Abstract Road traffic noise needs to be reduced, because traffic volume is increasing every year. The noise generated from a tire is becoming one of the dominant sources in the total traffic noise because the engine noise is constantly being reduced by the vehicle manufacturers. Although the acoustic intensity measurement technology has been enhanced by the recent developments in digital measurement techniques, repetitive measurements are necessary to find effective ways for noise control. Hence, a simulation method to predict generated noise is required to replace the time-consuming experiments. The boundary element method (BEM) is applied to predict the acoustic radiation caused by the vibration of a tire sidewall and a tire noise prediction system is developed. The BEM requires the geometry and the modal characteristics of a tire which are provided by an experiment or the finite element method (FEM). Since the finite element procedure is applied to the prediction of modal characteristics in a tire noise prediction system, the acoustic pressure can be predicted without any measurements. Furthermore, the acoustic contribution analysis obtained from the post-processing of the predicted results is very helpful to know where and how the design change affects the acoustic radiation. The predictability of this system is verified by measurements and the acoustic contribution analysis is applied to tire noise control.

AbstractThis paper describes a fully functional short-term flood prediction system. Its effect has been tested on watershed of Lubieńka river in Małopolska. To use this system it must have a data set also described in this paper. A modification of the system to adopt for predicting flash floods was described. Full operation of the system is shown on example of real flood on Lubieńka river in June 2011.

Religious bigotry pervades our world today. As the 21st century oscillates between what Ramin Jahanbegloo (2015) has described as the politicisation of religion and its accompanying ideologisation, this study examines the vast array of literary creativity and indigenous religion/knowledge from an ecocritical viewpoint. By indigenous, it is meant those systems of knowledge and production of knowledge that are sometimes perceived as antithetical to the Western empirical systems. Encapsulated in myths and mythical wisdom, these indigenous values have at the centre of their philosophical presuppositions a symbiotic strategy that seeks to integrate man with nature. The study examines Wole Soyinka’s Death and the King’s Horseman and D.O. Fagunwa’s Adiitu Olodumare [The Mysteries of God, Olu Obafemi (trans)], in particular, and the indigenous religious/knowledge system that they reiterate, in general, as distinct from the Western monotheistic system in ontological and metaphysical terms. Also, largely because the metaphysical presupposition of Yoruba religion is essentially performance poetry in motion, a carnivalesque perspective is employed to account for the folkloric and other elements of carnival often described as ‘the feast of time, the feast of becoming, change and renewal’.
