In order to develop a new and effective prediction system, the full potential of support vector machine (SVM) was explored by using an improved grey wolf optimization (GWO) strategy in this study. An GWO, IGWO, first proposed identify most discriminative features for major prediction. approach, particle swarm (PSO) firstly adopted generate diversified initial positions, then GWO used update current positions population discrete searching space, thus getting optimal feature subset better...
We report on the effect of 500 keV He[Formula: see text] ion implantation with a fluence [Formula: ions/cm 2 Rb[Formula: text]-K[Formula: exchanged KTiOPO 4 optical waveguide. The refractive index distribution after implantation, exchange, and subsequent exchange were reconstructed by reflectivity calculation method, inverse Wentzel–Kramers–Brillouin, intensity respectively. near field waveguides was simulated Beam Propagation Method. phase analysis samples measured X-ray diffraction...
We report on the fabrication and characterization of KTiOPO4 optical waveguides formed by Rb+-K+ ion exchange in high-purity RbNO3 melt at 340°C for 90 min subsequent He+-ion irradiation energy 500 keV fluence 3×1016 ions/cm2. The crystals with He+ ions was simulated using stopping range matter (SRIM’2006) software. dark mode spectra samples were measured prism coupling method. reconstructed refractive index profiles planar waveguide show a barrier middle guiding region, enhancement region...
Aiming at the problems in parameter measuring of small-size workpieces, a real-time detection system is developed based on machine vision. The system’s hardware composition and software design proposal are introduced, method using digital image processing technology to measure geometrical size elaborated. First, acquired through industrial camera system. Then, sent unit for processing, including filtration, template matching edge detection. Finally, sizes measured calibration information...
Green pesticide use, as a key means to reduce plays crucial role in promoting environmental and food safety. However, the effectiveness of green use policies China falls short expectations. Existing research mainly examines policy promotion issues from static single-agent perspective. behavior is dynamic process influenced by multiple factors, including government, farmers, consumers. This paper builds an evolutionary tripartite game model consumers perspective strategy evolution explores...
Abstract As the energy spread of intense pulsed electron beams (IPEB) strongly influences irradiation effects, it has been great importance to characterize IPEB spectrum. With combination Child–Langmuir law and Monte Carlo simulation, spectrum obtained in this work by transformation from accelerating voltage applied diode. To verify accuracy simple algorithm, a magnetic spectrometer with an imaging plate was designed test The measurement completed generated explosive emission diode, pulse...
Abstract As a kind of flash heat source, intense pulsed ion beam (IPIB) can be used for material surface modification. The ablation effect has important influence on interaction between IPIB and material. Therefore, the understanding mechanism is great significance to application. In this work, pure zinc targets were irradiated ablated by IPIB. process under different energy densities, products collected monocrystalline silicon substrate. By analyzing with scanning electron microscope...
To the question of particle images segmentation with uneven illumination background, a novel method is proposed based on homomorphic filtering, Top-Hat transformation and watershed algorithm in this study after discussing characteristic various common algorithms. Firstly, filtering carried out image frequency region space, which weakened low component strengthened high appropriately, to make whole evenly. Then, adopted remove large area target background segment target's active area....
