Abstract: The invention concerns a method and a system for predicting the apparent flow conductivity of a heterogeneous medium. According to the invention, the following steps are implemented:—choosing a flow conductivity element type with a given set of characteristic parameters;—determining equations for said flow in said element type;—determining a network statistics for said given set of characteristic parameters; and—performing a stochastic homogenisation of said equations, for said network statistics. The invention applies more particularly to the predicting of the apparent viscosity of non-Newtonian fluids in a heterogeneous porous medium.

Abstract: A method for creating a digital caricature combining aspects of a tourist destination with a likeness of a face. Digital backgrounds are drawn embodying themes associated with a tourist destination and various digital bodies are drawn. The backgrounds and/or bodies may be animated. A caricature booth or the like is set up at the tourist destination and the backgrounds and bodies are displayed for selection by a customer. A face is drawn onto the selected body and the face and body are superimposed on the selected background to create a digital caricature. The digital caricature is copied to a CD or other digital media for the customer. An E-card may also be created to allow the customer to share the animated caricature over the Internet. A link to a web site for the vacation destination may be provided on the animation window and on the E-card for advertising.

Abstract: A system and a concomitant method for providing programming content in response to an audio signal. The programming content and the audio signal are transmitted in a network having a forward channel and a back channel. In one embodiment, the system comprises a local processing unit and a remote server computer. A first user provides a first audio signal containing a request for programming content from a service provider. The local processing unit receives the first audio signal and transmits the received first audio signal to a service provider via the back channel. The remote server computer receives the first audio signal from the back channel, recognizes the first user and the request for programming content, retrieves the requested programming content from a program database and transmits the programming content to the local processing unit via the forward channel.

Abstract: A query message-based call routing mechanism for a limited access cooperative telecommunication network initially determines whether the called party is commonly located at the same node as the calling party. If not, the calling party node broadcasts a query message to all other nodes in the network to locate the called party. Only the node having local knowledge of the called extension will reply to the query message. Once the node sourcing the query message has received this reply message, it will place a call to the node servicing the called extension.

A spacer for a sealed insulating unit has side walls in which are defined elongate recesses, the dimensions of the recesses being selected such that sufficient primary sealant can be accommodated to provide in the sealed insulating unit opposed primary seals each at least 0.4 mm thick.

Abstract: It has been unexpectedly found that greatly improved properties for tire rubbers, such as lower hysteresis, can be attained by coupling the rubber with both a tin halide, such as tin tetrachloride, and a silicon halide, such as silicon tetrachloride. Even better characteristics for use in tire tread compounds can be realized by asymmetrically coupling the rubbery polymer. This invention more specifically discloses a coupled rubbery polymer which is particularly valuable for use in manufacturing tire tread compounds, said coupled rubbery polymer being comprised of (1) tin atoms having at least three polydiene arms covalently bonded thereto and (2) silicon atoms having at least three polydiene arms covalently bonded thereto.

Abstract: A polymerisable cement composition, particularly for dental and biomedical uses, comprises a mixture of polymerisable monomer materials including between 5 and 95% by weight tetrahydrofurfuryl methacrylate (THFMA), and at least 5% by weight secondary monomer, preferably a dimethacrylate; and active filler material, preferably powdered fluoroaluminosillicate glass, capable of undergoing an acid-base reaction in the presence of water with acid or acid derivative groups in the composition. The composition is conveniently in the form of a resin-modified glass-ionomer cement or a compomer composition. The use of THFMA as a monomer material has a number of advantages. THFMA has low shrinkage on polymerisation, good biological acceptability and advantageous water uptake properties in comparison to other monomer systems. The invention also covers a method of preparing a polymerisable cement, and a method of dental treatment.
