    • Calculating Center-Glass Performance Indices of Windows 

      Wright, John L. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1998)
      Building envelope performance is strongly influenced by solar gain and heat transfer through windows. The majority of this energy gain or loss passes through the center-glass area of the glazing system. Various methods ...

    • Calculating the Solar Heat Gain of Window Frames 

      Wright, John L.; McGowan, Alexander G. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1999)
      It is not practical to measure the solar heat gain of a window frame. It is more practical to do so by calculation. Typically, the frame solar heat gain is a small component of the total or is small in absolute terms so ...

    • Witnessing-condition Heterogeneity and Witnesses’ Versus Investigators’ Confidence in the Accuracy of Witnesses’ Identification Decisions 

      Lindsay, D. Stephen; Nilsen, Elizabeth S.; Read, J. Don (APA, 2000-06)
      Undergraduate participants were tested in 144 pairs, with one member of each pair randomly assigned to a “witness” role and the other to an “:investigator” role. Each witness viewed a target person on video under good or ...
    • Predicting the Mesophases of Copolymer-Nanoparticle Composites 

      Thompson, Russell B.; Ginzburg, Valeriy V.; Matsen, Mark W.; Balazs, Anna C. (American Association for the Advancement of Science, 2001)
      The interactions between mesophase-forming copolymers and nanoscopic par- ticles can lead to highly organized hybrid materials. The morphology of such composites depends not only on the characteristics of the copolymers, ...
    • A Simplified Analysis of Radiant Heat Loss Through Projecting Fenestration Products 

      Wright, John L. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2001)
      Current window analysis algorithms can deal with many features, including low-e coatings and substitute fill gases. These methods were developed for products with planar glazings. Results can be generated for projecting ...

      Thompson, Russell B.; Ginzburg, Valeriy V.; Matsen, Mark W.; Balazs, Anna C. (American Chemical Society, 2002)
      Mixtures of diblock copolymers and nanoscopic spherical particles can yield well-ordered hybrid materials, which can be used for separation processes, catalysis, and optoelectronic applications. Predicting the morphologies ...
    • Effect of Nanoscopic Particles on the Mesophase Structure of Diblock Copolymers 

      Lee, Jae Youn; Thompson, Russell B.; Jasnow, David; Balazs, Anna C. (American Chemical Society, 2002)
      Introduction. The fabrication of novel biomimetic photonic and electronic materials requires the manipulation of both organic and inorganic materials at the nanometer length scale. One possible means of achieving this level ...
    • Entropically Driven Formation of Hierarchically Ordered Nanocomposites 

      Lee, Jae Youn; Thompson, Russell B.; Jasnow, David; Balazs, Anna C. (American Physical Society, 2002)

    • Origins of Elastic Properties in Ordered Block Copolymer/Nanoparticle Composites 

      Thompson, Russell B.; Rasmussen, Kim O.; Lookman, Turab (American Chemical Society, 2004)
      We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system. This weakening is due ...
