A metaheuristic approach to model the effect of temperature on urban electricity need utilizing XGBoost and modified boxing match algorithm
Different factors can impact the demand for electricity, including weather conditions, industrial composition, population expansion, and economic progress. Temperature is particularly significant among these factors, as it has a major effect on electricity usage, especially in city regions where heating and cooling systems are extensively utilized.
Research on insulator defect acoustic signal recognition method based on CNN-GRU
In the power sector, the stability of transmission lines is essential for the effective functioning of the power system.1 Transmission lines play a critical role in the long-distance transmission of electrical energy, acting as a fundamental component of the power grid’s overall operation. However, since transmission lines are exposed to the outdoors for most of the time, they are very susceptible to external forces, which can lead to faults.
Effects of aluminized charge structures on blast wave propagation and the parameters of partially confined explosions
The partially confined explosion processes of charges were simulated for a blast in a cubic cabin with a pressure relief port diameter of 100 mm by using three-dimensional LS-DYNA in this work. The following conclusions were obtained: During a partially confined explosion, the blast wave will generate local pressure convergence at the junction and corner areas of adjacent walls in the cabin structure due to wave reflection.

Consistency between the distributions for the two phases in aeolian sand transport: Impact of sand on wind
Aeolian sand transport is the main cause of land desertification and aeolian geomorphology formation. Therefore, studying this process is of great importance. Field observations of aeolian sand transport began in the 1940s (Bagnold, 1941; Chepil, 1945).
A CNN-LSTM model for predicting wind speed in non-stationary wind fields in mountainous areas based on wavelet transform and adaptive programming
In actual production, the collected wind speed values are often affected by the collection environment and collection equipment, and there will be many interference signals. Hence, the initial sequence employs WT to break down the noisy wind speed sequence into multiple comparatively stable components. Subsequently, it leverages the strengths of both CNN and LSTM models to formulate the WT-CNN-LSTM model for wind speed prediction.

Be vulnerable, do not hide emotions in prayer
Published: January 28, 2021 By Noah Koch Special to Arkansas Catholic Every person on this planet has God-given gifts called emotions. We were given emotions to help us live our lives to the fullest and make many great memories. The emotions we feel have another purpose, though: they indicate where we believe we stand with God. It can easily be seen in prayer.
