    The Early Bronze Age III and IVA1 at Tell Mardikh/Ebla and Its Region : Stratigraphic and Ceramic Sequences

    No full text
    The site of Tell Mardikh, ancient Ebla, in north inner Syria, had three periods of flourishing: in Early Bronze IVA, the age of the State Archives, Early Bronze IVB and Middle Bronze I–II, between ca. 2400 and 1600 BC. The volume by Agnese Vacca explores the phases of formation of this great urban culture between ca. 2750/2700 and 2450 BC (EB III–IVA1) by means of an accurate and in-depth analysis of stratigraphy, architecture, ceramic materials and small finds. The analysis was carried out in part on the field, but it is also the brilliant result of a painstaking work of study of excavation records and files from the archives of the Ebla Excavation, which allowed the author to collect consistent evidence from individual buildings – like Building G2 and Building G5 – and to relate it with scattered evidence from other sectors of the town, leading to the reconstruction of a coherent picture of pre-Palace G phases. As concerns specifically the ceramic repertory, Vacca, starting with the evidence from Ebla, enlarges her analysis, singling out a specific pottery horizon of the Ebla region, whose relations with other contemporary assemblages in the Northern Levant are presented in detail. The resulting picture from Ebla and its region has been related with the contemporary evidence from the Northern Levant and Upper Mesopotamia and has been framed in the general background of the process of state formation in this very important region of the ancient Near East

    Understanding route switch behavior: An analysis using GPS based data

    No full text
    The objective of this paper is to study route switch behavior to detect which trip and individual characteristics most influence the choice of multiple routes for the same origin-destination (OD) trip. In this study we used a database of 361 morning commute trips, regarding 66 users, collected in the metropolitan area of Cagliari (Italy) during the “Casteddu Mobility Styles” survey. Data were collected for a 14 days period through a personal probe system called Activity Locator (Meloni, et al., 2011), a smartphone that integrates a GPS logger for the acquisition of the routes and an activity/travel diary. Mixed logit models are estimated, in order to take into account the variability of user perception. Results show that route switch behavior is influenced by the number of traffic lights per km, percent of highways, time perception, gender, age, individual income and driving experience in relation with the minutes per km

    Quantum Dot Cellular Automata Check Node Implementation for LDPC Decoders

    The quantum dot Cellular Automata (QCA) is an emerging nanotechnology that has gained significant research interest in recent years. Extremely small feature sizes, ultralow power consumption, and high clock frequency make QCA a potentially attractive solution for implementing computing architectures at the nanoscale. To be considered as a suitable CMOS substitute, the QCA technology must be able to implement complex real-time applications with affordable complexity. Low density parity check (LDPC) decoding is one of such applications. The core of LDPC decoding lies in the check node (CN) processing element which executes actual decoding algorithm and contributes toward overall performance and complexity of the LDPC decoder. This study presents a novel QCA architecture for partial parallel, layered LDPC check node. The CN executes Normalized Min Sum decoding algorithm and is flexible to support CN degree dc up to 20. The CN is constructed using a VHDL behavioral model of QCA elementary circuits which provides a hierarchical bottom up approach to evaluate the logical behavior, area, and power dissipation of the whole design. Performance evaluations are reported for the two main implementations of QCA i.e. molecular and magneti
