In some applications of frequency estimation, it is challenging to sample at as high as Nyquist rate due to hardware limitations. Based on conventional ESPRIT, a new method for frequency estimation with double-channel sub-Nyquist sampling is proposed. When the two undersampled multiples are relatively prime integers, partial samples are selected to estimate the frequency components contained in...

The mixed variables-attributes test plans for single acceptance sampling are proposed to protect “good lots” from attributes aspect and to optimize sample sizes from variables aspect. For the single and double mixed plans, exact formulas of the operating characteristic and average sample number are developed for the exponential distribution. Numerical illustrations show that the mixed sampling ...

The two-phase sample design is often employed in sample surveys for various reasons. It has a long history, first introduced by Neyman (1938). Traditionally, the technique is used to collect some auxiliary data that are not available for the sampling frame from a large first-phase sample to use the data at the second-phase sampling. The technique, sometimes called “double sampling” has many app...

Introduction to Machine learning covering Statistical Inference (Bayes, EM, ML/MaxEnt duality), algebraic and spectral methods (PCA, LDA, CCA, Clustering), and PAC learning (the Formal model, VC dimension, Double Sampling theorem).

This paper describes a power spectrum analyzer whose bandwidth is not limited by the mean sampling time. The procedure is based on the estimation of the spectral components of the autocorrelation function of the input signal through the simultaneous random sampling of the given input signal and its randomly “delayed copy.” The samples are therefore randomly taken in a double-dimension space, ti...

Several importance sampling strategies are developed and tested for stereographic projection diffusion Monte Carlo in manifolds. We test a family of one parameter trial wavefunctions for variational Monte Carlo in stereographically projected manifolds which can be used to produce importance sampling. We use the double well potential in one dimensional Euclidean space to study systematically sam...

A double integrator is controlled by discontinuous-impulsive feedback with adaptation. The gain of the impulsive control is adapted to minimize the time convergence to zero of the double integrator dynamics when the impulsive control is applied. The real case is studied to take into account the limitation of the input amplitude, the sampling of the controller and the effect of the disturbances....

BACKGROUND The analgesic effect of oral sucrose in newborn infants undergoing painful procedures is generally accepted. For blood sampling, some studies have shown that venepuncture (VP) is less painful than heel lance (HL). OBJECTIVE To determine the least painful and most effective method among blood sampling by VP or HL with or without sucrose. DESIGN Randomised, double blind, placebo co...
