We present work-optimal PRAM algorithms for Burrows-Wheeler compression and decompression of strings over a constant alphabet. For a string of length n, the depth of the compression algorithm is O(log n), and the depth of the the corresponding decompression algorithm is O(log n). These appear to be the first polylogarithmic-time work-optimal parallel algorithms for any standard lossless compres...

Investigating the transient behaviour of liquid CO2 decompression is great importance to ensure safety pipeline transportation in carbon capture and storage (CCS) technology. A computational fluid dynamics (CFD) model based on non-equilibrium phase transition Span–Wagner equation state (EoS) was developed study effects actual flowing within decompression. Then, CFD verified by comparing simulat...

Tension pneumothorax can occur as a potentially life threatening complication of chest trauma. is commonly treated with needle decompression, both the 2nd intercostal space in midclavicular line and 4th/5th anterior axillary. A 45 years old man came to our emergency department after blunt injury presenting tension unstable hemodynamic decompression using 14 gauge (4.5 cm) cannula at mid clavicu...

There is dispute as to whether paradoxical gas embolism is an important aetiological factor in neurological decompression illness, particularly when the spinal cord is affected. We performed a blind case-controlled study to determine the relationship between manifestations of neurological decompression illness and causes in 100 consecutive divers with neurological decompression illness and 123 ...
