  • Harmonic convergence for balanced and unbalanced non-linear load using
           hybrid filter
    • Authors: Shabana Urooj, Shirsendu Das
      Pages: 109 - 117
      Abstract: A control strategy is suggested for converging harmonics with hybrid filter. The hybrid power filter is constituted by a series active filter and shunt passive filter. The control algorithm works on dual formulation of electric power vectorial theory. Without depending on the system impedance, the active filter improves the compensation characteristic of the shunt passive filter and eliminates the series/shunt resonance problem, the voltage waveform injected by the active series filter is able to compensate for reactive power, eliminates harmonics in load current and balances asymmetrical load.

  • Research on improved convergence co-evolution genetic algorithm for
           TSPs
    • Authors: Shabana Urooj, Shirsendu Das
      Pages: 118 - 126
      Abstract: When the genetic algorithms are applied to solve travelling salesman problems, they are often faced with the problems of early convergence and being trapped in a local optimum. On the basis of co-evolution strategy, this paper proposes an improved genetic algorithm, which dynamically adjusts its fitness function and the probabilities of evolution operator in order to reduce the possible individual inbreeding degradation, and then effectively controls the evolutionary process. Compared with typical genetic algorithms, this improved algorithm can improve the speed of convergence and obtains better performance. Finally, this algorithm is verified on the TSP problem in 144 cities in China. The simulation results show that the improved genetic algorithm has better global searching performance and uses less convergence time.

  • A quantitative analysis of the relationship of franchise value, implicit
           insurance and bank stability
    • Authors: Hongjian Qu, Zhou Liang, Huimin Qian
      Pages: 127 - 136
      Abstract: Recent studies have shown that endogenous self-regulatory effect of franchise value can improve bank stability. In order to test the endogenous self-regulation effect of Chinese commercial bank's recessive insurance system, this paper builds an econometric model which consists of franchise value, recessive insurance and bank stability, and then completes an empirical analysis through 16 listed Chinese commercial banks' unbalanced panel data during 2000-2011. The empirical results show that the self-regulatory effect of endogenous franchise value does exist; the recessive insurance covers all types of commercial banks. The recessive insurance system weakens the role of self-regulation of endogenous franchise value. The larger scale of the bank, the better robustness, government regulation enhances the stability of banks; Chinese listed commercial banks' capital leverage and operating leverage effect is not fully effective.

  • An expert system with neural network and decision tree for predicting
           audit opinions
    • Authors: Mehdi Sarikhani, Seyed Mojtaba Saif, Fahime Ebrahimi
      Pages: 137 - 148
      Abstract: Nowadays, expert systems being used in various fields have received a great deal of attention. Auditing is one such field, along with determining the audit opinion type. An expert system consists of a knowledge database and an inference engine. The objective of this research is to make an expert system that will be of help to auditors in predicting and determining the different types of audit reports. The expert system receives data or knowledge from financial reports and determines the types of audit opinions by using an artificial neural network and a decision tree as an inference engine. An expert system should be able to explain the solution, but presenting the reason for the results obtained with a neural network is difficult. This study attempts to provide a method that will present simple and understandable reasons for the results obtained with neural networks.

  • Design and implementation of JXTA-based P2P mobile learning
           environment
    • Authors: R. Raj Kumar, N.Ch.S.N. Iyengar, Changpeng Ji
      Pages: 149 - 166
      Abstract: The unification of internet with wireless devices means that mobiles have become the most indispensable part of human life. This makes mobile devices a great platform to carry out mobile learning applications such as m-learn which enables students to request information through their mobile phones. The proposed Juxtapose (JXTA) enabled with Android (Peerdriod) connects and provides functionalities that enable students to gather information about the availability of lectures, live streaming of lectures, recorded audio and video tutorials, information about books in the library, visual aided directions inside the campus with mobile JXTA connecting to the university server. M-learn has enhanced interactivity and hence information management can be achieved that facilitates on-demand information retrieval in an educational environment. The enhanced study provides attractive generic infrastructures that rapidly define and implement m-learn in university and information services when compared to traditional classroom learning.

  • Formalised definition of communicational spaces
    • Authors: R. Raj Kumar, N.Ch.S.N. Iyengar, Changpeng Ji
      Pages: 167 - 198
      Abstract: This article deals with the concept of communicational spaces and tries to renew, clarify and formalise it from mathematical, geographical and philosophical standpoints. Starting from the concept that space is constituted by communication, a mathematical formulation of space is sought. In a similar manner to quantum mechanics, the present deliberation attempts to provide more generalised theories of reality than did preceding theories of space. In some approaches, spaces are intrinsically constituted by metrics, mainly by definitions of distance. The triangle inequality seems to be constitutive for space; however, it might no longer be applicable in spaces mediated by internet communication. The recent shift to virtual spaces and recent redefinitions of thirdspaces in human geography lead to a fundamental reconsideration of what space is at all, including drawing on distant philosophies. Concluding, this paper posits not that manifoldness is embedded in space, but conversely, that space is a product of manifoldness.
