The 27 moons of Uranus (Figure 1) are enigmatic and remain poorly understood. Voyager 2 flew by the Uranus system in 1986, collecting fascinating images of its five largest, tidally-locked ‘classical’ moons (Figure 2), while also discovering a be

This paper explores the interdependance of walking algorithm and limb workspace for the Multi-Appendage Robotic System (MARS). While MARS is a hexapedal robot, the tasks of defining the workspace and walking agorthm for all six limbs can be abstracte

The Multi-Appendage Robotic System (MARS) is a hexapedal robotic platform capable of walking and of performing manipulation tasks. Each of the six limbs of MARS incorporates a three-degree of freedom (DOF), kinematically spherical proximal joint, sim

This paper reports on results obtained from the estimation of a rail cost function using a pooled-time series, cross section of Class I railroads for the period 1974-1986. An analysis is performed of short-run and long-run returns to scale, the exten
