Feature selection has become very vital aspect in musical instruments sounds for handling the problem of 'curse of dimensionality'. Various feature selection techniques have been applied in this domain focusing on Western musical instruments sounds. However, study on feature selection using rough sets of non-Western musical instruments sounds including Malay Traditional musical instruments is inadequate and still needs an intensive research. Thus, in this paper, an alternative feature selection technique using rough set theory based on Maximum Degree of dependency of Attributes (MDA) technique for Traditional Malay musical instruments sounds is proposed. The modeling process comprises eight phases: data acquisition, sound editing, data representation, feature extraction, data discretization, data cleansing, feature selection using proposed technique and feature validation via classification. The results show that the performance of the best 17 selected features is increase up to 99.82% and 98.03% with 1-NN and PART classifiers respectively. © Springer-Verlag (2010).

Test Oracle is a mechanism to determine if an application executed correctly. In addition, it may be difficult to verify logical software modules due to the complexity of their structures. In this paper, an attempt has been made to study the applications of Artificial Neural Networks as Single-Network Oracles to verify logical modules. First, the logical module under test was modeled by the neural network using a training dataset generated based on the software specifications. Next, the proposed approach was applied to test a subject-registration application;meanwhile, the quality of the proposed oracle is measured by assessing its accuracy, precision, misclassification error and practicality in practice, using mutation testing by implementing two different versions of the case study: a Golden Version and a Mutated Version. The results indicate that neural networks may be reliable and applicative as oracles to verify logical modules. © 2010 IEEE.

Decision-making structures are important building blocks in most of the software;however, it may be difficult to verify them because there are various input conditions and several paths causing them to behave differently. Test oracles are reliable sources of how the software must operate. The aim of the present paper is to study the applications of Artificial Neural Networks as an automated oracle to test decision-making structures. First, the decision rules were modeled by the neural network using a training dataset generated based on the software specifications and domain expert knowledge. Next, after the neural network was applied to test a subject-registration application, the proposed approach was evaluated using mutation testing. The accuracy of the resulted oracle is discussed as well. © 2010 IEEE.

Pin number or password that is used for authentication can be easily attacked. This limitation triggered the utilization of biometric for secured transactions. Biometric is unique to each individual and is reliable. Among the types of biometric being used currently, iris is the most accurate and it remains stable throughout a person's life. However the major challenge on iris and other biometric for authentication is the intra user variability in the acquired identifiers. Iris of the same person captured at different time may differ due to the signal noise of the iris camera. Traditional cryptography method is unable to encrypt and store biometric template, then perform the matching directly. Minor changes in the bits of the feature set extracted from the iris may lead to a huge difference in the results of the encrypted feature. In our approach, an iris biometric template is secured using iris biometric and passwords. Error Correction Code, ECC is introduced to reduce the variability and noise of the iris data. Experimental results show that this approach can assure a higher security with a low false rejection or false acceptance rate. The successful iris recognition rate using this approach is up to 97%. © 2010 IEEE.

In this paper, a method for assessment of the ovarian follicle growth is presented. 3D ultrasound volumes of ovaries are processed. Ovarian follicles are shown as hypoechogenic areas in the cross-section images. In first phase, global translations and rotations of two observed follicle constellations from two consecutive ovary examinations are detected. In second phase, detailed local deformations are estimated using elastic registration. The proposed method has been tested using artificial simulated models of ultrasound images of ovaries. Preliminary results shows the proposed method is efficient and reliably detects deformations ovarian follicles cause by their growth.

In recent years, the uses of intelligent methods in biomedical studies are growing gradually. In this paper, a novel method for diabetes disease diagnosis using modified spline smooth support vector machine (MS-SSVM) is presented. To obtain optimal accuracy results, we used Uniform Design method for selection parameter. The performance of the method is evaluated using 10-fold cross validation accuracy, confusion matrix, sensitivity and specificity. The comparison with previous spline SSVM in diabetes disease diagnosis also was given. The obtained classification accuracy using 10-fold cross validation is 96.58%. The results of this study showed that the modified spline SSVM was effective to detect diabetes disease diagnosis and this is very promising result compared to the previously reported results. © 2010 Springer-Verlag Berlin Heidelberg.

This paper reports on the outcomes of evaluation recently conducted on Small Medium Enterprises (SME) in Malaysia with respect to a newly developed software Process Improvement model called iSPA. It is conducted based on identified critical success factors for a software project to be successful. Initially, the evaluation investigates on the core process and best practices for a software project management and implementation. It also looks at the feasibility and acceptability of software companies to achieve this model and ended up with a tool development. The evaluation findings indicate the acceptance towards a new SPI methodology and relevance of the prototype tool to mitigate and assist in SPI implementation in an organization.

Nowadays, Tension or Stress is a common and serious problem in our Global Village. Stress and stress related factors contribute to tension and reduced ability to handle life's everyday challenges. This paper proposes a new method to reduce the stress and tension of our life and also proves that mentally, spiritually and physically relaxation can be achieved by the recitation of the holy Quran. In this technique of listening, reading and watching the text of the Holy Quran subject (User) can involve the whole body. The entire process will be controlled by brain, as a result during this practice the whole body will receive relaxation/refreshment, and the exhaustion, boring and tiredness will be finished. This physiological biofeedback manner provides groceries for spirit. Hence this means can be used in hospitals for mentally disturb and depression effected patients, for relaxation of the soldiers, for refreshing the students, to cool down workers in industries and for the entertainment of passengers in buses and airplanes. This approach replaces negative thoughts with positive and truthful thoughts. © 2010 IEEE.

In many cases, students become stressed and they become worried about their study, which in terms become a great impediment to their learning capability. This paper proposes new framework of intelligent game model based on biofeedback techniques. The model consists of two modules (visual learning and IQ test) that will conjoined with a biofeedback device connected to a computer to monitor student heart rate and record its changes in a stressful situation and generate appropriate reports. The two games have different purpose to serve. Visual learning games will improve learner's visual learning capability, memorizing capability and IQ test will improve analytical ability. © 2010 IEEE.
