MONITORING COARSE SEDIMENT PARTICLE DISPLACEMENT USING A Radio Frequency Identification SYSTEM
2006Co-Authors: Mary Hennessey NicholsAbstract:Coarse particles make up a relatively high contribution to overall sediment yield in ephemeral alluvial channels. A Radio Frequency Identification system was developed and implemented to monitor the displacement of coarse particles following runoff in two upland, ephemeral channels on the USDA-ARS Walnut Gulch Experimental Watershed in southeastern Arizona. Sediment transporting flows are typically of short duration with rapidly rising and falling hydrographs. Commercially available Radio Frequency Identification components including transponders, an antenna, a reader, and software were used to develop a system for locating particles under field conditions. During the 2003 field season 124 particles were located following four runoff events in two ephemeral channels. A total of 340 particle positions were measured with a differential geopositioning system after each particle was located with the Radio Frequency Identification system. The overall recovery rate was 96%. The passive transponder system offers the advantages of low cost, consistent results under harsh environmental conditions, and no need for a power supply in the particle. Buried particles can be located and identified without disturbing channel bed material. The Radio Frequency Identification system can be used to efficiently collect data for developing sediment transport equations and improving mathematical models for simulating sediment transport under natural runoff conditions.

A Radio Frequency Identification system for monitoring coarse sediment particle displacement
Applied Engineering in Agriculture, 2004Co-Authors: Mary Hennessey NicholsAbstract:A Radio Frequency Identification system was implemented to monitor the displacement of coarse particles following runoff in two upland, ephemeral channels on the USDA−ARS Walnut Gulch Experimental Watershed in southeastern Arizona. Commercially available Radio Frequency Identification components including transponders, an antenna, a reader, and software were used to develop a system for locating particles under field conditions. During the 2003 field season, 124 particles were located following four runoff events in two ephemeral channels. The locations of 340 particle positions were measured with a real−time kinematic geopositioning system after each particle was located with the Radio Frequency Identification system. The overall recovery rate was 96%. The passive transponder system offers the advantages of low cost, consistent results under harsh environmental conditions, and no need for a power supply in the particle. The Radio Frequency Identification system can be used to efficiently collect data for developing sediment transport equations and improving mathematical models for simulating sediment transport under natural runoff conditions.

Radio Frequency Identification-enabled capabilities in a healthcare context: An exploratory study.
Health informatics journal, 2015Co-Authors: Robert Hornyak, Mark Lewis, Balaji SankaranarayanAbstract:Increasingly, the adoption and use of Radio Frequency Identification systems in hospital settings is gaining prominence. However, despite the transformative impact that Radio Frequency Identification has in healthcare settings, few studies have examined how and why this change may occur. The purpose of this study is to systematically understand how Radio Frequency Identification can transform work practices in an operational process that directly impacts cost and operational efficiency and indirectly contributes to impacting patient safety and quality of care. We leverage an interdisciplinary framework to explore the contextual characteristics that shape the assimilation of Radio Frequency Identification in healthcare settings. By linking the use of Radio Frequency Identification with specific contextual dimensions in healthcare settings, we provide a data-driven account of how and why Radio Frequency Identification can be useful in inventory management in this setting. In doing so, we also contribute to recent work by information systems scholars who argue for a reconfiguration of conventional assumptions regarding the role of technology in contemporary organizations.

Middleware Technology in Radio Frequency Identification
ZTE communications, 2007Co-Authors: Zhang JianAbstract:Radio Frequency Identification (RFID), as a new technology, has been developing rapidly in recent years. Middleware is one of the most important components in the RFID system. It provides functions of tag data processing and reporting. The mechanism of inner processing is based on state transition of event cycle specification. As a software system, the middleware structure is object-oriented, and it uses the idea of design patterns. The growing trend of middleware may be combining network element management functions, supporting multi-standard of tags, and accommodating different RFID reader vendors.

Radio Frequency Identification rfid
Computers & Security, 2006Co-Authors: C M RobertsAbstract:First conceived in 1948, Radio Frequency Identification (RFID) has taken many years for the technology to mature to the point where it is sufficiently affordable and reliable for widespread use. From Electronic Article Surveillance (EAS) for article (mainly clothing) security to more sophisticated uses, RFID is seen by some as the inevitable replacement for bar codes. With increasing use comes increasing concern on privacy and security. Clearly there is considerable work to be undertaken before RFID becomes as pervasive as bar codes although the tempo of change is increasing rapidly. ing rapidly.

HICSS - Implementation and Usage of Radio Frequency Identification (RFID)
2007 40th Annual Hawaii International Conference on System Sciences (HICSS'07), 2007Co-Authors: Frederick J. Riggins, Bill C. HardgraveAbstract:Whether to solve specific business problems or comply with trading partner mandates, many companies are now engaged in pilot projects using Radio Frequency Identification (RFID). RFID dramatically increases the potential for organizations to collect data about any tagable entity, which has implications for supply chain logistics, customer relationship management, health care systems, human resource management, and privacy/intellectual property policies. However, in many cases the adoption issues and the business case are not well understood for this emerging technology. This mini-track includes three papers on the Implementation and Usage of Radio Frequency Identification (RFID) technology in today?s organization and emphasizes the building of an on-going research tradition in this area.
