In many neural systems anatomical motifs are present repeatedly, but despite their structural similarity they can serve very different tasks. A prime example for such a motif is the canonical microcircuit of six-layered neo-cortex, which is repeated across cortical areas, and is involved in a number of different tasks (e.g. sensory, cognitive, or motor tasks). This observation has spawned inter...

this study was based on the hypothesis that “ecotourism is an important instrument in sustainable rural development and ecologically-based landscape planning approaches which take the objectives of socio-economic development and nature conservation have an effective role in this issue”. for this purpose, the necessity of ecologically-based landscape planning approaches in the planning and imple...

The entropy and mutual information index are important concepts developed by Shannon in the context of information theory. They have been widely studied in the case of the multivariate normal distribution. We first extend these tools to the full symmetric class of multivariate elliptical distributions and then to the more flexible families of multivariate skew-elliptical distributions. We study...

The Internet and WEB pervasiveness are changing the landscape of several different areas ranging from information gathering/managing and commerce to software development, maintenance and evolution. Traditionally, phone-centric services, such as ordering of goods, maintenance/repair intervention requests and bug/defect reporting, are moving towards WEB-centric solutions. This paper proposes the ...

1 This paper is abridged and adapted from Nickerson, et al. in press. Specifically, only three of the problems presented to student designers are discussed here and an additive tree analysis of errors is added. Abstract Designers use sketches to offload memory and information processing and to promote discovery and inferences. Designers of information systems depend on topological connectivity ...
