Enhanced Prediction Of Condensation Pressure Drop In Mini And Microchannels Using Physics-Assisted Machine Learning, Farshad Barghi Golezani, Jiayuan Li, Forouzan Naderi, Alexander Meylikhov, Logan M. Pirnstill, Issam Mudawar, Chirag R. Kharangate

Faculty Scholarship

Reliable prediction of frictional pressure drop during condensation in mini‑ and microchannels underpins both thermal management effectiveness and overall heat transfer performance in compact two‑phase heat exchangers, cold‑plates, and on‑chip cooling loops. Excess pressure loss burdens pumps, raises electrical consumption, and can destabilize flow, whereas under‑prediction risks temperature overshoot and premature dryout. Conventional empirical correlations and flexible machine-learning models can lose accuracy once channel size, working fluid, or operating conditions stray beyond their testing range. This study uses a physics‑assisted machine‑learning framework that overlays an XGBoost residual learner on the Kim–Mudawar separated‑flow correlation to achieve high fidelity and robustness in …

Edge Percolation Centrality: A New Measure To Quantify The Influence Of Edges During Percolation In Networks, Christina Durón, Hannah Kravitz, Moysey Brio

Mathematics and Statistics Faculty Publications and Presentations

Numerous centrality measures exist to quantify the influence of edges within a network, with edge betweenness being one of the more well-known measures. However, such measures are inadequate in network percolation scenarios (e.g., the transmission of a disease over a transportation network of highways) as they fail to consider the changing percolation states of edges over time. This paper addresses this limitation by extending percolation centrality, a measure originally developed to evaluate the influence of vertices during a percolation process (i.e., a dynamic spread of a contagion) in the network, to the edge level. The proposed measure, edge percolation centrality, …

Observing The Dynamics: Black Labour And Cultural Taxation, Kay Coates

University Libraries: Faculty Presentations

Associatively, the Dynamic Social Impact theory (DSIT) can effectively demonstrate the convergence of labor, culture and service in connection with Black labor and cultural taxation within the productivity sector. One of the four patterns identified in DSIT indicates that minority groups within a larger culture can be found to be both isolated and vibrant. This isolation allows minority influence to persist. To such an extent that certain marginalized, underrepresented people in the productivity field often face underlying stressors that disproportionately affect their health and overall well-being. This lightning round presentation takes an appreciative enquiry perspective to promote the development of …

All Decisions

In this nonprimary residence holdover proceeding, the landlord moved to restore the case for immediate trial five years after it was marked off calendar for discovery. The court denied the motion, finding the landlord failed to demonstrate a reasonable excuse for the lengthy delay, a lack of prejudice to the tenant, or to address the merits of the underlying nonprimary residence claim. Citing Appellate Term precedent, the court emphasized that a motion to restore, filed more than one year after a case is stricken, requires proof of merit, lack of prejudice, lack of intent to abandon, and a reasonable excuse …

Probabilistic Intervals Around Population Forecasts: A New Approach With A Subnational Example Using Washington State Counties, David A. Swanson, Jeff Tayman

Publications, Reports and Presentations

Population forecasts produced by governments at all levels are used in the public sector, the private sector, and by researchers. They have been primarily produced using deterministic methods. This paper shows how a method for producing measures of uncertainty can be applied to existing subnational population forecasts while meeting several important criteria, including the concept of utility. The paper includes an assessment of the efficacy of the method by: (1) examining the change in uncertainty intervals it produces by population size and population growth rate; and (2) comparing the width and temporal change of the uncertainty intervals it produces to …

We deal with Green’s functions (Green’s-f ) for 2-nd order dynamic boundary value problems (BV-P’s) on T. Green’s function is established on T for different situations to solve constructed problems. These results show how important Green’s-f is for mathematical physics on T.

A Combined Dld-Inar(P) Model For Overdispersed Count Data, Norbert Zongo University, Koudougou, Burkina Faso, Tegawende Martin Kabore, O. Jean-Etienne Ouedraogo

Baku Mathematical Journal

In this paper, we develop a combined order p integer-valued autoregressive process whose marginal distribution follows the discrete Lindley distribution (DLD) [1]. Referred to as the CDLD-INAR(p) process, this model is particularly suited for modeling count time series exhibiting overdispersion. Formulation of this model is based on the binomial thinning operator introduced by Steutel [8]. Several conditional theoretical properties of the process are established, and its parameters are estimated using the conditional maximum likelihood method. The asymptotic properties of the resulting estimators are also investigated. Finally, the practical relevance of the proposed model is demonstrated through an application to real …

Wavelet-Based Estimation Of Long-Memory Parameter In Stochastic Volatility Models Using A Robust Log-Periodogram, University Of Kara, Kara, Togo, Manganaw Ndaam, Tchilabalo Abozou Kpanzou, Edoh Katchekpele

Baku Mathematical Journal

In this paper, we propose a novel method for estimating the long-memory parameter in time series. By combining the multi-resolution framework of wavelets with the robustness of the least absolute deviations criterion, we introduce a periodogram providing a robust alternative to classical methods in the presence of non-Gaussian noise. Incorporating this periodogram into a log-periodogram regression, we develop a new estimator. Simulation studies demonstrate that our estimator outperforms the Geweke and PorterHudak (GPH) and wavelet-based log-periodogram (WBLP) estimators, particularly in terms of mean squared error, across various sample sizes and parameter configurations.

On One Problem Of Feedback Control Of A Heating System, Azerbaijan State Oil And Industry University, Baku, Azerbaijan, Vagif Abdullayev

Baku Mathematical Journal

We consider a problem of controlling a heating device intended for heating a coolant supplying heat to a closed system is considered. Feedback is used to control the process, in which information about the process state is continuously or discretely received from individual points of the device, where temperature sensors are installed. The mathematical model of the controlled process in both cases is described by a point-loaded first-order hyperbolic equation. Formulas for the gradient of the objective functional of the problem are obtained, allowing the use of first-order numerical optimization methods for solving problems. Numerical experiments are carried out using …

On B−Repdigits Which Are Sums Of Three Narayana Numbers With A Consequence, University Of Kara, Kara, Togo, Pagdame Tiebekabe, S´Emou Diouf Cheikh, Anta Diop University, Dakar, Senegal, Salifou Nikiema, L´Ed´Ea Bernard Ou´Edraogo University (Ulbo), Somiaga, Burkina Faso

Baku Mathematical Journal

The sequence known as Narayana’s cows sequence is defined by the thirdorder linear recurrence relation Nn = Nn−1 + Nn−3, for n ≥ 3, with the initial values given by N0 = N1 = N2 = 1. In this paper, we explore the class of numbers known as brepdigits that can be represented as the sum of three terms from this sequence. Specifically, we aim to identify all such numbers for bases in the range 2 ≤ b ≤ 30. Our approach relies on precise lower bounds for linear forms in logarithms, along with an enhanced version of the Baker-Davenport …
