Abstract: Described is a system for detection of network activities using transitive tensor analysis. The system divides a tensor into multiple subtensors, where the tensor represents communications on a communications network of streaming network data. Each subtensor is decomposed, separately and independently, into subtensor mode factors. Using transitive mode factor matching, orderings of the subtensor mode factors are determined. A set of subtensor factor coefficients is determined for the subtensor mode factors, and the subtensor factor coefficients are used to determine the relative weighting of the subtensor mode factors, and activity patterns represented by the subtensor mode factors are detected. Based on the detection, an alert of an anomaly is generated, indicating a in the communications network and a time of occurrence.

Abstract: This specification describes a leaf cell resonator sensor based on a geometry of Rhodonea conformal contours joined circumferentially in an eight-fold symmetry by central spoke electrode members. The resonator sensor may provide simultaneous and congruent measurement of fluid density and sound speed based on interaction of the leaf cell dynamics with self-formed Helmholtz cavity dilatational response of the fluid, and the associated changes in electrical admittance spectra in the sensor resulting from changes in fluid acoustic properties. A leaf cell resonator sensor may be capable of retrieving a density and sound speed measurement from fluid independent of the method of deployment, resulting from the principle of the self-formed Helmholtz resonant cavity feature that develops a standing acoustic wave pattern in the fluid without extraneous reflecting structure/hardware.

Abstract: The overall thermal performance of a building UATotal can be empirically estimated through a short-duration controlled test. Preferably, the controlled test is performed at night during the winter. A heating source is turned off after the indoor temperature has stabilized. After an extended period, such as 12 hours, the heating source is briefly turned back on, such as for an hour, then turned off. The indoor temperature is allowed to stabilize. The energy consumed within the building during the test period is assumed to equal internal heat gains. Overall thermal performance is estimated by balancing the heat gained with the heat lost during the test period.
