Generation of Patterns of E-Plane Horn Antenna Using Tapered Amplitude Distribution
Abstract: In this paper, analysis is made to generating directional patterns on E-plane sectoral horn antenna for radar applications. In literature survey, the work on E-plane sectoral horn antenna is inadequate. For radar applications need low EMI (Electro Magnetic Interference) to enhance this we attempted work on horn antennas and achieved low interference. To the implementation of horn antenna we used tapered amplitude distribution method to reduce the EMI.

Synthesis of Linear Arrays to Generate Difference Patterns for Radar Tracking Applications
Abstract: In this paper, we have proposed a non-uniform amplitude distribution method to generate difference patterns with low side lobe level of linear arrays for tracking applications. In the literature, most of the work has been attempted on the sum patterns. But, in the radar tracking applications difference patterns has been played very important role. In view of that, intensive investigations are carried out to produce difference patterns with low sidelobes. …

Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …

Indoor Room Air Conditioning Using External Enclosure
Abstract: This paper presents a new air conditioning system using an external air chamber enclosure. The system is based on evaporative refrigeration technique humidifying hot air from the environment by means of a new design humidifier. Temperature at the air chamber is set up according to the required comfort conditions. The air chamber plays the role of a heat collector from indoor room radiative energy. This new system avoids thermal gradient …

Dust Acoustic Solitary Waves in a Five Component Plasma-Application to Comets
Abstract: We have studied the characteristics of the Dust Acoustic Solitary Wave (DASW) in a five component cometary plasma composed of two components of electrons (one hotter and one colder), hydrogen ions and a pair of oppositely charged dust particles (heavier ions). The Korteweg – deVries wave equation has been derived for the system and its solitary wave solution obtained. The dust acoustic solitary wave amplitude is almost a constant with …

Application of Radial Basis Function Neural Network in Power Quality Events Classification
Abstract: Power Quality concerns have become more important as the Smart Grid has evolved. Computers, microprocessor-controlled electronic loads, and power electronic devices are all used in urban development. Disturbances in power quality are caused by these electronic devices. Variations in the amplitude and frequency of system voltages and currents from their nominal levels identify PQ difficulties. We offer a hybrid technique to accomplishing this goal in this paper. To classify PQ …

FLEXURAL VIBRATION OF NON-UNIFORM BEAM ON BI-PARAMETRIC FOUNDATION UNDER HARMONIC MOVING LOAD WITH NON-CLASSICAL BOUNDARY CONDITIONS
Abstract: The dynamic response to harmonically varying moving loads of non-uniform elastic beam resting on bi-parametric foundation with non-classical boundary condition, time dependent in particular is examined in this paper. Here, the beam is considered non-uniform, with the moment of inertia and the distributed mass varying continuously along the span L as functions of the position 𝑥. In order to guarantee a more stable structure and a reduce risk of resonance, …

Measurements and Analysis of Electric Power Quality
Abstract: The ideal supply voltage is pure sinusoidal voltage with nominal frequency and nominal amplitude.Any variation from this is considered as a power quality event or a disturbance. One importantaspect in the field of power quality is monitoring and control of the qualitative parameters of theelectrical energy according to today’s standards. In that way, a big attention is paid to define thedisturbances and determination of procedures for their measurement. A large …

Stress Perception among School-age Children
Abstract: Introduction: Prosody is the inflection embedded in speech. The perception of prosody is necessary to understand a spoken utterance, especially to appreciate the intricacies of languages. The influence of prosody is also beyond the boundaries of a sentence and provides speech its emotional tone. Prosody or the supra-segmental is made of stress (accent), intonation (pitch patterns) and the rhythmic (timing) pattern of language. Acoustically, it is described in terms of …
