Partial differential equation filters are well-known for good processing results, but we must first solve an important question on optimal parameters selection because it affects the denoising results and the stability of the equation directly, which include the selection of diffusivity and optimal stopping time.

Decision model on optimal stopping of business opportunity digging under imperfect information;

The optimal stopping rule on selecting time of stock-operation;

The optimal stopping rule of binomial model with detectingprobability p and over look costs d is provided.

ANN control on optimum on/off time of intermittent air conditioning systems in shallow underground projects;

Selection of optimal stopping time for diffusion filtering based on minimum correlation coefficient;

The calculation formulas of average stopping time (duration of game) on the correlated ramdom walks are given.

Considering the influences of some uncertain error sources under practical engineering condition, it is showed that both rotating time and stopping time of the INS have effect on system acceleration error observations during the calibration process, and may have further effect on inertial instruments error computation.

By introducing theory of the real options and optimal stopping time,This paper analyzes Optimum Time Choice of IPO which is one of the way of exit of venture capitals.

This paper elaborates the optimal stopping time strategy when buying in and selling stocks using the optimal stopping time theory and draws a general conclusion.
