Analysis of Error & Life Prediction of Corroded Metal Plate using NDT Technique
-Purnendra Srivas ; Devesh Shrivastava
This paper summarizes some of the major aspects of precision ultrasonic thickness gauging. Ultrasonic nondestructive testing (NDT) characterizing material thickness, integrity, or other physical properties by means of high-frequency sound waves has become a widely used technique for quality control. In thickness gauging, ultrasonic techniques permit quick and reliable measurement of thickness without requiring access to both sides of a part.
Corrosion is one of the serious problem affecting ship, pipe line and aviation industries. It affects the body of ship and thickness of pipe and an Aeroplane wings, surface, between joints and fasteners. The presences of corrosion underneath the paints of surface and between joints are not easy to be detected. The unnoticed presence of corrosion may cause many accidents leading to human and money loses. To detect the thickness of the metal surface, various methods and tests are used. These tests conducted should be such that it does not destroy or disassemble the equipment to parts or damage its surface Hence for the further use of the equipment, Non-destructive tests (NDT) are carried out. In the field of NDT industry one of the most important method to detect the thickness of component is the ultrasonic thickness measurement. The change in the thickness of any plate with respect to the time is also helpful for determining the corrosion rate and prediction of remaining life of corroded plate as well as prediction for the measurement error due to corrosion of any steel plate. Mild Steel is one of the major construction materials used in the industries. This thesis focuses on the experimental study of the corrosion behaviour and mechanism for mild steel in three different media namely: 0.1M of Hydrochloric acid, Atmosphere, Salt water (Nacl). Mild steel of length 12 cm and 10 cm width and 6 mm thick was used for this experiment and studied for a period of one year interval of each three month weighing and re-immersing. The weight losses were tabulated and analysed graphically. Any suitable NDE technique, such as ultrasonic may be used as long as it will provide minimum thickness determinations.

-D.Kamalasri ; J.Arun Prasath ; R.Thandaiah Prabu
Predictions of incoming solar energy are acquiring more importance, because of strong increment of solar power generation. Predictions is very useful in solar energy applications because it permits to generate solar data for locations where measurements are not available. In existing systems, solar radiation is predicted using fuzzy logic and neural networks separately. So that Mean absolute percentage error is greater than 10%. Fuzzy logic and neural networks are combined together using Takagi Sugeno Kang (TSK) method. TSK method is very efficient than mamdani method. Previous year solar radiation data is collected from National Environmental Agency and using this values neural network was trained. The graph between measured and predicted data values was plotted .Error is calculated using the difference between desired and output value. Prediction using combination of fuzzy and neural network model having Mean Absolute Percentage Error 6% was achieved. But in order to reduce Absolute Percentage Error value, we need to check the validity of the input data, so, that Adaboost algorithm is introduced in our proposed method. Adaboost algorithm is one of the best method of classification of weak learners. The algorithm classifies the training and testing data and also produces the corresponding errors. After finding the errors, it will be neglected from input data to make the predicted with more accuracy and less error. So that Mean Absolute Percentage Error -2.33% was achieved. Read More...

Multipath TCP: - Great Appeal For Telecommunications Providers
-Mamta kumari
Networks have become multipath: mobile devices have multiple radio interfaces, datacenters have redundant paths and multihoming is the norm for big server farms. Mean-while, TCP is still only single-path.Is it possible to extend TCP to enable it to support multiple paths for current applications on today’s Inter-net? The answer is positive. We carefully review the constraints—partly due to various types of middleboxes— that influenced the design of Multipath TCP and show how we handled them to achieve its deployability goals. We report our experience in implementing Multipath TCP in the Linux kernel and we evaluate its performance. Our measurements focus on the algorithms needed to ef-ficiently use paths with different characteristics, notably send and receive buffer tuning and segment reordering. We also compare the performance of our implementa-tion with regular TCP on web servers. Finally, we dis-cuss the lessons learned from designing MPTCP. Read More...

Energy Efficiency Routing in Wireless Sensor Networks using Child Sink Nodes
-Simple Preet Kaur Maan ; Dinesh Kumar
Wireless sensor network (WSN) consists of hundreds of sensor nodes organized in a particular order and deployed in geographical area to achieve presumed goal. Though WSNs have restrictions in terms of memory and processors, the main restraint that makes WSNs dissimilar from conventional networks is the battery trouble which limits the network lifetime. Transmission of data requires more energy as compared to sensing data. Distance between source and destination plays an important role in energy utilization. Sensor networks using the concept of mobile sinks is an optimum approach for maximizing the lifetime of WSN. Sink node aggregates the data from the common sensor nodes to conserve the battery of the different nodes. The data collected by sink node is then forwarded to the base station node. Read More...

-Varsha Shivaji Chaudhari ; Prof.Tarannum S.Shaikh
An Implementation of Fuzzy Classifier Systems is described in this paper. The classifier system is based on ability to improve performance for real time environment Open environment is full of pollution in the presence of the air. One can find the physical parameters of the pollution using fuzzy logic membership functions & fuzzy cardinality and relative fuzzy cardinality. We propose also an interface that makes easier to the user the task of writing, compiling and administering the rules stored in theKnowledgeBase. Fuzzy logic is a natural basis for modelling and solving problems involving imprecise knowledge and contin-uous systems. Unfortunately, fuzzy logic systems are invariably static (once created they do not change) and subjective (the creator imparts their beliefs on the system). In this paper we address the question of whether systems based on fuzzy logic can e ectively adapt themselves to dynamic situations. Read More...

