The calculations show that the instantaneous frequency of the rolling elements amounted to 18.3 Hz. Figure 4: comparison of noise emission and vibration signals of the damaged bearing of the bearing seating was installed in vertical position of the axle according to an acceleration sensor. In addition to this sensor, the vibration test system consisted of a vibration device for DSA. The vibration data is imported to the analysis in a MATLAB environment. At constant rotational speed, the accelerometer against an acoustic sensor was replaced. The test system described here to the Sound emissions test was used for data collection. Additional information is available at Rick Ross.
The data analysis was carried out using the MATLAB environment. Figure 4 shows the results of the comparison between the signal from the noise and the vibration acceleration signal. As the figure shows, the signal / noise ratio of the noise which is caused by the surface damage of the rolling body is much higher than the signal / noise ratio of vibration acceleration. Figure 5 shows an envelope spectrum of the two signals to narrow-band filtering. As can be seen from the figure, the envelope spectrum of acoustic emission signal has a simpler line structure, from which the characteristic frequency of damage is easier to determine. Figure 5: Comparison of the envelope spectra of sound emission signal and the signal of a damaged bearing vibration acceleration test system for acoustic emission testing combines the outstanding price-performance ratio of the digitizer PCI-9846 and the ease of use through the software. Thereby resulting low costs, a comfortable development environment and a large potential for expansion. The test system was used to evaluate the sound emission signal that produces a roller bearing with surface damage to the bearing in operation.
The results of this test were compared with the results of a conventional vibration test. The comparison shows that the noise has a larger signal-to noise ratio. This shows the great potential of the acoustic emission test for the early detection and diagnosis of rolling bearing damage.

Read How-to programs. Ask the children what to do. Experiment – what would happen if … Note: Expensive parts of the computer – the processor unit and monitor. The mouse and keyboard are much cheaper, even if heaped up. In the case of the laptop there is no cheap parts, except the bag and adapter, and a relative. Repair is difficult, but the machine itself can fix yourself. It also laid the creators.

It can make you a good specialist or your child. The main thing to remember and retain the information. Myth – A computer is needed for complicated things. The computer can calculate and build the spacecraft and control their flight from Earth to design bridges and mnogokilometrovye stoetazhnye skyscrapers, explore the human and diagnosis, as well as many other important and relevant cases. But that's not all. The computer is also used for such simple and necessary in everyday life affairs such as: Correspondence – Send and receive short messages emails Community – Chat Community Voice – Voice Chat Listen to music watching movies reading books to find specific information on the Internet and writing articles, etc. – instead of writing Keeping cars right information in digital form instead of bulky and dusty folders and boxes … and much more – you name it and learn it all very easily and discreetly, if … if you have normal human wish to use, no more. The rest will take care of your inquisitive nature. Sit down at the computer and turn it on. The computer itself will teach you what to do, how to handle it. And if you're still a coward, then let me go ahead and watch the baby after him. Children of all ages – is the most advanced, progressive part of humanity. Only God forbid you make him their comments. No way! You ruin the young shoots and make child in the same funk. And he had in front of the future – his whole life. So, if you are a housewife, and you have all three grades of education, then this is enough to safely use computers and benefit from this huge pleasure. Three-class education enough to read the letter and understood that tells you your computer. Stages of learning computer skills I'm afraid of him! Help me! Show me. How interesting!

Manuel if adaptou soon. It exactly did not like to work and to earn to be without making nothing was excellent. But Jiro was exactly very led. After one work month, it presents to another employee the Manuel. There yes, Manuel if cheered.
She was the same one it faced that it for long time. Manuel was soon facing bichinha and was smoothing the seinhos of it. They were lisinhos, durinhos and well precise. It took off blusinha of it soon and observed them intently. Coisinhas gostosas. Jrio and Manuel invite the girls for noitada.
They take gazelas for the deep one of the house. They take off the hunk clothes and in the girls. All moan of pleasure. Manuel is crazy. How happiness! moans and fungam and says baixinho. They remain there even of madrugadinha. Z Dentist who had travelled, returns more early. It does not find the guards. Where if they had put? As it has the key, opens the gate and enters. It goes direct for the deep ones. It finds the clothes of the four. Stranger. He sees something more strange still I sing in it of the wall and hears gemidinhos. They so were forgotten the life who do not perceive the presence of the master. Z Dentist comes back pra front, opens the door, enters in house and catches one 38. It hides the clothes of them and it opens the door of the engatilhado kitchen with the 38. Cambada of vagabonds. Then I put employed pra here to make my house of motel? Its poor fellows disappear daqui already, before I pass a bullet in the room. They take tremendous a scare and run for the clothes, but cad the parts? Clothes? Then vocs they are worried about clothes? Why then they were bare? Z said Dentist. Please, its Z, was an error, returns our clothes and we will not come back more here – they had said. They leave already daqui, its pilantras. Not I want to see vocs nor spotted of gold. They leave running naked for the street covering the parts without-shames. They had only run a bit and they had found the clothes. They had dressed that quickly and if they had ordered from there, each one blaming the other. Jrio and Manuel go to a small bar in a gas station. There, they talk very and they drink the day almost all. Jrio counts everything that happened with it in the house of Z Dentist. He was a good man very. They had abused very exactly. the girls? Good girls. Jiro knew has them much time. It liked them. Z Dentist would come back behind. They liked all. Only that the sacanagem was very great. Z Dentist would reconsider. At least it was this what they waited.
