Title: Method of upscaling permeability for unstructured grids
Inventor: KHAN SAMEER A
IPC: G01N15/08
Filed: 2000-06-21
Abstract: A method is provided for scaling up permeabilities associated with a fine- scale grid of cells representative of a porous medium (fig.1) to permeabilities associated with an unstructured coarse-scale grid of cells representative of the porous medium (fig.3). An areally unstructured, Vorono i, computational grid is generated using the coarse-scale grid as the genesis o f the computational grid. The computational grid is then populated with permeabilities associated with the fine-scale grid. Flow equations are developed for the computational grid, the flow equations are solved, and int er- node fluxes and pressure gradients are then computed for the computational grid. These inter-node fluxes and pressure gradients are used to calculate inter-node average fluxes and average pressure gradients associated with the  coarse-scale grid. The inter-node average fluxes and average pressure gradients associated with the coarse grid are then used to calculate upscale d permeabilities associated with the coarse-scale grid.

Title: Method and apparatus for secure digital chaotic communication
Inventor: PARKER ANDREW
IPC: G06F7/58
Filed: 1999-11-09
Abstract: A method and apparatus that uses control of a chaotic system to produce secure digital chaotic communication. Controls are intermittently applied by a transmitter-encoder (12) to a chaotic system to generate the 0 and 1 bits of a digital message. A new control/no control bit stream is thereby created in which a 0 indicates that no control was applied and a 1 indicates that a control was applied. The control/no control bit stream and a prepended synchronization bit stream are transmitted, using conventional transmission technologies (14), from the transmitter-encoder to an identical receiver-decoder (16). A chaotic system in the receiver-decoder is driven into synchrony and is subject to intermittent controls based on the control/no control bit stream, thereby causing it to generate the digital message.

Title: Electrical heater housing support wall
Inventor: ST LOUIS ROBERT MAURICE
IPC: D06F58/26
Filed: 2002-10-24
Abstract: An electrical heater housing support wall for use in a heater assembly of a clothes dryer is adapted to support electrical resistant insulators carrying heating elements. The heater housing support wall has a series of leaves folded together to provide a continuous substantially annular wall portion for supporting an electrical heating element relative thereto. Each of the leaves has an outer peripheral end portion, an inner periphery end portion narrower in width than said outer peripheral end portion, and opposing tapering side walls tapering from the outer peripheral end portion to the inner peripheral end portion. The leaves are connected together at their outer peripheral end portions and at least partially engage each other along respective juxtapostioned tapering side walls. The assembled heater housing support wall has the advantage that during assembly of the heating elements onto the support wall, the support wall is not yet folded permitting the heating elements to be evenly stretched linearly for mounting onto the insulators.
