A computational and experimental method for estimating the residual life of gears in inter-repair period is proposed. The based on main provisions theory vibration-pulse diagnostics spur gears, developed at OIM National Academy Sciences Belarus. performance criteria are contact bending endurance teeth. Accounting changes value coefficient internal dynamic load gearing during operation carried o...

Keberhasilan suatu proyek dapat diukur dari dua hal, yaitu keuntungan yang didapat serta ketepatan waktu penyelesaian proyek. Hal ini untuk menyelesaikan dengan tepat maka salah satu harus diperhatikan adalah pemilihan alat berat. Pada penelitian dilakukan mengetahui produktivitas berat, biaya dan dibutuhkan pekerjaan lapis pondasi agregat kelas A digunakan metode Bina Marga Tahun 2018. Hasil a...

It was found that there are two kinds of pyrimidine nucleoside, monophosphokinase deoxythymidine 5'-monophosphate-deoxyuridine 5'-monophosphate (dTMP-dUMP) kinase and cytidine 5'-monophosphate-deoxycytidine 5'-monophosphate-uridine 5'-monophosphate-doexyuridine 5'-monophosphate (CMP-dCMP-UMP-dUMP) kinase, and their molecular weights were calculated to be 46,000 and 26,000, respectively, by gel ...

Data associated with over 9000 accidents involving large trucks and combination vehicles during a two-year period on freeways in the greater Los Angeles area are analyzed relative to collision factors, accident severity, and incident duration and lane closures. Relationships between type of collision and accident characteristics are explored using log-linear models. The results point to signifi...

In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...
