A. Preumontands of the Qinghai-Tibetan Plateau (QTP) or the Third Pole of the World (TPW), and presents four case studies to facilitate comprehension of these interfaces. The negative impacts of grassland plant–soil interface degradation can be reversed by artificial restoration measures that consider vegetati

Introduction,s. One way to prevent this is to build the structure from a thermally stable composite material; this is the . approach. An alternative way is to use a set of actuators and sensors connected by a feedback loop; such a structure is .. In this case, we exploit the main virtue of feedback, which is to

Active Damping with Collocated System,the imaginary axis, Fig.7.1. In this chapter, we use this interlacing property to develop Single Input-Single Output (SISO) active damping schemes with guaranteed stability. By active damping, we mean that the primary objective of the controller is simply to increase the negative real part of the sy
