We have developed two computer algebra systems (CAS) written in Java [9, 12]. The Java libraries can be used as any of the numerous other Java library packages. For the use-case of interactively entering and manipulating mathematical expressions there is a need of a scripting front-end for our libraries. Most other CAS invent and implement their own scripting interface for this purpose. We, how...

Scripting languages such as Python and Tcl have become a powerful tool for the construction of exible scienti c software because they provide scientists with an interpreted problem solving environment and they form a modular framework for controlling software components written in C,C++, and Fortran. However, a common problem faced by the developers of a scripted scienti c application is that o...

Domain-Independent Models are mainly used for documentation purposes and are most of the time too generic to be directly executed, even by code generation. Domain-Specific Models can sometimes be executed, but their scope is too specific to be reused for other purposes. We have developed a mechanism that allows the creation of modeling languages that will be directly executed into software appl...

This paper presents the three scripting commands and main functionalities of a novel character animation environment called CHASE. CHASE was developed for enabling inexperienced programmers, animators, artists, and students to animate in meaningful ways virtual reality characters. This is achieved by scripting simple commands within CHASE. The commands identified, which are associated with simp...

We have developed two computer algebra systems, meditor [9] and JAS [12]. These CAS systems are available as Java libraries. For the use-case of interactively entering and manipulating mathematical expressions, there is a need of a scripting front-end for our libraries. Most other CAS invent and implement their own scripting interface for this purpose. We, however, do not want to reinvent the w...

Domain-Independent Models are mainly used for documentation purposes and are most of the time too complex to be directly executed, even by code generation. Domain-Specific Models can sometimes be executed, but their scope is too specific to be reused for other purposes. We propose to develop a mechanism that allows the creation of modeling languages that will be directly executed into software ...

Since 2002, over half of reported cyber vulnerabilities are caused by input validation vulnerabilities . Over 50 % of input validation vulnerabilities were cross-site scripting and SQL injection vulnerabilities in 2006, based on the (US) National Vulnerability Database. Techniques to mitigate cross-site scripting and SQL injection vulnerabilities have been proposed. However, applying those tech...
