In this work, we present a demonstration of a visual interactive tool called ESSAVis that helps different engineers in collaborating together for understanding the failure mechanisms in complex embedded systems. ESSAVis provides a 2Dplus3D visual user interface that integrates intuitively between different data sets related with embedded systems failure(More)
Maintaining modern embedded systems requires close collaboration between engineers who designed them and engineers who analyzed possible failures in such systems in order to avoid any possible hazard. In this work, we present a collaborative visual platform that supports the safety analysis process of such systems in a collaborative manner. The platform(More)
In this paper, we present an algorithm, called CluE (The Cluster Expander of Compound Graphs), that expands cluster nodes in compound graphs. CluE was designed to work with multiple layout algorithms (e.g., orthogonal layout algorithm, Sugyima layout algorithm, etc.). It keeps the unexpanded nodes in their relative layers with slight changes in their(More)
Recently, we witness a high usage of social media platforms for different purposes, from contacting with friends and colleagues to raising voice for different causes. Many times, on such social media platforms people are also interested to see and analyze the connections not only with their connected people but also the connections between these connected(More)
In tabletop-supported collaborative environments, direct viewing or accessing to all parts of the screen is not possible in many cases. This could affect the performance of team members in executing the common collaborative tasks. Targeting this concern, we developed the ViZCom (Viewing, Zooming and Commenting) framework that enables the team members to(More)
Modern embedded systems contain complex structures, as they are composed of many subsystems. Maintaining such systems requires collaboration between the engineers who designed them and the engineers who analyzed the failures in them. In this paper we present our proposed visual platform ESSAVis, a 2Dplus3D environment, to help both kinds of engineers in(More)
In this paper, we present a framework, called Embedded-System Safety Aspects Visualization (ESSAVis), that is a system prototype designed to analyze the safety aspects of embedded systems. The ESSAVis prototype provides a 3D environment that aids in detecting infected components in the hardware of the target embedded system. The prototype also provides an(More)
