In this study, the effects of six operating conditions on the performance of a 3 kW- ORC (organic Rankine cycle) system were investigated. The results of experiments show that, despite differences in the physical parameters of the three working fluids used, the performance of the ORC system was similar. Further, the cooling water temperature (CWT) was strictly controlled, but the experimental results were affected by the condensation temperature, however the experimental system can maintain stable operation.

Methods: Survey data from 400 older individuals in China was employed to assess the impacts of four domains of risk factors (demographic, health status, physical activity and neighborhood environment) on overweight/obesity. Six machine learning algorithms were utilized for prediction, and SHapley Additive exPlanations (SHAP) was employed for model interpretation.
