Disclosed is a method and system that adapts coefficients of taps of a Finite Impulse Response (FIR) filter to increase elimination of Inter-Symbol Interference (ISI) introduced into a digital communications signal due to distortion characteristics caused by a real-world communications channel. In the communications system there is a Finite Impulse Response (FIR) filter. The FIR filter has at least one pre and / or post cursor tap that removes pre and / or post cursor ISI from the signal, respectively. The pre / post cursor taps each have pre / post cursor coefficients, respectively, that adjusts the effect of the pre / post cursor portion of the FIR filter. The FIR filtered signal is transmitted over the channel which distorts the signal due to the changing and / or static distortion characteristics of the channel. The channel distorted signal is received at a receiver that may pass the channel distorted signal through a quantifier / decision system (e.g., a slicer) as the quantifier input signal to quantify the quantifier input signal to one of multiple digital values. The channel distorted signal may be further adjusted by summing the channel distorted signal with the output of a Decision Feedback Equalizer (DFE) filter to create a DFE corrected signal which then becomes the quantifier input signal. An error signal is determined by finding the difference between the scaled quantifier decision and the quantifier input signal. The pre / post cursor coefficient values that adjust the effects of the pre / post cursor taps of the FIR filter are updated as a function of the error signal and at least two quantifier decision values, and update coefficient values, may be sent over a communications back-channel to the FIR filter.

Disclosed herein is a method and system for hardware-accelerating various data processing operations in a rule-based decision-making system such as a business rules engine, an event stream processor, and a complex event stream processor. Preferably, incoming data streams are checked against a plurality of rule conditions. Among the data processing operations that are hardware-accelerated include rule condition check operations, filtering operations, and path merging operations. The rule condition check operations generate rule condition check results for the processed data streams, wherein the rule condition check results are indicative of any rule conditions which have been satisfied by the data streams. The generation of such results with a low degree of latency provides enterprises with the ability to perform timely decision-making based on the data present in received data streams.

The present invention relates to application processing and decisioning systems and processes. One embodiment of the invention includes a method for automating decisioning for a credit request associated with an applicant. The method includes providing a user computer interface adapted to receive information associated with an applicant, and further adapted to display and receive information associated with at least one decision rule. The method also includes receiving information associated with an applicant through the user computer interface; receiving information associated with the applicant from at least one data source; and receiving a selection of information associated with a plurality of decision rules through the user computer interface. Furthermore, the method includes receiving a selection of rule flow information associated with the plurality of decision rules through the user computer interface; generating a plurality of decision rules based at least in part on the information associated with the applicant, based at least in part on the information associated with the applicant from at least one data source, and based at least in part on the selection of information associated with a plurality of decision rules, wherein an outcome associated with the at least one decision rule can be obtained; and based in part on at least the rule flow information, displaying at least a portion of the plurality of decision rules through the user computer interface.

A mechanism for running interactive applications with a minimal set of privileges is disclosed. The privileges form a subset of the privileges afforded to the user requesting the application and are allocated consistent with the principle of least privilege. The application runs with the minimal amount of permissions necessary to accomplish its assigned tasks. A new user account is created and provisioned or identified for each application to which a user requests access. The accounts have a subset or superset of the access rights and operating system privileges that the user who is logged on to the system and requesting access to the application ordinarily enjoys. The subset / superset of the user's privileges is determined by a policy-based decision system. The policy-based decision system makes its determination based on an analysis of the application requirements, an analysis of the data security and privacy concerns associated with the execution of the application, the identity of the user and user's role and any other policy considerations previously specified by an administrator. Once the determination as to the appropriate set of privileges to be afforded in the execution environment has been made, the execution environment is created and provisioned or a pre-existing execution environment possessing the requisite privileges is identified and the remote user is logged into the server-side account. The application-specific accounts may be audited by audit trail tools that provide evidence of policy enforcement.
