Urban ‘tourism exploration space’: the example of Łódź [PDF]
, 2009 The author refers to the concept of ‘tourism space’ published earlier, and confronts this notion with a definition of ‘urban space’, bearing in mind that both these ‘spaces’ are subspaces of general ‘geographical space’.

Fuzzing File Systems via Two-Dimensional Input Space Exploration
IEEE Symposium on Security and Privacy, 2019 File systems, a basic building block of an OS, are too big and too complex to be bug free. Nevertheless, file systems rely on regular stress-testing tools and formal checkers to find bugs, which are limited due to the ever-increasing complexity of both ...

Comparative Analysis of SWH Retrieval Between BDS-R and GPS-R Utilizing FY-3E/GNOS-II Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingHigh-precision sea surface significant wave height (SWH) data are crucial for advancing oceanic shipping and marine resource development. In this study, we conducted a comparative analysis of parameter sensitivity and accuracy in SWH retrieval between ...

Quantifying Operational Constraints of Low-Latency Telerobotics for Planetary Surface Operations
, 2018 NASA's SLS and Orion crew vehicle will launch humans to cislunar space to begin the new era of space exploration. NASA plans to use the Orion crew vehicle to transport humans between Earth and cislunar space where there will be a stationed habitat known ...

SpaceBok: A Dynamic Legged Robot for Space Exploration
IEEE International Conference on Robotics and Automation, 2019 This paper introduces SpaceBok, a quadrupedal robot created to investigate dynamic legged locomotion for the exploration of low-gravity celestial bodies. With a hip height of 500 mm and a mass of 20 kg, its dimensions are comparable to a medium-sized dog.

Geophysical Research Letters, 2023 The power gap of chorus waves at ∼0.5fce has been discovered for decades, but its generation mechanism is still under debate. Previous studies have revealed that electron plateau distributions are vitally important for the gap formation.

Self-Exploration in Complex Unknown Environments using Hybrid Map Representation [PDF]
arXiv, 2020 A hybrid map representation, which consists of a modified generalized Voronoi Diagram (GVD)-based topological map and a grid-based metric map, is proposed to facilitate a new frontier-driven exploration strategy. Exploration frontiers are the regions on the boundary between open space and unexplored space. A mobile robot is able to construct its map by
