OdeView is the graphical front end for Ode, an object-oriented database system and environment. Ode's data model supports data encapsulation, type inheritance, and complex objects. OdeView provides facilities for examining the database schema (i.e., the object type or class hierarchy), examining class definitions, browsing objects, following chains of(More)
A formation-flying sensor that can determine spacecraft separation with a maximum uncertainty of 2 cm, measure the bearing angles of the remote spacecraft with a maximum uncertainty of a minute of arc, and operate with a wide field of view autonomously in deep space has been designed and prototyped. It is the autonomous formation-flying (AFF) sensor that(More)
Comparisons of experimental and calculated interproton nuclear Overhauser effect (NOE) buildup curves for duplex d(CGCGAATTCGCG)2 have been made. The calculated NOEs are based on molecular dynamics simulations including counterions and water and on the single-structure canonical A, B, and crystal forms. The calculated NOE effects include consideration of(More)
DEX is a high level tool designed to aid distributed system experimentation. It supports a very general model of distributed system and provides features to simulate different communication networks, work loads, failure patterns, and communication delays. It uses UNIX processes and communication mechanisms for implementing a distributed system testbed. The(More)
OdeView is the graphical front end for Ode, an object-oriented database system and environment. It is intended for users who do not want to write programs in Ode's database programming language O++ to interact with Ode but instead want to use a friendlier interface to Ode. OdeView is based on the graphical direct manipulation paradigm that involves(More)
