We develop a fast method for solving the one-dimensional wave equation based on geometrical optics. From geometrical optics (e.g., Fourier integral operator theory or WKB approximation) it is known that high-frequency waves split into forward and backward propagating parts, each propagating with the wave speed, with amplitude that is slowly changing depending on the medium coefficients, under t...
With respect to targeting high economic growth rate and lack of financial resources, identifying key sectors and measuring inter-sectoral interactions in in the economy is becoming increasingly important. There is no doubt that the electricity sector in the economy plays a vital role in the development of other sub-sectors and it is expected that there will be a positive relationship between th...
According to a basic prediction made by the Revised Hierarchical Model (RHM), at early stages of language acquisition, strong L2-L1 lexical links are formed. RHM predicts that these links weaken with increasing proficiency, although they do not disappear even at higher levels of language development. To test this prediction, two groups of highly proficie...
