Hierarchical Domains for Decentralized Administration of Spatially-Aware RBAC Systems
Emerging models for context-aware role-based access control pose challenging requirements over policy administration. In this paper we address the issues raised by the decentraliz...

Hierarchical Implicit Surface Refinement
A novel method of hierarchical implicit modeling is presented, in which an implicit object is modeled by using a hierarchy of implicit surfaces. The hierarchy provides both layere...

Hierarchical Correctness Proofs for Distributed Algorithms
Abstract: We introduce the input-output automaton, a simple but powerful model of computation in asynchronous distributed networks. With this model we are able to construct modular...

Clustering Dynamic Textures with the Hierarchical EM Algorithm
The dynamic texture (DT) is a probabilistic generative model, defined over space and time, that represents a video as the output of a linear dynamical system (LDS). The DT model ...
