Mid-Infrared Spectral Characterization of Aflatoxin Contamination in Peanuts
… paste samples, was investigated, in terms of spectral characteristics using FTIR-ATR. The effects of spectral pre-processing steps such as mean-centering, smoothing the 1st derivative and normalizing were studied. Logarithmic method was the best normalization technique describing the …

Optical Tracking and Spectral Characterization of Cubesats for Operational Missions
… is, but what the object is. The optical and spectral characteristics of solar light reflected off of satellites or debris can provide information on the physical state or identity of the object. These same optical signatures can be used for mission support of operational satellite missions- …

Spectral characterization of desert surfaces in Kuwait by satellite data
… a study was necessary to characterize their spectral signatures as detected by Landsat Thematic Mapper (TM) data. A sophisticated image analysis was applied to the Landsat TM scene. An unsupervised classification technique produced a thematic map of the area. Data was collected on the ground …

Spectral characterization of actinide signatures for nuclear remote sensing applications
… potential devices. This dissertation focuses on spectral signatures that may be generated from the actinide material and strongly emitting fission products in a nuclear fireball free from the interference of high explosives and engineering materials that may be present in the fireball produced …

Physical-chemical treatment of landfill leachate : technological performance, spectral characterization and cost estimations
… leachate treatment train. The research also used spectral and chemometric techniques to characterize dissolved organic matter (DOM) components in landfill leachate and to monitor how they are removed during treatment. The results show that (post)-treatment of raw and biologically treated leachate …

Top-Down Proteomics: Separation and Mass Spectral Characterization of Complex Cell Lysates From Methanosarcina Acetivorans and Human Cancer Cells
The combination of nano-LC-MS/MS with an online-offline automation platform and an iterative data search strategy has allowed for high-throughput data acquisition to be possible with top-down protein analysis. Taken together, these platforms represent the next step in increasing the utility of …

Optoperforation of Intact Plant Cells, Spectral Characterization of Alloy Disorder in InAsP Alloy Disorder in InAsP Alloys, and Bimetallic Concentric Surfaces for Metal-Enhanced Fluorescence in Upconverting Nanocrystals
The techniques of optoperforation, spectral characterization of alloy disorder, and metal-enhanced fluorescence were applied to previously unconsidered or disregarded systems in order to demonstrate that such applications are both feasible and consequential. These applications were the subject of …

EVOLUTION AND CHARACTERIZATION OF A NEW REVERSIBLY PHOTOSWITCHABLE CHROMOPROTEIN
We report the molecular engineering and spectral characterization of a new reversibly photoswitchable chromoprotein, B11 a variant of thermostable green protein (TGP) that has been evolved for favorable solubility, thermostability, and enhanced crystallization properties. Its 2.5 \xc5 joint X-ray …

Characterization of spectral response of a quantum dots-in-a-well infrared focal plane array
Spectral characterization of a novel single bump, two-color InAs/InGaAs quantum dots-in-a-well (DWELL) infrared focal plane array (FPA) was undertaken and reported here. The hypothesis of the study is that the FPA will exhibit bias-tunable spectral response. Broadband and two-color performance …

Existence and Stability of Solitary Waves for NLS with Defects
… we provide a complete classification of their spectral stability. Finally, we show that the waves are non-degenerate and consequently orbitally stable, whenever they are spectrally stable. Incidentally, our construction shows that the soliton profiles for the concentrated NLS are in fact exact …
