Determination of nutrient salts by automatic methods both in seawater and brackish water: the phosphate blank

9 páginas, 2 tablas, 2 figurasThe main inconvenience in determining nutrients in seawater by automatic methods is simply solved: the preparation of a suitable blank which corrects the effect of the refractive index change on the recorded signal. Two procedures are proposed, one physical (a simple equation to estimate the effect) and the other chemical (removal of the dissolved phosphorus with ferric hydroxide).Support for this work came from CICYT (MAR88-0245 project) and Conselleria de Pesca de la Xunta de GaliciaPeer reviewe

Metaprogramming Techniques for Designing Embedded Components for Ambient Intelligence

Abstract: The design for ambient intelligence (AmI) requires the development and adoption of the novel domain analysis methods and design methodologies. Our approach is based on the domain and application-specific analysis methods adopted from the SW engineering domain, the generic embedded component (EC) model and the metaprogramming (MPG) techniques. The novelty of our approach is that we apply MPG systematically in order to deal with a vast quantity, diversity and heterogeneity of the ECs, raise the level of abstraction in embedded system design, and achieve higher flexibility, reusability and customisability for AmI-oriented design. We provide three case studies and discuss the application of the heterogeneous MPG techniques for designing ECs for AmI. Key words: ambient intelligence, domain analysis, generic embedded component, embedded software, metaprogramming, software generation. 1
