A Real-Time Reaction Obstacle Avoidance Algorithm for Autonomous Underwater Vehicles in Unknown Environments

Sensors, 2018
A novel real-time reaction obstacle avoidance algorithm (RRA) is proposed for autonomous underwater vehicles (AUVs) that must adapt to unknown complex terrains, based on forward looking sonar (FLS).

Ground subsidence and polygon development due to thermokarst in the Lena-Aldan interfluve, eastern Siberia, revealed by satellite remote sensing data

Progress in Earth and Planetary Science
Thermokarst development is a topographic change in the landscape that is commonly associated with permafrost degradation in ice-rich permafrost regions.

Mapped polygon pattern geomorphometry from HRSC-AX, 2009, Adventdalen, Svalbard

, 2020
Polygonal systems formed by thermal contraction cracking are complex landscape features widespread in terrestrial periglacial regions. The manner in which cracking occurs is controlled by various environmental factors and determines dimension, shape, and

Higher-point correlators in 𝒩 = 4 SYM: ten-dimensional null polygons

Journal of High Energy Physics
We consider higher-point generalizations of the “octagon” large-charge four-point function in planar 𝒩 = 4 super Yang-Mills theory. These n-point polygon correlators are defined as ten-dimensional null limits of generating functions of n-point ...

Waves and instabilities in rotating free surface flows [PDF]

, 2013
The stability properties of the rotating free surface flow in a cylindrical container is studied using a global stability approach, considering succesively three models. For the case of solid body rotation (Newton’s bucket), all eigenmodes are found to be
