Although luster potteries are frequently excavated at archeological sites in Iran, a thorough scientific study of their provenance has not yet been performed. In this work, 43 pieces of Iranian luster pottery (bowl, dish and tile) excavated from Rayy, Kashan, Maragheh, Alamoot, Takht-i-Sulayman and Jiroft were analyzed in order to investigate their origin. The luster shards which belong to Seljuks and Il-Khanids dynasties (12th–13th centuries) were analyzed using proton induced X-ray emission (PIXE) technique. To classify the fragments according to their location and origin, principal component analysis (PCA) and hierarchical cluster analysis (HCA) were applied to the chemical compositions of the body of the shards. We were able to classify the samples into three distinct groups using PIXE. 相似文献

Cadaver dissection stands as a crucial component in medical curricula around the world, although computer‐based multimedia programs have been introduced in order to replace the need for cadaver donations. Due to a decrease in the number of unclaimed bodies and rather few donations, there is an insufficient number of cadavers for anatomical studies in Iran. This study was carried out to evaluate medical students' awareness and willingness regarding body donation in Kashan University of Medical Sciences, Iran. In this study, a questionnaire was designed to focus on the cultural acceptability and personal willingness to donate one's body after death. Students from the university's anatomy classes (n = 331) participated in this study. Seventy‐seven percent of the students expressed their agreement toward the idea of utilizing body donation services, though only 25.4% of participants were willing to donate their own bodies. None of the demographic factors were associated with cultural acceptability or personal willingness towards body donation. These findings indicated that besides “payment”, other factors were associated with students' willingness to become donors. All factors of awareness except “previous awareness of organization” were associated with cultural acceptability. In this study, students suggested that encouraging people to register for body donation using mass media (25.6%) and teaching students to respect cadavers in the dissection environment (24.8%) were the best solutions for addressing the lack of cadavers. These findings indicated that a lack of awareness about body donation might be the main factor responsible for unwillingness towards body donation; therefore, improving the public's awareness and addressing the willingness of students regarding body donation may help overcome the current lack of donated cadavers.

The tracking problem of the fractional-order nonlinear systems is assessed by extending new event-triggered control designs. The considered dynamics are accompanied by the uncertain strict-feedback form, unknown actuator faults and unknown disturbances. By using the neural networks and the fault compensation method, two adaptive fault compensation event-triggered schemes are designed. Unlike the available control designs, two static and dynamic event-triggered strategies are proposed for the nonlinear fractional-order systems, in a sense that the minimum/average time-interval between two successive events can be prolonged in the dynamic event-triggered approach. Besides, it is proven that the Zeno phenomenon is strictly avoided. Finally, the simulation results prove the effectiveness of the presented control methods. 相似文献

The purpose of this study is to examine the impact of perceived brand orientation, intercultural friendship, and university reputation on international students’ course satisfaction and continuance behavioral intention towards the higher education in Malaysia. A total of 348 questionnaires, administered on international students, were collected to empirically test the research model using partial least squares path modeling approach, a structural equation modeling technique for the assessment of measurement and structural model. The empirical results imply that perceived brand orientation and university reputation positively influence course satisfaction and course continuance behavioral intention, while intercultural friendships influences course continuance intention but not course satisfaction. The implications and limitations of research are discussed in the following sections. 相似文献

Users of search engines express their needs as queries, typically consisting of a small number of terms. The resulting search engine query logs are valuable resources that can be used to predict how people interact with the search system. In this paper, we introduce two novel applications of query logs, in the context of distributed information retrieval. First, we use query log terms to guide sampling from uncooperative distributed collections. We show that while our sampling strategy is at least as efficient as current methods, it consistently performs better. Second, we propose and evaluate a pruning strategy that uses query log information to eliminate terms. Our experiments show that our proposed pruning method maintains the accuracy achieved by complete indexes, while decreasing the index size by up to 60%. While such pruning may not always be desirable in practice, it provides a useful benchmark against which other pruning strategies can be measured. 相似文献

This study investigates some of the differences and similarities between Kurdish-Persian bilinguals and Persian monolinguals with respect to the use of referring expressions in spoken narratives. The narratives were elicited from 36 participants, consisting of 24 bilinguals （Groups l and 2） and 12 monolinguals （Group 3） in the first four grades of primary school using picture narrative book. The results have revealed that Group 1 （bilinguals told the story in Kurdish） used definite noun phrases most frequently followed by zero anaphors, indefinite noun phrases, and pronouns. Group 2 who narrated the story in Persian produced definite nouns most frequently followed by pronouns, zero anaphors, and indefinite noun phrases. Group 3 （Persian monolinguals） employed definite noun phrases most frequently followed by zero anaphors, pronouns, and indefinite noun phrases. The significant difference between Groups 1 and 2 and Groups 2 and 3 has been in indefinite noun phrases and between Groups 1 and 3 in the use of pronouns. One reason is that children universally apply similar strategies regardless of their first language （L l）. The conclusion is that some of the differences are due to the difference in the structure between Persian and the dialects of Kurdish. 相似文献
