This structural degradation reduces the available surface area for gas exchange, significantly impairing oxygen delivery to the bloodstream. While oxygen therapy is a critical intervention, the inherent physiological complexities, specifically transit time delays and dynamic respiratory demands, make precise oxygen regulation exceptionally difficult. To address these challenges, this study develops a comprehensive mathematical model of the emphysema-affected respiratory system, incorporating specific parameters for time delays in oxygen exchange. A novel Intelligent Set-point Modulated Fuzzy Model Reference Adaptive Controller (SFMRAC) is proposed to enhance oxygen regulation. This control architecture advances traditional Model Reference Adaptive Controller (MRAC) by integrating a normalization factor, fuzzy logic tuning, and set-point modulation. This hybrid approach allows the system to adapt to nonlinear physiological variations and maintain stability despite the transit delays characteristic of damaged pulmonary tissue. The effectiveness of the SFMRAC was evaluated through a simulation study conducted in MATLAB/Simulink. Results demonstrate that the proposed controller provides superior tracking performance and robustness compared to MRAC, particularly when subjected to varying set-points and significant exchange delays. The results suggest that the SFMRAC offers a promising computational framework to improve the automated delivery of oxygen therapy in clinical settings for COPD patients.

The capacity to produce polymer solar cells (PSC) at a reasonable cost and on a large scale remains a fundamental challenge. Because PSC manufacture mostly requires a vacuum atmosphere, which is an expensive endeavor, the facility for this procedure is currently somewhat remote. However, for a type of thin film solar cells where the components of the solar cell can be generated in a solution, more scalable and vacuum-free fabrication techniques are being developed. Examples of materials that could be handled in solutions are thin-film solar cells that contain all or some layers of polymer, dye-sensitized, quantum dot, and copper indium gallium selenide. After the solvent has evaporated, a thin layer will form on the substrate from the components that have undergone solution processing. This can be achieved by atomizing the solution and transferring the spray droplets to the substrate. Spray coating is a challenging fabrication approach, if it is possible to achieve reasonably uniform layers with high charge carrier separation and transport capabilities. This is because the coating is applied at atmospheric pressure using moderately priced equipment that can process rolls to rolls. Large scale production is possible by spray coating and few techniques are briefly discussed in this chapter.
