In recent technology nodes,reliability is increasingly considered a part of the standard design flow to be taken into account at all levels of embedded systems design.While traditional fault simulation techniques based on low-level models at gate-and register transfer-level offer high accuracy,they are too inefficient to properly cope with the complexity of modern embedded systems.Moreover,they do not allow for early exploration of design alternatives when a detailed model of the whole system is not yet ava... 相似文献

Blends with different ratios of thermoplastic polyurethane/polypropylene (TPU/PP) were prepared by melt mixing using an internal Haake mixer. Properties of the blends were investigated using SEM micrographs of cryofractures and measurement of the mechanical strength, water absorption, cell culture, and platelet adhesion in vitro tests, which were compared with those of PVC blood bags. The effect of the addition of the ethylene–vinyl acetate (EVA) copolymer on the TPU/PP blend properties was investigated. The results indicated that a TPU/PP/EVA = 80/20/5 blend can be used as a new blood bag material. It was observed that the blend is homogeneous with higher mechanical strength than that of the commercial PVC blood bag. This blend also showed a compatible cell response in contact with L929 fibroblast cells and fewer tendencies to interaction with platelets compared to the PVC blood bag. Although the blends were immissible and no chemical reaction at the interface could be found, the blood compatibility of the blends were improved. © 2003 Wiley Periodicals, Inc.

Recent studies on inorganic/polymer nanocomposites have shown enhancements in thermal, mechanical, and chemical properties
over the neat polymer without compromising density, toughness, and processibility. When nanoparticles are incorporated into
the polymer matrix, significant enhancements in thermal and mechanical properties of the nanocomposite are observed. The present
study is focused on the preparation and characterization of nanosize magnetite-reinforced PU composites, which induces magnetic
properties to a specific thermoplastic polyurethane elastomer. The nanocomposites are prepared and the effects of magnetite
content on thermal, mechanical, and magnetic properties of the nanocomposites are evaluated. Ultrasonication was used to disperse
the nanoparticles and break up any large clumps and aggregates and followed by mechanical mixing. The magnetic nanocomposites
were characterized by FT-IR spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and vibrating
sample magnetometry (VSM). Characterization of the magnetic nanocomposite by FT-IR showed a successful incorporation of magnetite
nanoparticles into the polymeric matrix. TGA and magnetometry of the magnetic nanocomposites revealed the amount of magnetite
that was incorporated into the polymeric phase. Finally, the corresponding magnetization behavior of the nanocomposites was
studied. 相似文献
