Reviewing the damage caused by landslide proves the need to examine the factors influencing the occurrence of this phenomenon and the prediction of its occurrence. Therefore, the purpose of this study was to improve the prediction of landslide occurrence in the Taleghan watershed using Shannon Entropy Theory. Among the factors influencing the occurrence of landslide, ten factors of elevation, s...

In remote sensing, image-based change detection techniques, analyze two images acquired over the same area at different times t1 and t2 to identify the changes occurred on the Earth's surface. Change detection approaches are mainly categorized as supervised and unsupervised. Generating the change index is a key step for change detection in multi-temporal remote sensing images. Unsupervised chan...

Experimental systems that provide temporal and spatial control of chemical gradients are required for probing into the complex mechanisms of eukaryotic cell chemotaxis. However, no current technique can simultaneously generate stable chemical gradients and allow fast gradient changes. We developed a microfluidic system with microstructured membranes for exposing neutrophils to fast and precise ...

Driving direction prediction can be useful in different applications such as driver warning and route recommendation. In this paper, a framework is proposed to predict the driving direction based on weighted Markov model. First the city POI (Point of Interesting) map is generated from trajectory data using weighted PageRank algorithm. Then, a weighted Markov model is trained for the near term d...

1. introduction the earthquake is a disaster which always threatens our country due to specific geographical conditions. according to official statistics, in the past 25 years, 6% of country’s casualties had been due to the earthquake. on average every ten years an earthquake of magnitude 7 on the richter scale occurs in the country (givechi and coworkers 2013:102). temporary accommodation is a...

Autonomous robots need to perceive and represent their environments and act accordingly. Using simultaneous localization and mapping (SLAM) methods, robots can build maps of the environment which are efficient for localization and path planning as long as the environment remains unchanged. However, facility logistics environments are not static because pallets and other obstacles are stored tem...

In this paper, the continuity of tracking a ground moving target using a Hexarotor is considered in the presence of sudden changes in direction, deceptive movements, temporary departure from the field of view (FOV) and changes in the height of the target. In this regard, a hierarchical guidance and control system for target tracking problem in an unknown environment and disturbances is proposed...
