Therefore a person gets less time to go for shopping. A person gives more preference to online shopping. In the technical world, online shopping refers to E-Commerce. There are many online E-Commerce sites available over web which deal with millions of transactions in a day. These websites deal with huge amount of data which must be maintained for analysing the daily/monthly/yearly transactions, profits and statistics. Data can come from different sources therefore there is a need to refine the data which gives accurate data statistics and provide better report. Here working of data service makes a sense. In this paper we will discuss how SAP data service can be used for E-commerce.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90432348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parameters change in a known range, but the probability is unidentified).The probabilistic mechanical approaches aim to give an estimation of the solution when the information on the parameters of analyzed problem is uncertain.For some mechanical problems with probabilistic parameters, a constraint to be satisfied is added. In engineering design, the reliability analysis is an example of such constraint.In this paper, and for static probabilistic-reliability analysis, an approach reducing the size of numerical computing is proposed. It will be validated on static discrete and continuous systems having probabilistic parameters.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72654515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Routing in Cognitive Radio Ad-Hoc Networks (CRAHNs) is a very challenging task due to diversity in the available channels. In this paper, Mobility and Activity Based Routing Protocol (MABRP), is proposed. In the proposed protocol, CUs discover next hops based on the collected spectrum and mobility information. In addition, using cooperative communication mechanisms to reveal new routing opportunities, enhance route qualities, and enable true coexistence of primary and secondary networks is investigated. The performance of MABRP and Cognitive Ad-hoc On-demand Distance Vector (CAODV) are evaluated on the basis of packet delivery ratio (PDR), end-to-end delay, routing overhead, and hop count in two different scenarios: mobile PUs scenario, and static PUs scenario. The availability of a routing channel dynamically varies in time due to the changes of the PUs relative positions. The performance evaluation is carried out using NS2 simulator. The simulation results proved that MABRP achieves better performance in terms of average PDR, with a slight increase in overhead and end-to-end delay in low PUs activity compared to CAODV routing protocol.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76021924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wave propagation constant becomes zero or negative under proper magnetic biasing which resist the antenna as radiator without a mechanical maneuvering. The fitness functions for the GA program have been developed using mathematical formulation based on nonreciprocal approach of ferrite substrate under external magnetic field.

In Medical image such as Ultrasound image are contaminated by different types of noise. The usefulness of US imaging is degraded by the presence of signal dependence noise known as speckle noise. In the presence of such noise it is difficult to diagnosis. To acquire a better performance we state another method that works efficiently to reduce noise an image without blurring the frontiers between different regions. This paper demonstrates wavelet based thresholding technique for de-noising and improving visual image quality in ultrasound images. This proposed method is compared to other existing approach and give superior result that satisfy the human visual quality and also these resulting images are evaluated by the performance parameter Signal to Noise Ratio, The Peak Signal to Noise Ratio and also other image quality measurement criteria.

Now a day’s India become cashless due to biggest decision ever taken of demonetization. Demonetization is a process in which .Cashless India is famous in current days which makes easier people’s life. People can easily do e-payments everywhere 24*7. People don’t need cash in their hands even Indian government also promote e-payments infrastructure. There is no need to carry even credit cards or debit cards when you have e-wallet. Government promotes UPI (Unified Payment Interface) and Paytm (pay through mobile) online applications with this every transaction are linked with your account and you can proceed to pay anywhere for shopping, paying bills and any online transaction over there. In this research paper light is thrown on these two folds: UPI and Paytm. How they works, their benefits and weaknesses and which one is more beneficial to use. Keyword: Overview, how they works, Benefits and weakness. I. Overview From past few years global payments are increasing day by day. Life is so fast that we always want to do everything fastly. Over the past 10years, smart phones seem to give us more power to perform whatever we want to do within seconds. People can’t afford to waste their time and can’t wait to perform their work manually. They need now one touch solution for everything whether it is for shopping, paying bills, online transactions etc. and all is now happening through the digital payments. The last two to three months heightened this to perform on a large scale because of demonetization. Everyone is facing problem of cash and our society becomes cashless society. But now with two helping payment systems that is UPI (Unified Payment Interface) which is launched by NPCI (National Payment Corporation of India) under guidance of RBI (Reserve Bank of India) and Pay tm( pay through mobile) launched by Fin tech in India and owned by one97 communications solve our problems of cash and helps to become a cashless society but with cash in their pockets. II. UPI (Unified Payment Interface) UPI is launched by NPCI which also launched IMPS(Immediate Payment system) online payment system.UPI is one step ahead to IMPS and it make society completely cashless and digital. UPI helps to perform our e-payments vastly through our smart phones. It is promoted by our government in these days on large scale especially by our PM Narendra Modi ji. He wants our society to be completely digital with the help of UPI system. It helps us to perform our transaction 24*7 from our accounts and avail the benefits of net banking. It helps to eliminate the use of multiple entries of our debit card or credit card details to perform transactions on the sites through which phishing and hacking is possible. III. Paytm (Pay Through Mobile) Paytm is a mobile app which is widely used and accepted by customers for their important cores like paying bills, fees, ticket bookings, mobile and dish recharges and shopping anytime","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78238242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
