As the 3D stacking technology still faces several challenges, the 2.5D stacking technology gains better application prospects nowadays. With the silicon interposer, the 2.5D stacking can improve the bandwidth and capacity of the memory system. To satisfy the communication requirements of the integrated memory system, the free routing resources in the interposer should be explored to implement an additional...
The study uses augmented reality (AR) technology to integrate virtual objects into the real learning environment for language learning. The English AR classroom is constructed using the system prototyping method and evaluated by semi-structured in-depth interviews. According to the flow theory by Csikszenmihalyi in 1975 along with the immersive factors from Trevino and Webster in 1992, the proposed...
The test system of light hybrid power train can test the overall performance and key components, which can shorten greatly the development cycle and costs of cars. According to the structure characteristics and working process of a light hybrid vehicle, the specific design idea of the testing system has been put forward in the paper. The battery test system and operation interface are detailed.
Early detection of pathogens is important for surveillance and control of infectious diseases among Phalaenopsis orchids. Therefore, the current study presents an integrated microfluidic system for rapid and automatic detection of Phalaenopsis orchid viruses. The entire process, including pathogen-specific ribonucleic acid (RNA) purification, nucleic acid amplification using reverse transcription...
The study aims to exam if there were significant differences among urban and rural elementary schools in the implementation of ICT education. The study focused on information technology curriculum. A questionnaire according to three dimensions (learning, instruction, surroundings of learning) was the measurement tool for the study. The target population was all 5th grade schools students from three...
With the widely applications of CAD, it is important to manage the workflow in the design systems. According to the characteristics of CAD collaboration design, combining the advantage of state chart and Semaphore mechanism, this paper first proposes a workflow management system based on state chart, then discusses its key technology and demonstrates its application in the workflow management of collaborative...
Current steganalysis for images is not universal, which is usually special for one kind of steganography and not practical for others. Meanwhile the correct detection rate of these detecting methods is not high. After analyzing current steganalysis methods, a new steganalysis method for detection of steganography in image's frequency domain is proposed. The detecting method is universal and is not...
Taking the Chinese-Singapore cooperation project as example, combine the feedback from questionnaires and interviews of students about the bilingual teaching using teaching material in English in the course Operating Systems, proceed from the whole teaching process, include teacher's teaching, students' preparation for class, students' sitting on a class, teacher's after-class tutorial, teacher's...
The objective of this study is to design a game-based learning framework based on motivation approach. According to the framework, a system, GPS-E, was developed and tailored for fall-behind learners whose biggest problem is lack of motivation about learning English. After analyzing the questionnaire about students' attitude toward learning English and playing digital games, result shows that motivation...
Designing efficient and secure group key agreement scheme is one of the key issues in mobile ad hoc networks. In this paper, a novel group key agreement scheme for mobile ad hoc networks based on threshold secret sharing is proposed. In the proposed scheme, the key management and agreement is completed by multiple subgroup key managers and the group key manager of all the users in mobile ad hoc networks,...
Switch machine is of fundamental significance among the railway track switch equipment. Therefore, the autonomous dynamic monitoring of railway switch contact intensity of switch machine has always been an important part in the study to ensure safe railway transportation. Based on the improved Hough transform and K nearest neighbour algorithm, the method studied in this paper can effectively detect...
