartphone, where it is possible to enjoy narratives, to make specific researches or to download different kinds of materials useful during the successive visit of the city; 2) cultural contents and applications for mobile devices (smartphone, tablet,.mp3 player) with different operative systems (iOS, Android, Symbian, Java). In this way every user can reach cultural contents in a simple way, choosing the communicative format he prefers and supported by the technology he owns. The access is totally free for public. The project has been realized by CNR ITABC and supported by the Regional Promotion Agency (APT) and the Basilicata Regional Government's Department of Manufacturing/Production Activities. Several contents have been developed: 3D reconstructions, videos, multimedia, virtual reality environments, audio guides. The paper will describe the contents and the technological infrastructure. © 2012 IEEE. Source

Along the Italian peninsula adjoin two crustal domains, peri-Tyrrhenian and Adriatic, whose boundary is not univocal in central Italy. In this area, we attempt to map the extent of the Moho in the two terrains from variations of the travel time difference between the direct P wave and the P-to-S wave converted at the crust-mantle boundary, called PsMoho. We use teleseismic receiver functions computed at 38 broad-band stations in this and previous studies, and assigned each of the recording sites to the Adriatic or peri-Tyrrhenian terrains based on station location, geologic and geophysical data and interpretation, and consistency of delays with the regional Moho trend. The results of the present study show that the PsMoho arrival time varies from 2.3 to 4.1 s in the peri-Tyrrhenian domain and from 3.7 to 5.5 s in the Adriatic domain. As expected, the lowest time difference is observed along the Tyrrhenian coastline and the largest values are observed in the axial zone of the Apennine chain. A key new result of this study is a sharp E-W boundary in the Adriatic domain that separates a deeper Moho north of about 42°N latitude from a shallower Moho to the south. This feature is constrained for a length of about 40 km by the observations available in this study. The E-W boundary requires a revision of prior mapping of the Moho in central Italy and supports previous hypotheses of lithosphere segmentation. Key Points Delay of Moho conversions in central Italy are computed at 24 stations Seismic stations are assigned to the Adriatic and peri-Tyrrhenian crust An E-W oriented transition in the Adriatic Moho is inferred ©2013.

Gesture-based interaction models can be efficient and simpler to understand if designed to correspond to common user interactions with the physical world. This paper presents a 3D interface and its implementation to quickly perform navigation and manipulation tasks in multi-scale and multi-resolution 3D scenes using a low-cost consumer sensor: the Leap Motion controller. The developed system has the goal of exploring the potential of accurate hands and fingers tracking alongside mid-air 3D gestures, to investigate specific design advantages and issues they present in such complex environments.
