Abstract One of the responsibilities of the oil field corrosion engineer is to correlate laboratory and field test data. With this in mind the principle factors which influence internal corrosion in oil wells (factors which the corrosion engineer must consider) are reviewed here. A laboratory corrosion test method is discussed. Corrosion rate data obtained in the laboratory with three West Texas crude oil and brine systems and the corrosion inhibition obtained in these systems with two organic inhibitors are analyzed and compared. Field corrosion test data for the same three fields are presented. The correlation of laboratory and field test data is discussed in relation to the many variables encountered. It is concluded that the evaluation of the use of inhibitors in some cases may be difficult and may require considerable experience and judgment on the part of the corrosion engineer.

This chapter provides a model for classification of dyslexia, dysgraphia and dyscalculia through analysis of the response of children to treatment. The model is discussed with reference to the types of multivariate treatment applied in a particular programme which works interactively online using an electronic data-base for linking functional difficulties in learning to treatment, and through this to firm diagnosis and classification. In applying the model, initial diagnosis of learning disabilities is treated as provisional, based on functional indicators as well as test data. Firm classification becomes possible through longitudinal assessment, analysis of response to multivariate intervention as well as response to specific programmes. Diagnosis can then be linked both to concessions as well as ongoing treatment.

<p>The paper deals with the re-evaluation of detail categories of lattice girder node joints based on fatigue test data. An elaborate database structure has been set up to evaluate the available fatigue test data in a differentiated way. Detail categories of different types of K and N joints have been investigated and re- evaluated based on the developed data base. Geometric influences on the fatigue strength have been analysed and design recommendations are given.</p>

The article deals with the possibilities to estimate students’ learning styles by applying data mining technologies and the methods suggested by the VARK learning styles model. Using the method of communication, the VARK learning style model in a chosen respondents’ set was estimated. This enables to formulate recommendations for an author of a distance learning course concerning possibilities of personalisation of a particular distance learning course. The concept-baseddata model was chosen to model the research data. The data of the designed e-test data base was processed by applying five stages of data mining.
