  • Patent number: 10830713
    Abstract: A method for computing physical properties of materials, such as two-phase and three-phase relative permeabilities through a porous material, is described. The method employs single or multi-scale digital images of a representative sample which capture one or multiple fractionations of a micro-structure size cascade at the respective, required imaging resolutions. At a high resolution, the method computes basic physical properties, such as absolute permeabilities with a numerical method such as computational fluid dynamics solving the Navier-Stokes equation, and capillary pressure with simulations solving Young-Laplace equation. Saturation states of multiple fluids are combined to derive capillary pressure relationships at low resolutions when necessary.

  • Patent number: 10797939
    Abstract: The invention relates to a node for communication between a first network and an second network and coupled to a controller in the second network via a first communication route. The node and controller form a virtualised home gateway platform. The node is arranged to access a second communication route and also to couple to the controller via the second communication route upon connection failure of the first communication route. This reconnects the node to the controller thereby maintaining a route for transmission of data streams and downloads into the home environment but also re-establishes control signalling within the virtualised home gateway platform and therefore also within the home network. A system for performing gateway functions between a first network and an second network, and a method of maintaining connection between a node and a controller, are also described.

  • Publication number: 20190108322
    Abstract: A method for computing the release rate of a controlled release drug and medical device using a combination of imaging data and computational physics is described. The method employs a three-dimensional digital representation of a drug sample, derived from two-dimensional or three-dimensional imaging, which captures the drug active pharmaceutical ingredient (API), excipients, and porosity with distinctive contrasts. Direct numerical simulations are conducted on the three-dimensional digital representation to derive effective transport properties of the API going through a porous matrix or membrane. Drug release rate can be predicted more efficiently than laboratory-based methods. When there is strong heterogeneity presented in the drug, a further method is described that engages imaging and release simulations at multiple scales. Computerized systems and programs for performing the methods are also described.
