Data Analysis using Riemannian Geometry and Applications to Chemical Engineering [PDF]

open access: yesarXiv, 2022
We explore the use of tools from Riemannian geometry for the analysis of symmetric positive definite matrices (SPD). An SPD matrix is a versatile data representation that is commonly used in chemical engineering (e.g., covariance/correlation/Hessian matrices and images) and powerful techniques are available for its analysis (e.g., principal component ...

Three-dimensionally confined diluted magnetic semiconductor clusters. Zn1−xMnxS [PDF]

open access: yes, 1991
We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters of not, vert, similar 25 Å diameter are successfully synthesized inside a glass matrix and fully characterized

Synthesis and characterization of hybrid organic-inorganic materials based on sulphonated polyamideimide and silica [PDF]

open access: yes, 2010
The preparation of hybrid organic–inorganic membrane materials based on a sulphonated polyamideimide resin and silica filler has been studied. The method allows the sol–gel process to proceed in the presence of a high molecular weight polyamideimide,

Antireflection Surfaces for Biological Analysis Using Laser Desorption Ionization Mass Spectrometry

open access: yesResearch, 2018
Laser desorption ionization mass spectrometry (LDI-MS) is a primary tool for biological analysis. Its success relies on the use of chemical matrices that facilitate soft desorption and ionization of the biomolecules, which, however, also limits its ...

SOURCE IDENTIFICATION OF ENVIRONMENTAL POLLUTANTS USING CHEMICAL ANALYSIS AND POSITIVE MATRIX FACTORIZATION [PDF]

open access: yes, 2012
Multivariate modeling techniques are successfully used in different areas of environmental research because of their ability to process large data sets. The main objective of their application lies in the determination of data structures and hidden information which account for the data set variability. This thesis work seeks to explore the application
