A Two‐Way Coupled Simulation Framework for the Prediction of Fire‐Induced Damage and Smoke Propagation in a Building

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The contribution is concerned with a fully coupled simulation methodology for fire‐induced damage in concrete structures. Fire events in buildings not only generate high temperatures and the spreading of smoke gases but also induce significant structural damages of the concrete structure.

Topological design and control of buck-boost multilevel inverters [PDF]

open access: yes, 2019
Most dc-ac inverters developed to date can support only voltage buck energy conversion, and are therefore not suitable for use as interfacing inverters for tapping energy from renewable sources or other alternative clean sources like fuel cells, where an unrestrained voltage variation range is unavoidable.

Comprehensive Review of Hybridization of Kenaf Fiber/Banana Fiber Filled Polymer Composites in Automobile and Aerospace Industries

open access: yesSPE Polymers, Volume 7, Issue 4, October 2026.
Hybridization of kenaf and banana fibres in aerospace and automobile applications. ABSTRACT Natural fiber reinforced polymer composites have been extensively studied as a result of the automotive and aerospace industries' need for lightweight, durable materials and the growing environmental concerns surrounding the production of synthetic fibers.

Target Capture of Ancient Shell DNA Enables Phylogenetic Reconstruction of Deep‐Sea Molluscs

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates remains poorly understood. Here, we compared DNA recovery from four fresh and 12 ancient (eight radiocarbon‐dated to 1671–1135 years old before ...

Enhancing Reference Tracking in Induction Motor Drives: A Hybrid Model Predictive Control and Artificial Neural Network Approach

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 14, Page 6719-6738, 25 September 2026.
ABSTRACT Induction motors (IMs) are widely used in industry for their robustness and cost‐effectiveness, yet their nonlinear and multivariable dynamics pose significant challenges for high‐performance speed control. Model Predictive Control (MPC) is a well‐established solution but suffers from limitations related to model accuracy and parameter ...
