A software architecture for a commander's display system

One of the main tasks of a command and control system is to present commanders with a basis for understanding the tactical situation. A system that transforms a large volume of data into a comprehensive picture that can then be used for situations assessment can aid the commander's decision making process. A system capable of preforming this task has, until recently, required the dedication of vast amounts of computer resources. This report suggests a structure for a commander's display system that relies on recent advances in computional power in the form of a small high-powered, dedicated graphics workstation. A prototype system is included as part of the research effort.Prepared for: Naval Ocean Systems Center, San Diego, CA.http://archive.org/details/softwarearchitec00zydaApproved for public release; distribution is unlimited

Workstation graphics capabilities for the 1990's and beyond

We present in this paper a look at the future graphics capabilities of the workstation. We begin by examining the cycles of special hardware development that have occurred for graphics systems in general. We show how the current evolution of the graphics workstation is a direct response to applications user desires for higher performance, graphics systems. The software and hardware levels that perform the input and output graphics operations for the workstation are described with an eye towards categorizing future graphics capabilities. The implementation of those levels in the Silicon Graphics, Inc. IRIS is cited as an example of the leading edge for graphics workstation is presented as a continuation of the historical response to applications user desires for ever higher performance, interactive systems.

Computer graphics interactive workshop for two-dimensional fractals

We present in this study an interactive computer graphics workshop for two-dimensional fractals. The workshop enables the user to learn about fractals through experimentation with the generation of Koch-like fractal curves. A variety of Koch-like fractal curves, Julia sets and the Mandelbrot set are presented as examples. Algorithms are presented for creating the Mandelbrot set and for creating Kock-like fractal curves. Keywords and Phrases: fractals, Kock-like Fractal curves, Julia sets, interactive computer graphicsU.S. Army Combat Development Experimentation Center (USACDEC) under MIPR ATEC 46-86 and in part by funds provided through the Commodore Grace Murray Hopper Research Chair in Computer Science at the Naval Postgraduate School.http://archive.org/details/computergraphicsin00masoN0003986WRDQ200N

A simulation study of an autonomous steering system for on-road operation of automotive vehicles

The study of human driving of automotive vehicles is an important aid to the development of viable autonomous vehicle navigation techniques. Observation of human behavior during driving suggests that this activity involves two distinct levels, the conscious and the unconscious. Conscious actions relate to the logical behavior of a driver such as stopping the vehicle when a traffic light is red, slowing down the vehicle when it turns a bend, etc. Such behavior can be described using natural human language. The unconscious actions of a driver are much less obvious. There are many such activities occurring while we are driving a vehicle to a particular destination. One of the important unconscious efforts involves the selection of successive points on the road to steer the vehicle towards in order to achieve the desired road-following behavior. This research work attempts to mimic this unconscious behavior through the use of a computer simulation model. Keywords: Robotics; Artificial intelligence; Mobile; Mathematical models.
