Deep Multi-Layer Perception Based Terrain Classification for Planetary Exploration Rovers
Sensors, 2019 Accurate classification and identification of the detected terrain is the basis for the long-distance patrol mission of the planetary rover. But terrain measurement based on vision and radar is subject to conditions such as light changes and dust storms.

Similar or Different? Configurations of Authenticity Across Museum Types
Curator: The Museum Journal, EarlyView.ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.

Long-range navigation for resource-constrained planetary rovers using angle of arrival
Mechanical Engineering Journal, 2015 This study presents a new navigation system consisting of a resource-constrained rover and landers for planetary long-range exploration. During the exploration, they communicate with each other using radio and the rover receives signals from the landers ...

Development and Change, EarlyView.ABSTRACT In the Global North and elite spaces in the Global South, the concepts of Eurocentrism and decolonization have come to be associated primarily with identity and location rather than with capitalism and political economy. This article argues that the reason for this can be traced to what Samir Amin calls ‘inverted Eurocentrism’, which entails a

Decision-Theoretic Control of Planetary Rovers
, 2003 Planetary rovers are small unmanned vehicles equipped with cameras and a variety of sensors used for scientific experiments. They must operate under tight constraints over such resources as operation time, power, storage capacity, and communication ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Ibis, EarlyView.While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Slope traversability analysis of reconfigurable planetary rovers
, 2012 — Future planetary rovers are expected to probe over steep sandy slopes, such as crater rims, where wheel slippage can be a critical issue. One solution to this issue is to mount redundant actuators on the locomotion mechanisms of the rovers such that ...
