Rate-Of-Penetration (Rop) Prediction Model Based On Formation Characteristics Of Extremely Thick Plastic Mudstone In South China Sea, Zeng Xiaolong, Li Qian, Wei Hongchao, Chen Jiahao, Zhu Haiyan

Coal Geology & Exploration

In terms of petroleum and gas resources, South China Sea is the important energy replacement area in China. However, most of the reservoirs are buried deep, and the strong plasticity of the formation under high confining pressure and the complex geological environment seriously affect the drilling efficiency. It is also very difficult to accurately predict the ROP. Hence, a set of intelligent ROP prediction model was established for the extremely thick mudstone formation with unique viscoelastic and strong plastic characteristics in South China Sea. The model took the actual data of 10 wells in an area of South China Sea …

A Typology Of Illustration, Jeffrey Strayer

Contemporary Aesthetics (Journal Archive)

This article introduces the notions of technique-based, problem-based, and history-based illustrations as kinds of illustration relevant to art and philosophy that are intended to complement those recognized by Wartenberg. In doing so, it considers the possible illustration of different ideas within a single work, and the possibility that the complex interrelation of certain ideas may require a number of works for the success of their illustration. These different possibilities raise the issue of how illustration is related to artistic intention and understanding and to the history of art, with its settled and novel kinds of artistic production. Art as philosophy …

Further Reflections On Visual Illustrations Of Philosophy: A Response To Freeland, Schellekens, And Strayer, Thomas E. Wartenberg

Contemporary Aesthetics (Journal Archive)

The incisive commentaries about Thoughtful Images by Cynthia Freeland, Elisabeth Schellekens, and Jeff Strayer provide the occasion for a rethinking of some of the fundamental claims about visual illustrations of philosophy that I made in the book. The essay begins with a discussion of the “logic” of the term ‘illustration’ and then discusses the relationship between illustrations and technology. A variety of different themes are then addressed, such as the possibility of musical illustrations of philosophy; differences in the processing of written texts and visual images; additions to fidelity and felicity as norms applying to successful illustrations of philosophy; and …

Optimization Of Biomedical Imaging Filters For Use In Recaptured Identity Document Classification, John Magee, Stephen Sheridan Phd, Christina Thorpe Phd

Conference papers

As banks and online financial institutions move toward full remote onboarding services, the attack vectors for bad actors increases to include those of recaptured identity documents. This type of fraud opens banking customers to potential crimes of identity theft, as well as causing reputational damage to the institutions involved. In this paper we extend existing research focusing on the use of biomedical imaging filters and their usefulness when classifying recaptured identity documents. We perform a grid search and demonstrate that different filter configurations exist that dramatically reduce the classification error rates compared to those achieved using only the default filter …

Towards A Virtual Reality Visualization Of Hand-Object Interactions To Support Remote Physical Therapy, Trudi Di Qi, Louanne Boyd, Scott Fitzpatrick, Meghna Raswan, Franceli L. Cibrian

Engineering Faculty Articles and Research

Improving object manipulation skills through hand-object interaction exercises is crucial for rehabilitation. Despite limited healthcare resources, physical therapists propose remote exercise routines followed up by remote monitoring. However, remote motor skills assessment remains challenging due to the lack of effective motion visualizations. Therefore, exploring innovative ways of visualization is crucial, and virtual reality (VR) has shown the potential to address this limitation. However, it is unclear how VR visualization can represent understandable hand-object interactions. To address this gap, in this paper, we present VRMoVi, a VR visualization system that incorporates multiple levels of 3D visualization layers to depict movements. In …

Disentangling Trend Risk And Basis Risk With Functional Time Series, Yanxin Liu, Johnny Siu-Hang Li

Department of Finance: Faculty Publications

In recent multi-population stochastic mortality models, one critical scientific issue is the vague distinction between trend risk and population basis risk. In particular, the cross- and auto-correlations between the innovations of the latent factors representing the common trend and the population-specific trends are often assumed to be non-existent, although they are possibly statistically significant. While it is theoretically possible to capture such correlations by treating the latent factors as a vector time series, the resulting model would contain a large number of parameters, which may in turn lead to robustness problems. In this paper, we address these issues by the …

Lattice Investigations Of The Chimera Baryon Spectrum In The Sp(4) Gauge Theory, Ed Bennett, Deog Ki Hong, Ho Hsiao, Jong-Wan Lee, C. -J. David Lin, Biagio Lucini, Maurizio Piai, Davide Vadacchino

School of Engineering, Computing and Mathematics

We report the results of lattice numerical studies of the Sp(4) gauge theory coupled to fermions (hyperquarks) transforming in the fundamental and two-index antisymmetric representations of the gauge group. This strongly-coupled theory is the minimal candidate for the ultraviolet completion of composite Higgs models that facilitate the mechanism of partial compositeness for generating the top-quark mass. We measure the spectrum of the low-lying, half-integer spin, bound states composed of two fundamental and one antisymmetric hyperquarks, dubbed chimera baryons, in the quenched approximation. In this first systematic, non-perturbative study, we focus on the three lightest parity-even chimera-baryon states, in analogy with …
