Femtocells use common cellular air access technologies, but claim to improve system capacity according to Shannon's law by reducing distance between transmitter and receiver and thus improving the signal-to-noise ratio (SNR). Femtocells, however, use the IP Network as backhaul architecture instead of the conventional cellular network infrastructure. Thus,(More)
The term clustering refers to the identification of natural groups within a data set such that instances in the same group are more similar than instances in different groups. Evolutionary algorithms have a history of being applied into clustering analysis. However, most of the existing evolutionary clustering techniques fail to detect complex/spiral shaped(More)
In industr?, t o d q many producfs are soldfor their efficacy rather than their chemical composition. There are several key attributes within the coating industrv such as, Anchorage, Seal strength etc., which characterize the quality of the final product and are features used by the company to promote the sale of the product. Such qualify variables(More)
This paper presents a Spiking Neural Network (SNN) architecture for mobile robot navigation. The SNN contains 4 layers where dynamic synapses route information to the appropriate neurons in each layer and the neurons are modeled using the Leaky Integrate and Fire (LIF) model. The SNN learns by self-organizing its connectivity as new environmental conditions(More)
—This paper proposes a novel scheme of a Takagi-Sugeno (T-S) fuzzy based adaptive critic for the optimal control of the continuous-time input affine nonlinear system. A novel learning strategy is proposed to update the weights of critic network which resolves the issue of under-determined weight update equations discussed in [1]. The T-S Fuzzy based critic(More)
Security has always been an issue with 802.11 WLANs despite their massive deployment across the cities. EAP has been widely endorsed by many businesses as a more recent and robust security protocol. This paper evaluates the delay incorporated by EAP-enabled WLAN APs when used from the outdoor environments. This evaluation is in relation with the performance(More)
—The limitations of conventional model-based control mechanisms for flexible manipulator systems have stimulated the development of intelligent control mechanisms incorporating fuzzy logic and neural networks. Problems have been encountered in applying the traditional PD-, PI-, and PID-type fuzzy controllers to flexible-link manipulators. A PD-PI-type fuzzy(More)
