Eecient Optimal Recompression
نویسنده
چکیده
An eecient variant of an optimal algorithm is presented, which reorganizes data that has been compressed by some on-they compression method, into a more compact form, without changing the decoding procedure. The algorithm accelerates and improves the space requirements of a known technique based on a reduction to a graph-theoretic problem, by reducing the size of the graph, without aaecting the eeciency of the solution that is optimal for the given encoding method. The new method can eeectively improve any static dictionary compression scheme using a static encoding method, and in particular some LZ77 variants.

Bone cement distribution in the vertebral body affects chances of recompression after percutaneous vertebroplasty treatment in elderly patients with osteoporotic vertebral compression fractures
OBJECTIVE Percutaneous vertebroplasty (PVP) is a surgical procedure that has been widely used to treat patients suffering from osteoporotic vertebral compression fractures (OVCFs). The procedure involves injection of bone cement into a fractured vertebra. In this study, we investigated whether the distribution of the cement in the vertebral body is related to the occurrence of recompression aft...
متن کاملEffect of severity, time to recompression with oxygen, and re-treatment on outcome in forty-nine cases of spinal cord decompression sickness.
For systematic study of the effects of clinical severity, time to recompression with oxygen, and re-treatment on outcome from spinal cord DCS, case records from the recompression chamber at the U.S. Naval Station Subic Bay were reviewed. Forty-nine cases of spinal cord DCS were classified using a numerical severity index and time to recompression with oxygen. Cases were divided by initial sever...
متن کاملGuiding principles in choosing a therapeutic table for DCI hyperbaric therapy.
Hyperbaric therapy is the basis of treatment for pervasive development disorders. For this reason, the choice of the right therapeutic table for each case is critical. Above all, the delay in recompression time with respect to the first symptoms and to the severity of the case must be considered. In our experience, the use of low-pressure oxygen tables resolves almost all cases if recompression...
متن کاملThermal Efficiency Improvement of the Pilot Plant Distillation Column by Vapor Recompression
The simulation and steady state operation of a vapor recompression pilot plant distillation column is studied in order to improve the thermal efficiency. A binary system of ethanol-water mixture is used. The simulation is carried through ASPEN PLUS version 9.3-1. Energy reduction of 89.26% is obtained comparing to the conventional distillation and the thermodynamic efficiency is improved from 1...
متن کاملRecompression treatment for decompression illness: 5-year report (2003-2007) from National Centre for Hyperbaric Medicine in Poland.
A serious diving accident can occur in recreational diving even in countries where diving is not very popular due to the fact that diving conditions there are not as great as in some tropical diving locations. The estimated number of injured divers who need recompression treatment in European hyperbaric facilities varies between 10 and 100 per year depending on the number of divers in the popul...
