  • An important aspect of detection of anomalies in signals is the identification of changes in signal behavior caused by noise, jumps, changes in band-width, sudden pulses and signal bias. A methodology is developed to identify, isolate and characterize these anomalies using a modification of the cumulative sum (CUSUM) approach. The new algorithm performs anomaly detection at three levels and is implemented on a general purpose computer. 7 refs., 4 figs.
  • A combined Shewhart CUSUM statistical process control procedure is being implemented at Savannah River Site for monitoring groundwater effluent concentrations. The procedure is being developed for the Environmental Monitoring Section and will be available to yield information on remediation performance in real-time for improved decision making. The method is outlined and an application given to monitoring trichloroethylene concentrations at a Savannah River Site point of compliance well. The combined charting methods incorporate the strengths of both charting methods. This intra-well comparison method will provide a visual tool for detecting both abrupt changes and increasing or decreasing trends in constituent concentrations.
  • The details of the Josephson effect in thin metal bridges are difficult to derive quantitatively, and many papers have been written on the subject attempting to describe quantitatively such qualitative features as irreversible phase slip, instantaneous 2$pi$ phase slip, variation of order parameter in time and space, Bernoulli effect, and others. It does not seem to be generally recognized that all of these qualitative features are universal attributes of the Josephson effect and occur also in tunnel junctions. In addition, when a steady voltage is impressed across a junction, a term in the electric field is set up (in additionmore » to the Bernoulli field) which has a rather complex temporal and spatial variation.

  • The eigenvalue problem associated with the equations of motion of a compressible, fluid-conveying, cantilevered, Bernoulli-Euler beam or tube is solved using Muller's method. Compressibility affects the dynamics of the system through tube aspect ratio and fluid sonic velocity. Parametric studies indicate that aspect ratio has a more pronounced influence on the critical velocity than sonic velocity. 15 references.
