Molecular structure modifications of camel milk (CaM) and cow (CM) mixtures during coagulation were investigated combining mid-infrared (MIR) spectroscopic monitoring with Parallel Factor Analysis (PARAFAC) particle-size measurements. To evaluate the evolution at molecular level, five different formulations prepared using following volume fractions CaM in mixtures: 100, 75, 50, 25, 0. Regarding...

In this study, the direct determination of cefixime as an anti-bacterial agent, in pharmaceutical formulations, urine and human blood plasma was conducted based on spectrophotometric measurements using parallel factor analysis (PARAFAC) and partial least squares (PLS). The calibration set was composed of fourteen solutions in the range of 0.50- 9.00 µg mL-1. PLS models were calculated at each p...

The Candecomp/PARAFAC decomposition (CPD) is an important mathematical tool used in several fields of application. Yet, its computation is usually performed with iterative methods which are subject to reaching local minima and to exhibiting slow convergence. In some practical contexts, the data tensors of interest admit decompositions constituted by matrix factors with particular structure. Oft...

Three-dimensional fluorescence is currently studied by methods such as parallel factor analysis (PARAFAC), regional integration (FRI), and principal component (PCA). There are also many studies combining convolutional neural networks at present, but there no one method recognized the most effective among 3D analysis. Based on this, we took some samples from actual environment for measuring data...

Abstract Improving the removal of micropollutants from wastewater effluent is crucial to protect surface water quality. This can be achieved by applying adsorption granular activated carbon. However, carbon filters used for treatment have a shorter lifetime than drinking production. It was assessed whether this related exclusively higher organic matter concentration in effluent, compared water,...

In this paper, we study the joint range and angle estimation problem based in monostatic frequency diverse-array multiple-input multiple-output (FDA-MIMO) radar, propose a method for base on compressed unitary parallel factor (PARAFAC). First, received complex signal matrix is stacked into third-order tensor. Then, can transform obtained tensor real-valued by employing forward–backward transfor...
