A team was created to participate in the Mars Scout Opportunity. Trade studies determined that an aircraft provided the best opportunity to complete the science objectives of the team. A high fidelity six degree of freedom flight simulation was required to provide credible evidence that the aircraft design fulfilled mission objectives and to support the aircraft design process by providing performance evaluations. The team created the simulation using the Langley Standard Real-Time Simulation in C++ (LaSRS++) application framework. A rapid prototyping approach was necessary because the team had only three months to both develop the aircraft simulation model and evaluate aircraft performance as the design and mission parameters matured. The design of LaSRS++ enabled rapid-prototyping in several ways. First, the framework allowed component models to be designed, implemented, unit-tested, and integrated quickly. Next, the framework provides a highly reusable infrastructure that allowed developers to maximize code reuse while concentrating on aircraft and mission specific features. Finally, the framework reduces risk by providing reusable components that allow developers to build a quality product with a compressed testing cycle that relies heavily on unit testing of new components.

Title from cover

User interface management systems (UIMSs) that support rapid prototyping often suffer from the limited range of interfaces that they can produce and the lack of support for the connection between the produced interface and its underlying application. This paper discusses a Mode Development Environment (MoDE) that addresses these problems. MoDE is a general user interface management system that supports rapid creation of a wide variety of user interfaces. It is implemented on top of Smalltalk-80 and an event-driven mechanism. Its dynamically expandable interaction technique library allows the interface developer to easily introduce new objects into the library. MoDE also supports creation and management of the connection between the user interface and the application through direct manipulation. Keywords: User interface software.

1Sin of Monsieur Pettipon, and other humorous tales

By Richard Connell

Collection of short stories originally published in the Saturday Evening Post.

Vivian Connell introduces you to Corinna Lang, goddess of the movies. Corinna, who was bored with mammoth swimming pools, small MG's, fat directors, slim leading men - bored with the whole great golden illusion of Hollywood. Mr. Connell takes you with his enchanting heroine to the wicked, extravagant Riviera where the golden Corinna, undertaker of a top secret mission, lives in the shadow of international intrigue, and matches her quick wit with the most dangerous men in Europe.
