Memory Utilization For A Dynamically Microprogrammed Computer, Paul D. Stigall
Memory Utilization For A Dynamically Microprogrammed Computer, Paul D. Stigall
Electrical and Computer Engineering Faculty Research & Creative Works
A Particular, Dynamically Microprogrammed Computer (Proposed by Tucker and Flynn in Commun. of ACM, April 1971) is Considered with Respect to Main Memory and Micro-Memory Utilization. a Dependency is Shown between Memory Utilization and Utilization of the Arithmetic and Logic Unit.
Generalized Feedback Shift Register Pseudorandom Number Algorithm, Theodore Gyle Lewis, W. H. Payne
Generalized Feedback Shift Register Pseudorandom Number Algorithm, Theodore Gyle Lewis, W. H. Payne
Electrical and Computer Engineering Faculty Research & Creative Works
The generalized feedback shift register pseudorandom number algorithm has several advantages over all other pseudorandom number generators. These advantages are: (1) it produces multidimensional pseudorandom numbers; (2) it has an arbitrarily long period independent of the word size of the computer on which it is implemented; (3) it is faster than other pseudorandom number generators; (4) the "same" floating-point pseudorandom number sequence is obtained on any machine, that is, the high order mantissa bits of each pseudorandom number agree on all machines— examples are given for IBM 360, Sperry-Rand-Univac 1108, Control Data 6000, and Hewlett-Packard 2100 series computers; (5) it …
On The Method Of Stationary Phase, Byungkyu Park
On The Method Of Stationary Phase, Byungkyu Park
Electrical and Computer Engineering Faculty Research & Creative Works
The method of stationary phase (MSP), which is an asymptotic method of integration, nevertheless yields general (nonasymptotic) results when applied to certain integrals involving the spherical function. In such cases one may drop the requirement of far-field or high frequency from the results. Copyright © 1973 by The Institute of Electrical and Electronics Engineers. Inc.
Performance Degradation Due To Specular Multipath Intersymbol Interference, G. H. Smith, David R. Cunningham, Rodger E. Ziemer
Performance Degradation Due To Specular Multipath Intersymbol Interference, G. H. Smith, David R. Cunningham, Rodger E. Ziemer
Electrical and Computer Engineering Faculty Research & Creative Works
Plots of performance degradation are used to compare the effects of fading and intersymbol interference in a two-component specular multipath digital communications channel. Similar plots are then used to compare two practical receivers designed to combat the interference. Degradation plots are shown to allow easy identification of each receiver's range of usefulness, as well as identification of variance bounds demanded of channel parameter estimates which the receivers require.

An Accurate Digital Instrument To Measure Reactor Period, Ernest W. Scott, Paul D. Stigall
An Accurate Digital Instrument To Measure Reactor Period, Ernest W. Scott, Paul D. Stigall
Electrical and Computer Engineering Faculty Research & Creative Works
At Facilities Having a Research-Training Reactor, such as the University of Missouri-Rolla Reactor (UMRR), One Finds It Necessary to Perform a Large Number of Rod Calibrations during the Course of the Year. in Practice Rod Worths Are Determined by Measuring the Reactor Period Created by an Incremental Withdrawal of the Rod under Calibration. Period is Then Related to Reactivity Thru the Use of a Publication Such as the AEC Publication, ID016485. This Frequent Measurement of Period Makes It Desirable to Have a Simple, Automatic and Accurate Method to Make Such Measurements. at UMRR We Have Designed, Constructed and Installed Such …
An Improved Single Flight Technique For Radar Stereo, Gordon E. Carlson
An Improved Single Flight Technique For Radar Stereo, Gordon E. Carlson
Electrical and Computer Engineering Faculty Research & Creative Works
An improved technique for obtaining stereo radar image pairs is described. The technique uses a unique combination of two different radar beam pattern characteristics. The resulting stereo radar images are illuminated from very nearly the same aircraft position which results in radar shadow and back-scatter characteristics which are very similar and in improved image registration possibilities. The reduction in illumination angle and aircraft position differences is shown to be nearly an order of magnitude or more when compared with a previously proposed single flight technique which used two vertical fan beam patterns at different azimuth angles. As a related sidelight …
Tilt-Table Alignment For Inertial-Platform Maintenance Without A Surveyed Site, Gordon E. Carlson, Max E. Bott
Tilt-Table Alignment For Inertial-Platform Maintenance Without A Surveyed Site, Gordon E. Carlson, Max E. Bott
Electrical and Computer Engineering Faculty Research & Creative Works
A method for aligning the rotary tilt table for an inertial-platform maintenance facility without surveying the site is analyzed and evaluated. The method utilizes multiple measurements of the tilt-table azimuth alignment error with different inertial platforms to determine a best estimate of the alignment error. Error analysis indicates that useful facility performance can be obtained with only a small number of measurements. The tilt-table alignment accuracy can be improved as more measurements of the alignment error are made during normal facility operation. © 1973, IEEE. All rights reserved.
