Questioned Electronic Documents : Empirical Studies in Authorship Attribution
Forensic analysis of questioned electronic documents is very difficult, because the nature of the documents eliminates many kinds of informative differences. Recent work in authorship attribution demonstrates the practicality of analyzing documents based on authorial style, but the state of the art is confusing. Analyses are difficult to apply, little is known about type or rate of errors, and ...
متن کاملSpectroscopic and chemometric approaches to radiobiological analyses.
Vibrational spectroscopy is an attractive modality for the analysis of biological samples, providing a complete non-invasive acquisition of the biochemical fingerprint of the sample. It has been demonstrated that this data provides the means to assay multiple functional responses of a biological system at a spatial resolution as low as a micron within the sample. As the interaction of ionizing ...
متن کاملThe use of laser desorption/ionization mass spectrometry in the analysis of inks in questioned documents.
Determination of the age of a handwritten or ink printed questioned document can be an important consideration in forensic cases. Most often the age of a document is determined by the chemical behavior of the dyes that make up the ink. Exposure of the dyes to environmental factors such as oxygen and ultraviolet or visible light cause them to degrade. Often this degradation can be correlated to ...
متن کاملPhotoluminescence quantitative analysis of Gallic acid and Caffeine in green tea using multi-way chemometric approaches
Green tea is considered as a dietary source of antioxidant nutrients, which acts upon human health. Green tea leaves contain three main components in the form of simple hydroxy benzoic acids such as gallic acid, propyl gallate and xanthic bases (caffeine), have been reported to prevent or delay a number of degenerative diseases and act mainly upon the central nervous system and stimulating wake...
