  • Burgess, Ian B.; Zhang, Yinan; McCutcheon, Murray W.; Rodriguez, Alejandro W.; Bravo-Abad, Jorge; Johnson, Steven G.; Loncar, Marko (Optical Society of America, 2009-10)
    We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear ...
  • Chatzigeorgiou, Dimitrios; Youcef-Toumi, Kamal; Ben-Mansour, Rached (Institute of Electrical and Electronics Engineers (IEEE), 2014-03)
    Leakage is the major factor for unaccounted losses in every pipe network around the world (oil, gas, or water). In most cases, the deleterious effects associated with the occurrence of leaks may present serious economical ...
  • Comfoltey, E. Nicholas; Shapiro, Michael; Sirigiri, Jagadishwar R.; Temkin, Richard J. (Institute of Electrical and Electronics Engineers, 2009-08)
    We report on the design and cold test validation of an overmoded TWT capable of producing power in excess of 100 Watts in the W-band and above. The TWT operates in the TM31 mode of a rectangular cavity and has transverse ...
  • Zhao, Zhenlong; Iloeje, Chukwunwike Ogbonnia; Chen, Tianjiao; Ghoniem, Ahmed F (Elsevier, 2013-12)
    Chemical-looping combustion (CLC) is a novel and promising option for several applications including carbon capture (CC), fuel reforming, H2 generation, etc. Previous studies demonstrated the feasibility of performing CLC ...

  • Xia, Cassandra T.; Maes, Patricia (Association for Computing Machinery, 2013-03)
    Fifty years ago, Doug Engelbart created a conceptual framework for augmenting human intellect in the context of problem-solving. We expand upon Engelbart's framework and use his concepts of process hierarchies and artifact ...
  • Gilbertson, Eric W.; Hover, Franz S.; Arellano, Jose; Freeman, Bryan (ASME International, 2011-06)
    Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valve assemblies (GLV). One failure mode occurs when the GLV check valve fails and product passes into the well annulus, potentially reaching ...
  • Zheng, Lizhong; Huang, Shao-Lun; Blankenship, Yufei (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    In information theory, in order to maximize the total throughput, it is required that the codebook has an empirical distribution that maximizes the mutual information over the channel. In coding theory, however, most codes ...
  • Elbaggari, Khalil M.; Afridi, Khurram K.; Perreault, David J.; Santiago-Gonzalez, Juan Anton (Institute of Electrical and Electronics Engineers (IEEE), 2015-02)
    Resonant rectifiers have important applications in very-high-frequency (VHF) power conversion systems, including dc-dc converters, wireless power transfer systems, and energy recovery circuits for radio-frequency systems. ...
  • Song, Chaoyang; Luo, Jianxi; Hölttä-Otto, Katja; Otto, Kevin; Seering, Warren Paul (ASME International, 2015-08)
    Crowdfunding is an emerging phenomenon where entrepreneurs publicize their product concepts to raise development funding and collect design feedback directly from potential supporters. Many innovative products have raised ...
  • McNew, John M.; Forghani Oozroody, Mojtaba; Hoehener, Daniel Andreas; Del Vecchio, Domitilla (Institute of Electrical and Electronics Engineers (IEEE), 2015-12)
    In this paper, we consider the problem of designing in-vehicle driver-assist systems that warn or override the driver to prevent collisions with a guaranteed probability. The probabilistic nature of the problem naturally ...
  • Forghani Oozroody, Mojtaba; McNew, John M.; Hoehener, Daniel; Del Vecchio, Domitilla (Institute of Electrical and Electronics Engineers (IEEE), 2015-11-13)
    This document contains the statements and proofs of the main theoretical results presented in the paper by the same authors with the title \Design of driver-assist system under probabilistic safety specifications near stop ...
  • Hassan, Gimba; Perreault, David J.; Keim, Thomas A. (Institute of Electrical and Electronics Engineers (IEEE), 2005-01)
    The push to introduce dual-voltage (42 V/14 V) automotive electrical systems necessitates power generation solutions capable of supplying power to multiple outputs. A number of approaches for implementing dual-voltage ...
  • Zheng, H.; Ooi, Boon Hooi; Cho, Wonjoon; Dao, M. H.; Tkalich, P.; Patrikalakis, Nicholas M. (American Institute of Physics, 2010-05)
    Due to the highly non-linear and dynamical nature of oceanic phenomena, the predictive capability of various ocean models depends on the availability of operational data. A practical method to improve the accuracy of the ...
  • Sievers, Martin; Lienhard, John H. (Taylor & Francis, 2013-01)
    Flat-plate heat exchangers are examined for use as dehumidifiers in humidification–dehumidification (HDH) desalination systems. The temperature and humidity ratio differences that drive mass transfer are considerably higher ...
  • Vaucelle, Catherine Nicole; Bonanni, Leonardo Amerigo; Ishii, Hiroshi (Association for Computing Machinery, 2009-04)
    Touch is fundamental to our emotional well-being. Medical science is starting to understand and develop touch-based therapies for autism spectrum, mood, anxiety and borderline disorders. Based on the most promising touch ...
  • Pejawar-Gaddy, Sharmila; Kovacs, James M.; Barouch, Dan H.; Chen, Bing; Irvine, Darrell J. (American Chemical Society (ACS), 2014-07)
    Immunization strategies that elicit antibodies capable of neutralizing diverse virus strains will likely be an important part of a successful vaccine against HIV. However, strategies to promote robust humoral responses ...
  • Pejawar Gaddy, Sharmila; Kovacs, J.; Barouch, D.; Chen, B.; Irvine, Darrell J. (BioMed Central Ltd., 2012-09)
    Background: Immunization strategies that elicit antibodies capable of neutralizing diverse strains of the virus will likely be an important part of a successful vaccine against HIV. The envelope trimer is the only ...
  • Sinangil, Mahmut E.; Yip, Marcus; Qazi, Masood; Rithe, Rahul; Kwong, Joyce; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers (IEEE), 2012-08)
