The radiation dose accumulated by blood diverted through a shunt by Boeing Company( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

Modern techniques have made it possible to divert a portion of the circulating blood through a shunt outside the body--for example in heart-lung machines, artificial kidneys, and coiled tubes where the blood may be exposed to radiation without danger to body tissues. There is some probability theory connected with such procedures, for the cells of the blood are thoroughly mixed in the body, and hence the number of times a blood cell passes through the shunt is a random variable. Several papers have been written to describe such systems by differential equations; this paper discusses the problem directly in terms of probability theory, finding the exact distribution of the number of times a blood cell has passed through the shunt and, in addition, a normal approximation which makes calculation of accumulated doses a matter of simple arithmetic.

One-line random number generators and their use in combinations by George Marsaglia( Book )

2 editions published in 1968 in English and held by 2 WorldCat member libraries worldwide

This is a discussion of some one-line random number generators, requiring a single FORTRAN instruction, together with a description of some short FORTRAN programs which mix several such generators. Evidence suggesting that the simple congruential generators are unsatisfactory continues to grow; one of the most promising alternatives is to mix several simple generators. These composite generators do better in various tests for randomness than do the simple congruential generators used at many computer centers
Moment crossings as related to density crossings( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

In this paper it is shown how the number of moment crossings of two symmetrical densities is related to the number of crossings of the densities. This generalizes a result of Fisher's recently proved by Finucan (1964) (A note on Kurtosis). (Author)
Optimal representation of a function as a linear combination of functions( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

This paper discusses the approximation of a given density function g(x) with a linear combination of densities f sub one (x), f sub two (x) ..., f sub n (x) in such a way that the approximation has maximum area but always lies below the given function

Some problems involving circular and spherical targets( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

This article is concerned with some problems which occur in certain tactical considerations: how should one place k circles (spheres) in the plane (3-space) so that their union has the greatest standard normal probability measure, that is, so as to maximize the probability that a random normal point will fall in one or more of the circles (spheres). For k> 3 the problem seems hopeless, (except for certain special situations); the case for k = 3 is still unresolved and is being worked on by a number of investigators, and the case for k = 2 is solved completely in this paper. The results for k = 2 have some practical value when applied to actual problems arising in tactical considerations, and some theoretical value, as a method of attacking the problem for k> 3. (Author)
Random variables with independent binary digits( Book )

1 edition published in 1970 in English and held by 1 WorldCat member library worldwide

Let X = .b1b2b3 ... be a random variable with independent binary digits bn taking values 0 or 1 with probabilities pn and qn. When does X have a density function. A continuous density function. A singular distribution. This note proves that the distribution X is singular is and only if the tail of the series Summation (log(pn/qn)) squared diverges, and that X has a density that is positive on some interval if and only if log(pn/qn) is a geometric sequence with ratio 1/2 for n greater than some k, and in that case the fractional part of (2 to the power k)X has an exponential density (increasing or decreasing with the uniform density a special case). It gives a sufficient condition for X to have a density, (Summation log (2 max (pn, qn))converges), but unless the tail of the sequence log(pn/qn) is geometric, ratio 1/2, the density is a weird one that vanishes at least once in every interval.

A method for producing random variables in a computer( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

This paper describes a general procedure for producing random variables in a computer. The idea is to represent the required X in the form: X = C (M + U sub 1 + U sub 2 + U sub 3), some 97 - 99% of the time, where c is constant, M is a discrete random variable taking perhaps 8 values, and the U's are uniform random variables; the other 1 - 3% of the time. X is generated from a residual density by the rejection technique. These two methods for producing X are combined in the proper proportions in order that the resulting distribution for X be correct. The method is general in that it applies to a wide variety of density functions. Programs based on this procedure are very fast and require little computer storage space - typically, 18 constants and 20 instructions. (Author)
One-sided approximations by linear combinations of functions( Book )

1 edition published in 1969 in English and held by 1 WorldCat member library worldwide

The paper discusses how to approximate a function g(x) from one side by a linear combination of functions f sub 1 (x) ..., f sub n (x) so as to minimize the area between the two. It discusses the problem as one of finding the point where a moving hyperplane last touches a convex set and an approximate procedure based on linear programming methods. It gives details of an algorithm for solving the problem, examples, and applications to Monte Carlo Theory--generating random variables in a computer. (Author)
Still another method for producing normal variables in a computer( Book )

1 edition published in 1965 in English and held by 1 WorldCat member library worldwide

A method for producing normal random variables in terms of uniform random variables U sub 1, U sub 2, U sub 3 ... If Y = U sub 1 + U sub 2 + U sub 3, then choosing one of the four random variables 2Y - 3, (4Y - 6)/3, (Y - 7)/2 or (Y + 4)/2 in the proportions .8365, .11506, .00372 and .00372 will produce the required normal variate 98.6 per cent of the time. The other 1.4 per cent is devoted to the tail or a rejection technique in order that the composite be exact. The method leads to very fast computer programs which are easy to code and occupy little space in the computer. (Author)

Regularities in congruential random number generators( Book )

1 edition published in 1969 in English and held by 1 WorldCat member library worldwide

The paper suggests that points in n-space produced by congruential random number generators are too regular for general Monte Carlo use. Regularity was established previously for multiplicative congruential generators by showing that all the points fall in sets of relatively few parallel hyperplanes. The existence of many containing sets of parallel hyperplanes was easily established, but proof that the number of hyperplanes was small required a result of Minkowski from the geometry of numbers--a symmetric, convex set of volume 2 to the nth power must contain at least two points with integral coordinates. The present paper takes a different approach to establishing the course lattice structure of congruential generators. It gives a simple, selfcontained proof that points in n-space produced by the general congruential generator r sub (i+1) is identically eaual to a(r sub i) + b mod m must fall on a lattice with unit-cell volume at least m to the power (n-1). There is no restriction on a or b; this means that all congruential random number generators must be considered unsatisfactory in terms of lattices containing the points they produce, for a good generator of random integers should have an n-lattice with unit-cell volume 1.

RATIOS OF NORMAL VARIABLES AND RATIOS OF SUMS OF UNIFORM VARIABLES( )

1 edition published in 1964 in English and held by 0 WorldCat member libraries worldwide

The principal part of this paper is devoted to the study of the distribution and density functions of the ratio of two normal random variables. It gives several representations of the distribution function in terms of the bivariate normal distribution and Nicholson's V function, both of which have been extensively studied, and for which tables and computational procedures are readily available. One of these representations leads to an easy derivation of the density function in terms of the Cauchy density and the normal density and integral. A number of graphs of the possible shapes of the density are given, together with an indication of when the density is unimodal or bimodal. The last part of the paper discusses the distribution of the ratio u sub 1 + ... + u sub n) (V sub 1 + ... + V sub m) where the u's and v's are independent, uniform variables. The exact distribution for all n and m is given, and some approximations discussed

THE CUMULATIVE EFFECT OF RANDOM LOSSES IN A TRANSMISSION LINE( )

1 edition published in 1963 in English and held by 0 WorldCat member libraries worldwide

A study was made of the probability distribution of losses from reflections at discontinuities in a transmission line, on the assumption that the reflection coefficients at the discontinuities have random phase, and, in addition, random magnitudes associated with manufacturing uncertainties (tolerances)
