After a very gradual 20 year development, the discipline of scientific visualization was given form and focus (and its name) by the seminal 1987 report, "Visualization in Scientific Computing". Since then the methods, means, and results of scientific visualization have grown and diversified so that now one can travel from SIGGRAPH to Visualization ...
This paper describes a low level hierarchical framework for composition of multimedia documents that is designed to support the types of analysis, error checking, and synthesis techniques needed for rich user support in a high-level authoring system. This framework supports flexible synchronization and flow control primitives as well as a range of ...
In most proposed architectures for Video-On-Demand (VOD) systems, the customers are serviced individually by allocating and dedicating a trans- mission channel and a set of video server resources to each customer. This approach leads to an expensive-to-operate, non-scalable system. We consider a VOD system that uses multicast delivery to service mu...
Advances in networking, visualization and parallel computing signal the end of the days of batch-mode processing for computationally intensive applications. The ability to control and interact with these applications in real-time offers both opportunities and challenges. This paper examines two computationally intensive scientific applications and ...
Vast amounts of attention and resources have recently been devoted towards the World Wide Web (WWW) [Berners-Lee 94], but relatively little research has been conducted that examines Web usage and societal implications. With the goals of understanding the Web user population and promoting the Web as a viable surveying medium, GVU's WWW User Surveys ...
Interactive (Synchronous) Groupware encompasses a wide range of applications, like collaborative whiteboards, text editors, engineering CAD (Computer Aided Design), Distributed Virtual Environments, and multi-player games. A very critical requirement for all these applications is the need to share data, which can be replicated to provide better res...
The development of an image-processing (IP) application is a complex activity, which can be greatly alleviated by user-friendly graphical programming environments. The major objective of the work described in this paper is to help IP experts reuse parts of their applications. A first step towards knowledge reuse has been to propose a suitable repre...
Interactive Collaborative applications, such as distributed virtual environments, collaborative CAD and multi-player games, are enabled by the data being shared across distributed users. The need to support such applications in a wide-area environment, and at the same time provide fast response to users, motivates replication of this shared data. T...
Cet article présente différentes manipulations sur des graphiques, réalisées avec SAS Insight.
La façon dont se distribue une variable est représentée sous forme d'un histogramme ou d'un Box Plot si la variable en question est une variable d'intervalle, par un Bar Chart ou un Mosaic Plot s'il s'agit d'une variable nominale. Le Line Plot et le Scat...
La boîte à moustaches une traduction de Box & Whiskers Plot, est une invention de TUKEY (1977) pour représenter schématiquement une distribution. Cette représentation graphique peut être un moyen pour approcher les concepts abstraits de la statistique. Dans cet article nous détaillons comment lire et interpréter des boîtes à moustaches.
