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...

We have reviewed 54 hips in 46 patients from 2 to 14 years after a joint-preserving operation for idiopathic avascular necrosis of the femoral head. The choice between core decompression (17 hips), bone grafting (18), rotation osteotomy (15) or varus osteotomy (4) was determined by the stage and location of the area of necrosis. The overall success rate was unexpectedly low at 60%. Core decompr...

This paper describes a new compression/decompression methodology for using an embedded processor to test the other components of a system-on-a-chip (SoC). The deterministic test vectors for each core are compressed using matrix-based operations that significantly reduce the amount of test data that needs to be stored on the tester. The compressed data is transferred from the tester to the proce...

ABSTRACT A 47-year-old gentleman, with underlying seborrhoeic dermatitis that was treated with steroid therapy, and hepatitis B, presented with pain in his right hip. He was diagnosed with stage 2 osteonecrosis of the right hip (Ficat and Arlet classification). Core decompression and bone grafting was performed but recovery was complicated by a surgical site infection. Wound debridement, remova...

stage osteonecrosis of the femoral head (ONFH), the factors normally considered are the progression of the disease and the patient’s age. Although most clinicians agree that the focus, when first treating patients under 50 years of age, should be on preserving the joint, there is significant controversy as to the appropriate procedure in any given case. Core decompression is one of the joint sa...
