In Dictionary Learning one is trying to recover incoherent matrices A∗ ∈ Rn×h (typically overcomplete and whose columns are assumed to be normalized) and sparse vectors x∗ ∈ R with a small support of size h for some 0 < p < 1 while being given access to observations y ∈ R where y = A∗x∗. In this work we undertake a rigorous analysis of the possibility that dictionary learning could be performed...

in this work, copper oxide nanoparticles have been synthesized via extractive rosmarinus officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (ch3coo)2cu+h2o individually as cu sources. it was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0c. powder x-ray diffrac...

The Modal Assurance Criterion (MAC) has been used for numerous years as a measure of correlation between test and analytical mode shapes. The fact that the MAC considers only mode shapes usually means that a separate frequency comparison must be used in conjunction with the MAC values to determine the correlated mode pairs. The mode shape correlation has generally been displayed as the MAC matr...

Our purpose was to measure simultaneous fluxes from soil of both N2O and N2 from the same plot in the field using the 15N-gas "nonequilibrium" technique (i.e., the "Hauck" technique) as used previously for N2. We accommodated analysis of N2O by modifying the head amplifier of our mass spectrometer. Our system accurately measured the 15N enrichments of labeled soil slurries for both N2 and N2O. ...

This paper presents a simple resistant estimator of multivariate location and dispersion. The DD plot is a plot of Mahalanobis distances from the classical estimator versus the distances from a resistant estimator and can be used to detect outliers and as a diagnostic for multivariate normality. The new estimator can be used in the DD plot, is easy to compute and provides insights about several...

INTRODUCTION A geostatistical approach to characterize MS-lesion patterns based on their geometrical properties is presented. METHODS A dataset of 259 binary MS-lesion masks in MNI space was subjected to directional variography. A model function was fit to express the observed spatial variability in x, y, z directions by the geostatistical parameters Range and Sill. RESULTS Parameters Range...
