Simulation Evaluation of Single Shuttle and Twin Shuttle AS/RS

An Automated Storage and Retrieval System (AS/RS) operates a shuttle with computer process control to execute the storage and retrieval of warehouse stock. It can be equipped with the traditional single shuttle or the newly developed twin shuttle. There has been a significant literature on the comparison of single shuttle systems versus twin shuttle systems. Researchers agree that twin shuttle ...

Quantum shuttle in phase space.

We present a quantum theory of the shuttle instability in electronic transport through a nanostructure with a mechanical degree of freedom. A phase space formulation in terms of the Wigner function allows us to identify a crossover from the tunneling to the shuttling regime, thus extending the previously found classical results to the quantum domain. Further, a new dynamical regime is discovere...

Space Shuttle Technical Conference

Modeling the Space Shuttle

We summarize our methodology for modeling space shuttle processing using discrete event simulation. Why the project was initiated, what the overall goals were, how it was funded, and who were the members of the project team are identified. We describe the flow of the space shuttle flight hardware through the supporting infrastructure and how the model was created to accurately portray the space...

Dynamics of Shuttle Devices

Foreword This thesis is submitted in candidacy for the Ph.D. degree within the Physics Program at the Technical University of Denmark. The thesis describes part of the work that I have carried out under supervision of Antti-Pekka Jauho from the Department of Micro and Nanotechnology. I'm grateful to my supervisor for the very stimulating atmosphere that he has been able to create and maintain w...
