Numerical modelling of a discontinuous medium has gained much popularity in recent decades. The combined finite-discrete element method (FEM/DEM) is a state-of-the-art numerical modelling technique pioneered in the mid-1990s. Y2D is a robust two-dimensional FEM/DEM research code developed by Munjiza in 2004. The major limitations of this code are (1) the lack of a graphical user interface (GUI)...

Two main options exist to implement an Internet front-end for an application with a graphical user interface (GUI). The first is to "hard-code" a remote interface specifically for the application and distribute it to client computers. The problem with this approach is the inflexibility of the resulting interface. An alternative approach that minimises the need for client re-distribution is to p...

This framework will also allow them to factorize the structure common to all their documents into classes, and will free them from all other design considerations. Moreover, OPTIM allows authors to insert interactive parts into their documents without any GUI programming skills. They only have to provide the computational code that supplies the numerical values to be displayed by the GUI, and t...

In the context of an e↵ort to develop methodologies to support the evaluation of interactive system, this paper investigates an approach to detect graphical user interface bad smells. Our approach consists in detecting user interface bad smells through model-based reverse engineering from source code. Models are used to define which widgets are present in the interface, when can particular grap...

Testing a GUI’s visual behavior typically requires human testers to interact with the GUI and to observe whether the expected results of interaction are presented. This paper presents a new approach to GUI testing using computer vision for testers to automate their tasks. Testers can write a visual test script that uses images to specify which GUI components to interact with and what visual fee...

Icons, widely used in computer programs, are part of the Graphical User Interface (GUI). They facilitate computer use regardless of users’ level of expertise. The authors report the results of a study focused on measuring performance of computer users in correctly and quickly associating toolbar icons and the action they represent in GUI. The study aimed to investigate the relationships between...

Modern computing systems exploit graphical user interfaces for interaction with users. As a result, introductory computer science courses must begin to teach the principles underlying such interfaces. This paper presents an approach to graphical user interface implementation that is simple enough for beginning students to understand, yet rich enough to demonstrate many important concepts and tr...

This paper introduces JavaBean Calculation Engines (JBCEs), a procedure for deploying algorithms in a standard JavaBean framework. For the algorithm developer, JBCEs are a finishing point for deploying an algorithm as a “qualified product”. For the GUI developer, JBCEs shield internal computations behind a JavaBean interface. By standardising the interface between computational and GUI code, JB...

This paper focuses on the practical aspects of building a Domain-Specific solution for families of thick-client GUI components. The components lack business-logic, they are parts of thick-client applications and are built to be used through well-defined data oriented interfaces. We’ve observed that with such GUI components it is not always possible to keep the generators simple. Generating the ...
