101 Myers, Chris J.Automatic abstraction for synthesis and verification of deterministic timed systemsThis paper presents a new approach for synthesis and verification of asynchronous circuits by using abstraction. It attacks the state explosion problem by avoiding the generation of a flat state space for the whole design. Instead, it breaks the design into sub-blocks and conducts synthesis and veri...2000
102 Stevens, KennethAutomatic addition of reset in asynchronous sequential control circuitsAsynchronous finite state machines (AFSMs) usually require initialization to place them in a desired starting state. This normally occurs by toggling a reset signal upon power-up. This paper presents an algorithm to automatically generate power-up reset circuitry thus adding reset to an AFSM after t...2014-01-01

105 Myers, Chris J.Automatic derivation of timing constraints by failure analyisAbstract. This work proposes a technique to automatically obtain timing constraints for a given timed circuit to operate correctly. A designated set of delay parameters of a circuit are first set to sufficiently large bounds, and verification runs followed by failure analysis are repeated. Each ver...2002
106 Tasdizen, TolgaAutomatic markup of neural cell membranes using boosted decision stumpsTo better understand the central nervous system, neurobiologists need to reconstruct the underlying neural circuitry from electron microscopy images. One of the necessary tasks is to segment the individual neurons. For this purpose, we propose a supervised learning approach to detect the cell membra...2009

111 Stringfellow, Gerald B.Bandgap control of GaInP using Sb as a surfactantThe use of surfactants to control specific aspects of the vapor-phase epitaxial growth process is beginning to be studied for both the elemental and III/V semiconductors. To date, most reported surfactant effects for semiconductors relate to the morphology of the growing films. However, semicondu...Band-gap energy; Growth process; Epitaxial growth1999-09-27
112 Stevens, KennethBandwidth optimization in asynchronous NoCs by customizing link wire lengthThe bandwidth requirement for each link on a network-on-chip (NoC) may differ based on topology and traffic properties of the IP cores. Available bandwidth on an asynchronous NoC link will also vary depending on the wire length between sender and receiver. We explore the benefit to NoC performance ...2010
