Abstract: A method of measuring and analyzing the ultra high frequency EKG is performed by measuring the EKG within the frequency range above 250 Hz with a dynamic range of at least 100 dB. In the UHF EKG signal positions of Rm of R wave in QRS complex of EKG are detected on the time axis and the EKG signal is converted to amplitude or power envelopes, the amplitude or power envelopes frequency range is anywhere within the limits from 0.2 Hz to at least 500 Hz. From these envelopes the amplitude and time numerical parameters that describe the myocardium depolarization inhomogeneity and electric myocardium dyssynchrony are determined, and these parameters are used for selecting the patients for multi-chamber stimulators implementation and optimization of their setting.

Abstract: A technique includes tracking changes to a code base using a source code management application; and maintaining a correlation between defects in the code base and changes addressing the defects. The technique includes determining a defect density in a subset of the code base associated with implementation of a requirement for the code base. Determining the defect density includes identifying how many defects are addressed by changes that modify the subset of the code base.

Abstract: Disclosed herein is a system and method that determine whether activity pertaining to a software development project violates at least one development rule whose associated severity level exceeds a predetermined threshold.

Abstract: A system to generate an interactive layered visualization of a software system includes a storage device to storage a model of the system that defines entities and relationships among entities. The system also includes a visualization tool to generate nodes representing the entities and assign nodes to layers in a set of ordered layers in accordance with rules associated with each layer. A layered layout of the software system is thereby generated and an interactive visualization of the layered layout is rendered for display to the user.

Abstract: A technique to determine defect density in a portion or subset of code. Changes to code may be tracked. Defects in the code that are addressed by the changes may also be tracked. A defect density in a portion or subset of the code having a characteristic can be determined by identifying changes modifying the portion or subset of the code and that address a defect.

Abstract: Systems and methods for epicardial pacing are provided. For example, this document provides epicardial pacing using a percutaneously delivered bifurcated pacing lead that has multiple electrodes that are directionally insulated to prevent extracardiac stimulation, including prevention of phrenic stimulation. In addition, the devices, systems, and methods provided can be used for ablation, defibrillation, and/or defibrillation in combination with pacing.

Abstract: A computer implemented method includes extracting requirement data from a software development system, the requirement data defining a software development requirement during a predetermined period of time. The method further includes extracting from the software development system an indication of a state of software development at the beginning of the period of time, and an indication of a state of software development at the end of the period of time. The method further includes calculating a change in the state of software development during the period of time and generating a report that enables comparing the calculated change in the state of software development with the software development requirement. A computer readable medium product and a data processing system are also disclosed.

Abstract: A test planning tool for defining a test plan for testing updates to a software product aggregates information from a variety of diverse sources to generate an application model. The application includes a detailed model of the components of the application and their dependencies, a logical structure of the components, requirements associated with changes to the components, organizational entities responsible for the changes, and various other information, such as test coverage and defect information. The application model is presented to the user in a manner that allows the user to select components of interest, drill down and view change details and requirements, and to use that information to develop a test plan.

Abstract: A vane assembly, particularly suitable for a transverse flow, or vertical axis, turbine or a propulsion device includes a vane with at least one concavo-convex part that is mounted by a pivot so that it is free to rotate about a pivot axis. The pivot connects the vane to a rotor with an axis of rotation. The pivot axis is inclined to the concave face such that, as the rotor turns, the vane is free to rotate about the pivot axis between a first position in which the vane defines a high-drag configuration for retreating with a transverse fluid flow, and a second position in which the vane defines a reduced-drag configuration for advancing against the transverse fluid flow.

Abstract: A method of migrating artifacts between service-oriented architecture repositories is provided herein. The method includes receiving a request to export an artifact from a first repository. The artifact comprises metadata associated with a service-oriented architecture. Additionally, the method includes retrieving data from one or more aggregated relationships of the artifact. The method also includes packaging the retrieved data into a data store comprising the selected data.

Abstract: A system and method for predicting a pole slip in a synchronous generator is provided. The system includes a stator voltage frequency detector to determine the frequency of the stator voltage, a mechanical frequency detector to determine the rotational speed of the rotor and a prediction unit that is operative to disconnect the generator from a power grid if it determines that that a pole slip is likely based on comparison of the frequency of the stator voltage and the rotational speed of the rotor.

Abstract: A method and system of maintaining a computing services repository, including: accessing service data stored in a configuration database to populate a services repository with services and the service data from the configuration database; performing on-going service discovery to synchronize the services depository and the configuration database; and managing service data imported to the services repository from the configuration database.

Abstract: A method and appertaining system for implementing the method are provided for managing a software service component in a service oriented architecture (SOA) model, in which aspects maintained by an SOA repository for the service component or software system using the component are made openly available. A series of lifecycle stages for a service component are defined, as are the criteria for promoting the service components to a more advanced life cycle stage. A user/developer/enterprise architect provides a service component at an earlier lifecycle stage and then submits a promotion request for the service component to approver, who assess compliance with the requirement. If the service component complies with the requirement, it is promoted to the next life cycle stage.
