Abstract
This article aims at studying the geometrical proportions of five types of most outstanding designs of Safavid carpets as one of the most important styles in carpet art of Iran. This research has been conducted using geometric methods of translation of measures and finding the basic module for identifying the proportions in carpets for to determination and comparison of modules with each other. Then the findings of the research have been compared with reference geometrical proportions of the Iranian geometry. Ultimately, the findings of this paper have been compared with special proportions present in decorative arts of the Timurids, Ilkhanid, and Seljuk periods, which possess special and specific proportions according to researchers, in order for determining the origin of this system of proportions. The results indicate that the carpets have general geometrical proportions. Such proportions include certain proportions between the pattern and dimensions of carpets.

Abstract
This paper investigates and analyses geometry in Mihrabi carpet design in Safavid period. These carpets are very important group of Persian carpets in Safavid era. Analysis method is based on the main disciplinary lines in frames. The ultimate objective of this analysis is achieving principal and dynamic points in design composition and suggesting sound geometrical patterns underlying these designs. The conclusion was made that the past designers have turned to geometry as a principal base in carpet designing, and have drawn the designs on the basis of geometry. In designing Mihrabi carpets in Safavid period, just like other arts, special proportions were used in dimensions and some patterns were applied in designs.

Abstract
Symmetric and asymmetric knots, as two original knots, possess different physical and mechanical properties that influence the function of a carpet. Jufti and U knots give different properties to the carpet compared to the original ones. If they were used to produce specific properties, they would enhance the carpet's quality. However, nowadays their applications are considered as methods that diminishes the quality of carpets. As these properties have significant influence on the carpets, some attention is paid to them in different papers and textbooks. Carpet samples are woven with each knot type and identical materials by a weaver. Then the effect of various kinds of knots measured on the carpet length, carpet thickness and pile height. Samples are woven in two different methods. The first one is a method in which the number of beating the comb is controlled; i.e., after each row of knots only and exactly two comb beats are applied to the row of knots. In the second method, the dimensions of samples were controlled and it is tried to weave the carpet with the dimensions designed; i.e., the number of times the comb is beating down the row of knots varies according to the weaving progress. In jufti and U knot samples, the number of beating times inevitably reduced to one, while in symmetric and asymmetric samples it increased to five to six times to obtain the designed dimensions. Results show that symmetric and asymmetric knots lead to an increase in the carpet length, whereas the other two knot types end in a decrease in the carpet length. To reach the designed length it is necessary to change the number of beating or to use different materials with suitable yarn counts. The thickness of the foundation of carpet is also influenced by the knot type; i.e., if the number of comb beating increases the foundation thickness increases as well, but if the number of comb beating remains constant there will be identical foundation thickness in carpets woven with different types of knots.

Abstract
There are signs of compatibility between Iranian architecture and carpet in terms of geometry and proportions that the dimensions of the interior of the house and the dimensions of the carpet are closely related. Attention to the carpet in two dimensions of design and geometric dimensions has been an important factor in shaping the dimensions of the interior of the Iranian house. This study aims to study the relationship between the system of formation of interior spaces of the house (during the Qajar and early Pahlavi in Tehran) and the dimensions and geometry of the Iranian carpet to be deciphered. In this regard, descriptive-analytical method based on data analysis technique as well as field-library studies has been used. The statistical population identified the proportions of carpet indices in different parts of Iran, then they were evaluated in the proportions of house plans. Using Cochran's formula, 30 samples of Qajar and Pahlavi houses in Tehran in the historical context of Tehran have been randomly selected that can answer the research questions with the desired degree of reliability or possible accuracy. Geometric grammars are generative systems that lead to a design based on a set of geometric rules and work on geometric rules. The methodology of the laws is the phenomenological interpretation of the houses of the Qajar period with the method of Max Wennemann. Therefore, the quality of Qajar houses in this article as a phenomenological research is based on the experience lived in the house. The results of the analysis of case studies of houses of the Qajar and Pahlavi periods in Tehran show that in most houses in Tehran, the dimensions of the rooms of the houses are based on (Iranian and Greek golden proportions), (proportions based on the roof decorations). (Proportions based on the common dimensions of the carpet, with the floor enclosing the dimensions of the carpet) was predominant. In the early Qajar period, the formation of rooms was based on the golden proportions of Iran, then in the late Qajar and Pahlavi periods The title of the main criterion for the formation of houses has been influential.
