A Discrete Four Stroke Quantum Heat Engine Exploring the Origin of Friction [PDF]

open access: yes, 2001
The optimal power performance of a first principle quantum heat engine model shows friction-like phenomena when the internal fluid Hamiltonian does not commute with the external control field. The model is based on interacting two-level-systems where the

Principles of Magnetohydrodynamical Control of Internal and External Supersonic Flows

open access: yesEnergies, 2022
This paper demonstrates the possibility of active magnetohydrodynamic (MHD) control of supersonic flows containing shock waves. The shock wave configurations that occur at the inlet to a supersonic diffuser and in front of a streamlined semicylindrical ...

The effect of continuous, nonlinearly transformed visual feedback on rapid aiming movements [PDF]

open access: yes, 2008
We investigated the ability to adjust to nonlinear transformations that allow people to control external systems like machines and tools. Earlier research (Verwey and Heuer 2007) showed that in the presence of just terminal feedback participants develop ...

Phase Control of Trapped Ion Quantum Gates [PDF]

open access: yes, 2005
There are several known schemes for entangling trapped ion quantum bits for large-scale quantum computation. Most are based on an interaction between the ions and external optical fields, coupling internal qubit states of trapped-ions to their Coulomb ...

Rules and similarity - a false dichotomy [PDF]

open access: yes, 2005
Unless restricted to explicitly held, sharable beliefs that control and justify a person’s behavior, the notion of a rule has little value as an explanatory concept.

Using the Own Flexibility of a Climbing Robot as a Double Force Sensor [PDF]

open access: yes, 2011
Force sensors are used when interaction tasks are carried out by robots in general, and by climbing robots in particular. If the mechanics and electronics systems are contained inside the own robot, the robot becomes portable without external control ...
