On energy harvesting from a vibro-impact oscillator with dielectric membranes
No full textA vibro-impact mechanical system comprising of a ball moving freely between two dielectric membranes located at a certain distance from each other is studied. The system generates electricity when the ball moving due ambient vibrations impacts one of the membranes. The energy harvesting principle of the proposed system is explained and then used to formulate a numerical model for estimating the system output voltage. The dynamic behavior and output performance of the system are thoroughly studied under a harmonic excitation, as well as different initial conditions and various values of the restitution coefficient of the membranes. The delivered research results are useful for selecting the system parameters to achieve its optimal output performance in a realistic vibrational environment. Potential application of the proposed system for energy harvesting from car engine vibrations is presented

Le « val » comme laboratoire de géographie humaine ? Les avatars du Val d'Anniviers
No full textAbstract: The "val" as a laboratory of human geography? The saga of Val d'Anniviers. The author analyses the methodological project initiated by Jean Brunhes in his study of an alpine valley considered as a «small isolated world», ideally suited to a quasi-experiment. The author looks at the variations in the text, from its first publication as an article to its inclusion in a human geography manual dating back to 1910 and republished in the middle of the 1950s, and the epistemological meaning of these differences. Finally the author attempts to interpret the rereading of this classic monograph from the viewpoint of the development of a discipline and the issue of social change.Résumé : L'article analyse le projet méthodologique initialement poursuivi par Jean Brunhes dans son étude d'une vallée valai- sanne considérée comme un petit monde isolé susceptible d'une quasi-expérimentation. Il étudie les variations du texte, de sa publication en article à son insertion dans un manuel de géographie humaine réédité de 1910 au milieu des années cinquante, et leur signification épistémologique. Enfin, il tente d'interpréter les relectures de cette monographie classique, au regard de l'évolution d'une discipline et de la problématique du changement social.Robic Marie-Claire.

The Splendid Summer: Autonomous Underwater Vehicle Operations at The Center for Coastal and Ocean Mapping
No full text**In collaboration with the Coastal Sediments, Hydrodynamics and Engineering Lab University of Delaware**
The UNH Center for Coastal and Ocean Mapping operates, in collaboration with the University of Delaware, a “Gavia” model AUV, manufactured by Hafmynd EHF of Reykjavik, Iceland. The Gavia will be introduced, detailing it’s many sensor suites and capabilities. Adventures from a summer of training, learning and numerous expeditions will be recounted, including missions to our own Mendum’s Pond, Delaware Bay, Chesapeake Bay, Lake Tahoe and Abaco, Bahamas. Along the way many engineering and scientific challenges have been unearthed which will be discussed in detail as well as ongoing developments of new sensor modules and up coming missions.
Presenter Bio
Val Schmidt is pursuing a Ph.D. in Ocean Engineering under professors Chris d\u27Moustier and Larry Mayer.
Before coming to CCOM, Val served in the US Submarine Service aboard the USS HAWKBILL (SSN-666). In this capacity, Val participated in two dedicated science ( SCICEX ) missions to the Arctic in 1998 and 1999. He has since worked for Qwest Communications developing applications for Voice Over IP technologies and more recently as a research engineer for the Lamont-Doherty Earth Observatory where he built instrumentation, installed navigation and communications systems, and designed data systems for oceanographic research ships.
Val is the lead author of the MB-System Cookbook. The Cookbook provides documentation for the open source swath mapping data processing suite. He also co-developed SWAP - the Ship-to-Ship Wireless Access Protocol - a wireless mesh-networking system for the UNOLS oceanographic research fleet.
Val has a terrific and beautiful wife, Alice and a mean cat, Kokua
Towards a European Cal/Val service for earth observation
No full textSocietal dependence on, and commercial and scientific exploitation of Earth-Oriented remote sensing from satellites is growing at an exponential rate. The comprehensive EU Copernicus programme provides a major contribution to the global effort, but even so, to achieve the necessary global and temporal coverage requires synergistic cooperation and associated interoperability of the Worlds sensors. For a user to exploit Earth Observation (EO) data there must exist confidence in data characteristics, quality and reliable delivery. Although long-term data records for climate may be the most demanding in nature, generation of analysis-ready operational data sets for applications, as diverse as food security to pollution monitoring, all require the user to have some quantitative level of confidence in the data and derived information. A long-term Calibration/Validation (Cal/Val) vision necessitates clear ownership and long-term funding. Delineating the roles of the European Commission (EC), space agencies and member states in long-term Cal/Val would provide clarity. It is clear that the space agencies have the responsibility to meet the mission requirement of their spaceborne instruments but long-term validation is often entrusted to interested parties bringing their own resources to the task. Furthermore, there is a critical need for Fiducial Reference Measurements (FRMs), acquired in operational mode, and comprehensive in coverage both spatially and temporally, to assure that the satellite product accuracies are met. This paper discusses the current status, gaps and challenges regarding long-term Cal/Val of EO satellites and recommends the creation of a European coordinating entity for satellite product calibration and validation. The proposed entity would be an integrative organization coordinating the European Cal/Val activities in partnership with the member states and the space agencies and working together with existing data providers to secure access to satellite and in-situ data of traceable FRM standards.Atmospheric Remote Sensin

Utopia as Escapism, Escapism as Protest: Exploring the radical art and architecture of 1968 - 1989 Czechoslovakia, the case for VAL collective
No full textRadical experimentation, formal plurality, and oscillation between architecture and visual arts permeated the 50s and 60s generation of architects and artists on both sides of the politically divided Europe. Central and Eastern European examples from this period are often undervalued, if addressed at all, both by Western European standards and even their local contexts. VAL—Voies et Aspects du Lendemain—collective was formed in 1968 Czechoslovakia by the conceptual artist Alex Mlynárčik and the architects Viera Mecková and Ľudovít Kupkovič. VAL developed eight distinct utopias and megastructures in parallel to the global trends and Michel Ragon’s techno-centric theory of prospective architecture. As the height of VAL’s activity coincides with the peak of the normalisation period in the 70s Czechoslovakia, their utopian projects remain resistant to clear-cut interpretation then and now. Heliopolis, Akusticon, and the People’s Assembly of Argillia are three distinct projects of VAL explored in reference to the themes of monumentality and architecture-sculpture, prospective architecture, and performance art influenced by Nouveau Réalisme. Despite the unobstructed idealism that VAL emanates, it is argued that VAL’s proposals go beyond an uncritical techno-positive utopia and can hardly be distilled from the irony and socio-cultural critique. And it is in the act of designing the libertarian utopias that VAL members found a form of individual escapism as means to express themselves creatively and to manageably live in a totalitarian regime—utopia as escapism. By subverting the expectations of what are the forms of expressing architectural dissent, escapism is understood as an act of resistance. Resistance to socio-cultural regression, economic depression, professional frustrations, and personal disillusionment with the failed Communist utopia—escapism as protest. The thesis questions our contemporary standing towards Central and Eastern European architects and artists whose work—as illustrated by VAL—entails complexities and contradictions of its socio-cultural and political context.AR2A011Architecture, Urbanism and Building Science
