Numerical Study Using Narx To Improve Pipe Vibration In Dosing Pump Systems, Shmoos Rahem Mazal, Mohammed Jawad Mohammed, Mahmoud Mustafa Mahdi

Engineering and Technology Journal

Pressure pulsation is a serious problem in the piping system. It is generated at the beginning and end of the water-pumping process, or when valves suddenly close. The high turbulence of fluid particles in the presence of pressure waves causes multiple stresses on the pipe walls, requiring maintenance and eventual replacement over time. In this research, an experimental setup for a piping system vibration model induced by pulsating pressure is designed, developed, and fabricated. The objective of the present work is to create a MATLAB program using the NARX method at the beginning of the Neural Network time series. Nonlinear …

We first assess the accuracy of its dihedral angle distributions by comparing them to established Ramachandran space and verifying expected behaviors of residues such as glycine and proline. We then use PDBMine to …

The Six-Course Guitar In Spain: Some Considerations Of Repertoire And Musical Practice, Thomas Schmitt

Soundboard Scholar

The six-course guitar is still a little-known instrument. One need only look at books on the history of music to verify that claim: there is hardly any mention of it, nor are its composers or repertoire often cited. In fact, researchers have given far more attention to other plucked-string instruments than to the six-course guitar—whether for reasons of tradition or ideology—leading to a major gap in the literature. The repertoire of the Spanish Golden Age, to take one example, has been thoroughly explored, in the domains of both vocal and instrumental music (as in the vihuela). Similarly, there is quite …

Velez, Otavio Augusto Chaves, Carlos Serpa, Fatma M. Salem, Bibo Li Ph.D., Bin Su Ph.D., Celio Geraldo Freire-De-Lima, Debra Decote-Ricardo, Marco Edilson Freire De Lima

Biological, Geological, and Environmental Faculty Publications

Effective and safe treatments for neglected tropical diseases caused by parasites, such as Chagas disease and sleeping sickness, remain lacking, posing a significant challenge for researchers worldwide. The rational design of dimeric compounds inspired solely by the pharmacophoric core of benznidazole (2-nitroimidazole) has proven to be a promising strategy for antiparasitic development. Thus, in the present work, it was increased the linker between the active units (2-nitroimidazole) to improve the interaction with TcNTR, facilitating the bioactivation of the longest dimers. Biological assays confirmed this, demonstrating that all compounds were active against replicative intracellular amastigotes of Trypanosoma cruzi (Tulahuen C2C4-LacZ). Notably, …

Investigating Age-Related Decline In Sensorimotor Control Using Robotic Tasks, Laura Alvarez-Hidalgo, Ellie Edlmann, Gunnar Schmidtmann, Ian S. Howard

School of Health Professions

Aging is associated with changes in sensorimotor control that contribute to functional decline, mobility limitations, and increased fall risk. Traditional motor assessments often rely on subjective measures, highlighting the need for objective, quantitative tools. We developed three robot-based tasks using the vBOT planar manipulandum to evaluate sensorimotor performance in healthy young (<35 years) and older (>60 years) adults. These tasks uniquely combined bimanual control and altered dynamic conditions to assess age-related differences. The first task required bimanual coordination to control a virtual 2D arm over 400 center-out and return trials, targeting de novo motor learning. The second task involved unimanual reaching with the …

Optimal Quantization Of Finite Uniform Data On The Sphere, Mrinal Kanti Roychowdhury

School of Mathematical & Statistical Sciences Faculty Publications

This paper develops a systematic and geometric theory of optimal quantization on the unit sphere 𝕊2, focusing on finite uniform probability distributions supported on the spherical surface—rather than on lower-dimensional geodesic subsets such as circles or arcs. We first establish the existence of optimal sets of n-means and characterize them through centroidal spherical Voronoi tessellations. Three fundamental structural results are obtained. First, a cluster-purity theorem shows that when the support consists of well-separated components, each optimal Voronoi region remains confined to a single component. Second, a ring allocation (discrete water-filling) theorem provides an explicit rule describing how optimal representatives are …

The Phyrfly Opus: A Unified Standard For Hyperdimensional Time Vectors, Spectrally Isolated Coordination, Neural Hierarchies, And Distributed Proprioception, Steven Kirkland

Defensive Publications Series

This monograph establishes 264 prior art claims for a decentralized, connectionless timing and positioning architecture comprising the UTLP, RFIP, and SMSP protocol triad. It formalizes the PHYRFLY nomenclature to distinguish low-level, hardware-scheduled Physical-Layer synchronization primitives from higher-level application orchestration. The core novelty centers on a Vector Time Representation, encoding temporal state as 8 phase values (ticks modulo coprime integers 211–251) transmitted in 8 bytes, then expanded locally into ~10,000-dimensional hyperdimensional chord vectors for similarity computation and drift estimation. This cyclic encoding enables automatic phase-lock convergence within 5–10 beacon exchanges regardless of initial offset, with the Chinese Remainder Theorem guaranteeing unique …

Existence Of Traveling Waves Of Lotka Volterra Type Models With Delayed Diffusion Term And Partial Quasimonotonicity, William Barker

Faculty Scholarship

This paper investigates the existence of traveling wave solutions for diffusive two-species Lotka–Volterra systems with delays in both the reaction and diffusion terms under partial monotonicity assumptions. The model incorporates small-memory effects in the homo- geneous diffusion term, representing a modification of the random-walk interpretation underlying Fick’s law. We extend the partial (cross) monotone iteration method to systems satisfying a partial quasi-monotone condition through the construction of appropriate upper and lower solutions. Convergence of the iteration is established using Schauder’s fixed point theorem.
