This paper describes the design of a professional development workshop on integrating robotics at the elementary and secondary school curriculum. The workshop was designed to support STEM education through teacher education at the university and post-university level. Moreover, the workshop leveraged the Technology Acceptance Model (TAM) and an interdisciplinary approach to engage teachers with robotics...
This paper collected the literatures (published in the last decade) of Human-computer Interaction from ISI Web of Science, and used the method of Mapping Knowledge Domains, to study the recent key topics and core documents in HCI. the results identify three research directions, including recognition technology, user interface design and usability study. the key topics in each direction and evolution...
In the electronic countermeasures (ECM) environment, the range of instantaneous dynamic signal is wide. Consequently, based on the principle of the match between the output voltage of RF front-end and the analog to digital converter's (ADC) full-scale voltage, the super heterodyne digital intermediate frequency (IF) receiver supporting instantaneous large dynamic range is designed for the direct sequence...
Based on the concept of the flooding algorithm and its improved algorithm the search algorithm in P2P networks is proposed based on the direction. This algorithm dynamically generates a search tree taken the source point to be its root which makes the search processing along the search tree. By this algorithm the production of redundant search packets can be effectively avoided in the search process,...
Due to the extensive application of automation of controlled greenhouse, computer-controlled conditioning system plays an important role in the greenhouse environment. This paper describes the composition of greenhouse computer control system, and the necessity of the computer control system in the greenhouse environment over the aspects such as the complexity of environmental management, energy saving...
For it has so many advantages multimedia supplementary teaching has been widely used nowadays. This paper introduces how to conform the multimedia and the environmental teaching on the basis of the practice of the environmental teaching. It also reveals several problems needing attention about the multimedia teaching process. In addition, it put forward that we should combine the multimedia teaching...
The diversity of osteotomy brings an obstacle to young experienceless surgeon to make preoperative plan. Computer-aided technique gives the birth of virtual osteotomy which assists surgeon with preoperative simulation of osteotomies in a visualized manner. However, the traditional cutting algorithm cannot meet the diverse demand of virtual osteotomies. This paper presents a prism cutting algorithm...
Distributed denial-of-service (DDoS) attack presents a very serious threat to the stability and security of the Internet. lt should be more efficient to detect the anomaly of network traffic firstly rather than to analyze the data packets directly. In this paper, an auto-adapted algorithm is proposed on the average value and threshold value of the network traffic which can make them to do auto-adaptations...
