Large-scale hydrological models are important decision support tools in water resources management. The largest source of uncertainty in such models is the hydrostratigraphic model. Geometry and configuration of hydrogeological units are often poorly determined from hydrogeological data alone. Due to sparse sampling in space, lithological borehole logs may overlook structures that are important...

Subgrade moisture content varies with environmental and soil conditions and has significant influence on pavement performance. Therefore, it is important to establish realistic estimates of expected subgrade moisture contents to account for the effects of this variable on predicted pavement performance during the design stage properly. The initial boundary soil suction profile for a given pavem...

The design process of hydraulic drives requires a lot of knowledge and experience although many computer tools are available that aid in various aspects of the design. One of these aspects is the selection of a suitable control strategy and its parameterisation. While being a significant key for the performance of servo-hydraulic drives it is nevertheless often neglected because of lack of know...

This paper studies the precision motion control of single-rod hydraulic actuators with time-varying unknown inertia loads. The swing motion control of a robot arm driven by a single-rod hydraulic actuator (a scaled down version of industrial backhoe loader arm) is used as a case study. During the swing motion, the eeective mass acting on the hydraulic actuator varies greatly with the swing angl...
