“…With the advent of the cloud era, marked by cloud storage and cloud computing, how learners learn online is becoming increasingly diverse. e data from many cloud learning platforms provide strong support for personalized learning research and prediction [4]. However, since the existing classroom environment is still the primary environment for learning, it has richer data on learning behaviors.…”

In this paper, we conduct an in-depth study and analysis of “Internet+ Business English” teaching through teaching big data model and visualization and elaborate on the change of educational objectives in the context of Internet education. From the perspective of individual value coordinates, the goal of education is to adhere to the people-oriented, personalized, and comprehensive free development of human beings; from the perspective of social value coordinates, the goal of education is to cultivate innovative talents for social innovation and development; through the multiple perspectives of the curriculum in the context of Internet education, we analyze the goal orientation and value reshaping of the curriculum in the context of educational change. The curriculum of the future will develop toward an intelligent curriculum and introduces the curriculum design and the form of curriculum organization in the context of Internet education. A comparison of the constructed regression and classification of a total of 27 data models reveals that the model constructed based on all data in the integrated education system is the most effective. The multiple linear regression model explained up to 66.5% of the variance in student academic performance; the explanatory power of the social and demographic characteristics dimension variables ranged from approximately 13% to 18%, the personal characteristics dimension variables ranged from 7% to 20%, and the student input dimension variables ranged from 10% to 17%. The highest correct prediction rate of the binary logistic regression model was 69%.

“…Ultrasound is an elastic mechanical vibration wave with a frequency of 2 × 10 4 ~ 10 7 kHz [34] . Ultrasound has been of great interest since the late 1920 s due to its high efficiency, environmental friendliness, and green effect, especially in chemical synthesis, because of its great potential and many features [35] . The cavitation effect of ultrasound has made its application more theoretically and practically relevant, which has led to more interest and research [19] .…”

“…Controlling, manipulating and amplifying EM waves are the most noteworthy and intriguing consequences, which PCs could demonstrate from themselves. The PBG based PCs are typically used in the following fields: microfluidic and biomedical sensors [15], polarization splitter [16], solar cells [17,18], Terahertz Sensor [19,20], integrated circuits [21], photovoltaic devices [22], photonic filters [23], etc.…”

Although there has been a focus on THz lters so far, there is a signifcant defciency in advancing low-temperature THz lters. According to the needs, we proposed a tunable THz lter that selectively permits the desired incident frequencies to be propagated in relevance with our purpose. The presence of a low-temperature nano superconductor and an undoped semiconductor layers in the proposed structure resulted in a multi-channel THz lter, which could be highly tuned with several parameters such as lattice constants, applied temperature, etc. The achieved transmittance spectra revealed that the emerged transmittance couples and stacks follow exact regulations. Furthermore, the structure exhibited omnidirectional band-gaps for both TE and TM polarized waves. Moreover, the use of a central defect layer gave some transmittance defect modes in the forbidden areas. This structure could be used in some THz devices such as switches, optimized sensors as well as in space industry and telecommunications.
