 Abstract

A circuit breaker is an electrical switch which is invented to protect an electrical circuit from destructions due to overload or short circuit. Circuit breakers are used in AC and DC systems but compared to AC system interruption of dc fault current in DC system is more unreliable due to the absence of natural zero crossing. A solid state DC breaker in a DC system offers rapid response to faults, but it has greater power losses. The Z-source breaker is a type of solid state circuit breaker which was used conventionally in the systems. Nowadays researchers found that the Z-source circuit breaker topology along with the transformer coupling will allow us to detect fault and isolate the circuit suddenly. The proposed system consists of a thyristor based transformer coupling circuit for quick desolation purposes.

 Abstract

In this research work a sequence in timing of the traffic signals are used which are closer distance to each other so that we can move easily and vehicles does not get red signals. Advantages of sequence wise traffic signals is Low traffic, saving of time, saving of fuel, reduces probability of accidents, avoid heavy traffic. To have a proper sequenced system of traffic signals, here all the signal system arrange in a proper way so that each vehicle get green signal at every signal i.e. possibility of getting red signal is rare. Hence this sequencing minimizes the traffic jam at the signal.

Abstract: The need of strength and durability of products or materials used in concrete is more considerable on the aspects of low cost in concrete applications. This project deals with the experimental analysis on strength and durability of concrete by partially exchanging fine aggregate with oyster shell which is an illegitimately disposed waste from oyster farm places. To pursue for a chance to recover the waste as building ingredients, crushed oyster-shell were partially substituted for fine aggregate. To estimate the real-world application of crushed oyster shells as building constituents, the effort has been made to analysis the compressive strength of oyster shell concrete.

 Abstract

The issue of unintentional islanding in pv grid interconnection still remains as a challenge in grid connected pv system. Anti-islanding methods generally can be classified into four major groups, which include passive methods, active methods, hybrid methods and communication based methods. This study conclude that the setup and operation cost is the vital factor for anti-islanding method selection in order to achieve minimal compromising between cost and system quality. It is difficult to pinpoint generic methods for a specific application.

 Abstract

As we all know in space dimension we have distance ,speed and time. According to einstein general theory of relativity space and time are related to each other. But einstein theory also say that time and space are depending on each other. instead of assuming time as quantity we take it as dimension . according to Hilbert space we have n dimensional space means it have x1,x2,x3......xn co ordinate. similarly we can have time dimension which have co ordinate t1 , t2, t3. tn. a well proved fact projection of 3 dimension can be taken in two dinensions(space.). similarly we are living in projection time. our time is projection 6th dimension time co ordinate. so time and space dimension can be independent of each other under following conditions. *** if velocity of space is very high. we live in time dimension. as time is constant *** if velocity of time is high we live in space dimension which is what we are living. so from above time dimension is inversely proportional to time dimensions. T,=1/S or D=exp(T)

 Abstract

Internet has become a useful part of our regular day to day life as we do almost all of our social and financial activities online. Today, everyone is heavily reliable on internet and online activities such as online shopping, online Banking, online booking, online recharge and many more. Phishing is a type of social engineering attack that targets a user sensitive information through a phony website that appears similar to a legitimate site, or by sending a phishing email .Heuristic based approach is to produce a solution in a reasonable time that is good enough for solving the problem .Heuristic approach defines that it may produce results by themselves, or they may be used in conjunction with optimization algorithms to improve their efficiency (e.g., they may be used to generate good seed values). With the limitation in the existing system we are introducing additional features through the heuristic approach which is simpler and effective than the earlier approaches. This is mainly used for real-world applications and one of this is used in fraud detection on an online platform. Internet environment and diversification of available web services, web attacks have increased in quantity and advanced in quality. Heuristics approach through machine learning underlie the whole field of Artificial Intelligence and the computer simulation of thinking, as they may be used in situations where there are no known algorithm. The heuristic-based detection technique analyses and extracts phishing site features and detects phishing sites using that information. It is imperative to detect and act on such threats in a timely manner. However, blacklists cannot be exhaustive, and lack the ability to detect newly generated malicious URLs. To improve the generality of malicious URL detectors, machine learning techniques have been explored with increasing attention in recent years.

