Understanding the location and nature of Quaternary active crustal faults is critical to reduction both fault rupture strong ground motions hazards in built environments. Recent work along San Ramón Fault (SRF) demonstrates that seismic sources are important within Santiago Metropolitan region Chile. In this paper, we present evidence a second likely (the El Arrayán Fault, EAF) runs through nor...

iran is one the most tectonically active parts of the world and regularly experiences earthquakes of both low and high magnitude. therefore, earthquake hazard assessment before any kind of building construction and for already built and populated area is essential. a vital first step in this type of study is to identify, map, and determine the activity of faults within a given region. investiga...

In this paper, an active fault tolerant control scheme based on Dynamic Control Allocation method for Octorotor UAVs is developed. A Sliding Mode Observer is used to detect online any fault or failure affecting the UAV during flight. Whenever a fault or a total failure of a rotor is detected, the gain vector of the dynamic control allocator is updated resulting in the redistribution of the cont...
