Optimal control of wave-induced vibrations in semisubmersible structures with flexible superstructures
… the wave energy is distributed according to a Rayleigh distribution. Because mass and damping terms vary with the frequency of the wave motion, there is an infinite number of sets of dynamical equations, one for each frequency in the Rayleigh distribution. Practical considerations make it …

An improved code rate search scheme for adaptive multicode CDMA
… We also build a multipath fading channel with Rayleigh distribution. In the design of the channel model, our focus is given to the description of Doppler filter which is the essential part of the channel model.

Theoretical Properties and Estimation In Weighted Weibull and Related Distributions
The Weibull distribution is a well known and common distribution. In this thesis, theoretical properties of weighted Weibull distributions are presented. Properties of the non-weighted Weibull distribution are also reiterated for comparison. The probability density functions, cumulative …

Techniques for examining the statistical and power spectral properties of random time histories
… analyzed to determine their mean and amplitude distributions. It was found that the distribution of means could be approximated by a normal distribution and that the distribution of amplitudes could be approximated by the sum of a Rayleigh distribution and a normal distribution. An attempt was …

Non-Rayleigh scattering by a randomly oriented elongated scatterer
… false alarm (PFA) are shown to be strongly non-Rayleigh and a strong function of shape of scatterer. The tails are shown to increase above that associated with a Rayleigh distribution with increasing degree of elongation (aspect ratio) of the scatterer and when roughness effects are introduced. …

Amplitude resolution by human and ideal observers for Rayleigh noise and other Gaussian processes
… amplitude on any trial was drawn from one of two Rayleigh probability distributions that differed in mean amplitude. Similarly, the amplitudes of the narrow-band noises were distributed as the Rayleigh distribution by virtue of the reciprocal relation between their bandwidth (100 Hz centred on …

Weighted Generalization of Rayleigh and Related Class of Distributions
<p>Weighted distributions occur naturally and frequently in research related to reliability, bio-medicine, ecology and in the modeling of clustered sample, heterogeneity, and extraneous variation. In the analysis of intervention data, the expected value of the duration to completion of a random …

Simulation of an Anti-Collision Algorithm for RFID Systems using a Code Division Multiple Access with Adaptive Interference Cancellation (CDMA/AIC) Approach with Dynamic Processing Gain (Gp)
Radio Frequency Identification (RFID) Systems are modern wireless communication systems that transmit information from a transponder (tag) to a reader. RFID systems are well known because of their contactless feature. However, tag performance is limited by collision problems when multiple tags …
