A line-defect waveguide hosted in a 2D honeycomb photonic-crystal slab is demonstrated theoretically to realize polarization-independent waveguiding. Through an appropriate set of design parameters, a normalized bandwidth of $\sim 2$ % subject to the condition that the common-frequency region between the transverse-electric and transverse-magnetic polarizations reaches the maximum value for a silicon-on-insulator...
English online learning system is needed as the background, the college English teaching practice in order to improve the teachers' teaching efficiency, the reform of students' learning mode, promoting informatization, standardization and scientific management for the purpose of the development of software systems. Of college students' English learning in order to realize the management informationization...
A hybrid course curriculum design and implementation based on CDIO approach to engineering education is presented. The course is “fundamentals of electric circuit” for undergraduates of electrical engineering and automation program. The relation of the university motto is analyzed and mapped to CDIO directly. The curriculum design conducts CDIO ideas to classroom teaching, lab experiment and other...
The anonymity of the social networking sites makes the spreading of the electronic word of mouth be affected. In this paper, we studied the main effect elements in them, then in this article we do the classification and point out some factors are playing a role through trust based on the ability and goodwill, trust based on the system, trust based on the threat, trust based on the sense of belonging...
The water quality of the Sancha Lake has declined from Class III to Class IV and Class V due to increasing eutrophication, to which human activity has contributed considerably since it was built in 1977. This research examines changes in sedimentation rate and supply of mass accumulation of the Sancha Lake in recent decades through 210Pb and 137Cs dating and records of historical events in lacustrine...
The problems are analyzed during the teaching process of analog electronics course. To solve these problems the project-based learning method (PBLM) is used to explore the teaching reform theory and practice. In the light of characteristics and requirement of analog electronics course, the five key steps of PBLM is designed and introduced by a practical example. Practice of teaching students shows...
