    • Analysis of Energy and Soft Dirt in an Urban Untreated Sewage Source Heat Pump System 
      Qian, J.; Sun, D.; Li, X. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      When using urban untreated sewage as a cool and heat source of heat pump, it is unavoidable to form soft dirt. Based on the method of exergy, an analysis is given of the impact the dirt growth of a tube-shell sewage heat ...
    • Application Prospect Analysis of the Surface Water Source Heat-Pump in China 
      Zhang, C.; Zhuang, Z.; Huang, L.; Li, X.; Li, G.; Sun, D. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      Surface water resources in China are rather abundant and it can be use as the heat or cool source for heat pump. The winter surface water temperatures of 17 typical cities are investigated in December, and they are all ...
    • Bottomonium production at root s(NN)=200 GeV and root s(NN)=5.5 TeV 
      Grandchamp, L.; Lumpkins, S.; Sun, D.; van Hees, H.; Rapp, Ralf. (American Physical Society, 2006)
      Properties of bottomonia (Upsilon,chi(b), and Upsilon ') in the quark-gluon plasma (QGP) are investigated by assessing inelastic reaction rates and their interplay with open-bottom states (b quarks or B mesons) and color ...
    • Development of Energy Consumption Database Management System of Existing Large Public Buildings 
      Li, Y.; Zhang, J.; Sun, D. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)

    • Discussions on Disposal Forms of Auxiliary Heat Source in Surface Water Heat Pump System 
      Qian, J.; Sun, D.; Li, X.; Li, G. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      This paper presents two common forms of auxiliary heat source in surface water heat pump system and puts forward the idea that the disposal forms affect operation cost. It deduces operation cost per hour of the two forms. ...
    • Fast quantum noise in the Landau-Zener transition 
      Pokrovsky, Valery L.; Sun, D. (American Physical Society, 2007)
      We show by direct calculation starting from a microscopic model that the two-state system with time-dependent energy levels in the presence of fast quantum noise obeys the master equation. The solution of master equation ...
    • An Operational Energy Consumption Evaluation Index System for Large Public Buildings 
      Li, Y.; Zhang, J.; Sun, D. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      Large public buildings have been the emphasis of energy conservation in China. In this paper, the design and operational energy consumption evaluation indices for large public buildings are generalized, their differences ...
    • Optimization of the Fin Heat Pipe for Ventilating and Air Conditioning with a Genetic Algorithm 
      Qian, J.; Sun, D.; Li, G. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
