Multiple hierarchical models of representative democracies in which, for instance, voters elect county representatives, county representatives elect district representatives, district representatives elect state representatives and state representatives a president, reduces the number of electors a representative is answerable for, and therefore, considering each level separately, these models ...

We propose a hierarchical simulation methodology to assist application development on System-on-Chip architectures. Hierarchical simulation involves simulation of a SoC based system at different levels of abstraction. Thus, it enables a system designer to exploit simulation speed vs. accuracy of results trade-offs. Vertical simulation is a special case of hierarchical simulation, where a feedba...

We consider the creation conditions of diverse hierarchical trees both analytically and numerically. A connection between the probabilities to create hierarchical levels and the probability to associate these levels into a united structure is studied. We argue that a consistent probabilistic picture requires the use of deformed algebra. Our consideration is based on the study of the main types ...

The recent introduction of phylochips that contain molecular probes facilitates environmental microbial identification in a single experiment without previous cultivation. A set of probes recognizing species at different taxonomic levels is denoted as a hierarchical set. Application of hierarchical probe sets on a DNA microarray allows the assessment of biodiversity with different resolutions. ...

Paired hierarchical visualizations (PairTrees) integrate treemaps, node-link diagrams, choropleth maps and other information visualization techniques to support exploration of hierarchical data sets at multiple levels of abstraction (Kules, Shneiderman et al., in press). Coordinated visualizations are an effective way to support exploratory data analysis of multidimensional data sets. Hierarchi...

A hierarchical MEMS synthesis and optimization architecture has been developed for MEMS design automation. The architecture integrates an object-oriented component library with a MEMS simulation tool and two levels of optimization: global genetic algorithms and local gradient-based refinement. An object-oriented data structure is used to represent hierarchical levels of elements in the design l...

The topic of this contribution is the synthesis of hierarchical control systems for hybrid problems. We outline a method that is based on a hierarchy of models describing the plant at various levels of abstraction and a decomposition of the overall specification. The proposed method captures several key requirements for hierarchical control: it includes the notion of information aggregation bet...

An essential requirement for the representation of functional patterns in complex neural networks, such as the mammalian cerebral cortex, is the existence of stable regimes of network activation, typically arising from a limited parameter range. In this range of limited sustained activity (LSA), the activity of neural populations in the network persists between the extremes of either quickly dy...
