In this paper, several simple and efficient sign based normalized adaptive filters, which are computationally superior having multiplier free weight update loops are used for cancelation of noise in electrocardiographic (ECG) signals. The proposed implementation is suitable for applications such as biotelemetry, where large signal to noise ratios with less computational complexity are required. These schemes mostly employ simple addition, shift operations and achieve considerable speed up over the other least mean square (LMS) based realizations. Simulation studies shows that the proposed realization gives better performance compared to existing realizations in terms of signal to noise ratio and computational complexity. © 2010 Elsevier B.V.

6-Amino-5-cyano-4-aryl/heteroaryl-1,4-dihydropyrano[2,3-c]pyrazoles 5(a-h) were synthesized from arylidine malononitrile/arylidine ethylcyanoacetate 3(a-h) which were synthesized by the reaction of aromatic aldehydes and malononitrile, using L-proline as a catalyst in aqueous media. The reaction has the advantages of good yield, easy separation and of being environment friendly. The structures of newly synthesized compounds have been established by spectral analysis and evaluated for their anti-inflammatory, antibacterial, and antifungal activity. Source

Mobile ad hoc networks (MANETs) have distinct features: like dynamic nodes, changing topologies, nodes cooperation and open communication media. Anonymity of message contents and participants is the most concerned task in MANET communication. Most of the existing methods face a challenge due to heavy cryptographic computation with high communication overheads. In this paper we propose an unconditionally secure privacy preserving message authentication scheme (PPMAS), which uses Modified New variant ElGamal signature Scheme (MNES). This scheme enables a sender to transmit messages, providing authentication along with anonymity, without relying on any trusted third parties. It also allows the untraceability of the link between the identifier of a node and its location. The experimental analysis of the proposed system is presented. Source

The core aim of the research is to measure and analyze the quality of services offered by the top three public- and private-sector banks in India and to attempt to know how bank services quality affects customer satisfaction. By administering both questionnaires and personal interviews, researchers garnered the opinions of a total of 600 respondents with BANKQUAL statement. The authors applied Cronbach’s alpha to test reliability and the selected hypotheses have been proven with Chi-square tests and t-tests. All the public-sector banks chosen for the study lead in the satisfaction index over the private-sector banks by demonstrating differences in the dimensions of credibility, influence, and geographic spread. The research is most precious to diverse stakeholders of the Indian banking industry, particularly to banks who want to know about their existing service quality for further improvement. For the first time, the researchers introduced the comprehensive BANKQUAL statement to test out the quality of bank services in India. © 2016, Copyright © Taylor & Francis Group, LLC. Source
