  • [2012-03-30] Technology education challenges and solutions in Latin America 

    Abdallah, Chaouki T.; Jordan, R.; Pollard, H. L.; Sanín, J.; Van Reenen, J.; De Giusti, M.; Franco, P.
    The world has become dependent on information, technology, and telecommunications, better known as Information Technology and Telecommunications (IT&T), a term that encompasses the fields of Electrical and Computer ...
  • [2012-04-24] A temperature compensated L-band hybrid SAW oscillator and resonator filter 

    Abdallah, Chaouki T.; Ladd, J.; O’Shea, T.
    A 950 MHz subminiature temperature compensated SAW resonator oscillator (TCSO) and a SAW resonator filter are developed in hybrid form for application as local oscillator and bandpass filter f o r a communication system. ...
  • [2012-04-06] Time delay and power control in spread spectrum wireless networks 

    Abdallah, Chaouki T.; El-Osery, Aly; Jamshidi, Mo
    Delay in the computation of the signal-to-interference ratio in communication systems is unavoidable. In the case of mobile communication, delay is a very critical problem due the fast variation of the communication channel ...
  • [2012-04-12] Toward “smart tubes” using iterative learning control 

    Abdallah, Chaouki T.; Soualian, Vatche S.; Schamiloglu, Edl
    In the paper, we present our progress toward designing a “smart” high-peak power microwave (HPM) tube. We use iterative learning control (ILC) methodologies in order to control a repetitively pulsed high-power backward-wave ...
  • [2012-04-07] Tracking control of uncertain systems 

    Abdallah, Chaouki T.; Koltchinski, V.; Efromovich, S.; Heileman, G.L.
    Deals with the problem of designing output tracking controllers for uncertain systems. The systems we consider may be non-minimum phase but are restricted to be linear. The problem is motivated by control applications where ...
  • [2006-03-10] Two Design Techniques for Digital Phase Networks 

    Brophy, Francis; Salazar, Andres C.
  • [2012-04-12] A unification between nonlinear-nonquadratic optimal control and integrator backstepping 

    Abdallah, Chaouki T.; Haddad, Wassim M.; Fausz, Jerry L.; Chellaboina, Vijaya-Sekhar
    In this paper we develop an optimality-based framework for backstepping controllers. Specifically, using a nonlinear-nonquadratic optimal control framework we develop a family of globally stabilizing backstepping controllers ...
  • [2012-01-31] University Technology & Economic Development - The URC: A Proposed Model for Innovation and IP Capital Deployment 

    Salazar, Andres C.
    This paper describes an organizational model – the University Research Corporation (URC) - that would serve to expedite the development and deployment of technology in alignment with the mission of a college or university ...
  • [2012-03-29] The use of machine learning in smart antennas 

    Abdallah, Chaouki T.
    The goal here is to make arrays "smart" so that when one of the antenna elements in the array fails, the beamforming and beamsteering performance of the array degrades gracefully. Such an objective can be achieved in ...
  • [2012-03-30] WEB-based Enabling of Education and Research in ISTEC The ChipsnSalsa Portal 

    Abdallah, Chaouki T.; Jordan, Ramiro; Jerez, Henry; Van Reenen, Johann; Jacquenot, Guillermo; Vargas, Daniel
    WEB-based education tools that incorporate static content, video-on-demand, live synchronized video, as well as collaboration research spaces, often present information as isolated and diffuse topics compromising the ...
  • [2012-03-30] Wireless Camera and Site Survey Issues over an IEEE 802.11 b based wireless network test bed 

    Abdallah, Chaouki T.; Raghavan, Sunil; Jerez, Henry N.; Jordan, Ramiro
    Wireless LAN systems based on IEEE 802.11 have been a proved and sought after technological innovation, over the past few years. In this paper, we discuss some of the technical aspects for testing and deploying a wireless ...
  • [2012-03-23] Wireless Communications Networking: and An Overview 

    Abdallah, Chaouki T.; Jordan, Ramiro
    This paper presents an overview of wireless local-area networks (LANs) and wireless personal area networks (PANs), with emphasis on the two most popular standards: IEEE 802.1 1, and Bluetooth. While there are many such ...
  • [2012-04-26] Witsenhausen’s counterexample and its links with multimedia security problems 

    Abdallah, Chaouki T.; Comesana, Pedro; Perez-Gonzalez, Fernando
    Witsenhausen’s counterexample was proposed more than four decades ago in order to show that affine control strategies are not optimal for systems with non-classical information patterns. Finding the optimal solution to ...
