We consider the dividend maximization problem including a ruin penalty in diffusion environment. The additional term is motivated by constraint on strategies. Intentionally, we use different discount rates for dividends and penalty, which causes time-inconsistency. This allows to study types of constraints. For approximation classical surplus process derive an explicit equilibrium strategy asso...

Static and dynamic term structure model of interest rates are studied according to the need for using. As for the static model, exponential splines model is studied and every cash flow of the project is discounted relatively accurately by getting the model of discount rate. As for the dynamic model, a basic model is studied, and the option pricing formula under changing risk-free rate is gotten...

This paper designs an environmental parameters prediction system based on web for greenhouse. The system is designed using the MVC framework, and includes monitoring module and prediction module. The system can obtain the main environmental parameters from sensors, such as light, temperature, humidity, CO2 and so on. Based on mass and energy balance principle, the prediction module of the syste...
