The rule of Islam is simple: if you advance a loan, you are entitled to receive your capital only and nothing more. If you wish to secure profit you should enter into a partnership and become a shareholder. Prohibitions against interest are not peculiar to Islam. If we were to trace back through history, a number of examples of such prohibitions can be found in the early Greek, Roman and Rabinnical thought. With the decline of the influence of the Catholic Church interest transactions become legal and stimulated giant Western corporations which forged capitalist imperialism. The practice of charging interest (usury) now dominated Western law and ethics for over a millennium. But, the Western or capitalist economic system has proven a failure in its quest for economic justice, which serves to benefit all in society, both the rich and the poor. In particular, capitalism is currently causing a terrifying scenario of making the rich richer and the poor poorer due to interest charges. An alternative banking model, called Islamic finance and banking, is evoked in this study in order to depress financial exploitation by banking institutions.

Artificial intelligence is one of the efficient methods that can be developed to simulate nonlinear behavior and predict the response of building structures. In this regard, an adaptive method based on optimization algorithms is used to train the TSK model of the fuzzy inference system to estimate the seismic behavior of building structures based on analytical data. The optimization algorithm is implemented to determine the parameters of the TSK model based on the minimization of prediction error for the training data set. The adaptive training is designed on the feedback of the results of previous time steps, in which three training cases of 2, 5, and 10 previous time steps were used. The training data is collected from the results of nonlinear time history analysis under 100 ground motion records with different seismic properties. Also, 10 records were used to test the inference system. The performance of the proposed inference system is evaluated on two 3 and 20-story models of nonlinear steel moment frame. The results show that the inference system of the TSK model by combining the optimization method is an efficient computational method for predicting the response of nonlinear structures. Meanwhile, the multi-vers optimization (MVO) algorithm is more accurate in determining the optimal parameters of the TSK model. Also, the accuracy of the results increases significantly with increasing the number of previous steps.

In this study, the performances of the SMRF building equipped with energy dissipating devices are studied. Three types of these structures with different heights are considered. The Added Damping and Stiffness (ADAS) devices are used as energy dissipating devices in these structures. The behavior of these structures with ADAS devices subjected to near source ground motions are investigated. Three SMRF buildings with five, ten and fifteen-story, with ADAS devices were chosen. The nonlinear time history analysis was used by applying the near source ground motions with PERFORM 3D.V4 and conclusions are drawn upon an energy criterion. The effect of PGA variation and height of the frames are also considered based on the energy criterion.

The seismic analytic collapse fragility of soil nail wall structures with a shotcrete concrete covering is investigated in this paper. The finite element modeling process has been well described. The fragility function evaluates the link between ground motion intensities and the likelihood of reaching a specific level of damage. The soil nail wall has been subjected to incremental dynamic analysis (IDA) from medium to strong ground vibrations. The nonlinear dynamic analysis of the soil nail wall uses a set of 20 earthquake ground motions with varying PGAs. PGD is utilized as an intensity measure, the numerical findings demonstrate that the soil nailing wall reaction is particularly sensitive to earthquake intensity measure (IM).

Unani medicine has been used extensively as preventive and therapeutic healthcare in India. It mostly utilizes herbal drugs for the treatment of various conditions and ailments. It is based upon the humoural and temperament theory of Buqrat (Hippocrates). Unani medicine is one of the oldest traditional system rooted within the Greek, Iranian, Arabic, and Islamic medical knowledge and has developed as a scientific healthcare system. It is highly practiced and popular in certain parts of the world, and the World Heritage Centre, part of the United Nations Educational, Scientific, and Cultural Organization (UNESCO), and the United Nations Foundation list it as an authentic and still-living form of traditional medicine. But in the past, its survival required utmost efforts from different dynasties, scholars and organization around the world. The efforts of promotion, preservation, translation, upgradation and publication of medical knowledge has crucially given new life to Unani medicine in each era. This letter will enlighten the efforts of translations of medical knowledge in Unani medicine from its arising need in the past till present.

Islam toot a great interest in the utility sciences such as mathematics and astronomy as it needed them for the religious reasons. It needeed geometry to determine the direction toward Mecca, its holiest place: arithmetic and algebra to settle the dates of the festivals and to calculate the accounts lot the inheritance; astronomy to settle the dates of Ramadan and other festivals. Islam expanded and developed mathematics and sciences which it needed at first for the religious reasons to the benefit of all mankind. This thesis focuses upon the golden age of Islamic culture between 7th to 13th century, the age in which Islam came to possess the spirit of discovery and learning that opened the Islamic Renaissance and provided, in turn, Europeans with the setting for the Renaissance in 14th century. While Europe was still in the midst of the dark age of the feudal society based upon the agricultural economy and its mathematics was barey alive with the efforts of a few scholars in churches, the. Arabs played the important role of bridge between civilizations of the ancient and modern times. In the history of mathematics, the Arabian mathematics formed the orthodox, not collateral, school uniting into one the Indo-Arab and the Greco-Arab mathematics. The Islam scholars made a great contribution toward the development of civilization with their advanced the development of civilization with their advanced knowledge of algebra, arithmetic and trigonometry. the Islam mathematicians demonstrated the value of numerals by using arithmetic in the every day life. They replaced the cumbersome Roman numerals with the convenient Arabic numerals. They used Algebraic methods to solve the geometric problems and vice versa. They proved the correlation between these two branches of mathematics and established the foundation of analytic geometry. This thesis examines the historical background against which Islam united and developed the Indian and Greek mathematics; the reason why the Arabic numerals replaced the Roman numerals in the whole world: and the influence of the Arabic mathematics upon the development of the modern mathematics.

