The optimization problem is formed based on a preselected value for the fundamental natural frequency, and it is formulated for minimum structural weight. In a two-step approach, first, an alternative formulation aimed at maximizing structural stiffness that in turn maximizes structure's fundamental ...

This study focuses on evaluating the ability of conventional and deep learning time series methods such as seasonal autoregressive integrated moving average (SARIMA), long short-term memory (LSTM) neural network, and gated recurrent unit (GRU) in estimating the current and future global mean SLR. ...
starting in May 2022, briefly gave scientists cause for concern. A year later, things calmed down to normal levels. By that time, researchers had recorded 1,800 earthquakes beneath the volcano during its period of unrest. Still, the likelihood of another super eruption...
But experts say there's an underlying problem that, unlike inflation, isn't going away anytime soon — the heat. An unreliable national grid Recent years have seen back-to-back heat records across the world, including in the U.S. Rising temperatures fuel extreme weather events, such as...
