Abstract:

A collaborative client-server system having performance reliability improvement (PRIM) includes collaboration techniques for sharing server data among two or more servers, each server coupled to one or more client computers. A communication link between a client computer and a server is handed off to another respective one of the two or more servers under a variety of conditions. Hand off conditions include, congestion of the server processing load, congestion of the communication link between the client computer and the server, and loss of data signal integrity between the client computer and the server.

Abstract:

Techniques for modeling living biological systems include receiving constant values for multiple interaction factors w. A set of initial state values is received for state variables that indicate relevant properties of a living biological system. Also received is a set of trial values for perturbation variables that indicate factors that might affect one or more of the relevant properties of the biological system. A temporal change in a value for a particular state variable is determined based on a non-linear transformation of a sum of the trial value for the perturbation that affects the particular state added to a sum of all non-zero values for a product of wand a state variable over all state variables. In some embodiments, measurement-based values are received for a measurable subset of the state variables. Values for the constant interaction factors ware determined based on the measurement-based values.

Abstract:

A dual-energy X-ray absorptiometry (“DXA”) system includes an x-ray source assembly comprising a source carriage to move the x-ray source assembly along a scan path, the scan path comprising an active scan portion and a reference measurement portion. A detector assembly including a detector carriage to move the detector assembly with the source assembly and to collect scan data at active scan portions. A support structure supporting the source and detector assemblies. A calibration controller coupled a calibration element having a known x-ray attenuation value and configured position the calibration element between the source and detector assemblies during the reference measurement portion and to remove the calibration element from between the source and detector assemblies during the active scan portion. A processing unit operable to compare the reference measurement against an expected reference value to identify a variance and to selectively trigger an action in response to the variance.

Abstract:

A carbonate microfluidic model with controllable nanoscale porosity and methods are described. The method for fabricating a carbonate nanofluidic micromodel with controllable nanoscale porosity for studying fluid behaviors in an underground oil-reservoir environment includes: disposing a plurality of polymer spheres into a transparent flow cell; initiating crystallization of the plurality of polymer spheres to form a template with an opal structure; filling the transparent flow cell with a calcium-based solution and a carbonate-based solution to form nanocrystals in voids of the opal structure; and removing the template formed by crystallization of the plurality of polymer spheres from the transparent flow cell leaving an inverse opal structure with a plurality of nanoscale pores and a carbonate surface. The model includes: a transparent flow cell including a first end defining an inlet and a second end defining an outlet; and an inverse opal structure of carbonate inside the transparent flow cell.
