Visualizing the artifacts of a software system graphically has proven to improve the cognitive strategies and understanding of the subject system by programmers. This is more crucial when they need to maintain a software system with out-dated documentation or without system documentation at all. Many tools have emerged and they predominantly consist of a reverse engineering environment and a viewer to visualize software artifacts such as in the form of graphs. The tools also grant structural redocumentation of existing software system but they do not directly utilize document-like software visualization in their approaches. We propose DocLike modularized graph (DMG) method that represents the software architectures of a reverse engineered subject system graphically in a modularized and standardized document-like manner. To realize this method, we have built a prototype tool called DocLike Viewer that enables a user to redocument, visualize and comprehend a subject system written in C language that is parsed by an existing parser. From the experiment conducted we found that our method managed to statistically improve cognition of a subject system in terms of productivity and quality to solve certain types of maintenance tasks.
This paper surveys and investigates the strengths and weaknesses of a number of recent approaches to advanced workflow modelling. Rather than inventing just another workflow language, we briefly describe recent workfl...

The scale of software on digital AV appliances that handle large-volume multichannel digital data has been increased by the GUIs (graphical user interfaces) loaded on them in recent years. In addition, the GUIs of AV ...

Selected mapping (SLM) generates a set of independent signals from an information sequence and transmits the signal with minimum peak-to-average power ratio (PAR). To recover data, the receiver is sent critical side information (SI) about the generation process. In this paper, a novel blind detection algorithm is developed for coded orthogonal frequency division multiplexing (OFDM) and SLM. The blind SLM algorithm performs well in both AWGN and fading channels in the presence of amplifier non-linearities.
