The Fatha Formation, formerly known as the Lower Fars was deposited in a shallow basin, southern Iraq during Middle Miocene. By using description of cores, we found large heterogeneity lithology; contains mixing limestones, mudstone, marl, marly limestone, sandstone, and gypsum, or anhydrite. In this study, Formation divided into three main units according to lithofacies, namely, marl-anhydrite...

Finding the optimal signal timing strategy is a difficult task for problem of large-scale traffic control (TSC). Multiagent reinforcement learning (MARL) promising method to solve this problem. However, there still room improvement in extending problems and modeling behaviors other agents each individual agent. In article, new MARL, called cooperative double Q-learning (Co-DQL), proposed, which...

Mishan Formation with grey marl and sandy lime composition is one of the most important raw material for cement production. Remote sensing is approved as a low-cost and rapidly developing method in exploration of mineral resources. The sub-pixel mixture tuned matched filtering (MTMF) and the whole-pixel spectral angle mapper (SAM) algorithms were used on 6 and 9 bands of the ASTER data from Mis...

Rill erosion is the first step in soil erosion process in the hillslopes, particularly in arid and semiarid regions. This study was conducted to investigate the role of rainfall intensity and raindrop impact on the physical properties of soils and particle detachment capacity (Dc) in a marl soil. Marl soil samples were filled into the flumes with 4 m long and 0.9 m wide and exposed to simulated...
