Article Citation - WoS: 19Citation - Scopus: 27Obtaining Routh-Pade Approximants Using the Luus-Jaakola Algorithm(inst Engineering Technology-iet, 2005) Singh, VThe Routh-Pade approximation problem relating to the construction of a stable reduced-order (rth-order) approximant G(r)(s) for a given stable high-order (nth-order) transfer function G(s), so as to fully retain the first r time moments/Markov parameters of G(s) as well as to minimise the errors between a few subsequent time moments/Markov parameters of G(s) and those of G(r)(s), is revisited. For the solution of this problem, a novel computer-aided method based on the well known Luus-Jaakola algorithm is proposed.Article Citation - WoS: 2Citation - Scopus: 2Global Robust Stability of Interval Delayed Neural Networks(inst Engineering Technology-iet, 2009) Singh, V.; Sıngh, Vımal; Sıngh, Vımal; Department of Mechatronics Engineering; Department of Mechatronics EngineeringIn recent years, the problem of global robust stability of Hopfield-type interval delayed neural networks has received considerable attention. A number of criteria for the global robust stability of such networks have been reported in the literature. On the basis of the idea of dividing (in respect of both the connection weight matrix A and the delayed connection weight matrix B) the given interval into two intervals, four new criteria for the global robust stability of such networks are established. The criteria are in the form of linear matrix inequality and, hence, computationally tractable. The criteria yield a less conservative condition compared with many recently reported criteria, as is demonstrated with an example.Editorial Citation - WoS: 2Citation - Scopus: 2Robust Stability of Cellular Neural Networks With Delay: Linear Matrix Inequality Approach - Reply(inst Engineering Technology-iet, 2007) Singh, V.[No Abstract Available]Article Citation - WoS: 20Citation - Scopus: 25Framework for Evaluation and Validation of Software Complexity Measures(inst Engineering Technology-iet, 2012) Misra, S.; Akman, I.; Colomo-Palacios, R.This study proposes a framework for the evaluation and validation of software complexity measure. This framework is designed to analyse whether or not software metric qualifies as a measure from different perspectives. Unlike existing frameworks, it takes into account the practical usefulness of the measure and includes all the factors that are important for theoretical and empirical validation including measurement theory. The applicability of the framework is tested by using cognitive functional size measure. The testing process shows that in the same manner the proposed framework can be applied to any software measure. A comparative study with other frameworks has also been performed. The results reflect that the present framework is a better representation of most of the parameters that are required to evaluate and validate a new complexity measure.Article Citation - WoS: 7Citation - Scopus: 10Efficient Software Review Process for Small and Medium Enterprises(inst Engineering Technology-iet, 2007) Mishra, D.; Mishra, A.A considerable amount of software is produced world-wide by small and medium enterprises (SMEs). These organisations do not have enough resources to implement a rigorous quality plan. It has been established that reviews of various artifacts play a very important role in ensuring the quality of software. Traditional review methods are rigorous and their implementation is cumbersome for SMEs. A new review process which is easy to implement and requires almost no documentation is introduced. It is based on reviewers' efforts to produce high-quality software while minimising the inspection cost. Additionally, people who are conducting this review need not be present at the same place during most phases of the review process. This process has been successfully implemented in a CMM level 3 software development company intending to achieve CMMI level 5 and results are found to be quite encouraging.Article Citation - WoS: 14Citation - Scopus: 18Optimal Routh Approximants Through Integral Squared Error Minimisation: Computer-Aided Approach(inst Engineering Technology-iet, 2004) Singh, V; Chandra, D; Kar, HA computer-aided method for obtaining a reduced-order approximant of a given (stable) single-input single-output system based on the minimisation of integral squared error (ISE) pertaining to a unit-step input is presented. Both the numerator and denominator coefficients of the model are treated as free parameters in the process of optimisation. The method has a built-in stability-preserving feature. The problem of formulating the ISE is circumvented by introducing a set of equality constraints.Article Citation - WoS: 3Citation - Scopus: 5Equivalent Forms of Single-Operational Transconductance Amplifier Rc Oscillators With Application To Grounded-Capacitor Oscillators(inst Engineering Technology-iet, 2010) Singh, V.It is shown that, given a single-operational transconductance amplifier (OTA) resistor-capacitor (RC) sinusoidal oscillator circuit, it can be put in three other, structurally distinct forms without altering its characteristic equation. This result may facilitate the transformation of some of the available single-OTA RC oscillators employing floating capacitors into the desirable form of employing grounded capacitors. The result turns out to be an aid to a Boolean circuit synthesis method previously given by Tao and Fidler for the generation of single-OTA RC oscillators.Article Citation - WoS: 29Citation - Scopus: 37Metrics Suite for Maintainability of Extensible Markup Language Web Services(inst Engineering Technology-iet, 2011) Baski, D.; Misra, S.The eXtensible Markup Language (XML) web services are emerging as the de-facto mechanism for exchanging structured information between applications. The large popularity and acceptance of web services led the developers to adopt the best practices of web service implementation and to find the ways for managing and maintaining web services more effectively. Maintainability, one of the important factors, which affects the quality of XML web services, can be controlled by the proper software metrics that are specifically designed and developed for it. In this paper, we present a suite of metrics to evaluate the quality of the XML web service in terms of its maintainability. The present suite of metrics includes: data weight of a web service description language, distinct message ratio metric, message entropy metric and message repetition scale metric. All the proposed metrics have been evaluated theoretically and validated empirically. A comparative study with similar measures proves the worth of the metric suite.Article Citation - WoS: 4Citation - Scopus: 5Improved Global Robust Stability Criterion for Interval Delayed Neural Networks(inst Engineering Technology-iet, 2009) Singh, V.A novel criterion for the global robust stability of Hopfield-type interval neural networks with delay is presented. Some existing criteria turn out to be special cases of the present criterion. An example shows the effectiveness of the present criterion.
