Oxidation of silicon: further tests for the interfacial silicon emission model

The classical description of Si oxidation given by Deal and Grove has well-known limitations for thin oxides (below 200 Ã). Among the large number of alternative models published so far, the interfacial emission model has shown the greatest ability to fit the experimental oxidation curves. It relies on the assumption that during oxidation Si interstitials are emitted to the oxide to release strain and that the accumulation of these interstitials near the interface reduces the reaction rate there. The resulting set of differential equations makes it possible to model diverse oxidation experiments. In this paper, we have compared its predictions with two sets of experiments: (1) the pressure dependence for subatmospheric oxygen pressure and (2) the enhancement of the oxidation rate after annealing in inert atmosphere. The result is not satisfactory and raises serious doubts about the model’s correctness

Collaborative business networks evaluation of technological tools for decision support making

Nowadays, companies are living great difficulties on managing their business due to constant and unpredictable economic market fluctuations. Recent changes in market trends (such as the constant demand for new products and services, mass customization and the drastic reduction of delivery time) lead companies to adopt strategies of creating partnerships with other companies as a way to respond effectively to such difficult economical times. Collaborative Networks’ concept born by the consequence of companies could no longer consider their internal business processes’ management as sufficient and tend to seek for a collaborative approach with other partners for their critical processes. Information technologies (ICT) assumed a major role acting as “enablers” of these kinds of networks, enhancing information sharing and business process integration. Several new trends concerning ICT architectures have been created to support collaborative networks requirements, but still doesn’t exist a common platform to reduce the needed integration effort on virtual organizations. This study aims to investigate the current technological solutions available in the market which enhances the management of companies’ business processes (specially, Collaborative Planning). Finally, the research work ends with the presentation of a conceptual model to answer to the constraints evaluated.

An analysis of the Woodcock Reading Mastery Tests and the Diagnostic Reading Scales for use with hearing-impaired children

This paper examines two individually administered diagnostic reading tests, the Woodcock Reading Mastery Tests and the Diagnostic Reading Scales, to determine their value for use with hearing-impaired children.

Comparison of video and toy reinforcers to motivate infants/toddlers for hearing tests

This paper is a study of the effectiveness between video and toy reinforcer types to motivate infants/toddlers for hearing tests. No significant differences were found between age groups or gender. Toy reinforcers were found to produce on average two more threshold estimates compared to video reinforcers. Variety, color and animation of animals may have contributed to this difference.

Comparing two receptive vocabulary tests: The receptive one word vocabulary test and the peabody picture vocabulary test

This paper discusses a study to determine whether the Receptive One Word Picture Vocabulary Test is more useful than the Peabody Picture Vocabulary Test in assessing the vocabularies of hearing imparied children.
