Single-crystalline α-Cr 2 O 3 layers were synthesized on a sapphire substrate with basal orientation in laboratory reactor using ultrasonic-assisted chemical vapor deposition the temperature range of 700-850 o C. The influence growth structural quality layer was studied by X-ray diffraction. At 800 C, continuous thickness about 1 μm obtained. transparent visible region slightly greenish tint an...

This paper introduces generic attribute grammars which provide support for genericity, reusability and modularity in attribute grammars. A generic attribute grammar is a component that is easily reused, composed and understood. Attribute grammar based systems may be constructed out of a set of generic components, that can be analysed and compiled separately. We show how to generate deforestated...

Attribute grammars are a framework for defining semantics of programming languages in a syntax-directed fashion. In this paper, we define attribute grammars, and then illustrate their use for language definition, compiler generation, definite clause grammars, design and specification of algorithms, etc. Our goal is to emphasize its role as a tool for design, formal specification and implementat...

In some statistical process control applications, the combination of both variable and attribute quality characteristics which are correlated represents the quality of the product or the process. In such processes, identification the time of manifesting the out-of-control states can help the quality engineers to eliminate the assignable causes through proper corrective actions. In this paper, f...
