Spell checking and correction is still in its infancy for the Yorùbá language, existing tools cannot be directly applied to address the problem, as Yorùbá uses diacritics extensively for distinguishing phonemes and for marking tone. A model was formulated as a parallel combination of a unigram language model and a diacritic model to form a dictionary sub-model that can be used by error-detection and candidate-generation modules. The candidate-generation module was implemented as a reverse Levensthein edit-distance algorithm. The system was evaluated by using detection accuracy (calculated from the precision and recall) and suggestion accuracy (SA) as metrics. Our experimental setups compared the performance of the component subsystems when used alone and with their combination into a unified model. The detection accuracies for the different models range from 93.23 to 95.01%, and the suggestion accuracies range from 26.94 to 72.10%. The results indicated that each of the sub-models in the dictionary played different roles.

Thesis concerns assessment of the impact of deposits media that saturate pore spaces on the elastic parameters and resistivity of reservoir rocks. Media that were tested are: gas, oil and water. Batzl & Wang formulas [1992] and formula of Bigelow [1992] were used to make graphs showing changes of parameters. Preceding the calculation, geological structure of the research area is presented. It provides information about gas field Lubliniec – Cieszanów. In the following part, thesis contents information about selected types of tools used to resistivities measurements of rocks along with acoustic logs. The last chapter of thesis is aimed at use of logging results from the Lubliniec – 10 hole, saved as a ‘.las’ file. Data from well logging measurements were used to make velocity models according to formulas of Wyllie [1956] and Raymer – Hunt – Gardner [1980].
