    Abdallah, Chaouki T.; Cortez, R.A.; Tanner, H.G.; Lumia, R.
    We develop a control scheme for a group of mobile sensors to map radiation over a given planar polygonal region. The advantage of this methodology is that it provides quick situational awareness regarding radiation levels, ...
  • [2010-06-25] Information theoretic approach for assessing image fidelity in photon-counting imagers 

    Srikanth, Narravula R., 08-15-1986
    The method of photon-counting integral imaging has been introduced recently for three-dimensional object sensing, visualization, recognition and classification of scenes under photon-starved conditions. In this work we ...
  • [2012-03-29] Inherent issues in networked control systems: A survey 

    Abdallah, Chaouki T.; Hokayem, Peter E.
    Due to major advancements in the area of networking over the past decade, a new paradigm of control systems has emerged, namely networked control systems. Such systems differ from classical control systems in that their ...
  • [2008-02-07] Injection locking characteristics of indium arsenide quantum dash lasers 

    Moscho, Aaron
    The study of injection locking characteristics was performed on an InAs Quantum Dash (QDash) semiconductor laser for the first time. The linewidth enhancement factor(α-parameter) of a QDash laser was measured using an ...
  • [2012-01-31] Innovation and National Economic Strategy 

    Salazar, Andres C.
    In the formulation of a national economic policy today the need to compete in a global knowledge economy has been recognized. The importance of the knowledge services sector now rivals that of materials and products and ...
  • [2012-01-31] Innovation and US Engineering School Ranking 

    Salazar, Andres C.
    An association between the national ranking of a graduate school in engineering and innovation is investigated by product moment analysis and Spearman correlation coefficients. This paper combines school statistical data ...
