iLDM: An Interoperable Graph-Based Local Dynamic Map

Local dynamic map (LDM) is a key component in the future of autonomous and connected vehicles. An LDM serves as a local database with the necessary tools to have a common reference system for both static data (i.e., map information) and dynamic data (vehicles, pedestrians, etc.). The LDM should have a common and well-defined input system in order to be interoperable across multiple data sources such as sensor detections or V2X communications. In this work, we present an interoperable graph-based LDM (iLDM) using Neo4j as our database engine and OpenLABEL as a common data format. An analysis on data insertion and querying time to the iLDM is reported, including a vehicle discovery service function in order to test the capabilities of our work and a comparative analysis with other LDM implementations showing that our proposed iLDM outperformed in several relevant features, furthering its practical utilisation in advanced driver assistance system development.

The open discovery initiative & promoting transparency in discovery

NISO recently updated the Open Discovery Initiative Recommended Practice (https://www.niso.org/publications/rp-19-2020-odi), which outlines best practices for working with library discovery services. It defines ways for libraries to assess the level of content provider participation; streamlines the process by which libraries, content providers and discovery service providers work together; defines models for “fair” linking; and suggests usage statistics that should be collected for libraries and for content providers. The recommendations in this document, created by members of the Open Discovery Initiative Standing Committee, enable libraries, discovery service providers, and content providers to work together to the full extent of their abilities - providing the most effective and rich experience to end users.

Availability of Historical Cadastral Data

A systematic approach to the establishment of the Franciscan Cadastre, which has been performed in most Central European countries, has resulted in the following documents: cadastral maps, cadastral municipality boundary demarcation records, lists of land parcels, lists of building parcels and lists of possessors. The documentation, which is stored in various archives, is digitized and made available to users through catalogs. The availability of documentation was examined in this study using three services in the catalogs—discovery, view and download—of which the largest percentage of documents is available through the discovery service. Documents that are available through the discovery service are described by the metadata standards. In this study, we examined the applicability of geographic information metadata standards and metadata standards to archival documentation in catalogs in which cadastral documentation was found. We determined a lack of application of geoinformation metadata standards, as it was a cadastral dataset, which represented one of the fundamental spatial datasets. The semantic mapping of elements between the applied standards in the catalogs and the geoinformation metadata standard (ISO 19115) showed that it was possible to apply the ISO 19115 standard to documents resulting from the establishment of the cadastre.

Ketorolac in Postoperative Neonates and Infants: A Systematic Review

OBJECTIVE To evaluate the pharmacokinetics and pharmacodynamics, dosing, efficacy, and safety of ketorolac in postoperative patients younger than 6 months of age. METHODS PubMed (1988–July 2020), Medline (1946–July 2020), and EBSCO Discovery Service (1988–July 2020) were searched to identify relevant published articles using the following search terms: ketorolac, neonate, infant. English-language articles evaluating the use of ketorolac in infants younger than 6 months of age were included. RESULTS Eight reports that included 239 infants receiving ketorolac were included. Of the included patients, 237 were younger than 6 months of age. Ketorolac exhibits rapid elimination of the analgesia-producing S (−) isomer, elimination half-life of 0.83 hours. Most patients received 0.5 mg/kg/dose every 6 hours for 48 to 72 hours. Analgesia was demonstrated by reduced use of open-label morphine and significant lowering of Neonatal/Infant Pain Scale scores. Adverse effects were minimal when ketorolac was used in term neonates and infants without baseline renal dysfunction. CONCLUSIONS Randomized placebo-controlled trials of ketorolac use in this population are lacking; however, most published reports noted efficacy and safety with ketorolac in properly selected infants.

Design of P2P-SIP System Network Structure Based on JXTA

Session Initiation Protocol (SIP) is one of the most important signaling connection protocols in the field of VoIP (Voice over Internet Protocol). However, the existing SIP network has some problems such as manual configuration, difficult maintenance and poor scalability. With the development of P2P (Peer-to-Peer) technology, the combination of SIP and P2P has become a trend. JXTA is an open peer-to-peer platform, which provides basic application services for building P2P network. The topic chooses JXTA development platform to build P2P network, and then constructs SIP soft terminal on it. Based on the in-depth study of JXTA structured network and SIP protocol, a P2P SIP system is designed and implemented. The system can maintain normal SIP communication without maintaining the central server. In this paper, the detailed design and implementation process of P2P-SIP system are given, including node join and leave, user join, user search and session establishment. This paper focuses on the implementation process of user search, that is, the collaborative process of discovery service, resolution service, aggregation service and endpoint routing service. Finally, the feasibility of the system is verified by functional test.

Research on the Utilization and Evaluation of Library Resource Discovery Systems in China

According to the investigation of library resources discovery system construction in 20 universities in China, the aggregation discovery service provided by the multi-source aggregation function, the discovery function is based on aggregation and the comprehensive revealing function. This article evaluates user usage and acceptance based on refinements of the functions mentioned above. The investigation shows that compared with the diversity of function, users are more concerned about the practicability, the intuition and the academy. Thus, systems should choose the best sources and pay attention to the metadata normalization, and enhance the correlation to standard datasets.

Making a List and Checking it Thrice: Three Universities Implement Ex Libris’ Leganto

In the 2020-2021 academic year, Clemson University, Coastal Carolina University, and the College of Charleston were the first three institutions in the state of South Carolina to implement Leganto. This implementation followed closely on the heels of a statewide migration involving 55 academic libraries to Ex Libris’ library services platform, Alma, and discovery service, Primo VE. Each institution completed their migration and went live with Alma and Primo VE in June 2020. Coastal Carolina University launched Leganto in July 2020 and Clemson University and College of Charleston each launched Leganto in August 2020. This article explores the faculty engagement, instructional materials, and assessment and usage involved in the launch of Leganto by the three institutions. Common findings are identified, and shared lessons learned are provided.

Web-scale Discovery Service Adoption in Canadian Academic Libraries

This study presents an overview of web-scale discovery service adoption in Canadian academic libraries. Web-scale discovery services (WSDS) have been widely embraced in Canadian academic libraries. EBSCO Discovery Service (EDS) is the most adopted system for colleges and institutes while Primo Central from Ex Libris dominates the university market for web-scale discovery services. Bundling web-scale discovery services with library services platform (LSP) implementations are increasing in Canada. This study shows that Canadian academic libraries that have migrated from a traditional integrated library system (ILS) to an LSP have also opted for their LSP vendor’s corresponding web-scale discovery service. As more Canadian academic libraries implement an LSP bundled with a web-scale discovery service, there may come a time when web-scale discovery services are no longer separated from discussions on LSPs. The choices available for LSP and web-scale discovery services are shrinking due to vendor mergers and acquisitions in this area.

Unified Ontology Implementation of Cloud Computing for Distributed Systems

The ability to provide massive data storage, applications, platforms plus many other services leads to make the number of clouds services providers been increased. Providing different types of services and resources by various providers implies to get a high level of complexity. This complexity leads to face many challenges related to security, reliability, discovery, service selection, and interoperability. In this review, we focus on the use of many technologies and methods for utilizing the semantic web and ontology in cloud computing and distributed system as a solution for these challenges. Cloud computing does not have an own search engine to satisfy the needs of the providers of the cloud service. Using ontology enhances the cloud computing self-motivated via an intelligent framework of SaaS and consolidating the security by providing resources access control. The use RDF and OWL semantic technologies in the modeling of a multi-agent system are very effective in increases coordination the interoperability. One of the most efficient proposed frameworks is building cloud computing marketplace that collects the consumer's requirements of cloud services provider and managing these needs and resources to provide quick and reliable services.
