Abstract Crary Ice Rise formed after the Ross Shelf re-grounded ~1 kyr BP. We present new ice-penetrating radar data from two systems operating at center frequencies of 7 and 750 MHz that confirm ice rise is composed a former shelf buried by subsequent accumulation. Stacks englacial diffraction hyperbolas are almost everywhere across central extend up to ~350 m above bed. In many cases, bed ref...

In 3GPP long term evolution (LTE), sounding is used to gain a wideband estimate of the uplink channel. This channel estimate may then be used for several radio resource management related applications such as frequency selective scheduling and beam forming. Code division multiplexing (CDM) enables several users to broadcast sounding reference signals (SRS) simultaneously on the same time and fr...

Introduction: To search for subsurface interfaces and characterize surface roughness, the Shallow Radar (SHARAD) instrument on the Mars Reconnaissance Orbiter is observing past, present, and proposed future Martian landing sites. Orbital and landed imagery and altimetry data show that most sites are located atop layered sequences that extend over tens to hundreds of kilometers and are hundreds ...

Thermal infrared sounding of sulphur dioxide (SO2) from space has gained appreciation as a valuable complement to ultraviolet sounding. There are several strong absorption bands of SO2 in the infrared, and atmospheric sounders, such as AIRS (Atmospheric Infrared Sounder), TES (Tropospheric Emission Spectrometer) and IASI (Infrared Atmospheric Sounding Interferometer) have the ability to globall...

Seafloor topography over seamount areas is crucial for studying plate motions, seafloor seismicity, and ecosystems. However, bathymetry modeling difficult due to the complex hydrodynamic environment, biodiversity, scarcity of shipborne echo sounding data. The use satellite altimeter-derived gravity data a complementary way computation; in particular, incorporation synthetic aperture radar (SAR)...

A quick turnaround Sub-Orbital Student Experiment Module sounding rocket experiment has been designed and built to initiate the Old Dominion University wireless spacecraft bus project for the Mid Atlantic Institute for Space and Technology. The sounding rocket was launched on the 8 of June 2006 from NASA Wallops Flight Facility on Virginia’s Eastern Shore. This wireless sounding rocket experime...

Medication errors are common in hospitals which may occur at prescribing, dispensing and administration level. The objective of this study was to evaluate the dispensing errors that occur mainly due to similar sounding and looking medicines. A cross-sectional and observational study was conducted at Nobel Medical College Pharmacy, Biratnagar, Nepal during the months of August and September 2010...

Mars Express, the first European interplanetary mission, carries the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) to search for ice and water in the Martian subsurface. Developed by an Italian–US team, MARSIS transmits low-frequency, wide-band radio pulses penetrating below the surface and reflected by dielectric discontinuities linked to structural or compositional chang...
