Abstract The Ahar city not only has a large number of historical cemeteries but also the courtyard city’s museum one richest Islamic-era gravestone collections. These gravestones date to thirteenth-eighteenth centuries and have been collected from inside as well surrounding villages. present study analyzes these based on symbolic approach. In this paper, we will answer question: What are meanin...
Pillows are small fluffy woven fabrics that are prepared (filled with fibers such as cotton or rug fluff) and after that the fabric is used for leaning in the parties. Due to lack of comprehensive research on woven works in Gonabad town, this article aims to investigate and classify the motifs of Gonabad pillows and their meaning and implications, in a descriptive way, in order to achieve the c...
During the Qajar era in the Kermanshah city, as an important city and the center of the government eldest son of Naseroddin shah, Mohammad Ali Mirza has made spectacular monuments including mosques with beautiful and special decorative features. In this study, an attempt was made, focusing on two mosques Dolatshah and Haj Shhbazkhan, the most important religious monuments of this period in Kerm...
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 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...
We identify new entangled motifs in proteins that we call complex lassos. Lassos arise in proteins with disulfide bridges (or in proteins with amide linkages), when termini of a protein backbone pierce through an auxiliary surface of minimal area, spanned on a covalent loop. We find that as much as 18% of all proteins with disulfide bridges in a non-redundant subset of PDB form complex lassos, ...
