A large-scale intelligent environmental test chamber is designed, that has adjustable effective test volume of 0–30m3, in which the overall test experiments for harmful volatile gases from all kinds of furniture products can be achieved, and the problem of condensation of the large-scale environmental test chamber is solved. The reservation for a number of adjustable features in the control system...
This paper provides a deterministic online algorithm and a randomized online algorithm to search for suitable parameter values in Monte Carlo simulation for derivative pricing which are needed to achieve desired precisions. This paper also gives the competitive ratios of the two algorithms and proves the optimality of the algorithms. Experimental results on the performance of the algorithms are presented...
With the rapid growth of financial markets, many complex derivatives have been structured to meet specific financial goals. But most complex derivatives have no analytical formulas for their prices, e.g., when more than one market variable is factored. As a result, they must be priced by numerical methods such as lattice. A derivative is called multivariate if its value depends on more than one market...
This paper analyzed the statistical data that collected by four air quality monitoring stations in Longyan city, Fujian Province, which indicate that the percentage of sulfur dioxide (SO2), nitrogen dioxide (NO2) and respirable particulate matter (PM10) in atmosphere. The annual average concentrations of the three pollutants are calculated. Then the fuzzy evaluation method is applied to evaluate the...
