There has been a growing interest among the researchers in the area of soft computing assisted material modeling in general and modeling of concrete in particular. Their results look very promising. Concrete is a heterogeneous material with complex behavior and is not amenable for crisp mathematical predications. Most of the inferences regarding the material behavior are formulized after going through experimental results that consists of equipment imprecision, tolerances and human factor. The analytical modeling of concrete using traditional methods is arduous and not robust. Further, the mathematical models developed using traditional statistical methods are generally based on assumed relationships and do not have the true predicting capability outside the experimental domain used for their development. Unlike traditional parametric methods, the soft computing methods do not assume a relationship between various parameters and concrete performance. The relationship is rather generated from the experimental data provided to build and train the model. This paper makes a modest attempt to present an elaborative discussion on the applications of soft computing techniques in concrete technology and their advantages. The published research work pertaining to applications of constituents of soft computing in general and hybrid systems in particular are discussed. The paper concludes with a briefing on the contribution of authors in this area. Copyright © 2007 IICAI.

Adverse drug reaction (ADR) may cost a lot of unnecessary medical resources and leads to extra suffering on patients. To provide the prompt information about ADR and avoid the rate of occurrence of ADR is an important task yet to be done. The US Food and Drug Administration (FDA) provides a Adverse Event Reporting System (AERS) which contains a lot of clinical reports about ADRs. However, the biologists still do not know precisely which observed events are directly caused by drug-drug interactions. We use the probability analysis method to find the associations between a set of drugs and the symptoms for predicting the ADR and apply the decision tree to discovery the association rules between the drug-drug interactions and symptoms. ©2007 IEEE.

Microarray is widely used for the cancer research and identifies different expressions for specific genes. We present a computational method for constructing cancer and normal gene regulatory networks from micorarray data based on transcription factor analysis and independency test. The web service technology is used to wrap the bioinformatics toolkits of methods and databases to automatically extract the promoter regions of DNA sequences and predict the transcription factors that regulate gene expressions. After reconstructing the gene regulatory network, the network statistical measure and network motifs extract the potential genes to compare the sub-networks between the cancer and normal gene networks. We adopt the microarray datasets from Stanford Microarray Database of prostate cancer as a target application to evaluate the methods. ©2007 IEEE.

Nosocomial infections or hospital acquired infections are diseases that develop during an admission to hospital and are a consequence of treatment, procedures of treatment or work of hospital staff. These infections are dangerous because they are caused by bacteria that are developed and transmitted within the hospital, where they may reach a high level of resistance to antibiotics. The goal of this study is to identify such infections for a single patient or hospital units and to create a real time information system for analyzing the microbiological data and to control the infections. In order to attain this objective, we introduce a knowledge based system approach for microbiological investigation to select the most suitable antibiotic therapy. The knowledge base of the proposed system has been obtained from international standard guidelines for microbiological laboratory practice, from experts' suggestions. Also we present the overall structure of the system and its implementation. This system will help medical practitioners and physicians to adopt appropriate methodology for controlling nosocomial infections. © 2007 Asian Network for Scientific Information.

This paper is concerned with the problem of estimating the motion of a single camera from a sequence of images, with an application scenario of vehicle egomotion estimation. Egomotion estimation has been an active area of research for many years and various solutions to the problem have been proposed. Many methods rely on optical flow or local image features to establish the spatial relationship between two images. A new method of egomotion estimation is presented which makes use of the Fourier-Mellin Transform for registering images in a video sequence, from which the rotation and translation of the camera motion can be estimated. The Fourier-Mellin Transform provides an accurate and efficient way of computing the camera motion parameters. It is a global method that takes the contributions from all pixels into account. The performance of the proposed approach is compared to two variants of optical flow methods and results are presented for a real-world video sequence taken from a moving vehicle. ©2007 IEEE.

A Wireless Sensor Network (WSN) consists of a large number of randomly deployed sensor nodes. These sensor nodes organize themselves into a cooperative network and perform the three basic functions of sensing, computations and *** paper proposes a flat-routing technique for such a network consisting of homogenous nodes. It is an energy-efficient data gathering protocol where sensor nodes in the network form an Antchain. The role of Antchain head and Antchain tail for each data gathering process is scheduled by means of a Time Division Multiple Access technique which ensures uniform depletion of energy among sensor nodes. The real advantage comes to light in the event of the death of a node. The proposed algorithm heals the network in such a way that only one node communicates with the base station at the end of the data gathering process. Simulation results indicate that Self-Healing AntChain performs better than other AntChain systems in terms of network lifetime, average energy consumed and aggregated data delivery ratio, in addition to being a highly fault-tolerant, flexible and adaptive system.

The performance of any OCR system heavily depends upon printing quality of the input document. Many OCRs have been designed which correctly identify fine printed documents both in Indian and foreign scripts. But little reported work has been found on the recognition of the degraded documents. The performance of standard machine printed OCR system working for fine printed documents decreases, if it is tested on degraded documents. The degradation in any document can be of many types. In this paper, we have identified different kinds of degradation available in printed Gurmukhi script. After identifying the different kinds of degradation, problems associated with each kind of degradation have been discussed; some possible solutions have also been discussed. This paper is extremely useful for researchers engaged in recognizing the degraded documents in any script, because same kinds of degradation can be found in most of the scripts of the world

The steganography is the embedding of secret message in the cover image for covert communication. In this paper we present a high capacity data embedding using colour palette decomposition (CPD) in which the payload is embedded into the cover image as an index of shifted centroids which is derived from the clustering of the cover image to derive the stego image. The error control coding is applied to stego image to increase PSNR, capacity and security. It is observed that our algorithm has higher PSNR and capacity in comparison to earlier works

2007 IET-UK International Conference on Information and Communication Technology in Electrical sciences (ICTES 2007)

作者： Suraiya Tarannum S. Srividya D. S. Asha R. Padmini L. Nalini K. R. Venugopal L. M. Patnaik Department of Computer Science and Engineering University of Visvesvaraya College of Engineering Bangalore University Bangalore India Microprocessor Applications Laboratory Indian Institute of Science Bangalore India

Effective utilization of limited power resources by the sensors is pre-eminent to the wireless sensor networks. Organizing the network into balanced clusters based on assigning equal number of sensors to each cluster may have the consequence of unbalanced load on the cluster heads. By-product of this is unbalanced consumption of the energy by the nodes which leads to minimization of network lifetime. We put forth a Sink administered load balanced dynamic hierarchical protocol (SLDHP) to balance the load on the principal nodes. Hierarchical layout of the sensors endows the network with increased lifespan. Outcome of this protocol also includes substantial saving of the energy consumed by the nodes. Simulation results indicate a significant improvement of performance over base station controlled dynamic clustering protocol (BCDCP).
