Summary: The problem of fuel reloading optimization requires searching for the optimal core configuration in a huge solution space. The use of meta-heuristic algorithms and artificial neural networks has been effective in updating optimization solutions and evaluating core configurations respectively, but there is little research on the application of convolution neural networks. Aiming to solve the problems in fuel reloading optimization for block-type HTGRs, triangle-filter convolution neural networks are developed and applied with genetic algorithm and particle swarm optimization. The results show that the TFCNNs can accurately predict optimization parameters and have a faster calculation time compared to DRAGON V4 program and a higher ratio of feasible solutions compared to BP-ANNs.

Summary: In recent years, there has been significant interest in reducing global carbon emissions, leading to stricter policies and regulations. For high power-density marine diesel engines, optimizing fuel consumption is difficult due to the large injection mass and little intake swirl. This article proposes a concept of rapid and controllable combustion to address this issue, which involves optimizing the combustion process based on the Sabathe-Miller cycle and determining controllable parameters through the evolution of in-cylinder spray.

Summary: A novel method called Kalman filter was investigated to predict the pyrolysis mechanisms of four different biomasses and compared with regression analysis. The models with reversible reactions in addition to parallel pyrolysis steps showed a better fit with the experimental results. The pyrolysis step from biomass to bio-oil exhibited the highest reaction rates compared to other defined pyrolysis steps in the models. Kalman filter is considered a promising method for estimating detailed pyrolysis mechanisms and model parameters with minimum experimental data.

Summary: This study applies artificial neural network (ANN) models to predict the higher heating value (HHV) of biomass feedstocks and comprehensively analyzes the factors that affect the prediction, including activation functions, algorithms, hidden layers, dataset, and randomization. The results show that using ANN models trained by the combination of ultimate-proximate analyses (UAPA) datasets, with sigmoidal activation functions (tansig and logsig), and with Levenberg-Marquardt (lm) or Bayesian Regularization (br) algorithms as training activation functions, can provide accurate HHV prediction.

Summary: Ammonia is a promising carbon-free alternative fuel for reducing carbon emissions in marine engines. The study found that ammonia-diesel stratified injection technology can significantly reduce CO2 and NOx emissions, improve energy ratio, and meet future low-carbon emission regulations without the need for after-treatment. Increasing injection pressure and reducing pilot fuel proportion is the optimal solution for achieving high IMEP, low NOx, and carbon emissions.

Summary: This article introduces a confidence interval based distributionally robust real-time economic dispatch (CI-DRED) approach, which addresses the risk associated with accommodating wind power. By developing a novel ambiguity set based on imprecise probability theory and transforming the original nonlinear dispatch problem into a determined mixed integer linear programming problem, the proposed method effectively balances operational costs and risks. Numerical results on both the IEEE 118-bus system and a real 445-bus system demonstrate the efficiency and effectiveness of the approach.
