The framework employs a Random Forest model augmented with a monthly Empirical Cumulative Distribution Function (ECDF) correction. Auxiliary predictors are incorporated to enhance physical interpretability and stability, including terrain attributes to represent orographic effects, land-cover …

Geometric Modeling Through Multiple Implicit Functions, Yiwen Ju

McKelvey School of Engineering Graduate Student Theses & Dissertations

Implicit representations have become a dominant paradigm in computational settings ranging from learning-based geometry generation to advanced manufacturing. While treating geometry as the level set of a black-box function provides significant modeling flexibility, converting these representations into explicit surface meshes remains a major challenge. Standard volumetric extraction methods are fundamentally designed for smooth manifolds and therefore struggle to capture sharp geometric features such as creases, corners, and non-manifold junctions that are critical for high-fidelity industrial design and engineering tasks. Many of these intricate features arise from modeling multiple implicit functions. Examples include Constructive Solid Geometry (CSG), material interfaces, and more …

Black Hole Spectroscopy And Tests Of General Relativity With Gw250114, A. G. Abac, I. Abouelfettouh, Teviet Creighton, Mario C. Diaz, Raul Alberto Espinosa Perez, J. Lawrence, Francisco Llamas Villarreal, Soma Mukherjee, Volker Quetschke, Miriam Ramos Arevalo, Wenhui Wang

Physics & Astronomy Faculty Publications

The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein’s general relativity (GR) in the high-velocity, strong-gravity regime and probe whether the remnant conforms to the Kerr metric. Upon perturbation, black holes emit a spectrum of damped sinusoids with specific, complex frequencies. Our analysis of the postmerger signal shows that at least two quasinormal modes are required to explain the data, with the most damped remaining statistically significant for about one cycle. We probe the remnant’s Kerr nature by constraining the spectroscopic pattern of the dominant quadrupolar (ℓ =𝑚 =2) …

Yield-To-Maturity And The Reinvestment Of Coupon Payments: Reply

Journal of Economics and Finance Education

Our original note addressed a common misconception that to earn the yield-to-maturity (YTM) on a coupon bond an investor must reinvest the coupon payments. Shirvani and Wilbratte (2009) take issue with our presentation and results. We will demonstrate that their arguments entirety rest on the proposition that the YTM must equal the realized compounded yield (RCY). This is a construct that explicitly assumes coupon reinvestment. We made no claim in our original presentation with regard to their proposition, because it is not required to calculate the YTM. Furthermore, we will discuss their claims with regard to the “economic significance” of …

Yield To Maturity Is Always Received As Promised: A Reply

Journal of Economics and Finance Education

This note attempts to further spell out why it is a myth that YTM is viewed as only a promised but not really earned interest rate. It addresses some misconceptions in Shirnani and Wilbratte (2009, this issue) on what, between YTM and RCY, is a true rate of return of a coupon bond, why YTM is NOT just a “fictitious mathematical construct”, and why YTM has nothing to do with yield curve.

The Relationship Between The Promised And Realized Yields To Maturity Revisited

Journal of Economics and Finance Education

This paper reaffirms the long-held view that the promised yield to maturity of a coupon bond can be realized only under certain restrictive conditions. Specifically, the realized yield equals the promised yield only if the spot rate and yield curves are flat and remain unchanged throughout the term of the bond, a condition which rarely if ever holds. In addition, we explain that, regardless of the reinvestment rates, the promised yield on a coupon bond will be realized, provided that the bond is held not to its maturity but to its duration.

Parsimonious Expected Utility And In-The-Large Risk Premiums For The Undergraduate Curriculum

Journal of Economics and Finance Education

Expected utility theory, Pratt and Arrow’s risk premium, and the Markowitz risk premium are based upon Von Neumann and Morgenstern’s five axioms of cardinal utility. The derivation of these measures from these axioms is generally considered too mathematically sophisticated for the undergraduate curriculum. This leaves a wide gap in the foundation of financial theory for the undergraduate. An alternative simplified presentation of expected utility that is suitable for the undergraduate curriculum, and that avoids the nuances and complexities of the traditional mathematically more complete derivation, is presented here. In addition, an easily derived in-the-large risk premium is shown to be …

Time Spent Online And Student Performance In Online Business Courses: A Multinomial Logit Analysis

Journal of Economics and Finance Education

This study examines the determinants of academic achievement in online business courses. As a measure of effort, we use the total amount of time each student spent in the course. We estimate a multinomial logistic model to examine the odds of attaining one grade versus another depending on time spent online, GPA, and some demographic characteristics of students. Our findings suggest that extra effort can help a student move from letter grades F, D and C to grade B, but is less helpful for the move from B to A. For the latter improvement, a high GPA matters the most.
