Low cost computer graphics in engineering education
(Elsevier, 1981)
The Apple II is a personal computer which provides 6 color, raster graphics via a 280 h x 192 v frame buffer. A user-programmable MOS Technology 6502 CPU addresses 48 K bytes of RAM, 12 K of ROM. and 4 K of memory-mapped ...
On the statistics of random pulse processes
(Elsevier, 1971-05)
Statistics are obtained for pulse trains in which the pulse shapes as well as the time base are random. The general expression derived for the mean and spectral density of the pulse train require neither independence of ...
The spectral analysis of impulse processes
(Elsevier, 1968-03)
An expression for the spectral density of the impulse process s(t) = {if236-1} is derived under the assumption that [alpha]n}} is a stationary process, and that n}} is a stationary point process independent of [alpha]n}}. ...
High Order Fluctuation Schemes on Triangular Meshes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-12)
We develop a new class of schemes for the numerical solution of first-order steady conservation laws. The schemes are of the residual distribution, or fluctuation-splitting type. These schemes have mostly been developed ...
Sampling theorems and bases in a Hilbert space
(Elsevier, 1961-09)
A unified approach to sampling theorems for (wide sense) stationary random processes rests upon Hilbert space concepts. New results in sampling theory are obtained along the following lines: recovery of the process [chi](t) ...
Functional differential equations and age dependent population growth
(Elsevier, 1972-08)
Growth equations are established for a population of individuals that have fixed age dependent reproduction and mortality rates. Equations are obtained both for the population density and for the numerical size of the ...
Random sampling of random processes: Stationary point processes
(Elsevier, 1966-08)
This is the first of a series of papers treating randomly sampled random processes. Spectral analysis of the resulting samples pre-supposes knowledge of the statistics of tn, the random point process whose variates represent ...
Recovery of randomly sampled signals by simple interpolators
(Elsevier, 1974-12)
The mean square error performance of simple polynomial interpolators is analyzed for wide-sense stationary signals subjected to randomly timed sampling represented by stationary point processes. This performance is expressed ...
