abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...
Thyme is an important medicinal plant in cosmetic, pharmaceutical and food industries. The first step for breeding of thyme is evaluating of genetic variation and relationship between thyme’s accessions. Therefore, the objective of this study was to evaluate morphology, chemical and molecular variation of 13 accessions of Thyme medicinal plant. ANOVA showed significant differences between acces...
Non-metric dissimilarity measures may arise in practice e.g. when objects represented by sensory measurements or by structural descriptions are compared. It is an open issue whether such non-metric measures should be corrected in some way to be metric or even Euclidean. The reason for such corrections is the fact that pairwise metric distances are interpreted in metric spaces, while Euclidean d...
The classical evidence theory can result in paradox in the process of information fusion. To resolve this problem, a multi-source data fusion method based on dissimilarity matrix and evidence theory is proposed. First, using the weighted Euclidean distance, evidence dissimilarity matrix is constructed. Second, dissimilarity between the evidences is measured. Third, using dissimilarity matrix, s...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
Given a set of objects V with a dissimilarity measure between pairs of objects in V , a PoCluster is a collection of sets P ⊂ powerset(V ) partially ordered by the ⊂ relation such that S ⊂ T iff the maximal dissimilarity among objects in S is less than the maximal dissimilarity among objects in T . PoClusters capture categorizations of objects that are not strictly hierarchical, such as those f...
Fast nearest neighbor (NN ) finding has been extensively studied. While some fast NN algorithms using metrics rely on the essential properties of metric spaces, the others using non-metric measures fail for large-size templates. However, in some applications with very large size templates, the best performance is achieved by NN methods based on the dissimilarity measures resulting in a special ...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Introduction: Inequity in access to health care facilities in one area could result in misdistribution of these resources. The aim of this study was to measure equity in distribution of physical and human resources in health sector among the cities of Loresta Province. Method: This survey is an analytical and descriptive study. Measuring inequity in distribution of resources and health care fa...
2 Abstract. Ecological studies have now gone beyond measures of species turnover towards measures of phylogenetic and functional dissimilarity. This change of perspective has a main objective: disentangling the processes that drive species distributions from local to broad scales. A fundamental difference between phylogenetic and functional analyses is that phylogeny is intrinsically dependent ...
