Electroencephalography (EEG) measures electrical brain activity in a noninvasive manner. EEG mainly records electrical activity from radially oriented pyramidal cells in the cerebral cortex. However, EEG is less influenced by the tangentially oriented pyramidal cells. Magnetoencephalography (MEG) is influenced by the tangentially oriented pyramidal cells. However, MEG is not as widely available as EEG. Recent studies show that the combined used of EEG and MEG can improve the accuracy of source reconstruction, especially in neurological disorders (e.g. epilepsy). A current-based EEG system could allow us to record from the tangentially oriented pyramidal cells. The current work presents the development and validation of such a current-based EEG system. The system is adapted from a previously developed current-based electromyography (EMG) system. Characterization data and pilot EEG recordings in a human subject are presented. Further work will focus on miniaturizing the system to interface with the standard EEG cap, as well as developing a multichannel system.

In this paper a Wind Energy Conversion System based on Doubly Fed Induction Generator (DFIG) with series active compensator without additional transformer is proposed. The series compensator acts on the compensation of the grid voltages disturbance (harmonic distortion, voltage sag and voltage swell) in the DFIG stator voltages. The series active compensator is based on three H-bridge inverters operating with floating capacitors. The proposed control system regulates the floating capacitors voltages with no need for external sources. Simulation and experimental results are presented in order to evaluate the proposed system.

Visible light communications (VLC) are a novel technology that employs LEDs lamps to transfer data between devices, and has the potential to improve wireless communications in the following years. Relay-based cooperative communication, a technique developed for RF communication, takes advantages of spatial diversity without the need of additional resources on the communication transceivers. In this paper, we present a simulation model for the VLC channel with amplify-and-forward cooperative cooperation and show that it can improve the performance of such systems at indoor scenarios.
