A Copula-Tensor Neural Network Framework for High-Dimensional Causal Inference

Estimating conditional average treatment effects (CATEs) in high-dimensional causal inference problems remains challenging because complex nonlinear relationships, heterogeneous feature distributions, and dependence among covariates can limit the effectiveness of conventional mac...

Tourist Environmental Awareness and Conservation Engagement in a Caribbean Marine Protected Island System: Evidence from Cozumel, Mexico

Tourism is a major driver of economic growth in tropical island destinations but also places increasing pressure on fragile marine ecosystems. This study examined tourists’ environmental awareness, perceptions, and conservation-related behaviors on Cozumel Island, part of the Mes...

Development of a chemometric platform for mid-infrared fermentation monitoring

<title>Abstract</title> Industrial bioprocess development still depends heavily on off-line analytics such as HPLC, which, while accurate, are slow and limit real-time decision-making. Process Analytical Technologies (PAT) can overcome this barrier, with mid-infrared spectroscopy...

Digital-Twin-Driven Design and Financial Validation of a Collaborative Robotic Cell for Automated Chocolate-Bar Unwrapping in a Small-Scale Confectionery Plant

Manual unwrapping of chocolate bars in a family-owned confectionery in Monterrey, Mexico, is a labor-intensive process that produces inconsistent cycle times, high product damage, and elevated payroll costs. This paper presents the design, discrete-event and kinematic simulation,...

A Multi-Layer Digital Twin Framework for a Confectionery Preparation Cell with AI-Assisted SCADA 4.0 Monitoring

This paper presents a semester-long engineering project that develops a multi-layer Digital Twin for the chocolate-bar preparation stage, a bakery producer in Monterrey, Mexico. In the current process, operators manually open shipping boxes, separate multi-bar packages, peel indi...
