 Abstract

Currently, the differential function has been widely used in transformer protection relay. However, the main issue of this technique is assigned to the relay mis operation during the presence of inrush currents and current transformer (CT) saturation. In the literature, these limitations have been overcome with the use of tools based on artificial intelligence and signal processing, such as the methods based on artificial neural networks and wavelet transform. This paper proposes a method based the ANNs and wavelet transform to detect and classify disturbance in the power transformer accurately. The algorithm uses wavelet based disturbance detector in order to detect any disturbance related to a power transformer, whereas a neural network based routine is used to classify the disturbance type (internal fault, external fault and transformer energization) appropriately, as well as to classify the internal faults. Several events were simulated, such as external and internal faults, with variations of fault resistance, fault inception angle, and fault type parameters, as well as transformer energizations. The method presented an excellent success rate regarding the correct classification of the disturbance as well as an accurate fault classification.

 Abstract

Smart contracts are is a self-executing contract that automatically executes when pre-defined conditions are met including financial services industry. Smart contracts, which are enabled by blockchain or distributed ledgers, have been held as a solution to many of the issues associated with traditional financial contracts, which are simply not designed for the digital age. Financial intermediaries raise overhead expenses and enhance regulatory requirements while enabling interoperability for the financial system and lowering risk. This concept aims to adopt smart contracts that will lead to reduced risks, lower administration and service costs, and more efficient business processes across all major segments of the financial services industry.

 Abstract

Online FIR System is the Computerization of present manual system of Police Stations. There are many flaws and shortcomings in the present system. The present system is a manual system. In case of present manual system all the record is kept in documented form and stored in various types of registers. The manual system has no proper system for record storage and storing the information about crimes and criminals. The present system of police is not automated. The documentation of criminal records is done manually. Case files are dumped in heaps while some are kept on shelves. These important documents quickly get dusty and because of lack of proper storage, some criminal documents are seriously damaged. With this kind of situation, it becomes highly difficult and even impossible to track down known criminal, access past criminal history of a suspect and know the status of some concluded cases. In police stations all the file work is done by the staff, so burden of work leads to the criminal's information to be delayed. There are also problems of record storage, updating, backup and recovery and redundancy of data. To overcome the problems in present system we design such a computerized information system, which is free of all the flaws, present in the manual system of the institute. As computer is one of the leading technologies nowadays, so we propose a computer-based system that will fulfill the requirements of the police stations easily and will be the solution to the problems faced by Police stations. It will facilitate both the user as well as administrative staff of the Police Stations. Computerized system provides accuracy, security, and reduced redundancy, reduction of work load, backup facilities and faster information retrieval.

 Abstract

This paper is analysis problem in logistic transportation, empty truck problem and importance of route planning Logistics transportation between cities are subject to considerable slow queues and congestion, revealing a lack of medium and/or short-term logistic planning. One of the causes is the number of trucks travelling with empty containers, performing one-way trips, from one city to another city. This issue may be reduced by combining trips, i.e., after bringing goods to the (export trip), a truck should, when possible, carry goods from that city to the origin or a nearby city (import trip). We investigate a combinatorial optimization drawback wherever a collection of import/export/inland journeys should be combined so as to reduce total traveling time, that successively reduces the amount of empty trucks traveling to/from the cities. Traffic blockage wastes time, energy, and causes pollution. during this paper, we have a tendency to propose associate application taking advantage of transport communications, specifically dynamic route planning. In dynamic route arranging, the route from a travel origin to its destination, rather than being statically decided at the travel beginning time, is occasionally recomputed according to real-time traffic information. Also, This paper investigation the issue almost the transportation in logistics. And proposes the idea to decrease transportation cost and increment client fulfillment by applying ITS (intelligent transportation system) technology and the other technologies.

 Abstract

Fault classification is necessary for reliable and high speed protective relaying followed by digital distance protection. Hence, a suitable review of these methods is needed. The countless extent of power systems and applications requires the improvement in suitable techniques for the fault classification in power transmission systems, to increase the efficiency of the systems and to avoid major damages. The paper analyzes the technical literature, summarizing the most important methods that can be applied to fault classification methodologies in power transmission systems.

 Abstract

The persistence of E-commerce Mobile Application for Local Store is to mechanise the current manual Application by the help of computerized tools and developed Mobile Application, fulfilling their requirements, so that their appreciated data/information can be stored for a longer period with easy accessing and manipulation of the same. The required software and hardware are easily presented and easy to work with. Online E-commerce Application, as described above, can lead to error free, secure, reliable and fast management Application. It can assist the user to concentrate on their other activities rather to concentrate on the record keeping. Thus it will help Stores in better utilization of resources. The Stores can maintain computerized records without redundant entries.
