cepstral coeffients (MFCCs) based speech features. In the case of closed-set ASI, the identity (Id) of the unknown speaker is assigned to the Id of that reference speaker to whom the number of MFCCs pair having same distributions is maxima with 88.26% accuracy at 8% level of significance. In open-set ASI, after determining the identity of the unknown speaker it is verified whether the unknown s...

Abstract This paper investigates the performance of several meta-heuristic algorithms, including Particle Swarm Optimisation (PSO), different variants Differential Evolution (DE), Biogeography-Based (BBO), Cultural Algorithm (CA), Optics-Inspired (OIO), and League Championship (LCA), for optimum layup laminated composite plates. The study provides detailed Pseudo codes algorithms. buckling capa...

The methods measuring the departure between observation and the model were reviewed. The following statistics were applied on two experimental data sets: ChiSquared, Kolmogorov-Smirnov, Anderson-Darling, Wilks-Shapiro, and Jarque-Bera. Both investigated sets proved not to be normal distributed. The Grubbs’ test identified one outlier and after its removal the normality of the set of 205 chemica...

In this paper we show how the Färe, Grosskopf and Lovell (1985) input congestion nonparametric test can be performed to reach a statistical conclusion. To achieve this goal, we use Simar and Wilson (1998, 2000) radial distance functions bootstrap technique. An empirical illustration on airports congestion is provided. The results show that the technology is globally congested and that nine of t...

This paper introduces the two-sample Anderson-Darling (AD) test of goodness of fit as a tool for comparing distributions, response time distributions in particular. We discuss the problematic use of pooling response times across participants, and alternative tests of distributions, the most common being the Kolmogorov-Smirnoff (KS) test. We compare the KS test and the AD test, presenting conclu...

We present an updated analysis of the solar neutrino problem in terms of both Mikheyev-Smirnov-Wolfenstein (MSW) and vacuum neutrino oscillations , with the inclusion of the preliminary data collected by the Su-perKamiokande experiment during 306.3 days of operation. In particular, the observed energy spectrum of the recoil electrons from 8 B neutrino scattering is discussed in detail and is us...

Relative Age Effect (RAE) is the breakdown by both age grouping and dates of birth of athletes. In the past 20 years the existence of this effect has been shown with higher or smaller impact in multiple sports, including soccer. The purpose of this study was to identify the existence of RAE in European soccer players. The sample included 841 elite soccer players who were participants in the UEF...

SUMMARY Interval censored data arise naturally in large-scale panel studies where subjects can only be followed periodically and the event of interest can only be observed between some time intervals. To estimate the survival function the nonparametric maximum likelihood estimator (NPMLE) is commonly used, which is a step function having some large jumps. But in many applications the underlying...
