We consider how to represent the measurable sets in an infinite measure space. We use sequences of simple measurable sets converging under metrics to represent general measurable sets. Then we study the computability of the measure and the set operators of measurable sets with respect to such representations. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) 相似文献

Computability of measurable sets via effective topologies 总被引:1,自引:0,他引:1
We investigate in the frame of TTE the computability of functions of the measurable sets from an infinite computable measure
space such as the measure and the four kinds of set operations. We first present a series of undecidability and incomputability
results about measurable sets. Then we construct several examples of computable topological spaces from the abstract infinite
computable measure space, and analyze the computability of the considered functions via respectively each of the standard
representations of the computable topological spaces constructed.

针对水平方向地电极电流场无线强穿透信息传输需求,研究了基于极低频水平双电极电流场信道传输特性。考虑到电极半径、电极入土深度、电极间距、发射信号频率和信号传输距离等参数对透地(Through-The-Earth, TTE)通信传输性能的影响,建立了地电极电流场TTE通信路径损耗模型,分析了各参数对路径损耗的影响,确定了信号传输最佳工作参数。根据选定参数搭建了极低频电流场TTE通信系统,在200 m和400 m通信距离下测试了3~10 Hz信号的路径损耗,通过试验数据与仿真结果对比分析验证了模型的准确性。 相似文献
