In this paper, we present our Concurrent Systems class, where parallel programming and parallel and distributed computing (PDC) concepts have been taught for more than 20 years. Despite several rounds of changes in hardware, the class maintains its goals of allowing students to learn parallel computer organizations, studying parallel algorithms, and writing code to be able to run on parallel and distributed...
Stereo vision is an active research topic in computer vision. Point Grey® Bumblebee® and digital single-lens reflex camera (DSLR) are normally found in the stereo vision research, they are robust but expensive. Open source electronic prototyping platforms such as Arduino and Raspberry Pi are interesting products, which allows students or researchers to custom made inexpensive experimental equipment...
The abundant availability of multi-core computers makes "parallel computers" a common place and teaching Computer Science students to be able to design and develop parallel algorithms an urgent task. Most students recognize the needs of developing skills in parallel programming. However, since their Computer Science related curriculum are mostly taught based on sequential computers, introducing...
In hotspot areas, heavy traffic requires a large capacity of network systems. However, it leads to a waste of energy during idle periods. In this paper, we at first analyzed the traffic distribution of hotspots in a business center. We then discussed a novel scheme which applies self-optimization and self-configuration mechanisms to realize hibernation and wakeup of eNBs in 3GPP LTE-Advance networks...
Today, workflow based software model has become mainstream to many application system developments. However, in most of these applications, their workflow procedures are fixed in their source code, this is not only restricts to the enterprises changing their working procedures to adapting the market requirements, but also limits the dynamic changes, scalability and adaptation of the system itself...
The traditional method based on "support-confidence" framework could bring a large number of irrelevant or even misleading association rules. In view of the problem of evaluation standards of association rules, we increase interest measure in the evaluation standards, and give the definition of interest measure and positive and negative association rules method based on "interest-support-confidence"...
In Automatic Question Answering System, topic identification is usually based on relevancy computation of sentences. This paper introduces an approach to compute topic relevancy. Using the semantic computation in HowNet, the relevancy of sentences can be calculated. The topic relevancy of sentences can be calculated through the computation of relevancy between words of sentence and subject words....
CDIO is a new mode in modern engineering education distinguished from traditional modes, which is project-based. CDIO stands for conceiving, designing, implementing and operating. It has been proved effective in engineering education. After the steps of CDIO analyzed, an example using CDIO is presented to show how CDIO works, and how traditional courses are changed into CDIO courses as well. The experiments...
The knowledge representing method, question semantic analysis and answer extraction algorithm are very important parts of QA (question answering system). This paper puts forward a framework which can well serve not only the simple question, but also the complex conditional question; can construct and apply ontology to drive Chinese restricted domain QA; and can conveniently extract answer by QSR (question...
