The reinforcement learning problem can be decomposed into two parallel types of inference: (i) estimating the parameters of a model for the underlying process; (ii) determining behavior which maximizes return under the estimated model. Following Dearden, Friedman and Andre (1999), it is proposed that the learning process estimates online the full posterior distribution over models. To determine...

Beyond the goal of refining system design to the needs and tastes of users, user evaluation of interactive music systems offers a method of examining the nature of musical creativity as understood by its human practitioners. In the case of improvising music systems, user study and evaluation of a system’s ability to improvise may be useful in the ethnomusicological study of musical interaction ...

In 1993, a new beryllium bearing bulk metallic glass with the nominal composition of Zr41.25Ti13.75Cu12.5Ni10Be22.5 was discovered at Caltech. This metallic glass can be cast as cylindrical rods as large as 16 mm in diameter, which permitted specimens to be fabricated with geometries suitable for dynamic testing. For the first time, the dynamic compressive yield behavior of a metallic glass was...

The use of a single pass/fail threshold for IDDQ testing is unworkable as chip background currents increase to the point where they exceed many defect currents. This paper describes a method of using " current signatures " which uses only simple comparisons on the tester, and which automatically scales with process variations which give a wide range of background currents. Dynamic thresholds ar...

In this paper we report on a public display where the audience is able to interact not only with visuals, but also with music. The interaction with music in a public setting involves some challenges, such as that passers-by as ‘novice users’ engage only momentarily with public displays and often don’t have any musical knowledge. We present a system that allows users to create harmonic melodies ...

As it is known, on the political scene the success of a speech can be measured by the degree in which the speaker is able to change attitudes, opinions, feelings and political beliefs in his auditorium. We suggest a range of analysis tools, all belonging to semiotics, from lexical-semantic, to syntactical and rhetorical, that integrated in the exploratory panoply of discursive weapons of a poli...

In this paper, an Economic Dispatch (ED) model is developed for the system consisting of both thermal generators and wind turbines. The inclusion of a significant amount of wind energy into power systems has resulted in additional constraints on ED to accommodate the intermittent nature of the output. The probability of stochastic wind power based on the Weibull probability density function is ...

This paper presents an overview of manufacturing, static/dynamic test and validation work carried out on composite rail vehicle structures. Two case studies, detailing the development and experimental validation of a composite bodied people mover and a foam core composite roof for a regional train are presented, demonstrating new and novel applications of composite materials within the rail ind...

effect of small al additions, from 0.14% to 0.31% ai, on the hot deformation behavior of low carbon steels containing 1%cu-1.2%mn was investigated in the temperature range of 750-800•c over the strain rate range of 1o.3.1o.1s•1 by a hot compression testing machine. the flow curves obtained, exhibited typical characteristics of dynamic recovery type of softening mechanism, and the critical strai...

The software industry favors dynamic testing over static analysis of software, because traditional static software analysis techniques do not adequately balance automation, precision and scalability. Recently several researchers have combined static and dynamic techniques to overcome these problems. Undergoing efforts include concolic execution, testing-based correctness prove, execution driven...
