    Notes: Abstract A technique has been developed for predicting the irregular advance pattern often observed as water spreads on the surface of the ground. The technique is a combination of stochastic sketching, potential theory, probability theory, and a mass balance equation in the form of an advance equation. The technique can be used on flat as well as sloping terrain and addresses any form of obstructions or constraints to the flow of the water. The stochastic sketching portion of the technique uses cellular automata with transition probability movement rules to sketch the dynamics of small volume water elements in the defined environment. Randomly selected small volume flow path segments are computed and plotted. The envelope of these segments defines the wetted area and the advance front. Several examples are presented showing the patterns produced for various situations.

    Assessment of lower urinary tract symptoms in women by a self-administered questionnaire: Test-retest reliability (1996)

    Notes: Abstract A self-administered questionnaire assessing female lower urinary tract symptoms and their impact on quality of life is described and validated, on 56 females in six participating departments. The patients answered two identical questionnaires on separate occasions before treatment. Test-retest reliability of the questionnaire, correlation between the symptoms and their troublesomeness, and the reproducibility of this correlation were assessed. The percentage of mistakes in answers to each of the questions varied from 1.8% to 49.1%, mainly owing to missing answers in the item groups: appliances, sexual function and social activities. Test-retest showed a repeat frequency of 50.0%–91.0% for symptoms and 44.6%–82.1% for trouble. A highly significant positive correlation was found between symptoms and trouble, which was most pronounced for questions concerning pain and incontinence. This correlation was consistent within time. The primary validation of this questionnaire is good. Its relevance as a basis for medical priority and clinical decision making remains to be investigated.
