ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / Space Link Extension (SLE) is a set of recommended standards for mission cross support developed by the Consultative Committee for Space Data Systems (CCSDS). The SLE recommendations define protocols for extending the space link from ground terminals to other facilities deeper within a ground network, allowing distributed access to space link telecommand and telemetry services. The SLE protocols are widely used to provide cross support between sites, programs, and agencies. In traditional SLE deployments, individual service instances have been manually provisioned well in advance of the commencement of cross support for a particular mission, and hardware and software resources have been allocated to those service instances at the time of provisioning. While valid, this approach requires that dedicated resources be provided for each mission and service instance, and limits an SLE provider's ability to reallocate resources in real time based on system availability or other factors. This paper discusses an alternative approach to SLE service provisioning, in which individual service instances are assigned resources from a common resource pool at the time that each service instance is initialized. The paper addresses the key design elements and technical tradeoffs involved in this approach, and discusses the potential benefits with regard to load balancing, equipment reuse, and resiliency against system failure.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Consultative Committee for Space Data Systems (CCSDS) is an international organization of national space agencies that is branching out to provide new standards to enhanced reuse of spacecraft equipment and software. These Spacecraft Onboard Interface (SOIF) standards will be directed towards a spacecraft architecture, as a distributed system of processors and busses. This paper will review the services that are being proposed for SOIF. These services include a Command and Data Acquisition Service, a Time Distribution Service, a Message Transfer Service, a File Transfer Service, and a CCSDS Packet Service. An Instrument & Subsystem “Plug & Play Service is currently under study, but is included in this paper for completeness.

The Master thesis focuses on the application of Information Systems in the field of Library and Information Science.  Within the context of organizational learning, a collaborative user-centered approach is used to produce desired system characteristics and future research suggestions. More specifically, this research study explores the library users’ and academic librarians’ perceptions of the current library discovery and access services as mediated through the Online Public Access Catalogue (OPAC) of the Academic Library of the School of Philosophy at Athens University in Greece. Additionally, it explores their desired characteristics for the ‘public facing’ Integrated Library System (ILS), of which the OPAC constitutes a module, in order to generate recommendations that guide the Academic Library staff members’ collaborative design of a more user-centered library information system. The study is built upon the systems thinking framework of Checkland’s Soft Systems Methodology (SSM). Applied theories and design processes guide research processes aimed at advancing both inclusive social learning and system improvements.

Indiana University-Purdue University Indianapolis (IUPUI) / Identifying spatial and temporal patterns of disease occurrence by mapping the residential locations of affected people can provide information that informs response by public health practitioners and improves understanding in epidemiological research. A common method of locating patients at the individual level is geocoding residential addresses stored in electronic medical records (EMRs) using address matching procedures in a geographic information system (GIS). While the process of geocoding is becoming more common in public health studies, few researchers take the time to examine the effects of using different address databases on match rate and positional accuracy of the geocoded results. This research examined and compared accuracy and match rate resulting from four commonly-used geocoding databases applied to sample of 59,341 subjects residing in and around Marion County/ Indianapolis, IN. The results are intended to inform researchers on the benefits and downsides to their selection of a database to geocode patient addresses in EMRs.
