The majority of research publications in the area of Critical Infrastructure Protection are focused on abstract modelling and simulation efforts. One notable side effect is the large number of proposed models and methodologies contrasted with a comparably small number of publications dedicated to validating or even applying these in the field. Most research papers on the subject limit themselve...

Whether computational algorithms such as latent semantic analysis (LSA) can both extract meaning from language and advance theories of human cognition has become a topic of debate in cognitive science, whereby accounts of symbolic cognition and embodied cognition are often contrasted. Albeit for different reasons, in both accounts the importance of statistical regularities in linguistic surface...

Although species longevity is subject to a diverse range of selective forces, the mortality curves of a wide variety of organisms are rather similar. We argue that aging and its universal characteristics may have evolved by means of a gradual increase in the systemic interdependence between a large collection of biochemical or mechanical components. Modeling the organism as a dependency network...

− Analysis test (parameter analysis) is very important in measurement and test of IC parameters. The key to solve analysis test problems is how to find out optimal characteristic variable group. In this paper, the mathematical model and application method of choosing characteristic variable group are described with the obtained experimental results. It provides the interrelation of IC variables...

This paper uses data from Taiwan’s banking sector to investigate if state-owned banks can serve as an internal regulation mechanism to sustain market competition. In contrast to the traditional second-best literature, the evidence shows that a certain degree of market coordination exis ts in the industry, even if the government owns most of the dominant banks in Taiwan.

The interactions between three or more random variables are often nontrivial, poorly understood, and yet, are paramount for future advances in fields such as network information theory, neuroscience, genetics and many others. In this work, we propose to analyze these interactions as different modes of information sharing. Towards this end, we introduce a novel axiomatic framework for decomposin...

Micropolis is a virtual city that is used for various studies, such as modeling and analyzing water networks. In this paper we model the various interdependencies between three major infrastructures in Micropolis, the power system, the communication network and the water network, in order to study cascades effects between them. Specifically, we develop open hybrid automata models for the main c...

Developing effective protection, mitigation and recovery measures for critical infrastructures is paramount in the wake of increasing natural and human-initiated hazards, risks and threats. Influencing these measures are interconnections (i.e., interdependencies) among infrastructure systems. Understanding the nature of system interdependencies can play an essential role in minimizing and/or re...

The modeling and analysis of critical infrastructures and their interdependencies are essential to discovering hidden vulnerabilities and the related threats to national and international security. Over the past few years, several approaches have been proposed to address this problem. The so-called holistic approaches are relatively abstract, but are easily validated using real economic data. O...
