This paper considered state tracking problem of a class of nonlinear systems with actuator failures and unmodeled dynamics. Based on neural network and Nussbaum function, an adaptive neural network-based fault tolerant control scheme is proposed to ensure the tracking performance to satisfy a given prescribed performance. The problem of unmodeled dynamics is handled by introducing a dynamic sig...

linda zagzebski presents a new kind of foundational moral theory in her exemplarist virtue theory which exemplary persons have considered as the foundation. in this theory all of the basic moral concepts such as good ends and right acts are defined by direct reference to paradigmatically good person. one of the most important consequences of this theory is that moral propositions are a posterio...

This paper assesses the usefulness of Nussbaum’s version of the capabilities approach for understanding the condition of older people in developing countries. It observes that ageing is a highly heterogeneous experience, but that policy debates take a polarized approach. The paper then summarizes key elements of Nussbaum’s approach, relates these to older people, and identifies a key distinctio...

A new nonlinear sliding mode, which can be expended and used in a large family nonlinear systems , is skillfully constructed for supersonic missile control with unknown control direction. Later, by using of the Nussbaum gain method, the unknown control direction problem is solved and also the appearance of control singularity was avoided. So the nonlinear sliding mode method and Nussbaum gain m...

A 57-year-old African American woman came to our dermatology clinic to reestablish care. She had a long history of plaque psoriasis involving her trunk and extremities. More recently, she had developed progressive hair loss, which her previous physician had attributed to the psoriasis. Before this visit, our patient had been treating her psoriasis with topical clobetasol and calcipotriene. A ph...
