The classical theory of centralized dynamic characteristics with eight coefficients is adopted for traditional journal bearings. However, under cantilevered load, distributed along the axial direction will be generated bearing a large aspect ratio (L/D). A double-section loading method simulating shaft bending and excitation was developed, characteristic test-rig large-aspect-ratio set-up, nove...

This paper proposes a maximum-ratio combining sensor fusion scheme for using an extended Kalman filter in the underwater vehicle positioning task by means of communication devices (buoys) providing location information slant-range mechanism, inertial sensors, Doppler velocity log, and pressure absence bearing angle data. The parameter estimation methods all navigation system components are desc...

Due to its high organic matter, moisture content, and low bearing capacity, peat soil needs be stabilized for use as a subgrade. The soybean crude urease calcite precipitation (SCU-CP) method is grouting technique using carbonate biocatalyst. This study aims analyze the effect of SCU-CP density on California ratio (CBR) value obtain best stabilization alternative reducing field’s compaction ene...
