Continued development of lithium-ion batteries is limited by the shortage of Li element. In this situation, the exploration of high-performance sodium-ion batteries is attracting much attention. In this experimental work, Na2/3Ni1/4Mn34O2 film cathode materials were fabricated by excimer laser deposition at different oxygen partial pressures. X-ray diffraction studies and field emission scanning electron microscopy revealed high c-axis orientation and uniform grain distribution, respectively, in the deposited films. Furthermore, after 30 cycles under a current density of 13 mA g−1, the film samples deposited at an oxygen partial pressure of 65 Pa exhibited a high capacity-retention of 91%. The film structure also had a large-current discharge performance, which makes practical applications possible.

Abstract-This paper aims to analyze and discuss shadow removal algorithm based on HSV and RGB color spaces. By subtracting the current image with the use of background image we detect the removal targets in the video. This technique becomes an essential component for the background extraction; in this paper the approach we adopt consist to use the traditional Gaussian background modeling method to extract background. However, due to the impact of light and other effects, all obtained foreground image containing shaded regions, and all moving targets detected automatically will be impacted. To perform the effect related to this issue, we introduce RGB Color data instruction to detect foreground shaded region, and then detecting also the real method of removal targets; this is an effective method.Index Terms-Gaussian background modeling, RGB color space shadow detection. I. SHADOW REMOVAL ALGORITHMAccording to the level of research in shadow detection-suppression field, a variety of Shadow Algorithm has been developed by researchers during last decade. In this paper we introduce two shadow removal algorithms: the HSV color space shadow removal algorithm and RGB color spaces shadow removal algorithm. We adopt the RGB color space model to create hybrid Gaussian and avoid the region containing shadow effects. And firstly, according to the Pixel attribute, the algorithm can proceeding by determining pattern matching judgment, and use the Gaussian Mixture model to determine shadow pixel. The experiments show that the shadow removal algorithm can be out performed [1]. A. Shadow Detection Algorithm ResearchConventionally, shadow removal technique can be divided into two categories which are attribute model and pattern model. Shadow algorithm based attribute model nevertheless is seen as simple operation; however the technique requires robustness and inaccuracy characteristics. This section introduces two models based on shadow removal algorithms: HSV and RGB color space shadow removal algorithm.

A high-throughput, rapid and sensitive method of using ZIC-HILIC was developed for simultaneously qualitative and quantitative determination of melamine and triazine-related by-products including ammelide, ammeline, and cyanuric acid in food contact material. Linear responses were observed for samples ranging from 0.1 -200 ppb for melamine, ammelide, ammeline, and cyanuric acid with a correlation coefficient no less than 0.999. The method for simultaneous determination of melamine, ammelide, ammeline, and cyanuric acid in food contact material is sensitive and specific.

In this experiment, the stable output of a dual-frequency laser source is obtained by an acousto-optic modulator due to the Bragg diffraction effect. Furthermore, the non-polarized dual-laser heterodyne interferometer is designed to measure the micro-movement of stacked piezoelectric (PZT) ceramic. This micro-movement can be dynamically determined by comparing the phase difference between the conference beam and measuring beam. The results indicate that the micro-movement of PZT ceramic changes linearly with the driven-voltage in the range of 0–30 V and the sensitivity of movement to voltage is 58.3 nm/V, which is very close to the theoretical value and this laser heterodyne interferometer can be applied for calibrating parameters of PZT ceramic.
