Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Principal investigations of the application of a hybrid, consisting of an artificial neural network (ANN) and a conventional numerical method to predict an exemplary flow field are presented. Topics of the work were to show principle possibility of using ANN in fluid mechanics and to show the potential of integrating physical a priori knowledge into the training procedure. The flow fields for training and evaluation were generated by a numerical algorithm. Major result was that prediction of the flow field, including the existence of vortices in the bodies outflow at higher Reynolds numbers can be realized in much shorter times than necessary for numerical calculation. The results were obtained with training data, which represented totally different relations in their dynamical behavior, depending on the geometric location. Furthermore, physical a priori knowledge was included in the learning process with an obvious improvement of the hybrid models performance.
