De Jong,David Peter.MS. ,Purdue University.Nuy1978.Evaluation of Access Paths in a Relational Database System.Najor Professor: S. B. Yao. The motivation for and concepts of a relational database organization are briefly reviewed, and a ~eneral model of acc~ss paths for a relational database is described. As a tool for access path desicn and selection a series of equations are developed for the ...

Three experiments tested whether the Implicit Association Test (IAT) reflects general knowledge, or whether it is sensitive to personally endorsed attitudes. In Experiment 1, participants learned to associate positive or negative attributes with two novel groups. Participants in one condition were told that the attributes accurately described the groups; in a second condition, they were told th...

This article covers a tracking appoach for multiple simultaneously flying animals. The idea is to constraint the tracking to the physically possible space without any knowledge of the scene. Accordingly, we propose to use a naively made trajectory dataset as a base to track the targets into the possible space rather than the probable space. First, a trajectory database is computed under weak as...

In this paper, an automatic pre–crash collision avoidance strategy for cars is presented. It produces a collision avoidance manoeuvre, if feasible, or, otherwise, an emergency braking to reduce the energy at the impact. The manoeuvre is generated relying on the use of sliding mode control. The performances of the proposed collision avoidance system are tested on a scaled radio–controlled car an...

A large number of papers and reports that have been published after the Napoli RPC97 workshop show an impressive progress in improving the RPC performances and extending their use to new "elds of application. This talk is an attempt to summarize the state of the art at the beginning of the present workshop as an introduction to the new results that will be presented. A discussion about the scal...

This paper shows that, even if volatility is accurately predicted by correctly specified GARCH models, however such predictions are not very useful for traders when the conditional volatility does not vary "enough" over time, being therefore quite close to the unconditional one. It is shown that a low R in the Mincer-Zarnowitz regression implies flat (although correctly predicted) volatility, a...

This paper examines the relationship between strategy and Total Quality Management (TQM) implementation, as well as the impact of the adaptation of both to organizational performance. We have used the emphasis on cost leadership, differentiation on marketing and differentiation on innovation as strategic dimensions to develop four great strategic configurations. The degrees of implementation of...

Software performance prediction methods are typically validated by taking an appropriate software system, performing both performance predictions and performance measurements for that system, and comparing the results. The validation includes manual actions, which makes it feasible only for a small number of systems. To significantly increase the number of systems on which software performance ...
