  • Shih, S.; Keir, P.D.; Hitt, J. C.; Wager, J. F. (American Institute of Physics, 1996-09-23)
    Offset is observed in the charge–voltage (Q–V) or internal charge–phosphor field (Q–Fp) characteristics of certain alternating-current thin-film electroluminescent (ACTFEL) devices. This offset arises from a displaceme ...
  • Albright, Ryan K.; Goska, Benjamin J.; Hagen, Tory M.; Chi, Mike Y.; Cauwenbergh, G.; Chiang, Patrick Y. (Institute of Electrical and Electronics Engineers, 2011)
    A wearable, multi-modal sensor is presented that can non-invasively monitor a patient’s activity level and heart function concurrently for more than a week. The 4in² sensor incorporates both a non-contact heartrate se ...
  • Choi, Kwonhue; Liu, Huaping (IEEE-Institute of Electrical and Electronics Engineers, 2012-04)
    Polyphase complex scrambling patterns are designed to extend the zero-correlation zone (ZCZ) of a family of user spreading sequences, called properly scrambled Walsh-Hadamard (PSW) codes, recently proposed for quasi-sync ...
  • Budd, Timothy (IEEE, 2001-08)
    The digital battery's per-use pricing model may be our best hope for protecting artists' livelihoods, generating meaningful usage statistics, and ensuring consumer privacy.
  • Natarajan, Sriraam; Tadepalli, Prasad; Fern, Alan (Springer, 2012-08)
    Building intelligent assistants has been a long-cherished goal of AI, and many were built and fine-tuned to specific application domains. In recent work, a domain-independent decision-theoretic model of assistance was pr ...
  • Keir, P. D.; Le, H.; Thuemler, R. L.; Hitt, J. C.; Wager, J. F. (American Institute of Physics, 1996-10-14)
    Anomalous charge-voltage (Q-V) characteristics are observed for several types of alternating-current thin-film electroluminescent (ACTFEL) devices. These Q-V curves are anomalous because conduction charge flows in these ...
  • Wang, Alan X. (Society of Photo-Optical Instrumentation Engineers (SPIE), 2012-07-18)
    The performance of metallic-hollow-core-waveguides (MHCWs) and multimode polymer waveguides (MMPWs) are numerically evaluated using ray-tracing method for complex board level optical interconnects systems such as optical ...
  • Hershberg, Benjamin; Weaver, Skyler; Sobue, Kazuki; Takeuchi, Seiji; Hamashita, Koichi; Moon, Un-Ku (IEEE, 2012-12)
    In this paper the fundamental concept of ring amplification is introduced and explored. Ring amplifiers enable efficient amplification in scaled environments, and possess the benefits of efficient slew-based charging, ...
  • Szymczak, Andrzej; Zhang, Eugene (IEEE-Institute of Electrical and Electronics Engineers, 2012-06)
    In this paper, we introduce a new approach to computing a Morse decomposition of a vector field on a triangulated manifold surface. The basic idea is to convert the input vector field to a piecewise constant (PC) vector ...
  • Ilaria, Liccardi; Ounnas, Asma; Pau, Reena; Massey, Elizabeth; Kinnunen, Paivi; Lewthwaite, Sarah; Midy, Marie-Anne; Sarkar, Chandan (2007)
    The aim of this research is to investigate the role of social networks in computer science education. The Internet shows great potential for enhancing collaboration between people and the role of social software has bec ...
  • Lin, Che-Yun; Subbaraman, Harish; Hosseini, Amir; Wang, Alan X.; Zhu, Liang; Chen, Ray T. (American Institute of Physics, 2012-07-30)
    We demonstrate a four-channel on-chip true-time-delay module based on a photonic crystal waveguide array. Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1-3 mm long photonic crystal ...
  • Bai, Rui; Wang, Jingguang; Xia, Lingli; Zhang, Feng; Yang, Zongren; Hu, Weiwu; Chiang, Patrick (IEEE-Institute of Electrical and Electronics Engineers, 2011-12)
    Current multi-gigahertz ADC performance is limited by the sampling clock timing jitter. This paper describes the effects of clock transition time on the spurious-free dynamic range (SFDR) of a CMOS T/H circuit. A sign ...
  • Scaffidi, Christopher; Chambers, Christopher (Taylor & Francis, 2012)
    The Scratch environment exemplifies a tool+community approach to teaching elementary programming skills, as it includes a website where users can publish, discuss, and organize animations that are programs. To explore th ...
  • Liliental, Z.; Wager, J. F.; Goodnick, S. M. (The American Institute of Physics, 1995-03-01)
    InP/SiO₂ interfaces have been studied by high resolution electron microscopy in cross section, by ellipsometry, and by x-ray photoelectron spectroscopy. The roughness of the interface is shown to vary from 10 to 100 Å pe ...
  • Lany, S.; Zakutayev, A.; Mason, T. O.; Wager, J. F.; Poeppelmeier, K. R.; Perkins, J. D.; Berry, J. J.; Ginley, D. S.; Zunger, A. (American Physical Society, 2012-01-06)
    The microscopic cause of conductivity in transparent conducting oxides like ZnO, In₂O₃, and SnO₂ is generally considered to be a point defect mechanism in the bulk, involving intrinsic lattice defects, extrinsic dopants, ...
  • Edmunds, Matt; Laramee, Robert S.; Chen, Guoning; Max, Nelson; Zhang, Eugene; Ware, Colin (Elsevier, 2012-12)
    With increasing computing power, it is possible to process more complex fluid simulations. However, a gap between increasing data size and our ability to visualize them still remains. Despite the great amount of progres ...
  • Holzmann, Gerard J.; Joshi, Rajeev; Groce, Alex (IEEE Computer Society, 2010-12-10)
    The range of verification problems that can be solved with logic model checking tools has increased significantly in the last few decades. This increase in capability is based on algorithmic advances and new theoretical ...
  • Luckey, Markus; Erwig, Martin; Engels, Gregor (Elsevier, 2012-10)
    Using spreadsheets is the preferred method to calculate, display or store anything that fits into a table-like structure. They are often used by end users to create applications, although they have one critical drawback ...
  • Li, W.; Wang, T.; Cao, J.; Temes, G. C. (The Institution of Engineering and Technology, 2012-05-24)
    Two large-resistance realisation schemes are proposed using switched-capacitor circuits. The equivalent resistance of the array realisation increases as the third power of the number of capacitor pairs, and that of th ...
  • Maghari, Nima; Moon, Un-Ku (IEEE-Institute of Electrical and Electronics Engineers, 2011-12)
    This paper describes a new analog-to-digital converter based on the traditional dual-slope ADC operation. With a small modification to the discharging phase of the dual-slope ADC, first-order quantization noise shaping i ...
