摘要:

A stochastic model for the spread of a communicable disease is formulated. The problem was firat studied by Landau and Rapoport (1953) using as a basis a deterministic integral equation of the Volterra type. We present here a detailed study of the random integral equation which arises in the probabilistic model

摘要:

In this paper, an algorithm is presented which greatly facilitates the synthesis of optimal manufacturing systems by means of digital computation. The algorithm is based upon the use of the set-theoretic methods previously developed by Sewell and Porter (1971 a, b).

摘要:

The quasilinearization technique is applied to a pursuit-evasion game involving an interceptor and a supersonic bomber. Aerodynamic forces and variable density effects are included. A technique for treating the singularity in the linearized differential equations at the final time is described. Means of expanding the region of convergence are described and utilized to obtain good convergence properties in the example treated. The technique is also applied to determine worst case performance of a specified suboptimal intercept strategy. Quantitative measures are thus obtained for the guaranteed performance and the best possible guaranteed performance.

摘要:

The paper considers the determination of the value of a boolean function by examining its variable. The function's value is deterministically determined by the variables which arc binary and random. A sequential testing procedure of the variables is presented. It is shown that this procedure minimizes the expected number of necessary tests for some classes of functions and probably do so for others. The presence of such problem is described in file searching, reliability systems, switching circuits and graph connectivity.

摘要:

This paper deals with the synthesis of 2-level networks of threshold logic elements for realizing non-linearly separable switching functions. Gate minimality has been ensured for the types of gates used. The method is straightforward and can be programmed in a computer.

摘要:

In this paper we propose a hypothetical scheme for recognizing the alphanumerics. The scheme is based on the known physiological structure of the visual cortex and the concept of a short Lino extractor nouron (SLEN). We assumo four basic typca of such units for extracting vertical, horizontal, right and left inclined straight line segments. The patterns reconstructed from the scheme show perfect agreement with the test patterns. The model indicates that the recognition of letters T and H requires extraction of the largest number of features.
