High-rate wireless data communications: An underwater acoustic communications framework at the physical layer

A variety of signal processing functions are performed by Underwater Acoustic Systems. These include: 1) detection to determine presence or absence of information signals in the presence of noise, or an attempt to describe which of a predetermined finite set of possible messages {mi,i,...,M} the signal represents; 2) estimation of some parameter θˆ associated with the received signal (i.e. range, depth, bearing angle, etc.); 3) classification and source identification; 4) dynamics tracking; 5) navigation (collision avoidance and terminal guidance); 6) countermeasures; and 7) communications. The focus of this paper is acoustic communications

Mobility, migration, and colonization

Book synopsis: A Companion to the Archaeology of Early Greece and the Mediterranean offers an original and inclusive review of two key periods of Greek archaeology, which are typically treated separately—the Late Bronze Age and the Early Iron Age. It presents an in-depth exploration of the society and material culture of Greece and the Mediterranean, from the 14th to the early 7th centuries BC. The two-volume companion sets Aegean developments within their broader geographic and cultural context, and presents the wide-ranging interactions with the Mediterranean. The companion bridges the gap that typically exists between Prehistoric and Classical Archaeology and examines material culture and social practice across Greece and the Mediterranean. A number of specialists examine the environment and demography, and analyze a range of textual and archaeological evidence to shed light on socio-political and cultural developments. The companion also emphasizes regionalism in the archaeology of early Greece and examines the responses of different regions to major phenomena such as state formation, literacy, migration and colonization
