    Baruah, Sanjoy; Bestavros, Azer (Boston University Computer Science Department, 1997-05-05)
    There is an increased interest in using broadcast disks to support mobile access to real-time databases. However, previous work has only considered the design of real-time immutable broadcast disks, the contents of which ...
  • Real-Time Restoration of Images Degraded by Uniform Motion Blur in Foveal Active Vision Systems
    Bonmassar, Giorgio; Schwartz, Eric L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-02)
    Foveated, log-polar, or space-variant image architectures provide a high resolution and wide field workspace, while providing a small pixel computation load. These characteristics are ideal for mobile robotic and active ...
  • Real-Time Spatio-Temporal Query Processing in Mobile Ad-Hoc Sensor Networks
    Morcos, Hany; Bestavros, Azer; Matta, Ibrahim (Boston University Computer Science Department, 2006-10-15)
    Personal communication devices are increasingly equipped with sensors that are able to collect and locally store information from their environs. The mobility of users carrying such devices, and hence the mobility of sensor ...
  • A Real-Time Unsupervised Neural Network for the Low-Level Control of a Mobile Robot in a Nonstationary Environment
    Zalana, Eduardo; Gaudiano, Paolo; Coronado, Juan Lopez (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-01)
    This article introduces a real-time, unsupervised neural network that learns to control a two-degree-of-freedom mobile robot in a nonstationary environment. The neural controller, which is termed neural NETwork MObile Robot ...
  • Recent Hegel Literature: General Surveys and the Young Hegel
    Schmidt, James (Telos Press, 2012-07-26)
  • Recent Hegel Literature: The Jena Period and the Phenomenology of Spirit
    Schmidt, James (Telos Press, 2012-07-26)
  • Recognition of 3-D Objects from Multiple 2-D Views by a Self-Organizing Neural Architecture
    Bradski, Gary; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-01)
    The recognition of 3-D objects from sequences of their 2-D views is modeled by a neural architecture, called VIEWNET that uses View Information Encoded With NETworks. VIEWNET illustrates how several types of noise and ...
  • Recognition of Human Action Using Moment-Based Feature
    Rosales, Rómer (Boston University Computer Science Department, 1998-12-04)
    The performance of different classification approaches is evaluated using a view-based approach for motion representation. The view-based approach uses computer vision and image processing techniques to register and process ...
  • Reconstruction and analysis of 3D trajectories of Brazilian free-tailed bats in flight
    Theriault, Diane; Wu, Zheng; Hristov, Nickolay; Swartz, Sharon; Breuer, Kenneth; Kunz, Thomas; Betke, Margrit (CS Department, Boston University, 2010-09-06)
    The Brazilian free-tailed bat, Tadarida brasiliensis, roosts in very large colonies, consisting of hundreds of thousands of individuals. Each night, bats emerge from their day roosts in dense columns in a highly coordinated ...
  • A Recurrent Cooperative/Competitive Field for Segmentation of Magnetic Resonance Brain Imagery
    Worth, Andrew J.; Lehar, Steve; Kennedy, David N. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1991-10)
    The Grey-White Decision Network is introduced as an application of an on-center, off-surround recurrent cooperative/competitive network for segmentation of magnetic resonance imaging (MRI) brain images. The three layer ...
  • Recursive Estimation of Motion and Planar Structure
    Alon, Jonathan; Sclaroff, Stan (Boston University Computer Science Department, 1999-12-01)
    A specialized formulation of Azarbayejani and Pentland's framework for recursive recovery of motion, structure and focal length from feature correspondences tracked through an image sequence is presented. The specialized ...
  • Redistribution of Synaptic Efficacy Supports Stable Pattern Learning in Neural Networks
    Carpenter, Gail; Milenova, Boriana (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-07)
    Markram and Tsodyks, by showing that the elevated synaptic efficacy observed with single-pulse LTP measurements disappears with higher-frequency test pulses, have critically challenged the conventional assumption that LTP ...
