Teaching Microarchitecture Through Metaphors

Students traditionally learn microarchitecture by studying textual descriptions with diagrams but few analogies. Several popular textbooks on this topic introduce concepts such as pipelining and caching in the context of simple paper-only architectures. While this instructional style allows important concepts to be covered within a given class period, students have difficulty bridging the gap b...

Is Evoking Negative Meanings the Unique Feature of Adjective Metaphors? : Through the Comparison with Nominal Metaphors and Predicative Metaphors

Previous metaphor studies have paid much attention to nominal and predicative metaphors and little attention has been given to adjective metaphors. Although some studies have focused on adjective metaphors, they have only examined how the acceptability of adjective metaphors can be explained by the pairing of adjective modifier’s and head noun’s modalities and little attention has been given to...

Program Visualization through Visual Metaphors

Reasoning with visual metaphors

Research into visual reasoning up to now has focused on images that are literal depictions of their objects. I argue in this article that an important further mode of visual reasoning operates on images that depict objects metaphorically. Such images form part of the class of expressive symbols: they are found, for example, in allegorical representations in works of visual art, studied by icono...

Data Visualization through Graph Drawing

In this paper the problem of visualizing categorical multivariate data sets is considered. By representing the data as the adjacency matrix of an appropriately defined bipartite graph, the problem is transformed to one of graph drawing. A general graph drawing framework is introduced, the corresponding mathematical problem defined and an algorithmic approach for solving the necessary optimizati...
