      Felleisen, Matthias; Findler, Robert Bruce (2005-08-25)
      Programs should consist of off-the-shelf, interchangeable, black-box components that are produced by a network of independent software companies. These components should not only come with type signatures but also with ...
    • Behavioral Software Contracts 

      Findler, Robert Bruce (2002-04-01)
      To sustain a market for software components, component producers and consumers must agree on contracts. These contracts must specify each party’s obligations. To ensure that both sides meet their obligations, they must ...

      This paper describes the benefits associated with student and faculty participation in DSP design-related activities that fall outside of the usual university course requirements. It will also describe industry's role in ...
    • BER of optical communication system using fiber source 

      Nguyen, Lim; Aazhang, Behnaam; Young, James F. (1995-11-20)
      We analyze the bit-error rate (BER) of an optical communication system using the superfluorescent fiber source (SFS). The counting statistics of thermal light give improved performance relative to the Gaussian statistics ...
    • Beyond Interference Avoidance: Distributed Sun-network Scheduling in Wireless Networks with Local Views 

      Santacruz, Pedro (2013-09-16)
      In most wireless networks, nodes have only limited local information about the state of the network, which includes connectivity and channel state information. With limited local information about the network, each node’s ...
    • Beyond Time Frequency Analysis: Energy Densities in One and Many Dimensions 

      Baraniuk, Richard G. (1994-04-01)
      Given a unitary operator <i>A</i> representing a physical quantity of interest, we employ concepts from group representation theory to define two natural signal energy densities for <i>A</i>. The first is invariant to ...
    • Beyond Time Frequency Analysis: Energy Densities in One and Many Dimensions 

      Baraniuk, Richard G. (1998-09-01)
      Given a unitary operator A representing a physical quantity of interest, we employ concepts from group representation theory to define two natural signal energy densities for A. The first is invariant to A and proves ...
    • Bi-Phasic photocatalytic particles prepared by sequential layer depositions for water cleaning and purification 

      Gomez, Virginia; Rome, Bertrand; Barron, Andrew R.; Dunnill, Charles W. (2016)
      Bi-phasic photocatalyic particles have been prepared in the form of Janus-like structures (bi-phasic materials with two distinct properties on opposing sides of the particle) using a new synthetic procedure consisting of ...
    • Bifunctional Luminomagnetic Rare-Earth Nanorods for High-Contrast Bioimaging Nanoprobes 

      Gupta, Bipin Kumar; Singh, Satbir; Kumar, Pawan; Lee, Yean; Kedawat, Garima; Narayanan, Tharangattu N.; Vithayathil, Sajna Antony; Ge, Liehui; Zhan, Xiaobo; Gupta, Sarika; Martí, Angel A.; Vajtai, Robert; Ajayan, Pulickel M.; Kaipparettu, Benny Abraham (2016)
      Nanoparticles exhibiting both magnetic and luminescent properties are need of the hour for many biological applications. A single compound exhibiting this combination of properties is uncommon. Herein, we report a strategy ...
    • The Billion Cell Construct: Will Three-Dimensional Printing Get Us There? 

      Miller, Jordan S. (2014)
      How structure relates to function—across spatial scales, from the single molecule to the whole organism—is a central theme in biology. Bioengineers, however, wrestle with the converse question: will function follow form? ...
    • Binaural localization using interaural cues 

      Dabak, Anand Ganesh (1990)
      Major nuclei of the superior olivary complex--the lateral superior olive (LSO) and the medial superior olive (MSO) are presumed to play a major role in the localization of sound signals using interaural level and interaural ...
    • Binding Modes of Peptidomimetics Designed to Inhibit STAT3 

      Dhanik, Ankur; McMurray, John S.; Kavraki, Lydia E. (2012)
