(6) where y is the experimental data yest is the simulation results n is number of given data Fig. 2.
Experimental data adapted from Trinh et al. [10]; (b) Relationship between Deff, t0, and standard error estimate (SEE).
The latter parameters had been estimated through the above process; however, the data are based on constant release stage.
It is needed to validate whether the simulation result is corresponded to experimental data for the decay release stage.
Square dots represent experimental data [10].

Therefore, ontologies improve upon data models, which are mainly used for single applications.
Unlike knowledge representation with lists or databases, ontologies imply hierarchies and are able to describe characteristics and features as well as relations among concepts or data sets.
Phase 2: Data acquisition, situation analysis, problem description and target analysis (UK).
Therefore, the user has to determine the objectives, e.g. the reduction of energy intake per unit produced, the overall energy intake, the reduction of current peaks, etc.

The total nitrogen concentrations of leachate (Recorded as CTN) that located at the bottom of equipments were determined periodically (1 or 2 times per week), the variation laws of CTN that located at the bottom of two landfill equipments with time were researched, and the reasons for the differences were also analyzed; During the period that the degradation of the landfill waste came into a relatively stable stage, the leachate that located at each sampling points of upper, middle and lower horizontal sections of the landfill equipments was collected periodically, and the CTN was determined, the CTN data of each point of upper, middle and lower layers were processed by using Surfer software respectively, and the spacial variation characteristics and differences of two landfill equipments were also discussed.
Therefore, making full use of the functions of biological treatment in landfill site, reduction of total nitrogen concentrations in leachate from the landfill source, to dispose the total nitrogen economically and effectively, and eventually achieving the total nitrogen "harmless, reduction and recyele", had become the hot research topics in landfill disposal technology[2,3].

This paper states the basic theory and algorithm of the model, and provides the experimental results by using the data of China railway passenger volume in 2006 to 2010.
The formulae of calculating the initial value: (5) (6) (7) The equations gives the arithmetic mode of initial value of level, trend and seasonal. is the average of the observational data in one cycle; is the initial value of increment, is the average of the value gets from the second cycle data minus the first cycle corresponding data; is the seasonal change of the first cycle.
The data comes from National Bureau of Statistics of China.
Table 1 shows the factual data of railway passenger volume Table 1 National railway passenger volume in 2006-2010 Jan Feb.
Multiplicative Holt-Winters model is quite suitable for this kind of data.

This fluid dynamic model was widely contrasted against experimental data for two phase gas–liquid systems and served as a base for the development of the three phase gas-liquid-solid systems [13-17].
This hydrodynamic effect causes a reduction in the mass-transfer coefficient.
The volumetric mass transfer coefficient increases with the increasing of the Fr number, nevertheless rapid reduction is found at high Fr number.

However, the reduction of nitrate or nitrite to (main) nitrogen gas contributed the largest share for nitrogen removal in the denitrification process [10].
Thus, the process of nitrate reduction was stimulated and the amount of nitrate removed was increased.
The data for TTC-DHA are shown in Fig. 3.

Model Description and Reduction There are two methods for modeling the quad rotor, one is physical modeling, and the other is the data based modeling.
Considering the disturbance to the motor speed, then the model reduction form as Eq.4 is obtained

In order to solve the problem, we proposed some fusion strategies to enhance the identification precision. 1 Evidence Theory for Damage Localization Information fusion techniques can combine data from multiple information sources and related information from associated databases, to achieve improved accuracies and more specific inferences than could be achieved by the use of a single source alone.
One damage case is assumed with a reduction in the stiffness of individual bars in the structure.
Case 1 has 15% and 20% reduction in the stiffness in elements 7 and 27.
