Arrows are recognized as efficient visual elements in conveying location, direction, connection, and process because the shape is thought to have an immediate, common sense impact on viewers. However, the results of our prior quantitative study did not support the assumed effects of arrows in reading energy pyramid diagrams. The current study utili...

Drawing on cognitive theories of graphic comprehension and on systemic functional semiotics, the intention of this study is twofold: first, to examine the effects of image design on reading comprehension of science texts; second, to investigate the process of meaning-making when reading image and verbal text. An experiment was conducted to test the...

From a social semiotic perspective, image designs in science textbooks are inevitably influenced by the sociocultural context in which the books are produced. The learning environments of Australia and Taiwan vary greatly. Drawing on social semiotics and cognitive science, this study compares classificational images in Australian and Taiwanese juni...

Drawing on cognitive theories, this study intends to investigate the effects of explicit visual cues which have been proposed as a critical factor in facilitating understanding of biological images. Three diagrams from Taiwanese textbooks with implicit visual cues, involving the concepts of biological classification systems, fish taxonomy, and ener...

Raw data compression is an important step for high resolution SAR systems. This paper bases on two data compression methods, the 4 bit quantization and the 8 to 3 bit Block Adaptive Quantization (BAQ), which are widely used in spaceborne SAR, the evaluations are made on the Signal-to-Noise Ratio (SNR), the fidelity of the amplitude, and the vision...
