 | Allen, Edgar S. | Sensory information processing (1 January 1976 - 30 June 1976) | The removal of the effects of atmospheric turbulence from optical images is a significant problem of long standing. Recent investigations by Knox and Thompson have led to the development of a restoration procedure which shows considerable promise. This procedure has not been successfully applied to ... | Removal; Atmospheric turbulence; Interference; Restoration procedure | 1977 |

 | Boll, Steven F. | Suppression of acoustic noise in speech using two microphone adaptive noise cancellation | Acoustic noise with energy greater or equal to the speech is suppressed by filtering a separately recorded correlated noise signal and subtracting it from the speech waveform. This approach was investigated to determine the degree of noise suppression possible using an external correlated input. The... | Suppression; acoustic noise; adaptive noise cancellation | 1979 |

 | Gopalakrishnan, Ganesh | HOP: a process model for synchronous hardware semantics, and experiments in process composition | We present a language "Hardware viewed as Objects and Processes" (HOP) for specifying the structure, behavior, and timing of hardware systems. HOP embodies a simple process model for lock-step synchronous processes. An absproc specification written in HOP describes the externally observable behavior... | HOP; Synchronous hardware semantics | 1988 |

 | Gopalakrishnan, Ganesh | A compositional model for synchronous VLSI systems | Currently available hardware specification languages have two serious deficiencies: (i) inadequate protocol definition capabilities; (ii) lack of a compositional model. We now explain these in more detail. | Very large scale integration; VLSI systems | 1987 |

 | Lindstrom, Gary E. | Referencing and retention in block-structured coroutines | The combination of coroutines with recursive procedures is characteristic of many modern higher-level languages offering advanced control structures (e.g. SIMULA-67, SL5, Interlisp, etc.).
