Spectral fingerprinting
… at the catchment scale. Among these, sediment fingerprinting, a technique to trace back the origin of sediment, has attracted increasing attention by the scientific community in recent years. It is a two-step procedure, based on the fundamental assumptions that potential sources of sediment can …

RF Fingerprinting Unmanned Aerial Vehicles
… we propose an authentication system based on RF fingerprinting. Specifically, we extract and use the device-specific hardware impairments embedded in the transmitted RF signal to separate the identity of each UAV. To achieve this goal, AlexNet with the data augmentation technique was employed.</p>

Extensions to Radio Frequency Fingerprinting
Radio frequency fingerprinting, a type of physical layer identification, allows identifying wireless transmitters based on their unique hardware. Every wireless transmitter has slight manufacturing variations and differences due to the layout of components. These are manifested as differences in …

Statistics and algorithms for peptide mass fingerprinting
… and algorithmical aspects of peptide mass fingerprinting (PMF). In a PMF experiment, a purified protein sample is digested by a protease using an enzymatic cleavage reaction, the masses of the resulting peptides are measured by mass spectrometry, yielding the mass fingerprint, and compared …

Ultra-high field (7T) magnetic resonance fingerprinting
… difficult to adapt for 7T. Magnetic Resonance Fingerprinting (MRF) is an alternative model-based technique to quantify multiple tissue properties after a single scan. MRF was initially created for clinical (1.5T and 3T) MRI scanners, where it has been widely applied to map T1, T2 and other …

Hardware and software fingerprinting of mobile devices
… contributions in two challenging areas: library fingerprinting, to identify third-party software libraries, and device fingerprinting, to identify individual hardware components. Our work has significant implications for the privacy and security of mobile platforms. Software-based library …

Application of Polychlorinated Biphenyl Signatures for Environmental Fingerprinting
… of using PCB signatures for environmental fingerprinting is an effective analytical method capable of producing high resolution signatures from biological samples. An extraction and clean-up method was developed that was successfully applied to different biological matrices (blood and …

Characterization and protein fingerprinting of Botrytis cinerea isolates /
Botrytis cinerea isolates collected from Niagara region were treated with different concentrations of the fiingicide, iprodione to test their sensitivity to this fungicide. These Botrytis cinerea isolates were divided into two groups according to their sensitivity to iprodione. Those isolates whose …

A feature-based fingerprinting scheme robust to desynchronization
Traitor-tracing (aka fingerprinting) has received much attention as a possible solution for protecting media copyrights. However, current schemes for image and video fingerprinting lack robustness against geometric attacks. We propose a novel semi-blind fingerprinting scheme that can cope with such …

VM and workload fingerprinting for software defined datacenters
In this work we develop strategies for mining telemetry streams in virtualized clusters to automatically discover relationships between sets of virtual machines. Examples of relationships include correlations between virtual machines, similarities in resource consumption patterns or dominant …

Power Fingerprinting for Integrity Assessment of Embedded Systems
This dissertation introduces Power Fingerprinting (PFP), a novel technique for assessing the execution integrity of embedded devices. A PFP monitor is an external device that captures the dynamic power consumption of a processor using fine-grained measurements at the clock-cycle level and applies …

Multiparametric Estimation of Brain Hemodynamics with MR Fingerprinting ASL
… four minutes. The concept of magnetic resonance fingerprinting (MRF) was incorporated into the framework of ASL technique, and a novel sequence, MRF-ASL, was proposed. It is a promising alternative technique in cerebrovascular patients who cannot receive contrast agent based MRI perfusion. This …

Distributional Fingerprinting of Cell Population Phenotypes and Drug Activities
<p>From gene expression to protein abundance, biological measurements have traditionally been taken as population averages. Studies over the past decade, however, have established the biological relevance of population heterogeneity, even for cells with identical genetic background. The …

Atom-Based Geometrical Fingerprinting of Conformal Two-Dimensional Materials
<p>The shape of two-dimensional materials plays a significant role on their chemical and physical properties. Two-dimensional materials are basic meshes that are formed by mesh points (vertices) given by atomic positions, and connecting lines (edges) between points given by chemical bonds. …

An evaluation of DNA fingerprinting methods for subtyping Salmonella
The use of DNA typing and fingerprinting methods to identify and discriminate strains of bacteria, including Salmonella, has increased dramatically in recent years. Traditional typing methods, including serotyping and phage typing, have often not adequately discriminated strains, nor have they …

Detection- and Information -Theoretic Analysis of Steganography and Fingerprinting
… of perfectly secure steganography and public fingerprinting. For both games, a randomized stacked-binning scheme and a matched maximum penalized mutual information decoder are used to achieve capacity and to realize a random-coding error exponent that is strictly positive at all rates below …

Fingerprinting and characterisation of Escherichia coli isolates using DNA arrays
Two commercially available DNA whole genome Escherichia coli K12 arrays were compared to identify a subset of markers for typing. The arrays were identical in probe composition but different in substrate (membrane and glass slide arrays) and probe preparation (radio- and fluorescent-labelled). …

Understanding and mitigating the privacy risks of smartphone sensor fingerprinting
… everyday life gives rise to privacy concerns. Fingerprinting smartphones can jeopardize user privacy by enabling remote identification of users without users' awareness. In this dissertation we study the feasibility of using on-board sensors such as microphones, accelerometers and gyroscopes to …

Understanding Drivers of Stratospheric Ozone Change and Fingerprinting its Recovery
… In Chapter 6, I applied a pattern-based “fingerprinting” technique to quantitatively separate the contributions of ODS forcing from other external forcings and internal variabilities in satellite observations. This analysis shows that Antarctic ozone increases cannot be explained by …

An Automatic Commercial Search Application for TV Broadcasting Using Audio Fingerprinting
… automatic commercial search scheme using audio fingerprinting and implement it in a PC-based application. Our commercial search algorithm is composed of two parts: one for audio feature extraction and another for database search. For the first part, although the video stream of TV broadcast …
