 Abstract

The long distance communication system in a cellular network for higher bit rate can be designed using the various dispersion compensator like DCF , FBG and ECF as well as hybrid techniques. We have compared different Q-factors for the SMF of 50 km and 100 km with or without using fiber bragg grating as dispersion comparator . In this paper the system performance is analyzed on the basis of Q-factor , Eye diagram at different length with and without compensator . Data transmission for high speed data transmission requires more bandwidth requirement , which is an important factor for the communication system . In DWDM system , each laser must emit light at a different wavelength , with all the lasers light multiplexed together onto a single optical fiber. After being transmitted through a high-bandwidth optical fiber , the combined optical signals must be de-multiplexed at the receiving end by distributing the total optical power to each output port and then requiring that each receiver selectively recover only one wavelength by using a tunable optical filter . In this paper , by using FBG the four wave mixing effect is reduced at different value of Q-factor .

 Abstract

Sentiment analysis is the process of defining opinion of the individual by extracting the data. Sentiment analysis is done by collecting the data from variety of resources like internet and social media platforms(Facebook, Twitter) and it is stored in different formats. The data extracted from these social media platforms can be used for different purposes like prediction, marketing and sentiment analysis. Politicians use sentiment analysis to know how people feel about themselves and their parties. Twitter is a widely used platform for posting comments through short messages. Every year millions or billions of tweets extracted are subjected to sentiment analysis. But handling such a huge amount of unstructured or structured data is a tedious task to take by the traditional storage system (such as RDBMS, Relational Database System). Therefore, we need a that can process and analyze this unrelated data. So, we have utilized big data technology to handle different formats of unstructured and structured data from different sources.

 Abstract

During the past, construction on soft subsoil was considered unsuitable, but nowadays it has become a necessity to do so since the availability of land for construction is decreasing at a rapid rate. Soil reinforcement is an effective and reliable technique for improving the strength and stability of soil. It also reduces the cost of stabilisation. The reinforcement of these soft sub soils with granular fill layers is one of the major soil improvement techniques. Soft soil behaviour can be improved by totally or partially replacing it with layers of compacted granular fill. The plate load tests were done to investigate the settlement of footing over the weak soil which was partially replaced using the replacement soil (granular pad) and reinforced with geogrid. Different tests were conducted for varying depths of the granular pads and also by varying the number of geogrid layers. It is now a common practice to use a layer of a geotextile or geogrid at the base of the fill layer, to separate the fill from soft soil beneath and to improve its load carrying capacity by the structural action of geotextile or geogrid.

 Abstract

The steganography is a specialty of concealing the presence of the information in another transmission medium to accomplish the confidential communication. It is not the substitute for the cryptography yet rather it helps the security. Steganography strategy utilized as a part of this system depends on reversible surface texture synthesis process. In the average steganography process people on two sides endeavour to make secure communication and whose achievement relies upon recognizing the presence of the communication. Existing steganography process is not efficient in terms of cost and size. Increase in the size of a message may lead to distortion of the image. A novel surface texture synthesis process enables to embed and conceal large size secret messages in the stego image. With the surface texture synthesis process the clear image is built from an input image and the image is split into the number of various patches. These patches are given a fixed ID and pasted randomly on the clear image. This provides high efficiency for embedding secure data, as the size of the cover image is dependent on the size of the secret message, which will allow storing large size information or message. This system can embed the large size secret message in the image and provide the high quality image which avoids the distortion of image quality.

 Abstract

In this approach, the selection of carrying free operation takes place in modulo residue converters. The residues are used to calculate the results of given arithmetic functions. An arithmetic unit is a special unit used to calculate any type of calculation in VLSI circuits. In modern technology, the size of VLSI chip is decreased for every one-and-half years. The performance of VLSI increases in terms of the area, and power consumption. The existing design contains reverse residue converters using prefix operator used to reduce delay requirements, the drawbacks in this design is power consumption increases and area increases due to its critical path. This project deals with residue converters by further enhancement a self-selection of modified carry is used. The implementation can take place using FPGA to reduce area and power concerns.

 Abstract

In this research paper, we address the Sybil attack in MANET. Most often the traditional measures against Sybil attack are not applicable in a MANET due to the differences in aims and architectures. The nodes in MANETs are mobile and limited in resources such as battery, bandwidth etc. Due to frequently changing topology it becomes expensive and impractical to authenticate communication and keep track of devices with a centralized server in such network. We proposed a framework which uses nodes attributes in order to judge their behavior. As Sybil nodes consumes data packet by providing wrong routing information repeatedly, we focus on the distinction of the node parameter value of Sybil node and legitimate node. This distinction is made on the basis of nodes attributes and by assigning fuzzy membership values to each node. For this we use fuzzy inference rule and Bezier curve as a tool. Here suspect any node means is to identify those nodes also whose behavior lie in between legitimate and Sybil nodes. In contrast to the traditional crisp logic in which a node can be either Sybil or legitimate fuzzy inference based model focus on the possibility of a node being Sybil. Later we verify their RSP values by drawing a Bezier curve at two different instant of time to identify the Sybil character.
