  • Braoudakis, Spyridon; Bestavros, Azer (Boston University Computer Science Department, 1994)
    Various concurrency control algorithms differ in the time when conflicts are detected, and in the way they are resolved. In that respect, the Pessimistic and Optimistic Concurrency Control (PCC and OCC) alternatives represent ...
  • Harchol-Balter, Mor; Crovella, Mark E.; Murta, Cristina D. (Boston University Computer Science Department, 1997-10-31)
    We examine the question of whether to employ the first-come-first-served (FCFS) discipline or the processor-sharing (PS) discipline at the hosts in a distributed server system. We are interested in the case in which service ...
  • Wood, Richard J.; Schwartz, Eric L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-10)
    Shear has been known to exist for many years in the topographic structure of prirnary visual cortex, but has received little attention in the modeling literature. Although the topographic map of V1 is largely conformal ...
  • Tal, D.; Schwartz, E. L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1996-11)
    Optical imaging methods have revealed the spatial arrangement of orientation columns across striate cortex, usually summarized in terms of two measurements at each cortical location: (i) a "best" stimulus orientation, ...
  • Raizada, Rajeev D.S.; Grossberg, Stephen (Boston University Computer Science Department, 2001-12-03)
    One of the most exciting and open research frontiers in neuroscience is that of seeking to understand the functional roles of the layers of cerebral cortex. New experimental techniques for probing the laminar circuitry of ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2006-10)
    A key goal of computational neuroscience is to link brain mechanisms to behavioral functions. The present article describes recent progress towards explaining how laminar neocortical circuits give rise to biological ...
  • Gabay, Yarom; Kfoury, Assaf J. (Boston University Computer Science Department, 2006-12-15)
    Weak references provide the programmer with limited control over the process of memory management. By using them, a programmer can make decisions based on previous actions that are taken by the garbage collector. Although ...
  • Wu, Zheng; Hristov, Nickolay I.; Hedrick, Tyson L.; Kunz, Thomas H.; Betke, Margrit (Boston University Computer Science Department, 2009-09)
    We propose a multi-object multi-camera framework for tracking large numbers of tightly-spaced objects that rapidly move in three dimensions. We formulate the problem of finding correspondences across multiple views as a ...
  • Tian, Tai-Peng; Li, Rui; Sclaroff, Stan (Boston University Computer Science Department, 2005-07-28)
    Particle filtering is a popular method used in systems for tracking human body pose in video. One key difficulty in using particle filtering is caused by the curse of dimensionality: generally a very large number of particles ...
  • Wu, Zheng; Hristov, Nickolay; Swartz, Sharon; Kunz, Thomas; Betke, Margrit (CS Department, Boston University, 2010-09-06)
    We developed two methods for tracking multiple objects using several camera views. The methods use the Multiple Hypothesis Tracking (MHT) framework to solve both the across-view data association problem (i.e., finding ...
  • Londoño, Jorge; Bestavros, Azer; Laoutaris, Nikolaos (Boston University Computer Science Department, 2009-07-29)
    We propose Trade & Cap (T&C), an economics-inspired mechanism that incentivizes users to voluntarily coordinate their consumption of the bandwidth of a shared resource (e.g., a DSLAM link) so as to converge on what they ...
  • Duarte, Fernando; Mattos, Bernardo; Bestavros, Azer; Almeida, Virgilio; Almeida, Jussara (Boston University Computer Science Department, 2006-12-15)
    We present a thorough characterization of the access patterns in blogspace -- a fast-growing constituent of the content available through the Internet -- which comprises a rich interconnected web of blog postings and ...
  • Rosales, Rómer; Sclaroff, Stan (Boston University Computer Science Department, 1999-03-09)
    A combined 2D, 3D approach is presented that allows for robust tracking of moving people and recognition of actions. It is assumed that the system observes multiple moving objects via a single, uncalibrated video camera. ...
  • Martin, Michael (The New Zealand Association of Rationalists and Humanists, 1996-09)
  • Gelfand, Yevgeniy; Rodriguez, Alfredo; Benson, Gary (Oxford University Press, 2006-12-14)
    Tandem repeats in DNA have been under intensive study for many years, first, as a consequence of their usefulness as genomic markers and DNA fingerprints and more recently as their role in human disease and regulatory ...
  • Murphy, Kevin F.; Adams, Rhys M.; Wang, Xiao; Balázsi, Gábor; Collins, James J. (Oxford University Press, 2010-03-08)
    Synthetic gene networks can be used to control gene expression and cellular phenotypes in a variety of applications. In many instances, however, such networks can behave unreliably due to gene expression noise. Accordingly, ...
  • Samz, Charles (International Center for East Asian Archaeology and Cultural History, Boston University, 1971)
  • Sullivan, James C.; Wolenski, Francis S.; Reitzel, Adam M.; French, Courtney E.; Traylor-Knowles, Nikki; Gilmore, Thomas D.; Finnerty, John R. (Public Library of Science, 2009-10-6)
    BACKGROUND. NF-κB is an evolutionarily conserved transcription factor that controls the expression of genes involved in many key organismal processes, including innate immunity, development, and stress responses. NF-κB ...
  • Jacobs, J. Pieter; Bullock, Daniel (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-10)
    Prior reports indicated a non-linear increase in key overlap times (KOTs) as tempo slows for scales/arpeggios performed at internote intervals (INIs) of I00-1000 ms. Simulations illustrate that this function can be explained ...
  • Medina, A.; Salamatian, K.; Taft, N.; Matta, I.; Diot, C. (Boston University Computer Science Department, 2004-03-01)
    Accurate knowledge of traffic demands in a communication network enables or enhances a variety of traffic engineering and network management tasks of paramount importance for operational networks. Directly measuring a ...
