Scale and Translation Invariant Methods for Enhanced Time-Frequency Pattern Recognition
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-10)
Time-frequency (t-f) analysis has clearly reached a certain maturity. One can now often provide striking visual representations of the joint time-frequency energy representation of signals. However, it has been difficult ...
Dependability and Performance Measures for the Database Practitioner
(1998-05-01)
We estimate the availability, reliability, and mean transaction time (response time) for repairable
database configurations, centralized or distributed, in which each service component is continuously available for ...
Reconstruction of 3D Whole-Body PET Data Using Blurred Anatomical Labels
(IEEE, 1998-11-08)
The diagnostic utility of whole-body PET is often limited by the high level of statistical noise in the images. An improvement in image quality can be obtained by incorporating correlated anatomical information during the ...
Electron-interface phonon interaction in multiple quantum well structures
(IOP Publishing Ltd, 1998-08-01)
Intersubband relaxation rates due to electron interactions with the interface phonons are evaluated for multiple quantum well structures designed for step quantum well lasers operating at mid-infrared to submillimetre ...
Statistical Image Reconstruction Methods for Randoms-Precorrected PET Scans
(Elsevier, 1998-12)
Positron emission tomography (PET) measurements are usually precorrected for accidental coincidence events by real-time subtraction of the delayed-window coincidences. Randoms subtraction compensates on average for accidental ...
Performance Measurement of the PeopleSoft Multi-Tier Remote Computing Application
(Center for Information Technology Integration, 1998-06)
The Center for Information Technology Integration has undertaken a study of the potential impact of PeopleSoft software on U-M production computing environments, focusing on the measurement and modeling of the Peoplesoft ...
Lightweight Secure Group Communication
(Center for Information Technology Integration, 1998-04-14)
An advantage of today's high speed networks is the ability to support group communication. Applications that support group communication allow the free exchange of ideas and data in real time, regardless of the physical ...
SiGe/Si Monolithically Integrated Amplifier Circuits
(University of Michigan. Radiation Laboratory, 1998-02)
Discrete Gel'fand-Levitan and Marchenko matrix equations and layer stripping algorithms for the discrete two-dimensional Schrödinger equation inverse scattering problem with a nonlocal potential
(IOP Publishing Ltd, 1998-06-01)
We develop discrete counterparts to the Gel'fand-Levitan and Marchenko integral equations for the two-dimensional (2D) discrete inverse scattering problem in polar coordinates with a nonlocal potential. We also develop ...
Electromagnetic Scattering from Short Branching Vegetation
(University of Michigan. Radiation Laboratory, 1998-12)
