    High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power ...
  • Rajaee, Omid; Moon, Un-Ku (IEEE, 2013-02)
    A noise-shaped pipelined ADC is presented in this paper. A minimal complexity ΔΣ modulator in the first two sub-ADCs and residue feedback in the latter stages lead to high-order noise shaping. This also leads to reduce ...
  • Zhang, Xingyu; Lee, Beomsuk; Lin, Che-yun; Wang, Alan X.; Hosseini, Amir; Chen, Ray T. (IEEE-Institute of Electrical and Electronics Engineers, 2012-12)
    In this paper, we present the design, fabrication and characterization of a traveling wave directional coupler modulator based on electro-optic polymer, which is able to provide both high linearity and broad bandwidth. ...
  • Douglas, A. A.; Wager, J. F.; Morton, D. C.; Koh, J. B.; Hogh, C. P. (The American Insitute of Physics, 1993-07-12)
    Hot electron luminescence experiments are performed on ZnS alternating-current thin-film electroluminescent (ACTFEL) devices in order to determine the extent to which the electron distribution is heated. The luminescence ...
  • Lawrance, Joseph; Bogart, Christopher; Burnett, Margaret; Bellamy, Rachel; Rector, Kyle; Fleming, Scott D. (IEEE, 2013-02)
    Many theories of human debugging rely on complex mental constructs that offer little practical advice to builders of software engineering tools. Although hypotheses are important in debugging, a theory of navigation adds ...
  • Zhang, Heng; Liu, Huaping; Quan, Shuxue (International Soceity for Optics and Photonics (SPIE), 2012-07)
    A method for preferred color reproduction with a psychophysical study based upon a real-life scene demonstrated application is presented. A color correction matrix optimization algorithm is first introduced which applies ...
  • Qiao, Tianzhu; Liu, Huaping (IEEE - Institute of Electrical and Electronics Engineers, 2013-07)
    Estimation accuracy and computational complexity are two major areas of consideration for localization system design. For time-of-arrival based systems, the 1st-order method of moments (MOM) least-square (LS) estimato ...
  • Fleming, Scott D.; Scaffidi, Chris; Piorkowski, David; Burnett, Margaret; Bellamy, Rachel; Lawrance, Joseph; Kwan, Irwin (Association for Computing Machinery, 2013-03)
    Theories of human behavior are an important but largely untapped resource for software engineering research. They facilitate understanding of human developers’ needs and activities, and thus can serve as a valuable res ...
  • Song, Han; Spencer, Jeremy; Jander, Albrecht; Nielsen, Jeffrey; Stasiak, James; Kasperchik, Vladek; Dhagat, Pallavi (American Institute of Physics Publishing, 2014-05-07)
    3-D printing processes, which use drop-on-demand inkjet printheads, have great potential in designing and prototyping magnetic materials. Unlike conventional deposition and lithography, magnetic particles in the printi ...
  • Pham, Tuan; Jones, Julia; Metoyer, Ronald; Swanson, Frederick; Pabst, Robert (Ecological Society of America, 2013-09-25)
    Long-term ecological data are crucial in helping ecologists understand ecosystem function and environmental change. Nevertheless, these kinds of data sets are difficult to analyze because they are usually large, multiv ...
  • Wu, J. C.; Wybourne, M. N.; Yindeepol, W.; Weisshaar, A.; Goodnick, S. M. (American Institute of Physics, 1991-07-01)
    Narrow channel devices were fabricated using a split-gate high electron mobility transistor structure in which electrons are forced through a double-bend discontinuity. The low-temperature conductance shows a number of p ...
  • Abu-Dayah, A.; Kobayashi, S.; Wager, J. F. (The American Institute of Physics, 1993-02-15)
    The internal charge versus phosphor field (Q-Fp) technique is proposed as a method for characterization of the electrical properties of alternating-current thin-film electroluminescent (ACTFEL) devices. Q-Fp analysis pro ...

    See article for Abstract.
  • Buford, Benjamin; Dhagat, Pallavi; Jander, Albrecht (American Institute of Physics Publishing, 2014-05-07)
    A method for measuring the magnetostriction of thin films using a vibrating sample magnetometer is described. We describe the design of a custom sample holder to apply an adjustable bending stress to the sample during ...
  • Cotilla-Sanchez, Eduardo; Hines, Paul D. H.; Barrows, Clayton; Blumsack, Seth; Patel, Mahendra (IEEE - Institute of Electrical and Electronics Engineers, 2013-11)
    Identifying coherent sub-graphs in networks is important in many applications. In power systems, large systems are divided into areas and zones to aid in planning and control applications. But not every partitioning i ...
  • Chen, C.-H.; Jung, Y.; Ceballos, J. L.; Temes, G. C. (IEEE - Institute of Electrical and Electronics Engineers, 2013-01-03)
    Extended-counting A/D converters are proposed which achieve a high accuracy by performing the conversion in several cycles. During the first cycle, the circuit performs as an incremental ADC, while during the remainin ...
  • Weaver, Skyler; Hershberg, Benjamin; Hanumolu, Pavan Kumar; Moon, Un-Ku (Springer, 2012-10)
    A ones adder is an important circuit block that is required in many varying applications. This work proposes a design that largely relies on passive transmission-gate multiplexers. Many variations are suggested that can ...
