We have developed a technique for authoring a nonlinear plot and for managing a story according to the plot in an interactive story-based virtual reality application. The technique exploits Petri Nets that alter reactive plans controlling individual actors. Its main advantage is that it allows for iterative design and copes with large virtual worlds inhabited with tens of actors. In this paper,...

This paper is to estimate the optimum plot size with the shape for field research experiments on paddy yield trial considering the effect of plot size on variability in yield of crop as well as studying the coefficients of variation of different plot sizes and shapes of plots. The maximum curvature technique and comparable variance methods were exercised to estimate optimum plot size and shape ...

The paper reports about authors’ investigation of applicability of a well-known technique of visualization of multivariate data, parallel coordinates plot, to different kinds of tasks. Some new methods of transformation of parallel coordinates plots are suggested. However, the primary aim of the authors is “to link tools to tasks”, i.e. to explicitly define the tasks that can be appropriately s...

In order to summarize a story, it is necessary to access a high level analysis of the story that highlights its central concepts. A technique of memory representation based on plot units appears to provide a rich foundation for such an analysis. Plot units are conceptual structures that overlap with each other when a narrative is cohesive. When overlapping intersections between plot units are i...

The paper addresses the possibility to replace cluttered multi-group scatter-plots with augmented convex hull plots. By replacing scatter-plot points with convex hulls, space is gained for visualization of descriptive statistics with error bars or confidence ellipses within the convex hulls. An informative addition to the plot is calculation of the area of convex hull divided by corresponding g...

Because of the importance of damage detection in manufacturing systems and other areas, many fault detection methods have been developed that are based on a vibration signal. Little work, however, has been reported in the literature on using a recurrence plot method to analyze the vibration signal for damage detection. In this paper, we develop a recurrence plot based fault detection method by ...

A new algorithm for the estimation of probability density functions has been considered in the paper. This founds a large number of applications in the context of statistical signal processing problems, such as detection, estimation, filtering or pattern recognition and classification. The proposed approach relies on the QQ-plot technique. The estimates of the first and second order statistics ...
