: a new fibrous adsorbent was prepared by grafting acrylic acid /acryl amide (aa/aam) co-monomers onto poly(ethylene terephtalat) (pet) fibers. the resulting sorbent has been characterized by fourier transform infrared spectroscopy (ft-ir), thermo gravimetric analysis (tga), scanning electron microscopy (sem) and elemental analysis and studied for the preconcentration and determination of trace...

The profit of low-cost, multispectral imaging systems in estimating spectral power distributions has been widely studied. There are various mathematical methods available (PCA, Wiener’s estimation method, spline interpolation, MDST, among others) which permit the accurate reconstruction of a spectrum from the response of a small set of sensors. One important issue in this task is the influence ...

This paper provides a statistical investigation of the impact of heart rate levels on training effect for a specific exercise regimen, including an analysis of post-exercise heart rate recovery. Results indicate optimum target values for both average and maximum heart rate during exercise in order to improve both cardiorespiratory and cardiovascular fitness levels. The statistical methods used ...

We show that there are no spurious local minima in the non-convex factorized parametrization of low-rank matrixrecovery from incoherent linear measurements. With noisy measurements we show all local minima are very close to aglobal optimum. Together with a curvature bound at saddle points, this yields a polynomial time global convergenceguarantee for stochastic gradient descent ...

We describe a coupled experimental-numerical study of the effect of proton irradiation on the inductive turn-off of fastrecovery p-i-n diodes for snubberless applications. The goal is to avoid the large overvoltages and spurious oscillations that may arise at switch-off and jeopardize the diode’s reliability. We evaluated different proton irradiation profiles in order to extract indications on ...
