SUMMARY Larger object classes often become more costly classes in the maintenance phase of object-oriented software. Consequently class would have to be constructed in a medium or small size. In order to discuss such desirable size, this paper proposes a simple method for predictively discriminating costly classes in version-upgrades, using a class size(More)
Generalized inverses have many applications in engineering problems, such as data analysis, electrical networks, character recognitions, and so on. The most frequently used generalized inverse is a Moore-Penrose type's one. Let <i>A</i> be <i>m</i> x <i>n</i> matrix. The Moore-Penrose generalized inverse of <i>A,</i> i.e., <i>n</i> x <i>m</i> matrix(More)

The HI:tFA has been already applied to data smoothing, integral of function and Cauchy principal value integral[4, 6]. Here we(More)
We present a hybrid integral to obtain symbolic results of an indefinite integral where the integrand is an univariate rational function whose coeficients have a parameter. We consider calculating power series roots of the denominator polynomial by applying Hensel construction. Accurate numerical results for a definite integral are easily obtained by simple(More)
The problem of solving approximate GCD of multivariate polyno-mials has been well studied in the computational literature because of its importance particularly in engineering application[2, 6, 7]. Numbers of algorithms have been proposed to give the approach such as approximate subresultant PRS and modular algorithm using SVD. Here we focus on EZ-GCD[3],(More)
Lupin [1] is an ongoing research subject in Ehime University that aims at: • Establishing a Web-based mechanism and framework that allows easy and systematic creation and construction of computational Problem Solving Environments (PSEs), • Exploiting the standard Web technologies to support the infrastructure, • Implementing a prototype to demonstrate the(More)
