For each real number λ∈ [0, 1], λ-power distributional chaos has been in- troduced and studied via Furstenberg families recently. The chaoticity gets stronger and stronger as A varies from 1 to 0, where 1-power distributional chaos is exactly the usual distributional chaos. As a generalization of distributional n-chaos,λ-power distributional n-chaos is defined similarly. Lots of classic results on distributional chaos can be improved to be the versions of λ-power distributional n-chaos accordingly. A practical method for distinguishing 0-power distributional n-chaos is given. A transitive system is constructed to be 0-power distributionally n-chaotic but without any distributionally （n ＋ 1）-scrambled tuples. For each λ∈ [0, 1], ）,-power distributional n-chaos can still appear in minimal systems with zero topological entropy.

TELEMEDICINE NETWORK BASED ON CODE-DIVISION MULTIPLE ACCESS WIRELESS TECHNOLOGY

引用

Journal of Pharmaceutical Analysis 2003年第2期15卷 121-124,142页

作者：同鸣卞正中张亮 School of Life Science and Technology Xi’an Jiaotong University

Objective To satisfy the need of reliable and efficient telemedicine in many mobile and ambulance situations. Methods A practical telemedicine system bases on code division multiple access (CDMA) wireless communication technology has been developed, which has never been mentioned before. The design scheme for the proposed system is described and detailed analysis of the network protocol stacks and the data flow is presented. Results Experiments on real time transmission of medical images using developed system have demonstrated that the system performance is satisfactory and acceptable. Conclusion The telemedicine system based on CDMA is easy to implement and has high quality of transmitted images. It would be a prospective solution to mobile telemedicine.
