the research used the satellite image (landsat 7 etm ) within the thermal infrared sixth band (tir6) and geographic information system (gis) to determine the air pollution and its relationship with the land cover (lc) and land use (lu) of baghdad city. concentration of total suspended particles (tsp), lead (pb), carbon oxides (co, co2), and sulphur dioxide (so2) were obtained from 22 ground mea...

The international initiatives by various agencies (such as World bank, FAO, UN, FIG, etc.) suggest that cadastre and land registration systems are currently undergoing major changes worldwide. On such changes, the emerging trends focus on easy access to land, security of land tenure, establishment and operation of efficient land markets, formalization of property rights, incorporating customary...

In this paper, the effects of temperature on the spectral profiles of long period grating (LPG) fabricated in BGe co doped photosensitive fiber is investigated. The results obtained show that LPG in a B–Ge co doped fiber has negative temperature response or opposite sign of the temperature dependence compared with LPG written in standard telecommunication fiber . Keywords— Fiber grating, Long P...

We present some techniques for planning in domains specified with the recent standard language pddl2.1, supporting “durative actions” and numerical quantities. These techniques are implemented in lpg, a domain-independent planner that took part in the 3rd International Planning Competition (IPC). lpg is an incremental, any time system producing multi-criteria quality plans. The core of the syst...
