1. An Overview on Taguchi Method
Author : Shyam Kumar Karna and Dr. Rajeshwar Sahai
Keyword : Taguchi method, P- diagram, orthogonal arrays, S/N ratio

Volume:1,Issue:1,PP:1 - 7,Year:2012
Optimization of process parameters is done to have great control over quality, productivity and cost aspects of the process. Off-line quality control is considered to be an effective approach to improve product quality at a relatively low cost. Analysis of variance (ANOVA) is used to study the effect of process parameters on the machining process. The approach is based on Taguchi method, the signal-to-noise (S/N) ratio and the analysis of variance (ANOVA) are employed to study the performance characteristics.
2. Instrumentation for Recording of Pc3 Magnetic Pulsations in South-East Australia
Author : I.A. Ansari
Keyword : Geophysical instrumentation, Pc3 Geomagnetic Pulsations, Magneto spheric Physics

Volume:1,Issue:1,PP:8 - 13,Year:2012
Pc3 magnetic pulsations are quasi-sinusoidal variations in the earth’s magnetic field in the period range 10-45 seconds. The magnitude of these pulsations ranges from a fraction of a nT (nano Tesla) to several nT (Ref.1). These pulsations can be observed in a number of ways. The most commonly used techniques are the following. (i) The magnetic components of the fluctuations are measured employing rapid run magnetometers. These include the flux gate Rb-vapour magnetometers. (ii) The time derivative of the magnetic components of the variations is recorded using induction coils. (iii) The potential difference induced by pulsation magnetic field between the electrodes buried in the earth is measured. The application of ground-based magnetometer arrays has proven to be one of the most successful methods of studying the spatial structure of hydromagnetic waves in the earth’s magnetosphere. With a few exceptions, the Pc3 studies undertaken in the past have been confined to middle and high latitudes. The spatial and temporal variations observed in wave polarization and signal phase are of vital importance because they provide evidence which can be directly related to wave generation mechanisms both inside and external to the magnetosphere and propagation modes inside the magnetosphere. At low latitudes (L  3) wave energy predominates in the Pc3 band and the spatial characteristics of these pulsations have received very little attention in the past. An array of four low latitude induction coil magnetometers was established in south-east Australia to study the characteristics of low latitude Pc3 magnetic micropulsations over a longitudinal range of 17º at L=1.8 and a latitudinal range of 10º over L=1.8 to 2.7. The recording instrumentation employed in the study has been described in this paper.
3. An Inventory Model for Time Dependent Deterioration, Selling Price Dependent Demand and Parabolic Varying Holding Cost
Author : Ramji Porwal and C.S. Prasad
Keyword : Deterministic Inventory models, selling price-dependent demand, deterioration, time-dependent holding cost, shortages, sensitivity

Volume:1,Issue:1,PP:14 - 21,Year:2012
In this study, a deterministic inventory model is developed for time varying deterioration with selling price dependent demand in which shortages are allowed and completely backlogged. Demand rate is taken a decreasing function of selling price. The traditional parameter of holding cost is assumed here to be time varying which is parabolic increasing function of time. At the end of the model, a numerical example is given and sensitivity analysis has been carried out for showing the effect of variation in the parameters.
4. Volume Thermal Expansion for Ionic Solids at High Temperatures
Author : B.S.Sharma , R.Kumar and S.K. Sharma
Keyword : thermal expansion; Ionic solids. PACS Nos; 65.70; 62.20

Volume:1,Issue:1,PP:27 - 33,Year:2012
A new relationship for the temperature dependence of the volume thermal expansion is formulated using the approach that volume thermal expansivity depends quadratically on temperature. The present model is applied for NaCl, KCl, MgO and CaO. The results obtained for volume thermal expansion are found to compare well with the available experimental data.
5. Segmented Modeling of ECG Signal by Using Hermite Basis Function
Author : Prakash Dixit
Keyword : Hermite basis functions, Segmented modeling, Electrocardiography signal

