We describe a group of alloys that exhibit "super" properties, such as ultralow elastic modulus, ultrahigh strength, super elasticity, and super plasticity, at room temperature and that show Elinvar and Invar behavior. These "super" properties are attributable to a dislocation-free plastic deformation mechanism. In cold-worked alloys, this mechanism forms(More)
This chapter presents a specification technique based on UML for the design of embedded systems and platforms. It covers stereotypes and extended notations to represent platform services and their attributes in embedded software development. It also presents a design methodology for embedded systems that is based on platform-based design principles. 1.(More)
The objective of this study was to explore the effect of the character of chitosans used, and the regeneration conditions employed on, the yield and physicochemical characteristics of regenerated products. Different concentrations of acetic acid were used to dissolve chitosans of 61.7% and 94.9% degree of deacetylation (DD), and weight-average molecular(More)
Uniform bismuth nanospheres were successfully prepared from bismuth nitrate in the presence of poly(N-vinyl-2-pyrrolidone) (PVP) by solvothermal process. The product was characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, and energy-dispersive X-ray. PVP plays a(More)
Important trends are emerging for the design of embedded systems: a) the use of highly programmable platforms, and b) the use of the Unified Modeling Language (UML) for embedded software development. We believe that the time has come to combine these two concepts into a unified embedded system development methodology. Although each concept is powerful in(More)
