      In this paper, we study transmission techniques for broadcast channels with a single transmitter and multiple receivers. The transmitter is assumed to be equipped with multiple antennas. Further, each receiver is interested ...
    • Buckminsterfullerene purification and buckminsterfullerene film characterization 

      Averitt, Richard Douglas (1994)
      A method is described which utilizes the difference in vapor pressure between C$\sb{60}$ and heavier fullerenes to produce C$\sb{60}$ powder with a purity of 99.97%. Using the material from this process allows for the ...
    • Building a Control-flow Graph from Scheduled Assembly Code 

      Cooper, Keith D.; Harvey, Timothy J.; Waterman, Todd (2002-02-01)
      A variety of applications have arisen where it is worthwhile to apply code optimizations directly to the machine code (or assembly code) produced by a compiler. These include link-time whole-program analysis and optimization, ...
    • Building a map for robot path planning by fusing video images and laser rangefinder data 

      Reynolds, Steven Lamar (1993)
      This thesis describes algorithms that fuse the data from a single video camera and a laser rangefinder. By merging information from these sensors, the algorithms build a digital map of the local environment for a robot to ...
    • Building Adaptive Compilers 

      Almagor, L.; Cooper, Keith D.; Grosul, Alexander; Harvey, Timothy J.; Reeves, Steven W.; Subramanian, Devika; Torczon, Linda; Waterman, Todd (2005-01-29)
      Traditional compilers treat all programs equally -that is, they apply the same set of techniques to every program that they compile. Compilers that adapt their behavior to fit specific input programs can produce better ...
    • Building Bridges: Leveraging Interdisciplinary Collaborations in the Development of Biomaterials to Meet Clinical Needs 

      Fong, Eliza L.S.; Watson, Brendan M.; Kasper, F. Kurtis; Mikos, Antonios G. (2012)
      Our laboratory at Rice University has forged numerous collaborations with clinicians and basic scientists over the years to advance the development of novel biomaterials and the modification of existing materials to meet ...
    • Building Incentives into Tor 

      Dingledine, Roger; Ngan, Tsuen-Wan "Johnny"; Wallach, Dan S. (2008-11-12)
      Distributed anonymous communication networks like Tor depend on volunteers to donate their resources. However, the efforts of Tor volunteers have not grown as fast as the demands on the Tor network. We explore techniques ...
    • Bursting, beating, and chaotic modes in mathematical models of the R15 cell in Aplysia 

      Canavier, Carmen Castro (1989)
      Chaotic regimes have been observed experimentally in neurons as well as in deterministic neuronal models. The bursting R15 cell in the abdominal ganglion of Aplysia has been the subject of extensive mathematical modeling. ...
    • C++.T Formalization in Isar 

      Siek, Jeremy G.; Taha, Walid (2005-12-16)
      A formal account of C++ templates, including the compile-time and run-time semantics. The main result is a proof of type safety. The proof is written in the Isar proof language and can be mechanically verified using the ...
    • Cache Coherence Using Local Knowledge 

      Darnell, Ervan (1995-04-01)
      Hiding memory latency is critical in modern machines. Typically, machines have used cache and addressed the ensuing cache coherence problem with hardware or VM-based strategies that rely on global inter-cache communicati ...
    • Cache management in scalable network servers 

      Pai, Vivek Sadananda (2000)
      For many users, the perceived speed of computing is increasingly dependent on the performance of network server systems, underscoring the need for high performance servers. Cost-effective scalable network servers can be ...
