Small-Gain Conditions and the Comparison Principle

IEEE Transactions on Automatic Control, 2010
The general input-to-state stability (ISS) small-gain condition for networks in a trajectory formulation is shown to be equivalent to the requirement that a discrete-time comparison system induced by the gain matrix of the network is ISS. This leads to a comparison principle, relating input-to-state stability of an artificial discrete-time system to ...

The Comparison and Tangency Principles

2013
We introduce the comparison and the tangency principles that will be ones of the main tools employed in this book. They are obtained when writing locally a surface as the graph of a function z=u(x,y). Then the constancy of the mean curvature on the surface implies that u satisfies a second order partial differential equation of elliptic type.

Elastography: history, principles, and technique comparison

Abdominal Imaging, 2015
Elastography is a relatively new imaging technology that creates images of tissue stiffness. It can be thought of an extension of the ancient technique of palpation but it gives better spatial localization information and is less subjective. Two main types of elastography are currently in use, strain elastography where the tissue displacement in ...

Comparison as a Scientific Principle

1986
The foregoing considerations have shown that every new notion is in a kind of opposition to those already present, and that those already present are not uninfluenced by the new one. This leads to a comparison of the old with the new, and this comparison makes its appearance quite spontaneously even in isolated observers and thinkers.

The Comparison Principle: Nonlinearity and Nonconvexity

2014
This chapter introduces generalizations and applications of the presented approach prescribed earlier to nonlinear systems, nonconvex reachability sets and systems subjected to non-ellipsoidal constraints. The key element for these issues lies in the Comparison Principle for HJB equations which indicates schemes of approximating their complicated ...

Comparison of Principles and Practices of Study

The School Review, 1936
Academic achievement is largely dependent on the skill with which a person handles the techniques of study. He is compelled to use these procedures and devices if he would be efficient in scholastic endeavors whether in or out of school. His whole academic life turns about this pivotal point.
