One of the main components to form a major part is the reactive power in the system. It is required to maintain the voltage to deliver the active power through the lines. Loads like motor loads and other loads require reactive power for their operation. To improve the performance of ac power systems, we need to manage this reactive power in an efficient way and this is known as reactive power compensation. Reactive power can be best described as the quantity of “unused†power that is developed by reactive components, such as inductors or capacitors in the AC circuit or system. In a DC circuit, the product of “volt-amps†gives the power consumed in watts by the circuit. However, while this formula is also true for purely resistive AC circuits, the situation is slightly more complex in a AC circuit containing reactive components as this “volt-amps†product can change with frequency. There are two aspects to the problem of reactive power compensation: load compensation and voltage support. Load compensation consists of improvement in power factor, balancing of real power drawn from the supply, better voltage regulation, etc. of large fluctuating loads. Voltage support consists of reduction of voltage fluctuation at a given terminal of the transmission line. Two types of compensation can be used: series and shunt compensation. These quite satisfactorily do the job of absorbing or generating reactive power with a faster time response and come under Flexible AC Transmission Systems (FACTS).

However, lagoon water pollution has become a growing menace to human society and natural ecosystems in recent decades. Hence, it is vital to understand the spatial and temporal variability of pollutants within aquatic systems. Therefore, this study aimed to investigate the spatial and temporal variations of surface water of Batticaloa lagoon. This study was carried out from November, 2013 to June, 2014. Batticaloa lagoon was divided into three divisions based on anthropogenic activities where twenty sampling points were randomly selected from these divisions and water samples were taken monthly. Physico-chemical parameters such as temperature, pH, EC and TDS were measured at sampling points while TSS, TS, DO, BOD, phosphate, nitrate and turbidity were measured at laboratory. Data were analyzed statistically to interpret the results. Results showed that all the quality parameters tested except turbidity exceed the standard levels for aquatic life while DO falls within the acceptable range. There were high range in tested parameters, temperature ranged between 27.2˚C to 32.5˚C, pH 6.4 - 9.2, EC 600µS/cm - 1700μS/cm, TDS 296mg/l - 873mg/l, TSS 13mg/l – 35mg/l, phosphate 0.19mg/l - 0.76mg/l, nitrate 0.97mg/l - 2.60mg/l, DO 4.64mg/l - 7.12mg/l, BOD5 4.13mg/l - 8.66mg/l and turbidity 6.6NTU - 13.9NTU. Phosphate and nitrate levels significantly (p<0.05) varied among the divisions. Further, temperature, pH, EC, TDS, TS, DO and phosphate were high during dry season while TSS, BOD, nitrate and turbidity were high during wet season. The variations of EC, TDS, TS, TSS, BOD and turbidity between wet and dry seasons were also significant. The study concludes that, the Batticaloa lagoon water has been polluted. However, pollution level is not severe. Therefore, measures should be taken to prevent the further pollution of Batticaloa lagoon.

The main objective of the proposed system to identify the community in the multidimensional data such as users , Tags , stories , locations ,employment details ,photos and comments . We propose a data mining technique to detect the frequently interacting users based on the common subjects and grouping them in single community. The main incorporation of the work is to identify a seed-based community in a multi-dimensional network by evaluating the affinity between two items in the same type of entity (same dimension) or different types of entities (different dimensions) from the network. Our idea is to calculate the probabilities of visiting each item in each dimension, and compare their values to generate communities from a set of seed items and explore the feature evolution from the seed item in the same dimension or different dimension.

In MANETs many routing protocol works as on-demand routing protocol and these on-demand protocols have faster response time and lower overhead. In MANET there are many attacks that affect the routing and one of them is rushing attack. In this paper, we have study various prevention techniques, which are used to prevent the rushing attack. In Rushing attack, a malicious node or an attacker further the speed of routing process. Rushing attacks represent one of such possibilities. In these Rushing attacks, malicious nodes send the Route Request (RREQ) packets, asking for a route, to the destination node quicker than the legitimate nodes do.

Some error bit and noise is added with data when the data is transfer through communication network. Error Correction Codes are used to generate the original data at the receiver side by removing error and noise. Communication performance is improved by enabling the transmitted signal to better withstand the effects of channel disabilities such as noise, interference and fading which occur during transmission as well as during comparison. In short the Error Correction is the detection of errors and reconstruction of the original, error free data. There are errors correcting codes to detect as well as correct errors. One of the main drawback of error correcting code is time of the execution which increase the delay in the communication network. In this paper error correction code is implemented with the pipelining technique to improve the execution time of the communication system.

Large scale of biometric systems are used both in commercial and government agencies to increase the level of security. Face recognition is the powerful method of recognizing an individual. It is a computer application which compares the facial features with the database image. A unique approach is introduced for recognizing multi pose images with different conditions. The classification is performed by using Back Propagation Algorithm and Radial Basis Algorithm and Adaptive Neuro Fuzzy Inference System. The proposed method is based on extraction and Eigen face method. Experimental results are tested using FERET database and shows that the proposed method is effective for face recognition. The feature extraction using PCA is to reduce the dimensionality and to calculate the feature points. The performance evaluations between the proposed methods are analyzed. The characteristic features calculated using PCA called Eigen faces are obtained from the stored images are combined with the Back Propagation Neural Network, Radial Basis Function Network and Adaptive Neuro Fuzzy Inference System algorithms for recognition of images. For extracting the feature points from the input image, entropy and mean of each image are detected. The experimental results on performance of testing images are compared with Back Propagation, Radial Basis Function Network and Adaptive Neuro Fuzzy Inference System algorithms. Thus Face recognition can be achieved through the architectures and algorithms of artificial neural networks.

First it was believed that minutiae set is not sufficient for reconstruction of fingerprint image. But, in this paper with the help of prior knowledge termed as orientation patch dictionary and continuous phase patch dictionary it is somehow possible to reconstruct fingerprint image from their minutiae representations. The two dictionaries improves the reconstruction of fingerprint. Orientation patch dictionary helps in reconstruction of orientation field, and continuous phase patch dictionary helps in reconstructing ridge patterns.

In the present scenario there is a increasing demand of high speed internet which require more capacity and more bandwidth. The effect of chromatic dispersion can be reduced by compensation technique. [1, 2] The chromatic dispersion also has inverse relationship with FWM. In this paper we used post dispersion compensation along with the fiber Bragg grating to reduce the effect of chromatic dispersion. Also we can compare the Bit error rate at different power levels 5 db, 10 db and 20 db while the length of fiber is fixed. After simulation it is proven that bit error rate is a function of input power level. The pulse broadening is a function of length of fiber which has been shown in this work When the BER increases quality factor decreases and overall fiber optic system degraded. In this paper we also prove that the BER is also a function of Length of Fiber. As the fiber length increases BER also increases. The whole simulationn is performed by Optisystem simulation software. Also by examine the eye diagram it is clear that link performance is improved by using dispersion compensation.
