Dynamic Factor Analysis of Price Movements in the Philippine Stock Exchange
Brian Godwin Lim, Dominic Dayta, Benedict Ryan Tiu +3
The intricate dynamics of stock markets have led to extensive research on models that are able to effectively explain their inherent complexities. This study leverages the economet…
Bias Attribution in Filipino Language Models: Extending a Bias Interpretability Metric for Application on Agglutinative Languages
Lance Calvin Lim Gamboa, Yue Feng, Mark Lee
Emerging research on bias attribution and interpretability have revealed how tokens contribute to biased behavior in language models processing English texts. We build on this line…
Cybersecurity Study Programs: What's in a Name?
Jan Vykopal, Valdemar Švábenský, Michael Tuscano Lopez +1
Improving cybersecurity education has become a priority for many countries and organizations worldwide. Computing societies and professional associations have recognized cybersecur…
Hydrogen atom as a nonlinear oscillator under circularly polarized light: epicyclical electron orbits
Quirino Sugon, Clint Dominic G. Bennett, Daniel J. McNamara
We used Clifford algebra to find the 2D orbit of a hydrogen electron under a Coulomb force and a perturbing circularly polarized electric field of light at angular frequ…
Formulation of causality-preserving quantum time of arrival theory
Denny Lane B. Sombillo, Neris I. Sombillo
We revisit the quantum correction to the classical time of arrival to address the unphysical instantaneous arrival in the limit of zero initial momentum. In this study, we show tha…
Impact of Automatic Image Classification and Blind Deconvolution in Improving Text Detection Performance of the CRAFT Algorithm
Clarisa V. Albarillo, Proceso L. Fernandez
Text detection in natural scenes has been a significant and active research subject in computer vision and document analysis because of its wide range of applications as evidenced…
Non-crystallographic tail-triangle C-groups of rank 4 and interlacing number 2
Mark L. Loyola, Nonie Elvin S. Leyrita, Ma. Louise Antonette N. De Las Penas
This work applies the modular reduction technique to the Coxeter group of rank 4 having a star diagram with labels 5, 3, and . As moduli, we use the pri…
A Numerical Approach to Pricing Exchange Options under Stochastic Volatility and Jump-Diffusion Dynamics
Len Patrick Dominic M. Garces, Gerald H. L. Cheang
We consider a method of lines (MOL) approach to determine prices of European and American exchange options when underlying asset prices are modelled with stochastic volatility and…
Representation of Exchange Option Prices under Stochastic Volatility Jump-Diffusion Dynamics
Gerald H. L. Cheang, Len Patrick Dominic M. Garces
In this article, we provide representations of European and American exchange option prices under stochastic volatility jump-diffusion (SVJD) dynamics following models by Merton (1…
Intelligent Sensors and Monitoring System for Low-cost Phototherapy Light for Jaundice Treatment
Paul M. Cabacungan, Carlos M. Oppus, Jeremie E. De Guzman +3
A prototype of a low-cost phototherapy light system (LPLS) was deployed by the Ateneo Innovation Center (AIC) at a public hospital in Metro Manila, Philippines. It underwent clinic…
Efficient Sampling for Selecting Important Nodes in Random Network
Haidong Li, Xiaoyun Xu, Yijie Peng +1
We consider the problem of selecting important nodes in a random network, where the nodes connect to each other randomly with certain transition probabilities. The node importance…
Characterization of Completely -Magic Regular Graphs
Arnold A. Eniego, I. J. L. Garces
Let and , where . A graph is said to be -sum -magic if there is a labeling $\ell:E(G) \rightar…
Spacetime Quanta? : The Discrete Spectrum of a Quantum Spacetime Four-Volume Operator in Unimodular Loop Quantum Cosmology
Joseph Bunao
This study considers the operator corresponding to the classical spacetime four-volume (on-shell) of a finite patch of spacetime in the context of Unimodular…
Substitution tilings with dense tile orientations and n-fold rotational symmetry
Dirk Frettlöh, April L. D. Say-awen, M. L. A. N. de las Peñas
It is shown that there are primitive substitution tilings with dense tile orientations invariant under n-fold rotation for n=2,3,4,5,6,8. The proof for dense tile orientations uses…
Hadamard Product Decomposition and Mutually Exclusive Matrices on Network Structure and Utilization
Michael Ybañez, Kardi Teknomo, Proceso Fernandez
Graphs are very important mathematical structures used in many applications, one of which is transportation science. When dealing with transportation networks, one deals not only w…
Pedestrian Static Trajectory Analysis of a Hypermarket
Kardi Teknomo, Gloria P. Gerilla
In this paper, we propose a combination of pedestrian data collection and analysis and modeling that may yield higher competitive advantage in the business environment. The data co…
Skew ray tracing in a step-index optical fiber using Geometric Algebra
Angeleene Ang, Quirino M. Sugon, Daniel J. McNamara
We used Geometric Algebra to compute the paths of skew rays in a cylindrical, step-index multimode optical fiber. To do this, we used the vector addition form for the law of propag…
Simulated effects of site salinity and inundation on long-term growth trajectory and carbon sequestration in monospecific plantation in the Philippines
Drandreb Earl Juanico, Severino Salmo
A mathematical model of coastal forest growth is proposed to describe and test the effects of salinity and inundation in the long-term growth performance and carbon sequestration o…
Topology of the Random Fibonacci Tiling Space
Franz Gähler, Eden Provido
We look at the topology of the tiling space of locally random Fibonacci substitution, which is defined as a-->ba with probability p, a-->ab with probability 1-p and b-->a for 0<p<1…
O(N) algorithms for disordered systems
Vincent E. Sacksteder
The past thirteen years have seen the development of many algorithms for approximating matrix functions in O(N) time, where N is the basis size. These O(N) algorithms rely on assum…
