The reflectance factors of transparent fibers, free delustering agent, are predicted by geometric as well as Kubelka-Munk models. Transparent fibers are simulated by a net of glass capillary tubes containing different solutions of dyestuffs. Based on the results, prediction of the reflectance factor of capillary net by geometric model is relatively better than those obtained from Kubelka-Munk...

this study intended to develop a model describing speaking strategies for efl learners by taking into account the effects of learners’ gender and proficiency on the application of strategies. accordingly, this study was planned to have two main analyses, namely qualitative and quantitative. in this respect, 30 efl learners' viewpoints were sought, and then, based on the elicited responses, a 21...

Abstract Every day people see, describe, and remember motion events. However, the relation between multimodal encoding of events in speech gesture, memory is not yet fully understood. Moreover, whether language typology modulates this remains to be tested. This study investigates type event information (path or manner) mentioned gesture predicts which remembered varies across speakers typologic...

Speech communication is embedded in many daily activities. In this paper we investigate the effect of biking on respiratory and speech parameters. Breathing and speech production were recorded in eleven subjects while speaking alone and while speaking and biking with different rates. Breathing frequency, speaking rate, speech and pause intervals, overall intensity and f0 were analyzed for the d...

Research on multiword clusters (chunks) is based on the assumption that native speakers use plenty of chunks in their everyday language and they are considered as fluent speakers of language. Therefore the present study was an attempt to investigate the impact of using chunks on speaking fluency of Iranian EFL learners. In the first phase of the study, the students of two intermediate classes s...

Language classrooms are occasionally anxiety-breeding situations. Foreign language classroom anxiety which negatively affects foreign language learning is typically associated with productive activities mainly speaking skill. To cope with the issue and overcome language learning difficulties, the present study was conducted to explore the impact of mobile-assisted language learning on enhancing...

the main purpose of this paper is to present methods and recent development in the literature of intra industry trade (iit) measuring. the case study also is carried out for iranian manufacturing industries during time period 1997-2003. for this, iran's foreign trade data was collected, processed, and then used to estimate iit indices with respect to recent literature developments in iit m...
