  • 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 ...
  • Poocharoen, Panupat; Magana, Mario E. (IEEE - Institute of Electrical and Electronics Engineers, 2012-10-16)
    In this paper, we propose an improved version of the min-sum algorithm for low density parity check (LDPC) code decoding, which we call “adaptive normalized BP-based” algorithm. Our decoder provides a compromise solution ...
  • Cheng, Li-Jing; Liu, Lei (Optical Society of America, 2013-11-18)
    We report optical modulation of continuous terahertz (THz) wave in the frequency range of 570-600 GHz using photo-induced reconfigurable patterns on a silicon wafer. The patterns were implemented using programmable il ...
  • Zheng, Youyi; Tai, Chiew-Lan; Zhang, Eugene; Xu, Pengfei (IEEE - Institute of Electrical and Electronics Engineers, 2013-07)
    This paper introduces a simple yet effective shape analysis mechanism for geometry processing. Unlike traditional shape analysis techniques which compute descriptors per surface point up to certain neighborhoods, we int ...
  • Borradaile, Glencora; Demaine, Erik D.; Tazari, Siamak (Springer, 2014-02)
    We present the first polynomial-time approximation schemes (PTASes) for the following subset-connectivity problems in edge-weighted graphs of bounded genus: Steiner tree, low-connectivity survivable-network design, an ...
  • 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.
  • Campbell, John L.; Rustad, Lindsey E.; Porter, John H.; Taylor, Jeffrey R.; Dereszynski, Ethan W.; Shanley, James B.; Gries, Corinna; Henshaw, Donald L.; Martin, Mary E.; Sheldon, wade M.; Boose, Emery R. (American Institute of Biological Sciences, 2013-07)
    Sensor networks are revolutionizing environmental monitoring by producing massive quantities of data that are being made publically available in near real time. These data streams pose a challenge for ecologists because ...
  • 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 ...
  • Wanalertlak, Weetit; Lee, Ben; Yu, Chansu; Kim, Myungchul; Park, Seung-Min; Kim, Won-Tae (Springer, 2013-12)
    Wireless LANs (WLANs) have been widely adopted and are more convenient as they are inter-connected as wireless campus networks and wireless mesh networks. However, time-sensitive multimedia applications, which have b ...
  • Cheung, S.-C. S.; Nguyen, Thinh (Springer, 2007-12-11)
    One of the most important problems facing any distributed application over a heterogeneous network is the protection of private sensitive information in local terminals. A subfield of cryptography called secure multipar ...
  • 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 ...
