Accurate and rapid recognition of coal gangue is an important prerequisite for safe efficient mining in top caving face. In this paper, a novel coal-gangue method put forward based on improved ant-lion optimization algorithm (IALO), variational modal decomposition (VMD) MobileNetV2 network. Firstly, two strategies trap boundary adjustment chaotic mapping are designed ALO to sufficiently explore the solution space prevent falling into local optimization. Subsequently, IALO employed search...
Abstract With the energy upgrade of China Spallation Neutron Source (CSNS-II) and increasing demand for isotope production, RF repetition frequency Drift Tube Linac (DTL) accelerator must be elevated from 25 Hz to 50 Hz. However, shifts induced by heating exceed current tuning range. Traditional methods cannot applied during DTL operation, so online technology is explored in this study. Multi-physics simulations were used analyze electromagnetic temperature distribution, shifts, compensation...
Elliptical superconducting cavities are widely used in particle accelerators because they can provide stronger acceleration fields than regular cavities. Pre-tuning is required to improve their performance, but the process time-consuming. This research introduces an automated pre-tuning system for multi-cell elliptical platform integrates three main components: real-time electric field measurements, data analysis based on tuning algorithms, and mechanical adjustment systems. During copper...
Soft proofing technology is the development of new technologies in recent years, application becoming more widely. As use display image simulating hard copy image, settings, ambient light conditions and observe will affect impact soft proofing. 68 pairs test images own average value different color originated from four typical by transfer functions. In manipulation progress, each original was altered two aspects: lightness, chroma respectively .Using EIZO CG19 to show conditions. A visual...
