This paper presents the modeling of a four rotor vertical takeoff and landing (VTOL) unmanned air vehicle known as the quad rotor aircraft. The paper presents a new model design method for the flight control of an autonomous quad rotor. The paper describes the controller architecture for the quad rotor as well. The dynamic model of the quad-rotor, which is(More)

This paper describes the development of a synchronous, online brain computer interface (BCI) system based on detecting the steady-state visual evoked potential (SSVEP). The system includes a programmable visual stimulator, EEG amplifier with filter system, data acquisition card, and signal processing and classification algorithms. Two types of experiments(More)
This paper proposes the architecture of a ubiquitous healthcare system for hospitals and care institutions which is based on application of wireless sensor networks. This system aims to obtain vital signals like ECG and body temperature from multiple patients and transmit it through wireless network to the network coordinator node which is under direct(More)
This paper details a new coordinated design between power system stabilizers (PSSs) and a unified power flow controller (UPFC) using genetic algorithms (GAs). A GA scheme determines the optimal location for a UPFC while tuning its control parameters, resulting in the optimization of the quantity, parameters, and locations of PSSs under different operating(More)
Hyper-redundant manipulators have large number of kinematic degrees of freedom, thus processing some unconventional features such as the ability to enter a narrow space while avoiding obstacles. To solve the problem of multi-solution caused by redundancy, a geometrical method is presented in this paper. This proposed method finds one optimal solution to the(More)
The EEG signal is most useful for clinical diagnosis and in biomedical research. ElectroOculoGram (EOG), ElectroMyoGram (EMG) artifact are produced by eye movement and facial muscle movement respectively. An adaptive filtering method is proposed to remove these artifacts signals from EEG signals. Proposed method uses horizontal EOG (HEOG), vertical EOG(More)
