Flow testing of fuel nozzle tips and passageways is of critical importance, especially for multinozzle systems and DLN operation. Equalized fuel flow minimizes temperature spreads and can-to-can pressure differences between the combustors. The flow-test units use a computer-controlled system that calc...
The results show that XGBoost has better predictive performance than Gradient Boosting Decision Tree (GBDT) and Ordinary Least Squares (OLS) regression, and is more suitable for the small-sample well-log data in this study than Long Short-Term Memory (LSTM) networks. Based on this, Shapley ...

Proton exchange membrane fuel cells convert hydrogen and oxygen into electricity without emissions. The high cost and low durability of Pt-based electrocatalysts for the oxygen reduction reaction hinder their wide application, and the development of non-
The sample preparation and measurement are described in Supplementary Information Section 4. Although the thin film measurement provides the bulk and interfacial resistances, these parameters both depend on multiple properties of the ionomer: the solubility, diffusivity, and interfacial permeation rate ...
fuel consumption patterns. Torching was rare in both operations. Given the similarity in weather conditions and fire behavior, as well as the relatively small sample size, findings derived from the observed prescribed burns represents only a narrow range of possible fire effects in redwood forests....
4.2 Fuel cell testing The fuel cell testing is the most trustworthy and usual method used to evaluate the cell performance. To make a preliminary diagnosis and identify the major losses, it is mandatory to obtain a polarization curve, such as the one shown in Fig. 4.3. Then, in situ diagn...
Chemical modeling was used to predict the temperature and composition of the sample in the combustion zone. Moreover, kinetic modeling was used to simulate the reduction zone. The initial temperature and the simulated composition of the reduction zone were obtained from the chemical products taken ...
