satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

A new technique, the spectral response of the steady-state photoconductance, is proposed for solar cell characterization in research and development. The method is experimentally demonstrated with solar cell precursors having emitters with markedly different levels of surface and bulk recombination losses. A highefficiency solar cell has been investigated, comparing the new spectral response me...

seismic ground motion is profoundly affected by geometrical and mechanical properties of soil deposits overlaying bedrock. local seismic ground response of saturated soil deposits was studied in literature by applying the effects of soil stress state and index properties on the strain-dependent normalized shear modulus reduction, g/g0, and damping ratio, d, curves in an equivalent linear analys...

based on the standards for design of structures, any structure should be designated for seismic loads and any combinations containing seismic loads. for spectral analysis of a structure, the site effect is taken into account by considering its effects on the design spectra. because of different lateral and vertical stiffness of the soil layers underneath the structure, the design spectra are di...

This letter presents a novel multi-carrier code division multiple access (MC-CDMA) system called time domain synchronous MC-CDMA (TDS-MC-CDMA). Aided by the new training sequence (TS) with perfect autocorrelation in the time domain and flat frequency response in the frequency domain, the proposed TDS-MC-CDMA system outperform the traditional MC-CDMA system in terms of spectrum efficiency by abo...

The Frequency Response Function (FRF) of a nonlinear system under white Gaussian ezcitation is computed up to O(P2) in the power spectral density of the input P. The FRF qualitatively shows the ezpected shifts in resonant frequency and supports the observed fact that FRFs from fandam excitation are returned as lkar system FRFs by the Hzlbert transform test.
