This paper presents a classification system for cardiac arrhythmias using artificial neural network (ANN) with back propagation algorithm. Classifiers based on multi layer perceptron (MLP) and discriminant analysis study using XLSTAT statistical classifier software are thoroughly examined on the UCI machine learning data base for cardiac arrhythmias. For this multi class classification we used one against rest method to classify 16 different arrhythmias which include normal sinus rhythm, Ischemic changes, myo infarction, sinus bradycardia, sinus tachycardia, premature ventricular contraction, supraventricular premature contraction, bundle branch block, atrial fibrillation, atrial flutter, left ventricular hypertrophy and atrioventricular block. From exhaustive and careful experimentation, we reached to the conclusion that proposed MLPNN classifier ensures true estimation of the complex decision boundaries, remarkable discriminating ability and does outperform the statistical discriminant analysis and classification tree rule based prediction.

This article presents a numerical solution for the MHD flow of an electrically conducting non-Newtonian power law fluid over a semi-infinite non-isothermal stretching sheet with internal heat generation/ absorption. The flow is caused by linear stretching of a sheet from an impermeable wall. Thermal conductivity is assumed to vary linearly with temperature. The intricate coupled non-linear boundary value problem has been solved by a combination of Keller box method and shooting technique. An important observation of our study is that the velocity boundary layer thickness and thermal boundary layer thickness decreases with the increase of power law index in the presence / absence of variable thermal conductivity.

Competitiveness is a driving force behind the revolution of global business. Total quality management (TQM), total productive maintenance (TPM), six sigma, business process reengineering (BPR), lean, International Organisation for Standardization (ISO) series of standards and so on are most popular initiatives employed by the manufacturing organizations as Organizational Performance Improvement Techniques. All these approaches are generated in developed countries and have different orientations. Similarities, differences and interrelationship among these techniques in terms of objectives concept, methodologies and scope have remained confusing to the industry. Similarly, selection of one of these or combination of several of these techniques has remained a problematic issue in industry. All approaches are useful but to be treated with caution. Each has its strength and weakness and also in some cases a certain amount of overlap. This paper reviews in brief the theoretical aspect of TQM, TPM, Six Sigma, BPR, Lean and ISO series of standards which highlights similarity, differences and potentiality of these approaches to improve organizational performance.

Fly ash is a waste produced from thermal power stations, which contributes to environmental pollution. A number of studies have been conducted to investigate the influence of randomly oriented fibers on the strength behavior of coarse grained and fine grained soils. The effect of fiber inclusion on the strength characteristics of soil fly ash mixtures has not been reported so as much detail as in the case of the soils. In present study, polypropylene fibers were mixed with various proportions of soil fly ash mixtures to investigate the relative strength gain in the terms of unconfined compression strength (UCS). Samples of soil fly ash mixtures were tested in unconfined compression with 0, 0.5, 1.0 and 1.5 per cent polypropylene fibers. The results presented show that the UCS increases with the increase in the per cent of fibers for all the proportions of soil fly ash mixtures under consideration. Samples of soil and soil fly ash showed significant higher increase in UCS and residual strength compared to the samples of the fly ash. Results are, also, presented to show that the addition of polypropylene fibers increase the residual strength of soil fly ash mixture significantly more than the increase in the UCS.

In this paper, we have investigated the inductive inference of complex grammar of subset of Marathi (Indian) language and results are reported. We have investigated Elman recurrent networks (ERNs), Jordon recurrent networks (JRNs), time lagged recurrent networks (TLRNs) and recurrent neural networks (RNNs). In this empirical study, we consider the task of classifying Marathi language sentences as grammatical or ungrammatical as well as modeled the problem as a prediction problem. We have also analyzed the operation of the networks by investing rule approximation.

In this paper an image fusion technique is developed to remove clouds from satellite images. The proposed method involves an auto associative neural network based PCAT (principal component transform) and SWT (stationary wavelet transform) to remove clouds recursively which integrates complementary information to form a composite image from multitemporal images. Some evaluation measures are suggested and applied to compare our method with those of covariance based PCAT fusion method and WT-based one. The PSNR and the correlation coefficient value indicate that the performance of the proposed method is better than others. It also enhances the visual effect.

Limits to precision impose limits to the complexity of analog circuits, hence fuzzy analog controllers are usually oriented to fast low-power systems with low medium complexity. This paper presents a strategy to preserve most of the advantages of an analog implementation, while allowing a marked increment in system complexity. A digitally-programmable analogue fuzzy logic controller (FLC) is presented. Input and output signals are processed in the analog domain whereas the parameters of the controller are stored in a built-in digital memory. Design emphasis has been placed on consequents and defuzzifiers. The singleton or zero-order Sugenopsilas method is chosen since it offers a good trade off between simplicity and accuracy. The circuits have been simulated using Tanner tools.

The present paper illustrates study on feasibility of ANN modeling for road traffic noise prediction at Indian Intermediate, Yavatmal city, district place of Vidarbha region in Maharashtra state. Sixteen locations were identified at uninterrupted and interrupted traffic flow conditions for conducting field studies Traffic volume study (composition & classified traffic volume) and noise level study are carried out simultaneously. Artificial neural network software (Elite ANN) is used, the network uses feed forward negative back propagation algorithm with three hidden and three previous time elements of weights (Pandharipande & Badhe, 2002). ANN modeling is performed through input data as- Total traffic, Traffic composition (bus/truck, LCV, TW, bicycle and others) in % and carriageway width, Distance of receiver from pavement. Output is estimated as L10, Leq, LNP, TNI and NC. The observed input and output data is processed and trained through ANN for interrupted and uninterrupted flow condition. To enhance the accuracy of prediction, further this model has been tested by using linear regression analysis between observed and predicted noise levels. In the present case, it is observed that there is no significant difference between the observed and predicted noise levels, indicating the accuracy of model.

Session setup time is a critical factor for multimedia applications. Some of the factors that affect the session setup delay are length of SIP messages, bandwidth and packet loss in wireless link This paper aims at reducing the session setup delay in UMTS IP Multimedia Subsystem. We propose compression of SIP header by Text-based Compression using Cache and Blank (TCCB) approach and a caching scheme. In caching scheme, during registration, the address of serving call session control function (S-CSCF) of mobile users are cached at Interrogating-CSCF (I-CSCF). Typically, it takes 300 ms to find the address of called mobile user's Serving CSCF and it can be minimized using cache. A simulation has been carried out to analyze the effect of SIP header compression and caching scheme. The result shows that for 9.6 Kbps channel, a reduction of 25% is possible and for 19.2 Kbps channel 19% reduction can be achieved.

Location of shunt compensation devices is important for the enhancement of the voltage stability for practical power systems. This paper presents a comparison of several voltage stability indices in electric power system to identify the weakest bus/ area of the system. Shunt FACTS controller is introduced at the weakest bus in IEEE 14-bus test system and its effectiveness is assessed by comparing voltage profile and loading margin enhancement. Various line stability indices are also compared with and without shunt FACTS controller. It is shown that the best location for reactive power compensation for improving static voltage stability margin is the "weakest bus" of the system.
