BLOP BLOP BLOP HOW TO
This perspective paper illustrates some of the challenges for sustained coastal observations and provides details on how to address present gaps. Essential elements of such distributed observation systems are the use of machine-to-machine communication, data fusion and processing applying recent technological developments for the Internet of Things (IoT) toward a common cyberinfrastructure. Ocean observing systems in coastal areas must now move toward an integrated, multidisciplinary and multiscale system of systems, where heterogeneity should be exploited to deliver fit-for-purpose products that answer the diversity and complexity of the requirements from stakeholders and end-users. As a result, there are presently significant differences between countries in terms of sustainability, observing capacity and technologies, as well as methods and research priorities. The Venice lagoon is a difficult scenario for wirelessĬoastal observing systems are typically nationally funded and built around national priorities. The network proved to be reliable and data is openly published on websites for general divul-gation purposes and shared with scientists worldwide. The amount of data coming from sensors on the platform required a broadband connection for real-time analysis, and the 10 Mbps are ad-equate for this purpose. We dealt with this limitation by capping the maximum throughput to 10 Mbps (down to the 100 Mbps that we obtained during the installation tests) to obtain a better fading margin, as well as by leaving a 5.7 GHz link in place as a backup for very rainy days. This solution has very good throughput, although it suffers from more attenuation in case of rain. This led us to move to the 17 GHz band, which is also unlicensed in Europe but less subject to in-terference because of the narrower beam employed and the reduced number of users in this band. Since we are limited to use unlicensed bands, the first point point links were installed at 5.7 GHz, but after some time we began experiencing interference from the many WiFi systems de-ployed in the area.
BLOP BLOP BLOP INSTALL
To reach an offshore platform 15 km off the coast, we had to install dedicated point to point links. The mesh solution provided alternative paths to avoid blockages, but the indirect paths increased the latency and as the data transmission requirements grew more stringent we tried a WiMAX solution with the base station located in a high enough position to minimize block-age. Starting from traditional WiFi links, we moved to mesh networking as a means to deal with the interruptions caused by passing ships that would block the direct radio path.
"Incredibly whimsical and endlessly inventive.In this paper we describe the process that brought us to the deployment of a 17 GHz network in the Venice lagoon to con-nect remote sensors. "Lighthearted, fun and original, this book will delight children and parents alike."- Kirkus Reviews, starred review Simple questions and declarative statements lead young readers along Blop's 110-page journey from the chalkboard to 3-D sculpture and beyond."- Dallas Child Is it a butterfly, star, shamrock? Because it's everything and nothing in particular, Blop takes on a personality of intrepid curiosity - morphing through colors, grown gin size and multiplying, and discovering its own reflection. Instead, award-winning French illustrator Herve Tullet means for you to decide for yourself how to describe the abstract shape inside the funhouse-shaped board book.
"Don't bother looking up "blop" in the dictionary. And as a hat-tip to the book's endless search for innovation, even the format is a novelty - it's a stylish, irregularly-shaped polygon. Since the blops themselves are not characters, it's the sheer volume of variations Tullet dreams up that gives the work its energy. A foil page on a spread mirrors a blop at right ("Blop discovers," written backwards, is legible on the foil.) Blops are decorated like works of art, gnawed on, scribbled on, and even forbidden ("No blopping," reads one page, with a red bar across a blop.) Perforated punch-out blops are included at the end, and a questionnaire ("What do blops eat?") concludes this parade of blop events and transformations. The six-page "Story of Yellow and Blue Blops" ends with a transparent page with a blue blop printed on it placed over a yellow blop, they create green. on every page, one blop (or several, or dozens) do new things, each with a short, hand-lettered title. "Tullet plays with shapes that look like chubby Xs or butterflies - blops," he calls them.
