■ Hyperspectral imaging sensors are used to detect and identify diverse surface materials, topographical features, and geological features. Because the intervening atmosphere poses an obstacle to the retrieval of surface reflectance data, algorithms exist to compensate the measured signal for the effects of the atmosphere. This article provides an overview and an evaluation of available atmosph...

In this study the effect of using multi-walled carbon nanotube (MWCNT) on flexural and compressive strengths, ultimate displacement and energy absorption capability of standard cement mortar considering different weight percentages of nanotubes as well as different dispersion methods has been investigated. Influential point in adding nanotubes to the composites is their proper dispersion, which...

We propose and discuss two information-based measures of statistical dispersion of positive continuous random variables: the entropy-based dispersion and Fisher information-based dispersion. Although standard deviation is the most frequently employed dispersion measure, we show, that it is not well suited to quantify some aspects that are often expected intuitively, such as the degree of random...

With the development of high-speed, longdistance optical fiber communication systems, single-mode fiber polarization mode dispersion (PMD: Polarization mode dispersion) becomes one of the important factor limiting high-speed, long-distance optical fiber transmission. Polarization mode dispersion can cause pulse broadening in thedigital transmission system, result inter-symbol interference in di...

Model of laminated wave turbulence allows to study statistical and discrete layers of turbulence in the frame of the same model. Statistical layer is described by Zakharov-Kolmogorov energy spectra in the case of irrational enough dispersion function. Discrete layer is covered by some system(s) of Diophantine equations while their form is determined by wave dispersion function. This presents a ...

We developed an analytical relationship between nuclear magnetic relaxation and interparticle spacings in polymer nanocomposites filled with paramagnetic-impurity-containing clay nanoparticles. Using (1)H NMR relaxometry, clay nanoparticle dispersion was quantified and agrees with interparticle spacing distributions determined from statistical analysis of TEM images. Some information on the ove...
