Techniques that traditionally have been useful for retrieving same domain analogies from small single use knowledge bases such as spreading activation and indexing on selected features are inadequate for retrieving cross domain analogies from large multi use knowledge bases In this paper we describe Knowledge Directed Spreading Activation KDSA a new method for retriev ing analogies in a large s...

In naturally occurring speech and gesture, meaning occurs organized and distributed across the modalities in different ways. The underlying cognitive processes are largely unexplored. We propose a model based on activation spreading within dynamically shaped multimodal memories, in which coordination arises from the interplay of visuo-spatial and linguistically shaped representations under give...

  Spreading and coating of nano and micro droplets on solid surfaces is important in a wide variety of applications including plasma spray coating, ink jet printing, DNA synthesis and etc. In spraying processes, most of droplets collide obliquely to the surface. The purpose of this article is to study the distribution of nano and micro droplets spreading when droplets impact at an oblique a...

Driving through floodwater is a significant cause of flood-related injury and mortality, opportunities exist to embed safe driving messages regarding floodwaters novice drivers in graduated driver licensing schemes. To inform future educational efforts, we investigated the beliefs attitudes Australian learner about avoiding floodwaters. Methods: The study adopted cross-sectional correlational d...

Transgene spreading is a major concern in cultivating genetically modified (GM) corn. Cross-pollination may cause the spread of transgenes from GM cornfields to conventional fields. Occasionally, seed lot contamination, volunteers, mixing during sowing, harvest, and trade can also lead to transgene escape. Obviously, new biological confinement technologies are highly desired to mitigate transge...
