Digital libraries： A testbed for multimedia technology

INTRODUCTION One of the greatest attractions of a digital library is its multimedia resources humans can use for informa- tion retrieval to knowledge discovery and information integration. A problem of multimedia researchers is to find a so-called killer-Apps which can demonstrate well the potentials of research topics such as video sum- marization, semantic annotation, multimedia cross indexing and retrieval, etc. Deeper research and wider ap- plications of digital libraries revealed the…

Integrating digital literacies and scientific communication in a multimedia anatomy group assignment to advance contextual learning

Anatomists are facing a new generation of learners who will study and work in a technology-rich environment. Indeed, digital technologies are tremendously changing how information and knowledge are communicated and retrieved. However, it remains unclear whether an anatomy assessment can be designed to promote contextual learning through integrating a digital communication strategy. To investigate this, assessment methods were diversified in the first-year neuroanatomy and third-year regional anatomy curricula through implementing a multimedia human anatomy group assignment integrating digital literacies and scientific communication. Through completing this multimedia assignment, students demonstrated their anatomy knowledge transfer using a range of approaches. The main mode of presentations chosen in the two anatomy units were non-animated video presentations (~50%), animated video presentations (~30%), storyboards (~10%), podcasts (~3%), and filmed videos (~3%). A 5-point Likert scale learning and teaching survey was conducted for a total of 195 undergraduate health science students to evaluate students' perception of this group assignment. The majority of students (70–80%) strongly agreed or agreed that the multimedia group assignment helped their teamwork skills. Students who produced animated videos significantly outperformed those who adopted the non-animated presentations during the end-of-semester theory examination (p < 0.05). This study demonstrates that an anatomy group assignment integrating digital literacy and scientific communication is an effective assessment strategy associated with a positive learning experience and outcome. This inquiry-based assignment promotes learning through assessment, allowing students to not only consolidate and extend anatomy knowledge but also developing effective digital communication skills, providing new insights into non-didactic anatomy assessments.

多媒体传输中基于可变权重的最少连接优先算法

Under high loads, a multimedia cluster server can serve many hundreds of connections concurrently, where a load balancer distributes the incoming connection request to each node according to a preset algorithm. Among existing scheduling algorithms, round-Robin and least-connection do not take into account the difference of service capability of each node and improved algorithms such as weighted round-Robin and weighted least-connection. They also do not consider the fact that the ratio of number of TCP connections
