Real-time optically processed face-recognition system based on arbitrary moire contours
(1996-07-12)A real-time diffraction based optical processed 3-D shape recognition system has been built and demonstrated. The system uses an Ar-ion laser interferometer to project variable spatial frequency structural illumination on ... -
Real-time performance analysis of wireless multimedia networks based on partially observed, multivariate point processes
(2000-07-26)Third-generation (3G) wireless networks will support integrated multimedia services based on a cellular extension of a packet-switched architecture using variants of the Internet protocol (IP). Services can be categorized ... -
Real-Time Regularized Ultrasound Elastography
(2009)This paper introduces two real-time elastography techniques based on analytic minimization (AM) of regularized cost functions. The first method (1D AM) produces axial strain and integer lateral displacement, while the ... -
A Real-Time Solution Strategy for Estimation of Aerothermal Heating for Reentry Vehicles
(2017-12)Direct measurement of flight environment on a heat shield of a Reusable Launch Vehicle (RLV) is critical due to the extremely aerothermal heating experiences during the reentry phase. An alternative approach is to install ... -
RECENT OCCURRENCE OF THE SMALLTOOTH SAWFISH, PRISTIS PECTINATA (ELASMOBRANCHIOMORPHI: PRISTIDAE), IN FLORIDA BAY AND THE FLORIDA KEYS, WITH COMMENTS ON SAWFISH ECOLOGY
(2004)Encounters with the smalltooth sawfish, Pristis pectinata, in Florida Bay and the Florida Keys were documented by soliciting information from anyone who might have encountered them in these areas. Each person who had ... -
Recoiling supermassive black holes: A search in the nearby universe
(2014-11-23)The coalescence of a binary black hole can be accompanied by a large gravitational recoil due to anisotropic emission of gravitational waves. A recoiling supermassive black hole (SBH) can subsequently undergo long-lived ... -
A Recommender System for Improving Program Security Through Source Code Mining and Knowledge Extraction
(2018-07)The security of computer programs and systems is a very critical issue. Threats against computer networks and software are on the rise. Therefore, businesses and IT professionals should take steps to ... -
Reconstructing the stellar mass distributions of galaxies using S 4G IRAC 3.6 and 4.5 μm images. II. the conversion from light to mass
(2014-06-03)We present a new approach for estimating the 3.6 μm stellar mass-to- light (M/L) ratio Υ3.6 in terms of the [3.6]-[4.5] colors of old stellar populations. Our approach avoids several of the largest sources of uncertainty ... -

A redescription of Echinaster Modestus Perrier, 1881 (Asteroidea: Spinulosida) from the eastern Gulf of Mexico and the West Indies
(1981-05)The seastar Echinaster modestus Perrier, 1881, is redescribed and a lectotype is designated. Echinaster spp. from the west coast of Florida used in recent experimental studies are not E. modestus. -
Redirected Free Exploration with Distractors
(2009)Users in virtual environments often find navigation n1ore difficult than in the real world, Our new locomotion interface, Redirected Free Exploration with Distractors (RFED), enables users to walk in larger-than-tracked ... -
Redox-mediated quorum sensing in plants
(2017-09-13)The rhizosphere, the narrow zone of soil around plant roots, is a complex network of interactions between plants, bacteria, and a variety of other organisms. The absolute dependence on host-derived signals, or xenognosins, ... -
Reduced index sparse representation in a parallel environment
(2004-07-19)Sparse-matrix/dense-vector multiplication algorithms are not as highly developed as algorithms for dense matrices. Dense matrix multiplication algorithms have been made efficient by exploiting data locality, parallelism, ... -
Reduced Sample Minimum Strength Estimates for Novel Material Systems: Effects on Confidence and Structural Risk
(2021-07)There are ongoing efforts to standardize the materials, methods and process controls used in additive manufacturing. To support the broader use of additive manufacturing (AM) in the aerospace industry, the statistics working ... -
Reduction of multiplicative noise using higher-order statistics
(2003-09-12)We used a higher-order correlation-based method for signal denoising of images corrupted by multiplicative noise. Using the logarithm of an image, we applied a third-order correlation technique for identification of wavelet ... -
Reef-Building Threatened by Ecosystem Decline: A Case Study from Buck Island, U.S. Virgin Islands
(2017-05)Coral reefs are critical barriers to coastal erosion and flooding throughout tropical regions, but their role in coastal protection is threatened by declining coral populations and sea-level rise. Climate change is causing ... -
Reference point indentation is not indicative of whole mouse bone measures of stress intensity fracture toughness
(2014-10-14)Bone fragility is a concern for aged and diseased bone. Measuring bone toughness and understanding fracture properties of the bone are critical for predicting fracture risk associated with age and disease and for preclinical ... -
Refinements of the Concept of Privacy in Distributed Computing
(2020-12)In light of the tremendous development of technology in the modern world in which we live, privacy concerns are increasing, especially after the massive spread of distributed computing systems and the technologies that ...
