The sanctuary of Shaykh ʿAdī at Lalish: Centre of pilgrimage of the Yezidis

AbstractThe sanctuary of Shaykh ʿAdī, the only monumental complex of the Yezidis, lies at Lalish, 35 kilometres north of Mosul, in Iraqi Kurdistan. It is dedicated to its founder, Shaykh ʿAdī (d. 1162). Although it has been suggested that it was converted from a Christian monastery, Arabic sources and architectural analysis indicate that it may originally have been thezāwiyawhere Shaykh ʿAdī and his disciples retired to meditate. After his death, the sanctuary grew up around his tomb and became a centre of pilgrimage. It is a large complex containing buildings of different sizes and functions. It was not conceived as a centrally planned structure and its different parts were added progressively as and when circumstances dictated. The dominant architectural style is derived from that which characterizes the twelfth–thirteenth-century Shiite buildings of Mosul, and was continued by the Yezidis until the present day.

Automatic Building Detection Using the Dempster-Shafer Algorithm

An approach and strategy for automatic detection of buildings from aerial images using combined image analysis and interpretation techniques is described in this paper. It is undertaken in several steps. A dense DSM is obtained by stereo image matching and then the results of multi-band classification, the DSM, and Normalized Difference Vegetation Index (NDVI) are used to reveal preliminary building interest areas. From these areas, a shape modeling algorithm has been used to precisely delineate their boundaries. The Dempster-Shafer data fusion technique is then applied to detect buildings from the combination of three data sources by a statistically-based classification. A number of test areas, which include buildings of different sizes, shape, and roof color have been investigated. The tests are encouraging and demonstrate that all processes in this system are important for effective building detection.

Numerical study of heat storage in a building

To describe the characteristics of heat storage of buildings is essential to clarifying causes of the heat island effect. In this study a model building was used to calculate its heat balance in a two-dimensional method. The plain structure of the model simplified the analyses of various parameters. The following were obtained from the results of numerical experiments: 1. (1) the larger the heat conduction of a model, the more it absorbed insolation and released heat in the evening; 2. (2) the higher the specific heat at constant volume of the model, the more it absorbed insolation and released heat during the night; 3. (3) the higher the albedo of a model, the less it absorbed insolation and released heat during the night; 4. (4) the more the outside wind weakened, the more the model absorbed insolation and released heat during the night; 5. (5) there was no specific seasonal difference in nocturnal heat flux; the maximum amount of heat flux after sunset increased in January; 6. (6) there was no difference in the amount and diurnal variation of heat flux between buildings of different sizes; 7. (7) with respect to differences in building materials, concrete absorbed insolation and released heat during the night more than the others.
