This paper introduces an adaptive Radial Basis Function (RBF) method using weighted improvement for the global optimization of black-box problems subject to box constraints. The proposed method applies rank-one update to efficiently build RBF models and derives a closed form for the leave-one-out cross validation (LOOCV) error of RBF models, allowing an adaptive choice of radial basis functions. In...
In this paper, we analyze the performance of time delay estimation with regards to different pulse shape in UWB indoor navigation. For the performance of time delay estimation, the Cramer-Rao Lower Bound (CRLB) criterion is used and the performance is analyzed under various criteria of pulse shape, such as pulse period, order of differentiation, and the effective pulse width. Moreover, the reasonability...
This paper investigates a two stage equilibrium model for generators' strategic behaviors in contract signing in the forward market and electricity bidding in the electricity spot market. We propose a linear asymmetric supply function equilibrium model to develop generators' optimal bidding strategies considering a forward market equilibrium in the second stage, and show the existence and uniqueness...
We propose a novel location finding system exploiting the downlink reference signal of the Long Term Evolution (LTE) because of the absence of an efficient location finding system for the LTE. The proposed system is based on the correlation method and Chan's method for location sensing and positioning process, respectively. The conventional correlation method, however, is not matched to the LTE since...
