Summary: In recent years, biodiesel as a substitute for fossil fuels has gained increasing attention, although its production cost is higher. To reduce the cost, biodiesel has been produced from different feedstock based on local availability, but the feedstock quality limits the quality and efficiency of the transesterification process. The quality of biodiesel depends on fatty acid compositions and physicochemical properties of the oil feedstock, and the use of solid-based catalysts has been preferred due to their reusability and ease of separation. Different catalyst properties and process parameters also influence the transesterification reaction.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
