X-ray timing of the accreting millisecond pulsar SAX J1808.4-3658
… a 7 yr timing study of the 2.5 ms X-ray pulsar SAX J1808.4-3658, an X-ray transient with a recurrence time of =2 yr, using data from the Rossi X-ray Timing Explorer covering 4 transient outbursts (1998-2005). Substantial pulse shape variability, both stochastic and systematic, was observed …

Anomaly detection in rolling element bearings via two-dimensional Symbolic Aggregate Approximation
… through Symbolic Aggregate Approximation (SAX) in the two-dimensional time-frequency domain. SAX reduces computational requirements by partitioning high-dimensional sensor data into discrete states. This analysis specifically suits bearing vibration data in the time-frequency domain, as the …

A Genome-wide Association Study of Schizophrenia in the South African Xhosa and Generalizability of Polygenic Risk Score across African populations
… of schizophrenia in the South African Xhosa (SAX) population through genome-wide association study (GWAS) analysis, and to determine if PRS derived from EUR and East Asian (EAS) ancestry populations from the Psychiatric Genomics Consortium (PGC) Schizophrenia Working Group were generalizable …

Application of Time Series Analytics to Assess Performance of Artificial Lift Systems Deployed in Coal Seam Gas (CSG) Wells
… images through Symbolic Aggregate Approximation (SAX). SAX serves as a feature extraction technique that converts time series data into a symbolic representation, which is then translated into performance heatmap images. Petroleum and well surveillance engineers label these SAX-generated …

Synthesis and characterisation of hypercrosslinked polymer microparticles and their functionalised derivatives
… (SCX) resins and strong anion-exchange (SAX) resins. For the SCX resins, satisfactory ion-exchange capacities (IECs) were obtained by treating the polymers with concentrated sulfuric acid as a sulfonating agent. In parallel with this work, SAX resins were prepared by treatment of the …

Music in Site: Integrating elements of site-specificity into composition
… and Tunnel Listen (two clarinets, soprano sax, alto sax, tenor sax, two trumpets, two trombones and tuba) explore a range of approaches to site-specificity and embodiment as compositional devices. The outcome of this research has not only been the creation of these three new works, but also …

The analysis of salt resistant surfactants used in enhanced oil recovery.
… ionization mass spectrometry. Mixedmode C1 8/SAX and C8/SAX columns were used for both liquid chromatography and liquid chromatography-mass spectrometry analyses of NPEOS and OPEOS. NPEOS and alkyl aryl sulphonate surfactant mixtures were separated using a mixed-mode C4/SAX column.. Matrix …

Accretion flows and neutron star heating in low-mass X-ray binaries
… the Swift X-Ray Telescope allowed us to observe SAX J1750.8-2900 in the relatively short-lived transition between outburst and quiescence. We found its X-ray spectrum softens towards lower luminosities, which can either be due to a radiatively-inefficient accretion flow or an increasing …

Advanced applications of Raman spectroscopy and super-resolution imaging of biological and plant materials
… cells with a lab-built saturated excitation (SAX) microscope for subdiffraction imaging. This is the first instance in which these QDs were tested as a luminescent probe for subdiffraction biological imaging with SAX microscopy. The excitation modulation frequency (ω) was demodulated for …

Race and the Modernist Imagination: The Politics of Form, 1900--1940
… limitations in the Dr. Fu-Manchu thrillers of Sax Rohmer, where melodramatic race-wars threaten to end white England's global sovereignty. In Katherine Mansfield and Rebecca West's primitivist narratives, blackness and femininity conjoin to become metropolitan modernity's unsuspected keepers. …

Time series data analytics : clustering-based anomaly detection techniques for quality control in semiconductor manufacturing
… These rely on techniques such as the STL and SAX representations of time series, and provide a visual computation of time series discords. In this thesis, these methods are implemented, and their results are compared. Recommendations are provided as to how to best utilize the outputs of these …

Funktionelle Analyse der IgCAMs in der Nervensystementwicklung von Caenorhabditis elegans
… Bekannte Rezeptoren (UNC-5, UNC-40/DCC, und SAX-3/Robo), die für die axonale Wegfindung wichtig sind, gehören zu den Immunglobulin-Zelladhäsionsmolekülen (IgCAMs). Durch die Analyse des vollständig sequenzierten Genoms von C.elegans konnten die Mitglieder dieser Familie identifiziert werden. …

Stan Getz: Forgotten Bebop Tenor Saxophonist
… revolution, Stan Getz’s contributions as a tenor saxophonist have been underappreciated. In 1951, Getz demonstrated an improvisational vocabulary that was a fusion of his swing era style, inspired by the melodic conception of Lester Young, and the harmonic improvisations of Charlie Parker. The …

Design and acoustic shielding prediction of hybrid wing-body aircraft
… in the Silent Aircraft Initiative, the SAX-40 aircraft concept was further developed into the N+2 HWB aircraft. The design effort resulted in two aircraft configurations: the N2A aircraft with conventional podded engines, and the N2B aircraft with a distributed propulsion system embedded …

“das ungewisse”: the Uncertain Time of Paul Celan’s “Grabschrift für François”
This dissertation is a detailed study of the poem “Grabschrift für François” [Epitaph for François], written by the Holocaust survivor and mid-20th-century German-language poet, Paul Celan. Celan’s poetry is regarded in the scholarship as a site of mourning for the brutalities of the Holocaust, …

Stress-induced remodeling of the caenorhabditis elegans dauer
… effector complex comprising of the L1CAM homolog SAX-7 to control branching. Chapter 4 compares regulation of this complex between stress-induced IL2 branching and FLP branching. Here I find a previously unknown genotype by environment interaction within the UPR, demonstrating …

X-ray spectroscopy of neutron star low-mass X-ray binaries
… from the accretion-powered millisecond pulsar SAX J1808.4-3658 and the Z source XTE J1701-462. Each was observed by the Chandra X-ray Observatory to produce a high-spatial-resolution image. This work was motivated in part by my analysis of XTE J1814-338, which found an apparent excess of …

High pressure liquid chromatography of nucleotides and nucleic acid bases from fungi
… fungal species is accomplished on AS-Pellionex-SAX pellicular anion exchanger using a high pressure liquid chromatograph. Identification of nucleotides was by comparing peak retention times; by differential ultra-violet absorption with two detectors in series at selected wavelengths; and by acid …
