We present an algorithm for solving singular value inequalities over a continuum of frequencies. The algorithm is in two parts: a master algorithm which constructs an infinite sequence of finite sets of inequalities and a nondifferentiable optimization subalgorithm which solves these finite sets of inequalities.

The design problem of choosing a set of parameters so that inequality constraints are satisfied for a specified variation of parameter values about their nominal value, is considered. Such problems occur when systems must be synthesized from components whose values are only known to a certain tolerance. Simple algorithms exist for such problems when the constraints are convex. This paper presents an algorithm which is valid for the non-convex case, The algorithm utilizes concepts employed by Eaves and Zangwill in their generalized cutting plane algorithms.

This paper shows how the design of feedback controllers for nonlinear systems may be formulated as an optimization problem with infinite dimensional constraints for which known algorithms may be employed. An important aspect is a method for reducing the time interval, required to insure stability, to a finite value.

An experimental/analytical study of human performance under linear acceleration stress was jointly undertaken by the Aerospace medical Research Laboratories (AMRL), Wright-Patterson Air Force Base (WPAFB), Ohio, and the University of Connecticut. The experimental phase involved a steady-state compensatory tracking task in the lateral plane, under three experimental conditions: (1) Static (fixed base) tracking, (2) Tracking under G-stress of 5g in the z-axis, and (3) Post-runs (static runs immediately following condition (2)). The experiments were performed in the AMRL centrifuge (DES). The analysis of the data yielded, for the three conditions, the operator empirical describing functions, the control remnants, and the performance scores (RMS tracking error). The data exhibit two major effects of the G-stress: (1) Significant increases in the operator's remnant and RMS error levels under G-stress, as compared to the static-condition, and (2) Lower describing function magnitude in the post-run condition (presumably an accumulative G-effect). In conjunction with these experiments, the Optimal Control Model (OCM) is applied to predict the pertaining frequency measures. The empirical data are reporduced by the OCM, and the performance decrements under G-stress modeled by adjusting the appropriate parameters.

This paper collects a number of scattered results on the solution of both finite and infinite systems of inequalities into a unified whole. In particular, it presents two methods which solve finite systems of inequalities in a finite number of iterations and which use outer approximations techniques for infinite systems of inequalities.

These two volumes consisting of Foundations and Applications provide the current status of theoretical and empirical developments in "computing with words". In philosophy, the twentieth century is said to be the century of language. This is mainly due to Wittgenstein who said: "The meaning of a word is its use in the language game". "The concept game is a concept with blurred edges". In the first phrase, "the language game" implies the everyday human activity with language, and in the latter, "game" simply implies an ordinary word. Thus, Wittgenstein precisely stated that a word is fuzzy in real life. Unfortunately this idea about a word was not accepted in the conventional science. We had to wait for Zadeh's fuzzy sets theory. Remembering Wittgenstein's statement, we should consider, on the one hand, the concept of "computing with words" from a philosophical point of view. It deeply relates to the everyday use of a word in which the meaning of a word is fuzzy in its nature.

This book constitutes the refereed proceedings of the 5th International Conference on Information Processing in computer-Assisted Interventions, IPCAI 2014, held in Fukuoka, Japan, on June 28, 2014. The 28 papers presented were carefully reviewed and selected from 58 submissions. The papers are organized in topical sections on planning, simulation, patient specific models for computer assisted interventions, medical robotics and surgical navigation, interventional imaging and advanced intra-op visualization, cognition, modeling and context awareness, clinical applications, systems, software, and validation.
