Constellation Coil
Introduction: A multi-port array coil provides individual RF field profiles that, under the static control of B1 shimming coefficients or dynamic control of parallel RF pulses, are weighted and superimposed to create the RF field. The coil therefore plays a central role in the induction of a temporally/spatially varying B1 field for creating an excitation profile, and meanwhile, a concomitant E...
متن کاملConstellation Detection
In the night with clear sky, the beautiful star patterns attract lots of star gazers and photographers. Constellation is a convention that people used to partition the stars with myth and stories behind each constellation, making the starry sky more compelling. However, the constellation detection requires complicated knowledge and experience. Our team’s goal is to automatically detect the cons...
متن کاملTowards Optimality in Constellation
Communication Theory Mini Conference Globecom 97 Towards Optimality in Constellation Labeling Richard D. Wesel, Christos Komninakis, and Xueting Liu University of California, Los Angeles, CA 90095-1594 Abstract Robust trellis codes that perform well on channels with severe, correlated fading require low rates and do not employ uncoded (pass-through) bits. For this trellis code design problem, n...
متن کاملRanging the GNSS Constellation
Laser ranging is an indispensable independent tool for validating the precise orbits determined for GNSS satellites using microwave pseudorange observations since decades. SLR allowed it to identify orbit modeling issues. Including albedo radiation pressure and antenna thrust, among others, into the GPS orbit model allowed it to basically eliminate the observed SLR bias. For the first Galileo s...
متن کاملSaVi: satellite constellation visualization
SaVi, a program for visualizing satellite orbits, movement, and coverage, is maintained at the University of Surrey. This tool has been used for research in academic papers, and by industry companies designing and intending to deploy satellite constellations. It has also proven useful for demonstrating aspects of satellite constellations and their geometry, coverage and movement for educational...
