A rapid growth in E-Commerce market is seen in recent time throughout the world. With ever increasing popularity of online shopping, Debit or Credit card fraud and personal information security are major concerns for customers, merchants and banks specifically in the case of CNP (Card Not Present). The presents a new approach for providing limited information only that is necessary for fund transfer during online shopping thereby safeguarding customer data and increasing customer confidence and preventing identity theft. The method uses combined application of Steganography and visual cryptography for this purpose. The proposes a technique of processing the signature of a customer and then dividing it into shares. Total number of shares to be created is depending on the scheme chosen by the bank. When two shares are created, one is stored in the bank database and the other is kept by the customer. The customer has to present the share during all of his transactions. This share is stacked with the first share to get the original signature. The correlation method is used to take the decision on acceptance or rejection of the output and authenticate the customer.

On the basis of density functional theory, we study the electronic structures of (3,3), (4,4), (5, 0) and (6, 0) SWCNTs. The results show that the cohesive energy of armchair tubes are larger than those of zigzag ones. The calculated band gap of (4,4) is smaller than those of other tubes. Moreover, the band gap for armchair tubes are smaller than those of zigzag. The variation of ionization potential, electron affinity, and Fermi energy level as the number of atoms in the tube grows up. This curve fluctuates strongly because of the change in size that produce different surfaces with different properties. The IP is larger than the EA, as is the normal situation for molecules. The highest number of degenerate states in the conduction and valence bands are about as follow: 7, 9, 9, and 7 for (3,3), (4,4), (5,0) and (6,0) CNTs, respectively.

Railway prestressed concrete sleeper is an imperative for component of ballasted railway tracks. Its main function is to help distributing axle loading to sub grade and formation. By nature, the concrete sleeper is subjected to sagging moment at the rail seat zone and to hogging moment at the middle section. Although behaviours of concrete sleepers under static loading have been enormously studied, their rotational characteristic and capacity under such loading have never been reported. The emphases of this paper are placed on the static behaviour and rotational capacity of a prestressed concrete sleeper under hogging moment. An Indian manufactured concrete sleeper was used in the experiment in accordance with Indian Standards, IS:2386-1963. LVDT was mounted at the middle span for measuring the deflection. The inclinometers were installed coincident with rail gauge in order to measure the rotations at those positions. Strains at bottom and top fibres under loading were recorded by strain gages. In this paper, the load-deflection curve of the static four-point loading test is presented. Relationship between hogging moment and gauge rotation is underlined. Criteria of the measure based on the loading capacity are also discussed for determining the failure of railway prestressed concrete sleeper. In this study the fly ash based geopolymer concrete mix design was obtained for M50 grade. The fluid to fly ash ratio was fixed as 0.45. The ratio of sodium silicate to sodium hydroxide was 2.5 and the concentration of the solution is 14 molar. The preliminary tests were carried out for the geopolymer concrete and conventional concrete and optimizing the mix design. Two numbers of sleepers were cast in each case one in conventional concrete and other one in geopolymer concrete. All the sleepers were tested under static monotonically loading and the results will be presented. Comparison will be made between conventional concrete and geopolymer concrete.

To improve the system performance in wireless P2P networks such as ad hoc networks and mesh networks. To design and implementation of cooperative cache in wireless P2P networks, and propose solutions to find the excellent place to cache the data. Utilizing the novel asymmetric cooperative cache approach, where the data requests are transmitted[1] to the cache layer on every node, but the data replies are only transmitted[1] to the cache layer at the intermediate nodes that need to cache the data. This solution not only reduces the suspension of copying data between the user space and the kernel space, it also allows data pipelines to minimize the end-to-end delay.

The removal of the residual dyes from waste effluents of dyeing is mandatory to achieve safe disposal to water body particularly in case of heavy metal complex dyes such as the industrial colorant Isolan Dark Blue 2SGL-01 (IDB). The adsorption of IDB was studied on the newly reported calcined (CO3)0.22/Cl0.55-Mg3.67Zn0.26Al layered double hydroxide (CLDH10) from aqueous solutions. The adsorption parameters; initial pH, equilibration time, dosage of adsorbent and concentration of IDB, were studied. Optimum pH for adsorption was at pH=8.7 and time of shaking 6 h. A pseudo-second order rate kinetics was observed for the adsorption process which follows the Langmuir-type adsorption isotherm with a monolayer capacity of 423.7 mg g-1. CLH10 was confirmed to efficiently remove > 99% of IDB. The loaded IDB was recovered in a single-batch process from CLDH10 with an elution efficiency of 29.4% using 1 mol L-1 Na2CO3 at 50 ºC.

Electrocardiography is the recording of electrical activity of the heart. Existing methodology focuses on diagnosing cardiac abnormalities by using xml ontology to identify the type of disease acquired. A schema of ontology is generated on basis of cardiac diagnosis report prediction with start, peak and end points of the ECG curve measured with its x and y axis positions. A xml schema is the description of type of xml document typically expressed in terms of constraints on the structure and contents of the documents. A xml schema is generated from the generated ontological schema records for easy mapping for the input electrocardiographic data. The resultant of existing system is the diagnosis report of input electrocardiographic data. The resultant sort out the possible abnormalities with the advent of the pulse rate estimated in the ECG curve.The proposed system incorporates the technique of automatic generation of diagnosis report with the ECG image. A validation process is incorporated in the proposed system to remove the noisy information from the inputted image as it deceives the accuracy of the diagnosis report. An ontological schema is used to identify cardiac prediction of curves. Existing system involves inappropriate diagnosis as the inputted image may contain noisy information which may lead to false disease prediction. The proposed system overcomes the problem of false disease prediction by validating the image using histogram validation.

Wireless sensor networks (WSNs) distribute nodes with the limited capabilities to sense, collect, and distribute information in numerous applications [1]. As sensor networks become pervasive, security is exposed to several attacks such as Sybil attack, network eavesdropping, masquerade attack, etc. For secure communication between the nodes, secret key cryptosystem is used. To deliver data in a secure manner without being compromised by an adversary, WSN provides secure communication and key distribution. Key management schemes have been established to achieve security. The tradeoff between the security and the connectivity is explained in each key management scheme. By this survey, it helps us to know the schemes that detect attacks and prevent it. As we recuperate the merits and demerits of the schemes are analyzed. Moreover, the techniques and methods used have been summarized.

Ground magnetic data at Industrial Layout Orile Igbon was analyzed with a view to determining the areas that are competent for the construction of factories and other related buildings (e.g. high-rise administrative buildings). The study area falls within latitude 080 13′ 59.22″ to 080 15′ 0″ North and longitude 0040 17′ 05.0″ to longitude 0040 19′ 01.1″ East of Southwestern Nigeria. The ground magnetic survey was carried out, the acquired data was processed and analyzed. The qualitative interpretation revealed features like faults, contact between two rocks and fracture zones. However, the quantitative interpretation gave the overburden thickness to the top of the magnetic basement rock as varied between 6.0 and 33.5 m. Interpretation of ground magnetic data revealed that Industrial Layout Orile Igbon comprise of zones underlain with thin as well as thick overburden. It is therefore advisable that people should not ignorantly built factories making use of heavy machines where there is thick overburden as it might lead to subsidence or total collapse in the future. This could occur when the vibration of these heavy machines is transferred to the subsurface which might lead to ground motion which later has effect on the factory’s foundation.
