The flow network model for power grids

A power grid is an interconnected network delivering electricity from generators to consumers. The electricity flowing through an AC power grid is normally denoted by complex power which is the vector sum of…

This section describes the three tests setup for tensile, dynamic and thermal characterization, whose adopted experimental setup are reported in Fig. 3a–c, respectively. Each test has specific goal in relation to the validation of the…

Cracking moment

The specimens designed in this paper are axisymmetric in cross section, so the center of form and center of gravity are not changed. Therefore, the concrete filled on both sides of the PECBWO steel web can be equivalently converted…

Spatiotemporal parameters

Results from the 6MWT showed significantly slower walking speeds (t = 3.315, p = 0.005, d = 1.658, large effect), lower nondimensional walking speeds (t = 2.944, p = 0.011, d = 1.472, large…

Data collection and analysis

The monthly stream flow and water level data are collected from the station from 2014 to 2023, this datasets pre-processed before applied models. The prediction of river water level modeling was created using two…

Cognitive phases

In digital human-computer interaction, human cognitive behavior will be changed. In addition to traditional cognitive ways, operators need to interact with software systems, decision support systems, navigation system, computer…

Peculiarities of the applied machine learning methods

The machine learning framework developed in this study exhibits several distinctive features that set it apart from conventional approaches applied in HF analysis. First and foremost, a…

Peck’s formula

In 1969, Peck²³ proposed a predictive formula for settlement troughs generated by tunnel excavation, assuming that soil deformation occurs under undrained conditions (as shown in the Fig. 5). He posited that the volume of actual…
