Item type:Publication, Deep Learning Automated Measurements of Expanded Polystyrene Beads Size Using Low‐Resolution Micrography<jats:title>ABSTRACT</jats:title><jats:p>The analysis of microscopic characteristics of closed‐cell polymeric foams, particularly bead size, is relevant for understanding properties such as thermal insulation, energy absorption, and compressive structural strength of these materials. This study presents an automated method based on Deep Learning models to measure the bead size of Expanded Polystyrene foams in low‐resolution micrographs. The results of this approach were compared with manual measurements at two expanded polystyrene foam densities: 8.5 and 24 kg/m<jats:sup>3</jats:sup>. Hypothesis tests, including Student's <jats:italic>t</jats:italic>‐test, Levene's test, and Mann–Whitney <jats:italic>U</jats:italic> test, were conducted and showed no significant differences between manual and automatic measurements. Student's <jats:italic>t</jats:italic>‐test and Levene's test indicated that both methods have comparable means and variances, while the Two One‐Sided Test confirmed that they were equivalent for bead size measurement. Additionally, the Mann–Whitney <jats:italic>U</jats:italic> test revealed no differences in medians, and Bland–Altman plot analyses demonstrated no systematic bias between the methods. Taken together, these results suggest that the proposed Deep Learning‐based method is a reliable and precise substitute for the manual method in measuring the bead size of expanded polystyrene, making it suitable for practical use in the bead microstructural analysis of expanded polystyrene material.</jats:p>36 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Stability-Aware Security–Performance Trade-Off Analysis in Resource-Constrained IoT Systems: A Time-Series and Bootstrap-Based Evaluation of TLS and Hybrid ECC–AES Mechanisms(MDPI AG, 2026-05-02); ;Alvarez-Garcia, Maria Fernanda; ;Visconti, PaoloThe increasing deployment of resource-constrained Internet of Things (IoT) devices requires security mechanisms that preserve confidentiality without compromising energy efficiency or responsiveness. Although Transport Layer Security (TLS) provides standardized protection for MQTT-based communication, its computational overhead may significantly affect embedded architectures. This study presents a controlled experimental evaluation of three communication configurations implemented on ESP32-based nodes: unencrypted Message Queuing Telemetry Transport (MQTT), MQTT over TLS 1.2, and an application-layer hybrid scheme combining Elliptic Curve Diffie–Hellman key exchange with AES-128 encryption. Second-level measurements of instantaneous current, accumulated energy, end-to-end latency, and memory footprint were collected across repeated experimental runs. Time-series diagnostics were performed to assess autocorrelation and stationarity, and block bootstrap resampling was applied to ensure dependence-aware statistical inference. The results indicate that TLS introduces the highest cumulative energy growth and latency dispersion, while the hybrid ECC–AES configuration demonstrates intermediate behavior with reduced overhead relative to TLS. Pareto frontier analysis shows that TLS is dominated in the joint energy–latency space, whereas the hybrid scheme represents a non-dominated compromise between security and efficiency. These findings provide a stability-aware and statistically robust framework for evaluating security–performance trade-offs in embedded IoT systems.31 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Automating BIM Change Certification with Blockchain: A Case Study in Residential Building Design(International Association for Automation and Robotics in Construction (IAARC), 2026-06-22) ;Valdebenito, Reinaldo ;Waher, Peter ;Forcael, Eric ;Martínez, EderThis paper proposes and evaluates an automated BIM-Blockchain workflow to certify BIM design changes as verifiable digital evidence, aligned with ISO 19650-oriented traceability indicators. First, baseline traceability was assessed through a two-layer checklist (technical and operational) applied to a real residential BIM project developed in Revit®. Then, an end-to-end certification pipeline was implemented, where each relevant modification is exported as validated BIMXML, hashed for integrity, embedded into a BIMRegister-based smart-contract record (LegalLab), digitally signed with a timestamp (NeuroAccess), and immutably registered on a permissioned ledger (NeuroLedger) with tokenized event logs and QR-based third-party verification. Results show that, in a validation limited to one residential BIM model and three representative design changes, the prototype consistently produced complete evidence packages, increasing operational compliance from 20% to 80% and raising the global traceability index from 50% to 80%. Thus, the light-on-chain approach enhances accountability and auditability without storing full BIM models on-chain or disrupting routine BIM/CDE activities. © 2026 International Association on Automation and Robotics in Construction.

Item type:Publication, Uncertainty quantification of compressive stress response in expanded polystyrene foams using evidential neural networks<jats:p>This study investigates the application of Deep Evidential Regression in shallow feed-forward neural networks to model and quantify the compressive stress response of expanded polystyrene foam. This foam material, widely utilized for impact protection and packaging, exhibits distinct mechanical behavior characterized by elasticity, plateau, and densification stages during compressive loading. This research adopts a data-driven approach, leveraging artificial neural networks enhanced with evidential learning to predict the distribution of stress responses, thereby addressing both aleatoric and epistemic uncertainties. The methodology involves organizing stress-strain data into training, validation, and test sets, adding noise to simulate real-world conditions, and training models with evidential layers. Results demonstrate that the proposed models maintain high predictive accuracy, with coefficients of determination exceeding 0.90 for noisy test data and above 0.99 for noise-free data. The evidential regression models also provide robust uncertainty quantification, essential for applications where data quality varies. This study’s findings highlight the efficiency and effectiveness of Deep Evidential Regression in enhancing the reliability of stress-strain predictions for EPS foam, offering significant potential for broader application to similar foam materials.</jats:p>31
