We present an observational and theoretical study of the optical emission from nonradiative shocks in three supernova remnants: the Cygnus Loop, RCW 86 and Tycho. The spectra of these shocks are dominated by collisionally excited hydrogen Balmer lines which have both a broad component caused by proton-neutral charge exchange and a narrow component caused by(More)
—Enabling 3D video in e-health applications results in the provision of more natural viewing conditions and improved diagnosis. Recent advances in wireless communications, network technologies and 3D video capture/display mechanisms enable the replacement of 2D video applications of current healthcare services with 3D video, to provide improved perception(More)
We present first results from an extensive survey of Magellanic Clouds super-nova remnants (SNRs) with the Spitzer Space Telescope. None was detected in the four short-wavelength IRAC bands, but all four were clearly imaged at 24 µm, and two at 70 µm. A comparison of these images to Chandra broadband X-ray images shows a clear association with the blast(More)
We report results from high resolution optical spectroscopy of three non-radiative galactic supernova remnants, RCW 86, Kepler's supernova remnant and SN 1006. We have measured the narrow component Hα line widths in Balmer-dominated filaments in RCW 86 and SN 1006, as well as the narrow component width in a Balmer-dominated knot in Kepler's SNR. The narrow(More)
—3D medical video was forecasted to be one of the groundbreaking 3D video applications. These range from tele-consultation to 3D robotics surgery. Enabling 3D video in e-health applications results in the provision of more natural viewing conditions, improved diagnosis and accurate interventions in surgical procedures. The deployment of 3D video services in(More)
