Simulation of a Digital Aircraft Flight Control System

Article Abstract:

It is necessary to simulate digital processes when analyzing the performance of a digital flight control system. Conventional simulation techniques are an expedient way to accomplish this. Digital elements are processed only at their update times and interact with continuous factors through output and sampling processes. For initial studies, only basic parameters need be described; later, additional detail can be added into the simulation. The example of a fighter aircraft control system is used. It is recommended that control systems engineers and software specialists work closely together, and that simulation studies be conducted at preliminary stages so errors can be avoided. Numerous graphs illustrating run results, the effects of filters, and diagrams of filter implementation, the flight control system, and the simulation timing are included.

Three-Dimensional Simulation of Tumor Growth

Article Abstract:

Previous studies of spatial cell growth utilized two-dimensional models. The present study, based on control theory, uses a three- dimensional model. The model includes the life cycles of both normal and tumor cells, cell-cell interactions, and algorithms to describe the effects of anti-tumor treatments on the cells. Certain oversimplifications were made for the sake of expediency. Runs simulating three-dimensional tumor growth and chemotherapeutic treatment were conducted. Various drawings of cells, diagrams of the models, flowcharts for the simulation run and plot routine, and graphs comparing tumor treatment are presented.

A Wish List for Simulation-Language Specifications

Article Abstract:

Guidelines are presented for simulation language specifications. One of the guidelines states that a beginner should be able to use the language without ever learning the advanced features of the language. A new direct-executing language, named DESIRE, is discussed and compared to some of the established languages.
