To make banking more comfortable, Banks make the Interbank Networks, by that the usage of ATMs of the non native users also increases. Interbank Network provides so many services, in them the effective one is usage of non native ATM service up to certain times without paying the surcharge, which is better service and not fulfilling due to missing of some elementary representation. This paper informs the problem along with the solution, which is in the form of Transaction counter. © 2012 Springer-Verlag.

Human beings can easily categorize a person’s age group from a facial image where as this ability has not been promising in the computer vision community. To address this problem very important area of research, the present paper proposes a novel scheme of age classification system using features derived from co-occurrence parameters using Rank based Edge Texture Unit (RETU). The Co-occurrence Matrix (CM) on RETU characterizes the relationship between the neighboring edge values, while preserving local information. The novelty of the proposed RETU is it classifies the age of human into seven categories i.e. in the age groups of 1–10, 11–20, 21–30, 31–40, 41–50, 51–60, and greater than 60. The TU of the proposed RETU ranges from 0 to 17 and thus reduces overall complexity in evaluating features from CM. The co-occurrence features extracted from the RETU provide complete facial image information for age classification purpose. The RETU reduces each 3 × 3 sub image into 2 × 2 sub image while preserving the texture features and thus reduces the overall dimensionality of the image. © Springer India 2015.

The next generation wireless systems will consist of heterogeneous networks from cellular, Wi-Fi, WiMAX to other emerging access technologies. Vertical handoff occurs when a mobile terminal decides to switch between networks. One of the challenging problems during vertical handoff is the selection of an optimal network that maximizes end users satisfaction. This paper presents an intelligent vertical handoff decision algorithm that selects the target network based on the traffic class of the mobile user. The algorithm uses two modules, to estimate the handoff requirement and to select the optimal network. These modules utilize Fuzzy Logic and Genetic algorithm to make an intelligent vertical handoff decision.

Numerous studies demonstrated the possibility of utilizing fly ash in the construction of embankments, road subgrades and stabilization of a wide range of soils. The present investigation aims at determining the optimum fly ash (OFA) for mechanical stabilization of expansive soils. Four different soils were tested for compaction characteristics and unconfined compressive strength with and without the addition of fly ash to determine the OFA. The liquid limit (LL) and the fraction coarser than 425 μ (CF) of these soils range from 50 to 120 and 25 to 70%, respectively. An experimental strategy called two-factor factorial design was adopted in the conducting experiments. LL and CF present in the soil are the two factors considered to influence the OFA content. Factorial experimentation enables relative quantification of the effect of each factor as well as their interaction with the OFA. The OFA was found to range from 5 to 40% depending upon the two factors. The LL and the CF were found to have dominating influence on OFA content in that order, whereas the interaction effect of these two factors was marginal to fair. A statistical regression model was developed for determination of the OFA in terms of the influencing factors. The validity of the model developed was verified by conducting laboratory tests on two more soils that were not used in the development of the model. Swell potential and swelling pressure of expansive soils were reduced to non-critical levels when treated with OFA. © 2011 Springer Science+Business Media B.V.

For using in multiple transmits antennas systems, a number of Quasi- Orthogonal Space-Time Block Codes (QOSTBC) has been proposed. Based on circulant matrix, in this paper, we propose a novel method of extending any QOSTBC constructed for 8 transmit antennas to a closed-loop scheme. We prove that the proposed scheme can improve its transmit diversity with one bit feedback, with the aid of multiplying the entries of QOSTBC code words by the appropriate phase factors which depend on the channel information. The optimal constellation rotated schemes as well as performances of the proposed scenario 8 transmit antennas QOSTBC are analyzed. The simulation results suggest that there is a significant Eb/No advantage in the proposed scheme which is able to be designed easily. © Research India Publications.
