In view of the navigation problem of mobile robot in unknown dynamic environment, this paper proposes a new method of robot rolling navigation using improved ant colony system algorithm. The method first utilize the fuzzy logistic descr iption to es
This paper employs the propagator method (PM) to find the two-dimensional (2-D) direction of arrival angles (DOAs). Also the proposed algorithm can be applied to the situation when the incident sources are mixed either with uncorrelated or fully cor
We consider a wireless provider who caters to two classes of customers, namely primary and secondary users. Primary users have long term contracts while secondary users are admitted and priced according to current availability of excess spectrum. Se
