  • [2012-04-26] The InterMesh Network Architecture-Demo Proposal 

    Abdallah, Chaouki T.; Khoury, J.; Crichigno, J.; Jerez, H.; Shu, W.; Heileman, G.
    There is an indispensable need for inter-networking of WPAN-, WLAN-, WMAN- and cellular-based wireless mesh networks. Currently, the Internet protocol (IP) is employed to provide this functionality at the network layer. ...
  • [2012-04-26] Support Vector Machines for Direction of Arrival Estimation 

    Abdallah, Chaouki T.; Rohwer, Judd A.
    Machine learning research has largely been devoted to binary and multiclass problems relating to data mining, text categorization, and pattern/facial recognition. Recently, popular machine learning algorithms have successfully ...

    Abdallah, Chaouki T.; Perez-Gonzalez, F.
    In this paper we study the fragility of controllers designed to optimize some performance indices. We trace the fragility problem to the dimension of the resulting controllers, and use results from high-dimensional geometry ...
  • [2012-04-26] On the Relative Degree of Simultaneously Stabilizing Controllers 

    Abdallah, Chaouki T.; Bredemann, M.; Dorato, Peter
    In this brief paper 1 we present new necessary and sufficient conditions on the controller for the existence of a single controller to stabilize a set of n SISO plants: P1; P2; :::; Pn. As is well known this is equivalent ...
  • [2012-04-26] Performance of Game Theoretic Power Control Algorithms forWireless Data in Fast Flat Fading Channels 

    Abdallah, Chaouki T.; Hayajneh, M.
    We consider a game-theoretic power control algorithm for wireless data realistic channels. We study the performance of the algorithm for wireless data in the fast, flat-fading channel mobile users encounter in accessing ...

    Abdallah, Chaouki T.; Sandoval-Rodriguez, Rafael; Hokayem, Peter F.; Byrne, Raymond H.
    This work presents an Internet-Like Protocol (ILP) to coordinate the formation of n second-order agents in a two dimensional (2D) space. The trajectories are specified trough via points and a desired formation at each ...
  • [2012-04-26] An Overview of Quasi-Monte Carlo Methods in Control Systems 

    Abdallah, Chaouki T.; Hokayem, P.F.; Dorato, P.; Mastellone, S.
    Many control problems are so complex that analytic techniques fail to solve them [2]. Furthermore, even when analytic solutions are available, they may be computationally costly [2] and generally result in very high-order ...
  • [2012-04-26] Application of Statistical Learning Control to the Design of a Fixed-Order Controller for a Flexible Beam 

    Abdallah, Chaouki T.; Ariola, M.; Koltchinskii, V.
    This paper shows how probabilistic methods and statistical learning theory can provide approximate solutions to “difficult” control problems. The paper also introduces bootstrap learning methods to drastically reduce the ...
  • [2012-04-26] Finite-Time Control of Uncertain Linear Systems Using Statistical Learning Methods 

    Abdallah, Chaouki T.
    In this paper we show how some difficult linear algebra problems can be “approximately” solved using statistical learning methods. We illustrate our results by considering the state and output feedback, finite-time robust ...
  • [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 ...
  • [2012-04-24] Los Libertadores: Science and Technology Education in Latin America 

    Abdallah, Chaouki T.; Jordan, R.; Pollard, L. H.; Sanín, J.; Miskulin, M.; Franco, P.; De Giusti, M.
    The world has become dependent on information, technology, and telecommunications. Better known as Information Technology and Telecommunications (IT), a term that encompasses the fields of Electrical and Computer Engineering ...

    Abdallah, Chaouki T.; Lewis, F. L.; Maliotis, G.
    An adaptive controller is developed that takes advantage of the structure and any known dynamics of the system in order to increase speed of adaptation and relax the conditions required for convergence. The control design ...
