The possibility of achieving experimentally controlled, non-vocal acoustic production in non-human primates is a key step to enable the testing of a number of hypotheses on primate behavior and cognition. However, no device or solution is currently available, with the use of sensors in non-human animals being almost exclusively devoted to applications in food industry and animal surveillance. S...

Whereas rational and formal reasoning should be devoid of contradictions, people must often handle conflicting perspectives in everyday contexts. The present article is based on empirical studies of conflicting prototypes of forest in Sweden and Canada. Conflicting prototypes of forest correspond to different values and actions in real environments. The empirical data demonstrate how metaphoric...

A prototype reduction algorithm is proposed which simultaneous train both a reduced set of prototypes and a suitable local metric for these prototypes. Starting with an initial selection of a small number of prototypes, it iteratively adjusts both the position (features) of these prototypes and the corresponding local-metric weights. The resulting prototypes/metric combination minimizes a suita...

Canonical abstract prototypes are an innovative means for specifying and exploring visual and interaction design ideas. Intermediate between abstract task models and realistic or representational prototypes, canonical abstract prototypes provide designers with a standardized vocabulary for expre ssing visual and interaction designs independent of details of appearance and behavior. This common ...

Abstract 3D printing is a widely used technology for automating the fabrication of prototypes. The benefits are wide reaching, and include low required expertise, accurate geometric form processibility many materials. However, production certain forms – especially large can be slow. From review sub-systems, hotend commonly found to limiting factor. To improve this, modified nozzle design consid...

The expressiveness and complexity of several active database prototypes are formally studied. First, a generic framework for the spec-iication of active databases is developed. This factors out the common aspects of the prototypes considered, and allows studying various active database features independently of any speciic prototype. Furthermore, each of the prototypes can be speciied by specia...
