Reversing into a tight space is easy in a car, but on a conventional ship it can feel almost impossible. This explains how propeller flow, rudder placement, and transverse thrust limit control in ...

High-fidelity simulations demonstrate how the number of blades affects the wakes of rim-driven thrusters.

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

Molecular dynamics is a method that uses Newton’s equations of motion to computationally simulate the time evolution of a set of interacting atoms. Such techniques are dependent on a description of ...

Computational chemistry describes the use of computer modelling and simulation – including ab initio approaches based on quantum chemistry, and empirical approaches – to study the structures and ...

Schottel maintains 75-year heritage Celebrations to mark the 75th anniversary of German propulsion specialist Schottel, culminating in a spectacular fireworks display on the River Rhine, incorporated ...

Abstract: To address the issue of the large simulation scale of energy storage-embedded Modular Multilevel Converters (ES-MMC) and the poor versatility of conventional high-performance models, a ...

At Argonne National Laboratory, researchers are trading in old-school approximations for raw supercomputing power, proving ...

Abstract: This paper describes the development, modeling and simulation of a quadruped robot, with an emphasis on generating stable walking patterns through kinematic control and dynamic analysis. The ...

Flow is a state of optimal experience characterized by deep concentration, immersion, and intrinsic enjoyment, and it is widely regarded as a key psychological mechanism that promotes learning ...
