HlGH RESOLUTION PALAEOMAGNETIC ANALYSES OF CRETACEOUS SHALLOW WATER CARBONATES
… From this link it is possible to date the absolute time represented by the sediments, and the absolute time of acquisition of the palaeomagnetic signal. The palaeomagnetic signal is independent of sedimentological characteristics and lithofacies organization. The mean palaeolatitude and the …

Towards a general temporal theory
The research work presented herein addresses time representation and temporal reasoning in the domain of artificial intelligence. A general temporal theory, as an extension of Alien and Hayes', Gallon's and Vilain's theories, is proposed which treats both time intervals and time points on an equal …

Understanding time in natural language text
Understanding time is essential to understanding events in the world. Knowing what has happened, what is happening, and what may happen in the future is critical for reasoning about those events. It is thus an important natural language processing (NLP) task to understand time. This thesis advances …

Fluvial facies, vertebrate taphonomy and palaeosols of the Teekloof formation (Permian) near Beaufort West, Cape Province, South Africa
… on sedimentary processes, palaeohydrology, absolute time represented in the stratigraphic record and the topography, soils and habitats of the ancient landscape. These are summarized into a palaeoenvironmental synthesis of the Teckloof Formation.

Time and process in sedimentary rocks at the dawn of animal life
… studies track change in space and relative time, and radiometric studies allow us to tie events to absolute time. Both are necessary to understand how and if changes in environment are linked to early animal evolution. This thesis combines both. Chapters 1 and 2 of this thesis explore early …

Combining microstructural analysis with EPMA monazite geochronology to constrain progressive stages of orogenesis in the Appalachians
… been obtained using the FIA method, chemical and absolute time data for these interpretations is required. Microstructurally, successive portions of garnet porphyroblasts generally do not correlate with the chemical zoning patterns of major cations, despite these porphyroblasts preserving a …

From order to narrative: assembling eventfulness through Bayesian chronologies. A view from the Early Bronze Age (3500-2500 BCE) South Caucasus
This dissertation addresses the impasse between absolute time and lived temporalities through a radiocarbon-based approach. I harness Bayesian chronological modeling as a theoretical and methodological intervention to reconstitute “eventfulness” from the ground up. Instead of exploring change as …

Robust GPS-based timing for phasor measurement units based on single-receiver and multi-receiver position-information-aided vector tracking
… of the power grid. This technology produces time-stamped voltage and current phasor measurements, allowing measurements from any point in the power infrastructure to be synchronized. Widely regarded as one of the most vital devices in monitoring and control for the future of power systems, …

Reframing Strategic Inertia: The Politics of Innovation and the Case of GM Biotechnology
… of power relations within the synchronization of time and space in social organisations, typically as part of the design and implementation of strategy, in context of organisational definitions of innovation and contestations of 'the new'. With a conceptual archaeology, the thesis contends that …

Stochastic Models For Evolutionary Genetic Problems
… critical to determine the population persistence time; 2) increasing the advantageous mutation rate reduces the extinction risk although its effects are usually shadoby population size and fitness; 3) the new mutation correlation among environments rises during the evolution process, but it has …

A Philosophical Reappraisal of Henry More’s Theory of Divine Space
… and John Lucas—have convincingly argued that absolute space and time remain consistent with a cosmic spacetime as well as with a Neo-Lorentzian interpretation of relativity. Yet while many have allowed this possible return of absolutes to reshape their theology and philosophy of time, few seem …

Mitofusin 2 Regulated Transport of Mitochondria is Necessary for Axonal Integrity
… expression of the MFN2 homologue MFN1, absolute length of axons or absolute time to disease may account for the discrepancy between the mouse model and human patients. Hopefully this work will help elucidate the molecular mechanisms underlying CMT2A and contribute toward a more general …

Time-dependence in Markovian decision processes.

Reconstructing climate from the Dead Sea sediment record using high-resolution micro-facies analyses

Neural Time Alignment for End-to-End Automatic Speech Recognition Systems

Statistical Analysis of Geolocation Fundamentals Using Stochastic Geometry
