A Study of Computers and Computer Programming

Computers have become a great aid to scientists and businessmen. Their speed and accuracy had enabled much progress in many fields. Although computers are capable of many tasks, they are dependent upon the programmer and can only do what they are told to do. Computers are based on logical organization and act according to organized data. There are many forms of input used by computers today. Some of the most common forms of input are by typewriter, punched cards, magnetic tape, punched paper taps, and console switches. The typewriter is usually used in accordance with other types of input media. It may be used to correct data which is being read into a computer or to insert needed variables in a standard program. Punched cards are the most common form of input data and will be discussed in detail later in this paper

SIDAC-I a simulated digital-analog computer

SIDAC-I is a digital analog simulator which permits analog as well as hybrid simulations to be programmed on a digital computer. FORTRAN, a scientific computer language, may be included as an integral part of the SIDAC-I simulation language. The simulator consists of a controller program and a set of predefined functional subroutines representing the standard analog computer elements and logical components. Being aware of having the simulator written for a relatively small computer, all the predefined functional subroutines were designed to be independent of the main program and other functional subprograms so that only the functions which are required to solve a certain problem have to be loaded into the computer. This technique of simulation provides not only time saving opportunity, but more space in the core memory for larger simulation problems as well. To implement accurate integration with a high degree of stability SIDAC-I uses the second-order Runge-Kutta integration method. It includes a capability and high degree of flexibility for modifying the parameters and initial conditions. In addition to this, SIDAC-I is capable of accepting some additional computation time to carry on the computation from a point starting with the previous termination time. Although SIDAC-I does not provide the outstanding man-machine rapport all the desirable features that it has will take some of the burden from the man-machine interface

Synthesis of multiple shaped beam antenna patterns

Results are presented of research into the problem of finding an excitation of a given antenna such that the desired radiation pattern is approximated to within acceptable limits. This is to be done in such a fashion that boundary conditions involving hardware limitations may be inserted into the problem. The intended application is synthesis of multiple shaped beam antennas. Since this is perhaps the most difficult synthesis problem an antenna engineer is likely to encounter, the approach taken was to include as a by-product capability for synthesizing simpler patterns. The synthesis technique has been almost totally computerized. The class of antennas which may be synthesized with the computer program are those which may be represented as planar (continuous or discrete) current distributions. The technique is not limited in this sense and could indeed by extended to include, for example, the synthesis of conformal arrays or current distributions on the surface of reflectors. The antenna types which the program is set up to synthesize are: line source, rectangular aperture, circular aperture, linear array, rectangular array, and arbitrary planar array
