      Several models were used to describe the partitioning of ammonia, water, and organic compounds between the gas and particle phases for conditions in the southeastern US during summer 2013. Existing equilibrium models and ...
    • Coverage Analysis Methods for Formal Software Testing 

      Lee, John A. N.; He, Xudong (Department of Computer Science, Virginia Polytechnic Institute & State University, 1987), TR-87-04
      Software creation requires not only testing during the development cycle by the development staff, but also independent validation following the completion of the implementation. However in the latter case, the amount of ...
    • Covering a Set with Arithmetic Progressions is NP-Complete 

      Heath, Lenwood S. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1989), TR-89-25
      This paper defines a new class of set covering problems in which the subsets are implicitly derived from the properties of the set elements. In particular, the set elements are integers and the subsets are finite arithmetic ...
    • CP-Rays in Simplicial Cones 

      Kelly, Leroy M.; Murty, Katta G.; Watson, Layne T. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1987), TR-87-25
      In classical mathematics, interest in the concept of regularity of a triangle, is mainly centered on the property that for every interior point of the triangle, its orthogonal projection on the line containing each side ...
    • CPU MISER: A Performance-Directed Run-Time System for Power Aware Cluster 

      Ge, Rong; Feng, Xizhou; Feng, Wu-chun; Cameron, Kirk W. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2007), TR-07-14
      Performance and power are two primary design constraints in today’s high-end computing systems. Because of the inherent dependency between performance and power, reducing power consumption without impacting system performance ...
