Energetics and vibrational analysis study of six isomers methyl salicylate in their singlet ground state first excited triple is put forward this work at the density functional theory level large basis sets. The ketoB isomer lowest energy isomer, followed by its rotamer ketoA. For both ketoA enolized tautomers are found to be stable as well open forms that lack internal hydrogen bond. calculated spectra excellent agreement with IR experiments vapor phase. It demonstrated solvent effects have...
Ubiquitous low cost multi-rotor and fixed wing drones or unmanned aerial vehicles (UAVs) have accelerated the need for reliable, robust, scalable Structure-from-Motion (SfM) Multi-View Stereo (MVS) pipelines suitable a variety of flightpath trajectories especially in degraded environments. Feature tracking being core part SfM MVS, is essential multiview scene modeling perception, but difficult to evaluate large scale datasets due lack sufficient ground-truth. For large-scale imagery,...
The photophysics of methyl salicylate (MS) isomers has been studied using time-dependent density functional theory and large basis sets. First electronic singlet triplet excited states energies, structure, vibrational analysis were calculated for the ketoB, enol, ketoA isomers. It is demonstrated that photochemical pathway involving state intramolecular proton transfer (ESIPT) from ketoB to enol tautomer agrees well with dual fluorescence in near-UV (from ketoB) blue enol) wavelengths...
Abstract. Topographic Light Detection and Ranging (LiDAR) technology has advanced greatly in the past decade. Pulse repetition rates of terrestrial airborne systems havemultiplied thus vastly increasing data acquisition rates. Geiger-mode FLASH LiDAR have also become far more mature technologies. However, a new relatively unknown is maturing rapidly: Frequency-Modulated Continuous Wave Laser (FMCW-LADAR). Possessing attributes akin to modern radar systems, FMCWLADAR ability finely resolve...
Our research focuses on the Army's need for improved detection and characterization of targets beneath forest canopy. By investigating integration canopy characteristics with emerging remote data collection methods, foliage penetration-based target can be greatly improved. The objective our was to empirically model effect pulse return frequency (PRF) flight heading/orientation success penetration (FOPEN) from LIDAR airborne sensors. quantifying structure understory light we were able improve...
An in situ mesopourous surface imprinted polymeric (SIP) sensor was synthesized for a highly sensitive, selective, and kinetically faster detection of the high-vapor-pressure nerve gas surrogate methyl salicylate (MES). Visual occurred on filtrate thin films at 25 pM. Other surrogates, TP, DMP, DMMP, PMP, 1,4-thioxane, were tested showed decrease sensitivity compared to MES. In addition, 2,6-dipicolinic acid (DPA), biological indicator, also investigated Finally, plateau reached 40 s 1.5 ×...
With the rapid advancement of miniaturized sensors and unmanned airborne system (UAS) platforms, scientific measurements that previously were carried out by large government or academic institution programs can now be successfully accomplished smaller collection activities. In case vegetation assessment (e.g., forestry agriculture), spatial, temporal, radiometric, spectral resolution rigorously controlled. Although each these is important, accurate temporal chemistry morphological plant...
Herein we purpose to utilize upconverting phosphors detect explosives. To TNT, antibodies specific TNT are conjugated the surface. The role of is two fold; bind a quencher and accept TNT. bifunctional molecule, with one end containing analog other being dark fluorescent quenching dye. dye chosen so that luminescence from phosphor will be absorbed preventing it emitting, reducing phosphor. However, in presence bound DNT displaced. With displaced able emit light indicating present select area.
We report progress toward the development of a compression schema suitable for use in Army's Common Operating Environment (COE) tactical network. The COE facilitates dissemination information across all Warfighter echelons through establishment data standards and networking methods that coordinate readout control multitude sensors common operating environment. When integrated with robust geospatial mapping functionality, enables force tracking, remote surveillance, heightened situational...
