    A brain-computer interface (BCI) is a system that conveys messages and commands directly from the human brain to a computer. The BCI system described in this work is based on the P300 wave. The P300 is a positive peak of an event-related potential (ERP) that occurs 300 ms after a stimulus. One of the best-known and most widely used P300 applications is the P300 speller designed by Farwell-Donchin ... View full abstract»

    In this paper a new strategy for observing and analyzing a basketball match using video processing techniques to identify the game systems of a team is described. The system tracks players' positions during the match. At the outset, three video streams from three fixed cameras are available, each processed separately to deliver measures of the players' positions from different available views. Eac...

    Intuitively, many wireless and sensing applications benefit from knowledge of network boundaries. Many virtual coordinate constructions rely on the farthest set of nodes as beacons. Network edges may also bound routing holes in the network or regions of failure due to environmental effects, or they may indicate the need for additional deployment. Solutions that are both manageable and accurate rem... View full abstract»

    In this paper, a framework for applying reinforcement learning (RL) to the design and control of power system stabilizers (PSSs) is proposed. A near-optimal coordinated design for several PSSs is achieved using reinforcement learning. The objective of the control policy is to enhance the stability of a multi-machine power system by increasing the damping ratio of the least-damped modes. An RL meth... View full abstract»

  • Opportunistic spectral access through suppression of impulsive interference

    Cognitive radios are slated to be the next generation of smart transceivers that can opportunistically access spectrum through dynamic sensing of their immediate radio frequency (RF) environment. Such spectral sharing will be limited primarily by the interference that a cognitive user may potentially cause to the licensed primary user of the band. In particular, all cognitive transmitters located ... View full abstract»

    This paper describes the optimization, parallelization, and simulated execution performance of a software double-binary turbo decoder implementation supporting the WiMAX standard suitable for software-defined radio (SDR). Turbo codes offer excellent error-correcting performance, but they introduce significant computational demands in a communication system. In order to enhance execution performanc...

  • Near-linear wirelength estimation for FPGA placement

    With rapid advances in integrated circuit technology, wirelength has become one of the most critical and important metrics in all phases of VLSI physical design automation, especially circuit placement. As the precise wirelength for a given placement can only be known after routing, accurate and fast-to-compute wirelength estimates are required by FPGA placement algorithms. In this paper, a new mo... View full abstract»
