Systems of Systems Perspectives on Critical Infrastructure Management in Response to Climate Change and Sea Level Rise

Yacov Haimes & Eugene Stakhiv
Since 1980, the U.S. has experienced 151 weather disasters with damages exceeding one billion dollars each. With changing climate and development patterns and the severity and frequency of extreme weather events increasing, the United States must address the vulnerability of its complex critical infrastructure, which is largely a fragmented system of systems. The nation’s critical infrastructure provides the essential services that underpin the American way of life. A vast array of interdependent infrastructure and information...

\"But Who Looks East at Sunset?\" Gerard Manley Hopkins and Scientific Perception

Bethany Nowviskie
This essay examines published scientific writings of Gerard Manley Hopkins in the context of his poetry, journal-writing, and correspondence on subjective and objective cognition, or “unusually observant” perception. Hopkins’ response to special atmospheric conditions (the after-effects of the Krakatoa eruption, and the phenomenon of rayons du crepuscule at sunset) is considered in a matrix of Victorian scientific amateurism, conflicting views on observational agency and perspective, and precision in poetic and descriptive language. Key to valid...

Holographic Design of Arbitrary Multi-Beam Leaky-Wave Antennas

Xavier Artiga & Fermín Mira
This paper proposes a versatile method for designing arbitrary multi-beam leaky-wave antennas that can be applied to the synthesis of di erent beams with di erent gains, or of more than two beams. The method is based on superposing multiple objective eld patterns in the context of the holographic design of a modulated impedance surface. In particular, dual-beam
leaky-wave antennas with equal beam gains, and with relative gain di erences of 3dB and 6dB are...

NON-CONVEX CONSENSUS ADMM FOR SATELLITE PRECODER DESIGN

Miguel Ángel Vázquez, Aritra Konar, Luis Blanco, Nicholas D. Sidiropoulos & Ana I. Pérez-Neira
Owing to the rapidly increasing traffic demands on satellite connectivity, the current exclusive frequency allocation is becoming obsolete. Instead, aggressive frequency reuse and interference mitigation techniques are promising ideas that both industry and academia are investigating. This paper proposes an optimization precoding technique for dealing with the multibeam interference due to the aggressive frequency reuse. In contrast to general multiuser multiple input multiple output (MIMO) schemes, multibeam satellite precoding techniques call for frame-by-frame quadratically constrained...

Recherche d'information dans les systémes P2P hétérogènes.

Thomas Cerqueus
RÉSUMÉ. Nous considérons la recherche d'information sémantique dans les systèmes pair-à- pair. Ces derniers semblent être une solution intéressante pour le partage de données car ils garantissent le passage à l'échelle, et gère la dynamicité. Dans ce contexte, il est difficilement imaginable que tous les participants s'accordent sur l'utilisation d'une même représentation sémantique (schéma, ontologie, graphe conceptuel). Dans ce cas, le système est sémantique- ment hétérogène. Cette situation limite l'interopérabilité entre participants. Dans cet article...

Demystifying Cultural Gender Disparities Experienced in Socio-Economic and Political Development in Africa

James Mushori
Gender disproportions have been part and parcel of most African cultures since time immemorial. Demographically, women are over a half population in most of the African countries but their participation in sectors of socio-economic and political spheres have remained inadequately represented. The enduring and biased beliefs on gender roles that view women much less important as compared to men are what forms the basis of concern to the welfare of women and most importantly the...

How to Re-Tool Librarians for Data Curation

Andrew Sallans & Sherry Lake
The University of Virginia Library has begun a process of “re-tooling” subject librarians to meet emerging demands of scientific data management. In leading this new initiative, the Scientific Data Consulting Group (SciDaC) focuses on two main activities: 1) “Data Curation Brown Bag” discussions, and 2) data interviews. Through this process, we hope to gradually help traditional subject librarians develop literacy in issues surrounding scientific data management. Each brown bag session focuses on a very specific...

An Exploratory study of niche market potential of German tree-planting ecotourists to Kenya

David Rempel, Laura Wintersperger, Eva-Maria Schirner & Julia Haase
Climate change is having drastic effects on various areas of the planet, including extreme impacts on weather and rainfall, in various Sub-Saharan East African countries (Hendrix, C. S., & Glaser, S. M. (2007). The willingness (and need) of a niche market to actively improve the damaged ecosystems in small ways is rising. Weaver and Lawton (2007, p 1170) maintain that ecotourism should satisfy three core criteria: “(1) attractions should be predominantly nature-based; (2) visitor interactions...

Universities Third Mission and Business Incubation: Cooperation Between Universities and Business Incubators Demonstrated with the Example “Digital Hub Region Bonn”

Klaus Deimel
Higher Education Institutions (HEIs) should, on the one hand, provide theoretical and practical knowledge to students and, on the other hand, make valuable contributions to theoretical knowledge and provide new insights by means of research. However, HEIs have to face changing and increasing demands with respect to what they are expected to achieve. Education and research issues are no longer enough, what matters today is the so called “third mission”. A specific example for implementing...

Culture and value trade-offs for successful entrepreneurship in Africa

J. Otto Kroesen & David J. Ndegwah
In Africa slowly but steadily a transformation is taking place in the management styles of enterprises. There is a trend towards more precise time management, more precision in dealing with increasingly sophisticated technology, more feedback from the bottom to the top in order to manage the processes properly, more professionalism and independence of the individual worker. This contribution makes two points: first, neither cultures nor the so-called mental states of individuals are ever static, but...

Faster Secure Two-Party Computation Using Garbled Circuits

Yan Huang, David Evans, Jonathan Katz & Lior Malka
Secure two-party computation enables two parties to evaluate a function cooperatively without revealing to either party anything beyond the function's output. The garbled-circuit technique, a generic approach to secure two-party computation for semi-honest participants, was developed by Yao in the 1980s, but has been viewed as being of limited practical significance due to its inefficiency. We demonstrate several techniques for improving the running time and memory requirements of the garbled-circuit technique, resulting in an implementation...
