In this paper, we study the convergence rates of homogenization problems for composites with general stratified periodic structure. After introduced auxiliary function, we get the representation formula satisfied by oscillatory solution and homogenized solution. Then we utilize the formula in combination with the asymptotic estimates of Green functions to obtain convergence rates in p L of solu...

There are many sources of error in counting votes: the apparent winner might not be the rightful winner. Hand tallies of the votes in a random sample of precincts can be used to test the hypothesis that a full manual recount would find a different outcome. This paper develops a conservative sequential test based on the vote-counting errors found in a hand tally of a simple or stratified random ...

We investigate the space of ordinal semantics, where the status of an argument is interpreted by a natural number. In doing so we do not only consider the usual acceptability-based approach for generalizing classical semantics to multivalued semantics, i. e., positioning “undecided” arguments to be in between “in” and “out” arguments, but also a controversiality-based approach where we interpre...

This descriptive survey research was undertaken to study the factors affecting attitudes of agricultural faculty members towards nanotechnology. The statistical population of this study consisted of the agricultural faculty members in Iran (N=225). A sample of 144 persons was selected by using the stratified random sampling method. Data collected using a mailed questionnaire that was validated ...

Using a proportionate stratified sample of 300 titled and non-titled respondents this study was conducted to tap into their attitudes, beliefs, and perceptions of the proliferation of title taking in Igboland. Major questions of interest included: “who are traditional title holders?” “Why do individuals seek titles?” “Why do chiefs award such titles? “Should titles be given to ‘diaspora’ Igbos ...

The First Part of this paper deals with the study of the precision of an unbiased estimator of a population income inequality index in the stratified samplings with and without replacement. In this Second Part, we first analyze the asymptotic distribution of the sample income inequality index. Then, we establish different criteria to select the suitable sample size to estimate the population in...

To what extent do friendship ties influence the conversation structure in open groups? Openly accessible Facebook groups offer the opportunity to examine how individuals leverage their existing friendship relations when speaking to a large and often heterogeneous audience. For example, those with many friends in the group may receive more positive signals from others and also may have their con...

We present an algorithm which, given a deformation with section of a reduced plane curve singularity, computes equations for the equisingularity stratum (that is, the μ-constant stratum in characteristic 0) in the parameter space of the deformation. The algorithm works for any, not necessarily reduced, parameter space and for algebroid curve singularities C defined over an algebraically closed ...

Several northeast-trending transverse faults cut the Purcell succession and parts of the Lower Paleozoic succession in the Hughes Range. Relationships along unconfonnities within and at the base of the Lower Paleozoic strata provide evidence of the natilre and timing of displacement on these faults. Field mapping of the faults and unconformities hounding three Lower Paleozoic formntions have be...

Researchers have highlighted that the main factors that contribute to IT service failure are the people, process and technology. However, relatively few empirical studies examine to what degree these factors contribute to service disruptions in the public sector organizations. This study explores the IT service management (ITSM) at eight (8) Front-end Agencies, four (4) Ministries and six (6) D...
