It may have form of GIS descriptions like GML or be expressed in any other geospatial numeric data format.
Buildings data were stored as edges attributes.
That functions depend on such factors as energy consumption, sensor data, local specifications of luminosity, traffic intensity, lamps properties and other possible constrains.
A knowledge held by agents of both types consists of local world data (spatial relations, types and shapes of objects, objective functions of a problem, other local agents’ data) and some additional, general information like physical rules of light propagation or lighting points properties.
The important benefit of the approach is the energy saving resulting in better environmental protection and total cost of ownership reduction.

In an ATB model, Card D.9.a is for the applied force/torque function input data.
The discrete control force can be described using a data table.
In ATB, contact properties are represented by two methods, 17 for which the input data are stored in E cards.
This expression can be used to describe the impact dynamics of a variety of seat cushions.9 Those individual functions,, whether linear or nonlinear, can be represented by data tables or by polynomials up to five orders.

The FeNi layers reduction leads to the decrease of saturation magnetization (Ms).
The data are fitted with a linear dependence.
This dependence was fitted to the experimental data for a sample with tFeNi = 50 nm.
It is seen, that the experimental data are fitted satisfactorily as a linear dependence.
Fig. 6 does not include the data for the sample with tFeNi = 1.5 nm, although in the first approximation, this point lies on the presented dependence Hc = f(Ms)–1.

Then we assume damages in elements 7 and 32 occurred after the first measurement of the platform, by the realization of stiffness reduction by 55 and 25%, respectively, and the second test of this platform will be implemented for identifying these damages.
Fig.2 (a) and Fig.2 (b) show the results of damage localization using the first and the second measurement data, respectively, and Fig.2 (c) is the damage localization results using the first and the second measurement simultaneously.
One can find that damages accumulated before the first measurement of the platform could be detected by employing the first measurement data, and damages occurred before the second measurement could be identified too based the second measurement data.
Fig.2 Comparison of damage localization using the first and/or the second measurement data when only two damaged elements before the first measurement Conclusions For offshore platforms served for more than several years, we often face the challenge that no satisfied dynamic test data could be used for damage detection, which maybe the true situation for more than 300 fixed offshore platforms in China.

Introduction Combustion technology is the core technology of the kitchen product, and it is developed gradually by the change of the gas and air mixture, the improvement of the combustion conditions, the reduction of gas emissions (especially CO, NOX) and other conditions [1,2].
Temperature acquisition system and pressure collection system distribute as follows: the experiment data acquisition module evenly distributes into 120° around the burner and divided into four layers from top to bottom.
Start temperature and pressure Real-time data acquisition while ignite the premixed gases, the temperature acquisition module and the pressure acquisition module are connected directly to the computer for real-time data acquisition through the Agilent data acquisition module and interval time is 5s. 1)Ignition Start-up Characteristics Analysis The temperature at the beginning of the ignition 5 minutes increases very fast but a slow increase after 5 minutes knowing from figure 4, this phenomenon illustrates the ignition start-up time is longer than the domestic gas stoves.
Conclusion On the self-designed porous combustion system, the experimental study was carried on in the premixed combustion of multiple ejection/ tangential burner, a large number of experimental data of porous media combustion were obtained.

(a) PCA plots of all fertilizer solutions with Urea, DAP, MOP and MF0 and DI water as the training data set and the MF solutions at 24, 72, 120 and 168 hr after planting D.
Sanderiana as the test data set (Inset: a close-up for Urea and DI water).
The CV data for each loop were pre-processed by extracting averaged current values at a 0.5 V interval in both the forward and reverse scans.
A zero-centered covariance matrix was constructed as an input for the PCA calculations to obtain the score plot (sample classification) for the training data set.
A conversion matrix was constructed from this training data set and was applied to map the test fertilizer solutions.

For each film, five specimens were tested and the average value of them was taken as the resultant data.
All the above measurements were repeated there times and the average value was taken as the resultant data.
That was to say, with the increase of GE of FP, the macromolecular chain of PVA become more irregular because of the more and more graft chains, which might create more defections in the crystallization structure and finally result in further reduction of the tensile strength of the film.
The reason of the reduction of the elongation at break might also due to the graft of FP.
Because the data of the WA were obtained after putting the film into the water for 24h, the process of the water-absorbing was considered as a gradually swollen process accompanying a process of dissolving, which finally reached equilibrium in 24h.

An analysis should substantiate the degree of dissimilarity and independence of: implementation, requirements, algorithms, data, environment, and other potential sources of design error.
A large amount of civil aviation data of different electronic systems has been collected to support table 2.
These system architectures may reduce the complexity of the various items and their interfaces and thereby allow simplification or reduction of the necessary assurance activity9.
The contribution of complexity reduction (i.e. the contribution of common error limitation) depends on the independence of the system architectures, including both function independence and item development independence.
Due to the aircraft design access difficulty, the paper studied limited architectures, the further study could be focused on studying more types of architectures, and on in-service data collection to verify the safety abjectives achieved by assigned level.

Again, to simulate the effects due to the sharp reduction of the pH in the external portion of concrete elements as a consequence of the carbonation phenomena, a 1M aqueous solution of hydrochloric acid is also realised, according to the procedure suggested by Kajorncheappunngam et al. [25] for fibre-reinforced plastic.
Indeed, the dissipation capability simultaneously cross-checks strength and ductility data [30].
However, such modest improvement presents a very limited statistical robustness, since data scattering also grows, thus reducing the design values, accordingly.
Finally, data scattering is consistent with other durability tests for brittle construction materials, being the coefficient of variance in the ultimate strength and strain lower than 20% [32].
The strength threshold is never breached, and the ductility reduction is compensated by a slight strength gain, so that the overall dissipative attitude of the composite is preserved.
