Multi-polarized space borne SAR data can be used to detect changes in land cover. The ENVISAT ASAR has the ability to acquire images using two polarizations simultaneously. This paper discusses the capability of detecting land surface characteristics using ENVISAT ASAR dual polarization data. The applicability of image mode and alternative polarization mode(More)
Six cadmium(II) halide complexes with dl-piperidine-2-carboxylic acid (DL-Hpipe-2), dl-piperidine-3-carboxylic acid (DL-Hpipe-3), and piperidine-4-carboxylic acid (Hpipe-4), have been prepared and characterized by means of IR and Raman spectra and thermal analysis. The crystal structures of [CdCl2(DL-Hpipe-2)(H2O)], [CdBr2(DL-Hpipe-3)], and [CdCl2(Hpipe-4)](More)
A magnetic reproducing head using parametric oscillation has been developed for use in perpendicular magnetic recording. The head is based on parametric oscillation in a resonant circuit consisting of a single pole-type perpendicular magnetic recording head and four varactor diodes for time-variable capacitance. In this paper, the principle of data(More)
