The wavelet transform has itself a useful tool in the field of 1-dimensional and 2-dimensional signal compression systems. Due to the growing importance of this technique, there is an increasing need in many working groups for having a development environment which could be flexible enough and where the performance of a specific architecture could be measured, closer to reality rather than in a...

Fermat and Mersenne N T T s are relatively easy to implement, but unsuitable for many DSP applications, due to small block length over wordlength. This paper presents VLSI design techniques appropriate for a wider range of N T T s , including maximum-length N T T s , and presents a systolic architecture exploiting blocklength factorisation to decompose the architecture into sub-modules, themsel...

The first description of modern cardiopulmonary resuscitation (CPR) included the instruction to compress the chest “about 60 times per minute”1; however, the optimal compression rate was unknown. Franz Koenig is credited with describing the original technique for external cardiac massage, which included a compression rate of 30 to 40 per minute.2 But in the first published description of extern...

BACKGROUND Perioperative fluid restriction might be beneficial in specific clinical settings. In this prospective, randomized and blinded study, we assessed whether peristaltic pneumatic compression of the legs can support restrictive fluid management strategies by reducing intraoperative fluid demand and improving hemodynamic stability. METHODS Seventy patients scheduled for minor surgery we...

The syndrome of celiac trunk compression (or celiac axis compression syndrome) is a nosologic entity that has been recently introduced in the abdominal vascular pathology field based on the clinical-radiological observations by correlating abdominal symptoms caused by the compression of celiac trunk crura (Dunbar et al., 1965). Since then, several cases have been reported describing this syndro...

Data compression is becoming an essential component of high speed data communications and storage. Lossless data compression is when the decompressed data must be identical to the original. Textual substitution methods are among the most powerful approaches to lossless data compression, where repeated substrings are replaced by pointers into a dynamically changing dictionary of strings. We pres...

We consider parallel algorithms for real-time compression of video. Our model of computation is a systolic pipe, where processors are arranged in a linear array (each processor is connected only to its left and right neighbors). The algorithm presented combines quantization techniques with dynamic (adaptive) on-line textual substitution methods for data compression. We first consider an arbitra...

Methods All CMR studies performed for clinical evaluation of pediatric pectus excavatum at our institution were retrospectively reviewed. CMR analysis included evaluation of Haller index, left ventricular (LV) and RV ejection fractions (EF), and indexed LV and RV end-diastolic and end-systolic volumes. The site of maximal compression of the right ventricle (no compression, atrioventricular (AV)...
