Adaptive Energy-aware Scheduling of Dynamic Event Analytics across Edge and Cloud Resources

The growing deployment of sensors as part of Internet of Things (IoT) is generating thousands of event streams. Complex Event Processing (CEP) queries offer a useful paradigm for rapid decision-making over such data sources. While often centralized in the Cloud, the deployment of capable edge devices on the field motivates the need for cooperative event analytics that span Edge and Cloud computing. Here, we identify a novel problem of query placement on edge and Cloud resources for dynamically arriving and departing analytic dataflows. We define this as an optimization problem to minimize the total makespan for all event analytics, while meeting energy and compute constraints of the resources. We propose 4 adaptive heuristics and 3 rebalancing strategies for such dynamic dataflows, and validate them using detailed simulations for 100 - 1000 edge devices and VMs. The results show that our heuristics offer O(seconds) planning time, give a valid and high quality solution in all cases, and reduce the number of query migrations. Furthermore, rebalance strategies when applied in these heuristics have significantly reduced the makespan by around 20 - 25%.Comment: 11 pages, 7 figure

Beyond the Tunnel Problem, Addressing Cross-Cutting Issues that Impact Vulnerable Youth

Across the country, mayors, commissioners, superintendents, governors, and state policymakers are innovating to address the needs of vulnerable youth. These efforts take many forms: restructuring high schools to improve graduation rates, creating developmentally appropriate interventions to reduce juvenile delinquency, and revamping child welfare practices to keep more youth safely in their homes are just a few of these strategies. Many initiatives, however, are plagued by "crosscutting problems" -- issues that cut across the different agencies that serve youth. Unless crosscutting issues are addressed proactively, they may undermine systemic reforms. This short paper is the first in a series of briefing papers designed to inform officials, practitioners, funders, advocates, scholars and the general public about crosscutting problems and possible solutions to these problems. This paper focuses primarily on the authors' experiences in New York City, though many of the crosscutting problems discussed are known to occur in many jurisdictions large and small. The series starts by presenting a typology of crosscutting issues. The next paper in this series will elaborate on a specific area -- namely, juvenile justice and education. Additional briefing papers will focus on local initiatives that tackle specific problems and more systemic attempts to solve crosscutting issues

Renewed e-learning oriented IHO Cat. B Hydrography Program (2020-) in Belgium

A study onhydrographic education in Belgium carried out a few years ago,pointed out a shortage in hydrographic training. Before the introduction of the new "Postgraduate in Hydrography", most hydrographic surveyors in Belgium work in one of the main Europeandredging companies where they received additional specific hydrographic surveying training.Therefore, in 2013, a 1-year English spoken curriculum degree of "Postgraduate in Hydrography" in Belgium was accredited by the IHO (International Hydrographic Organization). Then, in 2019, a renewed curriculum, including extensive e-learning facilities, was established.The program (Cat-B) is a cooperation between the Geography Department of Ghent University and the Institute for Hydrography of the Antwerp Maritime Academy, which is the hosting institute.The aim is to combine the compulsory theoretical courses with on-the-job training provided by partners in the industry to ensure maximum competences. All courses are lectured in English, and can be taken up over several years to facilitate part-time work. These procedures allow for a qualitative and professional, yet accessible program.The theoretical courses are taught on two different campuses, the campus of the Antwerp Maritime Academy (HZS) and a campus of Ghent University (UGent) based on the available expertise and infrastructure, thus ensuring the quality. As travel time between both cities is relatively fast (ca. 45 min. travel time by public or private transport) together with the boundary condition that both locations are never used on the same day, this presents no problems to the students. The navigation related topics are taught at the Maritime Academy while the geodesy/data management/geology and ICT related topics are provided by the Geography, Geology and Informatics Departments at Ghent University
