Computation of the one-dimensional unwrapped phase
In this thesis, the computation of the unwrapped phase of the discrete-time Fourier transform (DTFT) of a one-dimensional finite-length signal is explored. The phase of the DTFT is not unique, and may contain integer multiple of 27r discontinuities. The unwrapped phase is the instance of the phase …

Investments unwrapped : demystifying and automating technical analysis and hedge-fund strategies
In this thesis we use nonlinear and linear estimation techniques to model two common investment strategies: hedge funds and technical analysis. Our models provide transparent and low-cost alternatives to these two nontransparent, and in some cases prohibitively costly, financial approaches. In the …

Real-Time Detection of GPS Spoofing Attack with Hankel Matrix and Unwrapped Phase Angle Data
Cyber-attack on synchrophasor data has become a widely explored area. However, GPS-spoofing and FDIA attacks require different responsive actions. State-estimation based attack detection method works similar way for both types of attacks. It implies that using state-estimation based detection alone …

Manufacture and rehabilitation of guardrail posts using composite fabrics
… fabric-wrapping machine for field applications.;Unwrapped and GFRP wrapped posts were tested for flexural properties. The experimental data were compared with published values. Unwrapped and GFRP wrapped posts were tested under dynamic loads to determine their natural frequencies. Free vibration …

Convection from laser-scanned ice roughness at multiple accretion vent times.
… for this study were created from geometrically unwrapped laser scans of ice accretions to form a flat plate representation of the airfoil surface roughness.

Indoor Localisation System and Methods using Passive UHF RFID with A Mobile Platform
… signal strength indicator (RSSI) and the unwrapped phase profile. After measuring the phase and RSSI, a valid dataset can be obtained by analysing the received RSSI, the strength of which can indicate whether the signal is stable or not. The stationary point of the unwrapped phase profile …

Behaviour of Fibre Reinforced Polymer Confined Reinforced Concrete Columns Under Fire Condition
… model was developed to simulate the behaviour of unwrapped reinforced concrete and FRP strengthened reinforced concrete square or rectangular columns in fire. After validating the numerical model against test data available in literature, it was determined that the numerical model can be used to …

Diffusive Acoustic Confocal Imaging System (DACI): a novel method for prostate cancer diagnosis
… of sound variation was estimated from the 1D unwrapped phase distribution indicating where the phase discontinuities existed. The measurements were conducted in a water aquarium using the tissue-mimicking prostate phantom. Two-dimensional projected images of the amplitude and the phase …

Channel Estimation in Single -Carrier and Multi-Carrier Communication Systems
… the channel. The RMD exploits constraints on the unwrapped phase of FIR systems and results in significant reductions in numerical complexity over existing methods.

Analytic Solutions for Flows Through Cascades
… to facilitate exact solutions, the turbine is unwrapped onto the two-dimensional plane, resulting in a periodic array of blades commonly referred to as a “cascade”. Previous research has been restricted to the case where the cascade consists of a single impermeable row of flat plates at zero …

Analysis of interferometric SAR for topographic mapping
… this case the basic measurements include range, unwrapped phase, and the ground coordinates of control points. The purpose of the least squares adjustment is to determine the most probable solution for the ground coordinates of points identified in the image. The algorithm has been tested with a …

The Emergence of the Bird in Andean Paracas Art. c. 900 BCE - 200 CE
… of this culture and its unique art forms. When unwrapped, mummy bundles of elite males revealed multiple layers of finely woven and elaborately embroidered textiles and painted ceramics, along with gold objects, feathers, and other finely crafted artifacts. Such items indicate that the …

Optimization of surgical supply inventory and kitting
… them off site. These large packs contain unwrapped surgical items (drapes, gown, sutures, etc.) delivered to each operating room prior to the start of surgery. Once a surgical pack is opened, the items inside are consumed or wasted. MGH uses the custom packs to reduce the amount of time …

Ontologies and knowledges of autonomous resistances in Barcelona: An ethnographic analysis of Can Batlló
… narrates and analyses how the proposed theory is unwrapped in the field. In doing so, I analyse my participation with and from within one of those collectives, Can Batlló and, more specifically, a project named La Fondona. Can Batlló is an autonomous and self-organised social centre in the …

Analytical and numerical techniques for wave scattering
… parallel mean flow. This geometry serves as an unwrapped model of the fan components in turbo-machinery. Our contributions include a novel semi-analytical solution based on the Wiener–Hopf technique that extends previous work by lifting the restriction that adjacent blades overlap, and a …

Genome-wide Footprinting Uncovers Epigenetic Regulatory Paradigms by Revealing the Chromatin Occupancy Landscape
… times can capture nucleosomes partially unwrapped or complexed with chromatin remodelers. Stereotypical DNA-binding footprints are evident across all promoters, even at low-transcribed and silent genes. By aggregating the chromatin profiles across transcription-factor--binding sites, we …

Quantification of Dynamic Epithelial Sheet Architecture in Botryllus Schlosseri Using 2-D & 3-D Image Analysis
… high-resolution confocal scans to generate an `unwrapped' 2-dimensional map of the cylindrical blood vessels, on which we performed quantitative analysis of epithelial morphology. In normal vessels, we found the cells to be planar polarized with curvature - dependent axial elongation of cells, …

Optimal spectral reconstructions from deterministic and stochastic sampling geometries using compressive sensing and spectral statistical models
… variogram models. The transformed magnitude and unwrapped phase spectra result in unique statistical models that are optimal over individual frequency blocks, which produce accurate spectral reconstructions that account for localized variability in the spectral domain. The Kriging spectral …
