Group communication, providing virtual synchrony semantics, is a powerful paradigm for building distributed applications. For applications that require a large number of groups, signi cant performance gains can be attained if these groups share the resources required to provide virtual synchrony. A service that maps multiple user groups onto a small number of instances of a virtually synchronou...

We built a limited but successful user interface management system named HYPE which supports rapid interactive creation and organization of user interfaces for a large class of applications. HYPE is targeted at applications for which the user interface is only loosely coupled to the application. Examples of this class of application are ‘command line-driven’ programs. Many applications in this ...

The objective of the research is to optimize the empennage of a light weight aircraft such as Zenith aircraft. The case is specified by a unique set of geometry, materials, and strength-to-weight factors. The anticipated loads associated with the empennage structure are based on previous light aircraft design loads. These loads are applied on the model to analyze the structural behavior conside...
