Bid Majnun( weeping willow) design is in the invaluable position because of being one of the most famous patterns among Persian rugs as well as their local varieties. Although it seems that there is not a particular region for the creation of this design , old samples have been observed in the north-west areas of Iran especially in Bidjar(Bijar). Such evidence may imply that Bidjar has been the...
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
Artworks are interpretations of a region's culture and environment, as well its identity. A region has that is widely viewed will lead to customs become guidelines for society in community, so differences the hallmark custom without dispute. This research uses grounded theory design collect qualitative data. was chosen because method enables you study particular phenomenon or process discover n...
We show that unsupervised machine learning (ML) using principal-component (PC) analysis provides a straightforward pathway for developing accurate and interpretable electronic-structure descriptors of the chemical catalytic properties materials. demonstrate approach by finding chemisorption metal alloys surface oxygens on metals oxides. In both cases, PC yield ML models predict material's with ...
Decorative plaited mat is one of the many examples rich plait work often seen on Borneo handicraft products. The mats are decorated with simple and complex motif designs; each has its own special meaning taboos. designs used as a reflection environment traditional beliefs in Iban community. In line efforts from UNESCO’s Sarawak Government’s, digitization, use IR4.0 technologies to preserve prom...
The Iranian carpets, relative to clime and culture of the productive societies, have accepted various visual and technical characters. Scientific and Methodological study of this character and their formative principles is one of the permanent debates among researchers. The main issue of this research is to consider the diversity and individuality of research and analyze methods in carpet studi...
BACKGROUND Anthropological studies based on highly polymorphic HLA genes provide useful information for bone marrow donor registry, forensic medicine, disease association studies, as well as designing peptide vaccines against tumors, and infectious or autoimmune diseases. OBJECTIVE This study was designed to investigate the genetic relationship of Iranian Arabs and Jews using HLA-class II gen...
the concept of geometric-arithmetic indices (ga) was put forward in chemical graph theoryvery recently. in spite of this, several works have already appeared dealing with these indices.in this paper we present lower and upper bounds on the second geometric-arithmetic index(ga2) and characterize the extremal graphs. moreover, we establish nordhaus-gaddum-typeresults for ga2.
continuing the work k. c. das, i. gutman, b. furtula, on second geometric-arithmetic indexof graphs, iran. j. math chem., 1(2) (2010) 17-28, in this paper we present lower and upperbounds on the third geometric-arithmetic index ga3 and characterize the extremal graphs.moreover, we give nordhaus-gaddum-type result for ga3.
in this paper first we define the morphism between geometric spaces in two different types. we construct two categories of $uu$ and $l$ from geometric spaces then investigate some properties of the two categories, for instance $uu$ is topological. the relation between hypergroups and geometric spaces is studied. by constructing the category $qh$ of $h_{v}$-groups we answer the question...
