Abstract: A method and apparatus for computer-assisted project analysis. Planned values for successive times for each of a plurality of parameters are stored in a database. Another database receives measured values of the parameters at the successive times. A statistical analysis including comparison, correlation and differentiation functions generate a set of output functions that then are displayed to assist in the analysis of the project.

Abstract: A computerized system and method are provided that may be used to project a plurality of risk levels that may develop during the course of a large development project. A plurality of inputs are stored and converted for use to a metric that is used by an expert knowledge rule based system to determine a plurality of risk levels that develops relating to successful completion of a large development program with respect to elements such as cost, time of delivery, and quality. A plurality of outputs are provided in a form that can be used by a program manager to reduce the level of risk that may arise. In a preferred embodiment, the plurality of outputs are provided in a quantified manner that may relate to a probability of failure of one or more aspects of the development program. The rules are based on the knowledge and experience of experts and are predetermined so that risk levels are objectively quantified prior to beginning the project rather than subjectively determined during the course of the project.

Abstract: The present invention relates to an intelligent personal underwater monitng system which recognizes when a swimmer is in trouble and transmits a warning signal. The system comprises a device worn by the swimmer which senses water pressure and transmits a first signal when a predetermined depth is passed by the swimmer. The system further comprises a device for receiving the signals generated by the device worn by the swimmer and a neural network processor for processing the signals and generating an output signal representative of whether the swimmer is in trouble and an alarm signal generation device.

Abstract: In accordance with the present invention, a method for obtaining frequency nformation about a given data set is realized. The method comprises the steps of providing a processing unit; inputting a raw data set into the processing unit; optionally removing at least one trend from the raw data; ordering the raw data; estimating power spectral density using an eigenanalysis approach and the inputted raw data and the ordered raw data; simultaneously estimating the power spectral density using the raw data and a periodogram; generating a time-series representation of the raw data to which curve fitting is applied; comparing the results from the power spectral density estimating steps and the time-series representation generating step to determine if any frequencies suggested by the eigenanalysis approach estimating step are valid; and generating an output signal representative of each valid frequency.
