of a dissertation at the University of Miami. Dissertation supervised by Professor Miroslav Kubat. No. of pages in text. (108) Traditional classification techniques assume samples are described by vectors of features. However, in some domains samples are gathered by measuring a variable with respect to two or more other variables: for a given value of x and y measure z. In such domains, samples...

A generalization/specialization of the PARAFAC model is developed that improves its properties when applied to multi-way problems involving linearly dependent factors. Thismodel is called PARALIND (PARAllel profiles with LINear Dependences). Linear dependences can arise when the empirical sources of variation being modeled by factors are causally or logically linked during data generation, or c...

Dissolved organic matter (DOM) is a universal part of all aquatic systems that largely originates with the decay of plant and animal tissue. Its polyelectrolytic and heterogeneous characters make it an effective metal-complexing agent with highly diverse characteristics. Microbes utilize DOM as a source of nutrients and energy and their enzymatic activity may change its composition, thereby alt...

The simultaneous determination of two carbamate pesticides (carbaryl and carbendazim) and of the degradation product of carbaryl (1-naphthol) in iceberg lettuce was achieved by means of PARAFAC decomposition and excitation-emission fluorescence matrices. A standard addition method for a calibration based on four-way data was applied using different dilutions of the extract from iceberg lettuce ...

We present a novel multidimensional seismic trace interpolator that works on constant-frequency slices. It performs completion on Hankel tensors whose order is twice the number of spatial dimensions. Completion is done by fitting a PARAFAC model using an Alternating Least Squares algorithm. The new interpolator runs quickly and can better handle large gaps and high sparsity than existing comple...

Abstract Obtaining channel status information (CSI) is one of the main problems intelligent reflective surface (IRS) assisted communication system. This because IRS has only a large number passive components and cannot process signals. In this paper, we aim to estimate downlink multi-user multiple-input multiple-output (MU-MIMO) time division duplex (TDD) mode, estimated according uplink pilot ...

Abstract Background Most particulate organic matter (POM) cannot be directly degraded in the conventional wastewater treatment, which should transformed into dissolved (DOM) through a hydrolysis process. However, non-hydrolyzed POM biological treatment can limit treated efficiencies for plants (WWTPs) facilities. Hence an operational tool is indispensable insight removals of DOM and factions WW...
