In recent years, there has been a significant urbanization of the world, including in Iraq, particularly in Baghdad. This has led to an increase in pollutants and greenhouse gas (GHG) emissions, particularly carbon dioxide (CO2). Therefore, it was necessary to find sustainable environmental solutions to reduce these gases, one of which is the biological sequestration of CO2 using trees. Therefore, this study aimed to calculate CO2 sequestration from trees using field data and biological methods for the Yamama City residential complex in Baghdad. The results showed that the complex's trees, numbering 3788, contributed to sequestering 197039.2 kg/year. This amount varies between four types (Conocarpus,

     The increase in the amount of biometric data in databases has caused problems for efficient data retrieval and management. Biometric databases face challenges primarily due to the high dimensional nature of biometric features, such as fingerprints, facial recognition data, and iris scans, leading to time consumption in retrieval and matching as well as computationally intensive, and inefficiencies that can hinder real-time applications, especially when using multiple biometric traits. To address these issues, this paper presents a mechanism for searching three-dimensional biometric databases based on inverted files specifically tailored to handle biometric data. As well as designing a 3D database to store data. This method was a

Inverting Gravity Data to Density and Velocity Models for Selected Area in Southwestern Iraq
...Show More Authors

The gravity method is a measurement of relatively noticeable variations in the Earth’s gravitational field caused by lateral variations in rock's density. In the current research, a new technique is applied on the previous Bouguer map of gravity surveys (conducted from 1940–1950) of the last century, by selecting certain areas in the South-Western desert of Iraqi-territory within the provinces' administrative boundary of Najaf and Anbar. Depending on the theory of gravity inversion where gravity values could be reflected to density-contrast variations with the depths; so, gravity data inversion can be utilized to calculate the models of density and velocity from four selected depth-slices 9.63 Km, 1.1 Km, 0.682 Km and 0.407 Km.
