- Experimental towing tank tests were conducted on two 40-foot scaled beam-type planning vessel models equipped with adjustable trim tabs.
- Results show that optimal trim tab deployment significantly reduces hydrodynamic resistance and lowers the hump resistance region.
- Trim Tab configuration “B” enabled earlier planning transition, reduced bow impact, and lowered power demand compared to untrimmed and Tab A cases.
- Scaling effects, model construction tolerances, and ITTC-recommended procedures were carefully addressed to ensure fidelity with full-scale performance.
- Findings provide practical insights into improving propulsion efficiency, vessel stability, and structural safety in high-speed marine craft design.

- Developed LHS-FEM database to predict MVMS in corroded pipelines using ML.
- Integrated ABAQUS with Python to automate nonlinear FE analysss for pipeline defects.
- Evaluated five ML models with grid search and k-fold to optimize prediction accuracy.
- NN and DTR models performed well in predicting MVMS; NN showed robust generalization.
- Used learning curve analysis and PI method to validate models and assess parameters.
