Based on the discussion of the influence factors and status quo of Honing reticulate pattern processing technology, the paper makes simulation analysis of the reciprocating reversing acceleration of honing machine, in order to uncover the impact of acceleration changes upon the main Honing process parameters...

Based on three periods(year 2000, 2008 and 2013) Landsat images and basic geographic data of the region, the vegetation cover change detection of the north-south mountains in Lanzhou city was quantitatively analyzed and dynamically monitored with calculating of the normalized difference vegetation index...

To investigate the mechanism of new quality productivity on high-quality economic development and the dynamic impacts of marketization level and informatization level, this paper builds the mediating effect model and the moderated mediating effect model using panel data from 30 Chinese provinces from...

Virtual reality technology can help students enter the virtual teaching scene, satisfy students’ multi-sensory experience teaching, and promote the effective occurrence of teaching. Simulation technology can create realistic virtual scenes, which provides the possibility of virtual visualization for...

It is an under-determined problem that local methods are used for face alignment of an image, although good results can be obtained by using an auxiliary model or a priori information. In comparison, joint alignment using multiple face images of the same person has more advantages. In this paper, the...

Aimed at the characteristics of the existing stretch leg rehabilitation products with single function and complicated structure, a leg stretching training device with multiple training modes is proposed. At the same time, a controller strategy based on fuzzy slip film algorithm is proposed for the constant...

A current-fed bridgeless interleaved power factor correction rectifier with voltage-doubler characteristic is proposed for a hybrid electric vehicle charging system. The simulated efficiencies, Total current Harmonics current Distortion (THDi), and Power Factor (PF) for the bridgeless interleaved Power...

Purposes To explore the relationship between college students' family function, self-differentiation and mobile phone dependence. Methods Using convenient sampling, 430 undergraduates were selected from a college in Wuhan City. Questionnaires using Mobile Phone Dependency Index (MPAI), Family Function...

Since the beginning of 2020, the new crown epidemic has been a global problem. Many industries have been severely affected by the pandemic. Depending on the company’s response and the strategy adopted by the entire industry, the impact of the epidemic on the industry can be negative or positive. It is...

Because of some pixels of foreground image which is binarized by fixed threshold, the Gaussian mixture model can not get accurate result. So we introduce OTSU to look for the threshold which satisfy maximum-between-clusters-variance,and it will get best divisional effect.It achieve adaptive threshold...

At present, there are few studies on the treatment of primary dysmenorrhea of cold coagulation type primary dysmenorrhea with traditional Chinese and western medicine at home and abroad. The study of blood deficiency and cold coagulation type of primary dysmenorrhea are alpine stagnation with qi and...

A new clonal selection immune algorithm with perturbation guiding search and non-uniform hypermutation (nCSIA) is proposed based on the idea of perturbed particle swarm algorithm and non-uniform mutation. The proposed algorithm proportional clones antibody based on the affinity, adaptively adjusts the...

Aiming at the disadvantages of the traditional artificial potential field method, target is not reachable and the robot is easy to fall into local minimum point, the paper proposes an improved potential field function of arti-ficial potential field, a formula factor is added to the repulsive force field...

Charging, discharge, maintenance and energy management technology for electric vehicle power battery is relatively backward, An advanced and reasonable method is presented for battery state of charge( SOC ), used simple rough set attribute ,simplified battery charging related parameters, the simplified...

China's corn straw resources are very rich, the development of corn straw application technology industry has become a hot spot. In this paper, the present situation of comprehensive utilization of corn straw in China is summarized, including the utilization of corn straw as fertilizer, feed, raw material,...

The numerical analysis course which is a widely applied and strong discipline mainly introduces the basic theories and methods of scientific computing. This paper discusses teaching concepts, textbook content, teaching links, and teaching methods combined with Mathematica software.
