Numerical Analysis of Aerofoil Section of Blade Of axial Flow Fan at Different Angle Of Attack
Fans are used all over the world in a wide verity of industries and other purposes. Some of the important applications are in steam power station, ventilation system, cooling of electric motor and generator, and many industrial processes. Many researchers and engineers are making their efforts to design fans to fulfill the particular requirement of application in the most efficient way. The criterion of cost of fan, ease in manufacture and conservation of energy are other also to be considered in design. Several studies are available of various researchers in analysis and simulation of axial and centrifugal fans. Axial flow fans have also been designed and simulated by the researchers. Simulation of performance of axial flow fans and design of various blade sections of the axial flow fans have been studied experimentally or numerically. The present work comprises the numerical study of the axial flow fan section aerofoil. The objective of the study is to simulate the flow features around the aerofoil of particular design for three different values of the striking angle. The results are obtained using FLUENT in the form of velocity vectors at the leading edge, across the aerofoil and at the trailing edge. The contours of pressure and turbulence are also shown for the three cases.

Image Fusion based on Integration of Wavelet and Curvelet Fusion Methods
In today’s period, there is a great impact of image registration and image fusion on many fields such civilian and defense areas to retrieve exact information about the particular image. the process in which different images of the same scene are captured as input images and those are combined in order to improvise the fused image content which gives more information and is complete than any of the input images. Different methods of image fusion technique are principal component analysis (PCA), Discrete Wavelet transforms (DWT), curvelet transform. Principal component analysis (PCA) is a spatial domain fusion technique, which deals with image pixels to reduce multidimensional data sets to lower dimensions for analysis. Discrete Wavelet transforms (DWT) and curvelet transform is the transform domain methods to integrate the input images and extract the exact required information. Discrete wavelet transform(DWT) has an impressive reputation as a tool for image processing in image denoising and image fusion application.The Curve lets transform is suited for objects which are smooth away from discontinuities cross curves. The application of the curvelet transform in image fusion would result in better fusion results than that obtained using Principal Component Analysis (PCA) and Discrete wavelet transforms (DWT) The idea behind the current research is to exhibit the enhancement in image processing parameters by implementing fusion of curvelet and wavelet using simple average and weighted average fusion method .

Present Position of Agriculture in India
Agriculture is facing problem due to monsoon and government has taken certain initiatives to encourage and protect agriculture. The stark observation made in the Economic Survey of 2015-16 that “Indian agriculture, is in a way, a victim of its own past success – especially the green revolution”, shows the dark reality of the agriculture sector at present and the havoc that has been wreaked by the green revolution. The green revolution, which is often characterized by the introduction of a high-yielding variety of seeds and fertilizers, undoubtedly increased the productivity of land considerably. But the growth in the productivity has been stagnant in recent years, resulting in a significant decline in the income of farmers. There have also been negative environmental effects in the form of depleting water table, emission of greenhouse gasses, and the contamination of surface and ground water. Needless to say, the agriculture sector is in a state of distress, which is severely affecting peasants and marginal farmers, and urgent policy interventions are required to protect their interests. The government has responded to the problem by constituting a panel, which will recommend ways to double the income of farmers by 2022. While this may be an overly ambitious target, if we want to boost stagnated agricultural growth a shift has to be made, as finance minister Arun Jaitley said in parliament, from food security of the nation to income security of the farmers. However, there are many hurdles that have to be crossed if we want to achieve this objective.

Does Location Difference Determines Political Awareness
The present study aims at investigating how far the college students are politically aware as a future citizens and whether there exist any difference among them with regard to location. The sample consists of 1611 college students studying at various colleges of arts and science in Tamilnadu. Descriptive method using survey as technique was employed to solve the present problem. Political Awareness Test (PAT) developed and validated by V.Sasikala and S.Francisca (2016) had been used for collecting the data. The data was analyzed using mean, S.D, ANOVA and scheffe. The result showed that majority of the college students are politically aware and location difference plays a dominant role determining political awareness.

Power Quality Improvement of Three Phase System Using Shunt Active Power Filter
Abstract— A power quality issue basically deals with any occurrence manifested in current, voltage or frequency deviation that results in damage, upset or failure of end use equipment. The non-linearity in the properties of power electronics devices and the higher switching frequency are the main causes of power quality issue. Thus this paper deals with power quality improvement by shunt active power filter to eliminate voltage and load current harmonics and for reactive power compensation. A shunt active power filter based on the instantaneous active and reactive current component (Id – Iq) method is proposed to compensate first harmonic unbalance. A theoretical study based on synchronous detection method is done in this paper and the simulation results are analyzed regarding the harmonics compensation. Simulations are carried out with PI controller for the (Id – Iq) control strategies for different voltage condition using MATLAB/ SIMULINK.
