3D objects with features spanning from microscale to macroscale have various applications. However, the fabrication of such objects presents challenges to additive manufacturing (AM) due to the tradeoffs among manufacturable feature resolution, maximum build area, and printing speed. This paper presents a projection‐based AM process called hopping light vat photopolymerization (HL‐VPP) to address...
Meningioma is the most common primary central nervous system tumor, and its incidence is increasing. A systematic epidemiological and clinical analysis is required to better estimate its public health impact and understand its prognostic factors. Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2018 for all types of meningiomas without an age restriction...
The conventional approach of parameters design for power system stabilizer (PSS), which aims at a special mode of low-frequency oscillations can not have the damping effect on wide range of low-frequency band. This paper presents a new approach to implement the parameters optimization of PSS controller. With genetic algorithm(GA), this approach can have better damping effect on all the main frequency...
