This paper developed feasible AID algorithms based on resampling methods to process imbalanced traffic data.
Data to be removed can be selected in a random way or, more fruitfully, according to particular criteria.
Case Study with I-880 Real Data Data description.I-880 real traffic data in California is selected in experiments to verify the performance of proposed algorithms.
Refinements in data quality promise to improve incident detection performance, therefore, develop feasible methods for data cleaning that available to AID is worthy of further research.

These data are used further for calculation on durability (service life).
They were checked data from X-ray tomography measurements of porosity in castings.
Using data about mechanical properties of cast steel, received by the results of tests control samples, which was cut out from casting test strips, impractical, because that identified indicators of mechanical properties of practically never been able to achieve in the body of the casting work piece.
Also, the processing of the experimental values are used and other data.
Change in the elastic modulus as a function of cast steel the amount shrinkage porosity, ○ - experimental data for low-alloy cast steel [12,13] With the volume of shrinkage porosity of 5-10% (corresponding to the walls of the casting with a thickness greater than 50 mm) is a significant reduction in the mechanical properties, for short-term indicators () is a reduction of up to 30%, and the fracture toughness () to 50%.

Forensic results from a full teardown provide robust data that supplement design and service data to support safety assessments.
Performance measurements are being compared with original design specifications and forensic data can be compared with non-destructive inspection data.
Define end use(s) for data based on scope, resources, and schedule.
Archiving requires transferring this tag and any image data into the database. 3.
As part of iSCRAP, DSTO is developing efficient teardown techniques, including: rapid dismantling methods that do not destroy key information; performance measurements that enable comparison with design specifications; forensic data comparisons with NDI data; and efficient documentation and archiving for easy access to all data.

Also, the aerobic activated sludge containing enriched SOB was immobilized and the kinetics for the sulfur conversion was studied with the immobilized aerobic sludge through treating sulfide (the reduction product of SO42-) in tannery wastewater.
lnv= lnk+ nlnC (3) Equation (2) was integrated and changed as: (4) or lnCtn - lnC0n = kt (5) Equation (5) was the same as: lnCtn = kt+lnC0n (6) When the initial sulfate concentration was 1000mg/L, the sulfate concentration changing with time and the related data were as shown in Table 1.
Table 1 The data of anaerobic reactor t (h) C (mg·L-1) ΔC (mg·L-1) Δt (h) lnc lnv 0 1000 6 688.12 -311.88 6 6.74 3.95 12 477.35 -210.77 6 6.37 3.56 18 380.13 -97.22 6 6.03 3.05 24 261.15 -118.98 6 5.91 2.73 30 199.22 -61.93 6 5.44 2.34 36 157.31 -41.91 6 5.18 1.95 Fig.1 lnv-lnc and its linear fitting in UASB Fig.2 lnC-t and its linear fitting in anaerobic reactor According to Table 1 and Equation (3), a straight line in Figure 1 was obtained by plotting lnv vs lnc.
Kinetics for aerobic reaction It will predict the capacity for the sulfur production if the steady-state dynamic model to produce sulfur from sulfide, the reduction product, in tannery wastewater is established with the contact oxidation pool which contains immobilized aerobic activated sludge.
Table 2 The data of aerobic reactor t (min) C (mg·L-1) ΔC (mg·L-1) Δt (min) lnc lnv 0 0 20 26.37 26.37 20 2.58 0.28 40 37.03 10.65 20 3.46 -0.63 60 43.70 6.68 20 3.66 -0.75 80 52.27 8.56 20 3.87 -0.85 Thus, the reaction dynamic equation for S0 conversion in tannery wastewater was gotten through the immobilized aerobic activated sludge containing enriched SOB: lnC =0.01109 t+3.09996.

The reduction of the material mechanical strength is assessed.
The highest reduction occurred in compressive strength properties.
Tensile testing had cracking occurring around 350MPa as sharp stiffness reduction steps.
The FEA model for simulating the behavior of the laminate with embedded electronics has been developed and validated against experimental data.

New coefficients oxygen permeation equation model is introduced herein this work by fitting the experimental data available in the literature for a LSCF-1991 ion transport membrane.
The values of the pre-exponential coefficient of DV, kf and kr and activation energy for LSCF-1991 membrane have been determined by fitting the experimental oxygen flux data in the work done by kusaba et.al. [7] as a function of temperatures as shown in Fig.2.
Fig.2 Fitting of the experimental data of Kusaba et.al. [7] with the present permeation model.
For this model, the modified reaction rate data by Andersen et.al.[10] are listed in table.2.

Two years data from three different time period before Spring Festival (SF), after SF and after Lantern Festival (LF) in Shenyang city of year 2013 and 2014 was analyzed.
This study collected and analyzed two years (2013 and 2014) data of the PM2.5, PM10, SO2 and NO2 before, between and after two big festival celebrations in Shenyang City to show how festival celebration affects air pollution.
Results could supply useful analytic data and information to set more effective local policies for emission abatement and air pollution control.
Two years data around the Spring Festival were selected and separated to three periods: 10 days till SF (before SF), 10 days after SF and before LF (after SF), 8 days data step over LF festival and 4 days after LF (after LF).
The three period includes: 1) 10 days till SF (before SF, ○); 2) 10 days after SF and before LF (after SF, □); 3) 8 days step over LF festival and 4 days after LF (after LF, △); The non-filling symbols indicate data of 2014 and filling symbols indicate data of 2014.

We focused on the calculation of natural frequencies with data disorder and we have shown how this data disorder affects the location correctness of such frequencies.
Unfortunately Baum have not considered data disorder in his computations.
Weinstein method has not been tested to operate at a data distortion.
What is more, data disorder can have various origins.
On the other hand, if the data are derived from numerical calculations, data disorder is affected by calculations errors such as round-off error and cut-off error.

Introduction In recent years the increasing demands for reducing fuel consumption and release of CO2 gas mostly result in rising requirements concerning the reduction of work piece weight in automobile and aerospace industry.
The high strength metallic materials which allow a reduction of sheet thicknesses have been applied to manufacture heavy duty products.
To validate the reliability of the thermal analysis used in this simulating, AISI 5150H alloy steel was selected based on an available experimental data for this type of steel [9] and a cylindrical workpiece heated by the laser beam was numerically simulated.
The simulation result is in agreement with the published data [9].
As a result, diameter reduction occurs and deviation of internal diameter decreases.

However, they had obvious difference in whole-cell main fatty acid components, cell size, cell morphology, colony color, motility, oxidase, gelatine liquification, nitrate reduction, NaCl tolerance range, pH tolerance range, G+C mole fraction, sole carbon source, sole nitrogen source, antibiotic sensitivity and a source of the strain isolation.
Phylogenetic analyses were performed using the NJ (neighbor-joining) method[14] in the program of the MEGA 4.1 software package after multiple alignments of sequence data by ClustalX 2.0.
Bootstrap analysis was used to evaluate the tree topology of the NJ data by performing 1000 resamplings.
Catalase and nitrate reduction were positive, and oxidase, amylolysis, gelatine liquefication, casein hydrolysis and tyrosine hydrolysis were negative.
Besides, marked difference can also be seen in such aspects as cell size, cell morphology (HNPHT is blunt at two terminals, while A. halophilus is sharp), colony color, motility, oxidase, gelatine liquefication, nitrate reduction, NaCl tolerance range, pH tolerance range, G+C mole fraction, sole carbon source, sole nitrogen source, antibiotic sensitivity and strain source.
