The relationship between relative density of P/M steels and mechanical behavior is also obtained from FEM and compared with the
experimental data.
The ultimate goals in gear modeling may be summarized as the stress analysis such as bending and contact stresses, reduction of surface pitting and scoring, reliability, fatigue life, transmission efficiency and radiation noise.
(1) where E0 is the Young's modulus of the fully dense steel (taken by extrapolating the experimental data to zero porosity, which yielded a value of approximately 201 GPa), and ke is a constant in terms of the Poisson's ratio of the fully dense material, ν0 [3]: ke = 2 − 3ν0
Also, according to experimental data (given in table 1), with 1.3% and 7.2% increase in average porosity, Proportional limit stress systematicaaly decreases 4% and 15.5%.
• According to experimental data (given in table 1), with 1.3% and 7.2% increase in average porosity, Proportional limit stress systematicaaly decreases 4% and 15.5%

Seismic data from the 1999 Adapazarı and Düzce earthquakes were used for the modeling.
Recorded data from the most devastating recent earthquakes that have recently affected Istanbul, namely, the Kocaeli earthquake of August 17, 1999 and the Düzce earthquake of November 12, 1999 were used for the model.
The data was obtained from the Berkeley University-PEER Strong Motion Database [6].
Consequently, the values in literature were adapted with a specific reduction rate when it was seen that the test results were not sufficient to perform a generalization for MOE.
Based on the investigation, storey drift ratios for three alternative models using data from the August 17, 1999 Kocaeli Earthquake are shown in the Table 3 and the resulting graphs are shown in the Figure 13.

Results
In this method, tentative water-leaving radiance is computed for viewing IR spectrometer data with standard atmospheric correction.
Conclusions In this paper, we investigate the antisubmarine detection method with IR spectrometer observation data and the algorithm.
In the near future, we will compare the results with the truth measurement data and also investigate more properly antisubmarine detection model.

From these data, a speed profile for each individual vehicle and for a link could be derived.
Speed data was collected on the weekdays during off-peak hours when the drivers are able to select their speeds independently and it is more likely to be free flow traffic condition.
From these data, vehicle speeds at predetermined points along traffic calmed links were computed.
The extreme values in each data set was considered as mistakes and then excluded from further analysis.
From these data, relationship between mean speed and distance which has been termed a speed profile were developed to reveal the driver’s behavior when negotiating the speed bumps and speed humps.

Reading off the data, the charge-to-breakdown for inducing 50% failure was approximately
QBD(50%) = 0.035 C/cm2 for OSC and = 50 C/cm2 for OS.
Moreover, ignoring the minimum data, all the QBD values were distributed within a factor of ten.
Reduction Guideline.
A QBD(50%) value of 64 C/cm2 was abstracted from the data.
Surprisingly, the best data of all were obtained in this series of experiments.

Cr(VI) reduction to Cr(III), Fe(III) reduction to Fe(II).
A computer using a multi-function data acquisition card performs the control.
A homemade program processes data also, thus the measurement result can be received very quickly, while fast and accurate picture of the measuring process can be obtained during the whole titration.
For monitoring the change of surface layer of the working electrode without physical intervention, the fitting of the measured data to an exponential function is proved to be a convenient tool.
Evaluating the data it can be established that the peaks appeared in the Figure show the measurement of halide ions in an amount, which corresponds, to 588 pg Cl- .

The EIS data were fitted using ZSimpWin (ver. 3.2).
Clearly from the EDX data large percentage of Co coatings consists of Co (83.1%), O (13.2%), S (2.4%), and small amounts of gold (Au) and lead (Pb).
Reduction in Rct means increased corrosion rate.
To characterize the EIS spectral data visually, two circuit models were used to fit the impedance data are shown in Fig. 6d.
Also, the EIS data are listed in Table 2.

It is shown that the simultaneous excitation of the crystals BaF2 pulse accelerated and SE semiconductors in electronic components STE absorption leads to a reduction efficiency of creation of STE and the appearance of fast decaying emission in the UV region of the spectrum.
Spectral and kinetic characteristics of the luminescence caused by radiative annihilation of the STE are in good agreement with published data (lm » 4.1 eV, t » 600 ns).
Consequently, only the simultaneous excitation of the crystals BaF2 pulse accelerated and SE semiconductors in electronic components STE absorption leads to a reduction efficiency of creation of STE and the appearance of fast decaying emission in the UV region of the spectrum.

Therefore, using the method of principal component analysis, index "reduction" process, but should pay attention to the following questions: First, corresponding with the evaluation target, through the necessary "pretreatment" make "negative index" index showed a "index", the index value is greater, the stronger.
Among them, xij is the value of original data; xij’ is the value after the standardization; min{xij} is the minimum value of the original value in the column; max{xij} is the original value maximum value in the column.
