Current operations of planetary rovers, especially the planning and execution of traverse operations, rely on human analysis and estimation of non-geometric hazards based on images captured by the rover. Despite the use of advanced path planning algorithms capable of avoiding obstacles, this limits daily traverse distances. This paper presents a system concept for planetary rovers capable of sa...

Two stochastic processes describing the contour of simply generated random trees are studied: the contour process as deened by Gutjahr and PPug 9] and the traverse process constructed of the node heights during pre-order traversal of the tree. Using mul-tivariate generating functions and singularity analysis the weak convergence of the contour process to Brownian excursion is shown and a new pr...

A simple, rapid protocol is described for separation of chemical agents into different classes, dependent upon their effects on cell-cycle traverse in line CHO Chinese hamster cells. The technique is a functional assay in that it measures the ability of synchronized cells to traverse the cell cycle on the basis of determination of the labeled and mitotic fractions in autoradiographs prepared fr...

Soon robotic explorers will be able to produce more scientific data than can be transmitted or interpreted efficiently. We present a method for characterizing geology during rover traverse using autonomous data analysis techniques. The strategy detects discrete geologic features in images; distributions of these features constitute a signature that correlates with the geology of each site. Thes...

A new principle of on-line crook measurement for long size rolling stock while running is devised, instead of customary off line static measurement. Rolled steel beams and plates aretransferred on roller tables generally accompanied with the motion of traverse and rotation. Therefore, the following three measuring methodes are described. (1) For the case of both traverse and rotation are neglig...