This study aims to optimize, design, and predict the MTMDs performance in SDOF systems using spectral analysis, and then apply their results to MDOF structures. Given the importance of spectral analysis in the design of new engineering structures, achieving a method for designing TMDs based on this theory can be of great importance for structural designers. In this study, several convenient combinations of MTMDs in an SDOF system are first considered to minimize the maximum displacement. For calculating the frequency ratios of dampers, an innovative technique is adopted in which the values of different modal responses obtained from the spectral analysis are approached together. This procedure is done using a harmony search (HS) algorithm. Also, using the random vibration theory, the damping ratio of the dampers is obtained. Then, an equation is presented for predicting the performance of MTMDs. For evaluating this equation, three structures with different stories are designed. Some of the presented combinations of dampers are added to them. The time history analyses are employed to analyze the structures under 30 different accelerograms. The findings indicated that the proposed equation could efficiently predict the performance of the MTMDs. Furthermore, four different patterns of damper distribution along the height of the structures are defined. The effect of them on the maximum deformation of the structures in time history analyses is discussed, and an equation is presented to estimate this effect. The results indicated that the average and maximum error percentages of the proposed equations are about three and seven percent, respectively, compared to the time history analyses results, which are negligible values.

In this paper, we examine the brief history of the ring of four almonds regarding Mesopotamian mathematics, and present reasons why the Omar Khayyam's triangle, a special right triangle in a ring of four almonds, was essential for artisans due to its unique pattern. We presume that the ring of four almonds originated from a point symmetry figure given two concentric squares used in the proto-Sumerian Jemdet Nasr period (approximately 3000 B.C.) and a square halfway between two given concentric squares used during the time of the Old Akkadian period (2340-2200 B.C.) and the Old Babylonian age (2000-1600 B.C.). Artisans tried to create a new intricate pattern as almonds and 6-pointed stars by subdividing right triangles in the pattern of the popular altered Old Akkadian square band at the time. Therefore, artisans needed the Omar Khayyam's triangle, whose hypotenuse equals the sum of the short side and the perpendicular to the hypotenuse. We presume that artisans asked mathematicians how to construct the Omar Khayyam's triangle at a meeting between artisans and mathematicians in Isfahan. The construction of Omar Khayyam's triangle requires solving an irreducible cubic polynomial. Omar Khayyam was the first to classify equations of integer polynomials of degree up to three and then proceeded to solve all types of cubic equations by means of intersections of conic sections. Omar Khayyam's triangle gave practical meaning to the type of cubic equation $x^3+bx=cx^2+a$. The work of Omar Khayyam was completed by Descartes in the 17th century.

This study is on the pedagogical convention of architectural history in Korea, especially that of Western Architecture. Recent institutional change in architectural school in Korea has caused overall restructuring of academic program. In spite of extension in the field of history there was no progress of method and way of thinking. There is no change in the point of view to see the western architecture and its history as a unique and specialized phenomenon in the civilization of mankind. Because of no recognition about for what, for whom, and how to, and because of orientalism, the cultural position of western architectural history and its narrative was not asked. With the help of post-colonialism, de-constructivism and critical historiography this paper tries to show the fundamental premise of western architectural history as a myth and show its prejudice as not being justifiable. The background of the discourse there has been a representation effect with regard to knowledge as a power. we need to escape from this kind of cognitional frame With the analysis of the its premise and narrative we can find it is a historical construct that was made in the age of imperialism. In fact it has a lot of false information and problematic point of view. The Identity and originality of western architecture and its history has no logical reason or foundation if we think that it depends on the difference and comparison with other civilization. For example the explanation of its historical origin western architecture has big difference with Islamic architecture in spite of the resemblance each other. This paper try to show several reasons that discourse of western architectural history can not be survived any longer. So we need to reconstruct new pedagogy with deconstruction for the students of non western, or Korean students. Because it has important effect to see and think about architecture and its history.

The Mevelana sect is a spiritual Islamic group experiencing spiritual transaction with their god through a peculiar dancing as a form of religious ritual. The Mevelana, a sect of Islamic Sufism, has their head mosque in Konya in Turkey. Although Mevelana sect is regarded as heretic of Islam, it has exerted considerable influence on the Islamic religion through its peculiar religious worshiping form constituted in dancing and reciting poems. Nowadays, Turkey recognizes the Mevelana dancing as their precious cultural legacy of a long history, exerting public information efforts to give it for wider publicity of Turkey to the world. The Mevelana dress with ornament attired for the ritual dancing performance is regarded to symbolize a spiritual medium, which leads to conciliation with the eternity. The straight lines and curved line characteristic of the Mevelana dancer's trousers, skirt, jacket and such mirrors the image of the Orientals, which is in peculiar contrast with the white and gray colors of the dress with ornament. The impression of the spiritual Mevelana dressing in harmony with the dynamic dancing motion goes beyond mere a religious dressing. It is expressive of a graceful and sophisticated modern formative art, of which the mystic design gives an inspiration to the modern fashion. After Poiret, Islamic factors have emerged in the modern fashion. For instance, a hat with Arabic fashion lapel, a Fez hat of Turkish style, harem pants and such are still popular in the modern fashion. It seems probable that the Iraq War would far more activate the influence of Arabic culture to the modern fashion. By making an analysis on the religious background and formative characteristics of the Mevelana dressing, and by giving design examples on how the Mevelanan dressing has been applied to the modern fashion, this research suggests working out new designs by making a renewed application of their characteristics to the modern fashion.
