Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure

Meteoritics &Planetary Science, EarlyView.
Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

Autonomous inspection of underwater structures

Robotics and Autonomous Systems, 2015
In the future our resource on land will be over exploited. The exploration of new resources in the ocean is in progress. Mining will be done on the bottom of the sea. The sea is also a big source of renewable energy. Off shore wind parks and tide plants are built. Also, the major world trade is handled over sea routes and several big harbors.

Guidance of AUVs for Autonomous Underwater Inspection

at - Automatisierungstechnik, 2015
Abstract In this paper, a task-based online path-planning and guidance system of underactuated unmanned underwater vehicles (UUVs) for inspection of underwater infrastructure is described. Whether there are harbor submerged structures, cables, pipes, hydro-technical works, they all need to be checked in relation to structural ...
