Evaluation of Land Snails for Clumped Isotope Paleothermometry: A Case Study of the Pleistocene of Bermuda
(2013-06-19)
With the advent of clumped isotope analyses, sources of data that were previously not of use in determining paleoenvironment may become valuable proxies for the reconstruction of past Earth surface temperatures. Land snails, ...
Assessing the role of the San Andreas fault in controlling the spatial distribution of erosion rates in the Transverse Ranges, Southern California
(2013-05-17)
In considering erosion rate controls, previous work has focused primarily on the geomorphic factors; here tectonic controls, particularly seismic shaking, are additionally considered, given the growing recognition that ...
The magma-hydrothermal transition zone on the East Pacific Rise
(2013-06-19)
Seawater circulation in the subsurface of submarine hydrothermal systems has an important role in chemical exchange between seawater and ocean crust. The boundary layer between hydrothermally and magmatically dominated ...
Permian Secular Variation of the Ayaguz formation in Kazakhstan
(2013-05-17)
This study uses 60 individual volcanic flows from the Early Permian in eastern Kazakhstan with the intention of analyzing to what extent secular variation of the geomagnetic field may be reduced during the Kiaman ...
Insights into the Position of Kyrgyzstan in the Silurian
(2013-05-17)
This study examined 101 cores from 16 basaltic flows from the Silurian in northern Kyrgyzstan with the aim of understanding the paleoposition of Kyrgyzstan. This is important as very little is known about the Kazakhstania ...
Conditional Clustering Method on KNN for Big Data
(2024)
This thesis endeavors to address the challenges faced by k-nearest neighbor (KNN) classifiers when handling big data, particularly concerning large storage requirements and extended training times. The proposed solution ...
PAL versus SMC: Two Approaches in Compartmental Modeling
(2024)
Partially Observed Markov Process (POMP) models have been extensively employed in epidemiological modeling over the past several decades to understand disease patterns and inform policy-making. Although the observation ...
A Path Integral Investigation and Numerical Simulation of the Two-Slit Problem in Quantum Mechanics
(2024)
In this paper we describe a complete numerical treatment of the two-slit experiment for quantum mechanics. We first introduce the two-slit problem and the Fraunhofer approximation. We describe a number of experimental ...
Model Based Inference of Stochastic Volatility via Iterated Filtering
(2024)
The Heston stochastic volatility model is one of the most widely studied stochastic volatility models, in which the variance follows a Cox–Ingersoll–Ross process. Estimating this model under the physical measure is ...
Large N, Small T, Multiple P: A Causal Matrix Completion Method for CRM Panel Data
(2024)
The prototypical customer relationship management (CRM) panel structure is composed of many customers (large N), with short histories (small T), and multiple outcome metrics (multiple P). Our paper aims to tackle the ...
