Collusion-Resistant Fingerprinting for Multimedia in a Broadcast Channel Environment. (December 2004) William Luh, B.A., University of Toronto Chair of Advisory Committee: Dr. Deepa Kundur Digital fingerprinting is a method by which a copyright owner can uniquely embed a buyer-dependent, inconspicuous serial number (representing the fingerprint) into every copy of digital data that is legally s...

Spatial variations in composition of marine microbial communities and its causes have largely been disclosed in studies comprising rather large environmental and spatial differences. In the present study, we explored if a moderate but temporally permanent climatic division within a contiguous arctic shelf seafloor was traceable in the diversity patterns of its bacterial and archaeal communities...

This contribution presents sediment classification results derived from different sources of data collected at the Dordtse Kil river, the Netherlands. The first source is a multi-beam echo-sounder (MBES). The second source is measurements taken with a gamma-ray scintillation detector, i.e., the Multi-Element Detection System for Underwater Sediment Activity (Medusa), towed over the sediments an...

Falsifying Global Navigation Satellite System (GNSS) data with a simulator or with a fake receiver can have a significant economic or safety impact in many transportation applications where Position, Velocity and Time (PVT) are used to enforce a regulation. In this context, the authentication of the source of the PVT data (i.e., the GNSS receiver) is a requirement since data faking can become a...

Sediment delivery ratio (SDR) is traditionally defined as the fraction of upland gross erosion that is transported out of a defined area, e.g., a plot or catchment. It is, effectively, an index of sediment transport efficiency. Previously, it is treated as an empirically-lumped parameter used as a mechanism for compensating for sediment deposition within a catchment area. In this paper, we prop...

Indoor positioning has garnered significant interest over the last decade due to rapidly growing demand for location-based services. As a result, multitude of techniques been proposed localize objects and devices in indoor environments. Wireless fingerprinting, which leverages machine learning, emerged as one most popular approaches its low implementation cost. The prevailing fingerprinting-bas...

Two sediment cores were collected from Hailing Bay located in a typical mariculture zone of Guangdong Province, South China, and analyzed for polycyclic aromatic hydrocarbons (PAHs). The concentrations of the sum of 27 PAHs ranged from 62 to 1200 ng g(-1) dry wt, and sediment in the study area was considered to be moderately polluted by PAHs. Source diagnostics based on PAH composition and prin...
