Numerous studies reveal that urban favorable amenities potentially contribute to housing prices, but we still lack proper indices to quantify intangible urban disservices and lack the understanding of their economic effects. We attempt to develop remotely sensed indices to reflect these unfavorable and intangible urban disservices. Taking Wuhan in central China as an example, we propose the Thermal...
Owing to the vague fluctuation of financial markets from time to time, the pricing parameters of currency option may occur imprecisely. In this case, it is natural to consider the fuzzy environment of exchange rate markets. In this paper, we introduce fuzzy techniques and obtain the fuzzy version of the Garman-Kohlhagen model. Assuming that the spot exchange rate, domestic interest rate, foreign interest...
In the paper, the mathematical carbide coating growth model was established on the basis of unsteady diffusion theory and regular solution sub-lattice theory. Analysis of the relation between the thickness of the vanadium-carbide layer and immersion time, salt bath temperature and type of substrate was conducted. Compared with the experimental results, this method proved very successful.
