129 Furse, Cynthia M.Capacitance and inductance sensor circuits for detecting the lengths of open- and short-circuited wiresThe length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are introduced to measure these values. Open-circuited (capacitance) measurements are very effective.

133 Furse, Cynthia M.Impedance of a short dipole antenna in a magnetized plasma via a finite difference time domain modelThe traditional analytical analysis of plasma probes requires the use of quasi-static approximations, while numerical methods require the use of an equivalent dispersive media, both producing a nontrivial analysis of the plasma environment. On the other hand, a few techniques that combine the plasm...Antenna theory; finite-difference time-domain; FDTD; Plasma covered antennas; Plasma measurements2005-08
134 Tasdizen, Tolga; Whitaker, Ross T.Higher-order nonlinear priors for surface reconstructionAbstract-For surface reconstruction problems with noisy and incomplete range data, a Bayesian estimation approach can improve the overall quality of the surfaces. The Bayesian approach to surface estimation relies on a likelihood term, which ties the surface estimate to the input data, and the prior...2004
