Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, EarlyView.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype
Advanced Intelligent Systems, EarlyView.A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Numerical modelling and analysis of hydrostatic thrust air bearings for high loading capacities and low air consumption [PDF]
, 2017 The paper presents a numerical simulation study on hydrostatic thrust air bearings to assess the load capacity, compressed air consumptions, and the dynamic response. Finite Difference Method (FDM) and Finite Volume Method (FVM) are combined to solve the

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

The Age and Origin of Block Deposits in the Victorian Alps, Australia
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Boreas, EarlyView.Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...
