Huge amounts of geospatial rasters, such as remotely sensed imagery and environmental modeling output, are being generated with increasingly finer spatial, temporal, spectral and thematic resolutions. Given that CPUs on modern computer systems are three orders of magnitude faster than disk I/O speed and two orders of magnitude faster than network bandwidth, it becomes more and more beneficial t...

Technological developments for several years have resulted in the handling (storing, exchanging or processing) of increasingly important data various fields and particularly medical field. In this works we present a new image compression / decompression algorithm based on quaternion wavelet transform (QWT). This is simple, fast efficient. It has been applied to images. The results obtained afte...

BACKGROUND This study was designed to compare the efficacy of the transpalpebral versus endoscopic approach to decompression of the supraorbital and supratrochlear nerves in patients with frontal migraine headaches. METHODS The medical charts of 253 patients who underwent surgery for frontal migraine headaches were reviewed. These patients underwent either transpalpebral nerve decompression (...

Trace-driven simulation is a simple, fast, and convenient approach to simulate computer architecture for power consumption, throughput, CPU time, and other factors. However, trace-driven simulation requires a massive storage space to save the trace files of benchmark programs. Therefore, an important task is how to design a compression method that reduces the storage space of trace files effici...

BACKGROUND Suprasellar meningiomas often invade the optic canals (OCs). The feasibility of removing these tumors through a minimal-access endonasal route has been demonstrated, but the importance, safety, and timing of OC exploration and decompression are not well described. OBJECTIVE To create a simple decision-tree algorithm for OC exploration and decompression in the endonasal endoscopic s...

objectives: to compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. methods: the test was prospective and randomized control trial. the structure of trial was urban physical medicine and rehabilitation clinic. participants was included of a total of 124 subjects with chronic low back pain (lbp) and evidence of a degenerative and/or herniate...

we evaluated the specific pattern of pre- and postoperative neurological signs and symptoms of cervical spondylotic myelopathy (csm) to determine [mdings which had a predictive value for surgical outcome. consecutive patients with csm caused by osteophytic ridge or intervertebral disc herniation who underwent anterior cervical decompression and fusion in loghman hakim hospital from 1999-2003 we...

traumatic retrolisthesis is a rare injury and may result in intervertebral disc extrusion and nerve root injury. these injuries are highly unstable and require surgery for decompression and stabilization. traumatic retrolisthesis of l5 with acute l5/s1 disc extrusion associated with nerve root injury has not been reported previously in english literatures. we herein report a case of traumatic r...

reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. almost all cases of trigeminal neuralgia (tng) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (hfs) (nine out of 10 c...
