A method and system for scheduling jobs in a cluster of compute servers using dynamic job profiling improves the overall performance of the computing cluster. Specifically, the method and system monitors the performance of individual compute servers in a cluster, and assigns jobs to particular compute servers based on the most current performance information of the compute servers. As the job profiles of the compute servers change with every job processed, the decision as to which compute server is most appropriate for a particular job will dynamically change. Various scheduling algorithms can be used in connection with the method and system to assign jobs to specific compute servers based on the available information in the job profiles.

A system and method for allocating trades of financial instruments among multiple accounts comprising aggregating orders, wherein each order is associated with an account, and wherein each order has an original order size; allocating an executed order based on the aggregated order in a phase I allocation, wherein the phase I allocation is allocated on a pro-rata basis based on the original order size for each account, except for those accounts that would receive an amount less than a minimum allocation; allocating a remainder from the phase I allocation in a phase II allocation, wherein the phase II allocation is allocated among selected accounts in an amount greater than or equal to the minimum allocation or an amount that fills the original order size; repeating the phase II allocation until a remainder from the phase II allocation is less than the minimum allocation; and allocating a reminder from the phase II allocation in a phase III allocation according to predetermined criteria.

A method for shedding signal load in a network having a plurality of devices is disclosed herein. The method comprises computer-implemented steps of (a) issuing a load-shedding policy, where the policy includes (i) fraction f of the signal to be discarded; (ii) device D where fraction f of the signal is to be discarded; and (iii) pattern P of discarding fraction f of the signal; (b) transmitting the issued load-shedding policy to device D; and (c) discarding portions of the signal at device D according to pattern P until fraction f of the signal is discarded.

A method of load-shedding in a system having a plurality of signal sources is disclosed. The method comprises the steps of: (a) for each signal source Sselected from a set of sources {S, S, . . . }, each source having state pselected from a set of states {p, p, . . . , p; p, p, . . . , p; . . . }, wherein i is an integer greater than one, N is an integer not less than two and k is an integer from 1 to N: (i) obtaining fractions f, wherein each 0&#x2266;f&#x3c;1 is a fraction of a signal from source Sto be discarded if source Sis in state p; and (ii) determining respective state pof signal source Sbased on the signal from source S; and (b) for each source signal Sin determined state p, discarding fraction fof a signal from source S.

An apparatus and a method for detecting cardiac atrial fibrillation events in an EKG signal. The method comprises the steps of detecting a portion of an EKG signal comprising cardiac beats; measuring the duration of a gap in the detected portion of the EKG signal; and computing two or more inter-beat intervals. The computed interval is outputted if the gap in the portion of the EKG signal is not more than a fraction alpha of the computed interval. The method further includes the steps of computing the variance of the inter-beat intervals and classifying the portions of the EKG signal as indicative of an atrial fibrillation event. During classification, the inter-beat interval variance of the portion of the EKG signal that exceeds a pre-determined value V is indicative of an atrial fibrillation event. The method further includes discarding portions of the EKG signal classified as indicative of atrial fibrillation if said portions have a duration less than a pre-determined threshold S and annotating the EKG signal. The non-discarded portions of the EKG signals having inter-beat variances that exceed V are annotated as atrial fibrillation events.

A computer method and system synchronizes one streaming data signal with another data signal. A subject data signal and working data signal are received. The working data signal has predefined coordinates in a coordinate system (e.g., time origin and unit sampling rate in a time coordinate system for audio). The subject data signal and working data signal are transformed into respective common representations. An alignment process aligns the respective transformed representations by matching the transformed representation of the working data signal to that of the subject signal. A re-synchronizer element transposes the predefined coordinates of the working data signal onto the subject signal in the aligned state of the respective transformed representations. As such, the subject data signal is synchronized to the coordinate system of the working data signal.

Computer method and apparatus of analyzing ECG signals of a subject include receiving a subject electrocardiogram signal and comparing it against signal patterns of known cardiac syndromes. A library of example predefined signals is employed. Distance measures indicating similarity of the subject signal to the example predefined signals are produced and form a sequence of vectors. The sequence of vectors are input into a classifier which determines existence of signal patterns indicative of any cardiac syndromes in the subject.

Cardiac diagnostic system and method

Computer method and apparatus for reading and analyzing ECG signals includes applying a plurality of heart condition detectors to a subject ECG signal. Each detector produces a respective indication of likelihood of certain heart conditions existing in the subject. A lattice having annotations of the different detector heart conditions is formed from the detector indications. The lattice enables medical personnel to navigate through and hence more easily read the ECG signal data. The lattice effectively provides an indexed or annotated version of the subject ECG signal.
