The mechanical properties of dewatered, anaerobically digested sewage sludge were determined from soil laboratory tests. The sludge material is largely composed of organic clay sized-particles, a sizable fraction of which is in an active state of biological digestion which can continue over many years under field conditions. Moderately digested sludge material was found to have a typical specif...

A new method for kinematic calibration of a robot zs presented, based on triaxial measurement of acceleration by a sensor fixed to the robot end-point. The kinematic parameters are evaluated by means of a series of simple tests ( two for each jo in t ) . In these tests each jo in t , except the one under consideration, is kept fired. Acceleration and encoder output are then acquired. Simulation...

Soil variability is a complex attribute that can affect geotechnical engineering design. This paper presents the initial stage of a study into the variability of soil proprieties at the Port of Navegantes, southern Brazil. This study is based on laboratory and field tests that were done as part of the Port enlargement planning. The database consisted of SPT, Vane, soil characterization, oedomet...