 Abstract

This paper presents the design and fabrication of combined pipe bending and cutting machine in 3 dimensions. There is no single machine made to perform both bending and cutting operations for such a small diameter. This paper gives the brief description about the design and construction of the pipe bending machine which is used to bend and cut metal pipes. Our objective is to increase accuracy at low price without affecting the pipe bending productivity. Using this machine both bending and cutting of pipe of outer diameter 6.35 mm and thickness 2.1 mm is possible. The machine is capable of bending the pipe in 3D at various angles (2-180 degrees). Equipped with electric motor driven feed mechanism, the system offers high speed and high accuracy bending, with lower power usage. The innovation in this machine is its hydraulically operated rotatory cylinder and draw tube used to grip the work piece. This innovation in the machine design gives an opportunity to reduce cost and also to reduce the human efforts. The automated bending system provides consistent, high-quality parts and process reliability while eliminating time-intensive, manual handling of many operations.

 Abstract

Human beings are created by the nature with an inherent right of freedom, equality and dignity. But the this very law of nature is infringed by the people in the form of various crimes done against the human being and one such crime is Human trafficking. Human trafficking is just another name for modern-day slavery, wherein the numbers of peoples are involved in forced, coerced and deceived labor and sexual exploitation. The figures are very scary and increasing day. Almost 6, 00,000 to 8, 00,000 women and children are annually trafficked across national borders of the nation. The vulnerable group of children and women are drag into the trap of traffickers and they are not permitted to leave upon arrival at their destination. They are held over these places against their will through acts of physical violence or coercion and are forced to provide services to the traffickers themselves or to the people as said by these traffickers. The work or services may include anything from bonded or forced labor, begging or the commercialized sexual exploitation. Sometimes this arrangement may be structured as a work contract, but with no or low payment or if it is on terms and terms are highly exploitative. Sometimes the arrangement is structured as debt bondage, with the victim not being permitted or able to pay off the debt. The root cause of trafficking may vary from poverty or economic insecurity, structural inequality to culturally sanctioned practices. In India human trafficking can be seen highly across the border areas on the Eastern side. On the eastern side India is chiefly bordered by Bangladesh and Nepal and this pave a route to the traffickers to reach their motive of trafficking. Every year large number of people crosses over to the Indian side from Nepal and Bangladesh. Uttarakhand, Assam and Meghalaya act as the chief entry points from this illegal immigration. The illegal immigration overlaps human trafficking in some cases especially in the case of women since sometimes women are forcibly pushed across the border either by offering them a bright career, good Job opportunity or sometimes they are drag off due to false friendship or love affairs. Human trafficking is proved to be a modern form of slavery because it includes the most inhuman of practices which go against the very ideals of life of dignity of a free man as envisaged in the UN charter and various other legislation of the nation. It is also seen as a threat to the security and integrity of a country. Hence every feasible measure must be taken along the lines by successive governments to wipe out this menace from the face of this planet.

 Abstract

Presently Bore well is very important and popular water source in India for household and also horticulture field. The bore well penetrating is done with the accessible highly cost machine. The normal size of bore well boring in India changes from 2 to 5 inches. Bore wells are deep long and the submersible pump is at the base of the long bore well pipe. Regularly the bore well pipe and pump are lifted out of the bore well utilizing which and pulley block. This is mostly time consuming and difficult work with labor. The bore well pipe lifter and transportation machine gives more than 3m/min transfer rate which makes the mounting and getting off of the submersible pump in bore wells quick and simple.

In Data Mining, Clustering is one of the recently and challenging tasks it support wide range of unsupervised classification application. Fast and high-quality document clustering algorithms play an important role in helping users to effectively navigate, summarize and organize the information. In this paper, we present a hybrid Particle Swarm Optimization (PSO) + Rough K-means algorithm that performs fast document clustering. This proposed method utilizes the Hadoop and MapReduce framework which provides the distributed storage and analysis to support wide range of distributed applications. Here we use the BBC dataset for clustering which contains 100 documents.
