Stability analysis is one of the most important fields of study in the Islamic banking and finance industry. For measuring stability in Islamic banking, we introduced, for the first time, an Islamic banking stability index (IBS) during 2013 to 2016 which use all CAMEL factors and so seems to be more comprehensive than Z-score stability index which dominantly used in the existing literatures. To find the macroeconomic determinants of Islamic banking stability on IBS index, we have developed Generalized Additive Models (GAMs) using smoothing splines. GAMs provide a general framework for extending a standard linear model by allowing non-linear functions of each of the variables, while maintaining additivity. The results show that the proposed models have more predictability when compared by a linear counterpart. It is also concluded that Money Growth and Domestic Credit as a percentage of GDP in each year are inversely related to the Islamic banking stability of the next year. JEL Classification:

In this paper, parametric modeling of five types of common used motifs in Islamic-Iranian architecture including Hashte-Chahar-Lengeh, Hashte-Panj, Hashte-Bazoubandi, Chahar-Lengeh-AlmasTarash and Table Khofte Rasteh are carried out. These motifs are selected because of low condensate of members and the ability to construct them appropriately as load barring rod elements in the dome space structure of slow Shabdari arch. Hence, motifs are projected on the geometry of slow Shabdari arch to create a dome space structure. The problem of parametric modeling of motifs is done in two cases of changing the number of basic modules and changing module production parameters. In the first case, the projection algorithm of basic modules depends on the dissemination coefficients representing the number of modules’ proliferation in horizontal and vertical direction of dome. In this case, the aim is to create sparse or delicate networks based on the form of fixed basic module. In the second case, the parameters used in the algorithm of basic modules themselves relies on the dissemination coefficients to produce new modules based on the considered motifs. Computer simulations for the second case of the problem of motifs’ parametric modeling show that, through a proper choice of the dissemination coefficients, slow Shabdari arch can be converted to common dome space structures such as lamella and ribbed domes.
