Review of Active Control of Flow-Induced Cavity Resonance

Abstract: A review of active control of flow-induced cavity oscillations is presented. This paper is motivated by two factors. First, the search for solutions to the practical problem of suppressing oscillations caused by flow over open cavities has generated significant interest in this area. Second, cavity oscillation control serves as a model problem in the growing multidisciplinary field of flow control. As such, we attempt to summarize recent activities in this area, with emphasis on experimental implementation of open- and closed-loop control approaches. In addition to describing successes, failures, and outstanding issues relevant to cavity oscillations, we highlight the characteristics of the various actuators, flow sensing and measurement, and control methodologies employed to date in order to emphasize the choices, challenges, and potential of flow control in this and other applications.

Solving differential equations with radial basis functions: multilevel methods and smoothing

Abstract: Some of the meshless radial basis function methods used for the numerical solution of partial differential equations are reviewed. In particular, the differences between globally and locally supported methods are discussed, and for locally supported methods the important role of smoothing within a multilevel framework is demonstrated. A possible connection between multigrid finite elements and multilevel radial basis function methods with smoothing is explored. Various numerical examples are also provided throughout the paper.

The Sixteen Personality Factor Questionnaire (16PF).

Abstract: The Sixteen Personality Factor Questionnaire (16PF) is a comprehensive measure of normalrange personality found to be effective in a variety of settings where an in-depth assessment of the whole person is needed. The 16PF traits, presented in Table 7.1, are the result of years of factor-analytic research focused on discovering the basic structural elements of personality (Cattell, R.B., 1957, 1973). In addition to discovering the sixteen normal-range personality traits for which the instrument is named, these researchers identified the five broad dimensions – a variant of the ‘Big Five’ factors (Cattell, R.B., 1957, 1970). From the beginning, Cattell proposed a multi-level, hierarchical structure of personality: the second-order global measures describe personality at a broader, conceptual level, while the more precise primary factors reveal the fine details and nuances that make each person unique, and are more powerful in predicting actual behavior. In addition, this factor-analytic structure includes a set of thirdorder factors, also discussed in this chapter. Due to its scientific origins, the 16PF Questionnaire has a long history of empirical research and is embedded in a well-established theory of individual differences. This questionnaire’s extensive body of research stretches back over half a century, providing evidence of its utility in clinical, counseling, industrial-organizational, educational, and research settings (Cattell, R.B. et al., 1970; H.E.P. Cattell and Schuerger, 2003; Conn and Rieke, 1994; Krug and Johns, 1990; Russell and Karol, 2002). A conservative estimate of 16PF research since 1974 includes more than 2,000 publications (Hofer and Eber, 2002). Most studies have found the 16PF to be among the top five most commonly used normal-range instruments in both research and practice (Butcher and Rouse, 1996; Piotrowski and Zalewski, 1993; Watkins et al., 1995). The measure is also widely used internationally, and since its inception has been adapted into over 35 languages worldwide.

A Deborah number for diffusion in polymer‐solvent systems

Abstract: A Deborah number is introduced as a means of characterizing diffusional transport in amorphous polymer-solvent systems. Two types of temperature-penetrant concentration diagrams are constructed, and the various regions on these figures are identified by their Deborah number values. The utility of the diffusion Deborah number is demonstrated by using this dimensionless group to anticipate conditions under which thickness anomalies can be expected in sorption experiments for the atactic polystyrenepentane system.
