Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Comfort in the canopy: How urban treescapes affect human thermal comfort in a temperate climate

People and Nature, EarlyView.
Abstract People living in urban centres are exposed to higher levels of heat stress than those living outside of these areas; this is intensified by the urban heat island effect. Heat stress is a concern for the more vulnerable members of society and can exacerbate many medical conditions; excessive heat increases morbidity and mortality rates.

Influence of transient conditions on thermal comfort evaluations: Field study in university buildings

Case Studies in Thermal Engineering
Thermal comfort is directly associated with the user’s health, performance, and energy consumption, making it a focal point of attention over the years. The static model heavily relies on the thermally steady state to assess thermal comfort.

Optimization of Flexural Strength of PLA Flexural Test Specimens Produced by FDM Using Taguchi L27 Orthogonal Array and Hybrid Regression Model

Journal of Polymer Science, EarlyView.
This study investigates the impact of FDM process parameters on the flexural strength of PLA components using a Taguchi L27 orthogonal array. Analysis reveals wall thickness and layer height as the primary determinants of mechanical performance. A highly accurate regression model is developed, providing a robust predictive framework to optimize 3D ...