ANN based Tuning of STATCOM in a Distributed Generation System
-M.Sudha ; M.Iyankalai; Dr.K.Punitha
In Recent trends integration of Distributed Generation (DG) units in the distribution system is one of the major concerns for electrical power system. The voltage control for small DG units in the grid is kept in the standard limit. There is lack in reactive power support that brings the problem of slow recovery and it leads to the usage of expensive Flexible AC Transmission System (FACTS) devices such as static synchronous compensator (STATCOM). STATCOM has been placed at the bus which requires reactive power control. Soft computing method of ANN’s is used for the prediction of voltage stability problems of the proposed systems. The training for the NN controller is done by using Back Propagation algorithm. It is obtained from MATLAB simulation results with the proposed ANN based tuning of STATCOM has effectively achieved the fast voltage recovery and power factor improvement. Read More...

Method to Prevent Caching Of JavaScript and CSS Files by ISP and At Browser End
-Bharti Ludhwani ; Ramesh Solanki; Neeraj Chawla
In modern times most of the application developed are web based. Development and maintenance process of these applications involves a lot of trials and errors at the frontend scripting side. Which is quite obvious, but many a times this development process is done on a client server environment. The problem that arises in this scenario is, most of the script files are cached by browser and Internet Service Provider (ISP). This is a feature provided by almost all browsers and many ISPs, to accelerate the load time of the pages and reduce the network load. However for developers this may turn out to be an irritating experience. As they keep on making changes to the scripts and sync with or upload it to the server. They are unable to see the changes because, of the caching of the script files by browser and ISP. Proposed system addresses this issue by applying a mechanism at the server side to break through this caching mechanism at both the level. Read More...

Scene Text Detection using Regression Tree Training
-Bhumi Patel ; Nneeta Chaudasama
Text detection and localization in natural scene images is important for content-based image analysis. This problem is challenging due to the complex background, the non-uniform illumination, the variant of text font, size and line orientation. In this paper, we present a hybrid approach to robustly detect and localize texts in natural scene images. A text region detector is designed to estimate the text existing confidence and scale information in image pyramid, which help segment candidate text components by local binarization. To efficiently filter out the non-text components, a conditional random field (CRF) model considering unary component properties and binary contextual component relationships with supervised parameter learning is proposed. Finally, text components are grouped into text lines/words with a learning-based energy minimization method. Since all the three stages are learning-based, there are very few parameters requiring manual tuning. Experimental results evaluated on the ICDAR2005 competition dataset show that our approach yields higher precision and recall performance compared with state-of-the-art methods. We also evaluated our approach on a multilingual image dataset with promising results. Read More...

-A.Priya ; Dr.K.Punitha ; S.Gunasekaran
In a deregulated environment, it may not always possible to deliver a contracted power due to the violation of system operating limits, it creates congestion in a transmission system. Flexible AC transmission systems (FACTS) devices can be an alternative to reduce the flows in heavily loaded lines resulting in an increased load ability, low system loss, improved stability and reduced cost of production. In this work, Multi objective congestion management is proposed. The objectives are to minimize the transmission losses, performance index, congestion cost and to maximize the voltage stability margin. Based on the real power performance index sensitivity method, the locations for the FACTS device are chosen. The voltage stability margin is increased using Voltage Stability Index (VSI). Genetic Algorithm (GA) gives a global optimal solution for a congestion management problem which is based on the nature of chromosomes. This has been performed on an IEEE 30 bus test system in MATLAB environment and the total congestion cost is evaluated by the genetic algorithm optimization technique. Finally, the congestion cost is compared by generator rescheduling method and the application of FACTS devices in the transmission line. Read More...

-Arulmurugan.S ; Prakash.S; Saravanan.K
Natural fiber composites are nowadays being used in various engineering applications to increase the strength and to optimise the weight and the cost of the product. Various natural fibres such as coir, sisal, jute, coir and banana are used as reinforcement materials. In this paper both treated and untreated banana fiber are taken for the development of the hybrid composite material. The untreated banana fiber is treated by sodium hydroxide to increase the wettability. The untreated banana fiber and sodium hydroxide treated banana fiber are used as reinforcing material for both Epoxy resin matrix and Vinyl ester resin matrix. Coconut shell powder is used along with both untreated and treated banana fiber as a reinforcing material. In this process the banana fiber is treated with 5% of sodium hydroxide for one hour and the specimen is fabricated by hand moulding process.

-Sneha Patel ; Narendra Limbad; Sazid Mahammad
A cloud computing is a fast growing area in computing research and industry today. It enables on- demand network access to a shared pool of configurable computing resources such as servers, storage and applications. Three main services provided by the cloud are Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). Private Cloud is restricted to a particular organization and data security risks are less compared to the public cloud. It is very difficult to execute multiple jobs on multiple systems rather than on single system simultaneously. Resource Scheduling refers to the set of policies to control the order of work to be performed by a computer system. It also manages availability of CPU time, processing time and good scheduling policy gives maximum utilization of resource. Round Robin , Equally Spread Current Execution and Throttled are existing algorithms. The objective of this paper is to propose efficient and enhanced scheduling algorithm that can maintain multiple VMs dynamically based on user requirement. Proposed algorithm is applied to optimize the throughput for processing of satellite images. Multiple Jobs are executed simultaneously considering system parameters like process time and CPU time in private cloud. Read More...
