This paper presents a method for measuring signal backscattering from an RFID tag and calculating tag radar cross-section (RCS), which depends on the chip input impedance. We present a derivation of a theoretical formula for RFID tag radar cross-section and an experimental RCS measurement method using a network analyzer connected to an antenna in an anechoic chamber where the tag is also locate...

* This paper is a condensation of 4-D/RCS: A Reference Model Architecture for Demo III, NISTIR 5994, March 1997 ABSTRACT 4-D/RCS is a reference model architecture that integrates the NIST (National Institute of Standards and Technology) RCS Real-time Control System [Albus & Meystel],with the German (Universitat der Bundeswehr Munchen) VaMoRs 4D approach to dynamic machine vision [Dickmanns]. 4-...

BACKGROUND Rural medical workforce shortage contributes to health disadvantage experienced by rural communities worldwide. This study aimed to determine the regional results of an Australian Government sponsored national program to enhance the Australian rural medical workforce by recruiting rural background students and establishing rural clinical schools (RCS). In particular, we wished to det...

Currently there is no control for real-time traffic sources in IP networks. This is a serious problem because real-time traffic can not only congest the network but can also cause unfairness and starvation of TCP traffic. In this paper, a new rate control scheme, RCS, is introduced for real-time traffic in networks with high bandwidth-delay products and high bit error rates. RCS is based on the...

Spaceborne synthetic aperture radars (SARs) measure surface radar cross section (RCS) with ground resolutions from 25 to 100 m. In turn, the RCS of the ocean surface is a function of wind speed and direction. Over the past few years, we have been routinely using RCS measured by the RADARSAT SAR to compute highresolution wind speed. We have converted over 3000 wide-swath SAR RCS images, provided...

OBJECTIVES The task of grinding sandstone with a 5-inch angle grinder is a major source of exposure to respirable crystalline silica (RCS), known to cause diseases such as silicosis and lung cancer among workers who work with these materials. A shroud may be a suitable engineering control for this task. The objectives of this study were to evaluate the effectiveness of four commercially availab...

PURPOSE Subretinal electrical stimulation (SES) from microphotodiode arrays protects photoreceptors in the RCS rat model of retinitis pigmentosa. The authors examined whether mer(kd) mice, which share a Mertk mutation with RCS rats, showed similar neuroprotective effects from SES. METHODS Mer(kd) mice were implanted with a microphotodiode array at postnatal day (P) 14. Weekly electroretinogra...

In protein, conformational changes are often crucial for function but not easy to observe. Two functionally relevant conformational intermediate states of photosynthetic reaction center protein (RCs) are trapped and characterized at low temperature. RCs frozen in the dark do not allow electron transfer from the reduced primary quinone, Q(A)(-), to the secondary quinone, Q(B). In contrast, RCs f...

Despite its prominent placement between the retina and primary visual cortex in the early visual pathway, the role of the dorsal lateral geniculate nucleus (dLGN) in molding and regulating the visual signals entering the brain is still poorly understood. A striking feature of the dLGN circuit is that relay cells (RCs) and interneurons (INs) form so-called triadic synapses, where an IN dendritic...

Normal retinal pigment epithelial (RPE) cells were transplanted into retinas of Royal College of Surgeons (RCS) dystrophic rats at different stages of the retinal disease process. RPE-cell transplantation at 10, 17 and 26 days resulted in rescue of photoreceptor cells, such that at 4 months the outer nuclear layer (ONL) was 8-10 cells in thickness as shown in retinas of age-matched control rats...
