Signature Crossroads
Signature Crossroads, an urban form that grows out of an street intersection, combines both the sense of "transit" and the sense of "destination." Such dual character gives Signature Crossroads a superiority over traditional squares as the identity in contemporary cities. This thesis investigates …

Metabolomic Signature of Hypertension
… identified a knowledge gap regarding metabolomic signature of prevalent and incident hypertension. This was addressed by performing a metabolomic analysis of multi-ethnic cohort of Insulin Resistance Atherosclerosis Study. The advanced techniques utilized for sampling, extraction, detection and …

Solid fuel ramjet infrared signature
… ratio (Ø) and fuel composition on the infrared signature of solid fueled ramjets (SFRJ). Solid fuels investigated were Plexiglas, HTPB, and HTPB with aluminum, silicon, boron carbide, and/or magnesium. They were tested at chamber pressures of 80-170 psia and with equivalence ratios between 0.3 …

Magnetic Signature Estimation Using Neural Networks
… and geometry, and is known as the magnetic signature. As a precursor to first principle modeling of the phenomenon and a proof of concept, the goal of this research is to predict offboard magnetic signatures from on-board sensor data using a neural network. This allows magnetic signature …

Compositional models for mutational signature analysis
… even throughout tumour development. Mutational signatures were introduced as a proxy to quantify the number of mutations created by each mutational process. This thesis focuses on statistical methods for the analysis of such mutational signatures. Crucially, mutational signatures, in the type of …

Signature change in spherical vacuum spacetimes
… the approach of papers (1, 2) by exploring signature changes in other metrics. The metrics we chose to investigate are the Schwarzschild metric and the Tolman metric. The Schwarzschild metric was originally chosen in order to investigate whether the neighborhood of the singularity inside a …

Security of Unbalanced Oil-Vinegar Signature Scheme
<p>We explore ideas for oil-vinegar signature schemes in the multivariate polynomialcryptography.</p><p>In the first half, we focus on TTS (Tame Transformation Signature) systems. We find a structure attack to defeat a family of TTS systems. Then we have the related complexity analysis to claim …

Trace-based hardware control flow signature checking
Since the widespread adoption of the internet, computer security has become one of the primary concerns of computer systems engineers, who are often faced with a choice between increased performance and stronger security policies. Many advancements in computer security impose a performance penalty. …

On the signature of the Shapovalov form
… Hermitian form. Finding a formula for the signature of the Shapovalov form is a related problem which may be a necessary first step in such a classification. A Verma module may admit an invariant Hermitian form, which is unique up to multiplication by a real scalar when it exists. Suitably …

An application of signature of smooth manifolds
We prove that no disjoint union of any number of copies of even dimensional complex projective space can bound a smooth oriented compact manifold with boundary. We prove this by defining and computing certain algebraic invariants for smooth oriented manifolds. A non-diffeomorphic relationship is …

Topological Network Alignment Based on Graphlet Degree Signature
… of network alignment based on graphlet degree signatures, called GRAAL, which can be used to align any kind of networks not just biological ones. Several global network alignment algorithms also have been designed based on GRAAL, such as MI-GRAAL, H-GRAAL, and C-GRAAL. However, the alignment of …

Efficient Radiometric Signature Methods for Cognitive Radio Devices
This thesis presents the first comprehensive study and new methods for radiometric fingerprinting of the Cognitive Radio (CR) devices. The scope of the currently available radio identification techniques is limited to a single radio adjustment. Yet, the variable nature of the CR with multiple …

Modelling the induced magnetic signature of naval vessels
… predict and reduce the electromagnetic signature of ships is growing. There are a number of components to the electromagnetic field surrounding a ship, with each component originating from different physical processes. The work presented in this study is concerned with the magnetic …

Signature schemes and applications to cryptographic protocol design
Signature schemes are fundamental cryptographic primitives, useful as a stand-alone application, and as a building block in the design of secure protocols and other cryptographic objects. In this thesis, we study both the uses that signature schemes find in protocols, and the design of signature …
