In this paper, a proportional integral (PI) controller that optimized with the modified different evolutional (DE) algorithm is proposed for speed control of brushless direct-current (BLDC) motor. The parameters PI are tuned by DE which based on adaptive mutation factor, multivariable fitness function and starting rule algorithm. performances controller, conventional standard (PI-SDE controller) investigated compared in simulation. Also, other optimization study. simulation results...
Abstract 3D printing, formally known as additive manufacturing, creates complex geometries via layer‐by‐layer addition of materials. While printing has been historically perceived the static build layers, is now considered a dynamic assembly process. In this context, here new process reported that executes full degree‐of‐freedom (DOF) transformation (translating, rotating, and scaling) each individual building layer while utilizing continuous fabrication techniques. Transforming layers...
Hydrogel, recognized as a promising biomaterial for tissue engineering, possesses notable characteristics, including high water uptake, an interconnected porous structure, and excellent permeability. However, the intricate task of fabricating hierarchically macro–micronanoporous essential providing adequate space nutrient diffusion cell growth within hydrogels, remains formidable challenge. In response to these challenges, this study introduces sustainable straightforward three-dimensional...

The HPHG features a multi-level porous structure (from 48 ± 28 nm to 4385 823 nm) that significantly enhances its porosity and specific surface area.
Fault diagnosis has a direct impact on the economic benefits of modern rotating machinery industry. The input current fault methods is mostly original vibration signal or time–frequency graph obtained by short-time Fourier transform. Both these inputs use many data points, which reduces real-time performance model. Therefore, novel model proposed to achieve high accuracy when points are few. First, two frequency domain (FDS) and (TFG) processing with fast transform continuous wavelet Then,...
