Compression-performing modems significantly improve the file transfer process over LANs. The use of compression technology can provide even more effective results when applied to WAN. The use of compression-performing bridges or routers can reduce WAN bottlenecks, eliminate or reduce time-out problems caused by time-sensitive legacy mainframe communications protocols, and eliminate or postpone ...

Computational fluid dynamic simulations involve large state data, leading to performance degradation due to data transfer times, while requiring large disk space. To alleviate the situation, an adaptive lossy compression algorithm has been developed, which is based on regions of interest. This algorithm uses prediction-based compression and exploits the temporal coherence between subsequent sim...

Abstract The mediastinum is known as the anatomical structure connecting two pleural sacs. A variety of structures, from organs to veins and arteries, make mediastinal pathology extremely adventurous. We submit case a 67-year-old female patient, former smoker, who presented our clinic with dyspnoea on slight exertion, anterior chest pain ineffective cough. alarming aspect stridor present at reg...

Study Design Retrospective cohort. Objective To clarify the sensitivity of C3-C2 spinolaminar line test as a screening tool for the stenosis of C1 space available for the cord (SAC). Methods Spine clinic records from April 2005 to August 2011 were reviewed. The C1 SAC was measured on lateral radiographs, and the relative positions between a C1 posterior arch and the C3-C2 spinolaminar line were...

Measurement of the intrinsic positive end-expiratory pressure (PEEP(i)) is important in planning the management of ventilated patients. Here, a new recursive least squares method for on-line monitoring of PEEP(i) is proposed for mechanically ventilated patients. The procedure is based on the first-order model of respiratory mechanics applied to experimental measurements obtained from eight vent...

ltrasonography not only permits a detailed assessment of peripheral nerves but also is useful for intrinsic nerve abnormality detection, as in peripheral nerve enlargement (eg, in trauma, peripheral nerve sheath tumors, and nerve compression). Ultrasonography can also be used to locate nerve compression due to an extrinsic factor (eg, compression of the posterior interosseous nerve by the arcad...
