Research on the Upgrading Path of Emerging Industry Innovation Service Network

Innovation service network is the inevitable result of the collaborative cooperation of innovation service subjects, and also an important strategic resource for innovation activities in emerging industries. The research of innovation service network has important decision reference value for the promotion of collaborative service capability for the innovation demand of emerging industries. By analyzing the evolution process and law of innovation service network in emerging industries, improving the main line around the ability of collaborative service, combining the evolution stage of innovation service network, the complexity of innovation demand and the integration of service resources, this paper focuses on designing the upgrade path of innovation service network based on key nodes, the path of innovation service network upgrade based on service chain integration, and the upgrade path of innovation service network based on core network coordination, in order to optimize the structure of innovation service network of emerging industries and improve its ability of collaborative service provides theoretical guidance, which is of great practical significance to support the innovation and development of emerging industries.

How will new orbital motorways reshape accessibility in Bratislava metropolitan area?

Dynamic economic expansion of metropolitan regions in post-communist central Europe induces dynamic traffic growth, which calls for new transport network solutions and improvements to existing transport infrastructure within the regions. This is also the case of Bratislava as the capital city of post-communist Slovakia, which has recently been facing new economic and urban development challenges. A booming labour market, intensive suburbanisation processes, traffic expansion and urban (re-)development bring new conflicts and demand for grand-scale transport projects. An ongoing upgrade of the motorway system in the region of Bratislava will result in the construction of a substantial part of an orbital motorway surrounding the southern and eastern parts of the city. The potential effects of the motorway network-upgrade projects on the city urbanism are probably immense. This paper attempts to evaluate the possible changes in accessibility within the road network after completion of motorway upgrading project D4/R7 in the metropolitan area of Bratislava. The interaction potential of both population and jobs was applied here to assess possible impacts of road network enhancement on accessibility of places of residence and of work.

The future strong motion national seismic networks in Central America designed for earthquake early warning.

<p>The national seismic networks in Central America have been developing network-based early warning since 2016 for Nicaragua, 2018 for El Salvador and 2019 for Costa Rica. This effort is part of a project with the Swiss Seismological Service (ETH Zurich) including funds for accelerograph deployment. At each network, delay for first earthquake parameter estimations have been significantly reduced by optimizing data acquisition, metadata quality, and configuration of the EEW algorithms implemented in SeisComP3, i.e. Virtual Seismologist and the Finite fault rupture Detector. Issues remain with significant numbers of deployed instrumentation that for a variety of reasons, do not optimally contribute to the EEW systems. Building on our experience so far, we design national network upgrades that will optimize the earthquake early warning performance in the Central America region, mitigating the current issues with velocimeter clipping during large events, datalogger delays, and incomplete network coverage. The new instruments have been selected after testing all available EEW-capable accelerographs natively compatible with SeisComP3 including class A force balance accelerometers as well as MEMs. To justify our instrument selection, we summarize the performance of these different instruments. We model and discuss reference maps for performance expectations, and present planned instrument vaults. Our primary focus is on minimizing first alert times but we also wish to accentuate the broad value of the network upgrade for seismological monitoring showing changes in the magnitude of completeness in the region. We demonstrate the value of the network upgrade for earthquake early warning with real-time processing simulation using synthetic data for the maximum magnitude earthquake expected for the Central America subduction zone.</p>

The Canadian National Seismograph Network: Upgrade and Status

The Canadian National Seismograph Network (CNSN) operated by Natural Resources Canada consists of approximately 200 stations. Data from this network are used to produce the national earthquake catalog, to provide alerts in the aftermath of an earthquake, to develop the national seismic hazard maps, and for research within Canada and internationally. A significant upgrade to the instrumentation and infrastructure of the CNSN, which began in 2014, is nearing completion. The newly refurbished network is uniform in terms of instrumentation with the remaining single-component short-period stations converted to three-component broadband stations and consistent sampling rates across the network. Strong-motion instruments are now collocated with weak-motion instruments at many sites in all regions of Canada, and there is also a significant increase in the number of stand-alone strong-motion sites. Improvements in telecommunications were aimed at improving reliability and decreasing latency. All upgraded stations undergo a series of quality checks before the data are approved for dissemination. Data from the CNSN are freely available to the seismological community and the general public.
