Here, we employ the IMETF method to derive exact solutions for Eqs. (1) and (2). The solutions are assumed to have the following form:
$$\begin{aligned} \begin{aligned} u(x, t)&= U(\xi ) \exp [i (- k x + \omega t)], \\ v(x, t)&= V(\xi ) \exp [i (-…

Integrating system dynamics and machine learning for environmental impact analysis of building materials in the demolition process
System dynamics (SD) model development
The SD model was developed to assess the environmental impacts associated with the demolition tools used in building demolitions in Thailand. This model is comprised of eight interlinked sub-models: (1) the…

An adaptive spatiotemporal dynamic graph convolutional network for traffic prediction
Datasets
To comprehensively evaluate the performance of AST-DGCN, we utilize four real-world datasets from the Caltrans Performance Measurement System (PeMS)39: PEMS03, PEMS04, PEMS07, and PEMS08. The distribution of traffic detectors for PeMS is…

Training a high-performance retinal foundation model with half-the-data and 400 times less compute
RETFound-Green
Like RETFound-MEH and DERETFound, RETFound-Green uses the original vision transformer architecture27 but with four extra “register tokens”38 that do not relate to a specific patch. This is a minor and straightforward…
