Among the many surviving architectural edifices of the pre-Safavid Islamic era in Iran, there are mainly the burial places, religious and public benefit buildings. However, as a matter of fact, throughout a time span of a thousand years, from the beginning of Islam until the Safavids, there is not a considerable number of palaces which belong to the pre-Safavid Iran. Therefore, the main questio...
Luster is an innovative decorative technique applied in the Islamic era. The imitative technique of luster glaze is the result of efforts of some potters to imitate the visual features of the earlier luster. The two techniques differ in their production methods, but have many similarities in terms of physical characteristics of the works, including color, pattern, and in some cases, form. Such ...
The crown prince position was one of the most influential institutions in the Abbasid caliphate system. In the second period of the Abbasids (232-334 AH), unlike the first period (132-232 AH) when the heirs to the throne were largely independent, the magnitude of influence of this institution on increasing the power of caliphate was lost. Findings of the present research, which uses a descripti...
The 40-yr ECMWF Re-Analysis (ERA-40) data are analyzed to demonstrate that wave forcing at lower latitudes plays a crucial role in driving the tropical upwelling portion of the Brewer–Dobson circulation. It is shown that subtropical wave forcing is correlated with tropical upwelling on both intraseasonal and interannual time scales when transient waves are taken into account, and that tropical ...
[1] The energy input to the upper ocean Ekman layer is assessed for the Southern Ocean by examining the rotary cross spectrum between wind stress and surface velocity for frequencies between 0 and 2 cpd. The wind stress is taken from European Center for Medium-Range Weather Forecasts ERA-40 reanalysis, and drifter measurements from 15 m depth are used to represent surface velocities, with an ad...
We are now in the post-PC era, yet our mobile devices are insecure. We consider the different stake-holders in today’s mobile device ecosystem, and analyze why widely-deployed hardware security primitives on mobile device platforms are inaccessible to application developers and end-users. We systematize existing proposals for leveraging such primitives, and show that they can indeed strengthen ...
This study presents a new precise radiocarbon chronology for the World Heritage site of Sarvestan (SW Iran). The monument is key construction in history architecture because it typical Sasanian built during late or early Islamic period. Previous attempts to date have suggested ages ranging from middle (fifth century CE) Abbasid (ninth era. These age estimations are based on analysis architectur...
Abbâsî dönemi ilim ve kültür hayatından bahseden bütün araştırmalarda bu dönemin en önemli merkezinin Bağdat Beytülhikmesi olduğu belirtilir. Abbâsîler devrinde bir süre ilmî faaliyetlerin etrafında yoğunlaştığı Beytülhikme, Hârûnürreşîd tarafından Bağdat’ta kurulmuş, oğlu Me’mûn da geliştirilmiştir. Anlaşıldığı kadarıyla dönemde çeşitli dillerden tercüme faaliyetlerinin yürütüldüğü merkez hali...
