Ranged name retrieval: Design and evaluation of a flexible data retrieval approach for ICN

In Information-Centric Networking (ICN), applications request data based on the (exact) name of the data of interest. This poses a challenge for a growing number of applications, which do not know a priori the full name of a data object they seek, or do not necessarily need a specific data object, but are interested in a certain scope (e.g. the...

Using hierarchical cluster models to systematically identify groups of jobs with similar occupational questionnaire response patterns to assist rule-based expert exposure assessment in population-based studies

Objectives: Rule-based expert exposure assessment based on questionnaire response patterns in population-based studies improves the transparency of the decisions. The number of unique response patterns, however, can be nearly equal to the number of jobs. An expert may reduce the number of patterns that need assessment using expert opinion, but...

Construction and minimality of coordinated linear systems

Coordinated linear systems are a particular class of hierarchical systems with a top-to-bottom information structure, consisting of a coordinator system and two or more subsystems. This paper deals with the construction and minimality of coordinated linear systems. Construction procedures are given to transform unstructured or interconnected...

Vertical emission profiles for Europe based on plume rise calculations

The vertical allocation of emissions has a major impact on results of Chemistry Transport Models. However, in Europe it is still common to use fixed vertical profiles based on rough estimates to determine the emission height of point sources. This publication introduces a set of new vertical profiles for the use in chemistry transport modeling...

A four-tiered hierarchy in a converged fixed-mobile architecture, enabling personal networks

We present a new way of capturing the future technical infrastructure of a converged fixed-mobile infrastructure by means of a four-tiered hierarchy of one fixed and three different mobile and wireless (access) layers. With such a view, the current range of heterogeneous interconnected public and private networks can be easily modelled as a...

The relationship between information prioritization and visual distinctness in two progressive image transmission schemes

The goal of this paper is to analyze the relation between the visual distinctness and the priority assigned to the information in two di2erent progressive transmission schemes: the Set Partitioning in Hierarchical Trees (SPIHT) and the Rational Embedded Wavelet Image Coding (REWIC). SPIHT assigns priority based on the mean squared-error (MSE)...

Image segmentation by connectivity preserving relinking in hierarchical graph structures

The method of image segmentation by pyramid relinking is extended to the formalism of hierarchies of region adjacency graphs. This approach has a number of advantages: (1) resulting regions are connected; (2) the method is adaptive, and therefore artifacts caused by a regular grid are avoided; and (3) information on regions and boundaries...
