A two-dimensional, steady state model of the circle of Willis has been developed. To simulate the peripheral resistance of the cerebrovascular tree, blocks of porous media were used. Their effective resistance was kept constant, disregarding the effects of arterial auto-regulation. The model was then used to simulate different common abnormalities of the(More)
Single-phase magnetoelectric multiferroics are ferroelectric materials that display some form of magnetism. In addition, magnetic and ferroelectric order parameters are not independent of one another. Thus, the application of either an electric or magnetic field simultaneously alters both the electrical dipole configuration and the magnetic state of the(More)
A thermodynamic analysis of the electrocaloric ͑EC͒ effect in BaTiO 3 ferroelectric thin films has been carried out under differing mechanical boundary conditions. It is shown that both the magnitude of the electrocaloric effect and temperature at which it is maximized depend not only on the extent of the applied field change but also on the value of the(More)
This addendum documents change made to the ATBD between V2.0 and V3.0 of the Aquarius L2 salinity retrieval algorithm which was implemented in January, 2014 and that will be released to the public through the JPL PO.DAAC in March, 2014. The code was updated to include all the changes and then the entire data set was rerun. The algorithm changes that were(More)
An analysis is presented of parametric instability in a finite-length rotating cylinder subject to periodic axial compression by small sinusoidal oscillations of one of its ends (the 'piston'). The instability is due to resonant interactions between inertial-wave (Kelvin) modes of the cylinder and the oscillatory compression and is resisted by viscosity,(More)
The exposures (inhalation and dermal) and releases (air, water, solids, and process streams) associated with the filtration of industrial wastewater sludge from an electronics manufacturing plant were characterized. Chemical releases and worker exposures for a target chemical (total copper) were measured over four operational cycles. Various aspects of the(More)
New approaches to thermal management of electronic components are of general interest. Our work demonstrates a novel solution for this applications area. Highly effective thermal management solutions can potentially help the semiconductor manufacturers to reduce costs and meet some milestones of the silicon roadmap. For example, enormous amount of Joule(More)
Pb(Zr,Ti)O<sub>3</sub> (PZT) thin films and nanotube were prepared on SiO<sub>2</sub>/Si substrates by liquid source misted chemical deposition (LSMCD) using Samco MD-6060 apparatus. We report the deposition and characterization of transparent ferroelectric thin films and nanotubes. PZT thin films deposited at ambient conditions and annealing at 700degC(More)
