| A comparison with synchronous circuits suggests four opportunities for the application of asynchronous circuits: high performance, low power, improved noise and EMC properties, and a natural match with heterogeneous system timing. In this overview article each opportunity is reviewed in some detail, illustrated by examples, compared with synchronous alternatives, and accompanied by numerous p...

purpose: the aim of this study was to evaluate the effect of two gingival finishing lines (90° shoulder and deep chamfer) on the marginal fitness of two types of full anatomic all-ceramic crowns; zirconia crowns (zikonzhan) and glass ceramic crowns (ips e-max cad) milled with cad/cam system. materials and methods: two dentoform teeth of left maxillary first molar were prepared with chamfer fini...

Rapid prototypings using direct selective laser sintering (SLS) ofmetal/ceramic powders have a great potential for design and fabrication of near net shape of metal/ceramic parts. At presents CO2, Nd:YAG and Excimer are the only possible solutions for the heavy duty manufacturing applications. At the University of Connecticut, researchers advanced the concept of rapid prototyping and other desk...

an important issue in implementation of a gis system is preparation of data to be entered in gis. to produce spatial data for gis using photogrammetric techniques, conventional method is to apply photogrammetric and gis systems individually (off-line procedure). this approach is costly, time consuming and somehow unreliable due to the fact that 3d photogrammetric model is not available at the t...

Coronary artery disease (CAD) is a major cause of morbidity and mortality in modern society. Known risk factors for coronary artery disease include dyslipidemia, hypertension, obesity, dysglycemia, insulin resistance, inflammation, arterial intimal thickening, development of vulnerable plaque and thrombosis. This study compared lipid parameters in CAD patients with healthy individuals to see th...

Performance is no longer the only metric dominating modern system-level design. Power is emerging as major constraint to consider during system development. Consequently, several CAD tools with power estimation capabilities in addition to performance figures have been developed. Among these tools, UNISIM is a simulation framework that enables the architects to rapidly design a new system at dif...

Introduction. Adipose tissue is the largest endocrine organ, composed of subcutaneous (SAT) and visceral adipose tissue (VAT), the latter being highly associated with coronary artery disease (CAD). Expansion of epicardial adipose tissue (EAT) is linked to CAD. One way of assessing the CAD risk is with low-cost anthropometric measures, although they are inaccurate and cannot discriminate between...

The goal of the research is twofold First, the derivation of a design methodology for FIR filters implementation based on Residue Number System (RNS), aiming at power, delay and hardware complexity reduction comparing with conventional binary implementations. Second, a CAD tool development, which generates synthesizable VHDL description of any RNS system design, in automatic way. This tool can ...
