A Method for Measuring Television Random Noise by Sampling

Using a novel method for random noise reduction of seismic records

Random or incoherent noise is an important type of seismic noise, which can seriously affect the quality of the data. Therefore, decreasing the level of this category of noises is necessary for increasing the signal-to-noise ratio (SNR) of seismic records. Random noises and other events overlap each other in time domain, which makes it difficult to attenuate them from seismic records. In this r...

A Perfect Sampling Method for Exponential Family Random Graph Models

Generation of deviates from random graph models with non-trivial edge dependence is an increasingly important problem. Here, we introduce a method which allows perfect sampling from random graph models in exponential family form (“exponential family random graph” models), using a variant of Coupling From The Past. We illustrate the use of the method via an application to the Markov graphs, a fa...

A Perfect Sampling Method for Exponential Random Graph Models

Recording 2-D Nutation NQR Spectra by Random Sampling Method

The method of random sampling was introduced for the first time in the nutation nuclear quadrupole resonance (NQR) spectroscopy where the nutation spectra show characteristic singularities in the form of shoulders. The analytic formulae for complex two-dimensional (2-D) nutation NQR spectra (I = 3/2) were obtained and the condition for resolving the spectral singularities for small values of an...

A New Method for Measuring the Angle of Hallux Valgus

Objectives. The aim of this study is to introduce a new way and assign its reliability and validity in measuring the angle of hallux valgus. Methods. In this method, we have proceeded to introduce a simple way for measuring the angle of hallux valgus by using ruler and mathematical formulas. For doing this study, we selected 25students and measured their angle of hallux valgus with new way ...
