A system and method for rapidly responding to triggering events or activities in a network system. The system includes a policy enforcement function, a policy manager function, and one or more network devices of the network system. The policy enforcement function includes one or more installed policy sets and/or policy enforcement rule sets suitably responsive to triggering events or activities. Upon detection of a trigger, the policy manager function analyzes the trigger and selects one or more appropriate policy sets and/or policy enforcement rule sets deemed to be responsive to the trigger. Each set has a unique rapid response identifier. The policy manager function signals for implementation of the one or more policy and/or rule sets, based on one or more rapid response identifiers, which are enforced through the policy enforcement function. The policy enforcement function may be a part of one or more of the one or more network infrastructure devices for implementing the policy change. The system and method enable rapid response to a detected trigger (which might be a manual input) by pre-installing responsive policy and/or rule sets first and then generating and transmitting the unique rapid response identifier(s) corresponding to one or more selected policy and/or rule sets for implementation. That is, the network device is already configured with a response through the pre-installed policy and/or rule sets. Responses may be implemented and/or removed gradually, and different network devices may be instructed to implement different policies in response to the same trigger and the same policy may be implemented with different policy enforcement rules on different devices, ports, or interfaces.

A data warehouse design that combines data from multiple source ledgers or modules is constructed and from that an associated, single physical Star or Snow-Flake schema and OLAP hyper-cube analytic structure is generated to enable cross-functional analysis of any those multiple source ledgers or modules. The step of constructing the data warehouse or the step of generating the associated OLAP cube is achieved without significant human intervention using software. The present invention is based on the insight that the technical bias against generating individual data marts and OLAP cubes from multiple source ledgers is not well founded. Previously, the norm has been to generate a single physical OLAP cube for each individual ledger—hence one for the General Ledger, a further one for sales order processing etc. This prior art approach makes cross functional analysis multiple source ledgers and sub-ledgers difficult since it requires the creation of a further level of physical or virtual cubes across multiple physical cubes and complex querying. This is no longer necessary with the present invention.

What is disclosed is a non-contact system and method for determining cardiac function parameters from a vascular pattern identified from RGB and IR video signals captured simultaneously of a region of exposed skin of a subject of interest. In one embodiment, a video of a region of exposed skin is captured using a video camera that captures color values for pixels over visible channels and an IR camera that measures pixel intensity values in wavelength ranges of interest. Pixel intensity values are processed to generate a vascular binary mask that indicates pixel locations corresponding to the vascular pathways. The IR images are registered with corresponding data from the camera's visible channels such that pixels that correspond to the vascular pattern can be isolated in each frame of the video of visible color data. Once processed, pixels associated with the isolated vascular patterns are analyzed to determine desired cardiac function parameters.

A dependability measurement system for use in a communications network includes several functional components which work together to measure, analyze and report the dependability parameters and metrics. A performance measurement function measures performance parameters between a first location and a second location in the communications network. A service-affecting event computation function analyzes performance parameters measured by the performance measurement function. An equipment event measurement function monitors network elements of the communications network for occurrence of network element events. A population calculator determines components within the communications network which are related to the dependability metrics to be reported upon and calculates in-service time information for the components. Finally, a dependability metric calculator calculates, analyzes and reports user requested dependability parameters and metrics using information output from the service-affecting event computation function, equipment event measurement function and population calculator.

A system and method is presented for determining at what price and when to release so-called ‘flex’ price tickets during an on-sale using hazard functional analyses of sales velocity and sales/inquiry ratios. Exponential, power, and Weibull-gamma models are also used to predict demand, depending on what part of the on-sale is involved. Determining demand of seats from secondary markets is also described with methods to use the demand for either repricing the seats in the primary market or presenting ‘best value’ seats to a prospective purchaser. Demand can be interpolated or extrapolated to individual seats or rows.

A multimodal intravascular analysis uses a structural intravascular analysis modality to compensate for a chemical analysis modality. Examples of structural analysis are IVUS, OCT, including optical coherence domain Reflectometry (OCDR) and optical frequency domain imaging (OFDI), and/or sonar range finding. Examples of chemical or functional analysis are optical, NIR, Raman, fluorescence and spectroscopy, thermography and reflectometry. In one example, the structural analysis is used to characterize the environment structurally, such as catheter head-vessel wall distance. This information is then used to select from two or more algorithms which are depth specific (e.g. shallow vs. deep), to achieve improved accuracy in the chemical or functional analysis.

Systems and methods are described for acquiring, processing, and presenting boundaries of a cavity-tissue interface within a region-of-interest in an ultrasound image based upon the strength of signals of ultrasound echoes returning from structures within the region-of-interest. The segmentation of boundaries of cavity shapes occupying the region-of-interest utilizes cost function analysis of pixel sets occupying the cavity-tissue interface. The segmented shapes are further image processed to determine areas and volumes of the organ or structure containing the cavity within the region-of-interest.

This invention focuses on the marriage of solid-state electronics and neuronal function to create a new high-throughput electrophysiological assay to determine a compound's acute and chronic effect on cellular function. Electronics, surface chemistry, biotechnology, and fundamental neuroscience are integrated to provide an assay where the reporter element is an array of electrically active cells. This innovative technology can be applied to neurotoxicity, and to screening compounds from combinatorial chemistry, gene function analysis, and basic neuroscience applications. The system of the invention analyzes how the action potential is interrupted by drugs or toxins. Differences in the action potentials are due to individual toxins acting on different biochemical pathways, which in turn affects different ion channels, thereby changing the peak shape of the action potential differently for each toxin. Algorithms to analyze the action potential peak shape differences are used to indicate the pathway(s) affected by the presence of a new drug or compound; from that, aspects of its function in that cell are deduced. This observation can be exploited to determine the functional category of biochemical action of an unknown compound. An important aspect of the invention is surface chemistry that permits establishment of a high impedance seal between cell and a metal microelectrode. This seal recreates the interface that enables functional patch-clamp electrophysiology with glass micropipettes, and allows extracellular electrophysiology on a microelectrode array. Thus, the invention teaches the feasibility of using living cells as diagnostics for high throughput real-time assays of cell function.

In one aspect, a database analytical tool or function analyzes join queries to detect queries which could be reduced if a referential integrity relationship were known. In another aspect, a probable latent referential integrity relationship is detected using one or more heuristics. Preferably, a join query is analyzed to detect a joined table which has no other conditions placed on it, and no referential integrity relationship already defined. For any such query, the analysis attempts to verify a probable latent referential integrity relationship using at least one heuristic, such as comparing cardinality of the potential primary key with the size of the table and/or with the cardinality of the foreign key. It is further possible to execute the join for some sample of records, and determine whether any records were found which did not conform to referential integrity constraints.

A method for functional analysis of neurophysiological data by decomposing neurophysiological data and EEG signal to form a plurality of signal features. The signal features may then optionally be analyzed to determined one or more patterns.

Known methods of heart function analysis, while useful, suffer from a number of limitations. These include the fact that these methods are inherently static, in that they consider an individual ECG that can only provide a picture of heart function at a particular moment in time. Furthermore, the assessment depends upon the expertise of specialists performing a visual analysis of ECG traces, which may be subjective, and of limited sensitivity. The present invention provides a method of processing ECG signals. The method comprises the steps of extracting data from at least one ECG signal determining a time derivative of said data and generating a normalised index value representative of the energy in said time derivative. Accordingly, the method provides an index that may be used as an objective indication of heart function, and recorded for an individual patient over a period of time as a dynamic record of any change in heart function of the patient that may be indicative of abnormal function or heart disease.
