Monitoring, control and improvement of quality are  important  for companies.  Process capability indices (PCIs) are tools widely used by the industries to determine  the quality of their products and the performance of their manufacturing processes. Classic versions of  these  indices were constructed for processes whose quality characteristics have  a  normal distribution. But, many of these ...

[1] The planform of sublithospheric convection is studied by a 3-D linear stability analysis of longitudinal rolls in the presence of vertical shear. Rayleigh numbers up to 10 are considered. The transition Rayleigh number over which longitudinal rolls are unstable is derived as a function of surface velocity. Effects of nonlinear vertical shear are shown to be insignificant unless nonlinearity...

We study the super-resolution (SR) problem of recovering point sources consisting of a collection of isolated and suitably separated spikes from only the low frequency measurements. If the peak separation is above a factor in (1, 2) of the Rayleigh length (physical resolution limit), L1 minimization is guaranteed to recover such sparse signals. However, below such critical length scale, especia...

In this chapter, we are interested in the ultimate limit on the rate of reliable communication over Rayleigh-fading channels that satisfy the wide-sense stationary (WSS) and uncorrelated scattering (US) assumptions and are underspread [Bel63, Ken69]. Therefore, the natural setting is an information-theoretic one, and the performance metric is channel capacity [CT91, Gal68]. The family of Raylei...

Breast cancer is one of the most common cancers worldwide. In developed countries, among one in eight women develop breast cancer at some stage of their life. Early diagnosis of breast cancer plays a very important role in treatment of the disease. With the goal of identifying genes that are more correlated with the prognosis of breast cancer. An algorithm based on Trapezoidal and Rayleigh dist...

Specifying a proper statistical model to represent asymmetric lifetime data with high kurtosis is an open problem. In this paper, the three-parameter, modified, slashed, generalized Rayleigh family of distributions proposed. Its structural properties are studied: stochastic representation, probability density function, hazard rate moments and estimation parameters via maximum likelihood methods...

This paper deals with the propagation of magneto-thermo Rayleigh waves in a homogeneous viscoelastic half-space under initial stress. It has been observed that velocity of Rayleigh waves depends on viscosity, magnetic field, temperature and initial stress of the half-space. The frequency equation for Rayleigh waves under the effect of magnetic field, stress and temperature for both viscoelastic...

In this study, signal voltage obtained at the receiver is investigated by taking the Rayleigh Probability Density Function into account. Probability of received signal and occurrence of incoming signal between two levels are also studied. Success percentage, requirement of how much the receiver is to be modified and variation of voltage or power at the output with respect to time are simulated ...

—In this paper, symbol-error-rate (SER) performance analysis is provided for hybrid cooperation (HC) system in an asymmetric fading environment where the source-to-relay and the relay-to-destination channels experience independent Rayleigh/Rician and Rician/Rayleigh fading, respectively, while the direct channel link between the source and the destination is subject to Rayleigh fading. Unlike ...

Natural convection heat transfer was investigated experimentally in a concentric-cylinders annulus. To enhance the rate of heat transfer, pin fins were installed on the surface of the inner cylinder. Two fin arrangements were employed, namely, staggered and in-line arrangements. The length of the fins varied from 2 to 8 cm and the Rayleigh number Ra changed in the range from 5 x 105  to 5 x 106...
