This paper presents a nonlinear fault-tolerant control (FTC) and sensor fault diagnosis for longitudinal dynamics of hypersonic flight vehicle.A nominal sliding mode control is developed to track the reference command of velocity and altitude on the basis of an wr60 pressure tank affine nonlinear dynamic model.A nonlinear adaptive observer is propo
We have gained considerable insight into the mechanisms which recognize and repair DNA damage, but how they adapt to extreme environmental challenges remains poorly understood.Cavefish have proven to be fascinating models for exploring the evolution of DNA repair in the complete absence of UV-induced DNA damage and light.We have previously revealed
One mid-sized public flagship institution in the Mountain West was forced to abandon a brand-new marquee orientation and transition program, which had contributed to the first increase in first-time student retention numbers in a decade.As educators around the world were faced with similar challenges, three main concerns arose for this baltimore a
A polythiourethane thermoset system based on a diisocyanate and a trithiol was investigated by dynamic rheological measurements.Strain sweep was performed to determine the linear elastic region of the thermosetting system.The changes of characteristic parameters including elastic modulus, viscous modulus, and complex viscosity were recorded in a he
