Abstract :

Nowadays, banks and financial institutes have experienced a transition toward electronic banking leading to larger number of customers and huge amount of transactions. As a result of these changes new issues and challenges emerge which necessitate deep investigation of data. One of these challenges is examining customers’ behavior and identifying anomalies so that fraud could be detected. On the other hand, exact investigation of huge transaction data is not possible using conventional methods. Therefore, financial institutes are seeking for novel solutions enabling them to detect anomalous behaviors rapidly. In this paper a novel solution is proposed based on data mining and artificial intelligence. For this purpose, fuzzy expert systems and genetic algorithm are utilized. First off, data collected from transactions are analyzed to extract behavioral features. Afterwards, these features are converted to fuzzy rule base of the proposed fuzzy expert system. Subsequently, the resulted fuzzy rules are optimized using genetic algorithm. In the proposed genetic algorithm, crossover and mutation operators are defined in fuzzy form which significantly improves their efficiency and convergence speed.

Abstract :

This paper present the experimental design of an energy harvesting system using active materials for power generation from the shoe sole. The active material as PZT has been employed and modified to be appropriately embedded in the shoe sole. When the mechanical pressure is applied to the embedded shoe sole while walking would extract mechanical vibration energy and convert extracted energy to electrical energy directly from the piezoelectric structure inserted in shoe sole via a rectifier to a power processing system. The power processing system regulates the harvested electrical energy and accumulates the generated electrical energy to sufficient voltage level for powering portable electronic devices for later use. In this paper we show the simulation and experimental results of energy harvesting circuit and efficiency of the extracted ambient vibration energy by PZT in terms of electrical voltages during single step and continuous walking for a period of time.

Abstract :

Due to the global warming problem, it is more urgent than ever to take carbon emission problem seriously. It is needed to take carbon emission cost into consideration. Gravity method is used to do location selection. Three aspects of work have been done. First, the carbon emission cost of a certain kind of truck is calculated. Second, the comparison between considering and not considering carbon emission is done. Third, a distance parameter is added to transfer straight-line distance to real distance. The research gets the result in two cases: case 1 single mode transportation tools are used, the best site has no changes with total cost rising; case 2 multi-mode transportation tools are used, the best site coordination has changed with cost rising in general except extraordinary case. At the end, we show the application of the model. The carbon emission cost affects the location modeling, the cost like carbon dioxide tax will drive the location center to move a little bit in the direction of the CO2 efficient area towards less efficient area.

Abstract :

A cognitive radio is a capable Technology, which has provided a great innovation in wireless communication system as to improve the efficiency of the electromagnetic spectrum utilization in wireless network. The technology allows unlicensed user or secondary user to use the vacant spectrum of licensed user through dynamic channel assignment strategies to improve the spectral utilization and hence cognitive radio avoids spectrum shortage. Cooperative sensing is one of the fastest growing areas of research and it is likely to be a key enabling technology, for efficiently spectrum sensing in future. For this several spectrum sensing are available, which can detect the white spaces or spectrum holes and share them to the secondary user without interfering with the movement of licensed user. In order to reliably and swiftly detect spectrum holes in cognitive radios, optimization must be used. In this paper we study different optimization for spectrum searching and sharing and also compare this optimization on the basis of probability of total error on fading channel.

Abstract :

This is exploring the impact of the internet on local community involvement in Tehran, Iran. It investigates how the internet changes community involvement and argues that the Internet has created new forms of community involvement instead of local community involvement. This study has employed quantitative research methods. The sample for this research was drawn from the population of Internet users, namely people who accessed and used the Internet in Tehran, Iran. The results of the study indicate that there was no significant correlation between the amount of Internet use and local community involvement. People who spend more time online (high Internet user) do not have a greater local community involvement than people who use Internet less of the time. By contrast in terms of type of Internet use and social capital the study found that people who used the Internet for local news and reading newspapers online were more involved in the local community. The study illustrated that the Internet encourages people to some extent to become involved in the national or global community.

Title : Estimation of The Relationship Between The Travel Time of Flood Peaks and Peak Discharge on The Poprad River by Multilinear Flood Routing

Abstract :

The empirical relationship between travel-time of flood peaks and peak discharge was studied on a reach of the Poprad River in Slovakia. The data were fitted by regression and compared with the expected shapes as described in the literature. Further a chain of linear segments has been considered as the model of that relation. The number of segments parameters and the angles between theses in this piecewise linear model were fitted by optimisation of a conceptual multilinear flood routing model performance on a large flood wave with the help of a genetic algorithm. In the setup of the multilinear model the travel-time parameter of the model was allowed to vary with discharge according to the piecewise linear model of the travel time of flood peaks. The discrete state space representation of the Kalinin-Miljukov model was used as the basis for a multilinear discrete cascade flood routing model. The resulting relationship was compared with empirical data on travel times and used to model the variability of the time parameter in the discrete state space representation of the Kalinin and Miljukov model on three verification floods. The modelling results showed that the inclusion of empirical information on the variability of the travel-time with discharge even from one flood enables satisfactory accuracy for the prediction of the flood propagation process.

Abstract :

In today’s competitive world, customers are at the center of companies’ attention. Customer loyalty is a pivotal element of gaining competitive advantage. The creation of customer loyalty is a concept that contemporary businesses have paid significant attention to it. Despite the abundant of studies done on one-dimensional loyalty and two-dimensional loyalty (behavioral and attitudinal), there unfortunately exist few number of studies on loyalty with three or four dimensions. As a result, there is insufficient amount of literature in this regard. In this study, therefore, an investigation of the evolution of loyalty throughout time, from one dimension to four dimensions, is carried out together with a definition of the concept.
