To produce near-native American English (AE) vowels, Japanese speakers must extend their five vowel system with at least six new vowels. Three experiments have been conducted to acquire both perceptual and acoustic measures about Japanese accented English (JE)vowels. Six non-back vowels of AE in several phonetic environments were recorded from four Japanese male talkers with moderate English sk...

In the last couple of years, there has been renewed interest in systematic methods for the construction of Prolog programs, for example (Gegg-Harrison, 1995), (Kirschenbaum et al., 1996), (Sterling and Yalçinalp, 1996), and (Vasconcelos and Fuchs, 1995). This paper loosely characterises the progression of approaches that have been offered for systematic construction of logic (usually Prolog) pr...

The selection of an optimal regression model comprising linear combinations of various integer powers of an independent variable (explanatory variables) is considered. The optimal model is defined as the most accurate (minimal variance) stable model, where all parameter estimates of the orthogonalized explanatory variables are significantly different from zero. The potential causes that limit t...

ePCMM (e-Learning Process Capability Maturity Model) is used for evaluating the capability and maturity of an institution engaged in e-Learning based on e-Learning key process areas. It is a stepwise process improvement which can be implemented by both staged model and continues model.

We discuss a nested collection of three superclasses of perfect graphs: near-perfect, rank-perfect, and weakly rank-perfect graphs. For that we start with the description of the stable set polytope for perfect graphs and allow stepwise more general facets for the stable set polytopes of the graphs in each superclass. Membership in those three classes indicates how far a graph is away from being...

The rate constants and secondary deuterium Isotope ef'fects are measured in the solvo'lysis of various allyHc p-nitrobenzoates. The obtained results are explained by differences in inductive effects o>f vardous groups in the side-chain. These results are in keeping with the stepwise mechanism according to which neighboiring group nand n-paxticiipation is not revealed in the studied solvCJ!lytic...

We examine a corpus of physics tutorial dialogues between a computer tutor and students. Either graphs or illustrations were displayed during the dialogues. In this work, stepwise linear regression, augmented to remove unwanted terms, is used to build models that identify situations when each graphic may aid learning. Our experimental results show that grouping students by pretest score, then b...

abstract the present study was aimed to investigate the planting dates effects on yield associated traits and also determining stability of the result of factor analysis and stepwise regression analysis in different planting dates of rapeseed genotypes at biekol agriculture research station during 2011-12 cropping season. result of split plot analysis exhibited significant genotypes effects for...

In this paper, we formalize two stepwise approaches, based on pseudo-random generators, for proving P 6= NP and its arithmetic analog: Permanent requires superpolynomial sized arithmetic circuits.
