 | Sobh, Tarek M.; Henderson, Thomas C. | A dynamic framwork for intelligent inspection | CAD Computer Aided Design typically involves the design manufacture and inspection of a me chanical part. The problem of reverse engineering is to take an existing mechanical part as the point of departure and to inspect or produce a design and perhaps a manufacturing process for the part. ... | CAD; Manufacture; Inspection; Intelligent inspection | 1992 |

 | Sobh, Tarek M.; Henderson, Thomas C. | A dynamic recursive structure for intelligent exploration | We suggest a new approach for inspection and reverse engineering applications. In particular, we investigate the use of discrete event dynamic systems (DEDS) to guide and control the active exploration and sensing of mechanical parts for industrial inspection and reverse engineering. We introduce dy... | Intelligent exploration; Discrete event dynamic systems; DEDS; Dynamic recursive finite state machines; DRFSM | 1992 |

 | Gopalakrishnan, Ganesh | Asynchronous circuit verification using trace theory and CCS | We investigate asynchronous circuit verification using Dill's trace theory as well as Milner's CCS (as mechanized by the Concurrency Workbench). Trace theory is a formalism specifically designed for asynchronous circuit specification and verification. CCS is a general purpose calculus of communicat... | Trace theory; Verification; CCS | 1992 |

 | Sobh, Tarek M. | Autonomous Observation | We address the problem of observing an agent. We advocate a modeling approach for the visual system and its observer, where a discrete event dynamic system (DEDS) framework is developed and "events" are defined as ranges on parameter subsets. The dynamic recursive context for finite state machines (... | Observation; Manipulation process | 1992 |

 | Akella, Venkatesh | CFSIM: A concurrent compiled-code functional simulator for hopCP | Control intensive ICs pose a significant challenge to the users of formal methods in designing hardware. These ICs have to support a wide variety of requirements including synchronous and asynchronous operations, polling and interrupt-driven modes of operation, multiple concurrent threads of executi... | CFSIM; Hardware design; hopCP | 1992 |

 | Gopalakrishnan, Ganesh | Dynamic reordering of high latency transactions in time-warp simulation using a modified micropipeline | Time warp based simulation of discrete-event systems is an efficient way to overcome the synchronization overhead during distributed simulation. As computations may proceed beyond synchronization barriers in time warp, multiple checkpoints of state need to be maintained to be able to rollback inva... | Asynchronous design; Micropipelines; Dynamic instruction reordering; Time warp simulations | 1992 |

 | Gopalakrishnan, Ganesh | HOP: A formal model for synchronous circuits using communicating fundamental mode symbolic automata | We study synchronous digital circuits in an abstract setting. A circuit is viewed as a collection of modules connected through their boundary ports, where each port assumes a fixed direction (input or output) over one cycle of operation, and can change directions across cycles. No distinction is ma... | HOP | 1992 |
