In this paper, by using the way of weight coecients and technique of real analysis, a multidimensionaldiscrete Hilbert-type inequality with a best possible constant factor is given. The equivalentform, the operator expression with the norm are considered.

in this research, the effect of surface roughness and bubble injection on skin friction and hydrodynamic drag force has been numerically considered. this research is based on taylor-couette flow. considered flow includes two concentric cylinders which internal cylinder is movable and external is immovable. the effective equations on the flow includes: equations of momentum, continuous, turbulen...

We present methodology for identifying the most likely connguration of unobserved variables, given observed variables, for collections of discrete and continuous variables with conditional Gaussian (CG) distributions. The dependency structure on the joint distribution of discrete and continuous variables is represented in terms of a directed acyclic graph (DAG) in which continuous variables do ...

Discrete nanoparticles of MnAs with distinct magnetostructural properties have been prepared by small modifications of solution-phase arrested precipitation reactions. Rietveld and X-ray atomic pair distribution function based approaches were used to explore the evolution of the structure of the samples with temperature, and these data were compared to the magnetic response measured with ac sus...

In the continuous-time domain, Maximum-Likelihood (ML) detection of a chirp signal in white Gaussian noise can be done via the line-integral transform of the classical Wigner distribution. The line-integral transform is known variously as the Hough transform and the Radon transform. For discrete-time signals, the Wigner-type distribution defined by Claasen and Mecklenbrauker has become popular ...

The aim of this study is to investigate of the synchronization of periodic rhythmic movements with single discrete movements as reaction to external trigger signals. The underlying coordination principle derived from the experimental results is supposed to be either phase entrainment or phase reset. In phase entrainment, the response is more probable to occur during the phase, when the periodic...

Transmission of information over a discrete-time memoryless Rician fading channel is considered. The noncoherent scenario, where neither the receiver nor the transmitter knows the fading coefficients, is assumed. If the input is subject to a peak-power constraint, it is shown that uniformly distributed phase is optimal and the capacity-achieving amplitude distribution is discrete with a finite ...

A new alternative in the analysis of manufacturing systems with finite buffers is presented. We propose and study a new approach in order to build tractable phase–type distributions, which are required by state–of–the–art analytical models. Called “probability masses fitting” (PMF), the approach is quite simple: the probability masses on regular intervals are computed and aggregated on a single...
