In the China VI regulations for light-duty vehicles, (RDE) test is introduced as a supplementary procedure. actual process, RDE results are more significantly influenced by driving behavior and vehicle type. To reduce cost, NOx PN prediction models established based on GA-BP method. The showed that coefficients of determination model predictions all greater than 0.9 linearly highly correlated a...
With the ever-growing availability of massive geo-data, deep learning has been widely applied to geoscientific questions such as sedimentary provenance analysis. However, randomly selected initial weights (and also biases) and possible loss population diversity in traditional neural network remain problematic. To address this issue, study, we proposed a new model by incorporating genetic algori...
Background: Blood pressure (BP) is an important vital sign and indicator of clinical stability. Therefore, the accurate measurement and interpretation of this physiological signal is essential for the optimal management of ill newborns. In this regard, the present study aimed to determine BP values and percentiles in stable newborns in the first weeks of life and evaluate the relevant factors.<...
Due to the inaccuracy of preset rolling force cold rolling, there is a severe thickness defect in strip head after due flying gauge change (FGC), which affects yield strip. This paper establishes model (RFPM) by combining optimization (RFOM) and deviation prediction (RFDPM). The RFOM used genetic algorithm (GA) optimize deformation resistance friction coefficient models. RFDPM constructed using...
