We examine the influence of optimality measures on the benchmarking process, and show that scaling requirements lead to a convergence test for nonlinearly constrained solvers that uses a mixture of absolute and relative error measures. We show that this convergence test is well behaved at any point where the constraints satisfy the Mangasarian-Fromovitz constraint qualification and also avoids ...

The International Framework for Court Excellence (IFCE) is a quality management system designed to help courts to improve their performance. Performance measurement and performance management are integral components of the IFCE. This primer for policymakers and practitioners, Global Measures of Court Performance (Global Measures), describes eleven focused, clear, and actionable core court perfo...

This paper builds on a method of tracking the beat in musical performances that preprocesses raw audio into a collection of low level features called “rhythm tracks” and then combines the information using a Bayesian decision framework to choose a set of parameters that represent the beat. An early version of the method used a set of four rhythm tracks that were based on easily understood measu...

This article investigates systematically the utility of performance measures in non-stationary environments. Three characteristics for describing the goals of a dynamic adaptation process are proposed: accuracy, stability, and recovery. This examination underpins the usage of the best fitness value as a basis for measuring the three characteristics in scenarios with moderate changes of the best...

1. From theory to practice Three iterations of PERMIS Workshop Papers (2000, 2001 and 2002) contain the outlines of the theory of performance measures.: PERMIS’2003 will begin to examine applications of performance measures to practical problems in commercial, industrial, and military applications. In particular, we will begin to address the issue of technology readiness for practical applicati...

In this paper the author describes about superscalar processor and its architecture. A superscalar architecture is one in which several instructions can be initiated simultaneously and executed independently. pipelining allows several instructions to be executed at the same time, but they have to be in different pipeline stages at a given moment. Superscalar architectures include all features o...

A haptic interface is distinct from other display devices because it is bi-directional; it is capable of both reading and writing input to and from a human user. Due to both the direct human interaction and bi-directionality there has been much ambiguity in describing and evaluating these devices, making evaluation and comparison difficult. The goal of this paper is to set out requirements and ...

We present a geometric theory of the performance of robot manipulators, applicable to systems with constraints, which may be non-holonomic. The performance is quanti ed by a geometrical object, the induced metric tensor, from which scalars may be constructed by invariant tensor operations to give performance measures. The measures thus de ned depend on the metric structure of con guration and w...

Moore’s Law suggests that the number of processing cores on a single chip increases exponentially. The future performance increases will be mainly extracted from thread-level parallelism exploited by multi/many-core processors (MCP). Therefore, it is necessary to find out how to build the MCP hardware and how to program the parallelism on such MCP. In this work, we intend to identity the key ar...

In this paper we explore the concept of instruments which are played by more than one person, and present two case studies. We designed, built and performed with Feedbørk, a two-player instrument comprising two iPads which form a video feedback loop, and Barrel, a nine-player instrument made up of eight Gametrak controllers fastened to a steel industrial barrel. By splitting the control of thes...
