  • Wei, Ermin; Ozdaglar, Asuman E.; Jadbabaie, Ali (Institute of Electrical and Electronics Engineers, 2010-12)
    Most existing work uses dual decomposition and subgradient methods to solve Network Utility Maximization (NUM) problems in a distributed manner, which suffer from slow rate of convergence properties. This work develops an ...
  • Jiang, Libin; Shah, Devavrat; Shin, Jinwoo; Walrand, Jean (Institute of Electrical and Electronics Engineers, 2010-11)
    This paper provides proofs of the rate stability, Harris recurrence, and ε-optimality of carrier sense multiple access (CSMA) algorithms where the random access (or backoff) parameter of each node is adjusted dynamically. ...
  • Boerkoel, James; Durfee, Edmund H. (Association for the Advancement of Artificial Intelligence, 2013-05)
    This research focuses on building foundational algorithms for scheduling agents that assist people in managing their activities in environments where tempo and complex activity interdependencies outstrip people's cognitive ...
  • Misra, Vinith; Goyal, Vivek K.; Varshney, Lav Raj (Institute of Electrical and Electronics Engineers (IEEE), 2011-07)
    Communication of quantized information is frequently followed by a computation. We consider situations of distributed functional scalar quantization: distributed scalar quantization of (possibly correlated) sources followed ...
  • Dimarogonas, Dimos V.; Frazzoli, Emilio; Johansson, Karl H. (Institute of Electrical and Electronic Engineers, 2010-12)
    It is desirable to limit the amount of communication and computation generated by each agent in a large multi-agent system. Event- and self-triggered control strategies have been recently proposed as alternatives to ...
  • Modiano, Eytan H.; Le, Long Bao; Lee, Hyang-Won (Institute of Electrical and Electronics Engineers, 2009-10)
    We consider throughput-optimal power allocation in multi-hop wireless networks. The study of this problem has been limited due to the non-convexity of the underlying optimization problems, that prohibits an efficient ...
  • Wongpiromsarn, Tichakorn; Uthaicharoenpong, Tawit; Wang, Yu; Frazzoli, Emilio; Wang, Danwei (Institute of Electrical and Electronics Engineers (IEEE), 2012-09)
    We propose a distributed algorithm for controlling traffic signals. Our algorithm is adapted from backpressure routing, which has been mainly applied to communication and power networks. We formally prove that our algorithm ...
  • Lapinski, Michael Tomasz; Berkson, Eric; Gill, Thomas; Reinold, Mike; Paradiso, Joseph A. (Institute of Electrical and Electronics Engineers, 2009-09)
    This paper introduces a compact, wireless, wearable system that measures signals indicative of forces, torques and other descriptive and evaluative features that the human body undergoes during bursts of extreme physical ...
  • Paltsev, Sergey; Rausch, Sebastian; Reilly, John M; Metcalf, Gilbert E (Berkeley Electronic Press, 2010-07)
    We analyze the distributional and efficiency impacts of different allowance allocation schemes motivated by recently proposed U.S. climate legislation for a national cap and trade system using a new dynamic computable ...
  • Allaire, Douglas L.; Willcox, Karen E. (Elsevier, 2010-06)
    Among the uses for global sensitivity analysis is factor prioritization. A key assumption for this is that a given factor can, through further research, be fixed to some point on its domain. For factors containing epistemic ...
  • Nshimyimana, Jean Pierre; Ekklesia, E.; Shanahan, Peter; Chua, L. H. C.; Thompson, Janelle Renee (John Wiley & Sons, Inc, 2014-05)
    Aims: The study goals were to determine the relationship between faecal indicator bacteria (FIB), the HF183 marker and land use, and the phylogenetic diversity of HF183 marker sequences in a tropical urban watershed. Methods ...
  • Altshuler, David (Public Library of Science, 2014-07)
    Exome sequencing studies in complex diseases are challenged by the allelic heterogeneity, large number and modest effect sizes of associated variants on disease risk and the presence of large numbers of neutral variants, ...
  • Preheim, Sarah Pacocha; Perrotta, Allison Rose; Martin-Platero, Antonio M.; Gupta, Anika; Alm, Eric J. (American Society for Microbiology, 2013-08)
    16S rRNA sequencing, commonly used to survey microbial communities, begins by grouping individual reads into operational taxonomic units (OTUs). There are two major challenges in calling OTUs: identifying bacterial population ...
  • Kelley, Luke Zoltan; Ramirez-Ruiz, Enrico; Zemp, Marcel; Diemand, Jürg; Mandel, Ilya (Institute of Physics/American Astronomical Society, 2010-12)
    Merging compact binaries are the most viable and best-studied candidates for gravitational-wave (GW) detection by the fully operational network of ground-based observatories. In anticipation of the first detections, the ...
  • Ferrari, Raffaele; Wunsch, Carl (Co-Action Publishing, 2010-03)
    Understanding of the major sources, sinks, and reservoirs of energy in the ocean is briefly updated in a diagram. The nature of the dominant kinetic energy reservoir, that of the balanced variablity, is then found to be ...
  • De Simone, Andrea; Salem, Michael P. (American Physical Society, 2010-04)
    Our Universe may be contained in one among a diverging number of bubbles that nucleate within an eternally inflating multiverse. A promising measure to regulate the diverging spacetime volume of such a multiverse is the ...
  • Schuh, Christopher A.; Rodney, David (American Physical Society, 2009-06)
    The potential energy landscape of a flowing metallic glass is revealed using the activation-relaxation technique. For a two-dimensional Lennard-Jones system initially deformed into a steady-state condition through quasistatic ...
  • Song, Yale; Morency, Louis-Philippe; Davis, Randall (Institute of Electrical and Electronics Engineers (IEEE), 2013-04)
    Many real-world face and gesture datasets are by nature imbalanced across classes. Conventional statistical learning models (e.g., SVM, HMM, CRY), however, are sensitive to imbalanced datasets. In this paper we show how ...
  • Church, Matthew J.; Wai, Brenner; Karl, David M.; DeLong, Edward (John Wiley & Sons, Inc., 2010-03)
    Planktonic Crenarchaea are thought to play a key role in chemolithotrophic ammonia oxidation, a critical step of the marine nitrogen (N) cycle. In this study, we examined the spatial distributions of ammonia-oxidizing ...
  • Gentine, Pierre; Entekhabi, Dara; Polcher, Jan (American Meteorological Society, 2011-12)
    The components of the land surface energy balance respond to periodic incoming radiation forcing with different amplitude and phase characteristics. Evaporative fraction (EF), the ratio of latent heat to available energy ...