Volume:1,Issue:1,PP:40 - 46,Year:2012
In this paper, a new technique of modeling for the approximation of entire ECG signal is presented. The proposed method is applied on four different ECG beats. In most modeling methods, best approximation for the important part of the signal is done. But the entire ECG signal is important for the diagnosis of different diseases. The proposed method exploit the importance of whole ECG waves by performing a segmented based modeling using Hermite basis function. The presented method uses only the 5th order Hermite basis functions which considerably reduce the total parameters needed to represent the ECG signal in comparison with other Hermitian based methods. As the result shows the total error obtained in this method is very less than in comparison with similar non segmented method by using only 5th order of Hermite basis function. And the result shows that the segmented modeling method could keep the ECG information without distortion. This has a great impact in modeling the heart arrhythmias where a small error could mislead the diagnosis.
6. Role of Artificial Neural Network for the Stabilization of Non Linear System
Author : A.P. Cheema and Mohd. Sabir
Keyword : Artificial Neural Network

Volume:1,Issue:1,PP:47 - 54,Year:2012
Artificial Neural Networks are being counted as the wave of the future in computing. They are indeed self-learning mechanisms which don't require the traditional skills of a programmer. A Neural Network is a powerful data-modelling tool that is able to capture and represent complex input/output relationships. The goal of the present paper is based on the Adaptive Neural Network controller which is used to make a non-linear system stable while providing improved performance and robustness. This approach is successfully applied to numerous systems. The controller may need to be adjusted slightly when moving from the design model to the actual implementation due to a mismatch between the model and true system. There are also cases when a control system performs well for a particular operating region, but when tested outside that region, performance degrades to unacceptable levels. These issues are addressed by robust control design. In this paper we shall concentrate on the supervised control learning scheme for stabilizing the dynamical system.

8. A New Threshold Function for Image Denoising based on Wavelet Transform
Author : Sanjay Jangra and Sandeep Kumar
Keyword : Wavelet-transform; MATLAB, threshold function; PSNR; MSE

Volume:1,Issue:1,PP:60 - 65,Year:2012
The denoising of a particular image suffered from some noise is a long established problem in signal or image processing field. Many published techniques based on wavelet transform are available; each having its own assumptions, advantages and limitations. Most of the research work is focused on statistical modeling of wavelet coefficients and the optimal choice of thresholds. In this paper, a new threshold function is presented based on wavelet transform. This new threshold function has many advantages over other soft and hard threshold functions. The simulation results show that the proposed thresholding technique has better features in comparison with conventional methods when used with an improved thresholding function. It also shows that using the new threshold function for image denoising inherits the advantages of the hard and soft threshold function.

Author : Dr. Hambeer Singh, Dr. Sanjay Jain and Dr. A.K. Shrivastav
Keyword : Queuing System

Volume:1,Issue:1,PP:66 - 79,Year:2012
In this paper an attempt has been made to calculate the characteristics of M/G/1 model with exceptional arrival/service i.e. stationary waiting time, sojourn time, queue length and some other characteristics. An M/G/1 model, in which service time distribution in each busy period may depend on the number of customers who have been served in the same busy period, is called exceptional service model. We use the regenerative approach; with this approach we get characteristics in tractable forms.

Author : D.P. Singh & Sanjeev Kumar
Keyword : Order Level Inventory, Power Demand Pattern

Volume:1,Issue:1,PP:80-86,Year:(2012)
The inventory control deals with the determination of optimal stocks of commodities to meet demands in the force able future. Many items are perishable and cannot be stored for longer periods whereas many others can be safely stored for an infinite period without there being deteriorated. These variations can have an important role on the type of operating principles that should be used in controlling the system as reported in Zipkin [1]. Exiting inventory models differ in many ways, i.e. nature of demand, nature of the information available with decision making authorities at any given time, in relation to the costs associated with the system and in their physical properties such as size, weight and volume.
