MAIL SORTER USING LABVIEW
Get PDFThe Indian postal system is the largest networks in the world. Being the 7th largest country in the world, major population of the country is rural based, where the basic amenities of life is a sweet dream. In such a scenario, having an efficient mail delivery system is essential. Hence, to eliminate the drawbacks in other processes, we propose to fully automate the sorting process. Unlike the code generation technique, it neither requires any human intervention to generate a code based on the pin code nor will be a problem in case of absence of the pin code. The principle used for sorting is the Optical Character Recognition using LabVIEW software. Camera, placed over the slide unit captures the image of the address. The pin code or the state (in the absence of the pin code) is selected and compared with a set of trained characters in the data base. On finding a positive match, based on the first two digits of the pin code or the first four letters of the state, the mail is segregated by the LabVIEW program involving OCR technique. The processed data is sent to the real time application by the DAQ card, which activates the actuating arm(servo motor) to allow the letters to move to the respective stack(zone) and thus sorting the mails automatically, reducing the human effort and errors
Seamless Handover between UMTS and GPRS
Get PDFUMTS is one step ahead from the 2.5G network GPRS and supports faster data rates with wide coverage area. GPRS and UMTS are already deployed in many countries but seamless handover between GPRS and UMTS still remains as a stumbling block for the service providers to fulfill the continuously increasing customer demand for internet and data access in the IP-based wireless network and to maintain incessant connection for the itinerant service consumers. In this paper we propose a method that mongrelizes 3GPP IMS and MIPv4 to resolve the seamless inter-system handover between UMTS and GPRS with a result of no packet loss and minimum latency so that the itinerant service consumers can get services without any interruption
A MOBILE PAYMENT SYSTEM THROUGH INDEPENDENT M-SIGNATURE SERVICE
Get PDFNowadays a great number of applications require the use of Electronic Signature (e-signature) and nonrepudiation services such as certified e-mail, contract signing, electronic payment system and etc... The authenticity and integrity generated by e-signature in electronic document is like a handwritten signature in the paper document. The mobile user would be able to use any application that requires an e-signature is called as Mobile Signature (m-signature). Msignature can be created by different ways, such as Server-based signatures, Mobile Signature Service (MSS), Mobile Signature Application Unit (MSAU). But those have several limitations. In this work, we present the implementation of mobile payment system using m- signature service to an insurance company and for a mobile shop
SEARCH ENGINES USING EVOLUTIONARY ALGORITHMS
Get PDFA subset of AI is, evolutionary algorithm (EA) which involves evolutionary computation, a generic populationbased meta heuristic optimization algorithm. An EA uses some mechanisms inspired by biological evolution: reproduction, mutation, recombination, and selection. A genetic algorithm (GA) is a search technique used in computing to find exact or approximate solutions to optimization and search problems. Working of a search engine deals with searching for the indexed pages and referring to the related pages within a very short span of. Search engines commonly work through indexing. The paper deals with how a search engine works and how evolutionary algorithms can be used to develop a search engine that feeds on previous user requests to retrieve alternative documents that may not be returned by more conventional search engines
A TOOL FOR EFFECTIVE DETECTION OF FRAUD IN CREDIT CARD SYSTEM
Get PDFDue to the rise and rapid growth of E-Commerce, use of credit cards for online purchases has dramatically increased and it caused an explosion in the credit card fraud. Fraud is one of the major ethical issues in the credit card industry. As credit card becomes the most popular mode of payment for both online as well as regular purchase, cases of fraud associated with it are also rising. In real life, fraudulent transactions are scattered with genuine transactions and simple pattern matching techniques are not often sufficient to detect those frauds accurately. Implementation of efficient fraud detection systems has thus become imperative for all credit card issuing banks to minimize their losses. Many modern techniques based on Artificial Intelligence, Data mining, Fuzzy logic, Machine learning, Sequence Alignment, Genetic Programming etc., has evolved in detecting various credit card fraudulent transactions

DIRECT TORQUE CONTROL FOR DOUBLY FED INDUCTION MACHINE-BASED WIND TURBINES UNDER VOLTAGES DIPS AND WITHOUT CROWBAR PROTECTION
Get PDFThis letter proposes a rotor flux amplitude reference generation strategy for doubly fed induction machine based wind turbines. It is specially designed to address perturbations, such as voltage dips, keeping controlled the torque of the wind turbine, and considerably reducing the stator and rotor over currents during faults. In addition, a direct torque control strategy that provides fast dynamic response accompanies the overall control of the wind turbine. Despite the fact that the proposed control does not totally eliminate the necessity of the typical crowbar protection for this kind of turbines, it eliminates the activation of this protection during low voltage dip
A HIGH-PERFORMANCE AND LOW-POWER DELAY BUFFER
Get PDFIn this paper, presents circuit design of a low-power delay buffer. The proposed delay buffer uses several new techniques to reduce its power consumption. Since delay buffers are accessed sequentially, it adopts a ring-counter addressing scheme. In the ring counter, double-edge-triggered (DET) flip-flops are utilized to reduce the operating frequency by half and the C-element gated-clock strategy is proposed. Both total transistor count and the number of clocked transistors are significantly reduced to improve power consumption and speed in the flip-flop. The number of transistors is reduced by 56%-60% and the Area-Speed-Power product is reduced by 56%-63% compared to other double edge triggered flip-flops. This design is suitable for high-speed, low-power CMOS VLSI design applications
