This work presents a theoretical analysis for the Black–Scholes equation. Given a terminal condition, the analytical solution of the Black–Scholes equation is obtained by using the Adomian approximate decomposition technique. The mathematical technique employed in this work also has significance in studying some other problems in finance theory. 相似文献

This is a continuation of the article(Comm.Partial Differential Equations 26(2001)965).In this article,the authors consider the one-dimensional compressible isentropic Navier-Stokes equations with gravitational force,fixed boundary condition,a general pressure and the density-dependent viscosity coefficient when the viscous gas connects to vacuum state with a jump in density.Precisely,the viscosity coefficient μ is proportional to ρ^θ and 0〈θ〈1/2,where ρ is the density,and the pressure P=P(ρ)is a general pressure.The global existence and the uniqueness of weak solution are proved. 相似文献

In traditional method of obtaining the radiance of target in infrared image, a target is often considered as an extended source. In that way, we only need the atmosphere transmittance, path radiance, and target apparent temperature to calculate the blackbody equivalent temperature of the target. However, in real infrared system imaging process, the target may be so far from the sensor that the target should be taken as a point source. In that case, the traditional data analysis method is not applicable anymore. A new method of calculating the radiance of small target is presented, which is based on the infrared system imaging theory. And the parameter needed to be input in this method is easily obtained. This method is tested by three different imaging systems. They are Thermal Vision AGEMA 900, AGEMA 1000, and Airborne Surveillance Pod Imaging System. The method is programmed into software, IRIDAS (Infrared Radiation Image Data Analysis Software) version 1.0. This software includes infrared imaging system calibration, atmosphere modification calculation, target and background selection and radiance calculation. This method can be used in infrared data anaylsis, infrared system evaluation and testing, target and background characteristics obtaining. 相似文献

This study investigated the growth behavior of solder interconnect on solder bonding pad. The solder thickness was investigated with respect to parameters including bonding pad area, reflow temperature, solder paste volume, loading, and die size (metallization area). Solder thickness was found to have a maximum value with respect to the ratio of solder paste volume to pad size. Loading and the reflow temperature showed no effect on solder thickness. An enlargement in metallization area reduces the solder thickness, while greater solder paste volume increases the solder thickness 相似文献

The construction and performance characteristics of an ion-selective electrode for fentanyl-drug cation, based on an ion-pair complex with tetrakis[3,5-bis-(trifluoromethyl)phenyl]borate anion in a PVC matrix were studied. A linear response for 1 x 10(-5) mol dm-3 to 1 x 10(-2) mol dm-3 drug with a slope of 57.9 +/- 0.5 mV/decade was established. The optimum pH range was 2 to 6. The lower detection limit was 6.29 x 10(-6) mol dm-3 fentanyl citrate (2.1165 micrograms cm-3 fentanyl). There were negligible interferences from a number of inorganic cations, structural analogues, and some common drug additives in injections. The electrode proposed has been successfully applied to determine fentanyl citrate in injections. The results correlated well with those obtained by the United States Pharmacopoeia standard procedure. 相似文献
