RECONSTRUCTION OF SIGNALS FROM PHASE: EFFICIENT ALGORITHMS, SEGMENTATION, AND GENERALIZATIONS
It is well known that the phase of the Fourier transform of a signal contains a significant amount of information about the signal. Under certain circumstances the knowledge of phase is sufficient to recover the original ...
THE DESIGN OF DFT ALGORITHMS
A broad class of efficient discrete Fourier transform algorithms is developed by partitioning short DFT algorithms into factors. The factored short DFT's are combined into longer DFT's using multidimensional index maps. ...
LASER PROCESSING OF SEMICONDUCTORS
The great potential for advancing the state of the art in fabrication of semiconductor devices and integrated circuits with the use of laser beam processing techniques is reviewed. The unique characteristics of this novel ...
ANALYSIS AND DESIGN OF PERIODICALLY TIME-VARYING DIGITAL FILTERS
A description of periodically time-varying systems was developed which completely characterizes the relationship between the spectra of the input and output signals of these systems. The description is the bi-frequency ...
RESTORATION AND FUNCTIONAL ANALYSIS OF NUCLEAR MEDICINE IMAGES
The nuclear medicine physician uses visual interpretation of a movie-like display of the beating human heart to detect wall motion abnormalities which might be related to impaired cardiac function. The present work is ...
REAL-TIME RECONSTRUCTION AND NOISE PERFORMANCE FOR A TIME-OF-FLIGHT POSITRON EMISSION TOMOGRAPHY SYSTEM
Several researchers have proven the benefits of using time-of-flight data in Positron Emission Tomography (TOFPET). Related areas which are investigated here are: (1) The mathematical description of the measurement and ...
