Determining the Particle Size of Pulverized Coal From Spectral Reflectivity Measurements

Journal of Spectroscopy, Volume 2026, Issue 1, 2026.
Pulverized coal is widely used in industrial energy supplies and chemical production. Its combustion efficiency and reactivity are closely related to its particle size distribution. Therefore, precise, fast, and reliable measurement methods are required to determine the particle size of pulverized coal.

Incremental and Parallel Machine Learning Algorithms With Automated Learning Rate Adjustments

Frontiers in Robotics and AI, 2019
The existing machine learning algorithms for minimizing the convex function over a closed convex set suffer from slow convergence because their learning rates must be determined before running them.

Drayage Routing Problems: A Comprehensive Survey and a New Compact Model

Australian &New Zealand Journal of Statistics, Volume 67, Issue 4, Page 491-526, December 2025.
ABSTRACT Drayage involves short‐distance container trucking, a crucial part of intermodal transportation that fills the gap between long‐haul transportation modes and inland facilities. Because of its high costs, drayage has been increasingly drawing the attention of researchers and practitioners from different disciplines, who have been exploring ...

Learning in random utility models via online decision problems

International Journal of Economic Theory, Volume 21, Issue 4, Page 494-526, December 2025.
Abstract This paper examines the Random Utility Model (RUM) in repeated stochastic choice settings where decision‐makers lack full information about payoffs. We propose a gradient‐based learning algorithm that embeds RUM into an online decision‐making framework.

Robust design of flexible supply chains with mobile and modular facilities

AIChE Journal, Volume 71, Issue 11, November 2025.
Abstract Modular manufacturing is increasingly being adopted by the chemical industry in applications where resource availability and product demand are highly distributed and uncertain. Modular plants are often built such that they can be easily relocated.

The Conjugate Function of a Fuzzy $n$-cell Number-Valued Function [PDF]

Sahand Communications in Mathematical Analysis
We introduce the concepts of conjugate and biconjugate fuzzy functions. Utilizing these definitions, we present conjugate calculus rules. In addition, we formulate and demonstrate relevant theorems, including the relationship between the notions of ...

Simultaneous Feature Selection for Optimal Dynamic Treatment Regimens

Statistics in Medicine, Volume 44, Issue 15-17, July 2025.
ABSTRACT Dynamic treatment regimens (DTRs), where treatment decisions are tailored to individual patient's characteristics and evolving health status over multiple stages, have gained increasing interest in the modern era of precision medicine. Identifying important features that drive these decisions over stages not only leads to parsimonious DTRs for

Tropical analysis: With an application to indivisible goods

Theoretical Economics, Volume 20, Issue 3, Page 815-829, July 2025.
We establish the subgradient theorem for monotone correspondences: a monotone correspondence is equal to the subdifferential of a potential if and only if it is conservative, i.e., its integral along a closed path vanishes irrespective of the selection from the correspondence along the path.
