Anomaly identification during polymerase chain reaction for detecting SARS-cov-2 using artificial intelligence trained from simulated data
Villarreal-González, Reynaldo; Acosta-Hoyos, Antonio J.; Garzón-Ochoa, Jaime A.; Galán-Freyle, Nataly J.; Amar-Sepúlveda, Paola; Pacheco-Londoño, Leonardo C. (MDPIFacultad de Ingenierías, 2021)Real-time reverse transcription (RT) PCR is the gold standard for detecting Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), owing to its sensitivity and specificity, thereby meeting the demand for the rising ... -
Artificial intelligence assisted Mid-infrared laser spectroscopy in situ detection of petroleum in soils
Galán-Freyle, Nataly J.; Ospina-Castro, María L.; Medina-González, Alberto R.; Villarreal-González, Reynaldo; Hernández-Rivera, Samuel P.; Pacheco-Londoño, Leonardo C. (MDPI, 2020)A simple, remote-sensed method of detection of traces of petroleum in soil combining artificial intelligence (AI) with mid-infrared (MIR) laser spectroscopy is presented. A portable MIR quantum cascade laser (QCL) was ... -
Classical Least Squares Discriminant 1 Analysis of High Explosives Detected on Cotton Fabrics by Quantum Cascade Laser Spectroscopy
Pacheco-Londoño, Leonardo C.; Aparicio-Bolaños, Joaquín A.; Galán-Freyle, Nataly J.; Román-Ospino, Andrés; Hernandez, Samuel (Society for Applied Spectroscopy, 2017)Quantum cascade laser spectroscopy was used to detect the presence of residues of highly energetic materials (HEMs) on cotton fibers. The discrimination of the vibrational signals of HEMs from a highly mid-infrared (MIR) ... -
Classical Least Squares-Assisted Mid-Infrared (MIR) Laser Spectroscopy Detection of High Explosives on Fabrics
Pacheco-Londoño, Leonardo C.; Aparicio-Bolaño, Joaquín A.; Galán-Freyle, Nataly J.; Román-Ospino, Andrés D.; Ruiz-Caballero, Jose L.; Hernández-Rivera, Samuel P. (Society for Applied Spectroscopy, 2019)Mid-infrared (MIR) laser spectroscopy was used to detect the presence of residues of high explosives (HEs) on fabrics. The discrimination of the vibrational signals of HEs from a highly MIR-absorbing substrate was achieved ... -
Mid-Infrared laser spectroscopy detection and quantification of explosives in soils using multivariate analysis and artificial intelligence
Pacheco-Londoño, Leonardo C.; Warren, Eric; Galán-Freyle, Nataly J.; Villarreal-González, Reynaldo; Aparicio-Bolaño, Joaquín A.; Ospina-Castro, María L.; Shih, Wei-Chuan; Hernández-Rivera, Samuel P. (MDPIFacultad de Ingenierías, 2020)A tunable quantum cascade laser (QCL) spectrometer was used to develop methods for detecting and quantifying high explosives (HE) in soil based on multivariate analysis (MVA) and artificial intelligence (AI). For ... -
Modulated-laser source induction system for remote detection of infrared emissions of high explosives using laser-induced thermal emission
Galán-Freyle, Nataly J.; Pacheco-Londoño, Leonardo C.; Figueroa-Navedo, Amanda M.; Ortiz-Rivera, William; Castro-Suarez, John R.; Hernández-Rivera, Samuel P. (Optical Engineering, 2020)In a homeland security setting, the ability to detect explosives at a distance is a top security priority. Consequently, the development of remote, noncontact detection systems continues to represent a path forward. In ...
