Abstract The main motivation for “hierarchical biomechanics” is that the wide variability of mechanical properties encountered at macroscopic scale may be traced back to just a few “universal” or invariant elementary components sufficiently small (such as collagen, elastin, and water in case soft tissues; complemented by hydroxyapatite hard “mineralized” tissues such bone), nano-and microstruct...

The seemingly infinite diversity of the natural world arises from a relatively small set of coherent rules, such as the laws of physics or chemistry. We conjecture that these rules give rise to regularities that can be discovered through primarily unsupervised experiences and represented as abstract concepts. If such representations are compositional and hierarchical, they can be recombined int...

Components have become a widely accepted concept used in building large-scale applications. Although the concept of a component is not really new, it is generally not clear how to deal with the component abstraction at runtime. This manifests in the fact that nowadays component systems can be basically divided (a) to those being rich in advanced features (e.g., hierarchical components, software...

The natural world is infinitely diverse, yet this diversity arises from a relatively small set of coherent properties and rules, such as the laws of physics or chemistry. We conjecture that biological intelligent systems are able to survive within their diverse environments by discovering the regularities that arise from these rules primarily through unsupervised experiences, and representing t...

Learning hierarchical concepts is a central problem in cognitive science. This paper explores the Nearest-Merge algorithm for creating hierarchical clusters that can handle both feature-based and relational information, building on the SAGE model of analogical generalization. We describe its results on three data sets, showing that it provides reasonable fits with human data and comparable resu...

The transverse compression and shear collapse mechanisms of a second order, hierarchical corrugated truss structure have been analyzed. The two competing collapse modes of a first order corrugated truss are elastic buckling or plastic yielding of the truss members. In second order trusses, elastic buckling and yielding of the larger and smaller struts, shear buckling of the larger struts, and w...

The Metathesaurus of the UMLS was created by integrating various source terminologies. The inter-concept relationships were either integrated into the UMLS from the source terminologies or specially generated. Due to the extensive size and inherent complexity of the Metathesaurus, the accidental omission of some hierarchical relationships was inevitable. We present a recursive procedure which a...

Flexible Machining Cells (FMC) have become very popular in many manufacturing environments due to the reduction in set-up down-time using off-line set-up. A similar procedure is not yet available for assembly cells. This arises from the need for accurate positioning of parts from bulk storage containers prior to assembly. Complex fixturing and orientating devices are often required for correct ...
