Abstract: In this paper, an artificial bee's colony (ABC) algorithm based neuro fuzzy controller (NFC) will be proposed for improving the performance of UPQC. Here, the error and change of error voltage of the system is to be applied to the neural network. The output of the neural network optimized by ABC algorithm and the network output is enhanced. By the optimized output, the optimal fuzzy rules are generated and the discharging capacitor voltage is calculated from the bias voltage generator. The proposed technique is implemented in MATLAB working platform and the performance is evaluated with voltage sag power quality problem. The power quality compensating performance of the proposed method is compared (ABC-NFC) with ANFIS, ANN, FLC and NFC. Then, the RMS voltage of proposed method is evaluated after solving PQ problem.

Keywords: UPQC, Neural Network, Fuzzy Logic controller and Power Quality Issue, Voltage Sag, ABC algorithm.

Abstract: This work is a comparison of different illuminants to find the optimal solution for different road lighting condition.The spectrum of different lamps are analysed phtotmetrically under spetroradiometer and datas are analysed keeping in mind the task of driving on road at night as base and thus approaching to an optimal solution.

Keywords : Optimal road lighting solution, spectrum analysis, task of driving, spetroradiometer.

Abstract: There are three primary ways for an aircraft to change its orientation relative to the passing air. Pitch (movement of the nose up or down, rotation around the transversal axis), Roll (rotation around the longitudinal axis, that is, the axis which runs along the length of the aircraft) and Yaw (movement of the nose to left or right, rotation about the vertical axis).
