The overall objective of this study was to use field spectro-radiometers for finding possible spectral regions in which chlorophyll-a (Chl-a) and particulate organic carbon (POC) could be identified so as to assist the assessment and monitoring of water quality using satellite remote sensing technology. This paper presents the methodology adopted in this study which is based on the application ...

Tm-doped TiO2 nanoparticles were synthesized using a water-controlled hydrolysis reaction. Analysis was performed in order to determine the influence of the dopant concentration and annealing temperature on the phase, crystallinity, and electronic and optical properties of the resulting material. Various characterization techniques were utilized such as X-ray diffraction, Raman spectroscopy, X-...

The advantages of Hyperspectral Imaging (HSI) over conventional remote sensing imaging has been well recognized (Schowengerdt, 1983). HSI provides the user with spatial and spectral information about scene objects and facilitates improved detection and identification over panchromatic and multispectral imagery. The predecessors of present day HSI systems were the broad band spaceborne multi-spe...

Quantification of RCA phylotypes We developed a specific PCR approach to estimate the abundance of the RCA phylotypes relative to total bacterial 16S rRNA genes based on serial dilution of extracted DNA. Alternate 1:5 and 1:2 dilution steps to extinction were applied in triplicates, to 10-fold dilution or higher. PCRs with bacterial and RCA-specific primers were performed simultaneously using 6...

Utilization of the digital Landsat TM bands for automatic lineaments extraction and selection of the optimum bands are the main objects of this article. The classical method for lineament extraction was manually performed through aerial photographs and satellite imagery. Nowadays several commercial softwares are developed to deal with the automatic linear features extraction using the optical a...

We have tested our encoding generated by TM-LPSAT compiler on a number of problems of varying complexity and characteristics, using different SATbased arithmetic constraint solvers. The intention of the experiments 1 was to observe the feasibility of our encoding, the scalability of this approach in temporal metric domains, and how features of different constraint solvers react with characteris...

Thermal infrared remote sensing data are used to make estimates of the land surface temperature (LST) by recording radiant energy emitted Earth. Satellite and image processing software also allow for LST estimation. Since its launch, two thermal bands aboard Landsat satellite have been continuously observe Earth, providing estimation normalized difference vegetation index (NDVI). Due significan...

The optical absorptivities of oriented single crystals of hcp Gd, Tb, Dy, Ho, Er, Tm, and Lu were measured at 4.2 K between 0.2 and 4.4 eV. Polarized radiation was used to reveal the optical anisotropy. Systematic movement of structures in the absorptivity and optical conductivity was observed as a result of trends within sp and d bands. Low-energy structures were related to effects of s−f exch...
