The integration of optimization techniques and deep learning models, which offer a promising avenue for improving the efficiency sustainability biodiesel production processes from baobab seed oil (BSO), is rare. This study utilized multi-input-multioutput (MIMO) technique most recent central composite design (CCD) tool to model optimize yield properties produced BSO. First, was extracted using solvent extraction method. BSO subsequently analyzed converted by reacting CH3OH catalyzed waste...

Constructing ecological networks in urban areas improves ecosystem stability and biodiversity protection. However, most studies focus on optimizing environments through objective assessments, often neglecting species diversity. This study developed a grading framework for the Jianghan Plain using observation diversity data. Supported by ArcGIS, sources were identified via MSPA graded Guidelines MaxEnt model. The MCR model was used to simulate connectivity barriers between calculate minimum...

Abstract The buckling analyses of a functionally graded superconducting thin circular plate with concentric small hole under the applied perpendicular magnetic field and/or distributed uniform mechanical load are investigated in this paper. Based on extended generalized Irie-Yamafuji critical state model, distributions current and flux density perforated firstly derived, corresponding electromagnetic body force is further numerically calculated. Then, based Kirchhoff theory two-point initial...

Abstract Cellulose nanocrystal (CNC)‐based aerogels hold promise as materials for piezoelectric sensors, given their biodegradability, cost‐effectiveness, and adaptable mechanical properties. However, cellulose‐based mechanoelectrical sensors often suffer from limited performance due to poor sensitivity output, arising inadequate stress transfer coupling. In this study, a novel metastructure with negative Poisson's ratio (NPR) is introduced boost the of aerogel sensors. To activate...

Abstract Thermal stability determines a material's ability to maintain its performance at desired service temperatures. This is especially important for aluminum (Al) alloys, which are widely used in the commercial sector. Herein, an ultra‐strong and heat‐resistant Al‐Cu composite fabricated with structure of nano‐AlN submicron‐Al 2 O 3 particles uniformly distributed matrix. At 350 °C, (8.2AlN+1Al ) p /Al‐0.9Cu achieves high strength 187 MPa along 4.6% ductility under tension. The good...

In a drawn vacuum arc, the arc sequence begins with bridge column formed after rupture of molten metal bridge. This evolves into transition mode, which consists central few or no cathode spots outside column, and then develops fully diffuse mode. this paper, influence ignition position on characteristics in mode was investigated experimentally demountable chamber. Practical cup-shaped axial magnetic field (AMF) contacts were used experiments. Arc aid high-speed digital camera an exposure...
