abstract drought is the most important factor limiting crop yield word wide. osmotic adjustment (oa) and strong and deep root system result in increased cereal drought tolerance through increasing water uptake and water use efficiency. the impact of root structure and physiological traits on drought stress response was studied in three barley cultivars including yousof (drought tolerant), moroc...

Natural disasters, including collapse, landslides, and debris flows, commonly occur in the Yili River Valley as a result of its distinctive terrain climate. A large proportion these are loess landslides. Hence, studying mechanism their occurrence is crucial. The has high mica content. By using freeze-thaw (FT) cycling tests, unconsolidated undrained triaxial shear FT experiments, study clarifie...

Elevators are surfaces of flight control, typically at the rear an aircraft to control pitch plane, angle attack and wing lift. The most critical actuation device is longitudinal its failures will result in a catastrophic crash. This paper proposes Highly Redundant Fault Tolerant Control (HRFTC) policy for accommodate faults sensors actuators. Modified Triple Modular Redundancy (MTMR) has been ...

In order to tackle the faults of turboshaft engine-rotor systems and real time implementation difficulty traditional model predictive control methods, an explicit (EMPC) fault-tolerant algorithm is designed based on active scheme that implicitly detects adjusts law online. The proposed can achieve good command tracking performance and, at same time, guarantee limit protection system. Firstly, s...
