The cultivation of innovative practical ability of college students is an important part of higher education. How to solve the problems existing in the current college students' scientific and technological activities effectively is an important way to improve the practical level of college students. Through analyzing the current situation of college students' scientific and technological innovation...
The development of multimedia and network technology which provide a new carrier and platform for the traditional teaching, is also the foundation of hybrid teaching mode, which is a hot topic in the research of teaching reform in colleges and universities. Flipped classroom emphasizes the students as the subject, and the teacher as a supplement, which truly reflects the "student centered"...
In traditional teaching mode, Java technology course teaching is teacher centered, it is difficult to improve the students' interest of learning, the teaching effect is not ideal. Flipped classroom focuses on students centered, teachers as a supplement, and truly reflects the "students centered" philosophy of education. Firstly, this paper analyzes the current teaching situation and existing...
In order to study the influence of various design parameters of the Screw Die to the flow channel and extrusion uniformity, FEA (finite element analysis) was made by parametric modeling, parametric loading and solving, as well as parametric post-processing method. APDL (ANSYS parametric design language) and VISUAL C++ language were used to replace the work of ANSYS pre-processing function. Special...
The weak and small target image preprocessing in the digital video interpretation system is studied. In order to improve the detection ratio of single image, firstly, morphological wavelet transform is adopted to enhance small target in the low frequency image; and then, use morphological open-reconstruction filter and threshold technique to suppress the background and segment the small target; finally,...
In order to obtain a lightweight and high-stiffness main supporting structure of Space Remote Sensor, Main supporting structure of Space Remote Sensor with TMA optical systems were studied by way of Finite Element Method (FEM).The stiffness of the supporting structure was validated with normal modes analysis. In order to improve its fundamental frequency (the first order natural frequency), a topologic...
