Although their purpose is not to extinguishing a fire, passive fire protection aims to delay flame and smoke propagation, gaining valuable time to save lives and goods. Fire doors are amongst the most common protection devices, and they must undergo strict certification tests to ensure they meet fire resistant standards. Such tests are expensive and time consuming, often carried out at longer distances in specialized facilities. Computational tools could provide a cost effective alternative to direct the design towards a viable product. Thus, with the objective of assessing the effectiveness of computational tools in the certification processes, a numerical model of a single-leaf sandwich door was developed. The simulations were carried out in Ansys Mechanical, using a one-way coupling approach between transient thermal and transient structural analyses. A key aspect of the model is the temperature-dependent convective heat transfer coefficient on the unexposed face, which greatly influences the predicted temperature evolution. From the numerical results, one may infer the maximum temperature of the door, as well as its displacements at the upper and lower edges. Thus the numerical model highlights the potential of using this methodology by allowing not only the temperature evolution to be recorded throughout the test at specific positions of the assembly, according to the standards, but also the identification of potential gaps between the door and the frame, which is critical for fire and smoke containment. Future work includes conducting an experimental trial to validate the model and refine the heat transfer parameters for improved predictive accuracy.

The…Nonlinear dynamics are frequently encountered in industrial processes, where conventional linear controllers often fail to ensure the required performance or safety due to phenomena such as multiple equilibria, limit cycles, and bifurcations, all of which can negatively impact system stability. These challenges necessitate control strategies that can adapt to changing operating conditions and capture nonlinear behavior more effectively. Building on earlier research, this study identifies and evaluates two promising approaches to model-based adaptive control suitable for nonlinear technological processes. 
    Within an established classification framework, two representative strategies are examined: one based on sequential linearization combined with polynomial control, and another employing a direct nonlinear method based on the Wiener model. Experimental validation is conducted on a two-tank benchmark and a continuous stirred-tank reactor, both representing typical nonlinear industrial systems.
    The results show that sequential linearization in combination with polynomial control achieves faster set-point tracking, quicker convergence, and greater robustness compared to Wiener model control. These findings underscore the advantages of structured sequential linearization techniques within adaptive control and demonstrate their potential as a practical and effective alternative to purely linear control designs in complex nonlinear environments.
