State estimation technique for a planetary robotic rover

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
Given the long traverse times and severe environmental constraints on a planet like Mars, the only option feasible now is to observe and explore the planet through more sophisticated planetary rovers. To achieve increasingly ambitious mission objectives

Modelling compressive loading in large‐bodied mammals reveals distinct biomechanical strategies in proboscidean humeri

Journal of Anatomy, EarlyView.
Graviportal proboscideans differ in limb morphology, adopting slender or more robust long bone morphotypes. Finite element analyses (FEA) on extant and extinct taxa reveal functional differences between morphotypes, with robust humeri exhibiting lower peak stress under neutral and off‐axis loading.

Efficient Legged Robot Locomotion Through Optimized Gait Planning for Unstructured Planetary Terrain

IEEE Access
Traditional rovers cannot maneuver easily through challenging environments, which limits their movement and exploration in planetary missions. Legged robots are potential solutions to replace them, but a detailed investigation is required to evaluate the

Theorizing Waste as a Technique of Power in Capitalistic Stakeholder Relations

Journal of Management Studies, EarlyView.
Abstract Waste is an important socio‐ecological challenge of contemporary capitalism, contributing to climate change and environmental degradation. Despite its pervasiveness and its impacts on diverse stakeholders, it yet remains largely underexplored in management and organization studies.

Typical Dream Themes in a Large Internet Sample: A Replication and Extension

Journal of Sleep Research, EarlyView.
ABSTRACT Typical content themes in dreams still defy clear explanation. While a series of studies administering typical dream theme questionnaires mainly to college students point to a surprising consistency in the prevalence of such themes over gender, age, culture, and time, it is still unclear how generalizable such findings are to the larger ...

Small Planetary Rovers

, 1990
Introduction We argue that small rovers on the order of I to 2 Kg are suitable for planetary exploration [Brooks and Flynn 89]. Not only are they extremely cost effective, but they also enable a number of new possibilities for scientific objectives . We

Improving Rover Path Planning in Challenging Terrains: A Comparative Study of RRT-Based Algorithms

Robotics
Autonomous planetary rovers require robust path planning over rough 3D terrains, where traditional metrics such as path length, number of nodes, and planning time do not adequately capture path quality.

That sinkin’ feeling: Environmentally induced distress on a disappearing island

Medical Anthropology Quarterly, EarlyView.
Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent
