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...

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...

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...

Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...

A new approach to spatialisation, based on the idea of projecting sounds through virtual sounding objects, is proposed, and initial experiments are carried out using a modal synthesis model of a rectangular membrane. The effects of varying the dimensions and damping parameters of the model on the perception of spatial attributes are discussed, as well as the relevance to sound diffusion.
