Summary: The Convolutional Neural Network (CNN) method is used to predict the performance of an all-glass straightthrough evacuated tube solar collector. The CNN-model outperforms Multiple Linear Regression (MLR) and Back Propagation (BP) neural network models in terms of prediction accuracy, with the lowest Root Mean Squared Error (RMSE = 0.00577), the lowest Mean Absolute Error (MAE = 0.00357), and the highest Coefficient of Determination (R2 = 0.9534). The CNN-model also shows that solar collector performance is more influenced by solar irradiance and mass flow rate than by wind speed and outdoor temperature.

Summary: Hybrid gels (HGs) are double-component systems formed by combining oleogel and hydrogel. The ratio of hydrogel to oleogel is an important parameter affecting the properties of HGs. In this study, grape seed oil and beeswax oleogelator were used to prepare oleogel, and different ratios of sodium alginate dispersion were mixed with oleogel for the preparation of HGs. The optimal ratio was found to be 5:95 based on thermal and chemical analyses. The selected HG was then tested as a substitute for Cocoa Butter Substitute (CBS) in compound chocolates, with 15% replacement showing the most similar characteristics to the control sample.

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.
