It is a key problem to schedule the multiple unmanned ground vehicles and to achieve reliable target handover in an area needs to be continuously monitored. This research is concerned with the coordinated relay tracking of a moving target. Two relay tracking strategies are proposed. We first present the definition of the relay tracking. Then a relay tracking scheme based on UGV coverage is proposed...
This paper introduces the concept of data mining and its an important branch - association rules, describes the basic concept of association rules, the basic model of mining association rules, introduces the classical algorithm of association rules, and then classified discusses the association rules mining from several angles such as width, depth, partition, sampling and incremental updating. Finally,...
This paper introduces the concepts of data mining and focuses on the most important and commonly used method of association rules mining. Then association rule mining is applied to the related teaching activities, and some information and rules are got. Using this information can better predict teaching situation and assess teaching effectiveness.
With the development of modern education, and considering the shortcoming of current online exam system, a new projection of online exam system based on data mining is given, and the key implementation techniques and methods are also described.
To investigate changes in vascular functions in streptozotocin (STZ)-induced diabetic rats and the effect of interleukin-2 (IL-2), male Sprague-Dawley rats were randomly divided into a normal group, a diabetic control group, and diabetic groups treated with a low dose (5000 U/kg/d) or a high dose of IL-2 (50000 U/kg/d) for five weeks. Rats were injected with STZ (60 mg/kg, i.p.) to induce diabetes...
