In this paper we investigate comparative analysis of different antenna parameter (directivity, side lobe level and convergence time ) by using different type of optimizing technique such as Taguchi‟s, PSO, RCGA for synthesis of broad side and end fire linear antenna array in WI-MAX application. On ampere current is provided to each element and radiated power is decreases and radiation intensity...

This paper presents estimation of d-axis and q-axis inductance of an interior permanent magnet synchronous motor (IPMSM) by using an extended Kalman filter (EKF). The EKF is widely used for control applications including the motor sensorless control and parameter estimation. The motor parameters can be changed by temperature and air-gap flux. In particular, the variation of the inductance affec...

This paper proposes a low voltage CMOS nano-ampere current reference circuit and presents its performance with circuit simulations in 180-nm technology. The proposed circuit consists of biasvoltage, current-source and offset-voltage sub-circuits with most of MOSFETs operating in subthreshold region. Simulation results show that the circuit generates a stable reference current of 110-nA in suppl...

The properties produced by integral coloured anodic oxide films and sulphuric acid, oxalic acid, maleic acid and different anodizing aluminium alloys -Si, Mg, Fe, Cuare studied. A two stage anodizing procedure was employed. The influence of alloy and solution composition, temperature, concentration, voltage, ampere, time from optimization simplex and anodizing conditions are considered. An oxid...

In this paper we further develop the theory of f-divergences for log-concave functions and their related inequalities. We establish Pinsker inequalities new affine invariant entropy obtain on functional surface area lower upper bounds Kullback-Leibler divergence in terms area. The lead to L_p-affine areas convex bodies.
