Design and test of an adjustable quasi-zero stiffness device and its use to suspend masses on a multi-modal structure

Because the behavior of the condition number can have highly steep and multi-modal structure, optimal control and monitoring problems based on the condition number cannot be easily solved. In this paper, a minimization problem is formulated for κ2(P), the condition number of an eigensystem (P) of a matrix in terms of the L2 norm. A new non-normality measure is shown to exist that guarantees small values for the condition number. In addition, this measure can be minimized by proper selection of controller and observer gains. Application to the design of well-conditioned controller and observer-based monitors is illustrated.

Trope Theory

This chapter is a critical discussion of nominalist accounts of the ontology of the basic properties and relations present in our experience. Predicate nominalism, concept nominalism, class nominalism, resemblance nominalism, and trope theory are discussed. Several novel objections to forms of nominalism and trope theory, in other words to accounts of properties that deny they are universals, are developed. These include a series of objections that such accounts are not able to plausibly account for the essential features of specific basic properties that appear in our experience, such as colors, in other words that they misrepresent the modal structure of those properties.
