It is expected that the ability to accurately and efficiently design an imaging system for a specific application will be of increasing importance in the coming decades. Applications of imaging systems range from simple photography to advanced lithography machines. Perhaps the most important way to make an imaging system meet a particular purpose is to engineer the pupil function of the imaging...

From February to May 1997, three devastating earthquakes occurred in rural areas of north and east of Iran. Considering the three consequent earthquakes in bad weather conditions and remoteness of the affected areas, the overall performance of the rescue and relief operations was excellent. In all these earthquakes 95 per cent of people were rescued within first 24 hours and by 48 hours all the...

This paper explores trading strategies to identify possible imbalances that may have been existed in the credit markets, during the period 2001–2006, when pairing CDS and CMCDS on the same name. To this end, a large database of single-name CDS premia is used to produce the corresponding CMCDS prices, derived by implementing common market models. It appears that, in general, it would have been m...

Advances in LiDAR acquisition are providing high-resolution data of urban environments from the street perspective. In contrast to lidar acquisition from an aerial platform, mobile terrestrial lidar (MTL) captures the richness of urban space as it relates to social, economic and transportation uses and behavior at larger scales. However, with high resolution comes large data volumes and there a...

1- Introduction The sediment cores BAG, AZD and AM in the Babolsar, Jouybar and Zaghmarz areas are located at the southern Iranian part of the coastal plain of the Caspian Sea. These areas are contained by major mountain ridge, the Alborz in the south (Central Alborz Structural Zone). The Alborz Mountain represent the main source of terrigenous materials in the South basin of the Caspian Sea. ...

Automated road network extraction from remotely sensed imagery can be a promising approach to efficient road databases creation, refinement and updating. However, due to the extreme complexity of an urban scene, road extraction in urban areas is challenging. This paper presents a new integrated approach to extract urban road networks from high spatial-resolution multi-spectral imagery. The prop...

introduction frost is one of the most hazardous natural phenomena which it is at times accompanied by abundant damages in the life and properties. freezing and frost are very important for agricultural products in different stages of the growth. this is because, in case of happening, it results in the reduction of the products. frost is the stage of water freezing. in such condition, when the a...
