Terasaki","doi":"10.1109/TEC.1962.5219317","DOIUrl":"https://doi.org/10.1109/TEC.1962.5219317","url":null,"abstract":"A method is described for the analog computation of the solution of linear two-point boundary value problems, i.e., the problem of a linear ordinary differential equation with linear two-point boundary conditions. The nonhomogeneous problem, in particular, is considered; the differential equal for y on the real interval 0?x?1 is taken to be nonhomogeneous. The method for its solution is based upon the integral formula for the solution, namely, y(x) = ?01G(x, t)f(t)dt, where G(x,t) is the Green's function satisfying two-point boundary conditions while f is a known integrable function. The paper describes a method for finding a specific set of initial value problems whose solutions, taken in linear combination, form the Green's function whose second argument (t) is fixed. This technique reduces the two-point boundary value problem to a set of initial value types and makes the continuous computation of the Green's function as a function of x for fixed t amenable to analog means. The application of the described technique to the adjoint boundary value problem yields a means for continuous computation of G as a function of the second argument (t) for fixed values of the first argument (x). This is the required form for the analog evaluation of the integral formula. The theoretical aspects of the method found are stated, after which an example of a simple non-self-adjoint problem from the study of structures is solved on an electronic analog computer.","PeriodicalId":177496,"journal":{"name":"IRE Trans.

McLeod","doi":"10.1109/TEC.1962.5219308","DOIUrl":"https://doi.org/10.1109/TEC.1962.5219308","url":null,"abstract":"The past and present of computer simulation are examined, and on that basis some predictions for the future are made. Deploring the analog vs digital concept fostered by some, the author stresses the complementary aspects of the two methods. Then, drawing heavily on the experience of others as well as his own, the more important improvements in simulation techniques and equipment of the past ten years are discussed. The two approaches to analog-digital simulation?the hybrid-computer in which both techniques are combined in one machine, and the combined-simulation in which relatively pure analog and digital computers are connected to operate together?are both viewed as attempts to capitalize on the unique advantages inherent in each method, and as presenting common problems. The requirement for better education, not only of the potential user?the scientist, the engineer, and the researcher in other fields such as biology and medicine?but of the undergraduate and the public, is found to be the greatest need. Improved equipment having greater reliability?for somewhat less money?is also needed. But it is predicted that that will come. It is the need for education which demands the attention of all who are interested in the furture of computer simulation.","PeriodicalId":177496,"journal":{"name":"IRE Trans. Electron.
