Creation of acoustic vortex knots
Nature Communications, 2020 Although knots in complex optical fields have been realized experimentally, the realization of acoustic vortex knots is still problematic. Here, the authors have demonstrated the creation of acoustic vortex knots by embedding the knot function into a ...

ECOTIRE: A New Concept of a Smart and Sustainable Tire Based on a Removable Tread
Applied SciencesThis paper introduces a new concept of a smart and sustainable tire based on a removable tread band: ECOTIRE. Current tires, though crucial for road information and vehicle control, such as braking, traction, and turning, remain disconnected from ...

Fast Simulation of Vehicles with Non-deformable Tracks
, 2017 This paper presents a novel technique that allows for both computationally fast and sufficiently plausible simulation of vehicles with non-deformable tracks. The method is based on an effect we have called Contact Surface Motion.

Viability-based computation of spatially constrained minimum time trajectories for an autonomous underwater vehicle: implementation and experiments. [PDF]
A viability algorithm is developed to compute the constrained minimum time function for general dynamical systems. The algorithm is instantiated for a specific dynamics(Dubin’s vehicle forced by a flow field) in order to numerically solve the minimum time ...

Influence of tyre pressure on vehicle steady-state lateral dynamics [PDF]
, 2011 This M.Sc. thesis is the result of experience made at the Department of Engineering Design and Production at Aalto University School of Engineering. It examines the steady-state turning of a real vehicle using the handling diagram theory. A test vehicle,
