1. Vibrational Spectroscopy and Chemometrics in Forensic Chemistry: Critical Review, Current Trends and Challenges
The present manuscript makes an extensive review of the scientific approaches developed in the last decade involving infrared and Raman spectroscopy combined with chemometrics for solving several issues in the investigation of the most relevant forensic traces, such as questioned documents and currency, explosives, gunshot residues, illicit drugs and body fl

2. AVALIAÇÃO DE ESPECTRÔMETRO NIR PORTÁTIL E PLS-DA PARA A DISCRIMINAÇÃO DE SEIS ESPÉCIES SIMILARES DE MADEIRAS AMAZÔNICAS
Supervising wood exploitation can be very challenging due to the existence of many similar species and the reduced number of wood identification experts to meet the demand. There is evidence that valuable endangered wood species are being smuggled disguised as other species. Near infrared spectroscopy (NIRS) and chemometrics has been successfully used to dis

3. Influencia do posicionamento e da largura de bandas de sensores remotos e dos efeitos atmosfericos na determinacao de indices de vegetacao / Influence of remote sensor band positioning and bandwidth and atmospheric efects on the vegetation index determinations
Investigou-se a influencia do posicionamento e da largura das bandas do Vermelho (V - 600 a 700 nm)e do Infravermelho proximo (IVP - 750 a 1100 nm), assim como a influencia da atmosfera, na determinacao dos indices de vegetacao (IVs)NDVI, SAVI e ARVI, obtidos a partir de dados hiperespectrais do sensor Airborne Visible/InfraRed Imaging Spectrometer (AVIRIS).
