TASC is developing the Integrated Model Development Environment (IMDE) as a software environment for airbase logistics modeling. The authors describe the methodology for developing the user interface (UI). A UI prototyping process is planned to elicit task-oriented requirements from users of current airbase simulations. An interactive prototyping methodology was developed as an alternative to formal task analysis due to the absence of an existing user base from which to gather task information. An initial graphical UI (GUI) is designed based on analyses of projected user's and expert's conceptual (mental) models of airbase logistics and simulations. A cognitive network method is used for mental model extraction, which is based on knowledge acquisition methods from artificial intelligence. This network of expert/user concepts affords the design of GUl prototypes that map to the expert/user's conceptual model of the domain.<>

The authors discuss the design and development of the Visual Interactive Simulation Interface Tool (VISIT). VISIT was designed to provide the graphical representation and user interface for a simulation that is running on another processor utilizing internet communications. Since the simulation processor may be any system capable of implementing the proper network protocol, specialized processors with no graphics display devices can benefit from this architecture. The system provides support for various input devices to control the simulation display and environment. Simulation objects are displayed using either a 3D wireframe representation or a Gouraud shaded representation. Viewer interaction with the simulation is provided by a collection of commands that allow the viewer to initialize, start, stop, abort, and restart the simulation. The viewer also has the ability to establish checkpoints. Upon reaching a checkpoint the viewer can step through the output display and/or manipulate the objects within the simulation.<>

Modular avionics are in the process of supplanting traditional LRU (line replaceable unit) based avionics on new military aircraft and will see initial applications on commercial transport aircraft in the mid to late 1990s. The author discusses the major considerations which must be addressed for modular avionics on commercial transport aircraft as well as the needs of commercial versus military modular avionics systems. Douglas Aircraft Company's work in commercial modular avionics is summarized and some thoughts on architectures and implementation are provided.<>

A methodology for designing a closed-loop motion simulation is discussed. This procedure is applicable to a centrifuge simulator as well as other types of devices which can produce both motion and visual fields. The key issues of coordinating the motion field with the visual simulation are discussed. Both systems are driven by the stick commands of the pilot, thus making it closed loop. The motion fields simulated are based on supermaneuvarable flight trajectories where research is needed to investigate how these supermaneuvers influence the ability of a pilot to perform a mission. It has been shown in performance studies that an agile aircraft has a definite combat edge over a nonagile aircraft. Using agility, a tactical maneuver can be performed expending less overall aircraft energy.<>

An IGEFET has been coupled with a chemically active, electron-beam evaporated copper phthalocyanine (CuPc) thin film to realize a gas-sensitive microsensor. The sensor can selectively detect parts-per-billion concentration levels of nitrogen dioxide (NO/sub 2/) and diisopropyl methylphosphonate (DIMP). The sensor is excited with a voltage pulse, and the time- and frequency-domain responses are measured. The envelopes associated with the normalized difference Fourier transform magnitude frequency spectra reveal features which unambiguously distinguish the NO/sub 2/ and DIMP challenge gas responses. The area beneath each response envelope can correspondingly be interpreted as the sensor's sensitivity for a specific challenge gas concentration.<>

Transputer arrays and the Trollius operating system are explored as means for implementing adaptive search experiments. Synthesis of image operators with evolutionary learning is a search process involving a large population of candidate solutions which undergo systematic variation and evaluation. A genetic algorithm produces the candidates with the highest performance measures (survival functions). These solutions have the highest probability of reproducing and increasing their attributes in the population. It is noted that such search processes have a natural parallelism which facilitates the use of transputer arrays. It is concluded that the introduction of transputers provides a relatively inexpensive means of enhancing the computational power necessary for attacking practical problems in computer vision and evolutionary search. A secondary advantage is that they provide a flexible testbed to stimulate further investigation and evaluation of parallel algorithms for distributed computing systems.<>

Innovative organizations have recently been developing executive information systems (EISs) which automatically extract predetermined relevant data out of the business' 'stovepiped' departmental computers and combine them into an integrated view of the organization. Creative and graphical values of this integrated information are then presented to managers in formats they help design. These formats reduce the time executives require to grasp the current status of performance relative to organizational goals. EIS application generation tool software is designed to allow quick reaction (minutes or hours) by EIS staff to requests from executives for new data views.<>

Basic controllers which apply to process control are reviewed. Common types of controllers discussed are two-position, proportional, integral, derivative, proportional plus integral, proportional plus derivative and proportional plus integral plus derivative. The author presents a simple method for adjusting the controller when it is installed on a system, making use of the online manual-tuning procedure. Having shown that the controller settings can be obtained in the field, it will be possible for the engineer/operator to tune the controller for certain applications and thus determine the controller parameters even before the process reaction curve is built.<>

A systematic approach to testing a software system is described. The description can be used as a guideline to establishing a test operation on a software development eject. The authors address primarily the integration test level of testing, although all levels of testing are discussed. Included are test objectives, test documentation requirements, and the use of automated test tools in the testing process. The concept and approach described are based on DOD software development life cycle standards and were used on the Air Force Logistics Command's Reliability and Maintainability Information System (REMIS) project.<>
