      Widmer, Christopher Daniel (2015-07)
      NAT traversal presents a challenge to Peer to Peer (P2P) applications, as in many instances a third party is needed to help initiate communication between two hosts when one is behind one or more NAT devices. Much work has ...
    • Natural gas to oxygenated gasoline 

      Boger, Craig; Collins, Reid; Romines, Corey; Worrell, Julia

      Several mesoscale data analysis systems are reviewed, of which one is then adapted and applied to the complex terrain of northwest Utah and the western United States. The analysis system relies on the simple, but computationally ...
    • Network traffic anomaly detection based on packet bytes 

      Mahoney, Matthew V. (2002-09-06)
      Hostile network traffic is often "different" from benign traffic in ways that can be distinguished without knowing the nature of the attack. We describe a two-stage anomaly detection system for identifying suspicious ...
    • Neural control of smart electromagnetic structures 

      Thursby, Michael H.; Yoo, Kisuck; Grossman, Barry G. (1991-12-01)
      Artificial neural networks (ANNs) and their ability to model and control dynamical systems for smart structures, including sensors, actuators, and plants, are directly applicable to the smart electromagnetic structures ...
    • Neural network approach to the determination of the geophysical model function of the ERS-1 C-band spaceborne radar scatterometer 

      Alhumaidi, Sami M.; Jones, W. Linwood (1997-04-04)
      Geophysical Model Functions (GMF) describing the relationship between the scatterometer normalized radar cross section (sigma-0) and useful geophysical parameters such as sea-surface wind vectors, wave heights, and sea- ...
    • Neural network architecture for solving the algebraic matrix Riccati equation 

      Ham, Fredric; Collins, Emmanuel G. (1996-03-22)
      This paper presents a neurocomputing approach for solving the algebraic matrix Riccati equation. This approach is able to utilize a good initial condition to reduce the computation time in comparison to standard methods ...
    • Neuro-glial and systemic mechanisms of pathological responses in rat models of primary blast overpressure compared to "composite" blast 

      Svetlov, S.I.; Prima, V.; Glushakova, O.; Svetlov, A.; Kirk, D.R.; Gutierrez, H.; Serebruany, V.L.; Curley, K.C.; Wang, K.K.W.; Hayes, R.L. (2012)
      A number of experimental models of blast brain injury have been implemented in rodents and larger animals. However, the variety of blast sources and the complexity of blast wave biophysics have made data on injury mechanisms ...
    • A Neurocomputing Approach for Monitoring Plinian Volcanic Eruptions Using Infrasound 

      Ham, Fredric; Iyengar, Ishwarya; Hambebo, Bereket Mathewos; Garcés, Milton A.; Deaton, John E.; Bellesiles, Anna; Williams, Brian (2012-10-03)
      Plinian volcanic eruptions can inject a substantial amount of volcanic ash and gas into the stratosphere, which can present a severe hazard to commercial air traffic. A hazardous volcanic ash eruption was reported on April ...
    • Neutral pion production with respect to centrality and reaction plane in Au+Au collisions at √sNN=200 GeV
