  • Riga, N.; Matta, I.; Medina, A.; Partridge, C.; Redi, J. (Boston University Computer Science Department, 2007)
    We present a transport protocol whose goal is to reduce power consumption without compromising delivery requirements of applications. To meet its goal of energy efficiency, our transport protocol (1) contains mechanisms ...
  • Sweha, Raymond; Bestavros, Azer; Matta, Ibrahim (Computer Science Department, Boston University, 2012-06-30)
    When it was first introduced a decade ago, Tor, the anonymous onion routing protocol, aimed at providing anonymity for latency-sensitive applications, such as web-browsing, as opposed to bandwidth-intensive applications, ...
  • Reyzin, Leonid (Boston University Computer Science Department, 2007-09-20)
    A secure sketch (defined by Dodis et al.) is an algorithm that on an input w produces an output s such that w can be reconstructed given its noisy version w' and s. Security is defined in terms of two parameters m and m˜ : ...
  • Klitgord, Niels; Segrè, Daniel (Public Library of Science, 2010-11-18)
    Interactions between microbial species are sometimes mediated by the exchange of small molecules, secreted by one species and metabolized by another. Both one-way (commensal) and two-way (mutualistic) interactions may ...
  • Tiuryn, Jerzy (Boston University Computer Science Department, 1995-02)
    Two polymorphic types σ and τ are said to be bicoercible if there is a coercion from σ to τ and conversely. We give a complete equational axiomatization of bicoercible types and prove that the relation of bicoercibility ...
  • Bullock, Daniel; Contreras-Vidal, José L.; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-02)
    One of the advantages of biological skeleto-motor systems is the opponent muscle design, which in principle makes it possible to achieve facile independent control of joint angle and joint stiffness. Prior analysis of ...
  • Park, Kihong (Boston University Computer Science Department, 1996-07-22)
    One-and two-dimensional cellular automata which are known to be fault-tolerant are very complex. On the other hand, only very simple cellular automata have actually been proven to lack fault-tolerance, i.e., to be mixing. ...
  • Rosales, Rómer; Siddiqui, Matheen; Alon, Jonathan; Sclaroff, Stan (Boston University Computer Science Department, 2001-06)
    An approach for estimating 3D body pose from multiple, uncalibrated views is proposed. First, a mapping from image features to 2D body joint locations is computed using a statistical framework that yields a set of several ...
  • Athitsos, Vassilis; Sclaroff, Stan (Boston University Computer Science Department, 2003-04-01)
    A method is proposed that can generate a ranked list of plausible three-dimensional hand configurations that best match an input image. Hand pose estimation is formulated as an image database indexing problem, where the ...
  • Rosales, Romer; Sclaroff, Stan (Boston University Computer Science Department, 2000-06-10)
    A non-linear supervised learning architecture, the Specialized Mapping Architecture (SMA) and its application to articulated body pose reconstruction from single monocular images is described. The architecture is formed ...
  • Wagner, Robert; Polimeni, Jonathan; Schwartz, Eric (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-12)
    Log-polar image architectures, motivated by the structure of the human visual field, have long been investigated in computer vision for use in estimating motion parameters from an optical flow vector field. Practical ...
  • Sigal, Leonid; Sclaroff, Stan; Athitsos, Vassilis (Boston University Computer Science Department, 1999-12-01)
    A novel approach for real-time skin segmentation in video sequences is described. The approach enables reliable skin segmentation despite wide variation in illumination during tracking. An explicit second order Markov model ...
  • Eriksson, Brian; Crovella, Mark (Computer Science Department, Boston University, 2011-05-12)
    The problem of estimating the intrinsic dimension of a set of points in high dimensional space is a critical issue for a wide range of disciplines, including genomics, finance, and networking. Current estimation techniques ...
  • Samz, Charles (International Center for East Asian Archaeology and Cultural History, Boston University, 1964)
  • Matta, Ibrahim; Bestavros, Azer (Boston University Computer Science Department, 1997-07-30)
    To support the diverse Quality of Service (QoS) requirements of real-time (e.g. audio/video) applications in integrated services networks, several routing algorithms that allow for the reservation of the needed bandwidth ...
  • Lin, Hong Huang; Ray, Surajit; Tongchusak, Songsak; Reinherz, Ellis L; Brusic, Vladimir (BioMed Central, 2008-3-16)
    BACKGROUND: Protein antigens and their specific epitopes are formulation targets for epitope-based vaccines. A number of prediction servers are available for identification of peptides that bind major histocompatibility ...
  • Carpenter, Gail A.; Govindarajan, Krishna (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    A procedure that uses fuzzy ARTMAP and K-Nearest Neighbor (K-NN) categorizers to evaluate intrinsic and extrinsic speaker normalization methods is described. Each classifier is trained on preprocessed, or normalized, vowel ...
  • Zilli, Eric A.; Yoshida, Motoharu; Tahvildari, Babak; Giocomo, Lisa M.; Hasselmo, Michael E. (Public Library of Science, 2009-11-20)
    Models of the hexagonally arrayed spatial activity pattern of grid cell firing in the literature generally fall into two main categories: continuous attractor models or oscillatory interference models. Burak and Fiete ...
  • Simms, Stephanie R.; Parker, Evan; Bey, George J., III; Gallareta Negrón, Tomás (Maney Publishing, 2012-11)
    Excavations at the hilltop site of Escalera al Cielo, located in the Puuc Maya region of Yucatán, Mexico, have uncovered evidence of a planned abandonment at the end of the Terminal Classic period (A.D. 800–950). Six ...
  • Traylor-Knowles, Nikki; Hansen, Ulla; Dubuc, Timothy Q; Martindale, Mark Q; Kaufman, Les; Finnerty, John R (BioMed Central, 2010-4-18)
    BACKGROUND. The transcription factors of the LSF/Grainyhead (GRH) family are characterized by the possession of a distinctive DNA-binding domain that bears no clear relationship to other known DNA-binding domains, with the ...
