In order to solve multiple constraints in the existing polygonal approximation algorithms of digital curves, a new algorithm is proposed in this article. Each control constraint is taken as the optimization objective respectively and the idea of multi-objective optimization is also applied. Vertex positions of the intermediate approximation polygon are represented by a binary sequence, and Hamm...

This paper tries to analyze the impacts of intermediate goods trade on production, consumption, investment, net exports, employment, labor wage and capital rent of Iran in its bilateral trade relations with China. This analysis has been done by modeling, solving and calibrating an international real business cycles (IRBC) model in period 1980-2009. The results show that when elasticity of subst...

The perceived prominence of three parts of speech (POS), nouns, verbs and adjectives, in three utterance positions, initial, intermediate and final, were examined in a perceptual experiment to see whether previously observed reductions in prominence of intermediate items were the result of positional effects or because words in this position belonged to the same POS, namely verbs. It was found ...

Test method facet is one of the factors which can have an influence on the test takers’ performance. The purpose of the current study was to investigate the effects of two different response types, multiple-choice cloze and multiple-choice test, on the pre-intermediate and intermediate test takers’ reading comprehension performance. To this end, 40 pre-intermediate and intermediate learners par...

The position in which seeds develop on the parental plant can have an effect on dormancy-break and germination. We tested the hypothesis that the proportion of seeds with intermediate physiological dormancy (PD) produced in the proximal position on a raceme of Isatis violascens plants is higher than that produced in the distal position, and further that this difference is related to temperature...

Comparative electrophysiological and histological studies were made on the functional significance of the secondary iris pigment migration for the sensitivity of the eye in the noctuid moth Cerapteryx graminis. The pigment position at different adapting light intensities was studied as well as the influence of different positions on the sensitivity of the eye. Adapting light intensities above a...
