Application Specific Performance Measurements of Image Compression Codecs

by Thomas Richter
"... Traditionally, the performance of a image compression codec is measured by its rate-distortion curve, where a distortion metric measures the fitness of the reconstructed image for a particular purpose. However, metrics employed here address the needs of professional photography only partially: Image ..."

The Paradyn Parallel Performance Measurement Tools

by Barton P. Miller, Mark D. Callaghan, Jonathan M. Cargille, Jeffrey K. Hollingsworth, R. Bruce Irvin , Karen L. Karavanic, Krishna Kunchithapadam, Tia Newhall - IEEE COMPUTER , 1995
"... Paradyn is a performance measurement tool for parallel and distributed programs. Paradyn uses several novel technologies so that it scales to long running programs (hours or days) and large (thousand node) systems, and automates much of the search for performance bottlenecks. It can provide precise ..."

Performance of optical flow techniques

by J. L. Barron, D. J. Fleet, S. S. Beauchemin - INTERNATIONAL JOURNAL OF COMPUTER VISION , 1994
"... While different optical flow techniques continue to appear, there has been a lack of quantitative evaluation of existing methods. For a common set of real and synthetic image sequences, we report the results of a number of regularly cited optical flow techniques, including instances of differential, ..."

, matching, energy-based and phase-based methods. Our comparisons are primarily empirical, and concentrate on the accuracy, reliability and density of the velocity measurements; they show that performance can differ significantly among the techniques we implemented.

An inventory for measuring depression

by A. T. Beck, C. H. Ward, J. Mock M. D - Archives of General Psychiatry , 1961
"... The difficulties inherent in obtaining con-sistent and adequate diagnoses for the pur-poses of research and therapy have been pointed out by a number of authors. Pasamanick12 in a recent article viewed the low interclinician agreement on diagnosis as an indictment of the present state of psychiatry ..."

variety of paper-and-pencil tests have been devised for the purpose of measuring specific personality traits; for example, the Depression-Elation Test, de-vised by Jasper in 1930. This report describes the development of an instrument designed to measure the behavioral manifestations of depression

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,

by ] Richard Hackman , Grec R Oldham , 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

Also, Hackman and Lawler found that a number of dependent measures were moderated as MOTIVATION THROUGH DESIGN OF WORK 255 predicted by growth need strength: That is, employees with high measured needs for growth

The performance of mutual funds in the period 1945-1964

by Michael C. Jensen - JOURNAL OF FINANCE , 1968
"... In this paper I derive a risk-adjusted measure of portfolio performance (now known as "Jensen's Alpha") that estimates how much a manager's forecasting ability contributes to the fund's returns. The measure is based on the theory of the pricing of capital assets by Sharpe (1 ..."

Exceptional Exporter Performance: Cause, Effect or Both

by Andrew B. Bernard, J. Bradford Jensen - Journal of International Economics , 1999
"... A growing body of empirical work has documented the superior performance characteristics of exporting plants and firms relative to non-exporters. Employment, shipments, wages, productivity and capital intensity are all higher at exporters at any given moment. This paper asks whether good firms becom ..."

A statistical interpretation of term specificity and its application in retrieval

by Karen Spärck Jones - Journal of Documentation , 1972
"... Abstract: The exhaustivity of document descriptions and the specificity of index terms are usually regarded as independent. It is suggested that specificity should be interpreted statistically, as a function of term use rather than of term meaning. The effects on retrieval of variations in term spec ..."

Tobins Q, corporate diversification and firm performance

by Larry H. P. Lang, René M. Stulz , 1993
"... In this paper, we show that Tobin's q and firm diversification are negatively related. This negative relation holds for different diversification measures and when we control for other known determinants of q. We show further that diversified firms have lower q's than equivalent portfolios ..."

In 590 for-profit and nonprofit firms from the National Organizations Survey, we found positive associations between human resource management (HRM) practices, such as training and staffing selectivity, and perceptual firm performance measures. Results also suggest methodological issues for conside ..."
