The network monitoring system collects transmission and/or receive power level information from a plurality of customer premise devices connected to the same distribution node for each of a plurality of network distribution nodes. For an individual network distribution node, the network monitoring system calculates a set of fluctuation parameters including a group power level deviation metric, e.g., a modified standard deviation ratio. The network monitoring system evaluates the generated fluctuation parameters and responds, e.g., outputting a fluctuations report, modifying a data collection profile being used by a set of customer premise devices corresponding to a distribution node, commanding diagnostics to be performed on a portion of the network and/or directing a service technician. The network monitoring system compares generated fluctuation parameters corresponding to different distribution nodes, and uses the results of the comparison to assign priority with regard to the assignment of limited available troubleshooting and repair resources.

Response data such as survey data and/or neuro-response data including Event Related Potential (ERP), Electroencephalography (EEG), Galvanic Skin Response (GSR), Electrocardiograms (EKG), Electrooculography (EOG), eye tracking, and facial emotion encoding data may be used to determine resonance and priming levels.

A method and system for achieving stability while reallocating resources in a logically partitioned environment. The present invention comprises Performance Enhancement Program (PEP), Classification Program (CP), System Analysis Program (SAP), and System Evaluation Program (SEP). PEP allows a user to enter several performance parameters. CP classifies each of the virtual systems in the managed system based on their workload. SAP analyses the managed system to determine the configuration of the managed system. Managed systems configurations are classified according to the reciprocity of resource allocation and the overall symmetry of the managed systems. SEP evaluates the configuration of the managed system and recommends alterations for improved performance of the managed system. The managed system will be optimized when the functional differentiator (FD) of the virtual systems is small enough to allow reallocation of resources without an unacceptable sacrifice in managed system stability.

A description of a user is estimated based on the context of a user's past and present locations. A disclosed data-processing system continually receives data points for each user that represent spatial and/or temporal events. These events represent, for example, presence of a person at a specific geographic location such as a geographic area or point of interest (POI). The data-processing system evaluates the received data points in relation to one or more of the geographic locations, yielding results that are also based on the demographic characteristics of each visited location and the commercial characteristics of each visited location. The data-processing system evaluates the data points also to determine patterns exhibited in each user's activity or inactivity, and patterns exhibited in the distance traveled and the type of travel. The data-processing system bases the user descriptions on the results of these evaluations.

A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.

A computer-implemented method and system evaluates and displays a return on investment for using weather-related risk-management services. The system includes user interfaces, databases containing information about the accuracy of different forms of weather-related risk-management services and the types and frequency of weather events in different geographical areas, and return on investment functions. The system accepts information about a user's costs of responding to weather warnings and events, retrieves information from its databases and applies the appropriate function to determine a return on investment. The result is then displayed to the user. The method determines the costs of weather-related risks faced by a user under two different risk-management services and compares them, determining a return on investment for the use of one service over the other.

A multi-media method and system performs psychological assessment of an individual for suitability for particular jobs, whereby the individual is shown and provided with discrete visual and auditory stimuli on a multi-media computer screen, so that the individual's responses can be monitored in conjunction with physiological responses received by biofeedback sensors. The computer tallies the test subject's recorded responses. Virtual work environments are optionally displayed, to enable the tested individual to simulate a real work environment. Unlike other job evaluation systems, the system evaluates a job candidate's ability to maintain task focus under pressure. It directly measures performance under pressure, rather than only inferring potential performance based upon selective input from a job candidate.

An improved system and procedure for controlling the audio broadcast to users participating in a group conversation. In one embodiment, a communications server employs arbitration logic to decide which of the user has priority to speak, and accordingly mixes only the audio data steams for those users for broadcast to all users. The server can send notification to the user interfaces to inform the users of their current priority status and to allow the users to request that their priority be increased, decreased, eliminated, or passed on for the benefit of another user. A user may also attempt at his user interface to affect the priority of identified other users by informing the arbitration logic of a rating for that user. Additionally, a systems administrator may also arbitrate user priorities, either at his discretion or in conjunction with suggestions provided by the arbitration logic. Finally, and regardless of system-assessed priorities, a user may at his user interface tailor the group conversation broadcast to him by either blocking reception of audio from certain users or by reducing their volume, or may tailor his outgoing audio transmission so they are blocked from being received by selected group conversation participants.

A wellbore evaluation system evaluates mechanical wear and corrosion to components of a well system including a production tubing string positionable in a well and a sucker rod string movable within the production tubing string. A deviation sensor determines a deviation profile of the well, a rod sensor senses and measures wear and corrosion to the sucker rod string as it is removed from the well to determine a rod profile, and a tubing sensor senses and measures wear and corrosion to the production tubing string as it is removed from the well to determine a tubing profile. A data acquisition computer is in communication with the sensors for computing and comparing two or more of the respective deviation profile, rod profile, and tubing profile as a function of depth in the well. A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.
