Adaptive hierarchical structures

1995
The construction of a hierarchical system to distinguish classes of patterns can be improved by the combination of a dynamical elastic matching with a time dependent image resolution. Using the elastic matching as a preprocessing for synergetic computers one achieves an invariant perception by means of arbitrary spatial transformations.

The Hierarchical Structure

2021
This chapter addresses a fundamental issue in Multi-Criteria Decision-Making (MCDM) problems consisting in how to model complex scenarios. It starts by defining complex scenarios and examines the hierarchical structure followed by the AHP method, considered not suitable for modelling them, as well as their relationship with the decision-maker.

On dynamic crushing behavior of honeycomb-like hierarchical structures with perforated walls: Experimental and numerical investigations

International Journal of Impact Engineering, 2020
Hierarchical structures have the potential advantage of enhancing their energy absorption capabilities. Honeycomb-like hierarchical structures are developed and manufactured by perforating on the cell walls consisting of single thickness inclined walls ...

The hierarchic structure of fears

Behaviour Research and Therapy, 1998
Contemporary theories of fears (and phobias) suggest two kinds of etiologic factors; those common to all fears (factors influencing fear-proneness) and factors specific to particular fears (e.g. specific learning experiences). There also may be etiologic factors of intermediate specificity; factors common to some but not all fears.

Composing Hierarchically Structured Images

Computer Graphics Forum, 1992
AbstractThis paper begins by examining the ‘classical’ raster‐based composition model, establishing its weakness, and developing a new composition algebra based on line drawing. It then examines the role of composition in the Hierarchical Display Model, demonstrates that the forms of composition assumed in this model are inadequate to deal correctly ...
