1 Khan, Faisal HabibA 5 kW Bi-directional multilevel modular DC-DC converter (MMCCC) featuring built in power management for fuel cell and hybrid electric automobilesAbstract- A new capacitor clamped modular dc-dc converter with bi-directional power handling capability will be presented in this paper. This inductor-free design is modular, and it is possible to integrate multiple loads and sources simultaneously in the converter. Moreover, this 5 kW dc-dc convert...2007
2 Mathews, V. JohnA minimax approach for the joint design of acoustic crosstalk cancellation filtersAbstract-This paper presents a method for jointly designing immersive audio rendering filters for a single listener using loudspeakers. The filters for crosstalk cancellation are assumed to have finite impulse responses and are designed using the minimax criterion. In addition to the traditional At...2007
3 Tasdizen, Tolga; Whitaker, Ross T.Automatic assembly of TEM mosaics and mosaic stacks using phase correlationThis paper discusses automatic Transmission Electron Microscopy (TEM) image registration, TEM slice assembly via tile mosaicking, and TEM volume assembly via slice to slice registration. Several algorithms are presented, including an algorithm for mosaic layout of an unordered set of tiles, an algor...2007
4 Stringfellow, Gerald B.; Sadwick, Laurence P.Chemical beam epitaxial growth of InP and GaP by using tertiarybutylbis (dimethylamino) phosphineWe report the growth of indium phosphide (InP) by using a chemical beam epitaxy (CBE) technique with the group V source tertiarybutylbis (dimethylamino) phosphine (TBBDMAP). The photoluminescence spectra at 15 K showed that the intensity of a peak attributed to impurity recombination and the FWHM i...Chemical beam epitaxy; CBE; InP; GaP; Tertiarybutylbis (Dimethylamino) Phosphine; Gallium phosphide; TBBDMAP2007
5 Myers, Chris J.Design of a genetic muller C-elementSynthetic biology uses engineering principles to design circuits out of genetic materials that are inserted into bacteria to perform various tasks. While synthetic combinational Boolean logic gates have been constructed, there are many open issues in the design of sequential logic gates. One such g...2007
6 Stevens, KennethDynamic gates with hysteresis and configurable noise toleranceDynamic logic can provide significant performance and power benefit compared to implementations using static gates. Unfortunately dynamic gates have traditionally suffered from low noise margins, which limits their reliability. A new logic family, called complementary dynamic logic (CDL), is prese...2007
7 Stringfellow, Gerald B.Effects of low surfactant Sb coverage on Zn and C incorporation in GaPThe use of surfactants during the vapor phase growth of III-V materials to control fundamental characteristics of epitaxial layers is becoming increasingly important. We have investigated the remarkable effects of Sb, from triethylantimony (TESb) Pyrolysis, on the Zn doping during the organometallic...Surfactants; Organometallic vapor phase epitaxy; Gallium phosphide2007
8 Myers, Chris J.Efficient verification of hazard-freedom in gate-level timed asynchronous circuitsAbstract-This paper presents an efficient method for verifying hazard-freedom in gate-level timed asynchronous circuits. Timed circuits are a class of asynchronous circuits that are optimized using explicit timing information. In asynchronous circuits, correct operation requires that there are no ha...2007
9 Stringfellow, Gerald B.Fundamentals of vapor phase epitaxial growth processesThe first success with the growth of semiconductor materials by vapor phase epitaxy (VPE) dates back to the 1950's. Today, it is the largest volume technique for the production of both Si and HI/V electronic and photonic devices. Of course, commercial processes for the growth of Si layers, dielectri...Vapor phase epitaxy; Surfactants2007
10 Mathews, V. JohnLow-delay nonuniform pseudo-QMF banks with application to speech enhancementAbstract-This paper presents a method for designing low-delay nonuniform pseudo quadrature mirror filter (QMF) banks. This method is motivated by the work of Li, Nguyen, and Tantaratana, in which the nonuniform filter bank is realized by combining an appropriate number of adjacent sub-bands of a uni...2007
11 Harrison, Reid R.;Normann, Richard A.Low-power integrated circuit for a wireless 100-electrode neural recording systemIn the past decade, neuroscientists and clinicians have begun to use implantable MEMS multielectrode arrays (e.g., [1]) to observe the simultaneous activity of many neurons in the brain. By observing the action potentials, or "spikes," of many neurons in a localized region of the brain it is possibl...Neural recording system; Utah Microelectrode Array; Integrated neural interface2007
12 Khan, Faisal HabibMultiple load-source integration in a multilevel modular capacitor clamped DC-DC converter featuring fault tolerant capabilityAbstract-A multilevel modular capacitor clamped dc-dc converter (MMCCC) will be presented in this paper with some of its advantageous features. By virtue of the modular nature of the converter, it is possible to integrate multiple loads and sources to the converter at the same time. The modular con...2007
13 Myers, Chris J.Symbolic model checking of analog/mixed-signal circuits*Abstract- This paper presents a Boolean based symbolic model checking algorithm for the verification of analog/mixedsignal (AMS) circuits. The systems are modeled in VHDL-AMS, a hardware description language for AMS circuits. The VHDLAMS description is compiled into labeled hybrid Petri nets (LHPN...2007
14 Myers, Chris J.Synthesis of timed circuits based on decompositionAbstract-This paper presents a decomposition-based method for timed circuit design that is capable of significantly reducing the cost of synthesis. In particular, this method synthesizes each output individually. It begins by contracting the timed signal transition graph (STG) to include only transi...2007
