Statically parsing shell scripts is, due to various peculiarities of the shell language, a challenge. One of the difficulties is that the shell language is designed to be executed by intertwining reading chunks of syntax with semantic actions. We have analyzed a corpus of 31.521 POSIX shell scripts occurring as maintainer scripts in the Debian GNU/Linux distribution. Our parser, which makes use...

This paper reports on the generation of coherent multimodal output of an embodied conversational character in a 3D game setting. In our implementation, we employ a hierarchical two-tiered approach that supports the designer in creating agent behaviors through scripts. Lower-level scripts define sets of both elementary animations and custom animations, along with their temporal duration. At a hi...

Optical Character Recognition (OCR) is one of the challenging areas of pattern recognition. It gained popularity among the research community due to its vast application potentials. Extensive research has been done on OCR evidenced by a large number of research articles published in the literature during the last few decades. Most of the research works reported in this area are for Roman, Chine...

Shells, as command interpreters, are the classical way for humans to interact with computing systems, and modern shell features have extended this basic functionality with higher-level programming language constructs. Although implementing compilation in these shell languages is generally unprofitable and intractable, many advantages, such as isolation, filesystem abstraction, security, portabi...

Using scripts to automate common administrative tasks is a ubiquitous practice. Powerful scripting languages and approaches support seemingly 'efficient' scripting practices that actually compromise the robustness of our scripts, as well as indirectly detracting from the stability and maturity of our support infrastructure. This is especially true for scripts that automate complex interactive p...

The use of Web augmentation techniques has an impact on tasks of owners of Web sites, developers of scripts and end-users. Because the Web sites can be modified by external scripts, their owners might lose control about how Web site contents are delivered. To prevent this, they might be tempted to modify the structure of Web pages thus making harder to execute external scripts. However, communi...

Objective. Expert clinical teachers in medicine use teaching scripts. The aim of this study was to determine whether pediatricians also use common components of teaching scripts. Methods. Seventy-three pediatric clerkship directors identified anticipated errors and teaching points in response to two short vignettes. The content analysis of responses, which we completed, was analyzed by rank and...

In this paper we will continue the study of p-closed spaces. This class of spaces is strictly placed between the class of strongly compact spaces and the class of quasi-Hclosed spaces. We will provide new characterizations of p-closed spaces and investigate their relationships with some other classes of topological spaces.

What should and should not be considered an affordance is still an open issue. At the 2002 North American meeting of the International Society for Ecological Psychology, a symposium was held concerning this topic. The articles in this special issue are expanded versions of the papers presented at that symposium. To set the stage for those discussions, this article presents an analysis of the ev...

Abstract Story segmentation is an important problem in multimedia indexing and retrieval and includes detection of commercials as one of its component problems. Commercials appear regularly in television data and are usually treated as noise. Hence, filtering of commercials is an important task. This paper presents a system that detects and filters commercials from broadcast news data. While pr...
