Let N be the number of classes in a population to be estimated. Fix any preassigned error probability 0

A method of measuring three-dimensional spatial wave size is proposed and statistical distributions of the size characteristics are derived in explicit integral forms for Gaussian sea surfaces. New definitions of wave characteristics such as the crest-height, the length, the size and the wave front location are provided in fully dimensional context. The joint statistical distributions of these wav

This paper reports results of two experiments (phonetic production experiment and self-paced perception experiment) on what we call nuclear prominence in Japanese. The goal of this study is two-fold. First, through a production experiment (Experiment 1), we attempt to provide quantitative confirmation of the presence of nuclear prominence in Japanese, which has only been sporadically and informall

The purpose of this thesis is to examine how increased mobility of indigenous student migrants in Dhaka from the Chittagong Hill Tracts in Bangladesh affects notions of belonging and indigeneity. By applying a theoretical framework of mobility, global interconnectedness and lifestyle, the study challenges representations by indigenous rights advocates of indigenous people as inherently immobile an

In this paper we consider the asymptotic distributions of functionals of the sample covariance matrix and the sample mean vector obtained under the assumption that the matrix of observations has a matrix variate general skew normal distribution. The central limit theorem is derived for the product of the sample covariance matrix and the sample mean vector. Moreover, we consider the product of an i

In August 2015 a Swedish newspaper claimed that the Sweden Democrats were the largest political party in Sweden based on the results of single poll. We ask ourselves if this is a correct conclusion, considering the fact that the three largest parties in the poll were of roughly the same size. We analyse the parameter space and identify the subspace where the Sweden Democrats are the largest party.

This paper introduces means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variabi

Bodnar and Schmid (2008) derived the distribution of the global minimum variance portfolio weights and obtained the distribution of the test statistics for the general linear hypothesis. Their results are obtained in the case when the number of observations n is bigger or equal than the size of portfolio k. In the present paper, we extend the result by analyzing the portfolio weights in a small sa

The inverse of the standard estimate of covariance matrix is frequently used in the portfolio theory to estimate the optimal portfolio weights. For this problem, the distribution of the linear transformation of the inverse is needed. We obtain this distribution in the case when the sample size is smaller than the dimension, the underlying covariance matrix is singular, and the vectors of returns a

This paper describes the development of two test formats, COLLEX and COLLMATCH, measuring receptive recognition knowledge of English verb +NP collocations, and reports findings from pilots and initial test administrations involving Swedish upper-secondaryschool and university level learners. Administrations of the test formats produced highly reliable scores and the performance of native speakers

Abstract in UndeterminedThis study investigates the determinants of transfer of waste between the affected areas and other municipalities that resulted from the Great East Japan Earthquake. In particular, we investigate to what extent economic factors, but also social factors such as reciprocity and pro-social concerns, affect municipalities’ decision to accept disaster waste. We find some evidenc

The purpose of this thesis is to explore discourses of insecurity, vulnerability and conflict in Thailand’s Deep South. In order to understand how such discourses are shaped by gender ideologies, the study examines how ideas about men and women are articulated, reproduced and challenged in Thai civil society. Special attention is given to the ways in which men and masculinity are constructed withi
