A New Feature Extraction Technique For Classifiers Using Self-Organizing Map
by Prasenjit Dey, Tandra Pal
Abstract: Neural network classifiers suffer from the overfitting problem which reduces its generalization capability. Due to generalization, a trained classifier will always have good test accuracy. The objective of the proposed work is to improve the input space of the data set which in consequence will increase the generalization of the classifiers. For this purpose, we have proposed a new feature extraction technique based on self-organizing map (SOM). Initially, two-dimensional SOM network is trained to achieve topological ordering in the input data set. Then, a Gaussian function is used in each node of the output map of SOM network. It processes the input patterns sequentially and produces $m^2$ dimensional new representation corresponding to each input pattern, where $m^2$ is the number of nodes present in the output layer. Thereafter, classifiers like probabilistic neural network (PNN) or multilayer perceptron (MLP) is used over this new representation of the input patterns. The whole process creates a new classifier based on hybrid neural network model. We have used twelve standard classification data sets and compared proposed model with conventional PNN and MLP classifiers. Comparison of results shows the superiority of the proposed method. Wilcoxon signed rank test also shows that our SOM-based model used for transformation of feature representation improves the performance of the classifiers.

by Smita Rani Parija, Prasanna Kumar Sahu, Sudhansu Sekhar Singh
Abstract: In mobile access networks, location management is a major and complex issue where location information of the mobile user is essential to deliver incoming calls/SMS to the appropriate mobile stations (MSs). Many metaheuristic algorithms are developed to solve such types of important issue which is responsible for determining the network configuration. This paper proposes a conventional binary genetic algorithm (BGA) approach implemented to reporting cells planning problem in complex multimodal search spaces. Since BGA is a conventional algorithm sufficiently able to solve the signalling cost problem along with the modifications in the generic operators. These modifications occur in the mutation operator. The simulation results obtained from the experiments conducted using the existing database along with the real time database. The proposed method shows better performance compared to existing algorithm. This simulation results obtained from the experiments reflects the effectiveness of the conventional BGA.

Singularity preserving collocation methods for weakly singular Fredholm integral equations and the corresponding eigenvalue problem
by Bijaya Panigrahi
Abstract: In this paper, the singularity preserving collocation methods are being developed for Fredholm integral equations of the second kind with the weakly singular kernel and for the corresponding eigenvalue problem. In this method, the interpolatory projected space is the direct sum of singular space and spline function space. The convergence rates for the approximated solution and iterated solution in weakly singular Fredholm integral equations of the second kind are being calculated. The error bounds for eigenvectors, eigenvalues, and iterated eigenvectors are also being obtained. We illustrate our results with numerical examples.

by Bijay Baran Pal, Mousumi Kumar
Abstract: This paper presents a multiobjective bilevel programming (MOBLP) based interval goal programming (IVGP) method for modeling and solving to solve environmental-economic power generation and dispatch (EEPGD) problem using genetic algorithm (GA) in an inexact environment. In the proposed method, the objective functions to be optimized are represented as goals by introducing target intervals for the achievement of objective values in decision horizon. Then, using interval arithmetic rules, the defined planned -interval goals are converted into standard goals as in conventional goal programming (GP) to formulate minsum IVGP model of the problem. In the solution search process, a genetic algorithm (GA) computational scheme is employed in an interactive way to reach the solution of EEPGD problem
The effective use of the approach is illustrated through a case example of the standard IEEE 30-Bus 6-Generator test system. The model solution is also compared with the solutions obtained by using other approaches studied previously.

by Ioannis Argyros, P. Jidesh, Santhosh George
Abstract: The aim of this paper is to extend the usage of a third order method based on the Adomian decomposition in cases not covered before. The hypotheses are based only on the first derivative while in earlier works, hypotheses requiring the existence of the fifth derivative are utilized to show the convergence of the method. Moreover, we also provide radii of convergence as well as error estimates based on Lipschitz constants not given before in earlier works. Numerical examples emphasizing the superiority of the new results over the earlier ones complete this paper.
Keywords: Adomian decomposition method ; Newton’s method; order of convergence; local convergence.

Permeate stream produced by the membrane are good quality due to this membrane found wide application in the field of water purification, gas-gas separation etc. In the concerned study, the ability of the cellulose acetate disc membrane for improving the quality of the rubber industrial effluent of Tripura has been investigated in pilot scale. GMDHmultilayered feedback algorithm has been implemented to predict the maximum efficiency of the membrane. The efficiency of the membrane is maximized for the optimal value of pore size, inlet velocity, and operating pressure. It has been found that efficiency of the membrane is maximized when the pore size of the membrane is kept 2.060538 μm, inlet velocity is 0.201896 m/sec and operating pressure is 694.7201 kPa. The performance of the prepared GMDH model is evaluated by using model evaluation technique like NSE, PBIAS, slope and Y-intercept, RSR.

Wheat Yield Forecasting Using Fuzzy Logic
by Tanya Sah
Abstract: Forecasting in general and crop yield forecasting, in particular, is considered a compound problem. Food and Agriculture Organizations report Global Agriculture towards 2050 accentuates the challenges which agriculture sector is going to face in near future. The report draws the attention towards the disparity between the demand and supply. It also highlights the issues that automation has introduced into the food and agriculture sector. Where there is a need to increase the production to feed the rapidly increasing population there is an equal necessity for coping up with the dwindling numbers of farm workers. As such, there is a need for a reliable forecasting algorithm capable of handling time series data. In this paper, we have proposed a fuzzy time series forecasting algorithm to forecast wheat yield. The reason to choose fuzzy over other forecasting methods is its capability of dealing with the vague, imprecise data and it outperforms many statistical conventional models in such conditions. The neural network has been used for training and defuzzification of the forecasted values.To attests the efficacy and the performance of the proposed method, it has been tested against the wheat production dataset.
Keywords: Fuzzy Logic; Wheat yield forecasting; Neural Network.
A novel method for reduction of leakage current in MOSFET
by Debasis Mukherjee, B.V.Ramana Reddy
Abstract: In this paper, structural modification of conventional bulk MOSFET has been proposed for minimization of subthreshold leakage current. Key structural features of bulk MOSFET have been kept unaltered. Comparison of conventional and proposed structure has been presented for a 20 nm NMOS with 0.8 volt Vdd. The proposed structure is capable of reducing subthreshold leakage current even at very low drain voltage when the gate voltage is zero. Around 55 percent reduction of OFF current has been obtained when drain voltage is at Vdd and gate voltage is zero. The methodology proposed does not have any special requirement at the circuit level, and can be combined with all circuit level methodologies. The proposed structure is named as Defensive MOSFET as it looks like a defensive shield. Structural dimensions of 20 nm MOSFET generation have been taken from the 2011 edition of International Technology Roadmap for Semiconductors or ITRS. All simulation processes have been executed by Sentaurus G-2012.06 Technology Computer Aided Design or TCAD software.
