Image compression is the reduction or elimination of redundancy in image data representation in order to achieve savings in storage and communication. In this paper we propose a method for image compression and decompression using nested IFFT and FFT which works on both color and grey images. This technique is simple in implementation and utilizes less memory and also requires less computationa...

CONTEXT In recent decades, the fastest growth in lumbar surgery occurred in older patients with spinal stenosis. Trials indicate that for selected patients, decompressive surgery offers an advantage over nonoperative treatment, but surgeons often recommend more invasive fusion procedures. Comorbidity is common in older patients, so benefits and risks must be carefully weighed in the choice of s...

OBJECTIVE Cubital tunnel syndrome is the second most common entrapment neuropathy of the upper extremity. Although many different operative techniques have been introduced, none of them have been proven superior to others. Simple cubital tunnel decompression has numerous advantages, including simplicity and safety. We present our experience of treating cubital tunnel syndrome with simple decomp...

With the widening gap between processor and memory speeds, memory system designers may find cache compression beneficial to increase cache capacity and reduce off-chip bandwidth. Most hardware compression algorithms fall into the dictionary-based category, which depend on building a dictionary and using its entries to encode repeated data values. Such algorithms are effective in compressing lar...
