This paper applies the level crossing rate (LCR) and average fade duration (AFD) analysis to characterize clipping noise in filtered OFDM signals. Because orthogonal frequency division multiplexing (OFDM) signals exhibit complex Gaussian process behavior, well established results for the Rayleigh envelope of the correlated Gaussian process are used to(More)
Introduction Alzheimer’s disease (AD) is linked to increased brain deposition of amyloid-beta peptides in senile plaques. Successful visualization of amyloid deposits in the APP transgenic mouse brain with MR imaging has been reported by several investigators recently. However, there are very few reports of methods for the measurement of plaque burden in(More)
Introduction Alzheimer’s disease (AD) neuropathology is characterized by key features that include the deposition of the amyloid-beta peptides into senile plaques, the formation of neurofibrillary tangles, and the loss of neurons and synapses in specific brain regions. Here we report a measure of AD evolution based on the use of MR images of the APP(More)
This paper proposes a design of Artificial Bee Colony (ABC) algorithm based Proportional plus Integral controller using Area Requirement (AR) Criterion for the Load Frequency Control of a two area multi unit interconnected thermal reheat power system without and with Gas Turbine unit. The system was simulated and the output responses of the frequency(More)
