The Navy and Marine Corps provide the Nation with a flexible and joint instrument of security policy with which to promote stability, project maritime power landward, and exercise American sovereignty abroad. Naval forces shape the global security environment; help assure access to regions of vital interest; and permit timely, and frequently, the initial crisis response from the sea. The abilit...
In the paper the list of authors was incomplete. As a mere management drawback, two coauthors (Luigi Baggi and Michele Di Girolamo) were missing from the paper. They have greatly contributed to the conception of the scientific framework that is posed within the paper, and they have widely contributed to the novel results proposed in the paper. They also oversaw the whole paper. The corrected li...
Online content providers such as YouTube are carefully positioning themselves to users, clients, advertisers and policymakers, making strategic claims for what they do and do not do, and how their place in the information landscape should be understood. One term in particular, ‘platform’, reveals the contours of this discursive work. The term has been deployed in both their populist appeals and...
This paper describes the development of several methods for the dynamic measurement of error distribution for positioning systems. When a user moves along a path at an unknown speed, it is no longer feasible to calculate the distance between the measured and real positions. We outline three applications using different positioning systems and apply our methods to the evaluation of the performan...
The introduction of a new network level protocol called Internet Protocol version 6 (IPv6) represents a significant step forward in the development of the Internet. While IPv6 offers a number of advantages over the current standard (IPv4), its adoption has been inconsistent, often varying by geographic and political region. Through an investigation of early and late adopters of IPv6, this paper...
The objective of this paper is to determine the potentialities of an optimal detection scheme within the framework of subscriber location. Using a Generalized Likelihood Ratio Test (GLRT), an improved first arriving path detector from propagation channel estimates is derived. Furthermore, an expression for false alarm probability is provided and detector performance is evaluated for different c...
Recent developments of automated methods for monitoring animal movement, e.g., global positioning systems (GPS) technology, yield high-resolution spatiotemporal data. To gain insights into the processes creating movement patterns, we present two new techniques for extracting information from these data on repeated visits to a particular site or patch ("recursions"). Identification of such patch...
