To interpret information visualizations, observers must determine how visual features map onto concepts. First and foremost, this ability depends on perceptual discriminability; be able to see the difference between different colors for those communicate meanings. However, visualizations also semantic discriminability, degree which can infer a unique mapping concepts, based concepts alone (i.e....

Complexity of software systems has significantly grown with social dependence on computer system, especially for mobile and internet. So we present component-based communication protocol architecture. In this architecture, Component Development Platform (CDP) is the kernel software. CDP is one of the rapid communication components’ development tools. It is the collection of views and plug-ins t...

A major difficulty in enterprise computing is the modeling of complex application topologies consisting of numerous individual components and their relationships. Especially in the context of cloud computing, the Topology and Orchestration Specification for Cloud Applications (TOSCA) has been proposed recently for standardization to tackle this issue. However, TOSCA currently lacks a well-defin...

The purpose of this study is to investigate the effect of the curved display on visual performance and user experience. Eye-tracking technique and self-report were adopted to assess the visual performance when watching multimedia on the curved display. For visual examination, two curvatures were chosen: flat and curved with a radius equal to 4200 mm. A series of 12 clips were presented, consist...
